Minerals People Over 50 Often Miss – Page 35

1. Calcium

Calcium plays a pivotal role in maintaining bone density and supporting muscle contraction, nerve signaling, and blood clotting. After age 50, the body’s ability to absorb calcium declines, increasing the risk for osteoporosis—a condition where bones become fragile and more likely to break. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, an estimated 10 million Americans have osteoporosis, with millions more experiencing low bone mass.

Signs of calcium deficiency can be subtle at first, manifesting as muscle cramps, numbness, or tingling in the fingers. Over time, it can lead to frequent fractures, poor posture, and even dental issues.
To maintain healthy calcium levels, focus on dietary sources like low-fat dairy products, fortified plant-based milks, leafy green vegetables, and almonds. Some fish, such as sardines and salmon (with bones), are also excellent sources.

Yogurt, milk, and cheese
Kale and broccoli
Fortified tofu and orange juice
Sardines and canned salmon (with bones)

Regular weight-bearing exercise and sufficient vitamin D intake further help the body utilize calcium effectively.

2. Magnesium

Magnesium is essential for more than 300 biochemical reactions in the body, notably nerve signaling and maintaining a steady heart rhythm. As we age, magnesium absorption declines, and dietary intake often fails to meet recommended levels—especially among older adults. According to the National Institutes of Health, many people over 50 consume less than two-thirds of the recommended daily magnesium.

Deficiency may present as muscle twitches, fatigue, irregular heartbeat, or even cognitive changes. These signs are often mistaken for other health issues, so magnesium status can go unchecked.
Fortunately, increasing your intake is straightforward: focus on adding more whole grains, nuts, seeds, and leafy greens to your meals. Black beans, avocados, and dark chocolate are also magnesium-rich options.

Almonds and cashews
Spinach and Swiss chard
Whole wheat bread and brown rice
Black beans and pumpkin seeds

Regularly choosing these foods may help restore optimal magnesium levels, supporting both neurological and cardiovascular health as you age.

3. Potassium

Potassium is vital for maintaining healthy blood pressure, balancing fluids, and ensuring proper muscle and nerve function. As we age, potassium intake often falls short, partly because of decreased fruit and vegetable consumption or certain medications that increase potassium loss. According to the Centers for Disease Control and Prevention, low potassium is linked to higher risk of hypertension and cardiovascular issues.

Consider Jane, a 62-year-old woman who experienced persistent fatigue and muscle weakness. After routine blood work, her doctor discovered low potassium levels, which were contributing to her elevated blood pressure. By increasing her intake of potassium-rich foods and adjusting her medications, Jane saw improvements in both her energy levels and blood pressure readings.

Bananas and oranges
Sweet potatoes and spinach
Beans and lentils
Avocados and tomatoes

If you notice symptoms like muscle cramps, irregular heartbeat, or chronic fatigue, consult your doctor before making significant dietary changes, as both low and high potassium can be dangerous—especially for those with kidney or heart conditions.

4. Zinc

Zinc is a key mineral for immune system function and wound healing. As people age, the risk of deficiency increases due to reduced dietary intake or diminished absorption. According to the National Institutes of Health, nearly 35% of older adults may not get enough zinc—impacting their ability to fight infections and recover from injuries.

Signs of zinc deficiency are often subtle, including delayed wound healing, frequent colds or infections, loss of appetite, and even changes in taste or smell. These symptoms might be dismissed as normal aging, but persistent issues could indicate a real need for more zinc.
To boost intake, focus on foods naturally high in zinc. Animal sources are more readily absorbed, but plant-based options can also contribute to daily needs.

Oysters and beef
Poultry and pork
Chickpeas and lentils
Pumpkin seeds and cashews

If you have ongoing immune issues or slow wound healing, ask your healthcare provider about checking your zinc levels and possible supplementation.

5. Iron

Iron is critical for oxygen transport throughout the body, forming the backbone of hemoglobin in red blood cells. As people age, iron deficiency becomes more common due to factors such as reduced dietary intake, chronic illnesses, or certain medications. According to the Centers for Disease Control and Prevention, anemia—often caused by low iron—affects a significant portion of adults over 65.

Symptoms of iron deficiency anemia include persistent fatigue, weakness, pale skin, and shortness of breath. These symptoms may be mistaken for general aging, but undiagnosed anemia can have serious health implications, especially for heart and cognitive function.
Regular screening for iron levels is wise, particularly if you notice symptoms or have risk factors such as chronic disease.

Lean red meats and poultry
Seafood (especially clams and oysters)
Spinach and fortified cereals
Beans, lentils, and tofu

To improve absorption, pair iron-rich foods with vitamin C sources like citrus fruits or bell peppers. Always consult your doctor before starting iron supplements, as too much iron can be harmful.

6. Selenium

Selenium is a trace mineral with powerful antioxidant properties, helping to protect cells from damage and support thyroid function. In adults over 50, inadequate selenium intake can compromise immune health and increase susceptibility to oxidative stress. Interestingly, selenium content in food depends heavily on the selenium concentration in regional soils, which means people in certain areas may be at higher risk for deficiency.

According to the National Institutes of Health, selenium deficiency is rare in the United States but does occur, especially in regions with selenium-poor soils or among individuals with restricted diets. Signs of low selenium include muscle weakness, fatigue, and impaired cognitive function—though these symptoms are often subtle and easily overlooked.
To ensure adequate selenium intake, focus on incorporating a variety of nutrient-rich foods into your diet.

Brazil nuts (one or two nuts provide a daily dose)
Seafood, such as tuna and sardines
Eggs and poultry
Whole grains and sunflower seeds

Because selenium is needed only in small amounts, a balanced diet is usually sufficient. If you have dietary limitations, consult your healthcare provider about potential supplementation.

7. Iodine

Iodine is essential for thyroid hormone production, which regulates metabolism, energy, and growth. As people age, maintaining adequate iodine becomes increasingly important to support healthy thyroid function and prevent disorders such as hypothyroidism. According to the National Institute of Diabetes and Digestive and Kidney Diseases, thyroid disorders are more common in older adults, often presenting as unexplained fatigue or weight changes.

Iodine deficiency can lead to an enlarged thyroid gland (goiter), sluggishness, sensitivity to cold, and even cognitive decline. Because symptoms can be vague, they may go unnoticed or be mistaken for other age-related issues.
To monitor your levels, regular checkups and thyroid function tests are recommended, especially if you have a family history or symptoms of thyroid dysfunction.

Iodized salt
Seafood, such as cod and shrimp
Dairy products
Eggs

Most people in the U.S. get sufficient iodine from iodized salt, but those who avoid salt or animal products should pay extra attention to their intake. If concerned, discuss iodine status with your healthcare provider.

8. Phosphorus

Phosphorus is a crucial mineral for bone formation and energy metabolism, working closely with calcium to build strong bones and teeth. It also helps convert food into energy and supports the structure of cell membranes. While most adults consume enough phosphorus, certain populations—especially older adults on specific medications—are at risk for deficiencies or imbalances.

According to the National Institutes of Health, diuretics, antacids, and some diabetes medications can reduce phosphorus absorption or increase its loss from the body. Symptoms of low phosphorus may include muscle weakness, bone pain, and fatigue, but can be subtle and easily overlooked.
The best way to ensure adequate phosphorus intake is a varied diet that includes both animal and plant sources.

Meat, poultry, and fish
Dairy products like cheese and yogurt
Eggs
Beans, lentils, and nuts

Overconsumption is also possible, particularly from processed foods with phosphate additives. If you use medications that may affect phosphorus, periodic blood tests and dietary review with your healthcare provider are recommended.

9. Copper

Copper is a trace mineral essential for the formation of red blood cells and the maintenance of healthy nerves and immune function. It supports iron absorption, antioxidant defense, and the development of connective tissue. In older adults, copper deficiency can occur due to poor dietary intake or interference from supplements like excessive zinc.

Symptoms of copper deficiency are often vague, including fatigue, frequent infections, numbness or tingling in the hands and feet, and problems with balance. In severe cases, anemia and neurological issues may develop. According to the National Institutes of Health, deficiency is rare but can be overlooked, especially in those with digestive disorders or who take high-dose zinc supplements.
A balanced, varied diet generally provides enough copper for most people.

Shellfish, especially oysters
Nuts and seeds (cashews, sunflower seeds)
Whole grains
Dark chocolate and potatoes

If you experience unexplained neurological or blood-related symptoms, ask your healthcare provider about copper status—especially if you are on long-term supplements or have underlying digestive issues.

10. Chromium

Chromium is a trace mineral that plays a key role in blood sugar regulation by enhancing the action of insulin. As people age, chromium levels can decline due to dietary changes, decreased absorption, or chronic health conditions. This decline may contribute to impaired glucose control, which is especially concerning in older adults at risk for type 2 diabetes.

Research suggests that many older adults consume less chromium than recommended, as noted by the National Institutes of Health. Symptoms of deficiency are not always obvious but can include poor blood sugar control, increased cravings for sweets, and low energy levels.
While chromium supplementation is marketed for diabetes and weight management, its effectiveness remains uncertain for most people.

Broccoli and green beans
Whole grains
Grape juice and potatoes
Lean meats

It’s best to prioritize chromium from a balanced diet. Talk to your healthcare provider before considering supplements, especially if you have diabetes or take medications affecting blood sugar.

11. Manganese

Manganese is a trace mineral essential for metabolism, bone development, and antioxidant defense in the body. It activates enzymes involved in digesting carbohydrates, amino acids, and cholesterol, and helps neutralize free radicals. According to the National Institutes of Health, most adults in the U.S. get adequate manganese, though those with very restricted or unbalanced diets—such as some older adults—may fall short.

Deficiency is rare, but when it occurs, it can lead to poor bone health, skin problems, or changes in metabolism. Conversely, excessive manganese from supplements or contaminated water can be harmful, so balance is important.
To support optimal health, include a range of plant-based foods rich in manganese in your daily meals.

Whole grains (brown rice, oats, whole wheat bread)
Nuts (pecans, hazelnuts)
Legumes (chickpeas, lentils)
Leafy greens (spinach, kale)

For most older adults, a varied and balanced diet is sufficient to meet manganese needs. Be mindful of supplement use and consult your healthcare provider if you have concerns about your intake.

12. Molybdenum

Molybdenum is a trace mineral with a critical but often overlooked role in human health. It acts as a cofactor for several important enzymes, helping to break down amino acids and detoxify harmful substances in the body. Though deficiencies are extremely rare, they can lead to neurological symptoms, rapid heartbeat, and increased sensitivity to certain chemicals.

According to the National Institutes of Health, most people—even those over 50—get adequate molybdenum from a regular diet. Deficiency is usually only seen in individuals with specific genetic disorders or severe malnutrition.
For older adults, focusing on a varied diet ensures you receive enough molybdenum without needing supplementation.

Legumes (lentils, beans, peas)
Whole grains (barley, oats, wheat germ)
Nuts
Dairy products

Because the body needs only tiny amounts, a balanced meal plan is typically sufficient. If you have a medical condition that affects digestion or absorption, discuss your nutritional status with your healthcare provider.

13. Fluoride

Fluoride is best known for its role in protecting dental health by strengthening tooth enamel and reducing the risk of cavities. For older adults, maintaining adequate fluoride intake remains important, as enamel can wear down with age, increasing vulnerability to tooth decay and sensitivity.

In the United States, most public water supplies are fluoridated, which has been shown to significantly reduce dental caries rates, according to the Centers for Disease Control and Prevention. However, those who rely on well water, bottled water, or live in areas without fluoridation may not receive enough fluoride through water alone.
Supplementation is generally only recommended if a healthcare provider determines you are at risk for deficiency or have a history of frequent cavities.

Fluoridated drinking water
Toothpaste and mouth rinses containing fluoride
Tea and some seafood

If you’re unsure about your fluoride intake—especially if you have dental issues—ask your dentist whether supplementation or topical treatments would benefit your oral health.

14. Sodium

Sodium is vital for fluid balance, muscle contraction, and nerve function. However, the right balance is crucial, especially for people over 50. Too much sodium is linked to high blood pressure, stroke, and heart disease, while too little (hyponatremia) can cause headaches, confusion, and muscle cramps.

The Centers for Disease Control and Prevention reports that most Americans consume far more sodium than recommended, mainly from processed and restaurant foods. For older adults, excess sodium poses a greater risk due to age-related changes in kidney function and increased susceptibility to high blood pressure.
On the other hand, those on very restrictive diets or certain medications may experience sodium deficiency, which can also be dangerous.

Limit processed foods (canned soups, deli meats, frozen meals)
Read food labels for sodium content
Flavor foods with herbs and spices instead of salt
Stay hydrated, especially during hot weather or illness

Strive for balance—don’t eliminate sodium, but be mindful of intake. Consult your healthcare provider about your personal sodium needs, especially if you have heart or kidney concerns.

15. Chloride

Chloride is an essential mineral that works closely with sodium and potassium to help maintain the body’s acid-base balance and proper fluid levels. It also plays a critical role in digestion by forming part of hydrochloric acid in the stomach, which aids in breaking down food and absorbing nutrients.

According to the National Institutes of Health, most adults get sufficient chloride from table salt (sodium chloride). However, older adults taking diuretics for blood pressure or heart conditions may lose chloride more rapidly, increasing the risk of hypochloremia (low chloride levels). Symptoms can include dehydration, muscle weakness, or irregular heartbeat.
Proper hydration is the best way to help maintain chloride balance, especially if you’re on medications that affect electrolyte levels.

Drink enough water throughout the day
Include moderate amounts of table salt if approved by your doctor
Eat foods like tomatoes, olives, and seaweed
Monitor for signs of dehydration, particularly in hot weather or during illness

If you’re on diuretics or have a history of electrolyte imbalances, ask your healthcare provider about monitoring your chloride and hydration status regularly.

16. Silicon

Silicon is gaining recognition for its emerging role in bone health and the maintenance of connective tissue, particularly as we age. Research suggests that silicon contributes to collagen formation, which is essential for strong bones, skin, and joints. Some studies indicate that higher silicon intake may be linked to improved bone mineral density, a key factor in reducing fracture risk among older adults.

While the human body requires only small amounts, older adults may benefit from ensuring adequate intake, especially since bone loss and joint issues become more prevalent with age. According to a review in the Journal of Nutrition, Health & Aging, dietary silicon appears to be associated with better bone health, though more research is needed to confirm optimal intake levels and mechanisms.
Silicon is found primarily in plant-based foods, especially whole grains and certain vegetables.

Whole grain breads and cereals
Bananas and green beans
Oats and barley
Beer (in moderation) and mineral water

Incorporating more plant-based foods into your diet is a practical way to support connective tissue and bone health as you age.

17. Boron

Boron is a lesser-known mineral, yet it plays an important role in supporting bone strength and cognitive function. Research suggests that boron aids in the metabolism of minerals like calcium, magnesium, and vitamin D—key nutrients for bone maintenance. Its influence on brain health is also being explored, with some studies indicating benefits for mental alertness and memory.

A review published in the Journal of Trace Elements in Medicine and Biology highlights that postmenopausal women may see improved bone density and reduced risk of osteoporosis with higher boron intake. Although the body needs only small amounts, dietary intake can vary widely based on food choices.
Boron is primarily found in plant-based foods, making a varied diet essential.

Prunes and raisins
Avocados and apples
Almonds and peanuts
Leafy green vegetables

To help protect bone and brain health as you age, include a range of fruits, nuts, and vegetables—simple dietary tweaks that can yield lasting benefits.

18. Vanadium

Vanadium is a trace mineral involved in glucose metabolism and the regulation of blood sugar levels. While laboratory studies suggest vanadium may mimic some actions of insulin, the relevance of these effects in humans—especially older adults—remains under investigation. There is currently no established daily requirement, and vanadium deficiency is not recognized as a health risk in humans.

The National Institutes of Health notes that most people consume sufficient vanadium through a typical diet, and research on supplementation is inconclusive and sometimes raises safety concerns. High-dose vanadium supplements can cause side effects such as gastrointestinal distress and may interact with certain medications.
For older adults, the safest strategy is to obtain vanadium naturally through a balanced diet rather than supplements.

Mushrooms
Black pepper
Shellfish
Whole grains and parsley

If you are considering vanadium supplements for blood sugar control, consult your healthcare provider first. Currently, food sources are considered both safe and sufficient for healthy aging.

19. Nickel

Nickel is a trace element with a minor but essential role in human health, particularly in supporting enzyme systems involved in metabolism. While the body requires only very small amounts, nickel is found naturally in many foods, and deficiency is extremely rare. However, it is important to be aware of nickel sensitivity or allergies, which can cause skin reactions and, in rare cases, digestive symptoms.

According to the Agency for Toxic Substances and Disease Registry, nickel allergy is one of the most common contact allergies, especially in women. Symptoms typically arise from skin contact with nickel-containing jewelry or household items but can sometimes occur with high dietary intake.
For most older adults, nickel intake from food is not a concern, but those with known allergies may need to limit certain foods and avoid exposure.

Chocolate and cocoa
Nuts, especially cashews and hazelnuts
Lentils and soybeans
Whole grains and some teas

Aim for a balanced diet, and if you suspect a nickel allergy, discuss food choices and testing with your healthcare provider for best results.

20. Cobalt

Cobalt is a vital component of vitamin B12 (cobalamin), which is essential for healthy nerve cells, red blood cell formation, and DNA synthesis. The body does not use cobalt directly but relies on it as part of the vitamin B12 molecule. Deficiency is rare in those who consume animal products, as B12 is primarily found in meat, dairy, and eggs.

Older adults and those following vegetarian or especially vegan diets are at higher risk for B12 deficiency, since plant foods provide little or no natural B12. According to the National Institutes of Health, B12 deficiency can lead to symptoms such as fatigue, memory loss, numbness, and anemia. The risk increases with age due to decreased stomach acid, which impairs absorption.
Monitoring B12 status is important for seniors, particularly if they avoid animal products.

Beef, poultry, and fish
Dairy products and eggs
Fortified cereals and plant-based milks

If you follow a vegetarian or vegan diet, discuss B12 screening and supplementation with your healthcare provider to prevent long-term complications related to cobalt deficiency.

21. Sulfur

Sulfur is an essential element found in all living tissues, primarily as a component of certain amino acids (methionine and cysteine) and vitamins (biotin and thiamine). These sulfur-containing compounds play vital roles in protein synthesis, enzyme activity, and detoxification processes within the body. Sulfur is not typically tracked as a dietary requirement because it is naturally present in foods rich in protein.

Animal-based foods—such as meats, poultry, fish, eggs, and dairy—are considered the best sources of highly bioavailable sulfur amino acids. Plant-based foods, including legumes, nuts, garlic, onions, and cruciferous vegetables, also contribute significant amounts, though their sulfur content may be less concentrated than that of animal sources. According to the National Institutes of Health, most people receive adequate sulfur from a regular, protein-rich diet.
There are no established recommendations for sulfur supplementation because deficiency is rare in individuals consuming sufficient protein.

Eggs and dairy products
Chicken, beef, and fish
Garlic, onions, broccoli, and Brussels sprouts
Legumes and nuts

To ensure optimal sulfur intake, prioritize a balanced diet with a variety of protein sources from both animal and plant origins.

22. Lithium

Lithium is a trace element best known for its use in prescription medications for mood stabilization, especially in bipolar disorder. In trace amounts, lithium is present in food and drinking water, and emerging research suggests it may play a subtle role in mood regulation and cognitive health, particularly in older adults.

According to studies reviewed by the National Institutes of Health, low environmental lithium exposure is linked to a higher risk of mood disorders and cognitive decline in certain populations. However, the precise biological role of lithium at dietary levels remains under investigation, and there is insufficient evidence to recommend supplementation for the general population.
Most people receive small, safe amounts of lithium from vegetables, grains, and water. High-dose lithium supplements or medications should only be used under strict medical supervision due to the risk of toxicity.

Vegetables (potatoes, tomatoes)
Grains and cereals
Some mineral waters

For those concerned about mood or cognitive changes, consult your healthcare provider before considering any lithium supplement, as safe intake is best achieved through a balanced diet.

23. Germanium

Germanium is a trace element that has generated controversy in the health and wellness community. While it naturally occurs in small amounts in some foods, its biological role in human health is not well established. Some supplements marketed for immune support or anti-aging benefits contain germanium, but these claims are not supported by strong scientific evidence.

The National Institutes of Health warns that germanium supplements, particularly inorganic forms, have been linked to serious side effects, such as kidney damage and even death. Older adults may be especially vulnerable to these risks due to age-related declines in kidney function and increased likelihood of chronic conditions.
Natural dietary sources, such as garlic, shiitake mushrooms, and some vegetables, provide only trace amounts and are considered safe.

Garlic and onions
Shiitake mushrooms
Ginseng and aloe vera
Whole grains

Exercise caution with germanium supplements, especially if you have kidney or liver issues. For older adults, it is best to avoid supplementation and rely on a balanced diet.

24. Tin

Tin is a trace mineral with a minor and poorly understood biological role in human health. While small amounts of tin occur naturally in foods—such as grains, legumes, and some vegetables—there is no established dietary requirement, and its necessity for human nutrition remains uncertain.

More pressing for older adults is the issue of tin contamination from canned foods. According to the World Health Organization, poorly manufactured cans can leach excess tin into food, sometimes causing gastrointestinal upset. The risk is higher in acidic foods like tomatoes or fruit juices, especially when cans are damaged or improperly stored.
To minimize exposure, select products from reputable brands and avoid using cans that are dented, rusted, or bulging.

Choose fresh or frozen produce over canned
Rinse canned foods before eating
Store canned goods in cool, dry places
Check cans for damage before purchase or use

While normal dietary tin intake is not harmful, taking practical steps to limit contamination is especially wise for older adults with sensitive digestive systems.

25. Silver

Silver has a long history of use in medicine, particularly for its antimicrobial properties in wound dressings and medical devices. While it is effective in these external applications, silver serves no nutritional purpose in the human body and is not considered an essential mineral for health.

Despite this, colloidal silver products are sometimes marketed as dietary supplements claiming to boost immunity or treat various illnesses. The U.S. Food & Drug Administration strongly warns against their use, as ingesting silver can lead to a permanent bluish-gray discoloration of the skin (argyria) and may cause kidney, liver, or neurological problems—risks that are especially concerning for older adults.
There is no evidence supporting the safety or effectiveness of colloidal silver for any health condition.

Avoid ingesting colloidal silver products
Use silver only as prescribed in medical wound care
Be cautious of supplements with unproven claims

For healthy aging, focus on proven nutrients and avoid silver-based supplements, which offer no benefit and pose real health risks.

26. Gold

Gold has long fascinated people for its beauty and value, but its biological relevance in human health is minimal. Gold does not play a natural role in bodily functions, and the body does not require it as a nutrient. However, gold compounds have been used in medicine, particularly in the treatment of certain autoimmune conditions like rheumatoid arthritis.

According to the American College of Rheumatology, injectable gold salts were once prescribed to reduce inflammation in joint diseases, but their use has declined with the advent of more effective treatments and fewer side effects. There is no scientific basis for claims made by some supplements that ingesting gold can improve vitality, cognitive function, or longevity.
Ingesting gold, particularly in the form of colloidal gold or unregulated supplements, can be risky and offers no proven health benefit.

Avoid gold-based dietary supplements
Use gold compounds only under medical supervision
Be wary of unproven health claims related to gold

For older adults, focus on nutrients with established benefits and avoid gold supplements, which have no role in nutrition or healthy aging.

27. Lead (as a contaminant)

Lead is a toxic heavy metal with no safe level of exposure for humans. While much attention is paid to childhood lead poisoning, older adults are also vulnerable. Seniors may face higher absorption and retention rates due to changes in bone metabolism, and chronic exposure can lead to serious health problems including high blood pressure, kidney dysfunction, and cognitive decline.

According to the Centers for Disease Control and Prevention, common sources of lead exposure include old paint, contaminated water from lead pipes, certain imported products, and even some traditional remedies. Because symptoms of low-level lead poisoning can be subtle—such as fatigue, irritability, or memory issues—they may go unrecognized in older adults.
Minimizing exposure is crucial for lifelong health.

Drink filtered or tested tap water
Avoid using old ceramic dishes or cookware with lead-based glazes
Check for lead hazards before renovating older homes
Be cautious with imported goods and traditional medicines

If you suspect lead exposure, talk with your healthcare provider about testing and appropriate interventions to protect your health.

28. Arsenic (as a contaminant)

Arsenic is a toxic element with well-documented health risks, including increased risk of cancer, cardiovascular disease, and neurological problems. Chronic exposure is particularly concerning for older adults, who may already face heightened vulnerability due to age-related changes in metabolism and organ function.

According to the Centers for Disease Control and Prevention, arsenic is most commonly encountered through contaminated drinking water, especially from private wells, and in certain foods such as rice, seafood, and some fruit juices. Long-term, low-level exposure can have cumulative effects and is often undetectable without specific testing.
Prevention requires awareness and proactive measures to limit intake.

Test private well water for arsenic regularly
Rinse rice thoroughly before cooking and use plenty of water
Vary your grains, choosing alternatives like quinoa or barley
Check local advisories about seafood and produce

If you live in an area with known arsenic issues or are concerned about dietary exposure, consult your healthcare provider or local health department for guidance and possible testing.

29. Aluminum (as a contaminant)

Aluminum is the most abundant metal in the earth’s crust and is widely used in food packaging, cookware, and medications. While the health effects of aluminum exposure are debated, some studies have linked high intake to neurological concerns, especially in older adults, though a definitive causal relationship has not been established. The Centers for Disease Control and Prevention notes that most people are exposed to low levels of aluminum daily, primarily through food and drinking water.

Aluminum can leach into food from cookware, especially when cooking acidic foods like tomatoes or citrus. It is also present in some antacids, baking powders, and processed foods. While the body eliminates most ingested aluminum, those with kidney impairment or advanced age may retain more, increasing potential risk.
To minimize unnecessary exposure, consider a few simple precautions.

Choose stainless steel or glass cookware over aluminum
Avoid cooking or storing acidic foods in aluminum containers
Check medication labels for aluminum content
Limit processed foods with additives

If you have specific health concerns or kidney issues, discuss aluminum exposure and safe alternatives with your healthcare provider.

30. Cadmium (as a contaminant)

Cadmium is a toxic heavy metal that poses significant risks to kidney and bone health, particularly in older adults who may already have reduced organ function. Chronic exposure can lead to kidney damage, loss of bone density, and an increased risk of fractures. The Centers for Disease Control and Prevention warns that cadmium accumulates in the body over time, making lifelong exposure particularly concerning for seniors.

Major sources of cadmium include cigarette smoke, contaminated soil, certain shellfish, organ meats, and foods like rice and leafy greens grown in polluted areas. While dietary exposure is typically low, it can add up over time, especially if you consume foods from high-risk regions or are exposed to industrial pollution.
Minimizing exposure is crucial for protecting long-term kidney and bone health.

Avoid smoking and secondhand smoke
Wash fruits and vegetables thoroughly
Choose seafood from reputable sources
Limit intake of organ meats

If you live near industrial areas or rely on home-grown produce, consider testing your soil and water for contamination and consult your healthcare provider for further guidance.

31. Strontium

Strontium is a mineral that shares chemical similarities with calcium and has attracted attention for its potential to support bone strength. Some forms of strontium, particularly strontium ranelate, have been studied for their possible benefits in reducing fracture risk and improving bone density in older adults with osteoporosis.

Research, such as that summarized by the National Institutes of Health, shows mixed results. While certain strontium supplements may modestly increase bone mineral density, they are not widely approved for use in the United States due to concerns about potential side effects, such as cardiovascular risks and interference with calcium metabolism. Over-the-counter strontium products are not regulated for safety or efficacy.
Naturally occurring strontium is found in small amounts in foods like grains, leafy greens, and seafood, but these levels are not considered therapeutic.

Leafy green vegetables
Whole grains
Seafood (especially shellfish)

If you are considering strontium supplementation for bone health, consult your healthcare provider first. Medical oversight is essential to prevent adverse effects and ensure safe, evidence-based treatment.

32. Rubidium

Rubidium is a trace element naturally present in many foods, yet its role in human health remains uncertain. Unlike essential minerals such as potassium or magnesium, rubidium is not recognized as necessary for any specific biological function, and there are no established dietary requirements or deficiency syndromes.

According to the National Center for Biotechnology Information, rubidium is found in a variety of plant-based foods, including grains, vegetables, and some fruits. The body absorbs rubidium easily, but most is excreted without apparent effect. There is currently no evidence to suggest that increasing dietary rubidium offers health benefits, nor is there a clear risk from typical food sources.
Supplements containing rubidium are sometimes marketed for mood or energy, but there is little scientific support for these claims, and excessive intake could potentially disrupt electrolyte balance.

Whole grains
Vegetables (asparagus, potatoes)
Fruits (bananas, cherries)

If you have questions about unusual supplements or trace minerals, always consult your healthcare provider before adding them to your routine—especially as you age and your nutrient needs change.

33. Cesium

Cesium is an alkali metal with rare and poorly understood biological effects in humans. It is naturally present in trace amounts in the environment and some foods, but the body does not require cesium for any known physiological processes. Most forms encountered in food and water are non-radioactive (stable) and considered harmless at typical exposure levels.

The Agency for Toxic Substances and Disease Registry notes that the radioactive form, cesium-137, is a byproduct of nuclear reactors and can pose significant health risks if ingested or inhaled, though such exposures are extremely rare. Some alternative health products claim that non-radioactive cesium can benefit pH balance or treat cancer, but these claims lack scientific support and may carry risks such as electrolyte imbalances or cardiac issues.
For older adults, incidental cesium exposure from food is not a concern, but caution is warranted with unregulated supplements.

Vegetables and grains (trace amounts)
Fish and meat (minimal content)

Avoid cesium supplements and be wary of health claims involving trace metals. If you have concerns about environmental exposure or supplements, consult your healthcare provider for guidance.

34. Barium

Barium is best known for its use in medical imaging, particularly in barium swallow tests to visualize the digestive tract. In these procedures, patients ingest a safe, non-toxic form of barium sulfate, which is not absorbed by the body and is passed out unchanged. This medical application is well tolerated and offers valuable diagnostic information.

Dietary exposure to barium comes from trace amounts naturally present in foods and drinking water. According to the Agency for Toxic Substances and Disease Registry, these levels are typically far below those that would cause harm. However, soluble barium compounds (not used in medicine) are toxic and can interfere with muscle and nerve function, particularly in cases of industrial contamination or accidental ingestion.
For most older adults, routine dietary exposure to barium is not a health risk, but caution is warranted in environments with possible contamination.

Leafy vegetables
Root crops (like potatoes and carrots)
Drinking water (trace levels)

If your water source is known to have elevated barium or you’re concerned about environmental exposure, consider water testing and seek advice from your healthcare provider.

35. Thallium (as a contaminant)

Thallium is a highly toxic heavy metal with no beneficial role in human biology. Even at low levels, thallium exposure can damage the nervous system, heart, liver, and kidneys. Symptoms of chronic exposure include fatigue, hair loss, numbness, and digestive issues—concerns that can be especially serious for older adults whose bodies may be less resilient.

According to the Agency for Toxic Substances and Disease Registry, thallium contamination is most often linked to industrial pollution, contaminated drinking water, or certain pesticides. While dietary exposure is rare, produce grown in polluted soil may contain trace amounts. Because early symptoms are nonspecific, thallium poisoning can easily go undetected without proper testing.
Prevention is the best defense against thallium toxicity, especially for vulnerable populations.

Use filtered or tested water if you live near industrial sites
Wash fruits and vegetables thoroughly
Avoid the use of old rodenticides or pesticides
Stay informed about local environmental health advisories

If you suspect thallium exposure or experience unexplained symptoms, consult your healthcare provider for appropriate testing and intervention.

36. Bismuth

Bismuth is best known for its use in over-the-counter stomach remedies such as bismuth subsalicylate, the active ingredient in popular brands like Pepto-Bismol. It is effective in relieving indigestion, nausea, diarrhea, and even some symptoms of ulcers by coating the stomach lining and reducing inflammation. For most people, short-term use is considered safe, and side effects are generally mild.

However, older adults may be more susceptible to side effects, including constipation, darkening of the tongue or stools, and—rarely—neurological symptoms if used in excess or over long periods. According to the Mayo Clinic, serious reactions are uncommon but may include confusion, muscle weakness, or persistent ringing in the ears.
Those with kidney problems or allergies to salicylates (like aspirin) should avoid bismuth-containing products.
