6. Joint pain

Many millions of people suffer from joint conditions such as arthritis, stiffness, pain, swelling and reduced mobility. The underlying cause of these symptoms is inflammation, which is when the body’s immune system starts affecting the joints. The pain and swelling that occur as a result of this inflammation can cause severe debilitation.

Typical symptoms include pain during movement, stiffness or swelling of the joints and persistent aching in the joints such as the shoulders, back, knees, hips, wrists or ankles. Many health care practitioners  recommend treatment that includes anti-inflammatory medications and analgesics to combat the pain. The trouble is, medications have side-effects, and in the case of these meds, you might suffer diarrhea, increased blood pressure and a reduced ability to fight off infections.

After ruling out underlying medical conditions with your doctor, try taking a closer look at what you eat. Because we all react differently to the various foods and beverages we consume, just about any ingredient could be causing or contributing to your joint pain.

Once again, documenting what you eat and drink can allow you to work out what might be contributing to your symptoms. Then, it becomes a matter of eliminating the offending food or drink.

7. Hives

If you develop hives shortly after eating or drinking, you might be having a life-threatening allergic reaction to what you have consumed. In this instance, you need emergency medical treatment. Hives and other symptoms such as difficulty breathing, an itchy throat, swollen tongue or lips, swollen throat, or a rash around the mouth are manifestations of an anaphylactic reaction. This reaction is indicative of a severe allergy, and urgent medical treatment is required to prevent a possible fatality.

The symptoms of a food allergy vary from food to food. An allergy to foods such as fish, especially shellfish, and nuts can lead to an anaphylactic reaction within minutes of consuming the offending ingredient.

Hives on the tongue usually indicate a severe reaction, but can also be caused by intolerance to vegetables from the nightshade family, including red peppers, eggplants, white potatoes and tomatoes.

If you develop hives on your tongue without any of the other symptoms of anaphylactic shock, make a note of what you have eaten. You might have a food intolerance you weren’t aware of. If it happens more than once without the development of the other anaphylactic symptoms, you should probably eliminate that food.

8. Diarrhea and constipation

There’s been a lot of talk about gluten and whether we should be eating it, but some people are definitely gluten intolerant. The most severe form of gluten intolerance is known as celiac disease, an autoimmune disorder in which the body attacks the small intestine when gluten has been consumed.

Gluten is a protein found in wheat, rye, barley and some oats. Many manufacturers are producing gluten-free products these days in response to what seems to be a growing problem. Celiac disease causes many health problems, including diarrhea and constipation, as well as headaches and migraines, skin rashes, chronic fatigue or weight loss, oily stool (steatorrhea) and the inability to properly absorb vital nutrients such as vitamins B12 and D, as well as iron.

But you don’t have to suffer from celiac disease to be sensitive to gluten. In non-celiac gluten sensitivity or intolerance, the body doesn’t react well to gluten, but the autoimmune symptoms of celiac disease are not present.

Studies have found that 50% of people who are gluten sensitive experience diarrhea, while 25% suffer from constipation. But diarrhea and constipation can be caused by a multitude of factors, not just food intolerance.

Arthritis. Image via Shutterstock

9. Arthritis

There are more than 100 different kinds of arthritis and diseases related to arthritis. The most common types of arthritis are osteoarthritis and rheumatoid, both of which involve inflammation of one or more joints in the body. The significant symptoms of arthritis are stiffness and joint pain, which usually worsen with age.

In osteoarthritis, the cartilage that cushions the joints between bones breaks down. In rheumatoid arthritis, the lining of the joints (synovium) is attacked by the body’s immune system, making it an autoimmune disease. Other kinds of arthritis might be caused by diseases like lupus or psoriasis, or by the presence of uric acid crystals in the joints, or by infection.

Different kinds of arthritis require different kinds of treatment to allow the sufferer to live a better life with fewer symptoms. Osteoarthritis and rheumatoid arthritis cause damage to the joints in different ways and have different causes.

It is interesting to note that most scientific studies have found that between 30% and 40% of people with rheumatoid arthritis can improve their condition substantially if they use an elimination diet to identify foods that precipitate symptoms and avoiding these foods.

Gastroesophageal reflux disease : GERD. Image via Shutterstock

10. Acid reflux & heartburn

If you often suffer from heartburn or acid reflux after eating or drinking, you might have an undiagnosed food intolerance. Acid reflux is when the naturally-occurring acids in your stomach, as well as other stomach contents, move up into the esophagus. They pass through the lower esophageal sphincter (LES), a ring of muscle where the esophagus and the stomach meet. Usually, the LES opens to allow food into the stomach when you swallow. It then closes to stop the food from coming back up. However, if the LES is damaged or weak, it might not close completely. That’s when stomach contents and acids can move back up into the esophagus. This is acid reflux, which is estimated to affect around 20 percent of Americans.

Gastroesophageal reflux disease, or GERD, is a severe, chronic form of acid reflux, and can lead to serious health problems if untreated. The symptoms of acid reflux differ in form and severity. They include experiencing symptoms after a fatty or spicy meal, after a heavy meal, or when lying down or bending over. Heartburn is the most common symptom of acid reflux. Heartburn is a painful burning in your chest caused by stomach acids leaking from the stomach into the esophagus.

11. A runny nose

If you have a runny nose after eating, it could be caused by many factors. The medical term for a runny nose is rhinitis, and it can be allergic or non-allergic. If you have a food allergy, your nose might run within two hours of eating a particular ingredient, and will probably be accompanied by other symptoms.

As we said earlier, anaphylactic symptoms require urgent treatment. However, if your nose runs within a couple of hours of eating and you have other, less severe symptoms, your runny nose might be a sign of food intolerance. The reason the nose runs is that it is attempting to cleanse itself.

If a runny nose plagues you after eating, try keeping a food journal in which you note everything you eat and drink, as well as how you feel and any symptoms you experience. This way, you might be able to narrow down or find out exactly what foods or beverages if nay are triggering your symptoms. Then, eliminating the food will alleviate the symptoms. In the meantime, your doctor might prescribe medication to deal with your runny nose and any an accompanying cough or sneezing symptoms.

Acne and rosacea. Image via Shutterstock

12. Acne and rosacea

Although food allergies and food intolerances are not the same, if you are intolerant to some food or beverage, you should avoid it. Food allergies can show up in various skin conditions, including rashes, hives, eczema, rosacea, acne, puffiness and itchiness. This is because the immune system is overreacting to a particular allergen that the body views as harmful, even if it isn’t.

The immune system summons disease fighters called immunoglobulin E (IgE) antibodies. When you eat a portion of food that contains that particular protein, the body releases IgE antibodies and other chemicals, including histamine in an attempt to get rid of the “invader” protein.

Image via Shutterstock

Histamine is a powerful substance that causes allergic symptoms in various parts of the body, depending on where in the body the histamine is released. If released in the skin, you could experience one or more of the issues mentioned above.

If you have any of these skin problems, you might be suffering from a food allergy or an intolerance to a particular ingredient. Keeping a food diary that matches symptoms to foods consumed will allow you to narrow down the ingredients that might cause your symptoms.

13. General malaise

If you’re generally feeling under the weather, the cause might be a food intolerance. If you are regularly consuming foods or beverages that contain ingredients to which your body is oversensitive, your body is being put under strain. Rather than any specific symptom, you might just be feeling off-color. If you’re sure you’re leading a healthy lifestyle with a balanced diet, adequate water and sleep, and reasonable levels of exercise, yet still feel generally unwell, it’s time to visit your doctor.

Your doctor might want to do tests to discover any underlying conditions that might not be immediately apparent. But sometimes, no problems can be found, and you’re left still feeling off-color. That’s when taking a closer look at your diet might be the next logical step.

Image via Shutterstock

The saying goes that we are what we eat. And we might not be feeling all that well if we eat certain things. Start by keeping a food diary. Every day, write down everything you drink and eat and any symptoms you have. Then, when you find out what foods you are sensitive to, you can eliminate them from your diet.

14. Mouth ulcers

Do mouth ulcers plague you? Also known as canker sores, mouth ulcers are usually small, painful lesions in the mouth or at the base of the gums. They can make everyday activities like eating, drinking and talking uncomfortable. They aren’t contagious and usually go away within a week or two.

If you get a large sore that doesn’t heal or is very painful, consult your doctor. While no definitive cause for mouth ulcers has been found, certain triggers and factors have been identified. These include food sensitivities, especially to acidic foods like citrus fruits, pineapple and strawberries, as well as other foods like coffee and chocolate.

Some mouthwash and toothpaste that contain sodium lauryl sulfate can cause canker sores, as can a lack of nutrients like vitamin B12, folate, iron and zinc. Hormonal changes that accompany menstruation can also cause mouth ulcers, as can various viral, fungal and bacterial infections.

Mouth ulcers can sometimes be signs of severe conditions, including diabetes, Bechet’s disease, HIV/AIDS, celiac disease, and inflammatory bowel disease. These require medical treatment. See your doctor if you have large ulcers, recurring ulcers, ulcers that last more than three weeks, painless ulcers, uncontrollable pain, severe problems with eating and drinking and fever or diarrhea when the ulcers appear.

Respiratory problem. Image via Shutterstock

15. Respiratory problems

If you experience a runny nose (rhinitis) or sinusitis on a recurring basis due to food intolerance, it might be accompanied by respiratory problems such as shortness of breath. Although rhinitis can be treated with various medications, many of these come with undesirable side-effects and doesn’t get to the cause of the issue.

If you are having problems breathing without an apparent reason such as the common cold or flu, visit your healthcare provider to rule out any underlying medical conditions that might be causing your symptoms.

If you keep getting rhinitis or sinusitis that is causing shortness of breath, it’s time to take a look at your eating habits. This is where following an elimination diet under the guidance of your doctor can be highly beneficial in relieving symptoms. For example, one study showed that eliminating “trigger” foods alleviated sinusitis in 89% of participants, and asthma and rhinitis in 72% of participants.

To follow an elimination diet, it’s necessary to keep a food journal in which you record everything you consume and what symptoms you experience. If you have a food intolerance, a link will show between an ingredient and one or more symptoms.

Anxiety and depression. Image via Shutterstock

16. Anxiety and depression

Millions of people around the world suffer from anxiety or depression, and the causes vary from situational to chemical. The role of diet on our health cannot be underestimated. In recent times, science has been paying closer attention to the relationship between the brain and the digestive system.

It turns out that the digestive system produces 90% of the serotonin produced by the body. Serotonin is a hormone that makes us feel happy, and many anti-depressant medications focus on restoring the balance of serotonin in the brain. But what about the role of the gut?

Image via Shutterstock

Another fascinating finding is that the brain and the gut contain 30 identical neurotransmitters. These chemicals, of which serotonin is just one example, carry messages around the brain and the body. They are also responsible for how we feel. It follows, then, that if we have an unhappy digestive system, we’re likely to feel depressed. Interestingly, scientific studies have found gastrointestinal inflammation in a large number of people suffering from depression.

This inflammation is one of the main overarching symptoms of food intolerance, which can be linked to depression. That relationship goes both ways. A depressed mind influences the gut and vice versa.

Irritable bowel syndrome. Image via Shutterstock

17. Irritable bowel syndrome

Although people with Irritable Bowel Syndrome (IBS) are sensitive to food, few people with this disorder have a food allergy. Between 3-20 percent of people in the U.S. suffer from IBS symptoms, women more than men.

Some people experience minor symptoms, but others’ symptoms are so severe that they disrupt daily life. Also known as spastic colon, irritable colon, mucous colitis and spastic colitis, IBS is not the same as inflammatory bowel disease and is not related to other conditions of the bowel.

IBS is a cluster of symptoms that usually occur together, and which vary in duration and severity from person to person. IBS symptoms include diarrhea, constipation (often alternating), bloating, gas, abdominal pain, cramping and discomfort.

Food intolerances linked to IBS include dairy foods, beans and pulses, indigestible sugars, fried foods, processed foods and cabbage. Sometimes, chamomile, peppermint and ginger can help to reduce symptoms.

Food Aversion. Image via Shutterstock

18. Food aversion

People with an aversion to a particular food or drink might feel ill if they think about consuming the substance and might find it virtually impossible to take a mouthful of it as they believe it will make them sick. But the problem is psychological. The person believes that a particular food will make them ill, causing them to develop actual physical symptoms.

Food aversion. Image via Shutterstock

Food aversion is a psychological food intolerance wherein a negative physical reaction is associated with ingesting food. A psychological food intolerance has symptoms similar to real food intolerance, but the reactions are psychosomatic.

Some people with a food aversion might develop hyperventilation syndrome in response to food to the extent that they lose consciousness.

19. Milk and yogurt upset your stomach

If you experience gastrointestinal or other symptoms after consuming milk or yogurt, you might be lactose intolerant. Lactose is the natural sugar in milk. To digest lactose, we require adequate quantities of the enzyme lactase. The trouble is, early humans lacked this enzyme and were unable to digest milk products.

An estimated 65% of humans struggle to digest lactose and milk products after infancy. This rate of intolerance is much higher in some areas of the world, with the rate as high as 90% in people of East Asian descent.

Symptoms differ in severity from person to person, but lactose intolerance usually manifests as gastrointestinal symptoms that are similar to those of IBS, namely cramping gas, bloating, diarrhea or constipation, and abdominal pain. The most obvious solution is to avoid milk products, but read product labels carefully as milk sneaks into thousands of products.

Hypothyroidism. Image via Shutterstock

20. Underactive thyroid (hypothyroidism)

The thyroid gland is a vital hormone gland. It is butterfly-shaped and lies at the front of the neck. The thyroid gland is essential role in human development, bodily growth and metabolism. It helps regulate many of the body’s vital functions by releasing a steady stream of hormones into the bloodstream. Thyroid hormones are wholly or partially responsible for body temperature, moods and energy levels.

When your thyroid is not producing enough hormones, you develop hypothyroidism. This leads to various symptoms, such as sleeping problems, fatigue, depression, cold sensitivity, and constipation. Sometimes, food intolerances can play a role in an underactive thyroid.

Finding out if you have a food intolerance if you have hypothyroidism can be severe because symptoms can be similar. For example, if you have a gluten intolerance, you might experience bloating, fatigue and depression, which mimic hypothyroidism.

21. Caffeine sends your system into overdrive

We all know caffeine is a stimulant. That’s probably why it’s one of the world’s most popular beverages. But caffeine is not everybody’s cup of tea.

Being caffeine intolerant is possible. How your body reacts to caffeine differs from person to person, and one of the primary reasons for that comes down to your genes.

Image via Shutterstock

Doctors offer genetic testing for caffeine sensitivity. If, for example, your body metabolizes caffeine slowly, you might experience significant discomfort if you drink a strong cup of coffee. Symptoms can include sweating, increase in blood pressure, and digestive distress.

With regular consumption, there is an increased risk of heart disease. So, if your system goes into overdrive if you consume something with caffeine in it, try choosing herbal teas that are naturally caffeine-free.

22.You always feel exhausted in spite of sleeping well

If you are still exhausted, mentally/emotionally and physically, you might suffer from chronic fatigue syndrome. This disorder involves severe, long-term fatigue that negatively impacts on the person’s ability to function in everyday life. Between 1-4 million Americans suffer from the condition. Less than 20% are diagnosed. The trouble is that the scientific community does not fully understand the causes of chronic fatigue syndrome.

Chronic Fatigue Syndrome. Image via Shutterstock

That said, food intolerance has been a suspect for a long time. Some believe food intolerance is a trigger for the disorder. It can combine with other triggers such as genetics, stress and inflammation.

There is no list of specific foods related to chronic fatigue syndrome. And to make matters worse, foods that might give you a temporary “‘lift” might be the very ones that cause the fatigue a day later.

23. You run to the bathroom all day

If you avoid certain events or places because the bathrooms aren’t great, you might be suffering from food intolerance. This kind of thinking is relatively common in someone with strong food intolerance. The first symptom to strike after ingesting the offending ingredient comes in the form of digestive distress.

Rushing to the bathroom several times a day is common in people with food intolerances. Symptoms include bloating and gas, diarrhea, abdominal pain, all symptoms associated with irritable bowel syndrome (IBS).

Image via Shutterstock

One of the culprits responsible for this condition is FODMAP foods. FODMAP is short for Fermentable oligo-, di-, mono-saccharides and polyols. This is a collection of short-chain carbohydrate molecules that the body cannot absorb well.

If you have gastrointestinal symptoms, FODMAPs can bring on diarrhea or constipation, wind, bloating and abdominal pain. A low FODMAP diet has proved successful in relieving gastrointestinal symptoms in a majority of IBS sufferers.

Image via Shutterstock

24. Enzyme deficiencies

If we don’t have the right digestive enzymes in the right quantities, we might develop a food intolerance. After we have chewed our food, digestive enzymes break down the larger food particles into smaller molecules. This process begins taking place in the mouth while we are chewing our food. It then continues in the stomach, where stomach acids and enzymes act upon the smaller pieces of food.

Image via Shutterstock

It continues in the small intestine, where tiny pieces of food pass through the gut lining and enter the bloodstream. The food we eat contains three macro-nutrients: proteins, carbohydrates and fats. Milk contains all three. The enzyme lactase is not present in people who are lactose intolerant, so milk sugars (lactose) can’t be absorbed. This produces gas, cramping, diarrhea, constipation and bloating.

Image via Shutterstock

25. Itchy skin

A familiar sensation many people feel when they eat food they’re intolerant to is itchy skin. This can also be a sign of many other conditions, such as eczema or hormonal changes. To differentiate different types of itches, you have to check how does your skin respond to scratching.

If the itch feels like it’s under the skin, food intolerance might be the cause of your problems. The important thing is to stay calm and not panic.

Image via Shutterstock

Be sure to alert your doctor if you can’t get rid of the itch. Before you do anything, it’s important to know that scratching too much won’t make matters any more comfortable. Control yourself and be sure not to injure yourself.

A mild or cold shower can reinvigorate you and allow other sensations to overshadow the itching feeling. Wait for a day or two and think about what could have possibly caused the itch. Experiment and conclude.
