Fried foods from restaurants, such as French fries, fried chicken, and onion rings, are often loaded with trans fats and sodium—two components that can significantly harm kidney health. Trans fats, commonly found in partially hydrogenated oils used for deep frying, can raise bad cholesterol (LDL) and lower good cholesterol (HDL), increasing the risk of heart disease, which is closely linked to kidney disease. According to the National Kidney Foundation, the sodium content in restaurant fried foods is also alarmingly high, often exceeding 500 mg per serving and contributing to high blood pressure and fluid retention.

Baked, grilled, or roasted alternatives provide similar satisfaction with far lower levels of unhealthy fats and sodium. By choosing these options, you can still enjoy your favorite foods while reducing harm to your kidneys. When eating out, consider splitting fried dishes with others, choosing a side salad or fruit instead of fries, and asking for no added salt. Limiting frequency and portion size is key to minimizing risk.

34. Processed Cheese Spreads

Processed cheese spreads are convenient and creamy, but they often contain high amounts of sodium and a host of preservatives that can be harmful for kidney health. A small serving can deliver more than 400 mg of sodium, and common additives include phosphates and artificial flavorings to enhance shelf life and taste. According to the National Kidney Foundation, excessive sodium and phosphate intake can contribute to elevated blood pressure, fluid retention, and mineral imbalances, all of which put extra strain on the kidneys.

Natural cheeses, such as Swiss or ricotta, generally contain fewer preservatives and, when chosen in low-sodium varieties, can be a safer choice for those managing their kidney health. Even with natural cheeses, it’s important to practice portion control and check nutrition labels for sodium and phosphate content. Alternatively, spread avocado, hummus, or low-sodium cottage cheese on bread or crackers for a creamy texture without the added burden of high sodium and preservatives.

40. French Fries

French fries are a favorite side dish, but their high salt and fat content can be especially problematic for kidney health. A typical restaurant serving can contain over 300 mg of sodium and significant amounts of unhealthy saturated and trans fats due to deep frying. According to the National Kidney Foundation, this combination can raise blood pressure, contribute to fluid retention, and increase the risk of cardiovascular complications—all of which place added strain on the kidneys. Large portion sizes, common in many restaurants, further exacerbate these risks by encouraging overconsumption of both sodium and calories.

For a healthier alternative, try preparing potatoes at home by baking or air-frying them with a light drizzle of olive oil and your favorite herbs or spices. Avoid adding excess salt and instead use flavor boosters like garlic powder, paprika, or rosemary. Opt for smaller portion sizes and pair potatoes with fresh vegetables or a lean protein for a balanced, kidney-friendly meal.

41. Restaurant Pizza

Restaurant pizza is a beloved comfort food, but it is often loaded with sodium, additives, and preservatives that can be particularly challenging for those with kidney concerns. The combination of salty crusts, processed meats like pepperoni or sausage, and generous amounts of cheese can result in a single slice containing over 600 mg of sodium. According to the National Kidney Foundation, excessive sodium intake is linked to increased blood pressure and fluid retention, both of which accelerate kidney damage. Additionally, many pizzas feature phosphate additives in cheese and meat toppings that further strain kidney function.

To enjoy pizza while minimizing the risks, consider customizing your order. Request a thin, whole-wheat crust to reduce sodium and increase fiber, ask for half the usual amount of cheese, and opt for vegetable toppings instead of processed meats. Some restaurants may also offer lower-sodium sauce options or allow you to skip the sauce entirely. If possible, ask for your pizza to be made without added salt or MSG.

42. Sweetened Yogurt

Sweetened and flavored yogurts are widely available and often marketed as healthy choices, but many contain substantial amounts of added sugar—sometimes more than 15 grams per serving. Consuming excess sugar on a regular basis can lead to spikes in blood glucose levels, increasing the risk of obesity and type 2 diabetes, both of which are leading causes of kidney disease. According to the National Kidney Foundation, maintaining stable blood sugar levels is crucial for protecting kidney health and preventing the progression of chronic kidney disease.

Instead of opting for sweetened varieties, choose plain yogurt, which is naturally low in sugar and provides beneficial probiotics, protein, and calcium. You can add natural sweetness and extra nutrients by mixing in fresh fruit such as berries, peaches, or a few slices of banana. For additional flavor, try a sprinkle of cinnamon or a drizzle of honey, but keep added sugars to a minimum.

43. Bottled Iced Tea

Bottled iced tea is a popular beverage, but many commercial varieties are loaded with added sugars and, in some cases, phosphoric acid—an additive also found in colas that can contribute to kidney stone formation. A single bottle can contain over 20 grams of sugar, which can lead to weight gain, spikes in blood sugar, and increased risk of diabetes—all major contributors to declining kidney function. According to the National Kidney Foundation, managing sugar intake is essential for preventing both diabetes and kidney disease.

Phosphoric acid, found in some bottled teas, has been linked to an elevated risk of kidney stones and mineral imbalance. It’s important to read ingredient labels carefully, as these additives are not always obvious. Homemade iced tea is a much healthier choice, as you can control both the type and amount of sweetener used—or skip sweeteners altogether. Brew black, green, or herbal tea at home and chill it for a refreshing, kidney-friendly alternative. Add slices of lemon, fresh mint, or berries for natural flavor without added sugar or harmful chemicals.

45. Flavored Popcorn

Flavored prepackaged popcorn snacks are a popular choice for movie nights and on-the-go munching, but they can be loaded with sodium and artificial flavorings. Many varieties contain over 250 mg of sodium per serving, and ingredients such as artificial cheese, butter flavor, and preservatives can add to the burden on your kidneys. High sodium intake is directly linked to fluid retention and increased blood pressure, which are significant risk factors for kidney disease progression, as outlined by the National Kidney Foundation.

Artificial flavorings and colorings may also present challenges for those with sensitive kidneys, as these additives are not always easily processed and can accumulate over time. In contrast, air-popped popcorn made at home offers a kidney-friendly alternative. It contains minimal sodium and no artificial additives, allowing you to season it with herbs, a light sprinkle of nutritional yeast, or a dash of your favorite spice for flavor without the drawbacks. If you want a bit of salt, add just a pinch to control your intake.

46. Condensed Soups

Condensed soups are a convenient pantry staple, but they often contain extremely high levels of sodium and preservatives. A single serving can have over 800 mg of sodium, and since cans often yield more than one serving, it’s easy to consume well over the recommended daily limit in a single meal. Preservatives such as monosodium glutamate (MSG), artificial colors, and stabilizers are also commonly included, which can further burden the kidneys. According to the National Kidney Foundation, such high sodium intake can accelerate kidney damage, cause fluid retention, and raise blood pressure.

Healthier alternatives include preparing homemade soups using fresh ingredients and low-sodium broths. This allows for full control over sodium and the elimination of unnecessary preservatives. If using condensed soup is unavoidable, try diluting it with extra water and adding unsalted vegetables or cooked whole grains to reduce the sodium concentration per serving. Always check labels for “low sodium” or “no salt added” options when shopping.

47. Bottled Salad Toppings

Bottled salad toppings—such as bacon bits, crispy onions, seasoned croutons, and candied nuts—are often used to add flavor and crunch to salads, but they can be surprisingly high in sodium, sugar, and preservatives. Many of these products contain over 200 mg of sodium per small serving, and candied or glazed varieties are loaded with added sugars. Artificial colors, flavor enhancers, and preservatives are also common, all of which can contribute to kidney strain and overall health concerns. According to the National Kidney Foundation, consuming excess sodium and processed additives increases the risk of fluid retention and high blood pressure, both detrimental to kidney function.

For a healthier approach, opt for natural salad toppings such as fresh or roasted vegetables, unsalted seeds, chopped fresh herbs, or a sprinkle of plain nuts. Sliced avocado, a handful of berries, or a spoonful of fresh salsa can add flavor and nutrition without the hidden sodium and sugar found in processed toppings. Making your own croutons from whole grain bread with just a touch of olive oil and herbs is another kidney-friendly alternative.

48. Sweetened Nut Butters

Commercial nut butters, such as peanut or almond butter, are popular spreads, but many varieties contain added sugars and salt that can negatively impact kidney health. Some brands add several grams of sugar and up to 150 mg of sodium per serving to enhance flavor and shelf life. According to the National Kidney Foundation, excessive sodium contributes to high blood pressure and fluid retention, while high sugar intake can lead to weight gain and increase the risk of diabetes—both strong risk factors for chronic kidney disease.

For a healthier choice, look for natural nut butters with an ingredient list that contains only nuts (and possibly a small amount of oil). These products are free from unnecessary sugars, salt, and preservatives. You can also make your own nut butter at home by blending unsalted, dry-roasted nuts until smooth. If you prefer a touch of sweetness, add a small amount of cinnamon or sliced fruit to your toast instead of using sweetened spreads.

For more information on kidney-friendly spreads and snacks, visit the DaVita Kidney Care snacks recipes. Choosing pure, minimally processed nut butters helps protect kidney health and supports overall wellness.

49. Syrups and Pancake Mixes

Processed pancake mixes and commercial syrups are breakfast staples in many households, but they can be deceptively high in sugar and sodium. Pancake mixes often contain 300-500 mg of sodium per serving, along with added sugars and preservatives to enhance flavor and shelf life. Store-bought syrups, especially imitation maple varieties, are primarily made of high-fructose corn syrup and can deliver up to 20 grams of sugar per two-tablespoon serving. According to the National Kidney Foundation, high sodium and sugar intake increase the risk of high blood pressure, obesity, and diabetes—leading causes of kidney disease.

For a healthier breakfast, consider whole food alternatives like oatmeal made with fresh fruit, whole grain toast with natural nut butter, or homemade pancakes using whole wheat flour and minimal added salt or sugar.
