The truth about harmful food combinations (and how to eat safely)

• Science shows most food pairing fears are myths. Prioritize variety, nutrient density and smart cooking for better health. Focus on whole, fresh foods over processed options.
• Cook at lower temps and avoid deep-frying to preserve nutrients.
• Pair meals with antioxidants (e.g., citrus with grilled foods).
• Stay hydrated to flush out toxins like oxalates.
• Don’t fear food combos and enjoy meals mindfully without unnecessary restrictions.

Health warnings about certain food pairings, like grilled fish with pickled vegetables or tomatoes with cucumbers, often circulate online, sparking concerns about potential health risks. But how much of this is based on science, and how much is simply myth?

Nutrition experts emphasize that while some food combinations may have minor interactions, the human body is remarkably resilient. A balanced diet, proper cooking methods and mindful eating habits are far more important than avoiding specific pairings.

Grilled fish and pickled vegetables: A carcinogenic risk?

One common claim is that eating grilled fish with pickled vegetables can lead to the formation of nitrosamines, which are compounds linked to cancer. The theory suggests that amines in fish react with nitrates in pickled foods, potentially forming these harmful substances in the gut.

However, the process is far more complex than a simple food pairing. One’s gut microbiome, overall diet and metabolism all play a role.

While nitrosamines can form under certain conditions, the risk is minimal when considering the bigger picture of a varied, antioxidant-rich diet. (Related: Plant-based diets linked to dramatic drop in cancer risk — but is it really that simple?.)

To reduce the potential risks of eating this food pairing:

• Increase your antioxidant intake – Foods high in vitamin C, like citrus fruits, bell peppers and leafy greens, can help block the conversion of nitrates into harmful compounds inside the body.
• Balance meals with fresh produce – Following a diet rich in whole foods supports gut health and reduces potential negative reactions.

Natto and raw eggs: A threat to biotin?

Another debated combination is natto (fermented soybeans) with raw eggs. Some claim that consuming raw egg whites with natto may lead to biotin deficiency, which can affect hair health. Raw egg whites contain avidin, a protein that binds to biotin, a B vitamin crucial for hair, skin and metabolism.

While occasional consumption is unlikely to cause harm, regularly eating large amounts of raw eggs, especially egg whites, may interfere with biotin absorption over time.

To reduce the potential risks of eating this food pairing:

• Cook eggs thoroughly – Heat deactivates avidin, eliminating the risk of biotin deficiency.
• Limit your raw egg intake – When consuming raw eggs, such as in smoothies or dressings, balance them with biotin-rich foods like nuts, seeds and whole grains.

Spinach and tofu: Do they cause kidney stones?

A long-standing myth suggests that eating spinach with tofu leads to kidney stones due to oxalates in spinach binding with calcium in tofu. However, the opposite may be true; calcium can actually help reduce oxalate absorption by binding to it in the digestive tract, preventing it from reaching the kidneys.

To reduce the potential risks of eating this food pairing:

• Choose calcium-rich tofu – Traditional tofu made with calcium coagulants is more effective at binding oxalates than silken tofu.
• Stay hydrated – Drinking plenty of water helps flush out excess oxalates.
• Avoid excessive vitamin C supplementation – High doses of vitamin C can increase oxalate production in the body.

Tomatoes and cucumbers: Do they cancel out vitamin C?

Some believe that cucumbers contain enzymes that destroy vitamin C in tomatoes. While cucumbers do have ascorbate oxidase, an enzyme that can break down vitamin C in lab settings, the human digestive system is far more complex.

Stomach acid neutralizes most enzymes before they can significantly affect nutrient absorption. Blending tomatoes and cucumbers into a juice may slightly reduce vitamin C levels, but eating them together in a salad poses no real risk.

Rather than fixating on specific food pairings, experts recommend focusing on nutrient density, such as choosing foods that provide the most vitamins, minerals and antioxidants per calorie.

Tips to follow for a healthier diet

Follow these tips for a healthier, more balanced diet:

Prioritize whole foods

Lean meats, wild-caught fish, organic whole grains and fresh fruits and vegetables offer more nutrients than processed alternatives.

Cook at lower temperatures

High-heat cooking (like deep-frying) can degrade nutrients and create harmful compounds in the foods that you eat.

Use natural flavor enhancers

Herbs, spices and naturally sweet vegetables (like carrots and onions) reduce the need for added salt and sugar.

Opt for fresh over processed

Freshly prepared meals provide more nutrients than pre-packaged or reheated foods.

Make small changes

If you eat a lot of fast food or processed food, take small steps to change this over time. Replace unhealthy ingredients with healthy substitutions in your family’s favorite snacks and meals.

Enjoy food without fear

While some food combinations may have minor interactions, the risks are often overstated. A varied, balanced diet rich in whole foods is far more important than avoiding specific pairings.

By focusing on nutrient-dense choices and healthy cooking methods, meals can be both delicious and nourishing without unnecessary restrictions.

The key takeaway? Eat mindfully, cook wisely and enjoy your food without fear.
