Foods You Should Avoid Unless Your Genes Can Handle Them

Throughout history, various ethnic groups have developed unique genetic adaptations that allow them to thrive on specific diets. These adaptations are often a result of generations of evolution and cultural practices that have shaped their dietary preferences and tolerances. Let’s explore 20 ancestral foods that only certain ethnicities can truly enjoy, thanks to their unique genetic makeup, and understand what might happen if others try to eat these foods.

1. Dairy Products (Northern Europeans)

Northern Europeans have developed lactose tolerance, allowing them to digest dairy products easily. However, many people of East Asian, West African, and Native American descent lack the enzyme lactase needed to process lactose, leading to bloating, diarrhea, and stomach cramps if they consume dairy. The absence of lactase means their bodies can’t break down lactose, resulting in discomfort and digestive issues.

2. High-Fat Marine Diets (Inuit)

The Inuit have adapted to a high-fat, high-protein diet due to their cold climate. Those not adapted to this diet may experience digestive issues, high cholesterol, and difficulty processing the high levels of omega-3 fatty acids found in their staple foods like fish and seal meat. These high-fat foods can be tough on the digestive systems of people unaccustomed to such diets, potentially leading to nausea and discomfort.

3. Sorghum and Millet (Africans)

African diets often include grains like sorghum and millet. These can cause gastrointestinal discomfort and nutrient absorption issues for those unaccustomed to them. The high fiber content and specific proteins in these grains can be hard for others to digest, leading to bloating and stomach cramps.

4. Soy and Rice (East Asians)

East Asian diets are rich in rice and soy. People not accustomed to high soy consumption might have trouble digesting it, leading to bloating and gas. Additionally, some individuals may have rice allergies or sensitivities, which can cause digestive issues and allergic reactions.

5. High-Carbohydrate Diets (Pacific Islanders)

Pacific Islanders traditionally consume high-carbohydrate diets. For those not genetically adapted to process such large amounts of carbs efficiently, this can lead to rapid weight gain and metabolic issues. The high carbohydrate intake can overwhelm the body’s ability to manage blood sugar levels, causing spikes and crashes.

6. Cassava (South Americans)

Cassava, a staple in South American diets, contains cyanogenic glycosides, which can be toxic if not properly prepared. Those unfamiliar with its preparation might suffer from cyanide poisoning, leading to severe health issues such as headaches, dizziness, and even fatal outcomes in extreme cases.

7. Fermented Foods (Eastern Europeans)

Fermented foods like sauerkraut and kefir are common in Eastern European diets and are rich in probiotics. However, consuming large amounts of these can upset the digestive system of those not used to them, leading to bloating, gas, and discomfort due to the high levels of beneficial bacteria.

8. Spicy Foods (South Asians)

South Asian diets are known for their spicy foods. The capsaicin in these dishes can cause digestive distress, heartburn, and even ulcers in people not accustomed to it. The intense heat can irritate the digestive tract, leading to discomfort and pain.

9. Marine-Based Diets (Coastal Mediterraneans)

Coastal Mediterranean populations thrive on marine diets. A diet high in seafood can cause digestive issues and shellfish allergies in those not typically consuming marine-based diets. The rich seafood diet can be difficult to digest and may cause allergic reactions in sensitive individuals.

10. Game Meat (Indigenous North Americans)

Indigenous North American diets often include game meat, which can be very lean and tough. Consuming these meats can cause digestive issues and potentially carry parasites or diseases unfamiliar to non-indigenous populations, leading to health risks.

11. Fermented Starches (West Africans)

West African diets often feature fermented starches like fufu. These can cause gastrointestinal discomfort for those not accustomed to fermentation byproducts. The unique fermentation process can produce compounds that are hard for others to digest, causing bloating and gas.

12. Blood Products (Scandinavians)

Scandinavian diets include blood sausage. Consuming blood products can cause nausea and digestive issues for those unaccustomed to it. The high iron content and unique texture can be off-putting and difficult to process for many.

13. Maize (Native Americans)

Native American diets heavily feature maize (corn). Non-adapted individuals may struggle with maize’s high starch content, leading to digestive issues like bloating and discomfort. The specific proteins in maize can also cause sensitivities in some people.

14. Raw Fish (Japanese)

Japanese diets often include raw fish in dishes like sushi. Those not used to consuming raw fish may face digestive issues or risk of parasitic infections, as their bodies are not adapted to handle the potential bacteria and parasites found in raw seafood.

15. Fermented Dairy (Mongolians)

Mongolian diets include fermented dairy products like airag. Those not accustomed to fermented dairy can experience digestive discomfort, gas, and bloating due to the high levels of probiotics and fermentation byproducts.

16. Hot Peppers (Mexicans)

Mexican diets frequently include hot peppers. Capsaicin in hot peppers can cause severe digestive discomfort, heartburn, and even ulcers in people not used to spicy foods, making it a challenging dietary addition for many.

17. Fermented Soybeans (Koreans)

Korean diets feature fermented soybeans in dishes like natto. Fermented soybeans have a strong flavor and unique texture that can be difficult to digest, leading to bloating and gas for those not accustomed to them.

18. Cactus (Mexicans)

Cactus, particularly prickly pear, is a common food in Mexican diets. Consuming cactus can cause digestive issues like bloating and gas in people not used to it, due to its high fiber content and unique compounds.

19. Seaweed (Japanese and Koreans)

Japanese and Korean diets often include seaweed. While nutritious, seaweed can cause digestive discomfort and iodine imbalances in those not used to it. The high mineral content can be tough on the digestive system of those unaccustomed to it.

20. Bitter Melon (South Asians)

Bitter melon is common in South Asian diets. The bitterness can be off-putting, and it may cause digestive distress and lower blood sugar levels too much in those not accustomed to it.
