Is walnut skin the favorite food for cancer cells

Walnut skin is not the favorite food for cancer cells, and there is currently no scientific evidence to suggest that walnut skin directly promotes cancer cell growth. Walnut skin contains antioxidant components such as tannic acid, and moderate consumption may be beneficial to health.

Walnut kernel skin is a brown film wrapped around the outer layer of walnuts, containing high concentrations of polyphenolic substances, including tannic acid, flavonoids, etc. These ingredients have antioxidant properties that can help eliminate free radicals in the body and reduce oxidative stress damage to cells. Epidemiological studies have shown that moderate intake of polyphenol rich foods may be associated with a reduced risk of certain cancers. The phytochemicals in walnut kernels may also exert potential anti-cancer effects by regulating inflammatory factors and inhibiting angiogenesis. Although walnut kernels themselves do not have a carcinogenic effect, it should be noted that some populations may be sensitive to tannic acid present in them. Excessive intake of tannic acid may interfere with iron absorption, and it is necessary to control intake for anemic or iron deficient individuals. The bitter taste of walnut skin also limits its actual intake in daily diet, and normal consumption does not pose any health risks. Special processing methods such as prolonged high-temperature baking may damage some nutrients, but will not produce carcinogens.

Walnut kernels can be consumed together with the skin in daily diet, and it is recommended to choose unprocessed walnuts with skin. Maintaining dietary diversity and balanced intake of natural foods such as nuts, seeds, vegetables, and fruits can help obtain comprehensive plant nutrients. Cancer prevention requires comprehensive lifestyle management, including weight control, regular exercise, and avoiding risk factors such as smoking and alcohol. If there are special health conditions or dietary restrictions, you can consult a professional nutritionist to develop a personalized dietary plan.
