Type of diet discovered that protects against cancer development

Vegetarian diets can significantly reduce the risk of developing certain types of cancer, according to Nuria Dianova, a first-category dietitian and gastroenterologist.

As reported by TUT.AZ with reference to "Gazeta.Ru", a study published in August 2025 revealed a convincing link between various types of vegetarianism and reduced cancer risks. The results showed that young vegans demonstrate lower rates of breast and prostate cancer. Among the older generation who prefer pescatarian diets, there is a noticeable decrease in cases of colorectal cancer and breast cancer.

The study also found that vegans and lacto-ovo-vegetarians less frequently face oncological diseases related to lymphoproliferative processes and lymphoid leukemias. Particularly noteworthy is that all groups of vegetarianism adherents, especially lacto-ovo-vegetarians, demonstrate a reduced risk of developing stomach carcinoma. According to the specialist, these data indicate the existence of mechanisms that contribute to reducing the frequency of certain types of cancer, primarily those associated with the gastrointestinal tract.

Dianova specifically noted the danger of processed meat as a significant risk factor for developing stomach cancer and colorectal cancer. During the process of smoking, salting, and adding preservatives and nitrites to meat products, carcinogenic compounds are formed that damage the DNA of intestinal cells, creating a favorable environment for tumor development.

According to the expert, the predominance of plant food in the daily diet can act as a powerful preventive factor against the two most common types of cancer – breast cancer and colorectal cancer. Reducing the consumption of red and processed meat, replacing it with fish, eggs and dairy products, including plant proteins along with regular consumption of vegetables, fruits, greens and berries can significantly reduce oncological risks.
