It is possible that eating tempeh may increase the incidence of cancer, but eating tempeh does not necessarily lead to the development of cancer. Cancer is a major disease that poses a serious threat to the health of the population, and it is caused by a variety of factors, such as physical factors such as radiation, chemical factors such as cancer-causing compounds, and hereditary factors. Studies have shown that long-term consumption of preserved foods may lead to an increase in the incidence of cancer due to the production of nitrite compounds. Tempeh is a kind of food that has been pickled, and if you consume this kind of food for a long time and in large quantities, your body will consume too much nitrite, which is carcinogenic, and it may lead to an increase in the incidence of cancer. It is worth noting that carcinogens are not necessarily carcinogenic, the probability of cancer increases with intake, so for health reasons, it is recommended to reduce the intake of pickled foods.
