Eat less bracken

Japan and some parts of China have the habit of eating bracken, which contains carcinogenic shikimic acid and quercitrin. This discovery directly led to the decrease of Pteridium aquilinum exported to Japan in previous years. At present, some supermarkets in Hangzhou can also buy cooked bracken or packaged bracken. Eating less should not be a problem, but it is not recommended to eat a lot often.

The International Agency for Research on Cancer also confirmed that safrole, safrole and dihydrosafrole have carcinogenic effects on animals, and they exist in camphor oil, eucalyptus oil, cinnamon and fennel. Chewing betel nut may be related to digestive tract cancer.

Babies with spleen and stomach deficiency and cold should not be eaten.
