Fried and fatty meat and pasta should not be eaten. Don’t eat crabs, crucian carp, scallops, eels, rooster, pig’s head meat, pig’s jowl and other “hairy things”. Although some people think that there is no scientific basis for these foods, from the fact that cancer symptoms often worsen or spread after patients eat them, not eating them is still beneficial to the treatment. As for other foods, as long as they are easy to digest and absorb and rich in nutrition, they can be eaten. Some people classify tofu and eggs as “hairy food”, which is not true. Soybean products, eggs and dairy products are the nutrients needed for consumptive diseases, which will not aggravate the development of tumors and should be consumed in moderation every day.
