1. Moldy peanuts are rich in super carcinogen aflatoxin, which can withstand high temperature above 280 degrees, and the highest temperature of pressure cooker is only 180 degrees. It is impossible to tell whether they are moldy or not after boiling.

2. Because boiled peanuts should be eaten with the red inside, it is not suitable for patients with falls and injuries to eat peanuts. Even the best food is not suitable for everyone to eat peanuts. It is not "excusable" for middle-aged and elderly people to eat peanuts. For example, some patients with traumatic injuries should not eat it. Peanut red coat can stop bleeding and promote blood coagulation. People with traumatic injuries and blood stasis eat too much, which will make blood stasis difficult to disperse and aggravate it. Some middle-aged and elderly people have poor digestive function and "loose stool due to spleen deficiency", so they should not eat peanuts, because peanuts are rich in oil and have a laxative effect, which will aggravate diarrhea. In addition, because peanuts contain a lot of oil and need to consume more bile to help digestion, middle-aged and elderly people who have undergone cholecystectomy or have serious gallbladder diseases should not eat more peanuts.
