Unsaturated fatty acids in peanuts will be oxidized to saturated fatty acids by heating; Heating can also lead to the reduction of vitamins, so cooked peanuts reduce the nutritional value to some extent.

People usually like to eat boiled peanuts. In fact, eating peanuts raw has many unexpected benefits. First of all, eating raw peanuts has a prominent advantage of nourishing the stomach, because peanuts are rich in unsaturated fatty acids, cholesterol-free, and dietary fiber, which is a natural low-sodium food. Eating a proper amount of raw peanuts (no more than 50 grams) every day is good for nourishing the stomach.

When eating raw peanuts, they are usually eaten with red clothes. Peanut red clothes are a good thing. Female friends, especially those during menstruation, pregnancy, postpartum and lactation, should eat more, which is conducive to nourishing blood and enriching blood. At the same time, peanut red also has the effect of growing hair and blackening hair. Regular consumption can make hair darker and brighter.

But not everyone eats raw 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 blood stasis. In addition, because peanuts contain a lot of oil and need to consume more bile to help digestion, people who have undergone cholecystectomy or gallbladder disease should not eat more peanuts.
