Peanuts, in the first place, are not nuts, as many people think. They are a legume and are a strong allergen. They are closer to beans and peas than to hazelnuts and almonds, for example. During the baking process, some of their ingredients are lost, others are changed.

Peanuts have great nutritional value because they are rich in protein, fatty acids and carbohydrates. They also contain many vitamins, especially fat-soluble A and E, which have important antioxidant functions, as well as mineral salts such as magnesium, calcium, selenium and zinc.

All the listed qualities refer to raw peanuts. In the process of baking and salting, these qualities are significantly reduced. Some of the physico-chemical changes that heat treatment causes are:

The pleasant smell obtained during baking is called Mayar's reactionin which proteins and carbohydrates combine. However, this compound is carcinogenic and should not be overdone. Therefore, when using roasted peanuts, it is good to remove the top layer of toasted pod.

The fatty acids contained in peanuts are not resistant to strong heating, especially at temperatures above 180 degrees, such as in the oven. This leads to the formation of molecules with carcinogenic action and the higher the temperature, and the longer the heating time, the greater their number.

Mineral salts lose their biological activity. When heated strongly, they are bound in insoluble salts and cannot be freely absorbed in the intestine.

Another risk posed by eating roasted peanuts is associated with added salt. Intake of large amounts of it has a proven effect on the occurrence of hypertension and cardiovascular disease.

The best advice is to eat unsalted and unroasted peanuts in reasonable quantities - up to 30 g per day, as they contain an average of 65% fat.
