A handful of peanuts (Arachis hypogaea) is a calorie bomb (on average 595 kcal per 100 g), but peanuts on their own certainly do not promote weight gain. They seem to be full of fat (46% of their composition), but they are far from other nuts (sometimes their fat content exceeds 70%), and anyway it does not matter. These nuts are rich in oleic acids, which, instead of being deposited in the form of fat tissue, lower the level of bad cholesterol in the blood and are beneficial to the cardiovascular system.
Peanuts are not found in nature, but only as a cultivated plant. They probably came from Brazil. Today, however, they are mainly cultivated in India, China, Nigeria, and the United States. More resistant varieties are also cultivated in Europe, mainly in Italy and France. They belong to the broad bean family and are characterized by their fruit, the pod.
Why are peanuts called peanuts, if they are not really nuts? Arachis hypogaea is an example of a geocarpic plant. After flowering, the stalks of its flowers (the part of the flower axis that lies below the pistil) elongate, and point to the ground, pushing the seed pod, or our peanuts, underground (they are related to nuts mainly by taste and nutritional value). It matures at a depth of a few centimeters. We include them among the nuts themselves mainly because they resemble them more in taste and nutritional value than other legumes.
Peanuts are sometimes the heroes of crime stories. Sometimes they cause a very severe food allergy, which can lead to anaphylactic shock, so properly used, in the hands of a villain, they can prove to be a deadly weapon. If there is a tendency to allergy in the family, nuts should be introduced into the diet extremely carefully.
From peanuts and nuts to sweeties
It is difficult to find someone who does not like peanuts and nuts. There are so many types of peanuts and nuts that almost everyone will find their favorite. There are peanuts in the shell (inedible, of course), in honey, salt, chocolate, sugar, roasted and candied. There’s peanut butter based on peanuts. Unfortunately, delicious additions to the nuts make them no longer as healthy as the nuts themselves, and their consumption does not go unpunished for our weight, mainly due to the abundance of sugars.
Nuts on their own support the nervous, respiratory, muscular, and circulatory systems. They protect against osteoporosis or atherosclerosis. They take care of the skin. This is due to the valuable nutrients. They contain a lot of protein (over 25%), potassium, magnesium, selenium, phosphorus, youth vitamin E, and niacin (vitamin PP). Peanuts have the most niacin of all nuts. The amino acid arginine contained in peanuts is a valuable building block of human muscles, significantly increasing our training capacity.
