Globalna produkcja orzeszków ziemnych sięga milionów ton rocznie, przy czym produkt ten występuje w różnorodnych formach – od pełnych nasion, przez wyroby cukiernicze, aż po masło orzechowe, olej czy składniki wysokobiałkowych preparatów żywieniowych. Ze względu na niską cenę w przeliczeniu na zawartość białka, stanowią one atrakcyjny surowiec dla przemysłu spożywczego, który nieustannie poszerza zakres ich aplikacji. Jednak czy ich regularne spożywanie przekłada się na konkretne korzyści zdrowotne? Czy istnieją naukowo udokumentowane powody, aby włączać je do codziennej diety?
Peanuts and nuts
Nuts, despite their name, are not nuts at all. They are a species belonging to the legume family. They come from South America from Brazil and Peru, but are often grown in tropical and subtropical countries. Nuts are a good source of protein, fat and fiber. They contain mainly mono- and polyunsaturated fatty acids.
Peanuts properties
Nuts are a source of mineral ingredients. They are rich in potassium, magnesium, calcium, phosphorus, iron, copper, zinc [2]. The mono and polyunsaturated fatty acids found in nuts lower LDL cholesterol levels and reduce the concentration of lipids in blood serum. The nuts are high in: vitamin E, folic acid, dietary fiber, phenolic compounds, and resveratrol [1].
How do peanuts grow?
As we already know, peanuts are not considered nuts because they belong to the family of botanical plants, namely, nuts. This is due, among other things, to the way they are grown. The pistachios grow and mature underground, hence the name of the nuts, because when the flower stalk blooms, it stretches and then goes downward, pushing the stems into the ground. The nuts mature to a depth of about 5 to 8 cm. When they mature, they don't break up into pieces or fall apart.
Are peanuts healthy?
However, in addition to a number of mineral ingredients (e.g. starch oil), starch also contains fiber, phenolic compounds, or vitamins. It has been shown that eating starches can help control body weight and also prevent Alzheimer's disease and heart disease, and inhibits the growth of cancer cells.[1] However, eating both starch and starch-based products (i.e. potato oil) in a nutritious diet can also have a significant effect on the body's lipid metabolism. Studies of starch products have shown that dietary allergies to fat or fat-soluble products can also increase the fat content of fat in a single diet or dietary product after eating HD foods, reduce the fat burden of the body over the entire diet.
