Hazelnuts are a concentrate of energy, minerals, vitamins and good fats.

Hazelnuts properties and benefits

There are numerous studies that highlight the beneficial properties of hazelnuts, the content in antioxidants protects the body from oxidative stress, and it also seems that they help keep low the level of bad cholesterol, therefore they would help the heart and thanks to the antioxidant properties they carry out a protective action against cancer. Some of the antioxidants, precisely those of the group of phenolic compounds are concentrated mainly in the peel so raw ones would be preferable, but roasted hazelnuts also retain most of their properties.

Nutritional values ​​of hazelnuts

One hundred grams of hazelnuts provide 628 kilocalories, truly an energy snack. Among the vitamins stand out E (the 15 mg contained in 100 grams represent 100% of the daily ration) and Thiamine or B1 whose 0.643 mg represent 56% of the daily ration. Iron, phosphorus, magnesium and manganese are all over 30% of the daily allowance. Hazelnuts are also very rich in coarse but the proportion between monounsaturated and polyunsaturated fats and saturated fats is 93% and 7%. (remember that saturated fats are the most accused of being harmful to health, essentially because due to their chemical structure they are more difficult to metabolize and therefore more easily accumulate in the blood).

History and cultivation

The history of the food use of the stone fruit is very ancient, there are many testimonies that prove that primitive men ate it even before the discovery of agriculture, when they were collectors . The cultivation of hazelnut, on the other hand, was certainly already widespread in Roman times. In Italy and in particular in Piedmont its use in pastry was widespread when cocoa was scarce (which had been introduced in 1600) due to the embargo decreed by Napoleon Bonaparte against English ships. The prohibitive cost to which the caca arrived led to the discovery of the use of hazelnuts in pastry and it was realized that by mixing cocoa and hazelnut a product of excellent quality was obtained. Currently Ferrero absorbs as much as 25% of the world production of hazelnuts for its products. World production is dominated (at least quantitatively) by Turkey with 776,000 tons, Italy in second place with 98,000, followed by Azerbaijan and the United States.

Hazelnuts in the diet

The same goes for all dried fruit, in small quantities they can be an energetic and healthy snack. Don't overdo it for the calorie intake issue, obviously it also depends on how much you burn. As a snack for athletes or for those who want to gain weight but also to recharge their energy, they are perfect not only for calories but because as we have seen they are rich in mineral salts, for example we have mentioned magnesium which is the energy source of cells and which it is put in supplements not by chance. The good fatty acids can also make them useful as antioxidants and for the health of the arteries, a small amount at breakfast can allow you to dispose of the calories during the day and ensure the benefits.

Plant and fruit

For hazelnut we mean the fruit of all trees of the genus Corylus, which includes both deciduous trees (which lose their leaves in winter) and large bushes, the family of belonging is that of the Betulaceae. The common hazel is the Corylus avellana species. Although all the fruits of the hazelnut species are commercially edible, the only relevant one is Corylus avellana, some of the other species are used for ornamental purposes. In cultivation, the stone reaches heights between 2 and 4 meters, but if left free it can reach eight. It sheds its large leaves in winter. The inflorescences are unisexual of male or female type, therefore the plant for fertilization needs to be pollinated. When the fruit is ripe, the hazelnut, which is wrapped in bracts (modified leaves) is released and falls.
