The hazelnut tree, a shrub of the Betulaceae family, is known and appreciated for its fruit, an achene called hazelnut. In the kitchen, it is a food of choice. It increases the power of a dish lacking character, or the crunch of a dessert lacking texture. Hazelnuts easily join the ovens and can amply join the medicine cabinet. Extremely rich in vitamin E, they fight against oxidative stress. This oxidative stress accelerates cell aging and increases the risk of cardiovascular disease. Moreover, hazelnuts are among the foods richest in vitamin E. Concerning cardiovascular diseases, the oleic acid (fatty acid predominant in hazelnuts) reinforces all the more this protective power. Hazelnuts are full of many other nutrients, such as vitamins of the B group: B1, B5, B6 and B9. This combination of vitamins helps the body on several levels: strengthens immunity, regulates hormones, improves memory, etc. Let's not forget the minerals and trace elements, such as manganese, copper, iron or magnesium. The latter improve the appearance of hair and nails, help prevent anemia, and so many other benefits that make hazelnuts a healthy superfood. Latin name: Coryfus avellana L. Botanical family: Betulaceae. Part used : Akene.
Because of the energy density of Hazelnuts and their high content of polyunsaturated fatty acid, recommendations for daily consumption are defined. In classic cure or for pleasure, a portion of Hazelnuts is estimated at 15 g per day, which represents about fifteen Hazelnuts per day.
To make the most of their benefits, you can use them :
We advise you to use them during the following meal(s) to take full advantage of their benefits:
You can incorporate them into the following preparations to facilitate their intake:
15g of Hazelnuts contain a significant portion of the Population Nutritional Reference (PNR) of the following nutrients Copper, Manganese and Vitamin E. They also contain, to a lesser extent, Protein, Fiber, Potassium, Iron, Selenium, Zinc, Magnesium, Phosphorus, Vitamin B1, Vitamin B5 and Vitamin B9.
As such, Hazelnuts can complement your healthy and varied diet.
Hazelnuts help to slow down the progression of cardiovascular pathologies and type 2 diabetes, while preventing their complications. Rich in oleic acid, antioxidants and potentially anti-inflammatory, they protect the vascular system from atheromatous plaques. In addition, the high fiber content lowers cholesterol levels and helps the body regulate blood sugar.
Constipation is often synonymous with insufficient fiber intake (see our guide constipation and diet). Adding a few Hazelnuts to your eating habits increases fiber intake, and thus restores digestive transit.
Two nutrients support sperm function and production: zinc and selenium. A deficiency of one of these two nutrients favors oligospermia: an insufficiency of spermatozoa production. Naturally, hazelnuts fight against selenium and zinc deficiencies.
Nutrition modulates the immune response. Indeed, copper, iron and vitamin B6 modulate the functioning of immune cells. Moreover, selenium and zinc participate in the formation of certain white blood cells.
Within a varied and balanced diet, these nutrients provide hazelnuts with immunity benefits.
Hazelnuts stimulate the body. First of all, they bring energy to the body, by the lipids which compose them. Moreover, they offer several micronutrients participating in the energy metabolism (for example, zinc, vitamin B6, copper, magnesium).
Also, they prevent fatigue by contributing to the intake of magnesium, vitamin B6, iron and vitamin B5. These last two, moreover, associated with zinc boost intellectual functions.
This maintenance of general form is also observed on the nervous system. Indeed, potassium and calcium participate in the nervous transmission. However, this general energizing power does not amplify stress. These same micronutrients (magnesium, vitamin B1, B9, B6 and B5) contribute to the normal synthesis of neurotransmitters, which tends to balance the emotions.
Brittle hair or nails can be caused by zinc or selenium deficiencies. Hazelnuts provide these two trace elements, contributing to their strength. In addition, hazelnuts contain copper, which reinforces the intensity of hair color.
The skin also benefits from copper and zinc. Since they act respectively in the protection and in the maintenance of the skin. On the global aspect of the skin, Hazelnuts bring copper and manganese. By their actions on the connective tissue, they give volume to the skin which reduces the appearance of wrinkles.
Bone demineralization increases their fragility and the risk of fractures. Hazelnuts are full of minerals and trace elements that are stored in the bones. This mineralization reinforces the solidity of bones. By the contribution of these minerals, the Hazelnuts take part in the solidity of the bones, to integrate within the framework of a balanced food.
Anemia is multifactorial. Among these factors, we find dietary imbalances. Hazelnuts fight against iron, vitamin B9 and B6 deficiencies: a deficit of one of these nutrients disrupts red blood cell synthesis (see our guides: iron deficiency anemia and diet, macrocytic anemia and diet). Finally, Hazelnuts are rich in copper. Copper promotes the bioavailability of iron.
As part of a healthy lifestyle, the nutrients in hazelnuts help prevent anemia.
The hazelnut tree is well known in France. It belongs to the Betulaceae family. It would be native to the temperate zone of the northern hemisphere, around the Dead Sea. The hazelnut colonizes the edges and forest clearings and appreciates rich soils. This shrub measures 2 to 5 m, its trunk is grayish and its leaves are short-stalked. The flowers are born from January to March, long before the leaves. The hazelnut tree is monoecious: it has male flowers that form yellowish catkins hanging, and female flowers, not very apparent, in a gray bud where only the red stigmas show at their tops.
The hazelnut tree bears fruit at the end of the summer. Its fruit, the Hazelnut, is an achene protected by a tough shell. In 2017, more than one million tons of Hazelnuts were produced worldwide, with Turkey being the main producer (65%), followed by Italy and Azerbaijan. Hazelnut is also appreciated by truffle growers: some hazelnut plants are said to be "mycorrhized", i.e. they are able to produce, under certain conditions, truffles.
Hazelnut taste, hazelnut flavor, hazelnut aroma... So many variations that arouse the interest of our taste buds. They evoke the power of roasted hazelnuts as much as a moment of cocooning subtly accompanied by a hazelnut coffee.
