Hazelnuts are full of nutrients. A study by Oregon State University, published in December 2018 in the Journal of Nutrition, shows: regular consumption of nuts increases the level of magnesium and vitamin E.

60 grams of hazelnuts daily

32 subjects aged 55 and over ate 60 grams of hazelnuts every day for four months. The scientists then measured their vitamin and mineral levels. Conclusion: Vitamin E and magnesium increased significantly.

Magnesium deficiency

A magnesium deficiency is uncomfortable. The muscles twitch, the bowel revolves alternately with diarrhea and constipation. The heart is racing, the head is aching. Those affected become dizzy, they feel tired and at the same time are driven internally.

Vitamin deficiency

Vitamin E deficiency is also serious. It usually begins with unspecific symptoms: the concentration decreases, those affected are sleepy, their performance deteriorates, and they experience headaches or diarrhea.

Long-term consequences

If the deficiency persists, the skin becomes dry and wounds heal poorly. Infections are piling up. In the long run, the muscles break down. The motor skills are disturbed, the reflexes slow down. The retina becomes ill. Inside, the cells disintegrate faster.

Why old people?

There is a good reason for the advanced age of the participants: Seniors in particular suffer from diseases due to a lack of magnesium. Many diseases that occur primarily in old age are also related to a lack of magnesium (and a lack of other minerals).

Blood sugar drops

Participants also saw their blood sugar and LDL cholesterol levels drop.

Copper, manganese and unsaturated fats

Hazelnuts offer even more vitamins and minerals, including vitamin B 6, beta carotene, folic acid and vitamin C, copper, manganese and healthy fats (nut oil). There are also iron, potassium, zinc and calcium.

Calorie bomb

But beware. Do not confuse the wealth of minerals and vitamins with diet food. Hazelnuts have 644 calories per 100 grams. Healthy or not, if you consume more calories than you consume, you gain weight.


In Germany, the hazelnut grows in the garden, on the edge of the forest, in hedges, in the sun and in partial shade. Our hazelnuts in the supermarket, however, come from Turkey, Italy and just from the US state of Oregon, in which the study was carried out. (Dr. Utz Anhalt)
