HAZELNUTS
Hazelnuts (Forest Nuts) are a very high-calorie product. Their seeds (nuts) are characterized by a fairly high content of certain vitamins, minerals, proteins, but most importantly, unsaturated fatty acids (especially oleic acid) and phytosterols.
Hazelnuts are richin biotin (100 g contains 156.0% of the daily requirement), alpha-tocopherol (116.7%), vitamin B6 (pyridoxine) (32.3%), vitamin B1 (thiamine) (28.2%), pantothenic acid (19.2%), folic acid (18.3%), vitamin PP (nicotinic acid) (16.9%), gamma-tocopherol (14.3%), vitamin K (phylloquinone) (11.8%), and choline (9.1%).
The mineral composition is based on:
manganese (421.3%),
chromium (340.0%),
boron (264.3%),
vanadium (250.0%),
silicon (166.7%),
copper (136.3%),
cobalt (123.0%),
molybdenum (42.4%),
magnesium (41.5%),
zirconium (40.0%),
phosphorus (38.1%),
potassium (27.5%),
rubidium (27.0%),
strontium (25.0%),
nickel (23.3%),
iron (21.0%),
zinc (19.6%),
sulfur (19.0%),
calcium (12.9%).
Hazelnuts contain proteins (17.1%), which include essential and non-essential amino acids (20.0% and 17.9% of the daily requirement per 100 g, respectively). Hazelnuts are especially rich in the essential amino acid lysine (62.0%) and the non-essential amino acid arginine (36.4%).
Hazelnuts are distinguished by their content of unsaturated fatty acids (130.9%), which are dominated by the monounsaturated omega-9 fatty acid oleic acid: 100 g contain 45.409-47.960 g, which is a very high indicator (only olive oil has a higher content – 72 g per 100 g). It is known that oleic acid promotes the dissolution of cholesterol plaques in blood vessels and thus prevents the development of atherosclerosis. Therefore, hazelnuts are a good remedy for the prevention of atherosclerosis.
Hazelnuts also have a fairly high content of polyunsaturated omega-6 fatty acids (66.7%, namely linoleic acid).
Hazelnuts are also notable for their
phytosterol content (210.9% of the daily norm per 100 g), the majority of which is
beta-sitosterol (270.0%), which allows hazelnuts to be classified as
a women’s product (for more details, see
Avocado).
Hazelnuts contain fiber (44.0%), small amounts of starch (0.93 g per 100 g), and quite a lot of sucrose (3.35 g).
The total purine base content in 100 g is 10.0% of the daily norm.
The
oxalic acid content
in 100 g is 222 mg, which is
55.5% of the maximum permissible daily intake (for more details, see
Rhubarb).
It should be noted that
hazelnuts can accumulate the toxic trace element strontium (25% of the acceptable daily intake in 100 g).
