Apart from its high content of monounsaturated fatty acids, relatively resistant to oxidation, nuts contribute significant quantities of substances that protect against the action of free radicals thus decreasing the toxic effects of the latter.
The antioxidant content of nuts in a special way of almonds and hazelnuts, is considerable, and, almonds show a concentration of vitamin E (or tocopherol) than 20 mg/100g and hazelnuts concentration this compound is above 40 mg/100g.
The presence of such substances, protective action against harmful free radicals, gives the nuts an additional heart-healthy effect, mainly due to the ability of tocopherols to protect low-density lipoprotein (LDL) against action of free radicals, preventing their transformation into modified particles, not recognized by LDL receptors and particularly harmful to the cardiovascular system.
Folic acid plays a crucial role in the metabolism of homocysteine resulting in a significant reduction in the concentration of the substance, which helps to cushion the negative impact of this compound and, thus, the rate of progression of atherosclerosis.
