Nuts are indeed rich in oil, but most of the oil belongs to fatty acids, and the content of unsaturated fatty acids is relatively high, which is of great significance to the human body. The content of n6 fatty acid in nuts is high. N6 fatty acid is an important component of sebaceous glands. In addition, it also participates in the synthesis of all membrane structures such as cell membrane and cerebral cortex.
Proper intake of n6 fatty acids can increase the content of "high density lipoprotein (HDL)" in blood. Our cholesterol can be roughly divided into two types-low density lipoprotein (LDL) and high density lipoprotein (HDL). The former is usually called "bad cholesterol" and the latter is called "good cholesterol". This is because the function of LDL is to keep cholesterol circulating in the blood to exchange substances. Excessive cholesterol can increase the concentration of cholesterol and induce hyperlipidemia, while HDL is.
Therefore, proper intake of nuts is equivalent to helping to regulate blood lipid concentration. In addition, nuts also contain a certain amount of n3 fatty acids, which is more important to human body. Two famous components in n3, namely "brain gold (DHA)" and "patron saint of the heart (EPA)", not only help to strengthen and benefit the brain, but also help to reduce the content of low-density lipoprotein, which is also beneficial to prevent cardiovascular and cerebrovascular diseases and hyperlipidemia. N3 has many additional potential functions, such as anti-depression and anti-inflammation.
But eating too much nuts is another matter, which is equivalent to eating too much oil and calories, which will naturally lead to obesity. Moreover, the disparity between n3 and n6 fatty acids in nuts is relatively large. Excessive intake will lead to excessive intake of n6, which may increase the probability of obesity, cellular inflammation and cardiovascular and cerebrovascular diseases.
