For mental workers, daily work is destined to use all kinds of brains, and if it is a more brain-burning type of work, the brain output will be more. In order to replenish the brain, some people will choose to eat walnuts to achieve their goals. Walnuts are a very common kind of nuts, the shape is indeed somewhat similar to the human brain, from the perspective of traditional Chinese medicine to complement the form, eating more walnuts will indeed have a certain effect of nootropic and brain supplementation. For middle-aged and elderly people, eating some walnuts can also prevent the occurrence of Alzheimer's disease.
Walnuts themselves contain a lot of oil, so some people think that middle-aged and elderly people with high blood lipids or high blood lipids should not eat walnuts, otherwise it will affect their health. However, recently, a medical journal published a new research report showing that eating walnuts in moderation is beneficial to lowering blood lipids. So, can eating walnuts really lower blood lipids? Why do walnuts have so much oil, but they can still achieve the effect of lowering blood lipids after eating? We might as well find out.
I believe that people who have eaten walnuts have this feeling, that is, the oil of eating walnuts is indeed richer. It stands to reason that eating foods with a lot of fat will indeed have an impact on the body's blood lipids, resulting in an increase in blood lipids, so people with high blood lipids or high blood lipids cannot eat walnuts, and this causal logic relationship is in line with the basic cognition of the public. However, there is not necessarily a scientific basis for assumptions. And the results of the study published in this medical journal illustrate this point.
According to the study, eating some walnuts in moderation every day will not only not lead to an increase in blood lipids, but also help reduce LDL cholesterol in the body. According to the data of this experiment, the cholesterol level in the body of the volunteers who ate walnuts decreased by about 4.4% and the LDL cholesterol level decreased by 3.6% after two years. The volunteers who did not eat walnuts did not have much difference in blood sugar and blood lipids.
Therefore, the conclusion of the study shows that eating walnuts can help lower blood lipids to a certain extent. Many people may question, why walnuts have so much oil, but after eating, they can still achieve the effect of lowering blood lipids?
In fact, not all oils and fats will have an impact on the body's blood lipids after entering the human body. Generally speaking, there are two types of blood lipids, one is cholesterol lipids and the other is triglycerides. Oils and fats are generally divided into two types, one is saturated fatty acids and the other is unsaturated fatty acids. The main thing that causes abnormal changes in blood lipids is saturated fatty acids, which will affect the metabolism of blood lipids after entering the human body, so excessive intake of saturated fatty acids will make the human body prone to hyperlipidemia and other cardiovascular and cerebrovascular diseases. Unsaturated fatty acids are relatively healthy, and the proper intake of some unsaturated fatty acids by the human body is also helpful for promoting the metabolism of blood lipids and even caring for cardiovascular and cerebrovascular health.
Although walnuts look oily, because the oil contained in walnuts is mostly unsaturated fatty acids, for patients with hyperlipidemia, eating some walnuts appropriately on weekdays will not only not lead to an increase in blood lipids, but also help promote the metabolism of blood lipids in the body, which is very helpful for lowering blood lipids and stabilizing blood lipid levels in the body.
