Lipids are found in the form of lipoproteins in the human body, so the clinical term hyperlipidemia mainly includes certain types of hyperlipoproteinemia. In order to reduce blood lipids, some dietary treatments should be applied to help improve it. At present, the first thing that is more advocated is to reduce fat intake with a proper low-fat diet. Try to avoid foods with fat content greater than 20% or more. The second is to apply more unsaturated fatty acid food. This unsaturated fatty acid is mainly linolenic acid, which is a protective effect for blood vessels. If the content of unsaturated fatty acids in food is relatively high, it is not easy to occur atherosclerosis caused by high blood lipids. Therefore, we need to have a low-fat diet on the one hand, and apply more essential fatty acids to provide lipoproteins that are beneficial to the body on the other. Like HDL is the scavenger responsible for stripping off the cholesterol deposited on the arterial blood vessel walls and bringing it back to the liver. Therefore, it is also beneficial to consume foods high in unsaturated fatty acids to increase HDL. Applying the above diet can reduce both neutral fat and cholesterol, and also raise HDL to keep vascular sclerosis and small arterial necrosis at bay, so it is reasonable to consume it appropriately.
