Harmful oils and fats enter the body, which will aggravate oxidative stress and cause nephropathy deterioration. Therefore, patients with nephropathy should distinguish "good" and "bad" oils. Good oils and fats usually refer to unsaturated fatty acids, which are also divided into monounsaturated fatty acids and polyunsaturated fatty acids.
Saturated fatty acid is fatty acid, stearic acid, palmitic acid based, these two kinds of fatty acids are all white solid at room temperature. Therefore, oil high saturated fatty acid content is white solid, such as butter, suet and lard, are rich in unsaturated fatty acids of oil and grease.
The content of unsaturated fatty acid of vegetable oil on the body more healthy, can soften blood vessels, dredging thrombus. The so-called unsaturated fatty acid refers to the molecular structure of fatty acids in one or more unsaturated bonds, and according to the different unsaturated bond position is n-3, n-6 and N-9 fatty acids with alpha linolenic acid as the representative.
N-3 series fatty acids: alpha linolenic acid is an essential fatty acid of human body. It can be converted into twenty carbon five enoic acid and twenty-two carbon six enoic acid in the body. Fish, especially deep-sea fish, is rich in EPA and DHA.. The latter is an indispensable material for infant brain and eyesight development.
N-3 series of fatty acids can reduce blood lipids, improve blood circulation, inhibit platelet aggregation and atherosclerosis, and prevent thrombosis in adults. Therefore, it has good preventive effect on cardiovascular diseases.
N-6 series fatty acids are represented by linoleic acid. Corn oil and sunflower seed oil are rich in linoleic acid. They are also essential fatty acids of human body. They have important roles in reducing triglycerides, low density lipoprotein cholesterol and high-density lipoprotein cholesterol.
N-9 series fatty acids are represented by oleic acid. Olive oil and camellia oil are rich in oleic acid. They also have the effects of lowering cholesterol, triglycerides and bad cholesterol and increasing cholesterol.
Good oil intake is also limited. Good oil is also oil. Too much energy can cause too much energy intake, resulting in obesity and hyperlipidemia. In addition, good oil should pay more attention to reasonable cooking. High temperature frying will make good oil bad, which is not only wasted but also harmful to health.
