Medical experts believe that a large intake of unsaturated fatty acids will damage the erythrocyte membrane and mitochondrial membrane, which is not good for diseases. Therefore, it is suggested to take about 0.6 mg of vitamin E per 1 g polyunsaturated fatty acids to protect the biofilm from damage. Therefore, people with coronary heart disease should eat more foods rich in vitamin E, such as wheat germ, hard fruit, coarse grains, sunflower oil, safflower oil and soybean oil. Take vitamin E capsules under the guidance of a doctor if necessary.

The study also found that fish oil not only has a high P/S ratio, but also has a longer fatty acid carbon chain and higher unsaturation compared with vegetable oil, so it has a better cholesterol-lowering effect. Some marine fish, especially hairtail, have low cholesterol content and high fat P/S value, so it is beneficial for patients with coronary heart disease to eat hairtail frequently.
