Red walnut has many functions. For example, red-skinned walnuts are rich in fat, and the main component is glyceride linoleate, mixed with a small amount of linolenic acid and glyceride oleate. These unsaturated fatty acids can provide nutrition, help increase serum albumin, reduce serum cholesterol and prevent arteriosclerosis, hypertension and coronary heart disease. So eating walnuts is good for cardiovascular and cerebrovascular diseases.

Walnut has certain effects of clearing away heat and toxic materials, killing insects and relieving itching, promoting diuresis and infiltrating dampness. It can not only relieve sores on the mouth and tongue caused by excessive internal heat, but also has a certain auxiliary therapeutic effect on some diseases such as tinea capitis and psoriasis.

Precautions:

Walnuts can't be eaten with strong tea, because walnuts are rich in protein and iron, and tea contains tannic acid, which will combine with iron and protein in walnuts to produce insoluble precipitate, which is not easy to be digested and absorbed, so it is forbidden to drink strong tea when eating walnuts.

You can't drink alcohol when you eat walnuts, especially white wine. Because walnuts are hot and dry, so is wine. Eating together is easy to add fuel to the fire and make people excited. Especially people with constipation and excessive internal heat should avoid eating these two things together to avoid nosebleeds.
