The nutritional value of walnut kernel is extremely high, and it is rich in monounsaturated fatty acids, polyunsaturated fatty acids, lecithin, vitamin E and so on.
Monounsaturated fatty acids and polyunsaturated fatty acids can reduce the contents of cholesterol, triglyceride and low density lipoprotein in blood and prevent hypertension, coronary heart disease and hyperlipidemia. Vitamin E has the functions of improving immunity, resisting arteriosclerosis, preventing cancer, protecting eyesight and eliminating "senile plaque". Therefore, walnuts are good nutrients for the elderly.

Eating walnuts and boiled water is taboo;
1. Walnuts cannot be paired with pheasants. Walnuts should not be eaten with pheasants, nor should patients with pneumonia and bronchiectasis. Generally speaking, the daily weight of walnuts should be about 40 grams, which is equivalent to about four or five walnuts. At the same time, we should appropriately reduce the intake of other fats to avoid excessive calorie intake.
Walnuts can't go with wine. According to Ma Zhi's "Kaibao Materia Medica", "Eating walnuts makes people hemoptysis". It may be because walnuts are hot, eating too much produces phlegm fire, and white wine is also sweet and spicy, so eating together is easy to cause blood heat. Especially people with chronic hemoptysis should avoid eating. For example, patients with bronchiectasis and tuberculosis will have hemoptysis if they drink white wine, but they will also get sick if they don't eat it with walnuts.
Walnuts can't be matched with strong tea. Because walnuts are rich in protein and iron, and tea contains tannic acid, tannic acid will combine with iron and protein in walnuts to form insoluble precipitate, which is not easy to be digested and absorbed, so you should avoid drinking strong tea when eating walnuts.
4. Walnuts can't go with turtle meat. Turtle can improve human immune function, promote metabolism, enhance human disease resistance, and have the effects of skin care and delaying aging. But you should pay attention that walnuts and turtle meat are the same. Eating walnuts and turtle meat together will be toxic and affect health.
5. Walnuts can't be paired with soybeans. Soybean is known as the "king of beans", as "plant meat" and "green cow", with the most abundant nutritional value. But you should know that soybeans can't be eaten with walnuts, which will cause abdominal distension, abdominal pain and indigestion.
6. Walnuts can't be paired with wild ducks. Walnuts are very similar to wild ducks. Eating walnuts with wild ducks will be uncomfortable and easy to get sick.
