Nowadays, some elderly people are really pitiful sometimes because they cannot enjoy many delicious foods due to high blood pressure, blood sugar, and blood lipids, but there is still a method, that is, to eat more onions. Onions can lower blood pressure and blood sugar, promote the excretion of sodium, and due to the presence of glibenclamide in onions, they can also lower blood sugar. Soluble dietary fiber can also be dissolved, so the intestines are comfortable, allowing for the consumption of more delicious foods, and can also prolong life.

1 Lower blood pressure. Onions are the only plant containing prostaglandin A, and they are the only known food containing prostaglandin A. They are a natural blood thinner, and prostaglandin A can dilate blood vessels, reduce blood viscosity, and thus produce a lowering of blood pressure, reduce blood flow in peripheral vessels, and increase blood flow in coronary arteries, preventing thrombosis. It also counteracts the effects of substances such as epinephrine in the human body that raise blood pressure and promotes the excretion of sodium, thereby lowering blood pressure. Regular consumption is beneficial to patients with hypertension, hyperlipidemia, and cardiovascular diseases.

2 Lower blood sugar. Onions also have a hypoglycemic effect due to the presence of organic substances similar to the hypoglycemic drug glibenclamide in onions, which can generate psoralen with strong diuretic effects in the human body. Diabetics can achieve a good effect of lowering blood sugar and diuresis by eating 25~50g of onions with each meal.

3 Improve constipation. The sulfur component in onions combines with protein in the large intestine or bacteria in the intestines to form hydrogen sulfide, which can promote peristalsis. Rich soluble dietary fiber can stimulate the intestines, making the movement more vigorous, and oligosaccharides can also inhibit the proliferation of harmful bacteria in the intestines, effectively improving the common constipation symptoms in women.
