Health benefits of onions and carrots

The Queen of Vegetables – Onions

Onions originated in Southwest Asia and have been consumed as a vegetable for thousands of years. In Europe and America, onions are hailed as the "Queen of Vegetables."

Scientists have determined that every 100 grams of onion contains 40 mg of calcium, 50 mg of phosphorus, 1.8 mg of iron, 8 mg of vitamin C, as well as carotene, vitamin B₁, and niacin. Onions contain almost no fat, but they do contain prostaglandin A, diallyl disulfide, and sulfur amino acids. Prostaglandin A is a potent vasodilator that can reduce resistance in peripheral blood vessels and coronary arteries, counteract pressor substances such as catecholamines, and promote the excretion of sodium and other substances that raise blood pressure, thus lowering blood pressure and preventing thrombosis. Diallyl disulfide and sulfur amino acids have anti-arteriosclerosis and lipid-lowering functions. Observational studies have found that after consuming onions for a period of time, patients with hyperlipidemia experienced a decrease in cholesterol, triglycerides, and lipoproteins. Therefore, regular consumption of onions can stabilize blood pressure, reduce vascular fragility, and provide excellent protection for human arteries.

Onions are not only a health food for middle-aged and elderly men who are prone to cardiovascular diseases, but can also be used to prevent and treat diabetes and kidney edema. This is because onions contain organic compounds similar to the hypoglycemic drug tolbutamide and can produce quercetin in the body, which has a strong diuretic effect.

Modern medical research shows that onions contain the trace element selenium. Selenium is an antioxidant that can promote the production of large amounts of glutathione in the human body. The main physiological function of glutathione is to transport oxygen for cellular respiration. When the concentration of this substance increases, the incidence of cancer will decrease significantly. Therefore, onions are also a medicinal food with anti-cancer properties.

The Best Vegetable – Carrots

Carrots, also known as golden bamboo shoots, are renowned as "little ginseng" due to their rich nutritional value.

Medical research has found that every 100 grams of carrots contains approximately 1.0 gram of protein, 0.2 grams of fat, 1.1 grams of dietary fiber, 7.7 grams of carbohydrates, 0.04 mg of vitamin B₁, 0.03 mg of vitamin B₂, 0.41 mg of vitamin E, and 32 mg of calcium… Carrots contain an even higher amount of carotene, up to 4130 mg, which is 7 times that of rapeseed, 12 times that of celery, and 16 to 50 times that of Chinese cabbage.

Carotene's chemical structure is similar to that of vitamin A, and it can be converted into vitamin A in the human body, playing a vital role in maintaining normal vision, preserving the health of epithelial cells, and promoting growth and development. In addition, recent research reveals that carotene has other protective functions. Carotene can enhance the body's immunity, protect the body from free radical damage, fight tumors and degenerative diseases, and increase the level of high-density lipoprotein in the body, reducing the incidence and mortality of cardiovascular and cerebrovascular diseases such as stroke and coronary heart disease.

Excessive vitamin A intake can cause poisoning, but carotene is considered an extremely safe source of vitamin A. This is because carotene is only converted into vitamin A when the body needs it; once vitamin A levels are normal, the conversion stops. Therefore, consuming carotene is very safe.

It is evident that increasing dietary carotene intake is highly beneficial to health. Although my country's diet is primarily plant-based, fresh green vegetables and fruits are scarce or expensive in colder regions or during certain seasons. Reduced intake may lead to insufficient vitamin A levels. Carrots, often called "little ginseng," are inexpensive, nutritious, and rich in carotene. They can be eaten raw or cooked and are easy to store. Why not, male friends, enjoy them?
