What foods are incompatible with onions?

Onions should not be eaten with kelp, as eating them together will form stones, which is harmful to human health.

Eating onions alone can supplement calcium and strengthen bones, improve the intestinal environment, kill bacteria and prevent cancer, as well as promote weight loss and treat constipation.

Onions and fish should not be eaten at the same time. Fish is rich in protein, while onions contain oxalic acid. Eating them together will cause the oxalic acid in the onion to decompose, destroying the protein components in the fish and causing the protein in the fish to precipitate, making it difficult for the human body to digest.

Onions should not be eaten with shrimps, as eating them together can easily cause kidney stones and affect human health. Eating onions alone can supplement calcium and strengthen bones, improve the intestinal environment, kill bacteria and prevent cancer, as well as promote weight loss and treat constipation.

What are the five benefits of onions?

1. Prevent cancer

Onions are rich in selenium and quercetin. Selenium is an antioxidant that can stimulate the body's immune response, thereby inhibiting the division and growth of cancer cells, while also reducing the toxicity of carcinogens. Quercetin can inhibit the activity of cancer cells and prevent the growth of cancer cells.

A study of women in France showed that those who ate more onions and garlic had a lower risk of breast cancer.

2. Maintain cardiovascular health

Onion is the only known vegetable that contains prostaglandin A. Prostaglandin A can dilate blood vessels and reduce blood viscosity, thus lowering blood pressure, increasing blood flow in coronary arteries, and preventing thrombosis. Onions are rich in quercetin, which has a high bioavailability. Scientists' research reports point out that quercetin may help prevent the oxidation of low-density lipoprotein and provide important protection against atherosclerosis.

3. Antioxidant

Flavonoid compounds in onions have strong antioxidant effects due to their phenolic hydroxyl structure. In addition, onions can also treat vitamin deficiency, especially prevent and treat scurvy and heavy metal poisoning. Onions can also relax, smooth hunger, promote diuresis, lower blood pressure, and regulate the physiological balance and metabolism of the human body.

4. Stimulate appetite and help digestion

The special smell of onions can stimulate gastric acid secretion and increase appetite. Experts have also shown that onions can increase gastrointestinal tension and promote gastrointestinal motility, thus stimulating the appetite and having a significant effect on loss of appetite caused by atrophic gastritis, insufficient gastric motility, indigestion, etc.

5. Improve eye fatigue

The glutathione contained in onions can promote the synthesis of corneal collagen and maintain the transparency of the lens. Experiments have found that glutathione can improve eye fatigue and blurred vision.
