Health Benefits of Onions

Onions belong to the lily family, which also includes garlic, leeks, chives, scallions, and shallots. Early American settlers used wild onions to treat colds, cough, asthma, and to repel insects. Onions are effective against many bacteria, including Bacillus subtilis, Salmonella, and E. coli. There are many different types of onions, including red, yellow, white, and green. Each different type of onion has its own unique flavor, from very strong to mildly sweet. The high level of sulfur-containing compounds gives onions their unique odor. The strongest smelling onions provide the most health benefits. The best choice is yellow onions, followed by red onions, and then white onions. They are a significant source of vitamins B6 and C, dietary fiber, chromium, folate, manganese, potassium, copper, and phosphorus.


There are many good health benefits involved with onions. A regular diet including onions can lower cholesterol levels and high blood pressure. This can help to prevent atherosclerosis and diabetic heart disease. It can also reduce the risk of heart attack and stroke. Onions are able to increase good-type HDL cholesterol and reduce total cholesterol levels to make a person healthier. Onions are good for diabetics because they contain allyl propyl disulfide, which lowers blood sugar levels by increasing the amount of free insulin available. They also contain thiosulfinates that reduce the symptoms of diabetes. Colorful onions, such as red or yellow, contain the most thiosulfinates. It is best to eat onions raw or lightly cooked because heat diminishes thiosulfinates. Onions contain sulfides which might lower blood lipids and blood pressure.


Onions contain flavonoids, such as quercetin, that can reduce the risk of developing colon cancer by stopping the growth of tumors and protecting colon cells from the damaging effects of certain cancer-causing substances. The flavonoids improve the integrity of blood vessels and decreases inflammation. They also provide protection against cardiovascular disease. Quercetin protects the body against stomach ulcers and colon, esophageal, and breast cancers. Quercetin extract enhances physical performance and endurance.

Other interesting facts about onions are that onion extracts are good at relieving coughs and colds, asthma, and bronchitis. They decrease bronchial spasms and allergy-induced bronchial constriction in asthma patients. They are very rich in chromium, which is a mineral that helps cells respond to insulin. They are effective against osteoporosis. In osteoporosis, they destroy osteoclasts so that they don't break down bone.

Onions are safe to eat for most people but eating too much of this food may cause stomach distress and gastrointestinal irritation that might cause nausea or diarrhea. Cutting onions under cold running water is good at reducing watery eyes and eye irritation. Cut onions should either be stored in a sealed container or wrapped tightly in plastic wrap and immediately refrigerated. Uncut onions should be stored in a cool, dark, and dry place.

Health Benefits of Ginger

There are positive health benefits to ginger. Fresh ginger and ginger root have compounds that can fight certain cancer cells and slow the growth of tumors. For many years, ginger root has been used to treat nausea, pain, swelling, and cold symptoms. Studies have shown that regular use can lower cholesterol levels, help to stabilize blood pressure and glucose levels, and reduce blood clotting.

Ginger root is safe to use as long as it is used in reasonable amounts. A safe dose would be 100 mg per day. There have not been any severe side effects reported when higher doses are taken, except in people who are allergic to ginger root. The most common allergic reaction is excessive burping.

Ginger capsules are sold for medicinal purposes in pharmacies in many other countries. They are not sold for medicinal purposes in pharmacies in the United States. They are sold as capsules in the United States as dietary supplements. The FDA classifies it as a food and not a drug.

Fight Cancer with Soy

Soy contains compounds called isoflavones that can prevent the growth of tumors and block the stimulation of cancer cells through hormones, such as estrogen and testosterone. There are also other substances in soy, such as saponins, phenolic acids, phytic acid, phytosterols, and protein kinase inhibitors, that have anticancer properties. There are isoflavone supplements currently available on the market in pill form.

Use Cabbage to Help Beat Cancer

Cabbages, cruciferous greens, brussels sprouts, bok choy, Chinese cabbage, broccoli, and cauliflower contain substances called sulforaphane and indole-3-carbinols, which are anti-cancer molecules. These two molecules help to detoxify the body of certain carcinogenic substances and can help stop precancerous cells from developing into malignant tumors. They also contain other anti-cancer substances, such as glucosinolates and myrosinase enzymes. They also help to kill cancer cells and block tumor growth.

Increase Metabolism with Tea

There are catechins and thermogenic properties in green and oolong teas that can increase metabolism and speed up fat oxidation. One cup of green tea can increase metabolism by 4 percent for 1 and 1/2 hours. One cup of oolong tea can increase metabolism by 10 percent for 1 and 1/2 hours.

Green tea is also an antioxidant that is rich in compounds called polyphenols that reduce the growth of new blood vessels that feed tumors. It is also a good detoxifier that activates enzymes in the liver that eliminate toxins from the body. It has even been shown to increase the effect of radiation on cancer cells to help cancer patients. It prevents the formation of free radicals that can cause diseases, such as cancer, stroke, and heart disease.
