Health Benefits

Onions, like garlic, are members of the Allium family, and both are rich in

powerful sulfur-containing compounds that are responsible for their pungent

odors and for many of their health-promoting effects. Onions contain allyl

propyl disulphide, while garlic is rich in allicin, diallyl disulphide, diallyl

trisulfide and others. In addition, onions are very rich in chromium, a trace

mineral that helps cells respond to insulin, plus vitamin C, and numerous

flavonoids, most notably, quercitin. Blood Sugar-Lowering Effects

The higher the intake of onion, the lower the level of glucose found during

oral or intravenous glucose tolerance tests. Experimental and clinical evidence

suggests that allyl propyl disulfide is responsible for this effect and lowers

blood sugar levels by increasing the amount of free insulin available. Allyl

propyl disulfide does this by competing with insulin, which is also a

disulphide, to occupy the sites in the liver where insulin is inactivated. This

results is an increase in the amount of insulin available to usher glucose into

cells causing a lowering of blood sugar.

In addition, onions are a very good source of chromium, the mineral

component in glucose tolerance factor, a molecule that helps cells respond

appropriately to insulin. Clinical studies of diabetics have shown that chromium

can decrease fasting blood glucose levels, improve glucose tolerance, lower

insulin levels, and decrease total cholesterol and triglyceride levels, while

increasing good HDL-cholesterol levels. Marginal chromium deficiency is common

in the United States, not surprising since chromium levels are depleted by the

consumption refined sugars and white flour products as well as the lack of

exercise. One cup of raw onion contains over 20% of the Daily Value for this

important trace mineral. Cardiovascular Benefits

The regular consumption of onions has, like garlic, been shown to lower high

cholesterol levels and high blood pressure, both of which help prevent

atherosclerosis and diabetic heart disease, and reduce the risk of heart attack

or stroke. These beneficial effects are likely due to onions' sulfur compounds,

its chromium and its vitamin B6, which helps prevent heart disease by lowering

high homocysteine levels, another significant risk factor for heart attack and

stroke. Onions have been singled out as one of the small number of

vegetables and fruits that contributed to the significant reduction in heart

disease risk seen in a meta-analysis of seven prospective studies. Of the more

than 100,000 individuals who participated in these studies, those who diets most

frequently included onions, tea, apples and broccoli-the richest sources of

flavonoids-gained a 20% reduction in their risk of heart disease.

Support Gastrointestinal Health.

 

The regular consumption of onions, as little as two or more times per week, is

associated with a significantly reduced risk of developing colon cancer. Onions

contain a number of flavonoids, the most studied of which, quercitin, has been

shown to halt the growth of tumors in animals and to protect colon cells from

the damaging effects of certain cancer-causing substances. Cooking meats with

onions may help reduce the amount of carcinogens produced when meat is cooked

using high heat methods.

Boost Bone Health

Milk isn't the only food that boosts bone health. Onions also help maintain

healthy bones, suggests a study published in the Journal of Agricultural and

Food Chemistry.

 

A compound newly identified in onions with the long complex name of

gamma-L-glutamyl-trans-S-1-propenyl-L-cysteine sulfoxide, GPCS, for short,

inhibits the activity of osteoclasts (the cells that break down bone). The more

GPCS given in this animal study, the more the bone resorptive (breakdown) action

of osteoclasts was inhibited. Onions may be especially beneficial for

women, who are at increased risk for osteoporosis as they go through menopause.

Fosamax (Alendronate), the drug typically prescribed to prevent excessive bone

loss, works in a similar manner, by destroying osteoclasts, so they do not break

down bone. Potential negative side effects of Fosamax include irritation of the

upper gastrointestinal mucosa, acid regurgitation, esophageal ulcers and

erosions. Potential negative side effects of eating onions: onion breath.

 

Anti-Inflammatory and Anti-Bacterial Activity

Several anti-inflammatory agents in onions render them helpful in reducing the

severity of symptoms associated with inflammatory conditions such as the pain

and swelling of osteo- and rheumatoid arthritis, the allergic inflammatory

response of asthma, and the respiratory congestion associated with the common

cold. Both onions and garlic contain compounds that inhibit lipoxygenase and

cyclooxygenase (the enzymes that generate inflammatory prostaglandins and

thromboxanes), thus markedly reducing inflammation. Onions' anti-inflammatory

effects are due not only to their vitamin C and quercitin, but to other active

components called isothiocyanates. These compounds work synergistically to spell

relief from inflammation. In addition, quercitin and other flavonoids found in

onions work with vitamin C to help kill harmful bacteria....

Thankyou for this I knew some of it but not all. I do like my onions

and garlic.

" Milk isn't the only food that boosts bone health. "

 

I understand milk to be a major culprit in osteoporosis.

Good reading,
