Onions Reduce Cholesterol Levels

Onions Reduce Cholesterol Levels

Tip of the Day: 

Onions not only have culinary benefits but also have health benefits. They have a therapeutic effect on the body. Though strong in flavor, they have high levels of polyphenolic compounds called flavonoids which help improve Cholesterol levels. Flavonoids are antioxidants that are:

  • Anticancer
  • Anti-inflammatory
  • Antiproliferative abilities ( stop cell growth)

Onions have the ability to raise the HDL cholesterol levels if you eat a raw onion a day for atleast 3 months to see the HDL levels improve significantly. According to Dr. Victor Gurewich of Tufts University, when his patients with very low HDL levels ate a raw onion a day, an average of 30 percent raise in HDL levels was observed.

In the late 1960s, an Indian researcher found that when two ounces of grilled onions were eaten with a meal containing 90 percent fat, cholesterol levels didn’t increase, blood platelets did not stick to each other and, and fibrinogen  ( blood clotting compounds) were not  produced. Onions are known to contain quercetin an antioxidant that decreases heart disease such as heart attack, hypertension, and hardening of the arteries.

Gall stone are also caused by high cholesterol levels.  The 2009, British Journal of Nutrition findings reveals that raw and heated onions reduced the development of cholesterol gall stones by about 39 percent in mice. However, its effectiveness on humans, still remains elusive.

Blood Sugar

Research shows that onions affect the blood sugar in humans. Allyl propyl disulphide ( sulphur compound) found in onions may increase production of insulin and reduce the levels of blood glucose. As per the findings published in the Environmental Health Insights in 2010, red onions were effective at reducing the blood sugar levels in diabetics up to four hours after eating.

Studies indicate that raw onions have more nutrition than cooked onions. When onions are simmered, the quercetin amount does not get degraded. By simmering onions on low heat, the quercetin content can be preserved.
