Age-old wisdom always touted green leafy vegetables to be really healthy and now 3 new studies have backed this age-old fact. These studies have revealed that a chemical called nitrate found in green vegetables such as spinach, lettuce and celery may aid heart health and reduce the risk of obesity and diabetes.
The details of the 3 studies are as follows:
1. The first study published in The FASEB Journal found that eating nitrate-rich greens helps in thinning the blood by reducing the production of a hormone called erythropoietin made by the liver and kidneys. This protein regulates the production of red blood cells in the body. Nitrate could help in lowering the blood’s thickness without compromising oxygen delivery. It may thus help in preventing clots and decrease the risk of strokes and heart attacks.
2. The second study published in The Journal of Physiology exposed rats to high altitudes to trigger the production of red blood cells. They then supplemented the rats with a nitrate-containing diet, equivalent to increased consumption of green leafy vegetables in humans. The study found that the nitrate-fed rats reported better protection against an array of heart and circulatory conditions than the rats fed a nitrate-free diet. The researchers found that nitrate increases the production of a compound that widens blood vessels, thereby improving blood flow. In addition, nitrate protects proteins in heart cells that are crucial for heart health.
3. The third study published in the journal Diabetes found that nitrate subjects “bad” white fat cells to the browning process, turning them in to the beneficial beige cells. These beige cells are similar to the brown fat cells, which burn fat to generate heat. Increased levels of brown fat cells are associated with reduced risk of obesity and diabetes. Hence, the researchers in this study hypothesised that inclusion of nitrate in diet could confer protection against these conditions.
Rising prevalence of diabetes, obesity and cardiovascular disease is a matter of concern. Any evidence in favour of greens surely reinforces their role in good health. So go green to lead an evergreen life!
