Buckwheat Tea

A Grain That’s Good for Your Cardiovascular System Diets that contain buckwheat have been linked to lowered risk of developing high cholesterol and high blood pressure. The Yi people of China consume a diet high in buckwheat (100 grams per day, about 3.5 ounces). When researchers tested blood lipids of 805 Yi Chinese, they found that buckwheat intake was associated with lower total serum cholesterol, lower low-density lipoprotein cholesterol (LDL, the form linked to cardiovascular disease), and a high ratio of HDL (health-promoting cholesterol) to total cholesterol. Buckwheat’s beneficial effects are due in part to its rich supply of flavonoids, particularly rutin. Flavonoids are phytonutrients that protect against disease by extending the action of vitamin C and acting as antioxidants. Buckwheat’s lipid-lowering activity is largely due to rutin and other flavonoid compounds. These compounds help maintain blood flow, keep platelets from clotting excessively (platelets are compounds in blood that, when triggered, clump together, thus preventing excessive blood loss, and protect LDL from free radical oxidation into potentially harmful cholesterol oxides. All these actions help to protect against heart disease. Buckwheat is also a good source of magnesium. This mineral relaxes blood vessels, improving blood flow and nutrient delivery while lowering blood pressure-the perfect combination for a healthy cardiovascular system.
