Eat a cup of buckwheats a day and you'll be okay!Energizing and nutritious, buckwheat is available throughout the year and can be served as an alternative to rice or made into porridge.
Diets that contain buckwheat have been linked to lowered risk of high blood pressure. A diet high in buckwheat (100 grams per day, about 3.5 ounces). When researchers tested blood lipids, 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 also contains almost 86 milligrams of magnesium in a one-cup serving. Magnesium relaxes blood vessels, improving blood flow and nutrient delivery while lowering blood pressure—the perfect combination for a healthy cardiovascular system.

Eat more oats!A daily serving of whole oats rich in soluble fibre can reduce hypertension, or high blood pressure, and so reduce the need for anti-hypertensive medication.
Oatmeal and oat bran are significant sources of dietary fiber. This fiber contains a mixture of about half soluble and half insoluble fibers. One component of the soluble fibre found in oats is beta-glucans, a soluble fiber which has proven effective in lowering blood cholesterol. Soluble fiber breaks down as it passes through the digestive tract, forming a gel that traps some substances related to cholesterol, such as cholesterol-rich bile acids. This entrapment reduces the absorption of cholesterol into the bloodstream. The bad cholesterol, LDL, is trapped without lowering good cholesterol (HDL). Oats and grains are also one of the best sources of compounds called tocotrienols. These are antioxidants which together with tocopherols form vitamin E. The tocotrienols inhibit cholesterol synthesis and have been found to lower blood cholesterol. The accumulation of cholesterol is implicated in many types of cardiovascular disease. Oats, like all cholesterol-lowering agents, are most effective when consumed as part of a low-fat, high-fiber diet taken together with plenty of exercise. The beneficial health effects of oats are best if ½-1 cup (1½-3 ounces) of oats are eaten every day. One study found that the 1/10th ounce (3 grams) of soluble fiber from this amount of oatmeal decreased total cholesterol by approximately 2%, which correlates to a 4% decrease in coronary artery disease. Another study showed 1½ ounces (43 grams) of oatmeal resulted in a loss of 3% in total cholesterol and a 14% reduction in bad cholesterol after two months. Another study found that a 6-8 week diet of 1½-3 ounces (43-85 grams) of oat bran daily lowered total cholesterol by 20% and bad cholesterol (LDL) by as much as 25%. Another study found 3.5 ounces (100 grams) of oat bran (one-third of a cup of oat bran eaten twice a day) lowered cholesterol up to 15%. New research has also discovered that theantioxidants found in oats reduce cholesterol by reducing the ability of blood cells to stick to the inside of artery walls.
