Introduction
Usually thought of as a grain although in reality it is actually a fruit and is related to rhubarb and sorrel, part of the Polygonaceae family.
Buckwheat contains no gluten so it is a great substitute for people with celiacs and also those who have a food sensitivity to wheat.
One of the benefits of buckwheat is that it is low GI (glycaemic index), meaning that it does not significantly raise blood sugar levels.
The most common way to prepare buckwheat is to hull the kernels, known as groats. Kasha commonly consumed in eastern europe is roasted buckwheat groats.
Nutrition
Buckwheat facts:
- has more protein than rice, wheat, millet, or corn
- contains all 8 essential amino acids (which also helps the body to process the protein it contains), and is high in lysine and arginine
- contains linoleic acid
- contains vitamins B1, B2, B3, B5, E, and P
- is higher in minerals than grains, especially zinc, copper and manganese, also contains chromium, magnesium, phosphorus and folic acid
- has a healthful amount of monounsaturated fatty acids
Heart Health
Buckwheat helps reduce and stabilize blood sugar levels following meals as it lowers the body’s blood glucose and insulin responses. This appears to be due to the presence of chiro-inositol which according to preliminary research done by a Canadian team makes cells more sensitive to insulin.
It contains flavinoids (which are a type of phytonutrients) which are beneficial for heart and circulatory health. Flavinoids act as antioxidants, and help to prevent the blood from clotting. It contains high levels of antioxidant polyphenols including rutin which supports the circulatory system and helps prevent recurrent bleeding caused by weakened blood vessels. It also contains quercitin, thought to support healing in the body.
Buckwheat is the best cholesterol lowering food as it lowers LDL (bad cholesterol) and raises HDL (good cholesterol). It helps to eliminate fat and provide protection against arthrosclerosis. It contains proteins that reduce the activity of angiotension converting enzyme (ACE) meaning hypertension (high blood pressure) is reduced.
The magnesium (found in buckwheat) improves blood flow by relaxing the blood vessels which also leads to decreased blood pressure. A study in Iowa has shown that diets containing higher levels of magnesium lowers the risk of getting diabetes.
Fiber and Intestinal Health
Buckwheat contains dietary fiber in a soluble form that helps reduce blood cholesterol levels and the risk of colon cancer. It is high in resistant starch which helps reduce blood sugar levels (fagopyritols) and improve colon health. Diets high in fiber can help women avoid gallstones. Insoluble fiber speeds up the time food takes to move through the intestines and reduces how much bile acid is released.
Even more encouraging is that buckwheat may act as a prebiotic, encouraging the growth of probiotics (friendly bacteria) in the digestive tract
Liver Health
Because buckwheat contains many B complex vitamins it is recommended for liver disorders and illnesses where it is recommended to restrict the quantity of sugary substances consumed each day.
