Buckwheat (Fagopyrum esculentum, Polygonum fagopyrum), despite its name suggests the wheat, comes from an oriental seedling, however, cultivated today almost everywhere, it is not even a graminaceous plant.
It contains, for 100 grams, the following quantities, expressed in milligrams :
- Potassium 460
- Phosphorus 345
- Magnesium 230
- Calcium18
- Selenium 8
- Iron 2
The content of the grains is highly caloric and contains vitamins and minerals that are interesting for health, as we can see from the table above.
Buckwheat, like barley and rice, has cardioprotective properties (1) and induces a sense of satiety even if it does not modify the high blood glucose values (2) in subjects with diabetes mellitus.
Health benefits attributed to Buckwheat (BW) include plasma cholesterol level reduction, neuroprotection, anticancer, anti-inflammatory, antidiabetic effects, and improvement of hypertension conditions. In addition, BW has been reported to possess prebiotic and antioxidant activities. In vitro and animal studies suggest that BW's bioactive compounds, such as D-chiro-inositol (DCI), BW proteins (BWP), and BW flavonoids (mainly rutin and quercetin) may be partially responsible for the observed effects. The purpose of this paper is to review the recent research regarding the health benefits of BW, in vitro and in vivo, focusing on the specific role of its bioactive compounds and on the mechanisms by which these effects are exerted (3).
