You can eat all you want and not gain a gram, Polish academic Joanna Harasym promises of her freshly patented zero-calorie buckwheat hull wafers which are also gluten-free and rich in antioxidants.

Aside from helping in weight management, Harasym explained her invention is also advantageous to diabetics and gluten-intolerant individuals as the chocolate-coloured and nutty-tasting wafers "are gluten-free and don't raise blood-sugar levels."
A researcher at the Economic University in the south-western Polish city of Wroclaw, Harasym says she is also looking into making buckwheat beer which, however, will not be calorie-free.
Native to North America and Asia, buckwheat is three-sided in shape, resembling a grain but is classified as a fruit-seed and regarded by many as a "super food" rich in minerals, antioxidants such as flavonoids and essential amino acids, key to good health but which the body cannot synthesize.
Buckwheat groats are a popular side-dish in Poland, served as an alternative to potatoes or rice.
