Oats are a rich source of fibre and, like other wholegrains, they release their energy slowly and steadily. This may help increase satiety, which in turn helps maintain a ‘full feeling’ for longer (1,2,3).
The British Dietetic Association (BDA) states:
‘Wholegrains are usually low in fat but rich in fibre and starchy carbohydrate; they often have a low glycaemic index (GI). This means they provide a slow release of carbohydrate into the blood which, together with fibre content, may help keep you feeling fuller for longer – aiding to control snacking and appetite’ (4).
Ultimately, however, further research is needed to help increase understanding in this area.
