15 Jan 2019 --- A practical guide to navigating food portion sizes by simply using one’s hands or a spoon has been released by the British Nutrition Foundation (BFN). The guide seeks to help consumers understand which foods to eat, how often and in what quantities, to maintain a healthy weight and lifestyle. It is available in three forms, as a fridge poster with an overview of the recommendations, a booklet which expands on how to put the advice into practice and a digital, downloadable guide, with advice on portion sizes for a variety of foods.
