Rationale:

13 CEREALS, GRAINS, TUBERS For both environmental and health reasons, there is a pressing need to vary the types of grains and cereals grown and eaten. The inclusion of a variety of sources of carbohydrates supports the ambition to enable a shift towards a greater variety of nutritious foods. 

12 BEANS, LEGUMES, SPROUTS Plant-based protein sources are included to support a shift towards eating more plants and fewer animals. Beans and legumes also enrich the soil in which they are grown and support the recovery of land as part of crop rotation. 

18 VEGETABLES With very few exceptions, most people around the world do not get the recommended amount of at least 200 grams (or three servings) of vegetables per day. Vegetables are nutrient packed and can easily and affordably be added to commonly consumed meals. 

3 MUSHROOMS Mushrooms are included because of their nutritional benefits and unique ability to grow in areas unsuitable for other edible plants. Their texture and umami flavour enable them to be adequate meat alternatives. 

4 NUTS AND SEEDS Nuts and seeds serve as plant-based sources of protein and fatty acids (omega 3 and 6) which can support a transition away from meat-based diets while ensuring optimum nutrition. They can be added to a wide variety of dishes for extra crunch and a nutrient boost. FOCUS ON SAVOURY FOODS Most calories consumed are from savoury meals.
