Do plant-based diets cause nutritional deficiencies and damage to health?

Plant-based diets, when planned appropriately, promote optimal health and reduce the risk of many common diseases such as cardiovascular disease. A balanced and colourful diet centred on fruits, vegetables, whole grains, legumes, nuts, and seeds will provide the body with plenty of healthful vitamins and components such as folic acid, vitamin K and dietary fibre and less unhealthy ones such as saturated fat. In the case of a plant-exclusive diet, some supplementation is recommended.
