Protein without meat

David Purves asks how the dietary need for protein can be met from a meat-free diet (Letters, 17 April). The answer is simple - a balanced plant-only vegan diet can adequately provide all the proteins our body needs. Protein is found in most plant foods such as nuts, seeds, grains, legumes, beans and lentils. Being a vegetarian has never been easier and is the best choice that individuals can make for themselves, animals and the planet.
