+ Legume, Health
  * Legumes contain many healthy nutrients, such as protein. They are a good source of protein for vegetarians and vegans, people who do not eat meat. They also contain fibre, which promotes a healthy digestive system. However, they contain some nutrients which humans struggle to digest. It is recommended that a legume is soaked in a weak acid for about 10 hours before cooking, to destroy these nutrients. Some amino acids, such as methionine, are not abundant in some legumes but are needed to help the body use protein
  - What legumes have in common
  * Legumes grow from the carpel, the female reproductive part of a plant. The fruit of a legume is found inside a pod that can be split on both sides. However, there are some foods that grow inside pods that are not legumes
