A psychiatrist who studies mental illness as only a
symptom of a physical disorder could most accurately be called a somatist. By
definition somatist came from the term ‘soma’ which means ‘body’. The study
only covers anything related to physical diseases as connected to the brain
(e.g. Somatoform disorder).
Items that belong to the five food groups in the USDA's MyPlate Food Guidance System are:
Veggies
Fruits
Dairy
Protein
Grains
so any one of them could be considered as one of the five food groups
Hope this helps :)
