nutrition in a nutshell

this might sound trite ... to simplify something to this degree but when i came across this quote in this book i was gobsmacked at the beauty of it, the trueness of it and the utter simplicity of something that can be made to seem so complicated.
Eat food. Not too much. Mostly plants.
Note of explanation: The author explains that by ‘food’ he means basic foods, such as: fruit, wholemeal grains, meat, vegetables, potatoes, eggs, cheese, milk and the like, that we usually find around the perimeter of a supermarket and not the processed, prepared foods that we find in the centre isles.
