Wanted to know how the usual diet/food Ahlulbayt (as) used to have in order to remain healthy?

The human body to function properly requires sufficient protien & other macronutrients along with micronutrients (calcium,vitamins,minerals) and so on..
As per our traditions, our Holy Imams(as) including Imam Ali (as) – was participated in numerous wars & battles – consumed very minimum food which seemingly weakens the body.

The Imam (as) says health comes from little food, little water and little sleep.
As for what was consumed, barley bread seemed to be the staple food.
