The above given verse states the nutritional values of different kinds of foods we eat, and which is better off.
Flour is ten times better than rice- flour here usually referred to wheat; Wheat flour is ten times better than rice. Milk is ten times better than flour (?) Meat has eight times more nutritional values and calories than milk and Clarified butter/Ghee has ten times more calorific values than meat.
Maybe Chanakya also wanted to tell that the foods with lesser calories should be eaten more often; if you notice the quote you’ll find that foods with more calories are listed in a descending order
This the exceptional wisdom of Chankya the ancient economist of India.
