Variety is the spice of life.
~ American proverb.

Variety is the spice of life, and this is especially true when it comes to food. The French think in "menus", the Italians have many "piatti" and Asians all share a lot of various small dishes.

Eating varied is good not only against boredom, but also makes sure that you get a variety of proteines, sugar, carbohydrates and fibres.
