Healthy?

Ok... So i have been saying "which one is the healthiest", but what is the classification of healthy!?! .........................................................................
I classify healthy with the following: the one that is the most organic and natural, the one that has the least trans fat and saturated fat, the one that has none or the least amount of bad chemicals in it. The chocolate bar with the least amount of cholesterol and sodium. Oh and the least amount of calories too.
