Fat, Salt, & Sugar

Today I was looking for a snack, and was faced by the decision between cookies and carrots.  Maybe "decision" is too big of a word.  More like a brief moment of consideration.

While consuming the cookies, I thought about why they taste better than carrots.  And, if carrots are obviously the more healthy choice, why do they taste worse?  Why can't vegetables taste like cookies?

[sidenote: genetically alter spinach to taste like chocolate and you will be very very rich]

It turns out that our bodies need fat, salt, and sugar in small quantities for a healthy diet.  These nutrients are very rare in nature, and therefore highly desired by people.

So the moral of the story is that next time you go to McDonald's, and there is the option to have apple slices instead of french fries, think about how much better your life is than your prehistoric relatives' while consuming the salt-covered deep-fried goodness.
