The web is full of food-related suggestions. Today I'm adding a few of my own.

1. Never skip a meal, including breakfast. Didn't wake up until noon? Eat your third meal
    at midnight.
2. Got a headache?  Eat something.
3. Feeling shaky? Eat something.
4. Got a stomach ache?  Eat something.
5. If a little voice in the back of your mind tells you a certain food will make you feel ill, listen to it. 

Next up is a reflection (of sorts) on a little book called Food Rules by Michael Pollan.
