It's Wednesday night, you're home from work and hungry. What's your favorite go-to midweek meal?

Tacos with black beans and guacamole, lettuce, tomato and a sprinkling of cheese. Quick, easy, healthy and very satisfying. Good single girl food, too.

Help us avoid wasting hundreds of dollars at the health food store buying vitamins. What, if anything, do we need to be taking? 

Top 3: A good liquid multivitamin (they're more absorbable), a probiotic (good bacteria for the intestines) and an omega-3 supplement (fish oils or flaxseeds).

Why is America fatter than ever?

Because we eat crap. We don't eat real food, we eat processed food that is stripped and chemicalized. We eat an enormous amount of calories, but in the absence of the vitamins and minerals, our bodies are actually starving. That's why we're hungry all the time: We are literally starving.

We better go eat some tacos, then.
