If you are what you eat is true then if I have tomatoes in my salad am I part girl?!
Answers: No....it does not mean you are part girl. The saying , "you are what you eat", means when you eat healthy things, you will be healthly, if you eat junk food, your body will be junky... Your body needs the right amount of vitamins and nutrients everyday in order for you organs to work properly..
If it makes sense in your world then yeah...whatever.
