5.Eating your vegetables will make you grow up big and strong
We tell our kids all sorts of untruths to get them to eat their vegetables, fruits, and nutritious stuff. One of the classics is that eating spinach (or other vegetables) will make you grow up to be a big, strong man (or woman). Vegetables can only go so far, however. Genetics are going to play a huge role in how big and strong you will really grow up to be. Luckily the kids don't know this, or we'd never get them to eat any healthy foods!
