Avoiding Myopia

One other consequence of a poor diet could be myopia (nearsightedness).  A couple of years ago, Loren Cordain and company wrote a paper about the relationship between a high-carbohydrate diet and myopia.  The explanation is that during childhood, a diet high in refined carbohydrates alters hormone levels and affects the shape of the eyeball as it develops, causing nearsightedness.

Given this, children should be highly encouraged to consume a Paleolithic diet.  Another protective factor for myopia is breastfeeding.  Research shows that children who were breastfed are much less likely to be nearsighted than children who weren't.  Breastfeeding and a Paleo diet are what children really need, not the fake foods of modern society.
