My wife is pregnant from december 2nd 2013.what feed you suggest for her.

Healthy natural food: A woman should eat healthy, natural foods before, during, and after pregnancy. Healthy means low in animal fat (better fats like olive oil are fine), a moderate amount of protein, and a moderate amount of whole grain carb's (but very little sugar). Natural means unprocessed, with little salt, sauces, or preservatives. Salt may increase water retention or swelling. Hot sauce may worsen heartburn.
