I havent read all the replies but what i have done recently to try and eat better during pregnancy is when i do my shopping i avoid the junk food aisles and i stock up on oranges (loving valencia ones right now) apples (jonagold mmmm) grapes, bananas, watermelon and rockmelon. And when im feeling peckish i either grab an apple or an orange. Or what i did the other day was made this huge fruit salad and it had me tied over from 1pm to dinner time. Replace all the foods you usually sit down in front of the telly with some nuts or fruit. If im wanting something sweet an orange or apple fixes that for me.
