The old wives tale is your eating for two. What leads to major weight gain is the idea that you now have a free ticket to eat anything. Pregnancy increases your energy needs and requires you to consume more calories than you normally would. Even though you are technically eating for two, however, your extra energy needs are well below what you probably think.The energy requirements increase about 300 calories per day. So choose wisely and eat extra lean protein or dairy as your extra calories and not the cake. Add broccoli, cauliflower, brussel sprouts, green peppers, and tomatoes to your diet for vitamin C. Every pregnant woman should have extra folic acid. Lima beans, black beans, and chick peas are a good source of folic acid. Beef , turkey, One cup of cooked beans,One-half cup of tofu 1 ounce of pumpkin, sesame, or squash seeds are great choices for extra iron.
