Recommended Daily Allowances

Recommended Daily Allowances Chart

When you're pregnant or breastfeeding, it's important to take a close look at your diet to make sure that you and your baby are getting all of the calories and nutrients you need. What changes should you make? To find out, look over the table below, which lists the recommended daily allowances for various nutrients before conception, during pregnancy, and while you're nursing your baby. The table also explains the importance of each of these nutrients.

The best way to improve your diet is by eating a variety of healthy foods. Taking a daily prenatal vitamin recommended by your health care provider will help fill in any nutritional gaps. (If you're a vegetarian or are on another special diet, be sure to talk to your caregiver about additional dietary changes you may need to make.) Remember, too, that "eating for two" doesn't mean twice as much. You need just 300 extra calories a day (400 while nursing) - equal to one glass of milk, a banana, and 10 crackers.

These additional nutrient requirements can be taken in by choosing the right kinds of foods. For instance, green leafy vegetables are both high in folic acid and iron. Calcium can be taken in through dairy products and also through foods such as salmon, beans, and tofu. Dairy products are helpful in getting nutrients such as phosphorous, riboflavin, Vitamin A, and Vitamin D.

Although pregnancy requires additional nutrients, it doesn't require a drastic change in caloric intake. Remember, don't skip meals and keep saturated fats to a minimum.
