SEATTLE - The Food Pyramid has served as a nutritional guideline for years.

Now the USDA is putting a new spin on it - revealing a brand new nutritional guide just for women who are pregnant or breastfeeding. It's important, since knowing what foods to eat and how much weight to gain during pregnancy can get confusing.

"I think that a lot of women don't know what to do, and we tend to as providers send them out with the information that you should gain 'x' amount of weight during pregnancy but we don't actually give people the tools to do that," said Dr. Laura Riley, gynecologist.

The USDA's new food pyramid for pregnant women can be found at www.mypyramid.gov. Riley hopes the Web site will be a helpful resource for women.

"A lot of women are not going to have the resources to go see a nutritionist for an hour and sit down and review their diet," Riley said. "So this is a way of getting information outside of your doctor's office or provider's office and a way that you can do it on your own time."

All women have to do is type in their age, due date, height and weight to get their very own personalized nutrition plan.

"My pyramid for moms is really gonna provide some great advice for mothers during this period when they're so interested not only in their own nutrition but obviously the nutrition for the health of their child," said Charles Conner, Deputy Secretary of Agriculture.

All pregnant and breastfeeding women should see a doctor first and then they can use this plan in conjunction with the recommendations made by their OBGYN.
