'Don't diet': Expert reveals what expecting moms should be eating

What should you eat when you're expecting? Registered dietitian Lauren Cicinelli gets that question a lot, and her first rule of thumb during pregnancy is don't diet, unless your doctor tells you to.

What you and your baby need she says is a balance of healthy nutrient rich foods

“So we really want to make sure half our plate is non-startchy vegetables,” Cicinelli explained.

She said make sure you are eating protein in every meal and snack. Complex carbs are foods like brown rice, oatmeal, sweet potatoes and multi grain bread.

How much and what you need to eat will change during your pregnancy.

In your first tri-mester…

“General healthy diet for first tri-mester,” she said.

Second and third tri-mester...getting enough protein can be challenging if you're a vegetarian or vegan.

“Beans, nuts and seeds,” she said.

Cicinelli said cut back on processed or junk foods because they don't have the nutrients you and your baby need.

If you're pregnant or thinking about conceiving, you need to be taking a daily pre-natal vitamin and make sure you're getting enough folic acid and iron. Eating a balanced diet will get you most of what you need but a pre-natal vitamin will fill in the gaps.
