In addition to a proper workout, eating right is essential for pregnant women. Below are three smoothie recipes from Anderson.

Orange Smoothie

1.5 cups baby spinach (Pregnant women can also take Folic acid supplements, if they don't like spinach)

3 oranges

1 dried pitted date

Cinnamon (great for nausea, indigestion, etc. during pregnancy, but use in moderation)

1/2 cup coconut milk, or one fresh coconut with meat and water used.

Blend ingredients.

*1 cup of spinach provides a pregnant woman's daily intake of folate by 65 percent. Folate is pertinent in the development of a baby's brain and spinal cord.

Green Smoothie

3 cups spinach

1 banana

Ice or water

1 dried pitted date

1 apple

1.5 cups blueberries

(you can also add milk, but banana will give it "smoothie/milk" effect)

Blend ingredients.

3/4 cup Greek yogurt for calcium (and it has twice the protein that other yogurts have, helping to keep your bone structure strong as well as aiding in a baby's growing bone structure.)

1/4 cup Oat Groats (it's loaded with vitamins and fiber, and helps stabilize your blood sugar. You can substitute flax seeds.)

1 dried pitted date

1 cup raspberries

1 cup orange juice

Ice

Blend ingredients.
