The promises: Jump-start your quest to get your pre-baby body back, repair and restore damaged tissues, and obtain the vitamins and minerals you and your baby require.
The perks: New moms need plenty of nutrients, many of which some of these juices would provide, says Ian Smith, M.D., author of Super Shred: The Big Results Diet. For example, iron from spinach helps form new blood cells so you can replace any blood lost during delivery; vitamin C in watermelon assists in iron absorption and boosts your immune health so you can ward of minor illnesses; and B-complex vitamins from greens prevent post-partum depression.
The squeeze: You—and your baby—can’t thrive on micronutrients alone. “Although these juices are dense in vitamins and minerals, they lack a significant amount of calories, fat, and protein that is critical for the production of breast milk,” says San Diego nutritionist Tara Coleman. Breastfeeding moms need 500 additional calories a day or they may not produce enough milk, potentially slowing their baby’s weight gain and development, explains Gayl Canfield, Ph.D., director of nutrition at the Pritikin Longevity Center. And whether you had a C-section or a natural birth, your body has just been through some major trauma; cleansing—especially in the initial stages—adds an additional element of stress that could slow healing, Coleman says.
The verdict: Check with your doctor, especially if you’re breastfeeding, Smith recommends. In general it’s best for new moms to eat a nutritious diet of whole foods. In addition to nutrients essential for healing your body and helping your baby grow, they’ll provide more fiber to fill you up and potentially help with your weight-loss efforts, Canfield says.
