In order to lose weight, have better skin and have more energy you need to eat all the salmon. While that is a slight exaggeration, "foods with omega-3 fatty acids add hydration to skin and decrease inflammation," says Bowe.
Norenius adds that omega-3s are responsible for healthy cell membranes and the overall health of the various cells in the body. "The stronger the walls of the cells, the more water is kept in, thus making skin cells look more vibrant, plumper and overall more youthful," she says. A good rule of thumb: Aim to eat fatty fish like salmon twice a week. Engelman also is a fan of upping your nutrient intake with vitamins (she recommends Erzo Prenatal Vitamins, which comes in gluten-free and dairy-free versions).
