Moms are often filled with kind words of wisdom. But when it comes to food and nutrition, is their advice always scientifically accurate? In the following multi-part series, I'll take a closer look at some of the more common things moms often say and determine if they're fact or fiction. Enjoy! 

Carrots are good for your eyes
Mom was right! Carrots contain beta-carotene, a carotenoid pigment found in bright orange fruits and vegetables that is also a precursor for vitamin A. Vitamin A plays a major role in eyesight by preventing night blindness and helping with the maintenance of a healthy, clear cornea (outer membrane of the eye). Carrots, sweet potatoes, pumpkins, mango, cantaloupe, and apricots are all rich sources of beta-carotene.

Carrots also contain a compound called lutein, an antioxidant almost always paired with zeaxanthin. Studies have shown that eating foods rich in lutein and zeaxanthin can increase the pigment density in the macula-and greater pigment density means better retina protection, and a lower risk of macular degeneration. Other lutein rich foods include kale, spinach, Swiss chard and other dark leafy greens.
