PIKESVILLE, Md. (AP) — If it weren’t for Amanda Gilley, Pikesville resident Orly Shalem would still be throwing away the most nutritious parts of her salad, thinking she was making the healthy choice.

Shalem, a 46-year-old mother of three, always considered herself food savvy. Yet she always shunned dark-leaf lettuce, preferring the lighter, crispier varieties. Then, in October, during a program at LifeBridge Health & Fitness in Pikesville, she met Gilley, a registered dietician and trained chef who taught Shalem that not all lettuce is created equal.
