To fuel your body right, fill your basket with these 15 top foods for fit women

Do you dash down the aisles of the grocery store, tossing only familiar foods into your cart because you're too busy working, training and feeding your family to consider anything else? If so, you may be missing out on good nutrition. The best way to ensure that you perform optimally and recover fully—as well as keep your family healthy—is to stock your kitchen with these must-have items for the active woman.

ROMAINE LETTUCE
>> Why it belongs in your cart: The darker green leaves of romaine do more to boost bone health than its iceberg cousin because they offer more vitamin K—about 4 1/2 times more—which is needed to make bone protein. Women with the highest concentrations of vitamin K in their diets (at least 109 mcg per day, the amount in roughly 2 cups of romaine) have the most fractureresistant bones, according to a 1999 study in the American Journal of Clinical Nutrition. Romaine also provides folate, a B vitamin you need to prevent a type of anemia that saps your energy and derails your workout routine. Just 1 cup of romaine supplies 75 mg of folate, nearly 25% of what women require on a daily basis.

>>Choose the best: Pick brightly colored romaine with no tears or discoloration in the outer leaves. Just before eating, wash romaine with warm running water to gently remove dirt and debris. To save time and minimize waste, choose precut, prewashed lettuce.
