From Dr Oz’s “Foods to fight aging” list, romaine lettuce is a leafy green vegetable high in vitamin A, a vitamin that helps revitalize skin by increasing cell turnover and encouraging new skin cell growth. Add 6 leaves to your salad or as a side with dinner for your daily allowance of vitamin A.
I use either romaine lettuce or mesclin greens in my lunch wraps. As well, we often use even amounts of romaine and other lettuces for salads.
From the incredible smoothies site (www.incrediblesmoothies.com) – 10 surprising nutritional facts about romaine lettuce:
