Knowing the vitamins & minerals isn't enough, you have to consume it to get the benefits. But knowing how to incorporate it in your meal plan can sometimes be a challenge if it's a new food for you. Salads are a great way to boost your spinach intake. Purchase ready-to-eat spinach out of the bag and making a nice healthy-portion salad by including your favorite veggies and a low-calorie salad dressing. Spinach makes for great flavor addition to sandwiches, pitas, wraps, etc. by just adding a thick layer of leaves! Or, you could make a spinach and low-fat cheese omelet or egg scramble (using an egg substitute) to get more spinach in for breakfast.
