Spring is the best time of year to eat spinach, a crop that loves warm days and cold, nearly frosty nights, which bring out its natural sugars. In addition to being a great source of vitamin C and folate, two nutrients that strengthen your immune system and ward off allergies, spinach is also rich in a compound called betaine, which has been found to boost exercise performance. And if you think only carrots can keep your eyesight healthy, think again. Spinach contains lutein and zeaxanthin, two phytochemicals that may help prevent age-related macular degeneration, one of the leading causes of blindness.
