Why Fruits and Vegetables Are Vital
If we are what we eat, then many of us must be tripping all over the place due to a lack of balance. That's because the average American eats about three servings of fruits and vegetables per day — a stark contrast to the Department of Health and Human Services (HHS) and the U.S. Department of Agriculture's (USDA) new guidelines stating that we should be eating 5 to 13 servings of nature's best, depending on the number of calories you need.
So if we want to grow to be strong like Popeye, why can't we just down some supplements instead of devouring a pile of spinach?
Nutrients in fresh fruits and vegetables work together. Kristine Wallerius Cuthrell, MPH, RD, a research nutritionist and senior project coordinator for Hawaii Foods at the Center on the Family at University of Hawaii at Manoa, says that in the past five to 10 years, many large research studies have found that vitamin supplements don't provide the benefits that foods do. The 2005 Dietary Guidelines for Americans, created jointly between HHS and USDA and reviewed every five years, say that foods are the best sources of nutrients because they contain naturally occurring ingredients, like carotenoids and flavonoids.
"In addition to the substances we are aware of, there are many present in fruits and vegetables that have yet to be discovered. Food and the nutrients they contain aren't consumed singly, but with each other. As such, they may act in synergistic ways to promote health," Cuthrell says. For instance, eating iron-rich plants, like spinach, with an iron-absorbing enhancer, like the vitamin C in orange juice, is great for people who don’t get enough iron (typically young women).
