Eating a diet rich in fruits and vegetables is important for good health. Find out why experts say Mother Nature's bounty packs better nutrients than supplements.
富含水果和蔬菜的饮食对身体健康很重要。已经发现为什么专家说大自然的丰富赠品比营养补充剂更有营养。
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.
如果我们吃什么是什么,那么许多人肯定会到处被绊倒,因为缺乏平衡。那是因为美国人平均每天吃三份水果和蔬菜——这跟卫生福利部和美国农业部新指导方针表明的我们每天应该根据所需的热量吃5—13份天然的最佳食物。
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?
所以,如果我们希望长得跟大力水手一样强壮的话,为什么不吃一些营养补充品来代替吞食一堆菠菜呢?
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.
