例如,胡萝卜和红薯中的β-胡萝卜素,已经显示可以帮助预防肺癌,但是如果以药丸的形式吃下去就对身体有害了。最新的研究表明成人服用钙补充剂会增加患心脏病的风险,而且对骨骼健康没有好处。(这就是为什么如今一些研究人员鼓励人们从饮食中获取营养。菠菜和西兰花就是很好的来源。)
Getting more isn't always easy. Supermarket produce can be expensive, making packaged snacks—already sweeter or saltier and higher in calories than fruits and vegetables—all the more tempting. A cheaper alternative: Grow your own. Home-grown produce has other advantages beyond its low cost. It's often tastier and arguably a bit more nutritious. Here's why:
获取更多营养并不容易。超市产品很贵,使包装的零食更加诱人,它们比水果蔬菜更甜或更咸,而且含有更多热量。一个更实惠的选择:自己种植。自产产品除了价格低还有其他优势。更加美味而且更有营养。下面是原因:
Those bright red bell peppers or crisp green beans at the supermarket are likely to have traveled many miles over several days before landing in your cart. Although both the vegetables are a good source of vitamin C—known for bolstering the immune system—a long journey from farm to table gives the nutrient ample opportunity to degrade, especially if exposed to heat. In fact, temperature is the most important factor in keeping harvested fruits and vegetables in good shape, says Diane Barrett, a food biochemist from the University of California, Davis, who helps teach best practices to locals who grow, ship, and distribute fresh produce. One would expect then that temperature is tightly controlled in transit, but in realty she says that does not always happen.
