By now, most people know they should be eating more vegetables. But are there ways (get) more from the vegetables you already eat? A research (show) that when it comes to vegetables, it's not how much we eat but how we prepare them decides the vitamins and other nutrients(营养物) that enter our body.
Many studies show that people eat lots of vegetables have less heart disease, eye problems and even cancer (癌症). But raw (未加工的) vegetables are not always best. The researchers found that 198 Germans who eat raw food were short lycopene (番茄红素) , the matter found in (tomato) and other red vegetables. "There is an idea that raw foods are always going to be much (good)," says Steven K. Clinton, a professor. "For fruits and vegetables, sometimes a little bit of cooking can be helpful."
number of factors decide how the vegetables do good to people's health before they reach the table, (include) where and how they were grown and stored before being bought. No single cooking way is best. Some nutrients are easily lost in cooking if they (cook) in different ways.
