     How to eat healthfully can be especially complex for working women who often have

neither the desire nor the time to cook for themselves (or for anyone else )．Registered

dietitian Barbara Morrissey suggests that a few simple rules can help.

     "Go for nutrient－dense foods,"she suggests,"foods that contain a multiple of nutrients.

For example,select whole wheat bread as a breakfast food,rather than coffee cake. Or

drink orange juice rather than orange drink,which contains only a small percentage of real

juice-the rest is largely colored sugar water. You just can't compare the value of these

foods, the nutrient－dense ones are so superior,"she emphasizes.

     Morrissey believes that variety is not only the spice of life,it's the foundation of a healthful

diet. Diets which are based on one or two foods are not only almost impossible to keep up

the strength,they can be very harmful, she says, because nutrients aren't supplied in enough

amounts or balance.

     According to Morrissey,trying to find a diet that can cure your illnesses,or make you

superwoman is a fruitless search." As women,many of us are too concerned with staying

thin,"she says,and "we believe that vitamins are some kind of magic cure to replace food."

     "We need carbohydrates,protein and fat－they are like the wood in the fireplace. The

vitamins and minerals are like the match,the spark,for the fuel,"she explains." We need

them all,but in a very different proportions(部分). And if the fuel isn't there,the spark is

useless."
