均衡饮食与癌症-健康

Lifestyle has become an influential factor in determining an individual's health.Every year,cancer is responsible for thousands of slow and painful deaths.Nutritional scientists have long proposed a relationship between eating habits and cancer.
生活方式已经成为一个左右一个人是否健康的主要因素。每年，癌症是成千上万个慢性和痛苦死亡的罪魁祸首。营养学家早已经证实了饮食习惯和癌症之间的关联性。

Although the causes of cancer can be many,a well-balanced diet can certainly reduce the risk of the disease.Such a diet is usually defined as a mixture of foods that contain just the right amount of nutrition.Each day,our bodies need proteins,carbohydrates,fats,trace minerals,and vitamins to function well.
尽管致癌的原因可能有很多，但是一种营养均衡的饮食习惯必定能够减少得病的风险。这种饮食通常是综合了包含适量营养的一些食物。每天，我们的身体需要蛋白质，碳水化合物，脂肪，微量矿物质，和维他命来使它正常运作。

Different foods have different proportions of those nutrients,so careful selection is important in eating.Proteins are rich in milk,meat,and egg.Carbohydrates are abundant in sugar,rice,and bread.Fats are found in animal products.Seaweeds and fish can satisfy body's needs for trace minerals.Fruits and vegetables provide a tremendous amount of vitamins and antioxidants,which are particularly important in cancer prevention.To ensure a healthy tomorrow,spending a little time to manage your dietary intake will pay off later in life.
不同食物有不同比例的营养，所以慎重的选择食物很重要。牛奶，肉和蛋中含有许多的蛋白质。糖，米和面包含有丰富的碳水化合物，动物食品中含有脂肪。海藻和鱼类能满足身体对微量矿物质的需求。水果和蔬菜提供大量的维他命和搞氧化剂，这对癌症的预防特别重要。为了确保健康的将来，花点时间关注每天的饮食，这对未来的健康是很有助益的。
