While we are unable (don't have the ability 不是没有能力,而是无法) to change the development of food industry,we can change the structure of our diet in terms what we can and cannot eat.To maintain a good health has received increased attention from the masses.My family is no exception.Since 2007,we have been on diet for purposes of keeping healthy.Prior to 2007,as I clearly remembered,every meal in my grandpa’s house,there were three or four types of meat served on the table,and there were no vegetables.Later we learned that many elderly folks who ate only meat and no vegetables had been diagnosed with a lot of physical symptoms.At that time,my mom was also majoring in nutrition.With my mom's help,our family started a planned structure of healthy diet consisting mainly of vegetarian meals.At first,this planned diet was difficult for us to accept.But we had no alternatives.For grandma and grandpa,their workload was quite heavy and vegetables were hard to meet their needs and made them feel rather weak.But a month later,their body mass index decreased a lot and they never felt they were so healthy then.As they gradually began to understand the necessity of changing eating habits,the meals gradually became less oily,less salty,and less sweet.This change in diet structure has had an important,positive impact on the health of the whole family.
