Food safety problem has become one of the most concerning problems in daily life. Although many authorities put eyes on this field, there are still few incident breakout every year. The reports of food recall or new food microbiological problem  increase every year. So, who should be responsible for the food safety problems? This issue has been discussed for a long time. From where I stand, the first should be the government. They have the authority to set up rules and regulation to the industries. For example. The Food and Drug institution, they can make the strict regulation to make sure the food safety level. And they can do often and random spot check to different kind of  products provided by the industries, using this way to guarantee the quality of the goods.

My view on labeling GMO’s

In # 5: Labeling GMOs, Assigned Posts by ChunLeave a Comment

what is genetic modifying? In fact it is the process of natural selection to preserve and enlarge the part that in a favorable survival in the random nature genetic variation. We all know that GMO’s have both plenty of advantages and controversy. It can resist of the diseases and pests, so many farmer introduced the modified genetic crops to enlarge the yield and make more money. The crops for instance the soy were used to make oil, so should we label that it is the GMO’s? In my point of view, The GMO should not be labeled. In human knowledge about genetic information is including Mendel’s pea hybridization and Longping Yan’s super rice which is the mostly known modified crops to Chinese that ultimately produce high yields of grain and largely solve the food problems. It has lots of advantages but there are still thousand of people against that. The label may mislead the consumers due to the less knowledge about the GMO, so it may damage not only the profit of the company but also the  consumers’ right. Also, …

It was happened by my side. The food allergy is one of the issue that need our more attention on. A friend of mine, who was suffered from the gluten sensitivity problem, began to diarrhea for several days after she had the corn. And I found a strange phenomenon, if she had enough vegetables and fruits, the symptom would be less. At that time I guess it might be the fiber in those vegetables protect that. To be honest, in China less product in the supermarket would stable if it is the gluten free, it is not easy for the person who have such kind of concern to pick up whatever they like and safe. Like other countries have a lot of cases, in China the public has not been given enough attention to the gluten sensitivity. The logo, because may still in the stage of the popularizing less domestic identification imported pre-packaged food is relatively standardized. Another reason is that the most commonly allergy for adult is the peanut protein allergy and shrimp protein allergy. But I believe in …

Sometimes when we watch a picture of  a well-build person, we may admire him or her, and then have look at the extra meat on the bones… As for me, I might go on a diet and exercise for several days then quit.
