In class writing --- May 16

The first blog I read is written by Shelby. She writes one kind of important meat in our daily life, fish. She is a pescatarian. She compares the benefits and the adverse effects. She finds some medical articles which are focus on the fish eating topic. These articles show that eating fish is good, because it provides Omega 3 fatty acids, plenty of protein, a lot of energy, and at the same time it prevents heart disease. On the other hand, she also writes the bad effects of eating fish. It includes a toxin element—mercury. It will go through the chain and accumulate in the fish body. So it is not good to eat predator fish. She also estimates that pregnant women should pay more attention when eating fish.  But in the end, she says no matter those academic articles or herself. The benefits are much overweight compared with the adverse effects. I learned thing from her blog. I never think there will be some bad influence on our body by eating fish. It demonstrates a theory. There is no thing is absolutely good in the world. The next blog I read is written by Bobby, he discuss the bad effect of caffeine. “At higher doses caffeine can lead to periods of inexhaustibility, as well as rambling speech and thought and rapid heartbeat. People can become addicted to caffeine and experience symptoms of withdrawal, including insomnia, neck cramps, headaches, nervousness and mild-depression.”  I don’t often drink Coffee, because these drawbacks are very obvious of me. I think maybe we can use tea to instead of Coffee or create a kind of drink that can keep us awake and don’t hurt our health at the same time.          .
