What Can Cause Obesity 1(revised version)

What Can Cause Obesity

I am walking in the street of Portland, Going from 21st avenue to 23rd. I am looking at stores, restaurant, and people who are talking to each others.I stopped for a second, thinking to myself where could this delicious smell comes from? People are sitting at restaurant and waiting for their foods. Waitress coming, and she has two plates of Berger with french fries in her hand. Fast Food! This is what American really likes. Right? Is that the reason of obesity and overweight in United State?

If you ask people around you that what is the reason that America  is suffering from obesity, most of people think fast food are the main reason. Look around. You can't go a mile without seeing McDonald's and other Fast food branches.
     

 Now, let's look at this issue from different view. According to National Heart, Lung and Blood Institute, “A lack of energy balance most often causes overweight and obesity. Energy balance means that your energy IN equals your energy OUT. Energy IN is the amount of energy or calories you get from food and drinks. Energy OUT is the amount of energy your body uses for things like breathing, digesting, and being physically active.” Overweight and obesity happen over time when you take in more calories than you use. If you want to have a healthy weight, your energy IN and OUT should not be balance every day. the importance is that you have energy IN and OUT balance over long period of time.

Nutritious vs. Income

Nutritious vs. Income

What we choose to eat plays a huge role in determining our risk of gaining too much weight. A study done by the Centers of Disease Control showed that since 1980, one third of our adult population has become overweight and are suffering from obesity. America is the richest but also the fattest nation in the world. This is crazy. Right?

Base on my research, the higher rates of obesity found in low-income and racial ethnic minority groups in the U.S. Environmental barriers to healthy eating are often greater for people who have lower incomes and less education. I think there is a relationship between supermarket access, diet, and obesity. Low-income neighborhoods are less likely to have access to large supermarkets that offering high quality and low-cost food, compared to middle-income neighborhoods. Low-income families face additional barriers to healthy eating that may contribute to the higher rates of obesity seen in lower-income groups. Healthy foods, such as vegetables and fruit are more expensive than less healthful foods, such as chips and sweets, and may be too expensive for low-income families. Imagine you come back from work, and you are really hungry. Would you prefer to buy your food from local food trucks that is 1 minute walking from your house or you choose to drive 15 minutes to closest supermarket to buy healthy food? I am not lazy but after 8 hours work I don’t think it would be a good idea to go somewhere far!

Cellphones and Health Risks

Cellphones and Health Risks

Do you think your cell phone can increase your brain activity? Does it affect your skin? Do you think it can affect your sperm viability? Is it safe for pregnant women or children? Do you think use a hands-free headset can decrease the risk of problems cause of cellphones? Do you think our phones have enough safety standards strict? Does cellphones have any health effects?

          Electromagnetic waves generated by cellphones facilitate our communications throughout the world. These waves have a lot of effects on the human body as well as our daily lives. The effects of electromagnetic waves cause many problems and diseases in the human body for example like cancer. Nowadays, cancers caused by these waves have increased in conjunction with increased mobile users. The effect of the electromagnetic radiation of cellphones depends on the age of the human being. The effects have been higher in children and teenagers in comparison to adults.

Some articles from news and medical websites can be found on the Internet that shows health consequences of using cellphones. Brain tumors and male infertility are the examples of these results. An article from Fox News by Dr. Marc Siegel states, “An ongoing multi- center trial in 13 European countries examining the cell phone use of more than 5,000 people with brain tumors appears to show an increased incidence in brain tumors in those who used cell phones. Further, the side of the brain affected appears to correlate with the side the cell phone was used”. Scientists advice us to use hands-free devices such as earphone that can decrease the risk of developing brain tumors. On the other hand, some studies in animals and humans have shown cell phone usage to be associated with abnormal sperm motility, morphology, and viability. “Cell phones emit radiation in the form of electromagnetic waves, which may have adverse effects on the Leydig and Sertoli cells (both necessary for development of sperm) within the testicle”(Wakehealth).
