Many factors can affect your health. Bad eating habits can affect your health. As a teen, you can control this by either making sure you eat healthier or sticking to a diet plan.
It can also be bad for your health if you never exercise. You can control this by getting up and doing just 5 minutes of exercise each day.
I can think of some reasons
1) Foods with too many fats, sugar, salt, and high caloric foods, generally taste better than other foods like veggies or other healthy options. We naturally have a sweet tooth as a survival instinct, so we naturally crave those types of foods and satisfies our Reward System in our brains
2) Think of fast food vs. Grocery shopping. Which is cheaper? Fast food is simply cheaper, faster, and more convenient than cooking something healthy at home or eating with family. Americans are so busy and many low-income families simply cannot afford to eat healthily.
those are some reasons I hope this helps :)
Scientists are creating vaccinations that prevent people from getting bird flu. If the virus mutates, a new vaccine needs to be made. The vaccine needs to be tested, which can be dangerous. It also takes a long time for scientists to know whether the vaccine works.
