Some people in our country eat fast food very often. Scientists

Most children love eating junk food at fast food restaurants. Fast food is very high in fat, which is harmful to our bodies. Fat makes our blood thicker, and in turn this makes it harder for our heart to pump. Secondly, fast food diets don't contain much fresh fruit, or many vegetables. As a result, our brains and bodies don't work as well and we feel tired and stressed.
