The dietary habits of Americans are a great cause for concern. Based on statistics from the Center for Disease Control (CDC), our dietary choices are making a major impact on our health. In the USA, heart disease is the leading cause of death, with close to 100 million Americans dying from heart disease-related problems annually; dietary habits are a major factor, responsible for these numbers. It is estimated that there are 50,000 fast food chains in America. In conducting this study, you will be able to determine the nutritional value of fast food offered at these restaurants.
