Rising rates of obesity in America always blamed Soda, candy and fast-food.

 A new study found that eating any one high-calorie or sugary food is obviously unhealthy and does not help in losing weight.

"While a diet of chocolate bars and cheese burgers washed down with a Coke is inadvisable from a nutritional standpoint, these foods are not likely to be a leading cause of obesity," said the study that was published by the Food & Brand Lab & Cornell in Ithaca, N.Y.

Americans who are underweight in fact eat more soda and sweet snacks than average-weight individuals. Persons who are obese and overweight individuals eat a lesser amount of soda, sweet snacks and salty snacks than average-weight individuals. While morbidly obese people ate smaller amount of snacks and salty snacks. Strangely, they eat 50% more French fries compared to average-weight individuals.

Researchers says people should not take away their much loved food in view of the fact that their sacrifice is somewhat related to their weight - unless their favorite food is French fries.

It's all about the calories a person takes in and out. The amount you eat versus the amount of nutrition you get.

Most Americans eat about 500 calories more every day. Aside from French fries, most Americans also eating their daily sodium -more than 75%- from processed food and restaurant food.

The number of calorie intake every day spiked for grains such as white bread, oil, dairy fats and added sugars.

"This means that diets and health campaigns aimed at reducing and preventing obesity may be off track if they hinge on demonizing specific foods," says David Just, professor and director of graduate studies in the Charles H. Dyson School of Applied Economics and Management at Cornell University, and co-author of the study.

"If we want real change we need to look at the overall diet, and physical activity. Narrowly targeting junk foods is not just ineffective, it may be self-defeating as it distracts from the real underlying causes of obesity."

In general, diet noticeably plays a role and, according to a current study, populace in some U.S. states is more obese than others.
