Foundation of Nutrition I

In these new times, food is taken in a very different perspective by the people. As in the name of looking good, skinny, or zero size we usually see people starving themselves, not eating the correct amount or dieting the whole time, and moreover taking the diet into a completely wrong direction that is by surviving only on fluids or salads which is completely wrong. Some people are also seen following the FAD diets which are really harmful to one’s health.



On the other hand there are people who can be seen binging the whole day on snacks that are food containing excessive amounts of sugar, salt or are either fried. Or gorging on food by not realizing it and going through emotional eating, stress eating etc. and gaining weight that is turing overweight or obese. By increasing weight people also invite health problems that go from diabetes, hypertension to cardiovascular diseases.
