Food And Nutrition Essay
Proper nutrition is one of the most essential elements to being healthy and living a long life. People deal with food every day, and food has been a part of life since the beginning of civilization. What we eat becomes our diet, and our diet plays a major role in deciding how healthy we are and how well our body functions. Without proper diet, our body cannot carry out the functions it needs to perform. Most people have some common knowledge on what is good and what is bad for the human body to consume. Fruits, vegetables, nuts, and grains are some common items people think of when they think of healthy foods. However, it is not enough just to know what foods are good for your body, it is also important to understand why certain foods are good for you and what they do to help the body function.

Obesity can be related to eighty percent of type two diabetes, seventy percent of cardiovascular disease, thirty percent to gall bladder surgeries, and forty two percent to breast and colon cancer.
