A healthy diet is the basis for a well functioning body. Food is the source of energy for all our body functions and directly affects how our bodies and minds function in every stage of life. Just as a little child would define food as what we eat to make us grow.
There are a variety of reasons why a healthy diet is important,including disease prevention, maintenance of a healthy weight and quality of life.

Calories are the unit of measure for stored energy in food. The energy provided by food calories is needed for every function of the body including thought, physical activity, growth,and healing. Proteins Carbohydrates, and the fats are the building blocks of energy.

It aids weight management
While calories are needed for energy, empty calories, those derived from foods with little nutritional value can lead to weight gain. A healthy diet helps maintain an ideal body weight and prevent obesity.When eaten frequently, foods high in saturated fat, trans fat, sugar can lead to excess weight gain. Eating food with a balance of calories and nutrients can help provide the body with the fuel it needs to function while avoiding weight gain.

A poor diet has been directly linked with diseases such as diabetes, heart diseases and certain types of cancer. Trans and saturated fats are known to cause atherosclerosis, which is a major risk factor for heart attack and stroke. Foods that contribute to obesity are also indirectly linked to cancer, since obesity increases the overall risk of developing cancer.
