How does food impact health?

In addition to sleep and physical activity, a balanced diet is one of the key elements of health and well-being. Healthy eating not only makes you feel good but also has a variety of physical health benefits. Since food fuels bodily processes, it makes sense that good food encourages optimal overall function. Eat a wide variety of healthy foods, like fruits, vegetables, whole grains and lean protein, for maximum health benefits.

The food we eat gives our bodies the "information" and materials they need to function properly. If we don't get the right information, our metabolic processes suffer and our health declines.
If we get too much food, or food that gives our bodies the wrong instructions, we can become overweight, undernourished, and at risk for the development of diseases and conditions, such as Arthritis, Diabetes, Heart Disease.

The nutrients; i.e. vitamins and minerals, in the food we eat allow the cells in our bodies to perform the necessary physical functions. These nutrients are essential for growth and without them health declines.
When a cell does not regularly receive its requirements, the metabolic processes slow down or even stop.
