Healthy foods have the power to energize you, to prevent disease and to help manage health conditions. Choosing junk food, empty calories and bad fats, such as trans fats, can lead to fatigue, disease and poor quality of life.

Keep the Body Working Well

Healthy, nutrient-dense foods keep the body operating properly because the body is constantly replacing and regenerating all of its cells. Our diet influences how all of our cells grow, from our organs to our blood to our skin. When you eat vitamin- and mineral-rich foods, your cells will grow healthy and strong. Choosing a poor diet leads to cells that are not of optimal quality.

Fight Heart Disease

One of the top weapons for fighting and preventing heart disease is a healthy diet. Your food choices affect cholesterol and blood pressure.

Combat Diabetes

People can prevent or delay the onset of diabetes with a healthful diet. People who are already diabetic can manage their condition and improve quality of life with a healthful diet. People with diabetes have too much glucose in their blood. Eating properly keeps blood glucose levels in check. Left untreated, high blood glucose can lead to kidney issues, eye problems, nerve damage, heart disease and stroke.

Cut Cancer Risk

Healthful food choices, along with exercise, influence the risk of developing cancer. In fact, aside from quitting smoking, the absolute best way to reduce cancer risk is to maintain a healthy weight. Being overweight increases risk for breast cancers in women past menopause, for cancer in the kidney and other organs and for cancer in the esophagus, the colon and the endometrium.

Fight Obesity

Eating properly combats obesity, the second leading cause of unnecessary deaths in the United States. About one-third of the U.S. population, or 60 million people, suffer obesity. Obesity has drastic, negative effects on a person's health.

Improve Athletic Performance

Poor diet has a negative effect on athletic performance--even for casual athletes. To gain the energy needed to enjoy a workout or to complete a competitive sport, an athlete needs adequate calories, protein, vitamins and minerals.
