Why is eating healthy important?

The nutrients in the foods you eat support the activities of day-to-day living, protect your cells from environmental damage and repair any cellular damage that might occur. Protein rebuilds injured tissue and promotes a healthy immune system. Both carbohydrates and fats fuel your body, while vitamins and minerals function throughout your body in support of your body’s processes. Vitamins A, C and E, for example, act as antioxidants to protect your cells against toxins, and B vitamins help you extract energy from the foods you eat. Calcium and phosphorus keep your bones strong, while sodium and potassium help to transmit nerve signals. Without a healthy diet, you might compromise any of these essential functions.

In addition to the quality of the foods you consume, the quantity matters when considering good eating habits. Taking in the same number of calories as you burn ensures your weight remains steady over time. Consuming more than you burn, on the other hand, results in weight gain as your body converts extra calories to fat tissue. When you accumulate fat tissue, you increase your risk of developing one or more health problems, including heart disease, hypertension, respiratory issues, diabetes and cancer. A healthy meal plan without excess calories helps you not only feel better but can prolong your life.

Obesity is not the only nutrition-related cause of disease onset and progression. Too much or too little of certain nutrients can also contribute to health issues. For instance, a lack of calcium in your diet can predispose you to developing osteoporosis, or weakening of your bones, while too much saturated fat can cause cardiovascular disease, and too few fruits and vegetables in your nutrition plan is associated with an increased incidence of cancer. Consuming foods from a wide variety of sources helps ensure your body has the nutrients it needs to avoid these health problems.

If you are not used to eating a healthy diet that promotes your well-being, making gradual changes can help you improve the way you eat in the long run. You can substitute water for high-calorie, sugary drinks, for example, and switch from full-fat to low-fat dairy products. Selecting lean meats instead of fatty cuts and whole-wheat grains instead of refined grains can lower your intake of unhealthy fats and increase your dietary fiber intake. Fresh fruits and vegetables contain less sodium than canned, and snacking on fresh, crunchy produce like carrots, apples and cucumber slices is healthier than the fats and salt in chips.
