Why Are Vegetables Important To The Human Body?

"Eat your vegetables!" It's an order you've probably heard all your life, since Mom was serving a portion of broccoli with your meatloaf or macaroni and cheese. Now it's the medical experts who encourage you to add more vegetables to your diet, for example, The American Cancer Society recommends at least five servings of fruits and vegetables a day for good health. The Harvard School of Public Health goes further, recommending nine servings of vegetables and fruits a day. This is enough to make you wonder exactly why vegetables are so important for human health.

Vitamins and antioxidants

One of the main benefits of vegetables over health is their high nutrient content. Vegetables are rich in vitamins and minerals that contribute to growth and maintain good health. For example, The U. S. Department of Agriculture indicates that many vegetables are rich in potassium, which is an important element in having a healthy blood pressure. Several vitamins, such as A and C, help keep eyes, skin, teeth and gums healthy, fight infections and promote wound healing. Perhaps most important, vegetables are rich in a particular group of nutrients called antioxidants, which fight cell damage and help prevent heart disease, cancer, Parkinson's disease, arteriosclerosis, heart attacks and disease. of Alzheimer's, indicates The Linus Pauling Institute.

Fiber

Another important benefit of vegetables is dietary fiber. Fiber is an important nutrient found only in foods of plant origin. As part of a healthy diet, fiber helps eliminate bad cholesterol from your arteries, reducing your risk of heart disease, says USDA. Fiber also keeps your digestive system in good working order and can help prevent cancer.

Useful characteristics for a diet

Vegetables are also a great help for people who are dieting. Since they are generally low in fat and calories, you can consume many vegetables without gaining weight. If you substitute other high-calorie foods for vegetables in your diet you can reduce your calorie and fat intake, making it easier to control your weight. The fiber in vegetables also helps you control your weight. Fiber makes you feel fuller for a longer period, which helps you eat less in general and lose weight or keep it off.

Considerations

Some vegetables are healthier than others. The Harvard School of Public Health indicates that potatoes (potatoes), which many people consider to be vegetables, do not really count as part of your recommended daily serving of vegetables.Instead, potatoes, and often corn (corn), are starchy foods more like a grain serving than a vegetable one. When choosing vegetables keep in mind that in general, those with bright colors are richer in nutrients than the less vivid color options. For example, spinach contains a much higher amount of vitamins and antioxidants than an iceberg lettuce. If you have questions or concerns related to your diet or vegetables to have good health, consult your doctor or a registered dietitian for more recommendations.
