Vegetables are low in calories and high in vitamins, fiber, and folic acid, making them an important part of a healthy diet. Their low calorie density allows for larger portions without consuming too many calories, promoting satiety and preventing overeating.
The nutritional value of vegetables is generally considered to be very high for a number of reasons. They are naturally low in calories, which means they serve a notable place in a diet geared toward achieving or maintaining a healthy body weight and preventing obesity-related health problems. In addition, they are full of vitamins, such as folic acid and fiber. Combined, all of these elements significantly raise the nutritional value of vegetables.
Vegetables are not considered calorically dense, meaning they contain relatively few calories per serving. The low calorie density is a large contributor to the nutritional value of vegetables because it is possible to eat larger portions, and therefore consume more of the nutrients they offer, without consuming an inappropriately large number of calories. This low caloric value allows people to eat a larger volume of vegetables than they might eat higher calorie foods, promoting satiety without overindulging. Also, greens, like most other vegetables, are naturally low in fat.
While different varieties of vegetables will differ in the amounts of some nutrients they contain, vegetables are generally high in vitamins K, A, and C. Vitamin K is hailed for its ability to help form blood clots that can prevent excessive bleeding in the event of injury or surgery, as well as to promote healthy bone density and play an important role in cardiovascular health. Bone health is also promoted by vitamin A, a nutrient that is also essential for cell development, healthy skin, and the maintenance of mucous membranes and body tissues. Vitamin C, perhaps better known, is most notable for helping the body fight infection and improve immune function, as well as its role in regulating cholesterol levels.
A variety of B vitamins are present in different types of vegetables, but most contain significant amounts of folic acid, or folic acid. Folate is considered an essential nutrient, particularly for women of childbearing age, because it plays a crucial role in preventing neural tube defects in newborns. Given this important health benefit, the presence of folic acid undoubtedly impacts the nutritional value of vegetables.
Fiber is another important element of the overall nutritional value of vegetables. Vegetables like greens are one of the most prominent sources of dietary fiber, which is essential for healthy digestive function. Consuming dietary fiber also produces feelings of fullness and satiety, which can help prevent overeating.
