Calorie charts are helpful for individuals who are monitoring their overall caloric intake or trying to reduce calories. Vegetables are naturally low in calories, but it may be helpful to compare the calories in a serving of vegetables versus a serving of higher-calorie foods.
Research shows that individuals who track calorie intake are more likely to be successful at losing weight than those who don't. Many calorie counters offer additional nutritional information about foods, such as vitamins and mineral content. Individuals trying to manage or reduce the risk of chronic conditions, such as heart disease, Type 2 diabetes and obesity, may monitor dietary fiber intake as part of a heart-healthy diet. Fiber also reduces blood cholesterol, constipation and diverticulosis. Additionally, vegetables with high fiber content increase feelings of satiety with fewer calories.
A person can also monitor potassium levels, which lower blood pressure, decrease bone loss and reduce the risk of kidney stones. Folate, or folic acid, is found in a variety of vegetables and is particularly important for women of childbearing age because it supports the production of red blood cells. Additionally, nutritional counters help individuals track foods with vitamin A, which supports skin health, and vitamin C, which aids in iron absorption, promotes healthy teeth and gums, and helps to heal cuts and wounds.
