As at all times, vegetables play an important role in human nutrition, especially as sources of vitamins (C, A, B6, E, thiamine, niacin), minerals and dietary fiber. Their contribution as one of the food groups in the total weight is estimated at 91% vitamin C, 48% vitamin A, 27% vitamin B6, 17% thiamine, 15% niacin. Vegetables also provide 16% of magnesium, 19% of iron, and 9% of calories. Legumes and potatoes make up about 5% of protein, which in turn contains essential amino acids. Vegetables include folic acid, riboflavin, zinc, calcium, potassium, and phosphorus.

Climatic conditions, especially temperature and light intensity, have a strong influence on the quality of vegetables, as well as the soil in which they grow. Cultural practices show that the condition of vegetables and the amount of their nutrients depend on water, maturity at harvest, harvesting method, delay between harvest and consumption. The amount of taste loss increases with exposure to temperature, relative humidity, and carbon dioxide concentrations that are optimal for each product. In addition, the processing and cooking methods can significantly affect the nutritional value of vegetables.

If vegetables are present in your daily diet, then the risk of developing certain forms of cancer, cardiovascular diseases, stroke and other chronic diseases decreases. Some components of vegetables are strong anti-oxidants, capable of altering metabolic activation, detoxification, the amount of carcinogens, or even affecting processes in tumor cells. Although the antioxidant potential varies depending on the type of vegetable. In some countries, people are advised to eat up to 10 servings of vegetables per day. There is increasing evidence that consuming whole vegetables is better than their individual components.

Examples of vegetables that have a positive effect on human health and their important sources are given below.:
Vitamin C: broccoli, cabbage, melon, pepper, potatoes, tomatoes.

Vitamin A: dark green vegetables (such as cabbage, spinach (carotenoids), turnips, orange vegetables (such as pumpkin and carrots), tomatoes, sweet potatoes.

Fiber: all fresh vegetables, dried beans and peas.

Folic acid: Dark green leafy vegetables (such as spinach, mustard, and lettuce).

Potassium: baked potatoes or sweet potatoes.

It is noted that vegetables and fruits have almost the same nutritional properties. About 70 percent or more of their weight consists of water, they provide relatively few calories and protein, but many of them contain vitamin C and carotene. However, boiled vegetables are an uncertain source of vitamin C, as this vitamin is easily destroyed by heat treatment. Vegetables in the human diet are a source of calcium and iron, but often in a form that is poorly absorbed. Vegetables also contain fiber, which is added to the contents of the intestine and is used to prevent constipation.
