Role of Horticultural Crops in Food and Nutritional Security: A Review

Abstract

Horticultural crops perform a very important role in both food and nutritional security more especially in developing countries. Fruit and vegetables have high content of both nutritional and health promoting compounds which consist mostly of essential vitamins, minerals and anti-oxidant that is not present in major staple food crops. Fruits and vegetables supply a large constituent of human nutrition, as they are vital sources of minerals, vitamins, nutrients, dietary fiber, ant-oxidant and phytochemicals that are easy to produce and have short production cycle. A diet rich in fruits and vegetables can help in reducing high blood pressure, lower the risk of heart disease and stroke, provide protection against most types of cancer, reduce the risk of eye and digestive problems, and have a significant effect controlling blood sugar levels which serve as appetite booster. The higher the amount of daily intake of fruits and vegetables, the lower the risk of developing cardiovascular diseases. Fruits and vegetables also contain fiber that assist in bowel movements and can relieve or prevent constipation. Eating fruits and vegetables can also keep eyes healthy and may help prevent two common eye diseases like cataracts and macular degeneration. The FAO, IFAD, UNICEF, WFP and WHO report on state of World food and nutrition security for the year 2021 painted a gloomier picture. The report estimated that between 720 and 811 million people in the world faced hunger in 2020 with close to 2.37 billion people did not have access to adequate food in 2020. Thus the need to encourage the production of horticultural crops can help in enhancing food and nutritional security since it is an enterprise that maximizes small space in terms of value and health benefits.
