Watermelon as a potential fruit snack

With the rapid increase in cardiovascular diseases, health-conscious consumers are increasingly showing more interest in foods that provide health benefits beyond the provision of essential nutrients. Watermelon contains phytochemicals such as lycopene, vitamin C, β-carotene, and Total polyphenolic content that possess anti-inflammatory, anticancer, and antioxidant properties. Dietary intake of these products with antioxidants properties is important in maintaining human health and well-being. These reduces incidence of chronic diseases such as hypertension, diabetes, cancer, and some coronary heart diseases, through inhibiting formation of free radicals and reactive oxygen species. The presence of these phytochemicals enhances its potential use as a functional ingredient in food application. This paper aims to characterize the phytochemicals found in watermelon, and emphasis is directed toward the role of natural antioxidants in reducing the risk of chronic diseases to discourage the use of synthetic antioxidants. Moreover, another focus is on seeking the recognition of watermelon as a potential snack and to support its traditional consumption.
