Nutritional value and health benefits of horticulture.

Abstract

Abstract Daily consumption of fruit and vegetables is encouraged as important for human health and nutrition because the vitamins, minerals, essential micronutrients, fibre, vegetable proteins and bio-functional components they provide are crucial for bodily function. The FAO/WHO expert consultation (2004) on diet, nutrition and the prevention of chronic diseases recommended a daily intake of 400 g (five portions) of fruits and vegetables (excluding potatoes and other starchy tubers) to prevent heart disease, cancer, diabetes and obesity. However, despite this recognition, world-wide per capita consumption of fruits and vegetables is estimated to be 20-50% short of the minimum recommended level. In 2013 an estimated 5.2 million deaths worldwide were attributable to inadequate fruit and vegetable consumption. Adhering to the WHO recommendations for fruit and vegetable intake can prevent morbidity and mortality caused by micronutrient deficiencies, birth defects, mental and physical retardation, weakened immune systems, blindness and even death. Improving the dietary diversity through horticulture-based food intake is an effective and sustainable approach to combating micronutrient malnutrition in both developed and developing countries (Kennedy et al., 2003).
