Malnutrition refers to deficiencies, excesses or imbalances in a person’s intake of energy and/or nutrients. The term malnutrition covers ‘undernutrition’ – which includes an overall lack of food, resulting in stunting (low height for age) and/or wasting (low weight for height), as well as a lack of diverse and nutritious food, resulting in micronutrient deficiencies (a lack of important vitamins and minerals). Malnutrition also includes overweight and obesity, resulting in diet-related noncommunicable diseases (such as heart disease, stroke and diabetes) (WHO).
