Step-by-step explanation:
Both undernutrition and overnutrition can occur in individuals. Undernutrition refers to a lack of nutrients and insufficient energy supply, resulting in people being underweight and experiencing growth failure. Overnutrition, on the other hand, is characterized by excessive nutrient and energy intake, leading to individuals becoming overweight or obese. Obesity is associated with various health problems such as cardiovascular disease, type 2 diabetes, and certain types of cancer.
