Importance of Nutrition in Health Promotion

Food choices can affect an individual’s overall health, including how they feel today and in the future. It is estimated that about 33.8 percent of U.S. adults and 17.5 percent of children are obese, a condition that has been brought about by poor nutrition habits. Obese people are also prone to type 2 diabetes and heart disease among their chronic conditions. For individuals to protect themselves from such health problems, they need to start making smart food choices thus avoid developing obesity. Indeed, combined with physical activity, good nutrition can reduce an individual’s risk for chronic diseases (Wahl, 2019). It can also help an individual maintain a healthy weight.

Nutritional Challenges for Emerging Populations

Various nutritional challenges such as undernutrition and diet-related chronic diseases are reported to affect the emerging populations across the world. Undernutrition largely prevents people from realizing their full potentials. For instance, children who are affected by this nutritional challenge often underperform in school and this limits them from securing better-paying jobs in the future. Moreover, malnourished adults usually find it hard to work, improve their economy and provide for their families. Besides, undernutrition often increases the risk of diet-related chronic diseases such as cancer and obesity. For an individual to grow properly and live longer, they need to take healthy diets.

Roles Nutritional Excess and Nutritional Deficiencies Play in Disease

Nutritional excess and deficiency are both related to diseases. Nutritional excess can result in chronic inflammatory diseases, such as cardiovascular disease, particularly when an individual maintains a diet with refined carbohydrates and saturated fats coupled with physical inactivity (Owczarek et al., 2016). On the other hand, nutritional deficiency can weaken an individual’s immune function and lead to classical conditions, such as depression.
