Which set of conditions is described as having a strong nutritional component?

• A. Pellagra, Scurvy
• B. Osteoporosis, Osteoarthritis
• C. Iron-Deficiency Anemia
• D. Type 2 Diabetes, Heart Disease, High Blood Pressure, Obesity

Answer: (D)

Nutrition strongly influences the risk and management of several chronic diseases, so the set that includes Type 2 Diabetes, Heart Disease, High Blood Pressure, and Obesity Best illustrates a strong nutritional component. Diet affects body weight, insulin sensitivity, blood sugar control, blood lipid levels, and blood pressure. For example, excess caloric intake and poor dietary patterns can lead to obesity, which raises the risk of insulin resistance and type 2 diabetes. That same weight-related and metabolic dysfunction contributes to high blood pressure and unfavorable cholesterol profiles, increasing heart disease risk. Diets rich in whole foods, fiber, and healthy fats, and lower in added sugars and sodium, can substantially reduce risk and help manage these conditions.

Pellagra and scurvy are classic deficiency diseases driven by specific nutrient shortages (niacin and vitamin C, respectively). They are clearly nutrition-related but represent specific deficiency outcomes rather than a cluster of interconnected chronic conditions. Osteoporosis is strongly affected by nutrition (calcium and vitamin D), but osteoarthritis is more about joint wear and mechanical factors, so nutrition’s role here is less central to the disease set as a whole. Iron-deficiency anemia is a nutrition-related condition, yet it’s a single deficiency rather than a group of conditions linked together by diet.
