Review Questions

• How does nutrition serve as a risk factor in the development of chronic diseases?
  • Nutrition is a key risk factor in chronic disease development because poor dietary habits can lead to conditions like obesity, heart disease, and type 2 diabetes. Diets high in processed foods, sugars, and unhealthy fats increase the likelihood of these diseases. Conversely, a diet rich in fruits, vegetables, whole grains, and lean proteins helps to mitigate these risks by promoting better metabolic health and reducing inflammation.
