Chronic diseases are often influenced by modifiable risk factors. Epidemiological studies have shown that poor diet, lack of exercise, and smoking are significant contributors to the development of conditions like coronary heart disease, type 2 diabetes, and certain cancers. By promoting healthier lifestyles, the incidence of these diseases can be significantly reduced. For example, the Diabetes Prevention Program demonstrated that lifestyle changes could reduce the risk of developing type 2 diabetes by 58% in high-risk individuals.
