Yes: Heart and liver disease can occur in someone who eats lots of junk foods, but it is more complicated than just what you eat. It depends upon other risk factors such as cholesterol, smoking, diabetes, hypertension and family history. It is always better to avoid the junk and high sugar foods. If you do this when you are young it will be much better for you when you get older.

Diseases: Have both genetic and environmental causes. It is not as simple as most people think. However reducing risk by eating healthy, no smoking or drugs,reducing stress and exercise will always be beneficial
