Diseases of affluence are diseases caused mainly by having a lot of wealth, or lots of money. They're caused by being able to buy lots of unhealthy things like processed foods, and not being able to get enough exercise or fresh air. Diseases of affluence can include diabetes, heart disease, obesity, and stroke. They can be dangerous and hard to treat because these diseases can get worse over time if people don't take care of themselves. Eating healthy foods, exercising, and getting enough rest can help prevent and manage these diseases.
