Type 2 diabetes is becoming increasingly common in the United States. The primary risk factor for type 2 diabetes is a history of obesity. Statistics show that children are becoming obese at an alarmingly high rate, and this correlates with increased rates of type 2 diabetes. When young children become overweight, the problem is usually blamed on nutrition and exercise choices made by the parents. Why do you think today's parents have a harder time feeding their children nutritious meals and providing an exercise program than did parents of previous generations? What can be done to solve this problem? Recently, several families have filed legal action against a fast-food restaurant chain, claiming that their children are obese because they ate there frequently. These parents claim that the restaurant chain is liable because it made the parents think that the food was healthy and would not contribute to obesity. Do you believe that these parents have a case? Explain your response.
