I am trying to stop worrying about my teenage son’s addiction to junk food. No matter how easy I make it for him to warm up stuff like spaghetti bolognaise or plates of dinner when we go away, he sticks to cheese and ham, pizzas or toasted sandwiches or pancakes if he is forced to eat at home. If he has money, then it is always a large McDonald’s no. 1 or more pizzas which he gets half-price where he works. What about cholesterol, I whine? Oh, he can take it because he is young and active, scoffs he. He doesn’t eat breakfast. My elder son however, reminded me that he was exactly the same at 18, even to the extent of doing pizza deliveries to earn just enough money to get himself to night clubs and pay his petrol. That was until he took a cholesterol test, aged 20, and got a shock. He changed overnight and today (ten years on) is not only an accomplished cook, but is almost painfully health conscious, to the point where he only buys ‘organic’ foods where possible. I suppose he can afford to. Meanwhile, I worry about No.2 son, who complains that healthy food is so expensive and a schlep to prepare.
