The right hon. Gentleman will learn that diet is actually the major factor. I will go on to say a little more about that later. He is right that it is difficult to talk about the subject without seeming like a killjoy, so I will fess up right at the beginning: I enjoy a glass of wine with my meals, although I try to restrict it to weekends; I am martyr to my cravings for chocolate; and, like many of us in this House, I could do with
losing a bit of weight. However, we should not let our own frailties put us off tackling what I believe to be a real health emergency.
I have seen a huge change in diet, particularly in children’s diets, over my lifetime. When I was growing up, pop was a treat that we got occasionally, and we usually got a bottle of it between several of us. Sweets were bought by our dads on payday. If we were out playing—most children did play out in those days—and we came in hungry, we got bread and butter and a drink of water. Now, thanks to a huge change in lifestyle, the wider availability of products and some heavy marketing to children, the situation has changed. Many adults and most of our children are not meeting the proper dietary requirements. We eat too much saturated fat and too much sugar—both added sugar, and sugar in fruit juices, honey and similar products.
