People do learn a lot of habits that stick with them through their lives when they are young. This does make watching what eating habits our children develop early on very important. The effects of taxes on cigarettes in the United States show that it can have an effect on cigarette consumption. American politicians will no doubt be looking at how such a tax directed at junk food fares in the UK and perhaps consider one here. The only problem will be the administration of such a tax. You can bet various manufacturers will be lobbying to have their product not labeled junk food and that their competitors’ products be labeled junk food. Will science determine what gets taxed or will money?
