The best example of how associations influence eating is that we often eatnot because we're hungry but because it's "lunchtime," because foods smell good,or because our friends are eating.

More evidence that associations influence eating comes from marketing andadvertising pressures to sell foods by offering huge servings. For example,movie theaters offer an extra large box of popcorn,and adults learn to prefer large portions and tastyfoods high in fat,sugar,and calories,there has been a corresponding increase inrates of being overweight(from 25% in 1988 to 34% in 1998).Researchers areespecially concerned about the continued rates of overweight and obesity(肥胖) inchildren since childhood obesity is very difficult to treat and an obese childhas a high probability of becoming an obese adult with the associated healthrisks we discussed earlier.

Health professionals suggest that to avoid future increases in rates ofoverweight and obesity, we need to try hard to forget many of our foodassociations, which primarily involves decreasing size of food portions,increasing levels of activity to burn off excess calories.
