The best example of how associations influence eating is that we often eat not 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 and advertising pressures to sell foods by offering huge servings. For example, movie theaters offer an extra large box of popcorn(爆玉米花)，which, at almost 900 calories, is equivalent to a major meal. Health professionals warn that as children, adolescents(青少年),and adults learn to prefer large portions and tasty foods high in fat,sugar,and calories,there has been a corresponding increase in rates of being overweight(from 25% in 1988 to 34% in 1998).Researchers are especially concerned about the continued rates of overweight and obesity(肥胖) in children since childhood obesity is very difficult to treat and an obese child has a high probability of becoming an obese adult with the associated health risks we discussed earlier.
Health professionals suggest that to avoid future increases in rates of overweight and obesity, we need to try hard to forget many of our food associations, which primarily involves decreasing size of food portions, increasing levels of activity to burn off excess calories.

overweight was almost _ during the ten years from 198 to 1998.
[A]10 per cent [B]20 per cent
