They are not low enough in fat to significantly reduce risk of the fat-related medical conditions. In addition, they use small portion sizes to reduce the total number of calories, so people who eat them often feel unsatisfied and risk bingeing on high-fat items. Increasing consumer demand for nonfat items has filled supermarket shelves with all sorts of seemingly sinful, yet fat-free foods. Now there's fat-free cream cheese made from skim milk. Try nonfat frozen yogurt, or sorbet, made entirely from frozen pureed fruit.
Supermarkets now carry literally hundreds of nonfat items.
The next time you go shopping, open your eyes to the new world of nonfat food alternatives. But nonfat foods are no license to overeat. Some fat-free foods contain modified forms of carbohydrate used as emulsifiers or bulking agents that can push up your blood sugar. Ask your dietitian which ingredients you should watch out for, and how many carbohydrates and calories you should consume in a day, then don't eat more than that number. While eating, don't do anything else.
