Question: are low fat foods high in sugar?
Answer: On the basis of the information collected by the USDA, we found that the amount of sugar is higher in the low-fat (that is, reduced calorie, light, low fat) and non-fat than regular versions of tested items (Friedman P=0.00001, Wilcoxon P=0.0002 for low-fat vs regular food and P=0.0003 for non-fat vs regular food).
