Frequently Asked Questions
How accurate are nutrition labels?
FDA regulations allow a 20% margin of error for labeled nutrient values. Actual calorie content may be higher or lower than stated. This margin matters less for whole foods with single ingredients and more for processed foods with many components.
Why do serving sizes seem so small?
Serving sizes are set by the FDA based on reference amounts customarily consumed, not necessarily healthy portions. However, some manufacturers strategically choose smaller servings to make nutrition stats look better. The 2016 label update adjusted some serving sizes to be more realistic.
What if a food does not have a nutrition label?
Fresh produce, raw meat, and foods from small manufacturers may be exempt from labeling requirements. Use nutrition databases like ours to find nutrition information for unlabeled foods. Restaurant foods are increasingly required to display calories in chain establishments.
Should I count total carbs or net carbs?
It depends on your goals. Total carbs matter for diabetes management and strict carb counting. Net carbs (total carbs minus fiber) may be more relevant for keto diets and understanding blood sugar impact, though this approach is debated among nutrition professionals.
