Global Food Labeling Laws: US vs EU

Why Labeling Differences Matter

Keto dieters must navigate complex ingredient lists, which vary significantly between regions. In the United States, the FDA mandates clear disclosure of macronutrients, added sugars, and common allergens. However, some additives and artificial sweeteners may be listed under generic names, making it challenging for consumers to identify non-keto ingredients².

In contrast, the European Union, under EFSA oversight, enforces stricter rules on ingredient transparency, including mandatory E-number disclosures and comprehensive allergen labeling. This means a product labeled “keto” in the US may contain ingredients not permitted for keto dieters in the EU.

For frequent travelers or online shoppers, food label scanner apps like Food Scan Genius automatically adjust analysis based on local regulations, ensuring accurate keto compliance worldwide.

AI and NLP: The Future of Food Label Scanning

Recent advances in AI, such as Google’s MUM and Gemini, have revolutionized how apps interpret food labels. These technologies use entity-based natural language processing to understand context, identify synonyms (e.g., “maltodextrin” as a hidden carb), and support voice-activated queries for hands-free shopping³.

Today’s leading apps deliver spoken explanations, highlight risks, and suggest alternatives—all optimized for mobile screens. This ensures that users, including those with visual impairments, can make safe, informed choices.
