Why Food Label Scanning Matters for Keto (and Everyone Else!)
Food labels are supposed to make life easier, but let’s be honest: they often do the opposite. With over 10,000 food additives approved by the FDA[1] and new “keto-friendly” marketing popping up daily, it’s easy to get lost. For anyone following a ketogenic diet, the stakes are even higher—one hidden carb can kick you out of ketosis faster than you can say “net carbs.”
- Hidden Sugars: Ingredients like dextrose, maltodextrin, and agave can spike blood sugar.
- Artificial Additives: Many “low-carb” foods use fillers or sweeteners that may impact gut health (PubMed[2]).
- Allergens & Sensitivities: Gluten, dairy, and soy can lurk in unexpected places.
And it’s not just keto dieters who care. People with diabetes, food allergies, or anyone striving for clean eating benefit from knowing exactly what’s in their food. That’s where the magic of food label scanner apps comes in!
