Diet patterns
How these tags are decided
Foods are tagged high protein when at least 20% of their energy comes from protein, the threshold set by the European Union for a high-protein claim (Regulation (EC) No 1924/2006). Foods are tagged keto-friendly or low carb when they contain at most 5 g or 10 g of total carbohydrate per 100 g. Ketogenic and low-carbohydrate eating patterns limit total daily carbohydrate (commonly 20 to 50 g per day for ketogenic diets, and under about 130 g per day for low-carb diets), so foods low in carbohydrate per 100 g fit within that budget. These per-100-gram cut-offs are Vitals Hub's own thresholds, chosen to reflect those daily budgets; they are not a regulatory or clinical standard. All values are USDA-sourced totals per 100 g.
