���Light��� claims
(b) Light claims. The terms light or lite may be used on the label or in labeling of products, except meal-type products as defined in 381.413(l) and main-dish products as defined in 381.413(m), without further qualification, provided that: (1) If the product derives 50 percent or more of its calories from fat, its fat content is reduced by 50 percent or more per reference amount customarily consumed compared to an appropriate reference product as described in 381.413(j)(1); or (2) If the product derives less than 50 percent of its calories from fat: (i) The number of calories is reduced by at least one-third (33 1/3 percent) per reference amount customarily consumed compared to an appropriate reference product as described in 381.413(j)(1); or (ii) Its fat content is reduced by 50 percent or more per reference amount customarily consumed compared to the appropriate reference product as described in 381.413(j)(1); and (3) As required in 381.413(j)(2) for relative claims: (i) The identity of the reference product and the percent (or fraction) that the calories and the fat were reduced are declared in immediate proximity to the most prominent such claim (e.g., 1/3 fewer calories and 50 percent less fat than the market leader); and (ii) Quantitative information comparing the level of calories and fat content in the product per labeled serving size with that of the reference product that it replaces is declared adjacent to the most prominent claim or to the nutrition information (e.g., lite this product200 calories, 4 grams (g) fat; regular reference product300 calories, 8 g fat per serving); and (iii) If the labeled product contains less than 40 calories or less than 3 g fat per reference amount customarily consumed, the percentage reduction for that nutrient need not be declared. (4) A light claim may not be made on a product for which the reference product meets the definition of low fat and low calorie.
