Supermarket packaging oftencontains common English wordsthat are oddly confusing. Here’swhat you need to know to safeguardyour health.
Imitation

A food that simulates another foodbut isn’t made of the same stuff isan imitation, right? Not quite. Itshould be labeled imitation only if ithas a lower amount of protein orsome other essential nutrient thanthe food it’s copying.
Free
Packages bearing the words fat-,sugar-, or sodium-free may stillcontain trace amounts of those substances.The FDA evaluates theseterms according to a typical portionsize known as an RACC (referenceamounts customarily consumedper eating occasion). An RACC ofeggnog, for example, is a half cup,and for croutons, it’s 7 g. To belabeled free of calories, a foodshould have fewer than 5 caloriesper RACC; to qualify as fat- or sugarfree,less than 0.5 g per RACC; andto be labeled sodium-free, fewerthan 5 mg per RACC.
Reduced/Less
Don’t be fooled: Just because a product claims to have reduced fat or to contain less sugar doesn’t mean it’s low in the stuff you should avoid in excess(过量). Such terms just mean the amount is lower than usual; the food might not meet the standard for low at all. These phrases indicate a relational claim compared with a reference food. The reduced substance (for example, total fat, sugar, etc.) should be at least 25 percent less per RACC than the amount in an appropriate reference food.
