What it means: This means that a product does not have any of that nutrient, or so little that it’s unlikely to make any difference to your body. For example, “calorie-free” means less than 5 calories per serving. “Sugar-free” and “fat-free” both mean less than 0.5 g (grams) per serving.

Is calorie free really calorie free?

Nothing you put in your mouth, chew, and swallow is completely free, it turns out. Per the FDA, manufacturers are allowed to say a food is calorie-free if a serving is less than five calories.

Does zero calories mean sugar free?

Coke Zero does not contain any calories or sugar and is not a significant source of nutrients. It’s sweetened with artificial sweeteners, which have controversial health effects.
