The food nutrition label does not include the source of nutrients.

The so-called food nutrition label is to mark the nutritional ingredients and display nutritional information on the outer packaging of food, as well as appropriate nutritional claims and health statements. Generally speaking, food nutrition labels include three parts: nutritional ingredients (nutritional information), nutritional claims and health statements. General food labels only indicate nutrients, and food nutrition labels must indicate the content of nutrients and their percentage in daily intake, which is nutritional information.

Nutrition label refers to the sign describing the heat energy and nutrient content of meat, fruits, vegetables and other processed foods.

According to the standard, both prepackaged foods and prepackaged foods for special dietary uses can claim (label) the physiological effects of nutrients on human body on food labels. However, we can only claim the physiological function of a certain nutrient on human body, and we can't claim or imply that it has the function of curing, treating or preventing diseases. "We can't claim that the product itself has the function of a certain nutrient", which is to draw a clear line with health food.
