What best describes food intolerance is that the body has a negative reaction to a food, but the immune system is NOT involved.

Explanation:

Food intolerance involves the inability of the digestive system to process any nutrients, which can cause symptoms related to the organs of this system. In this case, the body makes a negative reaction to the consumption of some foods, limited to the digestive system.

The difference between food intolerance and an allergic reaction is that the latter involves the immune system, which perceives a food as foreign or harmful, triggering a hypersensitivity reaction that can cause severe symptoms.

An example of food intolerance is lactose intolerance, which occurs due to a deficiency of the enzyme lactase, causing symptoms such as abdominal pain, flatulence and diarrhea.
