In an era when everyone is concerned about health, "health" and "keeping in good health" are relatively easy to gain recognition. Some merchants know their way well, so they have launched cookies with various additional functions. In fact, the US Food and Drug Administration has explicitly prohibited this kind of behavior. According to the provisions of the Food Safety Law, ordinary food shall not publicize or imply the function of treating or preventing diseases. Frankly speaking, functional cookies are not reliable.
In fact, the ingredients of food sold in the market are not very reliable, and it is also well-founded to say that it is junk food. Everything produced by large commercial factories for profit is always suspicious.
