Yes, the reasons are scientific. However, most people won't take the time to read all this - because they are SELFISH - all they care about is "WHAT'S IN IT FOR ME NOW"... so, I suggest if you're trying to educate people, just get to the Health part and how it rots and putrefies in their intestines for years, and how it accelerates aging and makes you ugly faster, and makes you fatter, and gives much greater chances of having heart attacks and circulation problems etc.
