I really do not know what your issue is, or where you are coming from.
The definition of saturated and unsaturated fat really is not a matter of controversy. The definition that I initially stated is actually used by scientists. Since this is a public forum, and not a biochemistry forum, I kept the definition at a level where ordinary people can understand it.
Perhaps you think I was making a statement on the consumption of saturated or unsaturated fats? Be assured, I was not—I neither expressed nor implied an opinion on that.
