Actually, it is 100% the same. Your body really cannot tell the difference if fructose is made by a corn plant, a flower, an agave plant, or by an apple. And matter doesn't have any magical properties that we haven't found yet.
Don’t be so sure that we have found everything or know even close to anything. The very “reality” our minds can perceive is such a small piece of the Universe’s big picture. Imagine the limitation of looking at a 100 foot mural through one pinhole at a time. Then multiply that by infinity. That is how much we can “see” right now. The human race is likely to be extinct before we even truly understand 1%.
