"Never stick anything man-made in your mouth", says Jack LaLane, health and fitness expert.
In the many years that man has inhabited the planet, he has figured out a way to gather up, separate, and put into single boxes, everything he knows of. That is fine. It becomes a problem to every living organism when man keeps collecting to the point of toxicity.
Fact is, it is literaly impossible for man to keep abreast of the infinite changes in nature. And for that reason alone, man should not even attempt. All that comes from the soil of this planet, inevitably returns to the soil of the planet.
An example of this is an orange. An orange is a healthy food in its natural state. Man has taken this food, and again, highly concentrated this food to a toxic state for the human body. This is done by extracting the juices from the orange. If you have enough oranges, one can make a glass of orange juice. You may think, MMMMM delicious. Fact is, you may be getting four,five,six times the amount of sugar than your body needs. This delicious concoction is in reality, very toxic to the body, in particular, the pancreas. Overworking the pancreas with high blood sugars can lead to Diabetes and/or overweight conditions.
