Sugar as poison

Yesterday I read something that offered another explanation as to why eating added (as opposed to naturally occurring) sugars is dangerous for health (i.e. apart from spiking insulin and leading to insulin resistance). It is an extract from a well-known book called Sugar Blues by William Dufty © 1975. I don't have the entire text but this is the extract I read:

"In 1957, Dr. William Coda Martin tried to answer the question: When is a food a food and when is it a poison? His working definition of "poison" was: "Medically: Any substance applied to the body, ingested or developed within the body, which causes or may cause disease. Physically: Any substance which inhibits the activity of a catalyst which is a minor substance, chemical or enzyme that activates a reaction."1 The dictionary gives an even broader definition for "poison": "to exert a harmful influence on, or to pervert".

Refined Sugar

Dr. Martin classified refined sugar as a poison because it has been depleted of its life forces, vitamins and minerals. "What is left consists of pure, refined carbohydrates. The body cannot utilize this refined starch and carbohydrate unless the depleted proteins, vitamins and minerals are present. Nature supplies these elements in each plant in quantities sufficient to metabolize the carbohydrate in that particular plant. There is no excess for other added carbohydrates. Incomplete carbohydrate metabolism results in the formation of 'toxic metabolite' such as pyruvic acid and abnormal sugars containing five carbon atoms. Pyruvic acid accumulates in the brain and nervous system and the abnormal sugars in the red blood cells. These toxic metabolites interfere with the respiration of the cells. They cannot get sufficient oxygen to survive and function normally. In time, some of the cells die. This interferes with the function of a part of the body and is the beginning of degenerative disease."2

Refined sugar is lethal when ingested by humans because it provides only that which nutritionists describe as "empty" or "naked" calories. It lacks the natural minerals which are present in the sugar beet or cane.

In addition, sugar is worse than nothing because it drains and leaches the body of precious vitamins and minerals through the demand its digestion, detoxification and elimination makes upon one's entire system. So essential is balance to our bodies that we have many ways to provide against the sudden shock of a heavy intake of sugar. Minerals such as sodium (from salt), potassium and magnesium (from vegetables), and calcium (from the bones) are mobilized and used in chemical transmutation; neutral acids are produced which attempt to return the acid-alkaline balance factor of the blood to a more normal state.

Sugar taken every day produces a continuously overacid condition, and more and more minerals are required from deep in the body in the attempt to rectify the imbalance. Finally, in order to protect the blood, so much calcium is taken from the bones and teeth that decay and general weakening begin. Excess sugar eventually affects every organ in the body. Initially, it is stored in the liver in the form of glucose (glycogen). Since the liver's capacity is limited, a daily intake of refined sugar (above the required amount of natural sugar) soon makes the liver expand like a balloon. When the liver is filled to its maximum capacity, the excess glycogen is returned to the blood in the form of fatty acids. These are taken to every part of the body and stored in the most inactive areas: the belly, the buttocks, the breasts and the thighs.

When these comparatively harmless places are completely filled, fatty acids are then distributed among active organs, such as the heart and kidneys. These begin to slow down; finally their tissues degenerate and turn to fat. The whole body is affected by their reduced ability, and abnormal blood pressure is created. The parasympathetic nervous system is affected; and organs governed by it, such as the small brain, become inactive or paralyzed. (Normal brain function is rarely thought of as being as biologic as digestion.) The circulatory and lymphatic systems are invaded, and the quality of the red corpuscles starts to change. An overabundance of white cells occurs, and the creation of tissue becomes slower. Our body's tolerance and immunizing power becomes more limited, so we cannot respond properly to extreme attacks, whether they be cold, heat, mosquitoes or microbes.

Excessive sugar has a strong mal-effect on the functioning of the brain. The key to orderly brain function is glutamic acid, a vital compound found in many vegetables. The B vitamins play a major role in dividing glutamic acid into antagonistic-complementary compounds which produce a "proceed" or "control" response in the brain. B vitamins are also manufactured by symbiotic bacteria which live in our intestines. When refined sugar is taken daily, these bacteria wither and die, and our stock of B vitamins gets very low. Too much sugar makes one sleepy; our ability to calculate and remember is lost."
