sugar and your health

Sugar's effect on your health
(from http://www.healingdaily.com/detoxification-diet/sugar.htm )
The average American consumes an astounding 2-3 pounds of sugar each week, which is not surprising considering that highly refined sugars in the forms of sucrose (table sugar), dextrose (corn sugar), and high-fructose corn syrup are being processed into so many foods such as bread, breakfast cereal, mayonnaise, peanut butter, ketchup, spaghetti sauce, and a plethora of microwave meals.

In the last 20 years, we have increased sugar consumption in the U.S. 26 pounds to 135 lbs. of sugar per person per year! Prior to the turn of this century (1887-1890), the average consumption was only 5 lbs. per person per year! Cardiovascular disease and cancer was virtually unknown in the early 1900's.

The "glycemic index" is a measure of how a given food affects blood-glucose levels, with each food being assigned a numbered rating. The lower the rating, the slower the absorption and digestion process, which provides a more gradual, healthier infusion of sugars into the bloodstream. On the other hand, a high rating means that blood-glucose levels are increased quickly, which stimulates the pancreas to secrete insulin to drop blood-sugar levels. These rapid fluctuations of blood-sugar levels are not healthy because of the stress they place on the body.

One of sugar's major drawbacks is that it raises the insulin level, which inhibits the release of growth hormones, which in turn depresses the immune system. This is not something you want to take place if you want to avoid disease.

An influx of sugar into the bloodstream upsets the body's blood-sugar balance, triggering the release of insulin, which the body uses to keep blood-sugar at a constant and safe level. Insulin also promotes the storage of fat, so that when you eat sweets high in sugar, you're making way for rapid weight gain and elevated triglyceride levels, both of which have been linked to cardiovascular disease. Complex carbohydrates tend to be absorbed more slowly, lessening the impact on blood-sugar levels.
Sugar depresses the immune system.

We have known this for decades. It was only in the 1970's that researchers found out that vitamin C was needed by white blood cells so that they could phagocytize viruses and bacteria. White blood cells require a 50 times higher concentration inside the cell as outside so they have to accumulate vitamin C.
There is something called a "phagocytic index" which tells you how rapidly a particular macrophage or lymphocyte can gobble up a virus, bacteria, or cancer cell. It was in the 1970's that Linus Pauling realized that white blood cells need a high dose of vitamin C and that is when he came up with his theory that you need high doses of vitamin Cicon to combat the common cold.

We know that glucose and vitamin C have similar chemical structures, so what happens when the sugar levels go up? They compete for one another upon entering the cells. And the thing that mediates the entry of glucose into the cells is the same thing that mediates the entry of vitamin C into the cells. If there is more glucose around, there is going to be less vitamin C allowed into the cell. It doesn't take much: a blood sugar value of 120 reduces the phagocytic index by 75%. So when you eat sugar, think of your immune system slowing down to a crawl.

Here we are getting a little bit closer to the roots of disease. It doesn't matter what disease we are talking about, whether we are talking about a common cold or about cardiovascular disease, or cancer or osteoporosis, the root is always going to be at the cellular and molecular level, and more often than not insulin is going to have its hand in it, if not totally controlling it.

The health dangers which ingesting sugar on an habitual basis creates are certain. Simple sugars have been observed to aggravate asthma, move mood swings, provoke personality changes, muster mental illness, nourish nervous disorders, deliver diabetes, hurry heart disease, grow gallstones, hasten hypertension, and add arthritis.

Because refined dietary sugars lack minerals and vitamins, they must draw upon the body's micro-nutrient stores in order to be metabolized into the system. When these storehouses are depleted, metabolization of cholesterol and fatty acid is impeded, contributing to higher blood serum triglycerides, cholesterol, promoting obesity due to higher fatty acid storage around organs and in sub-cutaneous tissue folds.

Because sugar is devoid of minerals, vitamins, fiber, and has such a deteriorating effect on the endocrine system, major researchers and major health organizations (American Dietetic Association and American Diabetic Association) agree that sugar consumption in America is one of the 3 major causes of degenerative disease.

Honey is a simple sugar

There are 4 classes of simple sugars which are regarded by most nutritionists as "harmful" to optimal health when prolonged consumption in amounts above 15% of the carbohydrate calories are ingested: Sucrose, fructose, honey, and malts.
Some of you may be surprised to find honey here. Although honey is a natural sweetener, it is considered a refined sugar because 96% of dry matter are simple sugars: fructose, glucose and sucrose. It is little wonder that the honey bear is the only animal found in nature with a problem with tooth-decay (honey decays teeth faster than table sugar). Honey has the highest calorie content of all sugars with 65 calories/tablespoon, compared to the 48 calories/tablespoon found in table sugar. The increased calories are bound to cause increased blood serum fatty acids, as well as weight gain, on top of the risk of more cavities.
sugar and honey

Pesticides used on farm crops and residential flowers have been found in commercial honey. Honey can be fatal to an infant whose immature digestive tracts are unable to deal effectively with Botulinum Spore growth. What nutrients or enzymes raw honey does contain are destroyed by manufacturers who heat it in order to give it a clear appearance to enhance sales. If you are going to consume honey, make sure it is raw, unheated honey. Good to use in special cures, but not as an every day food. It is not much better than white or brown sugar.

Sugar and cancer

Of the over 4 million cancer patients being treated in the U.S. today, almost none are offered any scientifically guided nutrition therapy other than being told to "just eat good foods." Many cancer patients would have a major improvement in their conditions if they controlled the supply of cancer's preferred fuel: GLUCOSE. By slowing the cancer's growth, patients make it possible for their immune systems to catch up to the disease. Controlling one's blood-glucose levels through diet, exercise, supplements, meditation and prescription drugs - when necessary - can be one of the most crucial components to a cancer treatment program. The saying "Sugar feeds cancer" is simple. The explanation is a little more involved.
German Otto Warburg, Ph.D., the 1931 Nobel laureate in medicine, first discovered that cancer cells have a fundamentally different energy metabolism compared to healthy cells. The gist of his Nobel thesis was this: malignant tumors frequently exhibit an increase in "anaerobic glycolysis" - a process whereby glucose is used by cancer cells as a fuel with lactic acid as an anaerobic by-product - compared to normal tissues.(1) The large amount of lactic acid produced by this fermentation of glucose from the cancer cells is then transported to the liver. This conversion of glucose to lactate creates a lower, more acidic PH in cancerous tissues as well as overall physical fatigue from lactic acid build-up.(2,3) Therefore, larger tumors tend to exhibit a more acidic PH.(4)
anaerobic glycolysis

Hence, cancer therapies should attempt to regulate blood-glucose levels through diet, supplements, exercise, medication when necessary, gradual weight loss and stress reduction. Since cancer cells derive most of their energy from anaerobic glycolysis, the goal is not to eliminate sugars or carbohydrates entirely from the diet but rather to control blood-glucose within a narrow range to help starve the cancer cells and boost immune function.
