that require these substances, although it has numerous uses. First, and most importantly, sugar, as glucose levels in out blood is extremely toxic. Left in our bloodstream without control elevated sugar levels would kill us quickly, so the powerful release of insulin helps keep our blood cleared of excess glucose. Unfortunately insulin is a double-edged sword. Excess sugar in our body cannot be disposed of in an unlimited number of ways. With our increasing sedentary lifestyles refusing to burn off much of this sudden and quick release of carbohydrate as we consume, sugar is rapidly converted to the same saturated fats we are constantly warned about. (As you can see, limiting saturated fat in the diet does not prevent us from accumulating fat in our bodies)
Sugar has other unpleasant side effects. The constantly elevated insulin levels can eventually lead to decreased insulin sensitivity (Syndrome X) and another case of Type II diabetes. Sugar also has an effect on cortisol and our adrenal glands. It causes an excess of these hormones leading to symptoms of stress and fatigue. Sugar also competes with the glucose carriers in our blood, which work with vitamins like Vitamin C, causing disruption to our preciously balanced immune system and causing premature ageing of the skin.
Sugar can be thought of as nitro-fuel for the body. It releases a very quick but harsh burst of artificial energy. In active individuals requiring peak performance from athletic pursuits, simple carbohydrates can be a useful tool, especially in the area of pre and post workout drinks. Much like a drag-racer using nitro fuel, this substance can be used to replace muscle glycogen and spare muscle wastage due to overtraining effects. Unfortunately few of us use sugar in this careful and controlled manner and are attempting to drive the finely balanced engines of our bodies on a fuel which causes too much stress and strain on a system that was never designed to handle the excess we provide.
So since low-carb diets almost completely eliminate sugar from our diets, we have already found one significant health benefit.
GRAIN CONTROVERSY
Most of our Western

Governments offer health guidelines which ask us to base our food intake almost universally around grain-type carbohydrates, what were once grouped as starches. We know these most commonly as rice, pasta, potatoes and breads. These types of food appear to have been staples of our western diets since time immemorial (they’re not, but that’s another story). We are often told that eating these foods will leave us full, satisfied and full of a slow releasing stream of energy that is healthy and safe. Unfortunately, at least for human beings, this doesn’t always appear to be the case.
Not all grains are created equal for a start and this can be where grain advocates purposely or accidentally mislead. For instance most rice, particularly white rice, will convert to sugar almost immediately in our system and we’ve already seen some of the devastating effects of excess sugar consumption. Grains, no matter what source they come from will cause elevated insulin levels. For the very healthy amongst us, who have extremely sensitive insulin (either through good genetics, regular exercise or a combination of both) may be able to carefully use small quantities of grains to fuel their bodies through the periods of high activity. However for the vast majority of people, the excess of grains will result in almost all the same problems as sugar consumption. Many low-carb exponents are suspicious of medical advice to eat grains, many citing Government subsidies of mass agriculture. Eating grains is a very cheap and simple way of providing food, but cheap and simple is rarely the same as healthy and good...
