 SUGARS AND FATS: ARE WE WHAT WE EAT?
Yet the plasma membrane is not just a simple barricade; rather, the construction of this interactive sheath is a true feat of cellular engineering, orchestrated by the orderly arrangement of ball-and-stick molecules called glycolipids (lipid chains adorned with sugars) and phospholipids (lipids marked with charged cellular tags called phosphate groups).
Sugar and phosphate chemical tags target glycolipids and phospholipids for a journey throughout the cell interior, where they participate in the relay of cell signals— including those that tell a cell to grow and divide, or not.
Her experiments have shown that she can feed cells a novel synthetic sugar that is just a little bit different from a natural cell surface sugar and get the cell to build a chain of such sugars and send it to the surface for display.

 Simple FactSheet: Nutritional Management of Lipodystrophy
If blood sugars are normal and dietary fats are kept to a minimum, triglyceride levels should not be higher than normal.
Simple sugars like table sugar, regular sodas, fatty desserts, even fruit juices that quickly get broken down to simple sugar should be avoided.
Simple sugars go to the liver, and the liver makes fat out of the sugar - that's one way the triglyceride levels get increased.

 Simple Carbohydrates Guide - Simple Sugars
Carbohydrates containing only one unit of sugar (called "monosaccharides") or two sugar units of sugar (called "disaccharides") are known as simple sugars or simple carbohydrates.
Simple sugars are typically sweet-tasting (glucose derives from the Greek word for "sweet") and are rapidly metabolized by the body and converted into energy.
Simple carbs or simple sugars (except fructose) are typically high on the glycemic index, so they tend to cause a rapid rise in blood sugar.

 Carbohydrates, Sugar, and Your Child
Even though they've gotten a bad rap in the 2000s and have often been blamed for the obesity epidemic in America, carbohydrates are a necessary part of a healthy diet for both children and adults.
As the sugar level rises, the pancreas releases a hormone called insulin, which is needed to move sugar from the blood into the cells, where the sugar can be used as a source of energy.
Because many medical experts think excess consumption of refined carbohydrates (refined sugars found in foods and beverages like candy and soda, and refined grains like white rice and white flour, found in many pastas and breads) are one reason behind the dramatic rise of obesity in the United States.

 NEXUS: Sugar Blues
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.
The "quick" energy claim the sugar pushers talk about, which drives reluctant doughboys over the top and drives children up the wall, is based on the fact that refined sucrose is not digested in the mouth or the stomach but passes directly to the lower intestines and thence to the bloodstream.
Sugar of all kinds-natural sugars, such as those in honey and fruit (fructose), as well as the refined white stuff (sucrose)-tends to arrest the secretion of gastric juices and have an inhibiting effect on the stomach's natural ability to move.

 The Digestion Of Simple Sugars and Supplemental Digestive Enzymes
Only simple sugars can be absorbed into the cells of the body, and enzymes are necessary to break down the complex carbohydrates to the simple sugar stage.
The term diffusion, as it pertains to carbohydrate absorption, means the transferring of the simple sugars, which are in solution (in water), through the walls of the intestine, and then through the walls of the individual cells of the body tissues.
The sugars, meanwhile, pass through the membranes of the intestinal wall and enter the blood, where they are, for the most part, carried directly to the liver.

 Medical Encyclopedia: Carbohydrates (Print Version)
Simple carbohydrates have one (single) or two (double) sugars while complex carbohydrates have three or more.
Double sugars include lactose (found in dairy), maltose (found in certain vegetables and in beer), and sucrose (table sugar).
Also, many refined foods, such as white flour, sugar, and polished rice, lack B vitamins and other important nutrients unless they are marked "enriched." It is healthiest to obtain carbohydrates, vitamins, and other nutrients in as natural a form as possible -- for example, from fruit instead of table sugar.

Well, the reason for that is simple: we want you to enjoy your workout or race, we want you to achieve your best possible results, and we want you to do that without having stomach issues such as bloating, cramping, diarrhea, and a host of others.
Here's the deal: simple sugars (glucose, sucrose, fructose, dextrose, etc) need to be mixed in concentrations no higher than 6-8% in order to achieve an acceptable absortion osmolar value of body fluids (280-303 mOsm) and be digested with any efficiency.
However, when simple sugars and complex carbs are consumed together or near each other, it increases the solution concentration beyond what either source can be efficiently digested at.
