Sugar Confusion

There are three primary forms of sugar:

1. Glucose 
2. Galactose
3. Fructose

These three forms of sugar are not interchangeable. Each is used by the body differently. Some forms of sugar are our life force energy and others are considered by our body to be tantamount to poison. I'm going to try to quickly sum up how each form of sugar works within our body:

1. Glucose
• Glucose is the energy of life. Almost all living plants and creatures run on glucose. Glucose is made through the process of photosynthesis. It is what is found in starch and when it breaks down, it can be burned down as energy by pretty much every cell in our body. Glucose consists of two elements that mirror each other, these elements are called L-Glucose and D-Glucose. Dextrose is another name for D-Glucose. 
2. Galactose
• Galactose is only found in milk sugar. It is almost instantly turned by our liver in to Glucose. 
3. Fructose
• Fructose is rarely converted in to glucose. It is seen by our body as extraneous and is regularly converted in to liver fat. 
• Unless we are an extreme athlete (think an olympian) or if we are literally starving, our fructose remains solely as liver fat. If you are an olympian, extreme athlete, or literally starving, then your body may convert fructose in to glycogen (liver starch) which can be fished out of your liver if your body desperately needs glucose. This rarely happens. "Chronic and excess alcohol or fructose exposure both cause fatty liver disease, which drives the pathologic process of insulin resistance, and causes the same chronic diseases - obesity, heart disease, and diabetes." 

There is much confusion over the idea that Fructose is bad for us. Because many of us grew up being told that "an apple a day will keep the doctor away," we are not willing to think of fructose as potentially negative. We associate fructose specifically with fruit and we associate fruit with health. When we eat fruit, our body consumes not only fructose, but also fiber. The fiber in fruit helps limit the absorption of fructose. When you refine sugar (which pretty much means that you remove the fiber from the sugar), you absorb the sugar (fructose) all immediately. Your liver becomes overloaded with fructose and ends up converting it in to liver fat. This is why consumption of straight fructose without fiber (fruit juice, soda, honey, agave, sucrose - the combination of glucose and fructose, or generally any time that the naturally occurring fibers that were attached to the fructose are gone) causes us to gain liver fat.  

The more fructose we consume, the harder our body has to work. When we eat too much sugar (read - fructose), our immune cells secret an inflammatory messenger called a cytokines. When cytokines are excreted, our bodies become inflamed. As someone with an autoimmune arthritis who is fighting inflammation constantly, I now monitor my sugar consumption for this reason.
