Hi, I'm Stella Metsovas and today, we're going to talk about the best sources of glucose versus fructose. Okay, what is glucose and what is fructose? Both glucose and fructose are carbohydrates, commonly referred to as simple sugars. Sugar is found naturally in whole foods and is often added to processed foods to sweeten them and increase the flavor. They both provide the same calories per gram, but they are processed in a totally different way within our bodies. Simple carbohydrates are classified as either monosaccharide or disaccharides. Monosaccharides are the simplest form basic units of carbohydrates and are made up of only one sugar unit. Glucose and fructose are monosaccharides and are the building blocks of sucrose and disaccharides. The most important monosaccharide is glucose, the body's preferred energy source. And glucose is also called blood sugar as it is circulating in the blood by initiating our metabolism. Your body processes most carbohydrates you eat into glucose, either to be used immediately for energy or to be stored in the muscle cells or the liver as glycogen for later use. Fructose is a sugar found naturally in many fruits and vegetables and added to many processed foods. Fructose is different from other sugars because it has different metabolic pathways and is not the preferred energy source for muscles or even the brain. Fructose is only, and I repeat, only metabolized in the liver. A trick I use to see if people are eating a typical Westernized diet is to check blood triglycerides. If they're elevated, oftentimes this is due to chronic intake of fructose, mostly from processed foods. My top food choices for glucose include root vegetables like turnips, sweet potatoes, yams, celery, beets, carrots and parsnips. Not only do they provide you with a healthy dose of clean burning carbohydrates and sugars from glucose, they're packed with minerals as well.
