Document Summary
Glucose, fructose, and galactose are the most common monosaccharides in our diet. Monosaccharide means of one single sugar molecule aka glucose. Monosaccharides contain six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. Glucose is the most abundant sugar in our diets and in our bodies. Fructose is sugar naturally found in fruits and vegetables. In many processed foods, fructose is artificially created in something that is known as high-fructose corn syrup. Galactose does not occur alone in foods, it joins together with glucose to create lactose, making lactose a disaccharide. Ribose is not really found in our diets but our bodies produce it naturally anyway. Complex carbohydrates are long chains of glucose molecules called polysaccharides. There are two types of starch: amylase and amylopectin. Our bodies digest starches down to glucose and we use this glucose to fuel our bodies. However, some starches are not digestible and they are called resistant starches.
