"There is a natural process in your body called glycation. It happens when the glucose in your bloodstream attaches to proteins to form harmful molecules called advanced glycation end products or AGEs for short. It’s a pretty simple process. The more sugar you eat the greater the number of AGEs you develop.
According to Dr. Fredric Brandt, dermatologist and author of 10 Minutes 10 Years: “As AGEs accumulate, they damage adjacent proteins in a domino-like fashion.”
Most vulnerable to this type of damage are the collagen and elastin protein fibers that keep your skin firm and elastic. Collagen is the most prevalent protein in your body. Once damaged, the normally springy and resilient collagen and elastin fibers become dry and brittle. This leads to wrinkles and sagging skin. According to a study published in the British Journal of Dermatology, this aging effect starts to show itself in the mid 30s and then increases rapidly after that.
In addition to damaging your collagen, the sugar side effects affect the type of collagen your body produces. The most abundant types of collagen in your skin are types I, II, and III. Collagen type III is the most stable and long lasting. The process of glycation will transform collagen type III into type I which has less volume and is more easily damaged. According to Dr. Brandt, “When that happens the skin looks and feels less supple!”
High-fructose corn syrup has the most of all sugar side effects. High-fructose corn syrup is used heavily in processed foods because it is sweeter, extends the shelf life, and is cheaper to produce. You will find it in most sodas, fruit-flavored drinks and packaged foods. Unfortunately, it produces the greatest number of AGEs.
To compound the problem, AGEs also deactivate your body’s natural antioxidant enzymes to reduce your antioxidant levels. This leaves you even more vulnerable to sun damage from free radicals which are the leading cause of aging for your skin."
