Glycation and sugar’s damage on skin:
“When we eat food that contains added sugar or heavily refined grains, the glucose is rapidly broken down and taken up into the bloodstream. Our body is dependent on insulin to do its job effectively- to eliminate the glucose from the bloodstream and deliver it to cells for energy or store it for later. With ongoing high consumption of added sugar, this activity can become compromised, having many detrimental effects on the body such as inflammation.
Chronic high intake of added sugar and inflammation wreaks havoc on many organs, the skin included…
- Through a process called glycation, sugar molecules form advanced glycation end products (AGEs). AGEs can attach to the collagen and elastin, resulting in wrinkles and inflammation, and can exacerbate other skin conditions like acne and rosacea.
- Glycation can cause the type of collagen produced to change, from the strong type III to the weaker type I, making skin more susceptible to damage, especially from the sun.
- Enzymes which are a product of inflammation can also break down the collagen and elastin fibres.”
Sun / UV damage on skin— Collagen Breakdown and Free Radicals
“UV radiation can cause collagen to break down at a higher rate than normal aging. It does this by penetrating the middle layer of skin (dermis), causing the abnormal buildup of elastin. When these elastins accumulate, enzymes are produced which inadvertently break down collagen and create so-called “solar scars.” Continued exposure only speeds the process, leading to further wrinkling and sagging.
