Sugar…..Not So Sweet For Your Gut And Skin

Sugar…..Not So Sweet For Your Gut And Skin

The Western Diet does not support the demands  that come with modern living. In fact, it amplifies naturally occurring metabolic events of inflammation and oxidation  throughout our whole body1 with damaging consequences. The increased intake of processed foods encourages  the development of hyperinsulinemia and insulin resistance, loss in microbiome diversity, and an abnormal activation of the sympathetic nervous system 2,3 which all cause a slow erosion of our mental and physical health. Depending on your genetic susceptibility, these changes ultimately lead to cardiovascular disease, depression, anxiety, obesity, diabetes, respiratory problems, and  cancer. 

From a young age,  these health risks are  more evident in people living removed from the natural environment. By contrast, they are virtually absent in hunter-gatherers and other non-westernized populations4. Therefore, with the environmental toll of modern living, we need to be proactive with diet and additional supplementation to improve our resilience. 

One of the biggest barriers to our health is the overconsumption of fructose, a widely used sweetener in processed foods. Fructose is a simple sugar naturally occurring in fruits and vegetables and is largely harmless unless you  suffer from fructose malabsorption or genetic predisposed fructose intolerance. 

However, fructose by itself is widely used as a sweetener and is one of the most dangerous ingredients of the Western Diet. One form is high fructose corn syrup, which has been associated with liver damage, obesity, diabetes and cancer. Studies on Fructose indicate that it damages the gut5 ,weakening the  gut barrier 6, the surface that determines how we process incoming information from the outside world. This effect of sugar intake on the skin barrier has equally damaging consequences increasing its fragility and sensitivity to the environment.

Fructose is associated with symptoms of irritable syndrome 7 and SIBO (Small Intestine Bacterial Overgrowth). According to research published in Nature 8, fructose increases gut permeability leading to intestinal ‘leakiness’ of toxins. into the bloodstream. In the cardiovascular system fructose increases blood pressure, blood vessel stiffness and hyperlipidemia9 and for in our bones and cartilage, fructose makes our bones fragile  disrupting collagen structure.10  

For the skin, imbalance in sugar metabolism contributes to acne 11 and accelerates the aging process. Here the weakening of collagen causes visible changes including  dry skin, fine lines and wrinkle formation as  the skin loses its  elasticity and ability to retain hydration. 13

The low fiber intake in the Western Diet 14 further influences the effect of sugar on our health with  low fruits and vegetables  in our diet. Fiber  helps to improve gut function and  control blood sugar levels.  Soluble fiber promotes healthy microbial balance in the gut 15, slows the absorption of sugar and reduces  glycation 16. Glycation is a process where the excessive exposure of proteins and lipids to sugar produces Advanced Glycation End Products. AGE’s are damaging to every cell in the body and have been linked to cataracts, Alzheimer’s disease, cardiovascular disease, stroke, asthma, neuropathy, and arthritis including accelerated skin aging.. The benefits of soluble fiber are further enhanced with the presence of polyphenols 17 which encourages the growth of healthful bacteria  in the gut and the production of powerful anti-inflammatory and antioxidant  metabolites that counter the effects of AGE’s.

At KAIBAE we emphasize the use of wild plants such those present in Gut /Skin Resilience with Baobab, rich in prebiotic fiber, vitamin C and polyphenols 18 to amplify probiotic balance and fortify gut and skin barrier health.  We recommend a whole food19  Mediterranean diet. A diet that is largely composed of plants, wild caught fish and organic fruits and vegetables, while avoiding gluten and high fructose  processed foods. These dietary recommendations can further be personalized  with your health care provider addressing food sensitivities and allergies.
