Sugar is bad for our waistline and is finally being noticed for its impact on other health conditions like diabetes and heart health. In the past, dermatologists did not believe that diet can trigger acne and other skin conditions, but now there is mounting evidence. The foods you eat play a big role in the health of your skin and sugar is one of the worst culprits.
1. Insulin
When we eat sugar and other refined carbohydrates, the body processes it into glucose. The presence of glucose in the blood then triggers a release of insulin. The more sugar and refined carbs you eat, the higher the insulin levels. High insulin levels cause inflammation throughout the body. Specifically, it leads to a breakdown of collagen and elastin resulting in sagging skin and wrinkles.
2. Glycation
Sugar molecules bond to protein and fat molecules in our body causing them to become stiff and less functional. Collagen and elastin are the fibers keeping skin firm and elastic and are among the most vulnerable proteins in this process.
3. Testosterone
When women eat more sugar, it starts a cascade beginning with the increase insulin, which then signals the ovaries to increase production of testosterone. Testosterone then over-stimulates oil glands on the skin and make hair follicles more ‘sticky’, thus more likely to clog pores.
4. Immune system
Sugar weakens the immune system and can directly impact skin health. This may mean you are more susceptible to bacterial infections, including acne or recovery from wounds may slow down.
My tips for healthy, glowing skin:
Dietary changes:
-
decrease the amount of sugar, refined carbohydrates and dairy to minimize spikes in insulin and inflammation
-
low sugar, refined carbohydrates and dairy; high in fruits and vegetables for antioxidants to fight inflammation
-
drink water (with electrolytes) to help move nutrients where they need to go and to remove toxins and waste
Healthy fats
-
increase foods rich in omega-3 fats, like oily fish, nuts, seeds, olive oil and avocado for good cell structure and to fight inflammation
Lifestyle changes
-
get more sleep to give the body time to repair and clean out toxins and waste
-
manage stress to minimize insulin spikes
