Too much sugar in the body makes collagen cells less mobile and thus causes stiffness of tissues, including skin. (11) Loss of elasticity in the skin becomes apparent with the advent of wrinkles, among other things.
Plus, increased levels of sugar cause acne and dermatitis. Carbohydrates like bread, cereal, rice, and pasta cause an increase in insulin and androgen (a male sex hormone) production. Androgens cause the glands in the skin to produce extra oil, clogging pores and resulting in pimples. (12)
Also, candida is a yeast that lives in the digestive tract and on the skin. As a yeast, it thrives on sugar. Eating excess sugar makes yeast proliferate, resulting in nail infections, vaginal infections, athlete’s foot, and oral thrush. (13)
What’s more, high blood sugar can also lead to diabetic neuropathy, causing tinggling and pain in the feet.
Over time, internal inflammation and increased insulin production can cause cells to abnormally and rapidly reproduce. Cancer cells live on sugar, so that’s one more reason to ditch the sugar habit.
