The skin troubles we face in modern times are not solely due to stress or environmental pollution. When the wisdom of Donguibogam meets modern science, we can uncover the surprising impact of sugars in fruit on the skin. At the very core lie the blood sugar spike and glycation.
When we eat a large amount of sweet fruit, we experience a blood sugar spike where blood glucose surges rapidly and then plunges. When blood glucose rises suddenly, the pancreas excessively secretes insulin to bring it down. The problem is that this excessive insulin secretion affects multiple hormones, negatively impacting the skin. It stimulates the secretion of insulin-like growth factor (IGF-1), which triggers the sebaceous gland to increase sebum secretion, clogging pores and serving as a major culprit in accelerating acne development. Moreover, it activates inflammatory responses, aggravating existing inflammatory acne or inducing new inflammatory troubles. It is much like pouring fuel on a burning fire.
Going beyond this, blood sugar spikes accelerate glycation, the prime driver of skin aging. Glycation refers to the process where protein in our body, especially collagen and elastin, crucial for skin elasticity, bonds with excess sugars in the bloodstream to produce advanced glycation end products (AGEs). These AGEs stiffen collagen and elastin fibers and cause cross-linking, reducing skin elasticity and deepening wrinkles. Furthermore, they directly damage skin cells, inducing hyperpigmentation, making the skin tone dull, and even deteriorating skin regeneration capacity. Just as a sponge stiffens and hardens, it causes the skin to lose flexibility and vitality.
In addition, the connection between gut health and skin cannot be overlooked. Excessive sugar intake promotes the proliferation of harmful bacteria in the intestine and damages the intestinal mucosa, potentially causing leaky gut syndrome. When the intestinal barrier becomes loose, undigested food debris and toxins leak into the bloodstream, triggering a systemic inflammatory response, which easily leads to skin breakouts. In fact, research continuously shows that gut dysbiosis is deeply linked to various skin disorders, including acne, atopy, and psoriasis.
Ultimately, while the temptation of sweet fruit offers momentary pleasure, you must remember that inside our body, it can bring inflammation and aging to the skin through the complex interplay of blood sugar spikes, glycation, and compromised gut health. Even when eating fruit for your health, making smart choices and consuming it in moderation is essential to maintain clear and healthy skin. Do not miss the small signals your skin sends you.
