The Impact of Excessive Sugar Consumption on Skin Health Analysis of Biological Mechanisms and Dermatological Effects

Introduction and purpose: Excessive sugar consumption is one of the main dietary problem of the modern Western diet. Numerous studies have shown that a high intake of simple sugars is associated with an increased risk of developing various diseases such as obesity, type 2 diabetes, metabolic syndrome, and cardiovascular diseases. Moreover, the consumption of large amounts of sugar also affects skin condition, accelerating its aging and exacerbating the course of certain dermatological conditions. This study aims to present the underlying mechanisms of these processes and demonstrate the impact of a low-glycemic index diet on skin health. Description of the state of knowledge: The skin is the largest organ of the body, and its condition is closely linked to diet. Excessive sugar consumption can contribute to biochemical changes such as skin protein glycation, increased production of reactive oxygen species (ROS), and inflammation. The glycation process leads to damage of collagen and elastin fibers, which reduces skin elasticity and contributes to the formation of wrinkles. Elevated levels of MMP-1/MMP-2 and LOX in the skin can affect collagen fragmentation and disrupt its structural integrity. Studies have also shown that a high-glycemic index diet can exacerbate inflammatory conditions such as acne and psoriasis and promote hormonal imbalances. Conclusion: In summary, excessive consumption of simple sugars significantly affects skin condition through mechanisms such as glycation, inflammation induction, and hormonal disturbances. Therefore, a low-glycemic index diet may be an effective tool in the prevention and treatment of skin diseases. Future studies should focus on gaining a more precise understanding of these relationships and developing dietary recommendations to improve skin health.
