Core Viewpoint - The discussion around "poor-quality carbohydrates as a driver of chronic inflammation" has gained significant attention, highlighting the contrasting health impacts of different types of carbohydrates. Long-term consumption of poor-quality carbohydrates can disrupt metabolism, induce chronic inflammation, and increase disease risk [1]. Group 1: Mechanisms of Poor-Quality Carbohydrates - Poor-quality carbohydrates are defined as highly processed foods low in dietary fiber, high in glycemic index, and significantly depleted of nutrients, including sugary drinks and refined grains [1]. - These foods disrupt blood sugar metabolism, leading to inflammation through a cycle of high sugar intake, insulin resistance, and increased inflammatory markers [1]. - They also damage gut microbiome balance, leading to "leaky gut" syndrome, where toxins from harmful bacteria enter the bloodstream, triggering systemic inflammation [2]. - Excess sugar can form advanced glycation end products (AGEs), which promote inflammation and accelerate cellular aging, resulting in visible skin aging [2]. Group 2: Health Risks Associated with Poor-Quality Carbohydrates - Chronic inflammation is just one consequence; poor-quality carbohydrates act as catalysts for various chronic diseases. They provide weak satiety, leading to overeating and increased visceral fat, which releases inflammatory factors [3]. - The World Health Organization has identified excessive intake of poor-quality carbohydrates as a risk factor for type 2 diabetes and cardiovascular diseases, with insulin resistance being a key contributor to these conditions [3]. - Chronic inflammation can create a favorable environment for cancer cell growth, with studies indicating a higher risk of colorectal and breast cancers among those consuming high-glycemic foods [3]. Group 3: Recommendations for Healthy Carbohydrate Consumption - The focus should be on replacing poor-quality carbohydrates with high-quality options characterized by slow glycemic response, high fiber content, and minimal processing. Suggestions include mixing white rice with whole grains or substituting starchy foods with sweet potatoes and corn [4]. - Total carbohydrate intake should align with dietary guidelines, comprising 50%-65% of total energy, with whole grains and legumes making up 50-150 grams daily, and ensuring a fiber-to-carbohydrate ratio not exceeding 10:1 [4]. - Combining carbohydrates with proteins and healthy fats can slow digestion and enhance satiety, promoting better health outcomes [4].

Core Viewpoint - The article emphasizes the hidden dangers of visceral fat, which can lead to significant health risks even in individuals with normal body weight. It highlights the importance of awareness regarding visceral fat and its impact on metabolic health and disease risk. Group 1: Visceral Fat as a Health Threat - Visceral fat is the fat that surrounds internal organs such as the liver, pancreas, and intestines, and it is not visible like subcutaneous fat. This type of fat can lead to metabolic disorders and inflammation, posing serious health risks [6][7]. - The World Health Organization (WHO) suggests that a waist circumference of ≥90 cm for men and ≥85 cm for women significantly increases the risk of visceral fat accumulation [7]. - Research published in The Lancet indicates that a 10% increase in visceral fat raises the risk of cardiovascular diseases by 13% and doubles the risk of diabetes [7]. Group 2: Causes of Excess Visceral Fat - High-sugar and high-fat diets are primary contributors to excess visceral fat. Consuming refined carbohydrates and trans fats leads to increased triglyceride synthesis in the liver, resulting in fat accumulation around internal organs. A study from Harvard University found that drinking one sugary beverage daily can increase visceral fat by 15% annually [9]. - Sedentary behavior and lack of exercise significantly contribute to visceral fat accumulation. Data from the Journal of Sports Medicine shows that sitting for two consecutive hours can reduce the activity of fat-decomposing enzymes by 90% [10]. - Chronic stress and lack of sleep also play a role in visceral fat accumulation. High levels of cortisol, the stress hormone, promote fat storage in the abdominal area. Individuals who sleep less than five hours per night accumulate visceral fat 30% faster than those who get adequate sleep [11].
