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].

几十年来，百慕大三角一直是神秘的代名词。失踪的船只、坠毁的飞机、无线电突然中断……各种 传说让这片位于美国佛罗里达、波多黎各和百慕大之间的海域蒙上了一层超自然色彩。但如果把目光从 海面移向地下，科学家发现，最大的谜团或许不是航行日志里记载的各种遭遇，而是深藏在地壳之下的 百慕大"身世之谜"。 从地质构造上看，百慕大非常特殊。它坐落在一片被称为"海洋隆起带"的区域，这类隆起通常出现 在火山热点之上。最典型的例子是夏威夷，炽热的地幔物质从深处上涌，穿透地壳，形成火山岛，同时 把周围的海底整体抬高。但随着板块移动、火山活动停止，这种隆起会逐渐冷却、下沉。 从深埋地壳的岩石层，到突如其来的巨浪，百慕大三角的神秘，或许并不需要超自然力量来解释。 真正令人惊叹的，是地球本身依然隐藏着许多尚未被完全理解的极端过程。它们静静地躲在未知的幕 后，直到被科学一点点发现。 进一步分析显示，在百慕大地壳之下，还存在着一层额外的岩石。美国卡内基科学研究所地震学家 威廉·弗雷泽指出，通常情况下，海洋地壳下方会直接过渡到地幔，但在百慕大，"中间多出了一层"。 这层岩石并非普通沉积物，而是冻结的岩浆。它形成于百慕大最后一次火山活动期间，当时 ...
