肥胖已成为21世纪最严峻的全球公共卫生危机之一，其蔓延速度令人震惊。据世界卫生组织最新统计，过去半个世纪全球超重人口激增 近三倍，这一数字仍在持续攀升。 传统观点将肥胖简单归结为能量失衡——即"摄入过多而消耗不足"，这种理论主导了数十年的肥胖防治策略。然而，国际知名代谢研究 专家Ba r ba r a E. Co r ke y教授的最新研究发现，肥胖的成因远比我们想象的复杂。她的突破性研究指出，现代饮食中普遍存在的食品添 加剂、环境内分泌干扰物等因素，可能正在悄然改变人体的代谢调控机制。 这些隐藏在日常生活背后的"代谢干扰因子"，正以我们尚未完全理解的方式，重塑着人类的能量代谢平衡系统。这一理论为理解全球肥 胖流行提供了全新视角，也解释了为何单纯依靠"少吃多动"往往难以取得理想效果。 随着研究的深入，科学家们逐渐意识到，对抗肥胖需要从更宏观的环境因素和更微观的分子机制双重维度着手。这场关乎人类健康的持 久战，正在揭开其复杂性的冰山一角。 ▍"少吃多动"失效之谜：科学家揭开肥胖背后的隐形推手 长期以来，"管住嘴、迈开腿"被视为对抗肥胖的金科玉律，但越来越多的人发现，即便严格控制饮食、坚持运动，体重仍难以有效下 ...

新华社北京9月29日电 美国一项最新研究显示，过量食用超加工食品会显著提升体内炎症水平，且在 老年人、吸烟者和肥胖人群中更为明显。科研人员警告说，超加工食品可能会增加癌症和其他慢性疾病 风险，并呼吁出台更严格的健康政策。 超加工食品，是指经过工业化处理的食品，如汽水、零食和加工肉类。这类食品通常富含添加剂、营养 价值大打折扣，并容易导致过量摄入。此前研究已表明，过量摄入此类食品与肥胖、癌症、心血管等疾 病，甚至过早死亡的风险增加密切相关。 由美国佛罗里达大西洋大学施密特医学院等机构组成的研究团队，基于9000余名美国成年人的国家健康 与营养调查数据，分析了其饮食习惯、体内超敏C反应蛋白水平及其他健康因素。研究显示，摄入超加 工食品最多的人体内超敏C反应蛋白水平明显更高，该蛋白是炎症的敏感标志物和心血管疾病的重要预 测指标。 研究团队依据超加工食品摄入占总能量的比例将研究对象进行分组。结果显示，研究对象每日能量摄入 的中位数有35%来自超加工食品，最低组为0%至19%，最高组为60%至79%。在调整年龄、性别、吸 烟、运动及其他健康指标后，研究人员发现，最高组人群的超敏C反应蛋白水平显著升高，炎症风险比 最低组 ...

新华社巴黎8月28日电（记者罗毓）法国国家科学研究中心参与的一项新研究表明，在热量摄入相同的 情况下，富含超加工食品的饮食不仅不利于体重管理，还会对男性生殖功能产生负面影响。研究成果已 于28日发表在美国《细胞－代谢》月刊上。 参与者先遵循其中一种饮食方案三周，然后恢复三个月的日常饮食，之后再遵循三周的另一种饮食方 案。研究人员对他们定期抽血、进行精液分析以及体重等检测。 结果显示，富含超加工食品的饮食方案使大多数参与者的促卵泡激素（刺激精子生成的激素）和睾酮 （男性生育能力关键激素）水平下降。研究还观察到精子运动能力下降的趋势。 法国国家科学研究中心代谢表观遗传学研究主任罗曼·巴雷斯说，由于女性卵细胞采集更为复杂，该研 究未涉及女性，但"观察到的效应很可能并非男性独有"。 责编：陈亚楠、王珊宁 超加工食品指经过一系列复杂的工业加工制作，添加香料、色素、增味剂、乳化剂等多种食品添加剂， 普遍含有高糖、高盐、高脂肪、低蛋白、低膳食纤维、低微量营养素的食品，如糖果、饼干、冰淇淋、 薯条和含糖饮料等。 为探究超加工食品对健康的影响，研究人员让43名年龄在20至35岁之间、身体健康的男性接受了两种热 量相同的饮食方案 ...

Core Viewpoint - The World Health Organization (WHO) has launched the "3by35" initiative, aiming to increase the actual prices of tobacco, alcohol, and sugary drinks by at least 50% by 2035 through health taxes, which will help curb chronic diseases and generate significant public revenue [1][2]. Group 1 - The "3by35" initiative is expected to raise $1 trillion by 2035, based on evidence from countries like Colombia and South Africa [1][2]. - WHO emphasizes that health taxes are one of the most effective tools to reduce harmful product consumption and generate revenue for reinvestment in healthcare, education, and social security [1]. - WHO's Director-General highlighted the need for governments to adapt to new realities and strengthen their health systems using the funds raised from these taxes [2]. Group 2 - The initiative is the first to propose a specific price increase target for tobacco, alcohol, and sugary drinks, despite WHO's long-standing support for tobacco taxes and recent calls for taxing alcohol and sugary beverages [2]. - WHO encourages governments to review and avoid tax exemptions for unhealthy industries, which could undermine national health goals [2]. - The initiative has received support from organizations such as Bloomberg Philanthropies, the World Bank, and the OECD, which will assist countries willing to take action [4].

Core Viewpoint - The article discusses the alarming rise in obesity rates in China, predicting that by 2030, the adult overweight and obesity rate could reach 70.5%, approaching levels seen in developed countries like the United States [7][18]. Group 1: Obesity Trends in China - Over the past two decades, the percentage of overweight or obese adults in China has increased from 20% in 2000 to 41% in 2023 [4]. - The National Health Commission cites research predicting that if current trends continue, the adult obesity rate in China could reach 70.5% by 2030 [7][18]. - The article highlights that while China's obesity rates are rising, they still lag behind those of developed countries, where the rates are generally higher [6][8]. Group 2: Impact of Ultra-Processed Foods - The consumption of ultra-processed foods is linked to the rising obesity rates, with a 10% increase in their caloric contribution correlating to a 7% increase in the risk of becoming overweight [11]. - From 1990 to 2019, the caloric contribution of industrially processed foods in China rose from 1.5% to 28.7%, indicating a significant increase in the consumption of ultra-processed foods [12]. - In developed countries, ultra-processed foods account for a substantial portion of daily caloric intake, with the U.S., U.K., and Canada reporting figures of 57.9%, 56.8%, and 45.1% respectively [12]. Group 3: Nutritional Recommendations - To combat obesity, the article emphasizes the importance of reducing ultra-processed food intake and increasing the consumption of natural and minimally processed foods [21][38]. - The National Health Commission has launched a "Weight Management Year" initiative, promoting dietary guidelines that prioritize balanced nutrition while considering regional dietary preferences [34][35]. - The guidelines recommend increasing the intake of dairy products and vegetables, which are high in protein, calcium, and dietary fiber, to help manage weight effectively [39].
