新研究显示超加工食品比外界想象的更不健康_我的网站

A |     长期以来，人们都知道，以超加工食品（UPF）为主的饮食更有可能导致肥胖。但最近的研究表明，高UPF消费也会增加心血管疾病、痴呆症的风险，而且根据最近一项涉及50,000名卫生专业人员的美国研究，还会增加患结肠癌的风险。    (ECNS) -- The rapid growth of artificial intelligence is driving a new wave of electricity demand, putting nuclear power back in the spotlight.    China, which has the world's largest nuclear power capacity under construction, is accelerating the development of nuclear energy to provide reliable, low-carbon electricity for its growing economy and emerging AI industries.    According to the National Energy Administration, China has 112 nuclear units in operation or approved, with a combined capacity of 125 million kilowatts — the highest globally. Its nuclear capacity under construction also ranks first worldwide.        As China continues to expand its nuclear power fleet, which province leads the country in nuclear energy? And why is China stepping up investment in the sector?    Guangdong Province has emerged as China's nuclear leader. In the first half of 2026, its nuclear generation reached 57.31 billion kilowatt‑hours, supported by a complete industry chain spanning design, equipment manufacturing, construction and operation.    Guangdong has also developed a complete nuclear power industrial chain spanning design, equipment manufacturing, construction and operation.    The State Council recently approved the third phase of the Taipingling Nuclear Power Plant in Guangdong, marking another major step in the province's nuclear expansion following the approval of five nuclear power projects, including the Taishan project, last year.    With major nuclear power bases including Daya Bay, Ling'ao, Yangjiang, Taishan and Taipingling located along its coastline, Guangdong is expected to see nuclear power generation rise significantly as new units come online, helping meet growing electricity demand from industries such as AI and data centers.    Fujian Province, meanwhile, has the highest share of nuclear power in its electricity generation mix. Nuclear energy accounted for 28.1% of the province's total power generation, according to the NEA, meaning nearly three in every 10 kilowatt-hours generated in Fujian came from nuclear power.    With major nuclear power bases in Ningde, Fuqing and Zhangzhou, nuclear energy has become a key pillar of Fujian's power supply.    The expansion of nuclear power is being driven in part by rapidly growing electricity demand in the age of artificial intelligence.    In the United States, major technology companies are also turning to nuclear energy to secure reliable, low-carbon electricity. Microsoft has signed a 20-year agreement linked to the restart of the Three Mile Island nuclear plant, while Google has announced plans to procure power from small modular reactors.    As AI development drives electricity demand higher, the convergence of artificial intelligence and nuclear power is beginning to reshape the global energy landscape.    China is also part of this growing "AI + nuclear power" trend. As the clean energy transition gathers pace, the country's expanding nuclear power hubs are providing a stable source of electricity to support both its digital economy and broader green transformation.    (By Gong Weiwei)                            。《自然评论-临床肿瘤学》的一项研究发现，1990年以后出生的人比1970年以前出生的人更有可能在50岁之前患癌症。

B | 人们怀疑UPF可能是导致这种发展的一个因素。据估计，英国50%以上的卡路里摄入量来自UPF，这不是一个短暂的健康恐慌，而是一个涉及到我们烹饪生活方式核心的问题。NOVA是一个广泛使用的食品分类系统，它根据食物的加工程度将其分为四类。

C | 除了新鲜水果和生蔬菜之外，几乎所有的食物都要经过某种程度的加工。烹饪是一个过程，它通常涉及添加的成分，如油和盐。
在NOVA的第一类中，第1组是未加工或加工程度最低的食品（水果、蔬菜、肉、蛋、牛奶）。第2组是由加工过的烹饪原料组成，如糖、油和黄油。

D | 第3组是加工食品（罐装蔬菜和鱼，面包，果酱）。

E | 第4组是超高加工食品，这些食品大多蛋白质和纤维含量低，而盐、糖和脂肪含量高，并经过了工业干预，如挤压、模压和研磨。现代食物的超加工性质通常意味着植物和动物细胞的复杂结构被破坏，变成一种营养空洞的泥浆，我们的身体可以异常迅速地处理。有非常明确的观察数据显示，超加工食品摄入量较高的人健康状况较差，无论是癌症、心血管疾病、高血压、肥胖还是2型糖尿病。虽然UPF的问题在科学上已被证实，但就个人而言，它并不容易处理。毕竟，UPF是如此普遍，以至于将它们从我们的饮食中完全剥离将是一个后勤和耗时的噩梦。更重要的是，人们喜欢它们的便利性，并经常津津乐道于其工业化的味道。不久前，对UPF的主要批评是它缺乏营养物质，为了应对这种缺失，添加了所谓的健康营养物质。

F | 现在，食品科学正在更仔细地研究天然食品结构和超加工食品被人体分解的不同方式。
