Core Viewpoint - The incident involving a kindergarten using lead-contaminated additives in food has raised significant concerns about food safety, particularly regarding the alarming levels of lead detected in children's blood [1][4][17]. Group 1: Blood Lead Levels and Health Risks - A staggering 233 out of 251 children tested showed abnormal blood lead levels, with only 18 children having normal levels [4]. - The blood lead levels of two staff members reached 395 and 500 µg/L, far exceeding the adult reference limit of 200 µg/L in China [4][12]. - Among 74 children tested elsewhere, 70 showed elevated blood lead levels, with 22 children between 200-300 µg/L, 30 between 300-400 µg/L, 15 between 400-500 µg/L, and 3 above 500 µg/L [4][12]. Group 2: Testing Methodology and Anomalies - Discrepancies in blood lead levels were noted, with some children testing normal in the kindergarten's locality while others tested high elsewhere [6][7]. - Blood lead testing can vary based on sampling methods, and the presence of lead dust on skin can lead to false positives in fingerstick tests [8][10]. Group 3: Historical Context and Regulatory Standards - Historically, lead exposure has been significantly reduced in many countries due to regulations banning leaded gasoline and paint [25][28]. - The current reference values for blood lead levels in China are considered outdated and lenient compared to international standards, with the World Health Organization recommending a maximum of 50 µg/L [20][21]. Group 4: Sources of Lead Contamination - The investigation revealed that the kindergarten used colored additives in food, with lead levels in some products exceeding 1000 ppm, which is higher than the limits for industrial paints [37][38]. - The potential use of lead-based pigments, such as chrome yellow, in food preparation raises serious concerns about the sources of these additives [40][42]. Group 5: Global Comparisons and Case Studies - Similar incidents of lead contamination in food products have been documented globally, including cases in Hungary and Bangladesh, where spices were found to contain lead due to illegal additives [48][56]. - The case of lead contamination in spices from South Asia highlights the ongoing risks associated with food safety and the need for stringent monitoring [61][62].

#SynBio团队 | 倪俊 木质素价值化对于实现经济可行和可持续的木质纤维素生物精炼厂至关重要。近年来，木质素及其水解芳烃的生物利用 引起了广泛关注，这是实现零浪费和经济可行的生物精炼厂的关键。然而，对昂贵辅因子（例如，三磷酸腺苷 （ ATP ）、还原烟酰胺腺嘌呤二核苷酸磷酸 （ NADPH ） 和辅酶 A （ CoA ））的持续需求严重阻碍了木质素可持续地转化 为有价值的产品。为了减轻这种限制，一种可能的方法是引入辅助辅因子再生酶，这通常需要精确调节辅因子代谢网络 以防止细胞稳态的破坏。 此外，生物合成机械和辅因子再生系统之间催化活性的不平衡是有效转化的关键障碍，导致木质素有价值的分子的产量 极其有限。例如，来自木质素衍生的对香豆酸 （ pCA ） 的覆盆子酮 （ RK ） 的生产率低于 0.003 g l h ，转化率仅 为 11.3% ，姜黄素的生产率限制为 0.006 gl h 。 目前，没有通用的解决方案可以同时克服昂贵的辅因子需求和不平衡的酶活性。 因此，开发一种改善木质素生物转化途 径的通用策略是 可取的。 【SynBioCon】 获 悉， 上海交通大学倪俊 团队于 2025 年 5 月在期刊 ...

本次行动的核心任务，是在三年内帮助各类人群树立科学的体重管理观念，切实降低肥胖及相关慢性疾病的发病率。 ▍国人超重肥胖现象 《中国居民营养与慢性病状况报告》数据显示： 以下文章来源于体重管理三年行动 ，作者体重管理三年行动 体重管理三年行动 . 响应国家"健康中国2030"战略，落实"体重管理年"三年行动，本账号发布权威资讯 2025年3月9日，国家卫生健康委员会正式拉开了为期三年的"体重管理年"专项行动，旨在以科学减重和健康生活方式，积极应对我国不断加剧 的超重与肥胖难题。 我国6-17岁青少年儿童中，超重和肥胖比例已高达19%；成年人群的超重肥胖率更是达到50.7%。 过去15年，青少年肥胖率激增了12倍，职场人士"过劳肥"以及老年人肥胖问题也日益严重。肥胖不仅影响外观，还与高血压、糖尿病、心脑血 管疾病等多种慢性病紧密相关。这些慢性病的医疗负担占全国疾病总负担的70%以上，直接医疗支出每年超过2400亿元。 如何判断肥胖？ 主要依据BMI和腰围等指标。 BMI（体质指数）=体重（kg）÷身高（m）²，正常范围为18.5～23.9。 例如，身高1.66米、体重56公斤，则BMI=56÷（1.66×1.66 ...

01 微醺启示录 文 | 酒讯 方圆 白酒往低度市场扎堆，啤酒掀起无醇浪潮，连隔壁药房都爆发了一波解酒经济。理性饮酒，力图从源头和终局把酒精弱 化甚至"消灭"。 从根源上来看，一切变化的源头来自主力消费人群的迭代。年轻人如今以微醺姿态坐在酒桌"C位"，放下豪放的狂饮酒 杯，时代交接悄然完成：曾经被质疑 "不懂酒" 的人，正以理性重新定义酒杯里的时代；从低度白酒到无醇啤酒再到解 酒药，他们滋养出一片新的酒业天地。 "理性饮酒"的概念自始至终一直存在人类饮酒历史中。西周初年周公旦颁布的《酒诰》，警示人们切不可因沉湎于酒而 误国、误事、误身；《战国策》中也记录有大禹"后世必有因酒而亡国者"的观点；公元前518年，孔子在河南鹿邑留下 了"唯酒无量，不及乱"的处世箴言。 进入现代社会，英国在1981年首次提出"Sensible Drinking"（明智饮酒）概念，2004年帝亚吉欧等国际烈酒巨头将"理性 饮酒"概念引入中国，2008年中国酒业协会正式提出"理性饮酒"理念，以及2015年中国首个"全国理性饮酒日"启幕。从 文化根基到行业实践，理性饮酒与中国酒水消费市场相生相伴的紧密关系已经跨越几千年时光。 业协会公众号截 ...

"今天，你吃红菜头了吗？" 如果这个问题在五年前被提起，大概会被当成冷笑话——毕竟这玩意儿长得像沾了泥的萝卜，味道还带点泥土的倔强，还有一个土名： 甜菜根。 然而一夜之间，红菜头成了都市中产的"社交硬通货"， 奶茶是不可以喝的，但红菜头制成的果茶喝了是能彰显privilege的； 都市隶人的吊命水是没什么稀奇的，但加了红菜头的吊命水是能实现阶级跃迁的。 甚至某红书已变为红菜头种植基地，成为三明治、能量碗的新成员——谁的健康餐里头要是没红菜头，那就显得你很不自律。 问就是，"不是吧（捂嘴笑），不会还有人没在吃红菜头吧？" 中产心中，甜菜根不叫甜菜根，而是"生命之根"、"欧洲灵芝"。 "总感觉吃了它，就能像魂斗罗破解版一样获得无限条命。" 不过，第一批吃到红菜头的普通人都懵了： "这么难吃的根茎蔬菜，喜欢的人是有异食癖吗？" 红菜头，中产新宠 有位诗人曾说过，江山代有网红出，各割中产两三年。 红菜头也不例外。 2018年之前，红菜头在国内的定位堪比当年的一博： 小范围待爆，本质上不红。 它潜伏在健身博主的餐盘角落，搭配鸡胸肉和西兰花，成为"自律人设"的标配道具。 那时的红菜头，是欧美健康食谱的"舶来品"，名字还带 ...

通过进一步的化学成分分析和复杂的统计建模，团队最终锁定了5种可能调节辣味的化合物，其中3 种，即辣椒苷Ⅰ、玫瑰苷和姜黄糖脂A，被证实能够有效降低辣度。 这一发现不仅为食品工业定制个性化辣味提供了新思路，还可能推动家用"减辣调料"的开发。此 外，这些天然辣味抑制化合物在医学领域也具有潜在应用价值，例如为研发镇痛药物提供新的分子靶 点。（记者张佳欣） 史高维尔辣度指标是依据辣椒中辣椒素和二氢辣椒素的总含量来评定辣度等级。像甜椒，其辣度等 级为0史高维尔辣度单位（SHU）；而最辣的辣椒，辣度等级能达到数百万SHU。然而，研究团队发 现，辣椒中可能存在其他能够调节辣味的成分。 团队收集了10种辣椒的干粉样本，包括阿勒波辣椒、塞拉诺辣椒、鸟眼辣椒、费塔利辣椒和哈瓦那 辣椒。通过液相色谱—质谱联用技术，他们精确测定了每种辣椒中辣椒素和二氢辣椒素的含量。随后， 经过训练的品尝小组对番茄汁中辣椒粉的辣度进行了评估。结果显示，尽管样本中辣椒素和二氢辣椒素 的含量相同，但不同辣椒的实际感知辣度却存在显著差异，这进一步证实了其他化学成分对辣味的影 响。 原标题：有些辣椒自带"降辣神器" 人们感受到的辣味是由辣椒素类化合物带来的。然 ...
