本周是"中国减盐周"。盐是维持人体正常生命活动的重要物质，但是，长期高盐饮食危害大，很多疾病都跟食盐摄入量过多有关。 据了解，目前我国居民食盐摄入量处于较高水平，成年人每天食盐平均摄入量为11克，超过世界卫生组织和《中国居民膳食指南》推荐上限的2倍。从2019 年开始，我国将每年9月15日所在的一周设立为"中国减盐周"。9月15日这个日子，其实就是"就要5克"的谐音。 减盐的三大谣言 你中招了吗？ 关于吃盐，网络上流行着很多说法。有人怕少盐会抽筋，有人觉得血压正常就不用管，还有人把"玫瑰盐""海盐"当成健康护身符。事实上，这些看似合理的 说法，其实是谣言。 谣言三：玫瑰盐 海盐更健康 吃多点也无妨 首都医科大学附属北京友谊医院营养科副主任医师 葛智文：抽筋更多是与过度疲劳或脱水有关系，过量补盐反而会增加身体负担。 谣言二：没有高血压 不必刻意减盐 这是最普遍的误解之一。很多年轻人觉得自己血压正常，就认为与减盐无关。而事实上，高盐饮食的危害往往是"隐形的"。今天的"口重"，可能就是十年后 的"高血压"。 首都医科大学附属北京友谊医院营养科副主任医师 葛智文：高盐饮食的危害是长期多方面的，几乎对所有年龄段的人都会 ...

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - **Macro Environment**: Domestic policy signals are released, leading to a positive sentiment. The US has reached trade agreements with Japan and the EU, improving market sentiment [4]. - **Supply - Demand Situation**: In the East China region, supply - demand fluctuations are relatively limited this week, with no planned device maintenance and sufficient supply. The off - season continues as non - aluminum demand shows no significant improvement. The inventory of liquid caustic soda in the main production areas of Shandong Province remains at a low level [4]. - **Overall Logic**: Caustic soda has strong cost support at the bottom. The domestic "anti - involution" drives the market sentiment to strengthen. However, if the futures price has a high premium over the spot price, beware of the risk of a decline [4]. - **Strategy Suggestion**: For the caustic soda 2509 contract, the upper reference pressure level is 2750 yuan/ton, and the lower support level is 2350 yuan/ton [4]. 3. Summary According to the Table of Contents 3.1 Market Review - **Spot Market**: The price of Shandong liquid caustic soda remained stable. The basis of Shandong 32% liquid caustic soda widened.

The storage capacity ratio was 24.06%, a month - on - month increase of 1.82%. Except for the Northwest and Central China, the storage capacity ratios in other regions increased [30]. - **Regional Inventory**: In North China, inventory increased due to high - price downstream resistance and increased supply. In South China, inventory rebounded as the main factory resumed full - load operation. In Central China, inventory decreased as some enterprises' sales improved. In East China, inventory increased due to the off - season of non - aluminum demand and general export orders. In the Northwest, inventory decreased as downstream procurement enthusiasm increased. In Southwest China, inventory increased slightly as enterprises maintained production and downstream demand was mainly for rigid needs [30]. 3.2.4 Liquid Chlorine - **Price**: As of July 24, 2025, the price of liquid chlorine in Shandong decreased, with a weekly average price of - 400 yuan/ton, a month - on - month decrease of 1.75%.
