"从宏观上来讲，体重得到控住，本质上还是总摄入量减少导致的。"成都市第七人民医院中医科&中西 医结合科副主任医师林艳解释，体重控制的关键点在于整体的热量摄入是否超标，因此猪油能不能助 力，在于其和其他食物，特别是和碳水组成的食物热量比有多大，总热量有多高。"猪油本质上就是脂 肪，与碳水、糖等相比，其能提供更强的饱腹感，一定程度上能帮助减少总热量摄入。" 而就抑制慢性炎症方面，林艳表示，猪油含有单不饱和脂肪酸，加上其中还含的维生素D1、维生素E等 天然的抗氧化剂，本生也会有一定抗炎症作用。"另外和一些植物油相比，猪油所含的Omega-6相对低 一些，这也有助于平衡脂肪酸的摄入比例，从而一定程度上达到抗炎效果。" 建议搭配蔬菜 转自：成都日报锦观 每天吃点猪油有助于控制体重? 专家建议这样吃更健康 昨日，#每天吃猪油可控制体重和慢性炎症#的话题冲上热搜，在网络上引发热议，研究专家建议，成年 人每天烹饪用油量以25克至30克为宜，其中猪油的摄入量占一半左右。评论区内不少网友感到困惑，印 象中会导致肥胖的猪油怎么突然变成了控制体重的"良药"，随之而来的便是猪油到底能不能吃的争论。 猪油到底是让人发胖还是能助力体重控制 ...

脂肪沉积引起的肥胖和脂肪炎症是2型糖尿病的重要发病基础。对比猪油、茶油和花生油，研究团队在小鼠身上模拟了人类少吃油的健康饮食模式（脂肪 供能25%）。一个意外结果是，适量吃猪油的小鼠，比吃植物油的小鼠更"瘦"且炎症更轻。具体来说，与吃茶油的小鼠相比，吃猪油的小鼠总体脂肪少了 近1/3（29%）；吃猪油的小鼠体内，加剧炎症的分子（如IL-6）更少，而缓解炎症的分子（如IL-10）和相关抗炎免疫细胞更多。这说明在控制总量的前 提下，猪油可能比某些植物油更有助于控制体重和慢性炎症。 团队进一步揭示了猪油发挥益处的分子机制。通过非靶向代谢组学分析，团队发现摄入猪油可显著提升血清中牛磺胆酸的水平，而这一关键分子正是连接 饮食与代谢的核心"信使"。具体来说，猪油会在人体内"任命"一个叫牛磺胆酸的"特殊信使"，信使在血液里的数量也会增加。该"信使"一方面给脂肪细胞 下令，加速分解脂肪变成能量；另一方面会在免疫细胞里发出安抚信号，让那些容易引发炎症的暴躁免疫细胞转变成温和维稳型，从而减轻脂肪组织内部 的炎症。 湖南农业大学猪与人类健康科研团队发现，适量摄入猪油可减少脂肪沉积和脂肪炎症。研究人员建议，成年人每天烹饪用油量以25 ...

Core Viewpoint - The source of dietary fat significantly influences anti-tumor immunity in obese individuals, with animal fats impairing immune response and promoting tumor growth, while plant fats do not have this negative effect [5][7][9]. Group 1: Research Findings - A study published in Nature Metabolism indicates that high-fat diets based on animal fats (lard, beef tallow, or butter) weaken anti-tumor immunity in obese mice and accelerate tumor growth [5][7]. - In contrast, high-fat diets based on plant oils (coconut oil, palm oil, or olive oil) do not exhibit this detrimental effect, with palm oil even enhancing anti-tumor immunity and slowing tumor growth in obese mice [5][7][9]. - The research highlights that the metabolic byproducts of animal fats, particularly long-chain acylcarnitines, strongly inhibit NK and CTL cells, leading to impaired immune function [9]. Group 2: Implications for Cancer Treatment - The findings suggest that dietary modifications, such as replacing animal fats with plant oils, could be beneficial for obese cancer patients undergoing treatment, potentially lowering their cancer risk [5][6][9]. - The study emphasizes the importance of dietary fat composition in maintaining a healthy immune system and improving treatment outcomes for obese individuals with cancer [9].

Core Viewpoint - Recent research indicates that lard has unique nutritional benefits in combating obesity and improving gut health, outperforming certain vegetable oils [1] Group 1: Research Findings - A study conducted by experts from the Chinese Academy of Agricultural Sciences shows that mice fed with lard had lower body weight and less fat deposition compared to those fed with corn oil and canola oil [1] - Mice consuming lard also exhibited significantly lower serum cholesterol levels than those consuming corn oil and canola oil [1] Group 2: Publication Details - The research findings were published in the international journal "Food Science and Human Health" [1]

Core Viewpoint - The negative impacts of the U.S. tariff policy have exceeded market expectations, causing troubles for the U.S. economy and increasing uncertainty in the global economy, reminiscent of the disastrous effects of the Smoot-Hawley Tariff Act in the 1930s [1][7]. Historical Context - The Smoot-Hawley Tariff Act, initiated in 1929, aimed to protect U.S. agricultural interests by significantly raising tariffs on over 20,000 imported goods, with rates reaching as high as 60% [2][3]. - The act faced strong opposition from academia and business but was signed into law by President Hoover, leading to retaliatory tariffs from other countries and igniting a global trade war [2][3]. Economic Consequences - Following the implementation of the Smoot-Hawley Tariff, U.S. imports from Europe plummeted from $1.334 billion in 1929 to $390 million in 1932, while exports dropped from $2.341 billion to $784 million, resulting in a 67% decrease in trade volume [3]. - The U.S. unemployment rate soared to 25.1% by 1933, and the Dow Jones Industrial Average fell by 89% from its peak in 1929 [3][4]. - The global trade volume and industrial output also suffered, with a 66% decline in global trade and a 33% drop in industrial output by 1934 [3][4]. Modern Implications - The current U.S. tariff policies, initiated under the Trump administration and continued by the Biden administration, have not achieved their intended goals of manufacturing return or trade deficit reduction, instead causing economic damage and loss of credibility [7][8]. - The U.S. agricultural sector faces estimated annual losses exceeding $12 billion due to these tariffs, which are ultimately passed on to consumers, exacerbating inflation risks [7][8]. Global Trade Dynamics - The persistence of high tariffs distorts price signals and hinders global productivity, leading to long-term economic damage [8]. - In today's highly specialized and integrated global economy, the negative impacts of protectionism spread rapidly, disrupting global supply chains and hindering economic growth [8][9].
