Core Viewpoint - The latest research published in the journal Cell reveals that skipping breakfast can trigger a "metabolic memory" effect in the small intestine, leading to increased nutrient absorption efficiency and potentially contributing to obesity and atherosclerosis [6][7][9]. Group 1: Mechanisms of Nutrient Absorption - The small intestine operates through two independent nutrient supply pathways: luminal supply (food intake) and blood supply (internal reserves) [8]. - When breakfast is skipped, the small intestine shifts to an internal energy supply mode, activating a "metabolic compensation mechanism" that enhances nutrient absorption efficiency, particularly for cholesterol and fats [8][9]. - In mouse models simulating breakfast skipping, significant metabolic reprogramming occurs, including a nearly 40% increase in cholesterol absorption efficiency due to upregulation of key transport proteins [9][18]. Group 2: Consequences of Skipping Breakfast - Long-term skipping of breakfast leads to a "rebound absorption" effect, resulting in increased weight gain and metabolic disorders [13][15]. - Mice that regularly skip breakfast show elevated low-density lipoprotein cholesterol (LDL-C) levels, exacerbating lipid metabolism disorders and doubling the risk of atherosclerosis [18]. Group 3: Recommendations for Metabolic Health - Attempting to lose weight through hunger may backfire, as the small intestine's "super compensation absorption" can lead to greater fat accumulation [15]. - Regular breakfast consumption, particularly with a combination of protein and dietary fiber, can effectively reset absorption rhythms and stabilize metabolism [15].

Core Viewpoint - The recent study from Sun Yat-sen University highlights the significant role of greenspace in mitigating the global disease and economic burdens associated with non-communicable diseases (NCDs) [4][6]. Summary by Sections Non-Communicable Diseases (NCDs) - NCDs are the primary threat to global public health, causing 42 million deaths in 2021, which accounts for 75% of total global deaths [6]. - It is projected that from 2011 to 2030, NCDs will result in over $30 trillion in economic losses globally, imposing heavy burdens on families, healthcare systems, and society [6]. Importance of Greenspace - Greenspace, including forests, parks, and gardens, plays a crucial role in human health and disease prevention [6]. - Increased exposure to greenspace is associated with a reduced risk of various NCDs, such as cardiovascular diseases, diabetes, cancer, and mental health issues [6]. - The benefits of greenspace may stem from ecological, biological, psychological, and social pathways, including reduced air pollution and enhanced social cohesion [6]. Research Limitations and Gaps - Previous studies on the relationship between greenspace and NCDs have been limited to specific geographic areas, restricting the applicability of findings to broader populations [7]. - There is a lack of comprehensive research quantifying the potential health and economic benefits of increasing greenspace on a global scale [7][8]. Key Findings of the Study - The study analyzed data from 204 countries/regions between 2000 and 2021, using mixed-effects regression models to assess the association between greenspace and NCD-related mortality and disability-adjusted life years (DALYs) [8]. - Results indicate that larger greenspace areas correlate with lower burdens of NCDs [8]. - If greenspace had been maintained at optimal levels over the past two decades, it could have potentially prevented 1.66 million NCD-related deaths and 37.68 million DALYs, saving nearly $10 billion [8]. Implications for Policy - The findings provide invaluable information for policymakers and practitioners, suggesting that greenspace initiatives should be integrated into national policy-making and resource allocation to alleviate the disease and economic burdens of NCDs globally [10].

Core Viewpoint - The article discusses a groundbreaking research study that introduces a large language model (LLM)-based biological age prediction method, which estimates overall and organ-specific aging through health examination reports, aiming to enhance health management for the general public [3][4][5]. Group 1: Research Background and Importance - Accurately assessing an individual's aging level is crucial for identifying health risks and preventing age-related diseases, yet current aging indicators face methodological limitations and lack broad applicability [2][8]. - Aging is a major risk factor for mortality and chronic diseases, contributing significantly to societal health burdens, and understanding both overall and organ-specific aging is essential for comprehensive health assessments [7]. Group 2: Methodology and Framework - The research team developed a novel framework that converts health examination data (e.g., blood pressure, liver function) into textual reports for input into a large language model (e.g., Llama3), which analyzes numerous indicators to produce two key outputs: overall biological age and organ-specific ages for six major organs [10][11]. - The LLM does not rely on preset formulas but utilizes a pre-trained medical knowledge base to intelligently infer aging metrics based on individual health details [12]. Group 3: Validation and Results - The study validated its predictive framework using data from over 10 million individuals across six major databases, achieving impressive accuracy rates: 75.7% for predicting all-cause mortality risk, 70.9% for coronary heart disease risk, and 81.2% for liver cirrhosis risk, outperforming traditional models [15][20]. - The age difference predicted by the LLM correlates with increased health risks, with each additional year in predicted age raising all-cause mortality risk by 5.5% and coronary heart disease risk by 7.2% [16]. Group 4: Clinical Applications and Innovations - The research introduces a disease radar warning system, revealing that an increase in cardiovascular age difference correlates with a 45% increase in coronary heart disease risk, while liver age difference correlates with a 63% increase in liver cirrhosis risk [19]. - The study identifies 322 key proteins as potential "aging accelerators," with 56.7% being new targets linked to mortality risk, highlighting the predictive power of the LLM in personalized health management [19]. - By analyzing three years of continuous health examination data, the LLM can generate individual aging rate curves, improving disease outbreak predictions by three times compared to single examination assessments [19].
