| |  | | |  Older adults who consistently followed healthy dietary patterns, especially AHEI, MIND, and AMED, accumulated chronic diseases more slowly over 15 years. Diets high in pro-inflammatory foods were linked to a faster buildup of multimorbidity, particularly in cardiovascular and neuropsychiatric conditions. | | | | |  Long-term gluten reduction may disrupt gut microbiota balance, reducing beneficial bacteria and increasing ethanol, linked to inflammation and metabolic risks. | | | | |  A crossover trial in healthy young adults found that both lean chicken and beef diets reduced gut microbial richness, but only chicken caused significant diversity loss. The study highlights that lean local beef may have a milder impact on the gut microbiome than chicken. | | | | |  Researchers have discovered a novel gut-brain sensory circuit in mice where specialized colonic cells sense bacterial flagellin and rapidly suppress feeding via the vagus nerve. This "neurobiotic sense" operates independently of immune pathways, revealing a direct neural mechanism for microbiota-host communication. | | | | |  A major scoping review of recent systematic reviews and meta-analyses finds that most dairy products are either neutral or modestly protective for heart, cancer, metabolic, and mortality outcomes in adults. Yogurt and other fermented dairy consistently show the strongest health associations, while some risks remain for specific cancers. | | | | |  Research indicates that early eating habits may lower genetic obesity risk, enhancing weight loss maintenance in at-risk adults after dietary treatments. | | | | |  There is broad consensus that the overall body of evidence shows lowering LDL (low-density lipoprotein) cholesterol provides both statistically significant and clinically meaningful benefits in treating and preventing cardiovascular disease. | | | | |  A healthy diet can slow down the accumulation of chronic diseases in older adults, while inflammatory diets accelerate it. | | | | |  A nationwide Austrian study of nearly 9,000 teens reveals distinct health behaviors and motivations among vegetarian, vegan, and omnivorous students. Vegan and vegetarian youth are more likely to report higher fruit, vegetable, and activity levels, but still fall short of daily exercise targets. | | | | |  New research links ultra-processed food intake to increased diabetes risk in individuals with depression, highlighting the need for healthier dietary choices. | | | | |  This article examines how oral collagen supplements affect skin, joint, and muscle health by reviewing the latest clinical research. It also discusses the mechanisms, sources, safety, and limitations of collagen supplementation. | | | | |  L-theanine, an amino acid found in green tea, may help reduce stress, improve sleep quality, and support cognitive performance in healthy adults. Evidence from clinical studies shows it is safe and well-tolerated, but further research is needed to confirm its benefits for anxiety disorders. | | | | |  Fortina Hernández is called "the one who knows it all." For more than two decades, the community health worker has supported hundreds of families throughout southeast Los Angeles by helping them sign up for food assistance, sharing information about affordable health coverage, and managing medications for their chronic illnesses. | | | | |  Malnutrition is on a dangerous trajectory in the Gaza Strip, marked by a spike in deaths in July. | |
