Ultra-Processed Foods Linked to Worsening Psoriasis Flare-Ups

New research has established a significant link between ultra-processed foods (UPFs), such as potato chips, and flare-ups of psoriasis, a chronic skin condition. The study, based on data from the NutriNet-Santé cohort involving over 18,000 participants in France, indicates that individuals consuming high amounts of UPFs are more likely to experience active psoriasis cases. Even after adjusting for factors like body mass index (BMI) and alcohol consumption, the association remained strong, although no correlation was found in cases confirmed by dermatologists. Experts highlight that UPFs, high in refined sugars and unhealthy fats, may promote systemic inflammation and disrupt gut microbiota, exacerbating psoriasis symptoms. While the findings are compelling, some dermatologists emphasize the need for further research with dermatologist-validated cases to better understand the mechanisms involved and the potential for dietary modifications to mitigate psoriasis severity. sources

Coffee's Impact on Your Gut Microbiome Explained

Recent research indicates that coffee consumption may positively influence gut health by promoting the growth of the bacterium *Lawsonibacter asaccharolyticus*. A comprehensive study involving over 22,800 participants from the US and UK, alongside global data from nearly 54,200 individuals, found that coffee drinkers exhibited significantly higher levels of this bacterium—up to eight times more than non-drinkers. The study utilized advanced metagenomic techniques to analyze stool samples, revealing that even moderate coffee intake could enhance gut microbiome composition. While the exact health benefits of *L. asaccharolyticus* remain unclear, experts suggest it may be tied to coffee's known advantages, including lower risks of chronic diseases. Researchers advocate for further studies to explore this relationship and recommend moderate coffee consumption, ideally black or with minimal additions, as part of a healthy diet, while also highlighting other foods that may support similar gut health benefits. sources

Levothyroxine Linked to Bone Mass Loss, Study Finds

A recent study from Johns Hopkins University has raised concerns about the commonly prescribed thyroid medication levothyroxine, particularly among older adults. The research, presented at the Radiological Society of North America's annual meeting, found that the drug may lead to decreased bone mass and density in individuals aged 65 and older, even those with normal thyroid hormone levels. Over a six-year follow-up period involving 81 participants, those on levothyroxine demonstrated significant bone loss, suggesting a potential link to osteoporosis risk. Experts have long debated the appropriateness of levothyroxine prescriptions, with some arguing that hypothyroidism is often overdiagnosed in older populations. The findings underscore the need for careful monitoring and individualized treatment plans to mitigate side effects, including bone loss, as highlighted by medical professionals advocating for deprescribing in cases of adverse reactions. sources

Cardiovascular Drugs That May Reduce Dementia Risk

A recent study published in *Alzheimer’s & Dementia* has highlighted the complex relationship between cardiovascular medications and dementia risk. Analyzing data from over 88,000 dementia patients and 880,000 control participants, researchers found that long-term use (five years or more) of certain drugs, including antihypertensives, lipid-lowering medications, diuretics, and oral anticoagulants, is associated with a decreased risk of dementia. Conversely, the use of antiplatelet medications was linked to an increased incidence of dementia. The study raises important questions about the potential cognitive effects of these widely prescribed drugs, particularly antiplatelets, which may pose risks despite their cardiovascular benefits. Experts caution that the findings, derived from a Swedish population, may not be generalizable and emphasize the need for further research to confirm these associations and explore the underlying mechanisms. The implications for clinical practice are significant, particularly regarding the management of patients at risk for both cardiovascular disease and dementia. sources

Preserving Muscle Mass While Using Weight-Loss Drugs

The emergence of glucagon-like peptide-1 (GLP-1) drugs, such as Wegovy and Zepbound, has revolutionized weight management, prompting concerns over potential muscle mass loss during significant weight reduction. Experts highlight that while these medications effectively induce weight loss by mimicking GLP-1 hormone functions—stimulating insulin secretion and reducing hunger—they may also lead to muscle loss, particularly in older adults or those with pre-existing conditions like sarcopenia. Although studies indicate that muscle loss from GLP-1 treatments aligns with expected weight loss, maintaining muscle mass is crucial for long-term health and metabolic function. To mitigate muscle loss, experts recommend a protein-rich diet and regular resistance training. Monitoring body composition and consulting with healthcare professionals can further aid individuals in achieving sustainable weight loss while preserving muscle health. Future research may explore additional strategies and medications to prevent muscle loss associated with GLP-1-induced weight loss. sources
