Published in BMC Medicine, the research indicates that higher urinary levels of polyphenol metabolites correlate with lower cardiovascular disease risk scores and increased HDL "good" cholesterol. While the study cannot definitively establish causation, it suggests that diets rich in these foods may promote better heart health, particularly as individuals age. Dr. Cheng-Han Chen, an interventional cardiologist, emphasized the importance of dietary research in managing heart disease risk factors. Nutritionist Monique Richard recommends simple dietary changes, such as incorporating more fruits, vegetables, and whole grains, to enhance polyphenol intake. She encourages gradual shifts toward plant-based foods to support overall health, including heart, gut, and brain function. 
Published: Dec 16 2025, 12 ameznews.inA recent study has found that GLP-1 medications, commonly used for weight loss and diabetes management, likely have little to no impact on the risk of obesity-related cancers, including thyroid, pancreatic, breast, and kidney cancers. The research, which analyzed data from 48 trials involving over 94,000 participants, aimed to address long-standing safety concerns surrounding these drugs. While previous observational studies suggested potential links between GLP-1 use and lower cancer rates, this new analysis indicates that any protective effects remain uncertain, particularly due to short follow-up periods. Experts emphasize the need for continued long-term monitoring to fully understand the implications of GLP-1 drugs on cancer risk. As obesity rates continue to rise globally, the findings highlight the importance of understanding both the benefits and potential risks of these medications in managing weight and related health issues.
Published: Dec 15 2025, 2 pmeznews.inA new observational study from Japan suggests that cheese consumption may be associated with a modest reduction in dementia risk. Researchers found that among 7,914 participants, those who reported eating cheese had a 1.06 percentage point lower likelihood of developing dementia over three years compared to non-cheese eaters. While the study's findings are statistically significant, the authors caution against drawing direct causal conclusions, as the majority of participants consumed processed cheese, and Japan's low baseline cheese intake may exaggerate the observed effects. Experts emphasize that while small amounts of cheese can fit into a brain-healthy diet, excessive consumption, particularly of high-sodium and high-fat varieties, could pose health risks. The study highlights the potential neuroprotective benefits of dairy but underscores the importance of moderation and dietary context. The research was published in the journal Nutrients and funded by the Meiji group, a Japanese dairy company.
Published: Dec 14 2025, 1 pmeznews.inA recent study published in *Aging Cell* reveals that a significant long-term reduction in caloric intake may slow brain aging, as evidenced by research on rhesus monkeys conducted by Boston University and the National Institute on Aging. Monkeys that consumed 30% fewer calories over 20 years demonstrated improved brain health, with enhanced glial cell integrity and neuronal connectivity compared to those on a standard diet. Although these findings suggest calorie reduction could help maintain cognitive function in humans, experts caution against extreme dietary restrictions. Michelle Routhenstein, a preventive cardiology dietitian, emphasizes that a more feasible approach involves modest reductions of 10-20% combined with nutrient-dense foods and regular physical activity. The study highlights the complex interplay of various factors influencing brain aging, including genetics and lifestyle, while indicating that calorie restriction may mitigate age-related cellular dysfunction.
Published: Dec 13 2025, 1 pmeznews.inA recent study published in *Sleep Advances* has highlighted the critical role of sleep in determining life expectancy, finding that insufficient sleep has a more detrimental impact on longevity than diet, exercise, and social connections. Researchers, led by Dr. Andrew McHill from Oregon Health & Science University, discovered strong correlations between inadequate sleep and reduced life expectancy across various U.S. states from 2019 to 2025. Approximately 16% of the global population suffers from insomnia, with many Americans reporting insufficient sleep. Experts emphasize that sleep is a biological necessity, akin to diet and exercise, urging individuals to prioritize it. Recommendations for improving sleep quality include creating a conducive sleep environment, maintaining a consistent sleep schedule, and limiting exposure to blue light before bedtime. The findings underscore the importance of addressing sleep issues as a fundamental aspect of health and wellbeing.
Published: Dec 13 2025, 12 ameznews.inA recent study published in the journal *Aging* suggests that theobromine, a compound primarily found in chocolate, may play a role in slowing biological aging. Researchers analyzed blood samples from 1,669 participants and discovered that those with the highest levels of theobromine exhibited epigenetic markers indicative of slower aging processes. While the findings are preliminary, experts advocate for further investigation, as theobromine is a gentler stimulant compared to caffeine and is generally safe for human consumption. The study emphasized the importance of epigenetic changes in aging and utilized advanced methodologies like the GrimAge clock to assess biological age. However, questions remain about other compounds in chocolate, such as flavan-3-ol, which may also contribute to these effects. Health professionals stress that choosing high-quality dark chocolate with minimal additives may offer health benefits, supporting the notion that chocolate can be part of a healthy diet.
Published: Dec 12 2025, 12 pmeznews.inA recent study published in JAMA Network Open has highlighted a concerning association between Restless Leg Syndrome (RLS) and an increased risk of developing Parkinson's disease. Conducted in South Korea, the population-based cohort study analyzed over 1 million individuals, identifying 9,919 with RLS who had documented outpatient diagnoses. Findings indicated that those with RLS had a higher incidence of Parkinson’s disease, with a quicker diagnosis rate over a 15-year period. Interestingly, participants treated with dopamine agonists exhibited a lower risk and delayed onset of Parkinson's compared to untreated individuals. However, the study has limitations, including potential misdiagnosis and the inability to establish causation. Experts caution that while RLS may serve as a risk factor for Parkinson's, the relationship remains complex, necessitating further research to explore the neuroprotective effects of dopamine treatments and the underlying mechanisms connecting the two conditions.
Published: Dec 11 2025, 3 pmeznews.inRecent research highlights dietary patterns that may significantly reduce the risk of developing type 2 diabetes, a condition that has seen an 18.6% increase in prevalence in the U.S. over the past decade. Studies from 2025 indicate that adherence to the DASH diet can lower diabetes risk by 23%, while the AHEI and Mediterranean diets offer reductions of 21% and 17%, respectively. The DASH diet, originally designed to combat hypertension, is noted for its high potassium, magnesium, and fiber content, which also benefits those with diabetes. Additionally, consuming three to five cups of coffee daily has been associated with lower mortality rates and reduced diabetes risk. Furthermore, a recent study suggests that high phytosterol intake, found in nuts and whole grains, may decrease heart disease and diabetes risk by 9% and 8%, respectively, by improving insulin sensitivity and reducing inflammation.
Published: Dec 10 2025, 2 pmeznews.inIn 2024, approximately 1.4 billion people worldwide were affected by hypertension, a leading risk factor for heart disease and stroke. While factors like genetics and ethnicity are unchangeable, dietary habits can significantly influence blood pressure. Recent research published in the American Journal of Hypertension suggests that daily multivitamin supplementation may help mitigate hypertension risk, particularly in older adults with poor dietary quality. The study, which involved nearly 8,900 participants aged 60 and above, indicated that those with insufficient nutrient intake, such as potassium and magnesium, could benefit from multivitamins. However, no significant effects were observed on blood pressure among those with healthier diets. Researchers emphasize the need for further studies to explore the relationship between diet quality and multivitamin efficacy across diverse populations. This research highlights the potential of simple dietary interventions in addressing hypertension, a critical public health concern.
Published: Dec 09 2025, 6 pmeznews.inA recent study presented at the Radiological Society of North America (RSNA) annual meeting has found that obesity may accelerate the progression of Alzheimer’s disease by increasing the buildup of amyloids and related blood biomarkers. Researchers from Washington University School of Medicine in St. Louis analyzed 1,228 plasma samples from 407 participants, revealing that individuals with obesity experienced faster increases in proteins linked to Alzheimer’s, such as P-tau217 and neurofilament light chain (NfL), over time. While no significant differences were noted at baseline, the long-term data indicated that obesity correlates with a quicker rise in these biomarkers, suggesting that weight management could be a crucial strategy in slowing Alzheimer’s progression. Experts emphasize the need for further research into the implications of obesity on Alzheimer’s pathology and the potential benefits of weight-loss interventions. However, the study has limitations, including a lack of diversity among participants and the focus on late-life obesity.
