The latest research supports the conclusion that, for most adults, consuming up to 400 mg of caffeine a day (or up to five 8-ounce cups of caffeinated coffee per day) is safe and appears to be linked to a lower risk of cardiovascular disease for some individuals. However, higher doses of caffeine, such as levels found in energy drinks including energy shots, may cause cardiovascular harm, according to a new American Heart Association scientific statement, "Caffeine and Cardiovascular Disease," published today in the journal Circulation. https://medicalxpress.com/news/2026-07-coffee-heart-health-cups-caffeinated.html Mon, 20 Jul 2026 05:00:01 EDT news703505779 New research published in The American Journal of Preventive Medicine and presented at this year's International Congress on Obesity (ICO 2026), hosted by the World Obesity Federation (WOF) in Mexico City, Mexico (July 15–17), suggests that 23%-38% of all cardiovascular deaths and 23%-37% of all cases of cardiovascular disease (coronary heart disease and stroke) are attributable to ultra-processed food (UPF) consumption. https://medicalxpress.com/news/2026-07-heart-deaths-disease-due-ultraprocessed.html Thu, 16 Jul 2026 11:20:11 EDT news703407563 The common rationale for drinking water at meals is that it physically stretches the stomach, triggering fullness so you don't eat too much. But a new Cornell study found no support for that idea in practice. The paper is published in the journal Appetite. https://medicalxpress.com/news/2026-07-common-diet-intake-spicy-foods.html Thu, 16 Jul 2026 10:20:04 EDT news703407242 Women should ignore most of the exercise advice they see on social media, University of Otago – Ōtākou Whakaihu Waka researchers say. https://medicalxpress.com/news/2026-07-debunks-women-advice.html Wed, 15 Jul 2026 14:20:01 EDT news703338642 If you've been reaching for chips, mayonnaise or salad dressing labeled "made with avocado oil," there's a good chance the oil inside isn't pure avocado oil, despite it being the only listed oil ingredient. University of California, Davis, researchers tested processed foods marketed as containing avocado oil. They found 48 of the 54 avocado oil-labeled products were adulterated with cheaper oils. The study was published in Applied Food Research. https://medicalxpress.com/news/2026-07-avocado-oil-chip-youre-pure.html Wed, 15 Jul 2026 11:40:08 EDT news703328823 A high-fat, low-carbohydrate diet, also called a ketogenic diet, can help some people lose weight by forcing their bodies to burn fat for fuel instead of sugar. https://medicalxpress.com/news/2026-07-ketogenic-diets-cancer-small-intestine.html Wed, 15 Jul 2026 11:00:31 EDT news703263320 The world's "heritage" diets could hold vital clues to better health.

Nutritional choices among populations in countries such as Greece, Spain and southern Italy are moving away from their traditional dietary habits even as the Mediterranean diet gains popularity around the world, according to a new review by researcher Domenico Praticò, M.D., a professor in the Department of Neural Sciences at the Lewis Katz School of Medicine at Temple University. https://medicalxpress.com/news/2026-07-mediterranean-diet-paradox-reveals-shifting.html Tue, 14 Jul 2026 11:30:01 EDT news703246246 A metabolic byproduct formed when gut bacteria break down dietary fiber appears to protect against dangerous fungal infections common in immunocompromised patients, a study led by UT Southwestern Medical Center researchers shows. The findings, published in Cell Host & Microbe, could lead to new therapies to shield this vulnerable population from Candida albicans, a leading human fungal pathogen. https://medicalxpress.com/news/2026-07-metabolites-gut-bacteria-fungal-infection.html Tue, 14 Jul 2026 10:40:08 EDT news703241776 Xanthan gum is found almost everywhere.

Scientists, however, have discovered that whether someone is an early bird who wakes up early and starts the day with energy or a night owl who naturally stays up late and wakes up later is far more than a lifestyle choice. This pattern reflects the body's natural preference for the timing of sleep and wake cycles within a 24-hour day. https://medicalxpress.com/news/2026-07-night-owls-nutritious-food-belly.html Sun, 12 Jul 2026 11:20:04 EDT news702896030 A new systematic review has found that both the way a baby is born and exposure to antibiotics around the time of birth could be linked to differences in the development of the infant gut microbiome. The review also found that exclusively breastfeeding babies born by cesarean section or exposed to antibiotics may reduce these differences. https://medicalxpress.com/news/2026-07-birth-method-antibiotics-babies-gut.html Thu, 09 Jul 2026 16:30:01 EDT news702822125
