A new study has linked more than 124,000 preventable, premature deaths in the United States over two years to the adverse health effects of consuming ultra-processed foods (UPFs). The study, led by Brazilian researchers, analyzed data on UPF consumption from several countries, including the United States, the United Kingdom, Australia, Brazil, Canada, Colombia, Chile, and Mexico. To calculate the impact, the authors developed a comparative risk assessment, examining the relationship [...]

A new study, published in the journal Neurology, has found that heavy alcohol consumption is linked to a greater risk of a specific type of brain damage tied to memory and cognitive decline. Researchers analyzed brain autopsies from 1,781 individuals who died at an average age of 75. In addition to examining brain tissue for signs of damage including hyaline arteriolosclerosis (a lesion associated with memory issues) and tau tangles (linked to Alzheimer's disease), they also gathered [...]

In a recent study conducted jointly by researchers in Germany and Brazil, it was discovered that 8 out of 15 adults examined post-mortem had microplastics present in their olfactory bulbs, which are the brain's region responsible for smell. This revelation, published in JAMA Network Open, points to the likelihood that these particles were inhaled over many years, given that microplastics are widely dispersed in the air. Thais Mauad, the lead author and an associate professor of [...]

A recent study led by MIT and published in the journal Nature has revealed that fasting followed by refeeding, known as intermittent fasting, can enhance cell regeneration in the intestines, but could also raise the risk of developing intestinal tumors. Researchers examined the gut stem cells of three groups of mice: a control group that ate normally, a group that fasted for 24 hours, and a group that fasted for 24 hours followed by unlimited feeding for another 24 hours. They observed that [...]
