Study: Many toxic chemicals enter body via food packaging
Publicado em 17 setembro 2024
Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb.
The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the air.
Although microplastics have already been found in human lungs, intestines, liver, blood, testicles and even semen, it had long been thought that the body's protective blood-brain barrier might keep the [...]

Study: Breathing might bring microplastics into brain
Publicado em 16 setembro 2024For the first time, scientists have detected microscopic microplastics lodged in the human brain. Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb. The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the air.

Type 2 diabetes linked to diet of too many 'bad' carbs, too much meat
Publicado em 18 abril 2023Most cases of Type 2 diabetes can be linked to making poor food choices, a new study finds. Researchers from Tufts University in Boston linked poor diet to 14 million cases of Type 2 diabetes -- about 70% of new diagnoses globally -- in 2018. The biggest impact came from insufficient intake of whole grains, too much refined rice and wheat, and overconsumption of processed meat. "Our study suggests poor carbohydrate quality is a leading driver of diet-attributable Type 2 diabetes [...]ver notícia -
Study shows brain changes after COVID-19 infection, even in mild cases
Publicado em 21 fevereiro 2023People who are experiencing anxiety and depression months after a mild case of COVID-19 may have changes affecting the structure and function of their brains, Brazilian researchers report. "There is still much to learn about long COVID, which includes a wide range of health problems, including anxiety and depression, months after infection," said Dr. Clarissa Yasuda of the University of Campinas in São Paulo. "Our findings are concerning, as even people with a mild [...]ver notícia -
Ring discovered around dwarf planet confuses astronomers
Publicado em 08 fevereiro 2023Feb. 8 (UPI) -- Astronomers have discovered a ring around a dwarf planet called Quaoar in the outer reaches of the solar system. The ring was found at seven and a half times the radius of Quaoar, much farther away from a planet than is usual. The finding was made during an occultation event, when a planet passes directly in front of a star, allowing the space-based telescope Cheops to observe its silhouette. "When we put everything together, we saw drops in brightness [...]ver notícia -
Study: Dieters with diabetes should set aside steak, but can eat mashed potatoes
Publicado em 21 setembro 2022Sept. 21 (UPI) -- Dieting by cutting protein intake may be as effective as restricting calories for people trying to fight obesity, diabetes and high blood pressure, a small study suggests. So, that means setting aside the steak, but passing the mashed potatoes. The study by researchers in Brazil and Denmark, which compared the effects of protein and calorie restriction diets in patients with metabolic syndrome, was published in the journal Nutrients. They said their [...]ver notícia -
