Microplastics Found Clogging Human Arteries

Microplastics Found Clogging Human Arteries

[ad_1] Image by Getty / Futurism A new study has linked the presence of microplastics in artery-clogging plaque to a higher risk of heart disease and even death. From remote regions of Antarctica and layers of sediment untouched by humans to human hearts and even newborn human babies, microplastics are everywhere. But while it stands to reason that microscopic shards of chemical-laced fossil fuel polymers finding their way into every imaginable corner of life probably wasn’t great, there hadn’t yet been an established link to its measurable impacts on the human body. Until now, that is. Published this week in The New England Journal of Medicine, the “landmark” study, conducted by a team of Italian researchers, is the first of its kind to establish a connection between the presence of microplastics in the human body and its impact on human health. According to the research, this was also the first time that microplastics were discovered in artery-clogging plaque at all. “This is a landmark trial,” Robert Brook, a physician-scientist at Wayne State University who studies …

Too Much Protein Actually Damages Your Arteries, Scientists Find

Too Much Protein Actually Damages Your Arteries, Scientists Find

[ad_1] Image by Getty / Futurism Meat enthusiasts are screaming “Where’s the beef?” after a new study came out in Nature Metabolism that suggests that eating excessive amounts of protein is bad for your arteries. Researchers at the University of Pittsburgh School of Medicine came to this conclusion after they analyzed biological data from human participants who ate protein, in addition to studying cellular behavior in petri dishes.  They found that eating over 22 percent of daily dietary calories from protein can activate macrophages, a type of immune cell, to increase the process of atherosclerosis, which is the hardening of arteries due to build up of cholesterol and fat in your artery walls. Atherosclerosis is bad because it can lead to heart attacks and strokes. Macrophages play a key roll in the formation of artery plaque. Researchers also found that a particular amino acid, leucine, “as the key activator” for the immune cell-to-atherosclerosis pathway. “Our study shows that dialing up your protein intake in pursuit of better metabolic health is not a panacea,” said Pittsburgh professor …
