Other studies have tried to pinpoint exactly what in caffeine is helping to halt the onset of these diseases. A 2014 study (14) found that caffeine blocks various tau receptors (a protein that contributes to brain cell degeneration). Another study found that caffeinated coffee increased GCSF (15) - a substance greatly decreased in Alzheimer’s patients - levels in the bloodstream.

Here’s a way to add a little seasonal flair to your caffeine routine while also supporting heart health and balancing blood sugar levels. (PSL, can you do that?)

Not only do you expose yourself to plastic that’s been heated, but Keurigs tend to get dirty, fast. “The water tanks in a Keurig can never truly be flushed and cleaned. We are concerned about mold and bacteria growth in these tanks over time, much like commercial ice machines,” Immer says.
This trick may seem obvious, but you would be shocked to learn just how many popular versions of coffee are loaded with artificial sweeteners and refined sugar. For example, a chai tea latte (found at a popular coffee store that shall not be named) has 15 more grams of sugar than a Snickers bar does! Even less obvious versions of sweetened coffee may be packed with artificial sweeteners or extra sugar. A salted caramel mocha (again, found at an unnamed coffee chain) hits your bloodstream with a whopping 56 grams (!) of sugar.
