Research has revealed that regular coffee drinkers can reduce their risk of having a stroke. In women, it seems to lower the risk of heart diseases. It may increase your blood pressure temporarily, but that does not mean a stroke or heart disease is inevitable. It can often work to clear out the system and keep your heart functioning at an optimal level. A study also shows that coffee helps cure arrhythmias, which is abnormal heart rhythms.
Coffee beans have important nutrients like the B-family vitamins, including riboflavin, pantothenic acid, and niacin, as well as other nutrients like potassium, manganese, and magnesium. Perhaps most importantly, they contain antioxidants and caffeine, which have a wide range of health benefits when consumed in moderation and at right times during the day.
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.
