How Coffee Caffeine Affects Your Health

Studies concerning the health effects of coffee and caffeine have grown apace in the last twenty-five years or so. One effect of this phenomenon was that health workers systematically warned the public that consuming the drink habitually may be unsafe. Reports that are more recent indicate, nevertheless, that coffee might in reality be more beneficial than detrimental to health. That should be great news for the innumerable folks throughout the world that consume it.

Caffeine, amongst the main ingredients in coffee, has long been known to be a moderate stimulant that can increase blood pressure, increase heart rate and be the cause of the occasional irregular heartbeat. Even so, the majority of researchers now consider the effect is mild and short-lived.

What they are progressively recognizing from empirical information is that coffee is a drink that has an assortment of possible health benefits to offer. There is evidence, for example, that coffee reduces the risk for colon cancer if drunk at the rate of four cups per day. All the same, that is not the most salutary consequence you can cite considering that intake at such an amount can easily result in greater ills. Nevertheless, there are additional, more pertinent findings that depict coffee, even at moderate levels of consumption, as a protagonist instead of a culprit in human health.

Like wine, coffee has antioxidants that eliminate radicals in the blood and consequently lower the risk of heart disease and several forms of cancer. Several studies showed that the concentration of antioxidants in coffee is greater than that in tomatoes, apples or cranberries. Some scientists point out, nonetheless, that fruits and vegetables have an advantage, as far as being sources of essential vitamins, minerals and fiber is concerned.

Research studies from China present strong evidence that coffee can lessen the effects of Parkinson’s disease. A couple of scientific reports, one from the United States and the other from Scandinavia, show that both decaffeinated and regular coffee diminish the odds of developing the symptoms of type 2 diabetes mellitus.

Positive effects of coffee on the digestive system have been noted too. There is reason to believe from available data that coffee may lessen the risks of developing calculi (stones) in the kidney and the gallbladder. Caffeine is also known to cause the secernment of stomach acids, that improves digestion, or the breakdown of solid food.

Caffeine has been demonstrated to alleviate tightness of respiratory tracts in asthmatic people, if consumed in moderation. An additional important element of coffee, theophylline, adds to this therapeutic effect by behaving as a bronchodilator.

Nonetheless, those benefits, unsuprisingly, come with risks. Even though mammalian spermatozoon swim quicker, longer and farther in fluids that contain traces of coffee, many studies link heavy coffee consumption with reduced fertility. Increased coffee consumption has been associated with higher blood levels of homocysteine, recently established to be a risk factor for coronary heart disease. Other studies show an increase in detrimental LDL-cholesterol. To what degree these elements really contribute to heart attacks are a matter of debate.

Most coffees made by the European way of boiling ground beans contain cafestol, a  substance claimed to have the effect of raising the levels of cholesterol in humans. Many Americans, however, prefer their coffee percolated or filtered, processes that get rid of cafestol, except in the case of decaf coffee beans .

Women coffee drinkers have been discovered to have lower calcium levels and bone mineral densities when compared with non-consumers. What is more, those that take four or more cups per day increase their risk of contracting urinary incontinence.

In the main, though, the majority agree that the benefits, at least at moderate consumption levels, outweigh the dangers. Incidentally, for those heavy drinkers looking for an alternative, colas comprise one-third the quantity of caffeine per ounce. Somehow though, drinking a Coke instead of a Latte does not seem worth the chance.
