How much coffee is too much to drink a day?

How much coffee is too much to drink a day?

Coffee stores stay busy all day long, and I know people who drink many cups of coffee every day.

Similarly, a study from the U.S. found that participants who consumed a cup of coffee per day were 12 per cent less likely to die compared to those who didn't drink coffee.

That's because too much caffeine can cause high blood pressure, a precursor to heart disease, researchers say.

It's a question Dr Labos has addressed before, in an op-ed for the Montreal Gazette in 2014, in which he broke down various studies on the risks of caffeine after the FDA issued a warning about caffeine consumption. According to the World Health Organization, cardiovascular disease is the leading cause of death worldwide, yet it's also one of the most preventable.

This is the first time an upper limit has been placed on safe coffee consumption and cardiovascular health.

A previous study, published in the Annals of Internal Medicine, found that besides making us feel a little wired, drinking three cups of coffee a day could add years to our lives.

Moderate coffee consumption of two to four cups a day was associated with reduced mortality.

So as to keep up a strong heart and a sound circulatory strain, people must restrain their coffee less than six glasses per day, analysts said.

Fortunately for us, numerous studies have revealed that coffee can be good for our health in many ways - at least potentially helping to protect us from multiple sclerosis, Parkinson's disease, type 2 diabetes, cirrhosis of the liver, and Alzheimer's disease, among other afflictions. They also found that their conclusions were independent of genetics-meaning those who are highly sensitive to the effects of caffeine were just as likely to develop heart disease over the six-cup limit as those who can drink a triple espresso without getting jittery. They found also found that despite the ability of the caffeine-metabolizing gene CYP1A2 to process caffeine better and more quickly, it doesn't mean that individuals who carry this gene can consume more coffee without detrimental effects. In fact, the researchers also found that participants who didn't drink coffee at all-and those who drank decaf-also had higher rates of heart disease (11% and 7% higher, respectively) than those who drank one to two cups per day. Irrespective of the cause, nutritional concerns need to be addressed in this condition in order to prevent morbidity and mortality.

"As with many things, it's all about moderation; overindulge and your health will pay for it".
