Is too much coffee good for you?

Coffee and health, it’s not black and white

Middle Easterns love their coffee and they love it strong. Brew it by the spoonful in a cup or boil it in a finjan. It’s a great morning treat. And it helps bring on a bowel movement when particulary strong. But how much coffee is good coffee? Can overdoing it ever be bad?

Drinking three to four cups of coffee a day can positively impact health more than it can harm it, according to a recent study. Pour yourself a cup, and read on.

Health researchers looked at more than 200 previous studies and concluded that coffee can be a preventative for certain health conditions including cardiovascular disease, Parkinson’s disease, depression, dementia, some cancers, type 2 diabetes and liver disease.  They also linked coffee consumption to lower risk of premature death.

Earlier this year, Spanish researchers reported 20,000 people who drank at least four cups of coffee a day had a 64% lower risk of death than those who never or almost never drank coffee. Two studies published in the Annals of Internal Medicine in July also connected coffee consumption to a longer life.

An editorial by Eliseo Guallar from the Johns Hopkins Bloomberg School of Public Health in Baltimore, Md., said there is no way to know if coffee prevents chronic disease and reduces mortality because there are too many factors to consider such as why people start drinking coffee and what kind of coffee drinks they’re drinking. Are you drinking coffee with half a cup of cream and 4 spoons of sugar? The author did remark that doctors should not recommend drinking coffee to prevent disease and people should not start drinking coffee to improve health.

Consumption of caffeine in other forms was not included as part of the study, as example caffeine-loaded energy drinks or black and white tea.  In 2017, an American teenager died after ingesting the caffeine from a large Diet Mountain Dew soft drink, a cafe latte from McDonald’s, and an energy drink over the course of about two hours.

Cause of death was a “caffeine-induced cardiac event causing a probable arrhythmia,” according to the coroner report.

“Most people can safely take in about 400 milligrams of caffeine daily or about 4 cups of coffee,” according to Robert Glatter, an emergency physician at Lenox Hill Hospital in New York City. Limits do vary from person to person

While many may worry that their caffeine consumption could put them at risk, the average person who drinks a cup or two of coffee has nothing to worry about.

He noted that children should limit caffeine consumption, and caffeine and alcohol should not be mixed.

“Mixing caffeine with alcohol is a dangerous practice because it may lead to higher levels of alcohol consumption as the person often believes and feels they are more alert,” he said. “The risk of alcohol poisoning increases as people consume more alcohol because they feel the caffeine will keep them awake and alert.”

Everyone is different, and some may experience side effects after a cup of coffee, while others may be able to drink five cups with no issue. Glatter stated, “It would likely take anywhere from 50-100 cups of coffee to result in a lethal dose of caffeine. That said, pure powdered caffeine can be lethal if a teaspoon of it is consumed at once. The recommended dose of powdered caffeine in this form is just 1/16th of a teaspoon.”

While many may worry their caffeine consumption from coffee and tea could put them at risk, the average person who drinks a cup or two of coffee has nothing to worry about.
