Drinking Coffee Can Be Good for You, but a New Study Suggests There’s a Limit
In recent years, plenty of studies have suggested that drinking coffee can be good for you, and can even help you live longer. But coffee addicts take note: for the first time, researchers have identified the limit for how much coffee you can have before it puts your health at risk.
Drinking six or more cups of coffee per day may increase your risk of cardiovascular disease and outweigh other benefits, researchers from the University of South Australia found in a new study published in the American Journal of Clinical Nutrition.
"In order to maintain a healthy heart and a healthy blood pressure, people must limit their coffees to fewer than six cups a day — based on our data six was the tipping point where caffeine started to negatively affect cardiovascular risk," co-author Elina Hyppönen of the Australian Centre for Precision Health said in a press release.
The study examined the health records and diets from the UK Biobank of nearly 350,000 people between 37 and 73 years old, as well as which of the participants had a gene variant, CYP1A2, which allows those who possess it to metabolize caffeine faster than those who do not. The levels of coffee consumption were likely self-reported, according to The Takeout, which noted that many people don't consider that 16-ounce travel mugs count as more than one cup of coffee.
Participants who drank six or more cups of coffee were 22 percent more likely to develop heart disease compared with those who only had two cups at most per day, regardless of whether or not they possessed the CYP1A2 gene variant. The researchers indicated this could be because excess caffeine consumption can lead to high blood pressure, which often precedes heart disease. The World Health Organization lists cardiovascular disease as the leading global cause of death, despite its preventability.
But the researchers also found that those who preferred decaf or didn't drink any coffee weren't much better off. Compared to those with moderate daily coffee consumption, decaf drinkers had a 7 percent higher rate of heart disease and non-coffee drinkers had an 11 percent higher rate of heart disease.
This jibes with previous research suggesting that the antioxidants in coffee could reduce the risk of heart disease, stroke and diabetes at the right levels of consumption, which might be around 400 mg per day, Health.com reported. In 2018, a German study also found that as much as four-to-five cups of espresso per day could improve heart health by making proteins in older blood vessel cells of mice and human tissues perform like younger ones.
The authors of this new study say that, as is often the case, moderation and knowing your limits is essential to your health.
"Most people would agree that if you drink a lot of coffee, you might feel jittery, irritable or perhaps even [nauseated] — that's because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being," Hyppönen said.

Over the last month, I've seen a number of opinion articles attacking electric vehicles (EVs). Sadly, this comes as no surprise: now that the Biden administration is introducing federal policies to accelerate the roll out of electric vehicles, we were bound to see a reaction from those that oppose reducing climate changing emissions and petroleum use.
The majority of EVs sold in 2020 were models with a starting price (Manufacturers Suggested Retail Price) under $40,000 and only a fifth of models had a starting price over $60,000.
On Friday, China set out an economic blueprint for the next five years, which was expected to substantiate the goal set out last fall by President Xi Jinping for the country to reach net-zero emissions before 2060 and hit peak emissions by 2030.
The Great Trail in Canada is recognized as the world's longest recreational trail for hiking, biking, and cross-country skiing. Created by the Trans Canada Trail (TCT) and various partners, The Great Trail consists of a series of smaller, interconnected routes that stretch from St. John's to Vancouver and even into the Yukon and Northwest Territories. It took nearly 25 years to connect the 27,000 kilometers of greenway in ways that were safe and accessible to hikers. Now, thanks to a new partnership with the Canadian Paralympic Committee and AccessNow, the TCT is increasing accessibility throughout The Great Trail for people with disabilities.

Alexa Fernando<p>This partnership also comes at a time when access to outdoor recreation is more important to Canadian citizens than ever. <a href="https://www150.statcan.gc.ca/n1/daily-quotidien/200527/dq200527b-eng.htm" target="_blank" rel="noopener noreferrer">Studies from the spring of 2020</a> indicate that Canadian's <a href="https://www.bnnbloomberg.ca/moneytalk-mental-health-during-covid-19-1.1567633" target="_blank" rel="noopener noreferrer">mental health has worsened</a> since the onset of social distancing protocols due to COVID-19. </p><p>The <a href="https://www.mayoclinic.org/diseases-conditions/coronavirus/in-depth/safe-activities-during-covid19/art-20489385" target="_blank" rel="noopener noreferrer">Mayo Clinic</a> lists hiking, biking, and skiing as safe activities during COVID-19. Their website explains, "When you're outside, fresh air is constantly moving, dispersing these droplets. So you're less likely to breathe in enough of the respiratory droplets containing the virus that causes COVID-19 to become infected."</p><p>TCT leadership took this into consideration when embarking on the accessibility project. McMahon explains that there has never been a more important time to bring accessibility to the great outdoors: "Canadians have told us that during these difficult times, they value access to natural spaces to stay active, take care of their mental health, and socially connect with others while respecting physical distancing and public health directives. This partnership is incredibly important especially now as trails have become a lifeline for Canadians."</p><p>Together, these organizations are paving the way for better physical and mental health among all Canadians.
