What’s the link between coffee, tea and longevity?
Sometimes the simplest habits hide the most surprising health secrets. A new study from the UK Biobank suggests that a balanced mix of coffee, tea, and water may be linked to a longer life. Not too much, not too little. Just the right rhythm of sips. Personally, I was excited to read this since I drink coffee, tea and water throughout my day.
What The Researchers Found
Researchers asked thousands of people how many cups of coffee, tea, and water they drank each day. Then they followed them over time to see who lived longer. After adjusting for other lifestyle factors, they found something fascinating. People who drank about seven to eight drinks a day had the lowest risk of dying from any cause. When the total was more than four drinks, replacing some plain water with coffee or tea was linked to a lower risk of death.
The sweet spot seemed to be two cups of coffee and three cups of tea each day. People who drank that combination had lower risks of death from cancer, heart disease, respiratory illness, and digestive disease.
Why Coffee and Tea Might Help
Both coffee and tea are rich in natural plant compounds called polyphenols, which help protect cells from damage. They reduce inflammation and slow the kind of wear and tear that builds up over time.
Coffee has been linked to better liver health, improved blood sugar control, and a lower risk of some cancers. Tea, especially green and black tea, has been shown to support heart health and may help regulate cholesterol and blood pressure. And water, humble as it is, keeps everything in your body flowing smoothly.
Together, these drinks create a steady flow of hydration and protective compounds that might give your cells a little extra edge.
The Limitations
The researchers did not prove that coffee and tea make you live longer. They only found that people who drink them (along with water) tend to have lower death rates. The data came from self-reports, so people might have exaggerated or misremembered how much they actually drank. They also didn’t dive into how a person takes their coffee and tea: Plain? Added Sugar? Cream? That may impact outcomes. Further, caffeine affects everyone differently. For some, too much can cause anxiety, insomnia, or palpitations. I know that if I drink too much coffee, it will make me have to pee more-which can be annoying depending on what I’m doing that day. Still, I drink coffee daily for a few reasons: I’ve read other studies linking it to lower rates of cancer and increased longevity. I have asthma, so before I work out, I use black coffee as natural bronchodilator. Thirdly, I’ve experienced bouts of depression in the past, and anecdotally, coffee helps me avoid that cerebral mud pit. It also fuels my creativity. When I sit down to write, or make one of my Instagram/Tiktok videos, I always have coffee first.
The TakeAway
If you already enjoy coffee or tea each day, keep going, but stay balanced. Keep the sugar and heavy cream in check. I don’t care what anyone says, moderation has a great track record. That said (and I’m about to contradict myself here), I’d avoid those artificial sweeteners completely as they’ve been linked to myriad health issues. (No, correlation does not equal causation, but I can still modify my behavior and make decisions based on the correlations. ;))
Think of your daily drinks as a little orchestra. Coffee wakes up the morning. Tea brings calm focus to the afternoon. Water keeps the whole symphony in tune.
Science may not have found the fountain of youth (and probably never will without a list of problems that come with it) but the coffee-tea-water trio might add years to your life. I say, take the wins when you can. ;)
