What to know about a new study on coffee, tea, caffeine, and dementia risk. In this morning's Health Watch, we're looking at a new study that finds
that a daily cup of coffee or tea may help reduce your risk of dementia. CBS News medical contributor Dr. Celine Gonder is joining us right now to break it all down.
She's the public health editor at KFFF Health News. Good morning. Good morning. Okay, so this study took 40 years with more than 130,000 adults.
What did they find? Okay, so first of all, studies like this make me nervous. A cup of coffee a day is good for you. A cup of coffee a day. I know
That's what I was saying. I'm so glad you're acknowledging the health clickbait. It's health clickbait. It really is. And the problem is that the health clickbait makes people lose faith in people like me,
people like you who are talking about these studies. So the problem with this study is that, as you said, it's a large number of people.
They followed people for over 40 years. They found that if you drink two to three cups of coffee a day or one or two cups of tea a day, you have a relatively lower risk of dementia than people who do not.
non-caffeinated beverages or decaf coffee, but the risk and the reduction were really small, about half a year of cognitive age. And there are a lot of ways that could have happened in the study.
So I'm sitting here drinking tea, which I always do. I was thinking, do I need to switch to coffee? But you're saying be careful how you interpret that?
Take that with a big grain of salt. Salt. Yeah, right. So, one way that this kind of study can link is who drinks what kind of drinks.
So, for example, people might switch from regular caffeinated to decaf coffee for health reasons. So, for example, high blood pressure. Know that caffeine can raise your blood pressure.
Oh, high blood pressure is also a risk factor for dementia. So what you're really getting at in a study like this is people who don't make this switch.
That caffeinated beverages like coffee are protecting you. And tea has caffeine, too. So, of course, the question becomes, is this not the best way to protect yourself from dementia?
Medically speaking there are probably other ways that you can do things that you can do to protect yourself from dementia. Yeah. And before I get to that,
Um, what's the clickbait for good health, in terms of what kind of study are we looking for? Chocolate is good for you.
Chocolate is bad for you. [Laughter] Alcohol is good for you. Alcohol is bad for you. People want permission to do things that they already do or want to do.
And these are usually really common behaviors like red wine, coffee, or chocolate. Everyone has an opinion about that, right? How do you take your coffee?
Where do you buy your coffee? Um, and it's usually a very simple thing that's associated with high-risk, very high-risk outcomes like dementia.
So, it's a matter of seeing and being skeptical if you see any research studies that support these factors. Now, what should you do to prevent dementia?
Exercise, improve your diet, focus on weight loss, the things that we don't like to do, the things that you know.
that you do that are boring. That needs to be addressed. Ah, the damage is done. Doctor. Thank you, Dr. Langer.
New study shows how coffee can lower the risk of dementia
New study shows how coffee can reduce dementia risk. New research suggests that a staple of the morning for many of us may reduce the risk of dementia.
A major study has found that moderate coffee or tea drinkers may have some health benefits. Karen Howie has the details.
It’s delicious. Houston. Always black, no cream, no sugar. That’s how he always starts his day. I try to drink just two cups of coffee. A new study in the journal JAMA looked at the data.
More than 130,000 adults were followed over four decades to see if coffee and tea consumption were associated with dementia risk. Caffeinated coffee or tea, so 2 to 3 cups of coffee a day,
1 to 2 cups of tea per day were associated with a lower risk of dementia. But we can’t say based on this study that it’s actually protective. Dr. Celine Gonder is a medical assistant at CBS News.
Study found no link with decaffeinated coffee, study says. Possible benefits.
Now experts caution that this study shows an association, not proof that drinking coffee or tea protects against dementia. I would caution against changing your habits around caffeinated beverages based on this study alone.
They found a possible protective effect only with very moderate consumption. It's not something you're already doing. I'm not suggesting you start drinking anything.
Who is at high risk of heart disease? Who has high blood pressure? Who is at risk of heart disease? Coffee may not be the best thing for you. The researchers say
that while the results are encouraging, the effect size is small, and that exercise, eating right, and getting enough sleep are important ways to protect cognitive function as people get older.
Drinking 2-3 Cups of Coffee a Day Tied to Lower Dementia Risk
Drinking 2-3 cups of coffee a day is linked to a lower risk of dementia, and for millions of people, the steam rising from a cup of coffee or tea is a daily comfort.
But new data suggests it’s also a powerful shield for the brain. More in the next report. Watch, the steam rises, the aroma
lingers.
For billions, tea or coffee is a comfort, a habit, a routine. But there may be something else quietly powerful beneath the ritual of [music]. At first, it seemed like a coincidence.
Then the data gets deeper. According to a report published in the Journal of the American Medical Association [music],
People who drink tea or coffee twice a day have a lower risk of dementia. To reach this conclusion, researchers studied the health records of more than 130,000 people over 40 years. According to the study, caffeinated
Coffee drinkers also reported slightly less cognitive decline than those who opted for decaf and performed better on some objective tests of brain function.
Tea and coffee are packed with bioactive compounds. Caffeine boosts alertness. Antioxidants fight inflammation. Polyphenols may protect brain cells from damage.
Together, they appear to support neural networks involved in memory, learning, and attention. Researchers observed that two to three cups a day showed the strongest link to reducing dementia risk.
More is not necessarily better. Experts caution that [music] is a balancing act. Too much caffeine can disrupt sleep, a key factor in mental health.
Instead, they point to lifestyle. Dementia is shaped by many forces. Genetics, [music] exercise, diet, education, sleep, and social connections. Tea and coffee seem to fit into [music] the big picture, small, stable protectors.
For now, the message is one of reassurance, not revolution. Your daily cup is not just fuel. It can be a calming treat for the mind. In the world of complex solutions that chase after, it may already be sitting on the kitchen counter, warm, familiar, and gently protective.
