Drinking coffee helps maintain low blood pressure, says study (1 - 3 cups daily)

Drinking coffee helps maintain low blood pressure. People who drink two or three cups of coffee a day have lower blood pressure than those who drink just one cup or none at all. This applies both to peripheral and central aortic pressure, i.e. the one closest to the heart.

The investigation analyzed the association between coffee consumption and peripheral and central blood pressure parameters in a sample of the Italian population.

"The results obtained show that those who regularly drink coffee have significantly lower blood pressure, both on peripheral and central levels, than those who do not drink it," explains Arrigo Cicero.

However, it is not yet clear what these benefits are due to, and they do not appear to be directly related to the effects of caffeine.

"Caffeine is only one of the several coffee components and certainly not the only one with an active role. Positive effects on human health have indeed been recorded even among those who consume decaffeinated coffee," says Cicero. "We know that caffeine can increase blood pressure, but other bioactive components in coffee seem to counterbalance this effect with a positive end result on blood pressure levels."

The scholars looked at a sample of 720 men and 783 women from a sub-cohort of the Brisighella Heart Study.

"The results are very clear: peripheral blood pressure was significantly lower in individuals consuming one to three cups of coffee a day than in non-coffee drinkers," Cicero explains. "We were also able to confirm these effects with regard to the central aortic pressure, the one close to the heart."

Indeed, data show lower values for coffee drinkers in both systolic and pulse pressure, and in both peripheral circulation and central aortic pressure. All results confirm the positive effects of coffee in mitigating the risk of cardiovascular disease.

A study I posted in the last day or two showed 50% of the population had a gene that makes having caffeine equal to three cups of coffee or more a day, more likely to cause kidney problems, so consider keeping your coffee level at 2.75 cups a day.

The current study shows a statistically significant difference in BP according to coffee intake but the magnitude of the difference is only 3-4 BP points.

“People who drink two or three cups of coffee a day have lower blood pressure than those who drink just one cup or none at all.”

What about people who drink 8?

It’s what you do after you drink the coffee that can raise your BP.

[Verginius Rufus]

I’ve wondered if I should avoid drinking my first cup of coffee until after I take my blood pressure. Maybe I should try before and after (first, second and third cups) to see what kind of results I get. Mostly feasible on weekends.

Like turn on the TV and listen to the news?

It would help to know what their definition of a cup of coffee is. I’ve seen three different ones.

[Mark]

Good news.

[airborne]

I have 2 or 3 cups every morning and I have normal to lower than 120/80 average.

[Track9]

I’m sure you’re right. Haven’t ever had one and that’s a big part of why.

[Agatsu77]

Being someone that REALLY appreciates coffee, Woo Hoo!!

Sounds good to me.

[Mean Daddy]

3 cups per day. 110/70 almost every time it’s taken.

[Persevero]

I always get my BP taken BEFORE I have any coffee. Doc says it spikes things. I am almost in my 60s and so grateful I still have normal Bp.

At least before I’ve had coffee…

So I am curious about that. I have a couple cups a day and I assume I spike for a while after each cup. So why the headline if it spikes it?

Ans tomorrow we will see a story that states coffee raises blood pressure.

I wake up & drink a cup of dandelion tea with 1/4 tsp. of Hawthorne Berry powder (good BP lowering effects) then do yoghurt-granola with flax seed THEN I get two cups of strong-AZ coffee.

[joshua c]

my doc told me i could only have 2 cups a day

so i bought a bigger cup

[Verginius Rufus]

Smart move. He didn't say how big a cup.

When Teddy Kennedy was questioned after he drove his car off the bridge at Chappaquiddick and left Mary Jo Kopechne to drown, he claimed he had had only three rum-and-cokes at the party. He should have been asked how big the glasses were and how many shots of rum in each. 32 ounce glasses?

Benefits from drinking coffee might be from the niacin in it, IMHO.

Last week I was in the hospital with Congestive Heart Failure. Never for a single minute felt sick. Hospital served decaf. Right before checking out, the entire med team came to say good-bye. “Any questions? “ the head cardiologist asked.

I told him I make half-caf at home, two cups in the morning and asked if that was OK. “Absolutely. That counts as one cup, perfectly OK.”
