Is Coffee Bad For My Blood Pressure And Heart?

One of the most frequently asked questions about blood pressure

I hear people say that coffee is no good for my blood pressure and my heart. Is it all bad?

No, it’s not all bad. We often focus on the fact that coffee contains caffeine, a bitter-tasting white crystalline substance that scientists describe as the most commonly consumed psychoactive drug in the world.

Caffeine’s ability to stimulate our brain and thus our central nervous system means that, in excess, it can leave us feeling jittery and makes it hard to relax and sleep well.

Four to six caffeinated drinks a day is generally regarded as a “moderate” and safe consumption, although pregnant women should stick with 200mg of caffeine (about two cups of coffee a day).

As far as blood pressure is concerned, caffeine does lead to increases in people who don’t have it regularly, but tolerance develops within several days and research suggests that when consumed in coffee (as opposed to caffeine tablets), its impact on raising blood pressure is comparable to the effect of walking up stairs.

Evidence that coffee causes the heart to race after drinking is, experts say, “anecdotal and tenuous”. As for heart disease, if you avoid coffee that hasn’t been filtered or boiled then it does not increase “bad” cholesterol.

It is increasingly recognised that coffee is more than just a sum of its caffeine, milk and sugar load, providing us with hundreds of compounds including a host of antioxidants such as cholorgenic acid and lignans.

Research suggests that having between one and three cups of coffee daily may help to reduce the risk of heart attacks, and that this may in some part be down to these supernutrients.

A new analysis of 42,000 people in Europe showed that people drinking four or more cups of coffee daily were less likely to develop type 2 diabetes compared with those sticking with just one. The apparent protective effects may again be down to cholorogenic acid, which in experiments seems to help to inhibit glucose absorption and even out insulin levels. The mineral magnesium, found in coffee, may also play a protective role.These potentially protective effects appear to have nothing to do with the caffeine in coffee because decaf drinkers in the study had an even lower risk of type 2 diabetes.

As scientists from Harvard University inform us, human and animal studies suggest a hint of protection against Alzheimer’s. Early evidence suggests that coffee may fight against beta-amyloid plaques in the brain that could cause Alzheimer’s.

Alcohol Caffine Drinks – Health Warnings

Jenson Button crawled in fifth place at the Brazilian Grand prix to take the Formula 1 World Title for 2009.  The only remaining race in the F1 season is  the Abu Dhabi Grand Prix – then the rounds of who sponsors who will begin once again.

New to sports sponsorship are the latest group of drinks companies who are lobbying for acceptance with their latest blends of alcohol and caffine stimulation drinks – one up on poor relation taurine based Red Bull these turbo pops are fast growing in popularity.

So how is this different than a rum and coke? Irish cofee? etc. Drinkers have been mixing alcohol with caffiene forever. Now it’s wrong because the industry is doing it for us?

The drinks, which are sold under names such as Joose, Four Loko and Liquid Charge, typically combine malt liquor, vodka or another alcoholic beverage with caffeine or other stimulants.

In the US health-advocacy groups are urging government to closely regulate caffeinated alcoholic drinks, a small but fast-growing category popular among younger drinkers.

Proponents of tougher regulation are calling for everything from outright bans to warning labels stating that mixing caffeine and alcohol could carry health or safety risks.

A primary concern of the groups is that caffeine and other stimulants may mask feelings of drunkenness, which could lead users to act recklessly, such as driving while intoxicated.

Some thoughts about the health effect of these drinks

An excellent example of how researchers can twist around correlation to show whatever causation they set out to prove. I would suggest that the type of people who drink red bull and vodka, instead of something a little less party-ish, are the type of people who are more likely to do stupid things in general, and probably are out to get smashed regardless of how much caffeine the government does or doesn’t allow them to mix with their liquor. You may as well come out with a study that shows people who drink jack daniels are more likely to gt in bar fights than people who drink johnny walker – that must mean that common whiskey gets you drunker than a good scotch, right?

Even if we did put labels on these drinks, there’s still millions of helpless consumers out there mixing jack and coke. Surely a major public health campaign would have to happen. How about: if some actual hard science comes out about this, we just wait and see if it gets around without the government having to do anything, much like the common knowledge that alcohol makes you drunk?

The long half-life of caffeine makes it a less than genius decision to consume at 9 pm (which only increases alcohol’s effect on sleep quality), the notion that it can sober you up is less than genius, and the the plan to be awake enough to get drunk and be an idiot all night is also, yep, less than genius. But an idiot with a pencil can cause harm to himself and others if motivated/bored enough, not a reason to get rid of pencils. Caffeine can increase respitory rate as well, allowing me to smoke more cigarettes on the patio Saturday morning, shall we have an article on that?

Sounds like these drinks are pretty much the same as a rum and Coke.

A better use of regulatory oversight would be in monitoring products like Red Bull that are marketed to kids. High school students with a backpacks full of sugar-caffine charged beverages seems to me to be the greater health risk.
