So many studies say coffee is hurting you or coffee is helping you…

everyone wants something out of coffee, but all it wants to do is give!

Howdy hot brown water hawkers, Trace here for DNews.

Scientists have again, and again, and again tried to find out what coffee is doing to

A study in Scientific Reports lays out nicely, "coffee consumption has been linked to protective

effects on various common pathologies such as cardiovascular diseases, hypertension,

Alzheimer’s and Parkinson’s diseases, type 2 diabetes, some types of cancer, and

hearing functions, and it may predispose to others such as sleep disturbance."

Scientists have been studying coffee since the 1960s, and a 1972 study in Cell's Biophysical

Journal tried to find out exactly what it was doing to our cells, noting caffeine binds

to broken DNA, and that if it's present during the formation of new DNA, it can cause breaks

in chromosomes (which is why we've long known pregnant humans shouldn't consume it).

We've also found that when DNA is broken by other processes, caffeine can play with those

But confusingly, a study in March 2016's Molecular Nutrition & Food Research found coffee drinking

reduced DNA breakage by about a third, and that reduction continued for hours!

So, coffee (or caffeine really) can break DNA, or keep it from being broken, depending

It's important to note, DNA breakage is not necessarily a bad thing; normal cell functions

can break it, but so can UV light, and certain chemicals, and irradiation.

In the decades since we started looking into coffee and caffeine, study after study keeps

For example, a study in the European Journal of Nutrition found spontaneous DNA strand

breaks were somewhat less likely in those who drank dark roast coffee.

A 2012 study in Cell Metabolism found the DNA of people who exercised had fewer methyl

groups -- a specific type of chemical marker that occurs when DNA goes through a chemical

This shows exercise and coffee affect the DNA pretty dynamically!

Another pair of studies, one with Italians (who do love their caffé) and another in

the Netherlands (the Dutch drink 2.6-times more coffee than Americans), found people

who drink coffee pass their habit to their offspring, pinpointing several genes associated

Which is interesting, because a study in Scientific Reports found a mutation on gene PDSS2 which

is associated with drinking fewer cups of coffee.

In a twin study using both identical and fraternal twins, the identicals had higher correlations

of habits like smoking, coffee drinking and alcohol consumption; indicating to the researchers

You can change your DNA with your behaviors in life -- this is called epigenetics.

A study in Biochimie found mice that were chronic over-eaters, passed genetic markers

to their offspring which then had higher levels of insulin resistance… so they were more

In my opinion, a lot of these studies have more to do with our love of coffee than the

magical powers of this beverage we happen to drink.

According to the International Coffee Organization, over nine billion kilograms of coffee were

Most of the countries on our planet consume coffee, it's one of the most consumed beverages

anywhere (tea is the tops, of course), and is one of humanity's primary sources of the

And yet, it's super interesting that we still don't know a lot about the epigenetics of

And remember, it's not just about coffee.

All DNA is constantly affected by the food you eat.

DNA is created, copied and created throughout your life -- so you are literally what you

So next time you're having a java, think about your kids.

More research is needed and science is awesome.

When you don't get your coffee are you a monster?
