This from the BBC:

Drinking decaffeinated coffee could increase the risk of heart disease, a study has suggested.

It could lead to a rise in harmful cholesterol levels, the US National Institutes of Health study found.

[…]

The US study looked at 187 people, a third of whom drank three to six cups of caffeinated coffee a day, while a second group drank the same amount of decaffeinated coffee, and the rest had no coffee.

Researchers measured the level of caffeine in people’s blood, as well as a number of heart-health indicators, including blood pressure, heart rate and cholesterol levels over the course of the three month study.

At the end of the study, the group drinking decaffeinated coffee had experienced an 18% rise in their fatty acids in the blood, which can drive the production of bad ‘LDL’ cholesterol.

As for me, put in a ground-up NoDoz with each teaspoon of sugar. 🙂
