Caffeine in your bloodstream ain’t all you might worry about


Steven Ward, OSU

❝ Scientists at Oregon State University may have proven how much people love coffee, tea, chocolate, soda and energy drinks as they validated their new method for studying how different drugs interact in the body.

In conducting mass spectrometry research, Richard van Breemen and Luying Chen worked with various biomedical suppliers to purchase 18 batches of supposedly pure human blood serum pooled from multiple donors…All 18 batches tested positive for caffeine. Also, in many of the samples the researchers found traces of cough medicine and an anti-anxiety drug. The findings point to the potential for contaminated blood transfusions, and also suggest that blood used in research isn’t necessarily pure.

❝ “From a ‘contamination’ standpoint, caffeine is not a big worry for patients, though it may be a commentary on current society,” said Chen, a Ph.D. student. “But the other drugs being in there could be an issue for patients, as well as posing a problem for those of us doing this type of research because it’s hard to get clean blood samples.”

Article worth reading, folks.

I keep an eye on nutrition and health studies – and being a lifelong coffee drinker that’s one of the substances I track. I even quit drinking coffee for a few years after a scary preliminary study – eventually disproven – from a solid medical source rolled out too many threats to rationalize.
