There is no evidence blood pH levels are affected. This is alarmist media. Are we going to ban soda?

    Biochemist here. People on Lemmy should read links they post.

    As with any buffer system, the pH is balanced by the presence of both a weak acid (for example, H2CO3) and its conjugate base (for example, HCO−3) so that any excess acid or base introduced to the system is neutralized.

    A lot of academic labs love to get attention with alarmist claims, and assume the actual data was done properly.

    See DTT, see BPA, bullshit that never dies.

    The literal paper that this post is about says multiple things about this subject. Did you read that paper?

    Thing #1 is that blood ph is decreasing in lockstep with atmospheric CO2.

    Thing #2 is that it appears the body's buffering system is stressed and is pulling additional calcium + phosphorus from the skeleton to aid in buffering.

    So your comment isn't wrong about the basic idea, you just didnt observe what's happening the larger context. PH is not only predicted to drop, we have already seen it drop, it's already started to happen.

    For this alarmist claim to be wrong, are you suggesting they cannot even accurately measure blood ph?

    There absolutely is, and you can do a simple experiment at home with some water, indicator solution (one can be made with red cabbage juice, but we used to use methylene blue when we did it at the science centre) and a soda water maker (or dry ice) to see it happen.

    It's not completely representative, obviously, but blood is mostly water and the same pH change we can see in carbonation water will happen to blood plasma.

    so we should ban carbonated beverages or not?
