I HIGHLY encourage you to read this article which talks about the use of antibiotics in our culture over the last 50+ years. First to treat infections, but then to encourage growth in farm animals.
As a vegan, healthcare professional, I encourage everyone to quit blaming their providers for “over-prescribing” antibiotics, as most of these prescriptions are cause by the demand. (And I do mean DEMAND.) Unfortunately, this demand has been caused by poor research, and companies attempting to make more profit without doing a thorough check on the side effects of this process.
It’s a great read, as are many of the comments.
