Lowering Dietary Antibiotic Intake


“LOWERING DIETARY ANTIBIOTIC INTAKE” Persistent organic pollutants, like dioxins,
PCBs, can persist for years in our bodies, but other dietary contaminants, like antibiotic
residues and some of the plastic compounds, may be more of a matter of
constantly re-exposing ourselves on a day-to-day basis,
as suggested by this study recently that measured changes in the levels
of antibiotic and phthalate metabolites, before and after a five-day,
meat-free stay at a Buddhist temple. They tested participants’ urine for
the presence of a number of important antibiotics, such as Bactrim, Enrofloxacin, Cipro – and although none of the participants
were actually on antibiotics, the drugs were all found
flowing through their bodies. But within five days eating vegetarian, the study demonstrated clearly
that even short term dietary changes could reduce the frequency of detection
in levels of major antibiotics. Antibiotics detected in
the urine were assumed to mostly originate from dietary intake
since participants with recent medication histories
were excluded from the study. But, see, they didn’t know if maybe the drugs were in
the water supply rather than the meat supply. But, since they were all drinking
the same amount of water the study suggests that the contribution
of drinking water may be negligible in the daily amount of antibiotics
that are inadvertently consumed. To make sure though they
did a follow-up study in which they actually tested
for levels of antibiotic residues in meat, and indeed found that
consumption levels of beef, pork, chicken,
and dairy could explain the daily excretion amount
of several antibiotics in urine and the phthalate contaminates as well. Measures of oxidative stress dropped
as well after the meat-free five-days, but then again they were in a
Buddhist temple meditating all day, so it’s hard to tease out which did what. But the researchers concluded
the results of this study suggest that dietary change,
even in the short term, could significantly reduce dietary exposure
to antibiotics and phthalates, and in turn, oxidative stress levels
in the general adult population.
