I'll go one stronger and say "You Shouldn't Trust Any One Scientific Study You See".

Individual studies can be really interesting. They're important for researchers to know about to inform their future work. But any one study - even ones that are done honestly, with good methodology and sound foundations - can be just totally wrong. There could be confounding factors you couldn't have known about that completely invalidate the result. Your test subjects could be unusual in some way, your animal models could be a poor analogue for humans in this particular case, you could have just had really aberrant statistical flukes in your statistic sampling.

It's the body of scientific research, the dozens, hundreds, thousands of studies stacked on top of each other that bring certainty.
