> We're looking at dozens (maybe hundreds) of research papers published over the past 40 years. And how many nutrition researchers and students do you think there are? How many do you think choose to do a study about a popular diet? Do you think everyone who fails to reject the null hypothesis with whatever mediocre p-value criteria their supervising professor decided on publishes their paper anyway? Do you think most journals would accept such a paper? > however, if a study found the diet had any relatively negative health effects That's the thing. Almost any semi-reasonable diet isn't going to kill you or make you horribly sick. Every dietary recommendation you find online will probably keep you alive and healthy. Then, by the nature of having lots of scientific papers and the way publishing works, you can find as many papers as you like claiming that your favorite dietary recommendation is slightly better than the other ones.
