In what world would 100 people be enough to represent anything accurately enough to make a generalized claim like this? All I know from the article is that there were 50 women and 50 men involved. It says nothing of age, fitness, dietary regimen, etc. Based on the "statistics" provided, I could equally make the claim that "drinking a warm drink reduces DNA damage".
Also, please don't generalize "people" in your backhanded comment. I recommend that you study up on critical reasoning. Maybe then you would come to understanding that most "statistics" are unintentionally (or intentionally) biased, and are therefore bullshit, and not to be taken at face value.
I criticized your backhanded N = 100 comment because it's silly.
Your comment "In what world would 100 people be enough" shows your disbelief in basic statistics.
In typical well conducted study N=100 participants is close to the minimum sample size when the population is large.
No statistician says that N = 100 is not enough to represent things accurately without knowing other parameters and the design of the study. With large enough effect size N=1 is more than enough and. N = 1800 is enough even if the population size is infinite in the optimal case.
