If there is anecdotal and circumstantial evidence that something is bad for you, and most of the people who avoid that thing are visibly healthier than those who don't, shouldn't you avoid it out of caution? This is also a sensitive topic to research because it impacts an enormous part of the economy if these things are shown to be harmful, and in many cases there are not good substitutes that are safe and economical. Edit: And if you disagree with my first point, are you consistent in your own life, e.g. did you treat coronavirus with the same skepticism? How about mask wearing? There's not much high quality of evidence on masks, or at least there wasn't early on.
