Yes, I'm aware that studies do not converse with people. When someone says a study "suggests" something, I understand them to mean that it gives very tentative evidence. Such evidence is frequently contradicted by other studies: see https://www.sciencealert.com/images/art-apr-15/Medical_studies-05.0.png https://www.sciencealert.com/images/art-apr-15/Medical_studi..., which another commenter has linked. If one study suggests that eggplants may prevent heart disease, you can pretty much bet that another will suggest it causes it. That's why I'm saying to ignore this. We would all do well to eat better and exercise more, suggestions that are well-supported by many studies. If we're not doing that, we're certainly wasting our time on uncertainties like this.
