Maybe let’s go to basics – Hashem created the World and gave us Torah. It is accepted that there are two ways to appreciate Hashem – thru learning the secrets of the World and learning Torah. Some, not all, discussions of “Maase Bereshis” and related subjects seem to even include science secrets into Torah secrets.
And seemingly accepted answer is that while it is respectable for humanity to learn appreciate the World; for Jews, learning Torah has a direct access to Hashem’s knowledge, superior to the science approach. Not fully dismissing it though. That is why R Twersky recommends learning physiology to appreciate complexity and beauty of Creation – but not as a yeshiva seder, by yourself at night (this is probably what Rema means).
Now, a hard question – science (including social) has greatly improved from the time of Gemora and Rishonim, and not just summary of achievements but methodology. Say, Gemora in Ketubos 60 discusses how food affects baby development. We now can do medical experiments, statistical observations, double-blinded experiments to study such problems. Were Abaye and Rava to live in our times – would you think they’ll take new knowledge into account? I don’t know whether they’ll go enroll in a nutrition degree, or talk to a nutritionist, or read papers, or conduct their own experiments, but I can’t imagine them not taking this knowledge into account. So, why we do not have modern Abayes and Ravas writing recommendations to chatanim and kallot on what to eat?
