Seeking Insight on Prohibitions in Our Faith

Assalamu alaikum. This might be a common discussion, but it's been on my mind lately. My cousin, who lives abroad, mentioned that in some places, people consume certain foods and seem to live long, healthy lives, while we avoid them yet face health challenges. She suggested historical reasons, like preservation issues in hot climates, might have influenced certain dietary rules. For us, Allah's command is sufficient, Alhamdulillah, but I found myself struggling to explain further. Does anyone have insights or knowledge on why certain foods are considered impermissible, beyond what we already trust in divine wisdom?
