IS THERE ANY MEAT THAT COULD BE HARMFUL TO HEALTH WHEN GOD DECLARE THAT WE SHOULD FEED ON EVERY LIVING THINGS THAT IS MOVABLE?

When God had finished the work of creation he pronounce to man in
Genesis 9:3
"Every moving thing that lives will be food for you. As I gave you the green herb, I have given everything to you."
Why do we then chose what to eat when God commanded us to eat with every moving things?
In some region in Nigeria and Africa as a whole many moving creatures are forbidden substance to be consumed.

In Akwa Ibom Nigeria, we are restricted from eating wildcat and monkeys, I kept asking why we should not eat these things but there’s no specific answer, the only response I had was that anyone from my tribe who attempts eating the above mentioned creatures will distended and become pale whilst waiting for his dying day. Nobody knows if this tenet is faulty nor if they existed in ancient day, all we do is to keep to the regulations because nobody is willing to die.

In the Yoruba region of Nigeria people find it delightful in eating snakes like the python, other regions persecute the creature regarding the curses God placed upon the reptile and also having see this creature as Satan’s tool.
Genesis 3:14 "Yahweh God said to the serpent, “Because you have done this, you are cursed above all livestock, and above every animal of the field. You shall go on your belly and you shall eat dust all the days of your life."

In some part of the country like the Igbos, they treat snakes in A state worthy of esteem and respect, they regard it as their own god and it has been given the dominion to crawl to any part of their city and can go into any house at anytime without harm. There was once a story took over everywhere how a python swallowed a child in that tribe, people were watching and didn't kill the sapient because the rules in that region state that anyone found of killing snakes will bury them like a human being.

When things tends to happen this way I keep wondering, who is right? And who is wrong? Could God be mistaken to have commanded us to eat everything? The people around us who threatens many to stay away from eating most of them for health purposes who are they?

DO THEY KNOW BETTER THAN GOD?
