Well I hope you do a better job of judging what is being taught by actually reading more than that.
Eating what is ever around is called local in-season eating and you will find much discussion about that on the website.
God did not create the garden of eden to be an idol. God called everything He created good but we are not to worship the created. Once man started falling away from God's wisdom, the balance of the law of nature that God set in place began to change.
Yes, I agree the devil in in the details of diet.
Anyway I thought you would find some interesting things to read on that site but then again maybe not. You may be too busy to read as much as it would take to have an better understanding. Thanks for spending the time to answer. :)
