I am not sure what is being debated here. Is it whether or not this mysterious RS is necessary, or whether or not it does anything in particular? I don't eat resistant starch. I just eat food. If it has RS in it, well, who cares? That reminds me. Time to bake my breakfast potato. Why? So I can get my precious RS? Of course not, silly. I'm having a potato because it's big and I'm hungry and it'll go well with my salmon.
