I personally thing vegetables are overrated from a health perspective. My problem has been eating too many vegetables with my daily BAS. I have been reducing my vegetable intake and my gut is very pleased with this change. I think it would depend what you're displacing with the vegetables. Are you removing nuts and cured meats in lieu of more vegetables? In that case, I can see it making a big difference. Also, if you are coming from a diet consisting of very little vegetables, no organ meats and lots of muscle meat, I can see vegetables helping a lot since there are vitamins and minerals in vegetables that muscle meats do not contain.
