I'm sorry, what? You're joking, right? There's no such thing as a beef, pork, or poultry allergy. There is a shellfish, but that's about it. There's more allergies and negative side effects from eating plants than there are meats. And you're right, eating meats prepared a certain way is definitely bad for us, but not because of our livers, it's because of our hearts, and it's definitely not enough tk decrease life expectancy unless we're factoring in obesityI. Specifically, eating a burger high in saturated fat (85/15 and anything else) will cause colesteral to build up in our arteries, which, if eaten too much, can lead to Health complications, but eating a burger one meal out of the week will have little to no side effects whatsoever, minus a sated appetite. What exactly does a plant based diet bring to the table? Unless you're eating soy, nuts or seeds, no protein, which your body needs, and the only viable option here is soy, which, as a daily consumable, is actually bad for you. It brings vitamins and minerals that meat doesn't have, so a point for you, but it's not a sustainable diet without protein, yet again. Have anymore invalid points?
