Apparently a friend of mine was raised by vegetarians and hence was never given meat while growing up. She says that now, when she eats meat in appreciable quantities it causes her stomach to get upset and possibly even leads to vomitage.
Is there any particular remedy for this? She’d be happy enough to become a carnivore if it wasn’t for this issue.
I don’t really know the biology of it, but your body adjusts when you go from a diet that includes meat to one that doesn’t, or vice versa. If your friend wants to start including meat in her diet she can, but she should start out with fairly low quantities and work her way up so that her body will more gently adjust to the change. Fish and lean meats will be easier for her at first. Fattier meats will make her more nauseous until her body gets used to them.
It is dangerous to eat a lot of fat until the gall bladder ramps back up by slowly introducing fat to the diet.
This is pretty common with people who go on very fat-restricted diets for long periods of time. (and so is gall bladder removal when they ignore the above advice and binge after a long diet).
Mr spurlock suffered from this in “Supersize Me”. The fact that his doctor didn’t warn him about it says something about the quality of his doctor. The fact that he didn’t mention it in his film says something about his integrity as a documentarian.
You’re assuming she’s eating a low-fat diet. I’m a vegetarian and my diet isn’t low fat much of the time, yet I still get nauseated eating meat. (No, I’m not being all fluffy-bunnies, poor-widdle-critters about it.)
She should start very gradually. Light fish with little fat or cholesterol, even starting at tiny slivers of flesh at first, and work her way up.
Neither Spurlock’s remark about his wife’s cooking nor the statements in the OP say anything about the eater in question having been on a low-fat diet before starting their new dietary practices.
Yes, vegetarian diets in general are somewhat more low-fat than ones that include meat, but as Ferret Herder notes, not all vegetarians eat very little fat. For all we know, both the OP’s friend and Spurlock could have been constantly chowing down on cheese and eggs and avocados and nuts and other fatty foods in their vegetarian days.
Maybe the problem is that would-be carnivores eat some meat, have trouble digesting it and feel unwell, and consequently avoid meat for a while, thus never getting their digestive enzymes boosted back up to normal carnivore levels.
So maybe the solution is to start off eating very small amounts of meat every day, and then gradually increase the amount while decreasing the frequency.
