  • Is mixing proteins a bad idea, and if so why?

    Personal experience confirms for me that mixing, say, steak and chicken in one meal is not only just plain weird but causes digestive issues and tiredness. The body seems to have a hard time breaking down the food. What's the consensus on this? Is there science behind it? Maybe the different molecular structure of the proteins is "confusing" to the enzymes and harder to break down.

    I ask because I suspect that mixing eggs and bacon might be more difficult for the body to break down than bacon or eggs alone. Robb Wolf says he has bacon for breakfast, often with eggs.

    Final question: is mixing fats similarly problematic? Mixing olive oil with coconut oil, for example.

    What problem? Eggs and bacon go together like pork and beef. Burgers and cheese. Trout with almonds. Turducken.

      I say fry and egg and top that steak. It may make a difference but I think it is over thinking the situation.
      Eating primal is not a diet, it is a way of life.

        I'm gonna go with ....No to both your questions. No problems with mixing proteins or fats.

        Interesting that I just had meatballs (made with pork, beef, beef liver, and eggs) swimming in its own fat with a tall glass of raw milk for lunch

        One thing to understand is that there is very general enzymes that do the jobs first. For instance pepsin cleave all proteins that enter the stomach regardless of what animal it came from......bile is secreted in response of all fats in the small intestine to aid in emulsification.

                I've never seen anything other than recommendations (not scientifically based) to not eat more than one type of protein, and there isn't anything to back up the recommendation other than to have people eat less. Fats actually help to absorb fat-soluable vitamins. What is more important are the types of fats being used than the mixing of fats.

                More of a problem is the mixing of unnatural things in what used to be good foods (like HFCS in just about everything packaged). When you eat whole foods you have to read a lot less labels.

                  You seem to have all the scientific evidence you need if your body does not react well to it.

                    Yeah...if you react poorly to something obviously tweak it a bit to figure out the issue. Academically though, I can't think of any feasible reasons off the top of my head.

                        That makes no sense to me. I don't think the body recognizes "Oh, this is steak and this is chicken". I think it just goes "Sweet. PROTEIN! Om nom nom."

                          I seem to recall Robb Wolf mention on one of his podcasts about cycling proteins weekly, meaning having a week of mostly chicken, then mostly beef, etc. I can't remember the exact reasoning behind this. It may have been for people who had developed sensitivities to certain proteins. Or I might just be making this all up and my memory is terrible :P

                            Likely to be more associated with the fatty acid profiles. Chicken, beef, and pork are all "complete" proteins...meaning they have the whole array of necessary amino acids. There are differences in vitamin content of the organs/meat and in the fatty acid profiles though. So that is the only reason I can think of....

                              Maybe because I can't afford it???

                              How about antipasto? How about pizza with everything? How about chicken cordon bleu? How about Jambalaya?

                              It seems mixing meats is extremely common. Maybe dumbass American cuisine with it's flabby white meat, steamed and tasteless broccoli, and white potato with margarine washed down with Kool-aid and green jello with horseradish and pineapple for dessert is the only thing that has only one type of protein at a time.
