  • Too much protein - bad?

    Is there any science behind the idea of too much protein (meat especially) being bad for us.

    I'm seeing reports here that higher meat consumption is linked to cancer, especially colon cancer. (Though I tend to think cancer is linked to sugar consumption.)

    Still, I guess meat is contaminated with all growth hormones and antibiotics and crap they feed the animals? COULD this cause can

    I'm not buying it hook line and sinker, but just wondered why these ideas persist, and if there's any science behind the claims at all?

      A buddy of mine (who is otherwise rather intellectual) quotes that idea pretty often. He had a Navy mate of his die from colon cancer in his 20's, and subsequently was a seafood-only person in his meat consumption. He doesn't do that anymore, though he keeps his meat consumption in check.

      He also cites some Scottish study about the areas of highest meat consumption also having the highest heart disease rate, but his details are scarce and I haven't looked into it.

        search the wilds of the internet and you can find studies supporting any argument you can conjure.

        we evolved eating an omnivorous diet, but whoppers and pepperoni stuffed hot pockets shouldn't be part of what we eat now.

        consuming well-raised meat and wild seafood has improved my health so dramatically over a grain-based diet there is no doubt in my mind it's better for me.

        some studies suggest that eating over 50% of your cals as protein may cause some issues, but that's pretty hard to do.

          Robb Wolf talked about this in one of his podcasts. The researchers in these studies were very lenient with their definition of a portion of meat - under their rules, a slice of pepperoni pizza and a chicken breast were equivalent.

          No wonder they "discovered" that meat causes cancer. Just ludicrous.

              i believe many of the men in that recent study also drank more than moderately and smoked. soooooooooooooo, yeah.

                Some of the many confounding factors- people who eat less meat usually do so because they are conscious about their health, which means they are more likely to exercise appropriately and less likely to drink in excess or smoke. There are way too many confounding factors in observational studies about food. Some studies can influence public perception of a food, leading to shifts in the populations that eat that food, influencing other studies that are going on.

                Eat food.

                  Any basic health studies will try and account for variables like smoking and alcohol consumption.

                    Oh, they will try.

                      There's also the factor of placebo compliance, where they give people a placebo, and but not everyone is consistent about actually taking their medicine. it turns out that the diligent placebo takers, have better health outcomes than the people who didn't diligently take their placebos consistently.

                      I think that's the same thing as here. Everyone 'knows' what to do to be healthy, so the people who are diligent compliers do those things, and have good health outcomes. Because of some innate characteristic of them, not necessarily because what they did gave them the better outcome.

                        Too much protein shouldn't be bad. It gives you energy and promotes cell growth. The only thing you should be worried about is having too little protein, which can lead to feeling weak, light-headed, and hungry. It happened to my dad when he first started his diet. I had to help him include more protein in what he ate.

                          Actually, too much protein is bad.

                          Your body i smarvellous in that it can convert food between protein, fat and carobhydrates if you don't eat it in the exact proportions of what it needs. Fat and carbohydrates are both composed of carbon, oxygen and hydrogen atoms. While protein also has Nitrogen. So eating too much protein means that when your body builds the fat/carbs that it needs from your surplus protein you have extra nitrogen left over.

                            Too much protein can lead to gout.

                              Too much of anything becomes a problem when regulation is broken and unmanageable. Too much protein with leads to improper breakdown, processing and removal can cause chaos to a number of organ systems.

                              I am not saying that everyone who eats a ton of protein will run into crazed out organs....what I am saying is that overloading can overwork the system. Parts of the system will malfunction and ultimately fail if not addressed.

                              The best strategy is to find way to support the parts and the overall system if one is overloading. (One also must determine what level is considered overloading for that individual).

                              Protein and Cancer share signaling pathways (mTor pathway) which means that both can activate or involved heavily in cell size. If you think about how Cancer cells divide and grow and repeat this process with out dying off, you can really see how protein can play a role on the consistent and continual "building block" of cells.
