  • Acidic Foods (and Onions) and B-12

    I know our stomach acid has a ph of around 3 but adding a significant amount of more acid could be bad. What effect is possible from adding a serving of onion and other acidic foods? What is the ph of cooked onion and why is it that what I have been reading says onion is a great alkaline food but it is acidic? And also, that cooking food makes it acidic? I know making it alkaline has something to do with some reaction with our body but as a reaction directly to B-12, it could be bad.

    I have heard information about how there is a concern that a significant acidic or base environment can destroy B-12 and that there was all this concern that Vitamin C supplements were destroying B-12 because they contained ascorbic acid. All of the studies I have read so far tested only 2 grams at the most and said there was no effect but what would the effect of adding a quarter cup or more of onion to your dish or soup be? Anyone who has any advice or who has tried to help would be greatly appreciated.

    The help you need lies in scientific literature, not here. But to sum it up, worrying about acidifying foods is pointless when you eat a real diet rich in green vegetables and natural meats, bone stock and liver, etc. These foods contain the basic building blocks for maintaining a proper pH in the body, and for building bone. People eating paleo/primal add bone mass to their bodies (and maintain all those other essential functions!). I mean, if you drank two gallons of green tea every day, you'd be in trouble! But the foods, break even and then some without trying. You know how much B12 we eat? OMG, you'd piss yourself. Add a little vitamin D and there's no stopping us!

      I definitely understand what you are saying Knifegill but from what I could afford I can only eat two servings of beef , 4 ounces lol, and a serving of chicken since I buy organic beef. And I would buy turkey but that is more expensive. One serving of beef has 35 percent the daily value. Chicken has 8 percent lol. So with optimal conditions, I get around seventy percent a day and many people are also in a similar situation as mine financially. But if I could eat the right foods, I wouldn't worry about one of my meals being interfered with onions. I add onions and garlic to a soup I make with beef and it tastes so great. But I am stopping it today and starting with adding it only to my chard soup lol.

        Some foods are acidic in themselves but in your body they have a net alkaline effect. Almost all fruits and vegetables are alkalizing, even citrus fruits like lemon. I'm interested in why this is but I can't really find any explanation, which I guess means I probably shouldn't believe it. But I don't worry about it anyway.

          Check out your local grass-fed butcher. Liver, bones and other organs are typically cheap or free.

            There is many reasons I am sure why there might not be many studies done on certain things in food, because it could have a bad effect on our economy. And that is the way things work. But because there is no study done on it doesn't mean it isn't true. But of course it could be false.

                I used to worry a lot about PH balance because I tend to eat very low carb with not many green vegetables (I love them, but I can't tolerate many carbs).

                In any case, I'd also read that it really doesn't matter in terms of food intake, that the body balances it's PH if you're otherwise healthy.

                Twice within the past year, my primary doctor has run tests that include PH. Both times, I was eating a high-acid, very low carb diet. And both times, my PH came back as perfectly balanced.

                So I don't worry about this any more.

                  Oh emmie I am not concerned about my body's ph; I am concerned that certain acids and bases are destroying B-12 in the same meal. I know what you are saying though.

                    Oh, bah. Good luck destroying all the B12 you'll be taking in.

                      Foods are classified as acid-forming or alkalizing depending on the effect they have on the body. An acid-forming food contributes hydrogen ions to the body, making it more acidic. An alkalizing food removes hydrogen ions from the body, making it more alkaline. It is important to note that this classification is based on the effect foods have on the body after digestion, not on their own intrinsic acidity or alkalinity (or how they taste to us). A common misconception is that if a food tastes acidic, it has an acid-forming effect on the body. This is not necessarily true. Very often, an acidic-tasting food is alkalizing. Citric fruits are a good example. People say that lemons, for example, are "too acidic"; however, they are actually alkalizing because the minerals they leave behind after digestion help remove hydrogen ions, decreasing the acidity of the body. (Many people use the term "residue" or "ash" to explain the effect of a food on the body. A food with an acid ash after digestion contributes hydrogen ions, making the body more acidic; a food with an alkaline ash after digestion removes hydrogen ions, making the body more alkaline.)
                      Another misconception is that acid-forming foods are "bad." This is not correct; acidity and alkalinity are opposites and one is not intrinsically better than the other. This misconception has developed because the North American diet is excessively acidic, which does result in health problems."

                        If anything this thread has made me feel better about what I eat. Looking at that chart, my previous diet was probably 80% acidifying foods. Now its more 50/50. That is amazing!

                          Cordain discussed this topic in great depth. I honestly do not think Grok ran around with pH test strips but since I have a pool and do care about the alkalinity therein, I can point you to some good cheap test kit sources. Seriously, though. Eat good food, not too much, and enjoy it.

                            Thank you all for your help: I wasn't making a claim just posing a question. And Snauzoo, I wasn't looking for the effect of acidic foods or whatever on my body but if it could destroy B-12 if it was in the same meal. But even though Grok didn't walk around with measuring strips, lol I know what you mean, he certainly was more in touch with instinct and knew how good foods were for him and probably avoided many acidic foods from instinct or out of fear. Foods with other qualities as well. But I haven't read too much about the acidic diet and I haven't used it to model my diet.
