Good that we are in the same boat and maybe by exchanging thoughts we might fix it. This i what I found out about this topic:
a) We need to look at the digestion of the stomach. HCI is just a part of it. The whole system is called gastric acid or stomach acid. Therefore just going for HCI might not solve the problem. Gastric acid consists of hydrochloric acid (HCI), potassium chloride (KCI) and sodium chloride (NaCI).
- hydrochloric acid (a strong mineral acid), Foods that mimic and can "replace" HCI in my experience and own experiments are raw corn on the cob (worked great but is expensive in the long run), raw apple cider vinegar (I mix a small cup of water with 5 tbl of ACV and have it sometimes before, but most importantly with and sparingly after food), red wine vinegar (works similar as ACV in same dosage) and raw orange juice (even pasteurized). Then I tried beetroot juice (didnt work at all unless I added ginger), HCI from Thorne Research - Betaine HCL & Pepsin (caused constipation- its produced from pork maybe that´s why or the vegetable cellulose in the capsule was the issue) and Premier Research Labs Premier HCI (caused constipation too, its from a vegetable source- think beetroot but I´m not 100 percent, however easy to find out).
- potassium chloride (somewhat a salt as well). Didn´t do much research about that and I don´t think its the same as "normal" potassium.
- sodium chloride (salt, so there is a reason why some people suggest to eat salt with food so the stomach acids work better)
b) Red wine. I noticed that red wine from syrah (shiraz) and cabernet grapes work great for the digestion of any foods including meats, raw or cooked. In fact when I ate too much and things are stuck in the intestines (such as constipation), or my stomach digests way too slow, then this is what always helps. A glass or 2 will do the trick. Important to stick to acidic red grape varieties such as syrah and carbernet, not grape varieties such as merlot. Syrah worked best for me. That got me interested, so I looked at the composition of acids in wine and you find this:
1. Tartaric acid (found in grapes itself)
2. Malic acid (is in foods such as apple, especially green)
3. Citric acid (found in citrus fruits)
Since I didn´t want to drink that often I tried eating red wine grapes (the commercial ones not the proper red wine grapes), and I had non alcoholic red wine. Proved ineffective. Only real red wine helps. And the alcohol content in it too. It makes the stomach environment more acidic, so food digests better because of that too.
c) That whole wine subject lead me to do a cold pressed “gingershot” consisting (one portion) of 1 green apple (malic acid), half a peeled lemon (citric acid) and approx. a thumbsize of ginger (organic and unpeeled). That works wonders to aid and possibly “mimic” the stomach acids before and after food, or if some food is stuck in the intestines and doesn´t move. I always do a liter ahead, fridge it and have shot glass first thing in the morning. It could be that by adding a juiced grape and possibly salt it would be the best natural increasement of stomach acids, but I didn´t try that yet.
Other things that I noticed:
- What I found works good too and people recommended it is to drink 2 big glasses of still water before a meal, that prepares and increase the stomach acids better and that seems to work.
- I would refrain of drinking still water with foods, that will dilute the stomach acids, however sparkling water seems to aid digestion. I also wait like 30 min to 1 hour before I touch any still water after food.
- Freshly pressed (or worst but still effective - pasteurized) orange juice but NOT concentrate being drunk with food seems to mimic stomach acid pretty well too. When u drink it with a protein meal it digests better for me. I´d say a big glass does the job.
- Raw homemade kefir seems to aid or increase stomach acid too, since homemade kefir is carbonated. However only half of a small cup. Too much and it will need too much of digestion which can backfire.
It´s also very important to look at the causes of low stomach acid. They can be caused by stress, lack of sleep, alcohol and gluten plus overuse of grains (among others). I think the first look one should have when dealing with low stomach acid or HCI, is at the thyroid, since the thyroid apparently regulated stomach acid or HCI. So if u got a underworking thyroid (Hypothyroidism), u first need to fix that before trying to find something that mimics ur stomach acid. Otherwise it will be a never ending story.
I would be careful with cortisol, as far as I know it’s a stress hormone, so the more stress u have, the lesser ur thyroid might function and the lower HCI or stomach acids you might produce. But then again I might be totally wrong since I didn’t see the study.
What I am doing atm is this:
1. I switched from raw paleo to paleo, because like that I can digest food easier. Note that I only steam white meats, I don´t fry or deep fry them, not even in oven. White meats that seem to be easy to digest are chicken and white fish. So Salmon or Beef is out. Game I didn´t try, still need to experiment. I am aware that cooked food even on low steaming temps is not good, but I rather have my meat cooked and digested than raw and undigested. My acid is so low that I can´t even eat raw salads, I need to boil or steam everything to super soft otherwise I can´t digest it. Then once the HCI comes back (to try that I´d do the morning sodium bicarbonate test) i´d switch again to more raw foods including meats. I still have raw foods like raw juices and raw dairy including raw eggs, that seems to be ok.
2. Since low stomach acid or HCI can cause food allergies, hence auto immune issues (I got intolerant to many foods since I couldn’t digest the particles which went unbroken into the bloodstream which created sensitivies) I decided to do the AIP diet first, and voila no more bloating or pain. So the first step is to cut out all foods that cause issues and the same time increase stomach acid. Then gradually implement raw foods again.
3. When I have a big protein meal I take a piece of unpeeled ginger and bite in it once. I don´t chew it, just bite in it and let the juices go down my throat. That helps tremendously for digestion. Ginger in general is great for digestion
4. After eating I walk around 100 steps. That is recommended in Ayurveda as well “to get the food into the right places”. Then I would recommend to rest, so the body focuses the energy on digestion (and possibly secretion of HCI?), not on something else. Ideally you go into the sun and sit down, that speeds up digestion too I found. It could be due to the vitamin d of the sun exposure. Adding a non synthetic vitamin supplement d3 could possibly aid digestion, didn´t experiment in that yet. Or a natural food containing a lot of vitamin d, but it should be easy to digest. Again, I found raw milk a great aid here. Maybe due to the Vitamin D content? I dunno.
