As reported yesterday, the gelatin i've been supplementing for the last five months definitely has an effect, but it's not all that easy to tease out the specifics. There has been no other change in my diet or supplement regimen to explain the reduction of grey in my hair, and from the very beginning i've seen less "protein desire" in my food intake as a whole. But gut-health...? I THINK it's better.
In the fall i ran out of the bottle of betaine-HCl i had around, and i delayed getting another because i was using it so seldom. Thanksgiving day, we whooped it up with champagne* and i got that old familiar too-low-stomach-acid feeling, but trying to improve it with vinegar just didn't do the job. I seem to have kindled an H.pylori flare which answered to epizote, but which hasn't completely gone away. My stomach has required extra care since then, but my intestines have been quite happy...
...EXCEPT when i eat a heavy load of vegetables. VEGETABLES (and that's a colon issue). Throughout the winter, i've had some wheat-cheats every couple of weeks that haven't distressed me. I had a bean-cheat last week (CHILI -- ahhhh!) which was not a problem, cuz i soaked the beans over 24 hours till they went bubbly, rinsed well, cooked, rinsed again, and diluted with a LOT of ground beef. :-D
I credit an extended period of grain-avoidance for having healed my gut, long before i started the gelatin experiment. When we visit a fine restaurant these days, i occasionally (NOT regularly) indulge in a gluten-containing specialty, but usually it has to be DAMNED special to tempt me. On those rare occasions when i do, i get very little repercussion -- my bad knee is still a bit bad, but my good knee is better. THAT is the coalmine's canary. I know my gut is better, but has the gelatin helped? Can't tell.
Other joints seem happier -- nice and flexible. Pain-free, except the right knee, and it was actually injured a few years ago. I don't notice any significant changes in my skin or nails -- those were always pretty strong. It only JUST occurred to me to look at the ends of my hair -- i haven't cut it in a year, but i don't see the kind of split ends i used to see back in my low-fat days. The pull-to-break test shows the proper effect.
Is gelatin beneficial and worth taking daily? YES, i firmly believe it. I think we have a special need for the amino acids in broth, beyond what we get from eating muscle-meat. Would broth be better than the powdered gelatin i use? Probably, but that requires more work, planning and discipline. Putting the Great Lakes product in my first morning cuppa is EASY.
Perhaps when i run out of the hydrolyzed collagen i'll look into the cartilage supplement on which were based so many of the positive studies described in "Nourishing Broth." HC itself underwhelmed me, but it was a little easier to use -- you don't have to dissolve it in cold water before adding to a hot liquid, and it can also be utilized cold. If i were to start the experiment again from the beginning, i might start with the HC rather than the G, to eliminate the confounder. As it is, i'm happy with gelatin.
* what is it with champagne??? it's worse for my histamine issues, too, than other wines are....
