Just out of interest (I don't think I could bring myself to eat meat), have you started to eat meat again and noticed an improvement in your IBD?
I just started today!! with oysters, but i will be eating 3ozs of beef per day I think, now that i just learned some oysters have lead in them. But i suspect i will have higher zinc levels because of going back to meat, and zinc is supposedly an anti-inflammatory, thats one reason it could help my crohn's as i believe I'm too low in minerals. my iron levels are about half way which is acceptable when i had a blood test though, its probably because i take 500mg vitamin c which helps absorb iron better from plant foods, I don't take an iron supp by the way.
There is so much bad press on red meat though, it's just controversial but i believe its what makes us human, even though some of these farmed animals may not be the healthiest compared to how they live in the wild. Now that I've read some scientific articles on zinc deficiency and how meat eaters rarely have it, and also how zinc is one of the most abundant minerals in the human brain and also an NMDA antagonist which is one of the most promising targets for treating depression as ketamine has shown rapid recovery of depression within 24-48 hours in studies, its also an nmda antagonist, i just suspect that not eating meat has made my overall health worse over the years. There some research that suggests red meat increase the risk of colon cancer, but then i also just read studies showing colon cancer cells are severely low in zinc, and the increaseing zinc levels stops their growth and is protective, and red meat is the highest and most absorbable source of zinc so its hard to believe red meat could be bad for colon cancer.
Some studies show that iron administered alone can be a potent oxidant under inflammatory conditions, but when you consider iron in red meat is always paired with selenium and zinc, which are potent antioxidants you'll see it seems to balance things out and those lab study scenarios probably can't tell us exactly what is going on in the natural world, unless you decide to take an iron supplement when under chronic inflammation which is probably not the best idea. And there are some scientists who now thing giving other minerals like zinc along with iron to treat anemia, is a good idea.
Then there are studies that claim sialic acid in red meat or meat in general is involved in increasing inflammation, but sialic acid is also in human breast milk and enhances brain growth for infants? so there are lots of studies and papers and I've looked them over and the case isn't very strong for red meat being bad for us, in fact the better studies show that red meat and meat in general is necessary for optimal functioning.
then there is arachidonic acid which could increase inflammation, but it's also a major part of your brains cells!! like dha! It seem scientists like to explore many ideas, and they are communicated in the wrong way, and they are still just trying to evaluate these ideas, but I'm going back to meat and getting my minerals so i no longer have to rely on crappy mineral supplements that seem to be an inferior way of getting them.
