Oxalate content - grains, legumes, nuts and seeds

@lil-chick exactly something like that.. Anyway like I said before. I think that a lot of people. Especially people who are trying to "eat healthy" like all of us here. Have issues also with oxalates not just vit A and when people talk about detox symptoms from eating low vit A diet. It is also due to detoxing oxalates... I Really think that vit A and oxalates are the main things we should limit as much as possible while eating whole food healthy diets... Foods like spinach and sweet potatoes are crazy combination of high oxalate and high vit A..
Strange study...
Calcium oxalate crystals in the thyroid. Their identification, prevalence, origin, and possible significance
Abstract
Calcium oxalate crystals are not encountered in normal animal tissues, except for the human thyroid, where they were found in 79 of 100 routine consecutive autopsies. They appear during childhood, and numbers of crystals increase with age. In diffuse hyperplasia, prevalence was higher, but crystals were fewer than expected. In adenomas and carcinomas, crystals were decreased except for three cases with a striking focal increase. None was found in 22 adult primate thyroids. After Clorox digestion of human thyroids, calcium oxalate dihydrate was identified by x-ray diffraction and infrared spectroscopy. Origin, tissue and species localization are discussed in relation to ascorbate metabolism, thyroperoxidase, and calcitonin. Possible metabolic roles are suggested. Calcium oxalate crystals injected in animals and humans initiate a foreign body reaction with giant cells. In Hashimoto's thyroiditis, crystals disappear but occasionally remain with giant cell reaction. In subacute thyroiditis, granulomas are related more to colloid than to crystals.
@tim-2 Interesting. I also started taking some malic acid. It can help dissolve anything calcified in the body. Like gallstones, kidney stones + it is involved in ATP production and I believe that malic acid is the reason why "eat one apple a day and keep the doctor away.." 😀
Half of the oxalate our body has to metabolize each day is endogenously created, quite a similar situation to methanol. There are a lot of tasty foods that are high in oxalate so I don't really want to believe we have to limit them a lot LOL. I think Hypervitaminosis A (and probably hypothyroidism) will likely exacerbate oxalate issues. Hypervitaminosis A depresses enzyme function and it depletes nutrients needed for preventing the production of excessive oxalates.

Thiamine deficiency and oxalosis
Abstract
Type I hyperoxaluria results from reduced activity of α-ketoglutarate: glyoxylate carboligase, which is necessary for the synergistic decarboxylation of glyoxylate and α-ketoglutarate to α-hydroxy-β-keto-adipate.
Since thiamine pyrophosphate is a cofactor in the reaction, thiamine deficiency might be expected to result in tissue oxalosis. However, there was no significant increase in the incidence of renal oxalosis in 15 patients with Wernicke's encephalopathy at necropsy compared with controls.
It is possible that hyperoxaluria was present in these thiamine-deficient patients but at a urine concentration below that necessary for calcium oxalate deposition. It is also possible that the severity of the thiamine deficit required for hyperoxaluria exceeds that for the neuronal and cardiac manifestations.

Formation of Oxalate in Pyridoxine or Thiamin Deficient Rats during Intravenous Xylitol Infusions
Abstract
Glucose, fructose, sorbitol and xylitol were assessed as precursors of oxalate in normal rats and rats deficient in thiamin or vitamin B-6. Urinary excretions of oxalate, glyoxylate and glycine were increased significantly in vitamin B-6 deficient rats infused with xylitol when compared with all other groups. Using [U-14C]xylitol, oxalate was shown to be derived directly from this polyalcohol in vitamin B-6 deficient rats. These results suggest that vitamin B-6 deficiency may be a factor contributing to oxalate crystal deposition seen in some patients infused with xylitol.
@tim-2 I think (like other people who talk about them as harmful) oxalates are simply harmful due to mechanical damage. They are simply microscopic sharp crystals that are doing damage to the tissues. It is not about some biochemistry processes.. Same with gluten. It is simply very hard to digest protein structure that in lager enough doses will cause inflammation and digestive issues even if they don't have celiac or gluten sensitivity. How big issues someone will have with oxalates or gluten depends on his health status for sure. That's why healthy people can eat everything with no issues and people with bad health can't eat almost anything to avoid issues and the dose makes the poison which is very true in case of oxalates and gluten..
Last night I came out in a sore blemish right in the corner of my mouth (which I'm also going to blame on the raspberries)! It's very interesting to me that Grant's diet would have also been low in oxalates. (why does my body love to detox through the facial skin? ack)
I'm addicted to the Townsends historical food videos, and I'm always thinking about how they ate just a few foods re-arranged in myriad ways. Flour, Milk, Eggs, Butter, Lard, Meat.
Quote from Jiří on July 17, 2020, 9:27 am... I can't stop eating buchwheat pancakes.
It has been said "Pancakes Are Love".
They are a good example of a food made from those few ingredients our ancestors used constantly.
Whenever I was down with a Migraine or recovering from a food attack, pancakes are what I'd recover with.
@lil-chick yeah with buckwheat you don't need anything. Just water and flour.. I mix in egg whites for extra protein.. With some jam and banana on top hmm... 🙂
My other ancestors (the non-germanic ones) are from Nova Scotia, and they made a pancake called a Ploye, out of buckwheat.
One of the pictures here looks like what you mention (with the fruit). But they are also using them for sandwiches etc.
