The chuck example is valid only if it indicates that many or all herbivorous reptiles can tolerate a high oxalate diet. Otherwise it may be an example of one animal that has adapted to such a diet that would otherwise be harmful.
In other words we need proof before we can generalize to other animals.

If you look up "kidney stones" and "oxalic acid" you will find many recommendations that humans at risk of kidney stones reduce their intake of foods containing oxalates. These foods include spinach, etc. Plus oxalic acid does bind with calcium, reducing its availability.

Finally, kale is considered high in substances that interfere with iodine, leading to goitres.
Other foods from the same group (Brassica) as kale are also high in oxalic acids. These include collard greens.

I'll need more proof before I decide to give my tortoises more high oxalate foods in their diet. Until then, I'll balance out the diet and try to keep high oxalate foods in the minority.
