Swiss Chard

Those long stalks, look an awful lot like celery.
Anyone tried eating them like celery ?

Oxalates are found in many foods, including spinach and beet greens. Here is a detailed article about what they are, what they do, and why some people might need to limit them.
I love Swiss Chard but shops don't carry it. Apparently it doesn't store well or long enough.

Swiss chard stems are not as tough and stringy as celery and I never throw them away. I usually cut them into short lengths and start cooking them a bit before the leaves.

Thank you all.
To be on the safe side, I'll stick to cooking them.
