Beets occupy a confusing middle ground. They're vividly colored, packed with nitrates that athletes love, and frequently appear in "superfood" lists. But for kidney stone patients, they come with a caution label: 48 mg oxalate per half-cup serving. That's moderate — above the 25 mg safe line, below the 100 mg avoid line. Portion is everything here. A few slices of pickled beets on a salad? Fine. A full beet and goat cheese salad as your main lunch? That's pushing it. Also worth knowing: the oxalate is concentrated in the root, not the greens (though beet greens are their own high-oxalate problem).
