Risk profile
Safety & processing
Both Water Bamboo and Bok Choy are whole, minimally processed vegetables typically sold fresh. Neither carries significant processing concerns. The main consideration is that canned Water Bamboo may contain added sodium, so fresh or frozen is preferable.
Water Bamboo
Aquatic environment contamination
mediumWater Bamboo grows in water and can accumulate heavy metals or pollutants from contaminated waterways. Source quality matters more than with soil-grown vegetables.
Parasite risk from raw consumption
lowAs an aquatic plant, raw Water Bamboo may carry parasites uncommon in land vegetables. Cooking eliminates this risk.
Bok Choy
Pesticide residue on non-organic varieties
mediumBok Choy frequently appears on the Dirty Dozen list for leafy greens. Washing thoroughly or choosing organic reduces exposure.
Goitrogenic compounds when consumed raw in large amounts
lowRaw Bok Choy contains goitrogens that can interfere with thyroid function if consumed in extreme quantities. Cooking largely neutralizes this concern.
