While taro is generally considered a nutritious food, there are a few considerations to keep in mind. Taro contains oxalates, which can interfere with calcium absorption and may be problematic for individuals with kidney issues or a history of kidney stones. Additionally, taro should be cooked thoroughly before consumption, as raw taro contains calcium oxalate crystals that can cause skin irritation and throat discomfort. Proper preparation and cooking methods help mitigate these potential disadvantages.
