While green juice can be a beneficial addition to a balanced diet, it's crucial to consume it in moderation. Green vegetables, being rich in oxalic acid, can indeed bind to minerals and potentially interfere with their absorption in the digestive tract. Excessive consumption of oxalate-rich foods may contribute to the formation of kidney stones in susceptible individuals. Therefore, varying the types of vegetables in your green juice and balancing it with other nutrient sources is key to reaping the benefits without exceeding recommended levels of oxalate intake (Reference: Lincoln University.)
