Leyla Weighs In: Meal Replacement Shakes

Nutritionist Leyla Muedin answers this listener question: I’ve been making a meal replacement shake with raw greens, fruit, nuts, protein powder and fats like coconut and avocado oil. I do this to make sure I get enough nutritious food for the day. Is this a good idea? Will the uncooked greens such as spinach and kale contribute to oxalate build up in my kidneys, increasing my risk of kidney stones?
