A good way to see if you easily tolerate raw kale is to see what your digestive system does within 30 minutes of consuming it. If you eat a bowl of raw kale and find that you have to use the porcelain throne within minutes, then your digestive system is NOT ready to eat it raw. If you are fine 30-60 minutes after consuming raw kale, you have a strong enough system to be able to tolerate raw kale. Get yourself to the point where you can eat raw kale. That means consuming more natural fiber, prebiotic foods and probiotic foods. Also avoid sugary foods and processed foods.
