Eating all of these foods can come in time, but for me, it took about 1 year of the diet to heal leaky gut. During stage 2 you can start to eat more fruits, which reduce inflammation and can heal the gut. I personally would have the leaky gut reaction to green apples earlier in my treatment but in time it went away. Occasionally you can cheat of course and have a green apple…I would consider trying it out after 2-3 months on the diet to gauge your progress.
I ate blueberries throughout my treatment with no setbacks but everyone is different of course. I eat about 15 blueberries per day with my yogurt which contains about 8g of sugar. Blueberries and anti-inflammatory and have other health benefits.
