This is SUCH a great question. As for the juice, I actually haven’t read that but know to keep fruits to a minimum for the sugar factor. You definitely don’t want it to be fruit heavy. It is a school of thought that combining fruit with your meal will lead to digestive upset (known as food pairing, putting certain foods together for optimal digestion). And I try not to eat fruit while I am eating other foods, only after I have eaten. I add it to my plate for photography purposes, but don’t take bites of fruit as I am eating eggs . . . if that makes sense! It can cause the fruit to ferment and lead to symptoms that some people attribute to other things, like gluten intolerance! The simple removal of fruit from a meal can take away that pain for some. I try to keep them separate, our fruit is always used more as a dessert. It might not help everyone because we are all so individual, but it’s made a difference for me. Even that small part of not eating it WITH other things. Some might need to remove it for 30-60 minutes after a meal to see if it has an effect.
Thanks so much for your comment!
