Similarly, I’m a bit disheartened that I’ve just tried coconut bread, which I really enjoyed but quickly seemed to bring on brain fog and a sinus headache. I also have some mild gas now, too. However, I was also eating eggplant and cabbage with olive oil, turmeric and cumin. The question then becomes: was the ‘reaction’ due to inadequate digestion or die-off? I guess the only way of knowing is to try it again. More and more I get sinus headaches from food.
