Hi Spysr
I always thought I was sensitive to fats and had problems digesting them to the point of HB.Recently however, I've discovered that as long as I don't have any bread or grain with my salad the olive oil doesn't bother me.You say you're food combining so you won't be eating bread with tuna.You could look at anything else that might be in the salad that is difficult to digest---2 tablespoons of olive oil is quite a lot for an individual salad (for me)apart from that I can't really help maybe someone else has a suggestion.--sorry
