Iâm asking to get best food combining diet for my mom. Actually, my mom is taking only food combining diet and I have to take care of her diet so that acid build up is minimal. I have been noticed that you canât have croutons in chicken Caesar salad however it is permissible to have chicken sandwich with lettuce. Is it the same thing? Could you provide some best food combining diet? I want to some daily best food combining diet for less acid build up.
