    I tend to naturally eat toward my blood type, and my cravings and preferences are generally correct to my type. The dairy warning for type A’s were spot on for me. I suffered for years, and then I completely eliminated dairy and I feel much better. However, there are some on the good list that my stomach cannot tolerate (especially as I get older). And, there are some on the avoid list that don’t bother me so much. Overall useful guidelines, and I plan to incorporate it more. into my daily intake.

      Thank you for your kind comments.

      We can see that The blood type diet do have its variation due to each person own health. Due to tremendous variation in individual constitution, there is no guaranteed success with it. If you would like to follow the blood type diet, I would recommend that you follow it vigorously for 3 months, even though you don’t see much harm or benefit in certain food. After 3 months, if you see no improvements in your health, then you can deviate and use the blood type diet as a general guideline and not overeat the foods that should be avoided for your Blood Type, but take them with care and in small amounts.
