The blood type diet was first written by Peter J. D’Adamo in 1996, recommends eating specific foods based on your blood type (O, A, B, OR AB) to optimize health. Everything is bio individual, meaning what works for one person might not work for the next person with the same blood type. This diet ultimately supports eating primarily whole foods, eliminating the consumption of processed foods and getting adequate daily exercise. I am by no means a doctor, nor am I recommending that you should eat 100% based on your blood type, but I do believe this information could be useful for some. At the end of the day, do what works best for you and eat what makes you feel good. Always remember, you are your own health advocate.
