His theory states that each blood group contains its own unique antigen (an antigen is any substance that causes your immune system to produce antibodies against it) marker, which has a tendency to react badly with certain foods, thereby leading to potential health problems.D'Adamo believes that because blood types evolved at different times throughout history, we should eat a diet based on the types of foods our ancestors typically ate at the time.
But last week scientists discovered there could be another surprising reason why so many struggle to perform – their blood type.
A study showed men with blood types A, B or AB are up to four times more likely to suffer impotence – than men who have blood type O.
A new test can identify a patient's blood type in just a few seconds with 99.9 per cent accuracy, a study shows.
Current methods to determine whether someone in a life-threatening situation is an A, B, AB or O are slow and technically demanding.
The results appeared as visual colour changes - teal if a blood group antigen was present in a sample, brown if not.
With slightly more time - but still in less than two minutes - the test was able to identify multiple rare blood types.
Blood group AB : According to D'Adamo, this is the most recent evolved type, arriving less than 1,000 years ago.
In terms of dietary needs, his blood type diet treats this group as an intermediate between blood types A and B. Naturopathic physician Peter D'Adamo charted out the Blood Type Diet in his book, Eat Right 4 Your Type.
Nutritionist and naturopath Zainab Syed explains, "As per the diet, the compatibility or incompatibility of protein lectins found in the food we eat with the blood type antigens targets various body organs or the system." If you're toying with the idea of trying out this diet but are quite impatient when it comes to seeing the results, no need to fret as depending on the age, health concerns, genetic disposition, it would take minimum of a week to about three weeks to see the result of this diet.
Benefits The diet suggests consuming more natural foods and therefore cuts down the intake of processed food, junk food, alcohol and chocolates.
The Turkish findings are potentially significant as it’s estimated more than half of all men carry A, B or AB blood.
