Pseudoscience is defined as a collection of belief that is thought to be based on scientific evidence, when in reality, no scientific evidence is used to prove that the belief is valid. Even today, pseudoscience is still being applied in advertisements and sponsored commercials. A well known example of pseudoscience is the food diet called the “Blood Type Diet.” This diet was created by naturopath, Dr Peter D‘Adamo. and he perceives that different blood types have different ways of dealing with certain nutrients due to the unique antigen markers on each blood cell.
He provides a solution of a Blood type Diet. where the person digests a designed diet specifically for his or her blood group, and the designed diet is based on what types of food that our ancestors ate when the blood type was first recognized (blood types evolved at different times through history).
There are four types of blood groups and each one apparently evolved at different times in history.
First, Dr. D‘Adamo presents the idea that blood type 0 ancestors were the first people to ever live, and he proposed that they mostly lived on a meat-based diet. thus people who have type 0 blood should eat a high protein meat diet due to the fact that it is what supports his theory. Then, blood type A came into existence and these people mostly ate vegetations from plantations, so people today with blood type A should consume a vegetarian diet.
After this, blood type B evolved, and these people ate a mix of both meat and vegetables, while the last blood type, AB, can consume both foods initially taken in byAand B.
However, to disprove this claim and prove that what Dr. D’Adamo is recommending is guided by mere pseudoscience, it should be understood that blood types do not determine the diet should take and the fact that this diet has a possibility of working is because of the fact that using this diet eliminates certain foods, such as fats and processed foods. Overall, the use of the Blood Type diet is unreliable due to its unsupported scientific facts and its reliance on pseudoscience as a source of legitimacy.
