Those of you who happen to be looking for a new diet that might work for you may be looking into the eating right for your blood type diet. This diet preaches that your blood type is directly responsible for how your body will react to the food you eat. It also states certain things about ethnicity and where you are in regards to the things you should eat in order to maintain the highest amount of weight loss and the healthiest body. However, could this be true? There are many people on both sides of this fence, but if you look at some of the facts, it makes it easier to decide whether or not to believe this new diet trend.
The book written about this diet and how it all works states that blood types evolved at the same time as we did as a species. According to this book, blood type O came first, because at that point the human race was simply a giant group of hunter gatherers. Then came blood type A, which came when humans moved to being more agricultural. Blood type B came last, and it was a result of a diet high in grains, vegetables and meats.
Problems with the Blood Type Theory
The first problem with this theory is that this isn't the real reason why there is more than one blood type. Type A and B are perfect genes, while type O is an abnormality. There is no way that an abnormal blood type could have come first and spawned two normal ones. Scientists have proven that type A and B diverged at least thirteen million years ago, which directly contradict what the creator of this diet fad uses as the base for his diet--by proving that this change in blood types occurred before ape became man.
Ethnicity is another factor brought into the light with this new diet, and certain foods are given for each individual race as well. There is one thing that this piece fails to take into consideration, and that is the diversity of blood types within certain populations and how they can be followed back to an evolutionary defense against viruses and bacteria. These differences have no connection to food intake.
There are many reasons to not trust the latest diet fads, and most of them are thrown out months after being in the spotlight once they are found to not work. The power of suggestion is great on the mind, and even the simple action of telling someone that something will cause them to lose weight could give them more self esteem and cause them to lose more weight, just because they have been told they will. Both nutritionists and dieticians have spoken out publically against this diet trend, and there has been no scientific data given to prove how it works...or that it works at all.
