Food is the first priority of living beings. Human beings earn to eat, but the food we intake can be helpful for our health or harmful for us. According to some known doctors (dietician, nutritionists etc.) the food we intake, takes place as a chemical reaction with blood. This reaction takes place between lectin (diverse protein) and antigen of blood. In addition, as the outcome of this reaction so many diseases occupy space in human body.

Just to overcome this problem doctors proposed a new theory to eat the blood type diet food. This type of diet is used to prevent the weight gain and other health issues like cardiovascular disease and disease related to digestive system.

O Positive blood is also known as Rh+ blood or Rhesus blood because it has the rhesus antigen, which is positive. Blood is composed of four parts platelets, plasma, white blood cells and red blood cells. Antigens are the chemical markers present in the red blood cell. Only according to the type of antigens in the plasma of blood, blood types are decided. O type blood have no antigen but it have antibodies anti-A and anti-B.

People those have O positive blood group pursue stomach acid, which is very strong and respective digestive enzymes. Thus, they can metabolize everything. In O type people, some diets are especially responsible for weight gain. So, one should avoid them.

Like dairy products (cheese, butter, yogurt etc.). Wheat and its products: it has gluten, which slow down the metabolic rate by interfering with insulin. Legumes and beans contain lectins, which get collected in the tissues of muscle. Cauliflower, mustard and cabbage: reduce metabolic rate but also inhibit thyroid problems.

Blood group of a person decides the eating habits of a person and also, allergies, body metabolism, and other physical condition. The O positive blood type diet prevents various diseases and also helps avoiding infections. That is why reason people with O positive blood are suggested to consume seafood and meat on a large extent. Keep in mind that low carbohydrate and high protein foods are to be taken as O positive blood type diet.

If a person is following a particular diet, it is necessary to know what he eat, which helps to raise the metabolism and keep the unnecessary carvings stay off. If one follows, few things that they can snack on are fresh fruit juice, fruits such as banana, pears, fig etc., and vegetable soup (spinach, celery, cabbage and cucumbers).

Partially changing the daily food habits does not give any benefit of following the diet, if one wants a tremendous change then he has to be genuine with diet. In O positive blood type diet, one must follow rigorous cardiovascular exercise with proper diet. Another good option for maintain sound health is aerobics. If one tries aerobics along with proper diet, it will make him healthier as well energetic. And at last chocolates and processed foods can also be consumed but occasionally.
