Blood Type O Diet

The type O blood is the most common blood type in the world. Nearly 40 percent of the global population has type O blood. Researchers believe that O type blood was perhaps the first human blood group. Other blood groups emerged through the gradual evolutionary process. People with type O blood carry certain unique physical and behavioral traits, which are different from individuals with A, B or AB blood type.

Health problems in people with type O blood



Compared with other blood types, people with type O blood group have higher acid content in their stomachs. They are more vulnerable to acidity, stomach ulcer and irritation. Incidence of thyroid disorder is greater among O type individuals. They tend to have low levels of thyroid hormones. People with O type blood group often suffer from iodine deficiency, which worsens thyroid malfunction. Poor thyroid function lowers the metabolism of the body leading to weight gain and fatigue. Type O individuals are most susceptible to stress. Excess secretion of stress hormones might increase the risk of weight gain.

Blood type O diet



The diet of our hunter-gatherer ancestors is most suitable for people with type O blood. The high stomach acid provides an amicable environment for digesting proteins. O type individuals could easily metabolize animal protein. A high protein diet comprising of lean meat, fish, seafood and poultry is suitable for O type individuals. However, type Os might find it difficult to metabolize grains, beans, legumes and dairy products. Intake of these food items is associated with weight gain in people with type O blood.

Gluten, a type of protein present in wheat, tends to lower the metabolism rate, leading to lesser calorie usage, which leads to fat deposition. Lectin present in legumes and beans accumulates on the muscles, reducing stamina for physical activities. Since people with type O blood have a greater risk of suffering from thyroid problems, they should consume iodine rich foods and limit intake of foods that might slow down secretion of thyroid hormones. If you have type O blood, you should limit intake of cruciferous vegetables such as cauliflower, broccoli, cabbage and Brussels sprout. Vegetables of the nightshade family might not be good for your health.
