Blood Type Diet: Each blood type has a unique composition of digestive enzymes that determines how the body will react to different food groups. Basically, your blood type has a distinct way of recognising what is “alien” for you. When the body perceives a threat from such an “alien”, it reacts violently, often leading to a host of health problems.
People with type O blood, like my husband, are more prone to stomach problems because of the high acidic content in the stomach. So while they can digest protein well, they have to be cautious about consuming too many fats or carbohydrates. They are also known to have a sluggish metabolism so they must exercise regularly and avoid grains and heavier oils made from corn or peanut. Fresh fruits such as berries, plums, bananas and pears are beneficial as they are “friendly” with the typical stomach enzymes of those who have type O blood.
Of the four basic types, people with type B blood have the most resilient digestive systems. They usually aren’t overly sensitive to food choices. ‘They are lucky that their bodies aren’t averse to grains, meat or dairy. They should just aim at a balanced diet with lots of green vegetables – corn, lentils, tomatoes and peanuts are best avoided,’ advises Dr Eti.
On the other end of the spectrum are people with blood group A. Some studies suggest that these people have a low acidic content making it difficult for them to digest meat. Dr Eti says: ‘This group has shown a tendency towards cardiac problems. So for them we recommend a vegetarian diet with restricted animal fat and dairy products – intake of plenty of fruits and vegetables lowers the risk of cardiovascular disease. Since they also have thicker blood, it’s best for them to avoid fatty meat.’
This group combines the vulnerabilities of both A and B groups and falls in the sensitive zone. People with this blood type fare better with a diet that’s more vegetarian in nature. Since they don’t have enough stomach acid, they should – as far as possible – avoid dairy, alcohol, caffeine and citrus fruits.
