The AB-positive blood group diet is a part of the blood type diet introduced by Dr Peter D’Adamo in Eat Right 4 Your Type. It is based on the idea that you should eat according to your blood type, as certain foods may be more compatible with your body. While scientific evidence is limited, this diet suggests that following this practice may improve digestion and overall health.
What is an AB positive blood diet?
An AB positive blood diet is a food pattern suggested by Dr D’Adamo that recommends choosing foods believed to suit the unique digestive and metabolic characteristics of people with AB blood type. It focuses on easily digestible proteins, fresh vegetables, certain dairy products and avoiding foods that may cause lectin-related reactions.
According to Dr D’Adamo, individuals with AB blood type share traits of both Type A and Type B. They have lower levels of stomach acid, similar to Type A, but also show Type B’s ability to digest meat. However, because the stomach acid level is not sufficient, meat may not be broken down efficiently, which can lead to it being stored as fat.
What to eat for AB-positive blood type
The AB-positive blood type diet blends A and B blood groups, making it the most flexible. A balanced diet rich in dairy, seafood, lentils, fresh fruits and vegetables is recommended for people following the AB blood type diet.
Foods like paneer, curd, rajma, moong dal, green leafy vegetables and even lean proteins like fish and chicken make for good choices.
It’s best to limit red meat, processed foods, alcohol and excess caffeine. Additionally, heavy grains like wheat and corn-based products should also be limited.
Why eating food by your blood type matters
According to D’Adamo, food items contain certain proteins called lectins that can stick to the antigens of your blood type. Due to this, you may suffer from skin issues, digestive problems, fatigue and headaches. When you take a diet according to your blood type, it can boost your energy levels and improve chronic conditions and digestion.
The renowned naturopathic physician also stresses how each blood type is prone to some diseases more than others. So, it is advisable to follow a blood type-based diet to lower your chances of getting infected in the long run.
Foods AB positive blood group should avoid
There are certain food items that people with an AB+ blood group should not consume:
- Bacon, beef and ham
- Kidney beans
- Diet soda and regular black tea
- Buttermilk, ice cream and whole milk
- Barley flour
- Sunflower and cottonseed oil
- Pumpkin seeds, sunflower seeds and sesame seeds
- Orange juice
Role of health insurance while following an AB positive diet
When following an AB+ specific diet, you might want to take up nutritional counselling to ensure that you are on the right track. That’s where a good medical insurance comes in, as it can cover the dietitian visits, depending on policy terms.
Furthermore, even though this diet pattern suggests improved digestion and reduced risk of certain conditions, health needs can still change over time. Having comprehensive family health insurance in place ensures that medical care, diagnostics or hospitalisation are financially supported when required. It also allows access to preventive health check-ups, which can help you monitor progress and detect concerns early.
Conclusion
Although the blood type diet has been prevalent for a long time, several nutritional experts have claimed it to be a gimmicky way of helping people eat cleaner and healthier. So, you can follow the AB+ diet and improve the nutritional value of your meals in the long run.
