The Type B Diet – Overview


The Type B diet is balanced and wholesome and includes a wide variety of foods.  It represents a blending of several different cultures, and provides you with the choice of the best from the animal and vegetable kingdoms.  The sturdy and alert Type B’s are usually able to resist many of the most severe diseases common to modern life, such as heart disease and cancer.  Even if they do contract these diseases, they seem more likely to survive them.  Due to the particular construction of their immune system, they are prone however to chronic viral infections and slow growing viruses, such as Multiple Sclerosis, Chronic Fatigue Syndrome and Lupus.

Foods below are presented under their broad headings as either beneficial, neutral or avoid.  Try to eat as many of the beneficial foods as possible, the neutral foods to fill out your diet and avoid the rest as often as possible.  Following the diet accurately will lead to benefits within 1-2 weeks of greater energy, reduction in symptoms of illness and fat loss (should that be necessary for your body).

Stress Profile


Stress is a highly personal experience, and what is incredibly stressful for one person may not create any problems for another.  How we deal with stress is more important than the absolute level of stressful events that occur in our lives.  Your blood type influences how you deal with stress and should guide your stress management techniques.

Type B’s response to stressful life events represents a balance between the intellectualising of the event and a physically aggressive response to a challenge.  They are able to respond to different stresses in different ways, depending on what is required at the time.  This represents an evolutionary adaptation to the needs of the people at the time, who required both the aggression and stamina to fight and conquer new lands, with the creativity and sensitivity to cultivate and develop these new lands into civilizations.

Type B’s should aim to exercise regularly, and participate in activities that balance the physical demands against mental diversion.  They are often most comfortable performing exercises of moderate intensity, in the company of other people.  Some suggestions would be group bushwalking, tennis, aerobics classes, group cycling and less aggressive martial arts.  You will tend to be less effective and get less enjoyment from fiercely competitive sports such as rugby or boxing.




Type B’s should exercise at least 3-4 times per week to get the best results.

Tennis 45-60 3

Weight Loss


The single largest factors for weight gain in Type B’s are corn, buckwheat, lentils, peanuts and sesame seeds.  Each of these foods contain a lectin which will interfere with your insulin levels, leading to fatigue and possibly hypoglycaemia (low blood sugar levels).  If you are trying to lose weight, wheat should also be avoided.  It will slow the metabolism and cause more food to be stored as fat rather than burned for energy.  Most Type B’s who stay on the diet will achieve a normal weight easily, all that is required is that you stick with the program.  Because the type B diet allows dairy foods, if you are trying to lose weight you should only consume these in moderation.  They are actually beneficial for your metabolism, but only if consumed in moderation.

Foods interfering with Fat Loss

Green vegetables





Sesame seeds




Meat, Offal, Poultry and Game


Whilst Type B’s have a good choice of meats, there are several that should definitely be avoided to maximise your health.  Perhaps the hardest for most Type B’s to give up is chicken, which contains a lectin that strongly affects your system.  If you are accustomed to eating chicken, you may swap to turkey or pheasant, neither of which have the dangerous lectin.  If stressed or fatigued, you will cope much better by eating only those meats in the beneficial column, and minimising those that are neutral until you are back in balance.

Highly beneficial Neutral Avoid
Lamb Beef Bacon Heart
Mutton Liver – calf, chicken, pig Chicken Partridge
Rabbit Pheasant Duck Pork
Venison Turkey Goose Poussin
Veal Ham Quail




Type B’s thrive on seafood, especially cold water fish like cod, salmon and tuna, which are high in beneficial omega-3 oils.  White fish such as cod, halibut and sole are excellent choices as well.  You will need to avoid all crustaceans (crabs, lobsters, prawns, mussells, oysters etc) as they contain harmful lectins for the Type B system.

Dairy Food and Eggs


Type B is the only blood type that can fully enjoy a variety of dairy foods.  The primary blood cell marker (D-galactosamine) is the same sugar that is present in milk.  Dairy was first introduced into the human diet at the height of blood Type B development, along with the domestication of animals.  Type B’s of Asian descent may be unaccustomed to eating dairy, as there has been a long cultural distaste for dairy foods.  Dairy was first introduced to Asia with the Mongolian hordes, and it has long been seen as the food of the barbarian.  This is unfortunate, as there are a large number of Type B’s in Asia whose soy-based diets are damaging their health.

Similarly, Type B’s of African descent may have difficulty with dairy, as many are lactose intolerant.  This is not an immune reaction, it is a digestive intolerance which can often be overcome by slowly adding dairy to the diet.  Digestive enzymes can be beneficial to reduce any discomfort that people may experience from consuming dairy foods in the early stages.

Hens eggs are beneficial on the Type B diet, as they are a good source of nutrients, and do not contain the damaging lectin found in chicken.

Oils and Fats


You will benefit from introducing olive oil to your diet.  You can use one tablespoon every second day in cooking or salad dressing.  Ghee (clarified butter) can also be used as a cooking oil.  Avoid using sesame, sunflower or corn oils which are harmful to your digestive tract.

Highly beneficial Neutral Avoid
Olive oil Cod liver oil Canola Safflower oil
Ghee Corn oil Sunflower oil
Linseed (flaxseed) oil Cottonseed oil Sesame oil


Nuts and Seeds


There are no highly beneficial nuts and seeds for the Type B diet.  Peanuts, sesame seeds and sunflower seeds contain lectins interfering with insulin regulation.

Highly beneficial Neutral Avoid
None Almonds Cashew nuts Poppy seeds
Brazil nuts Hazelnuts Sesame seeds
Chestnuts Peanuts Sunflower seeds
Hickory nuts Peanut butter Tahini
Macadamia nuts Pistachios
Walnuts Pine nuts


Beans and Pulses


Type B’s may eat some beans, but need to avoid lentils, chickpeas, pinto beans and others, which contain lectins that interfere with insulin regulation.  If you are of Asian descent you may cope better with beans and pulses than others, as you will be more culturally accustomed to eating them.  Even so, you should limit your exposure to these foods.

Highly beneficial Neutral Avoid
Kidney beans Broad beans Aduki beans
Lima beans Cannellini beans Black beans
Navy beans Green beans Black-eyed beans
Mangetouts Chickpeas
Peas – green, sugar snap Lentils – green, brown, red
Red soya beans



When Type B is in balance – following the basic principles of the diet – wheat may not be a problem.  However, wheat is not tolerated well by most Type B’s as the gluten contains a lectin that will deposit in the muscle tissues and interfere with metabolic efficiency.  Food that is not burned for energy will generally be stored as fat, so wheat can be a factor in Type B weight gain.  It has also been found that Rye can cause blood vessel problems for Type B’s and is best avoided.  The key is balance – try to eat a variety of grains, especially rice and oats.

There are few fruits that you should avoid, and you probably won’t miss things like Prickly pear or pomegranate anyway.  Pineapple is a good choice, especially if you are susceptible to bloating from the dairy etc, as it contains Bromelain, which is an enzyme that will assist digestion.  Try to consume at least 1-2 pieces of fruit per day.

Herbal Teas


You will not reap enourmous benefits from most herbal teas, but neither are there many that are harmful to your system.  Ginseng is highly recommended and has a positive effect on the nervous system.  Licourice can also be used for it’s anti-viral and energy boosting properties.
