Is the fountain of youth found in your blood type?

IS EATING a diet based on your blood type the key to the fountain of youth? Helping you lose weight, be healthier, reduce stress and give you greater understanding into your personality?

Blood-type diet innovator naturopath Peter D'Adamo claims foods react chemically with blood and if you follow a blood-type designed diet you gain all of the above, and may even prevent disease, helping you to live younger, for longer.


Type Os - Must go light on grains, beans and dairy, having various supplements to help with tummy troubles renowned with type Os. Opt for these instead: lean meat, poultry, fish, vegetables.

Type As - Ideally benefit from organic and fresh ingredients, due to sensitive immune system; meaning they should concentrate on: a meat-free diet, fruits and vegetables, beans and legumes, whole grains.

Type Bs - Should avoid corn, wheat, buckwheat, lentils, tomatoes, peanuts, sesame seeds and chicken, instead check out the fresh food aisles for: green vegetables, eggs, certain meats, low-fat dairy.

Type AB - Have a tendency for low stomach acid and should avoid caffeine, alcohol, and smoked or cured meats, instead choose from: tofu, seafood, dairy, green vegetables.


Did you know a drop of blood contains a biochemical make-up as unique to you as your fingerprint? Therefore, knowing your blood type is important for understanding your natural reaction to stress.

Type Os - When stressed, type Os are prone to bouts of: excessive anger, temper tantrums, hyperactivity, and, worst case scenario, severe chemical imbalance resulting in a manic episode.

Type As - Have a naturally high level of the stress hormone cortisol and need to be aware of and limit exposure to: crowds, loud noise, negative emotions, smoking, strong smells or perfumes, too much sugar and starch, overworking, violent shows, lack of sleep, extreme weather conditions (hot or cold).

Type B - Similar to type A, producing higher levels of cortisol, and when type B is out of balance, it manifests in: overreaction to stress, difficulty in recovering from stress, disrupted sleep patterns, daytime brain fog, suppresses immune function.

Type ABs - Most resemble type O in a tendency to overproduce catecholamine, married with the additional complexity of type B's rapid clearing of nitrous oxide, thus suffering: physical consequences of high emotions, tendency to internalise emotions, especially anger and hostility, which is much more damaging to health than externalising it.


Exercise is a mixed blessing when it comes to stress. A high level of physical fitness will definitely allow the nervous system to recover more rapidly from stress. A moderate amount of physical activity on a consistent basis will also tend to reduce the overall stress response.

But just like your diet, Dr D'Adamo claims each blood types benefit from different styles of exercise.

Type O - Regular physical activity three to four times a week; aerobic activity of 30-45 minutes at least four times a week; choose two or three different exercises and vary your routine.

Type A - Hatha yoga; tai chi; meditation; deep breathing exercises.

Type B - Tennis; martial arts; cycling; hiking; golf.

Type AB - Combine calming activities with more intense physical exercise; for example, three days of aerobic exercise such as running or biking and; two days of calming exercise, such as yoga or tai chi.


In addition to exercising and eating foods right for your type, Dr D'Adamo offers a range of lifestyle strategies he claims are ideal for each blood type.

Type O - Develop clear plans for goals and tasks to avoid being impulsive; make gradual lifestyle changes; eat all meals, even snacks, seated at a table; chew slowly and put your fork down between bites of food; avoid big decisions or spending money when stressed; do something physical when you feel anxious.

Type A - Establish a consistent schedule; go to bed before 11pm for at least eight hours' sleep; don't linger in bed, as soon as you get up, go; take at least two breaks of 20 minutes during work; stretch, take a walk, do deep breathing exercises or meditate; don't skip meals; eat more protein at the start of the day, less at the end; don't eat when you are anxious; eat smaller, more frequent meals.

Type B - Visualisation is a powerful technique for Bs - if you can visualise, you can achieve; find healthy ways to express your non-conformist side; find 20 minutes a day to be creative - something requiring complete attention; go to bed before 11pm for at least eight hours' sleep; meditate during breaks; find meaningful connections through a community, neighbourhood or other group.

Type AB - Cultivate your social nature in welcoming environments, avoiding highly competitive ones; avoid ritualistic thinking and fixating on issues; develop a clear plan for goals and tasks; make lifestyle changes gradually, rather than trying to tackle everything at once; engage in 45-60 minutes of aerobic exercise at least twice a week, balanced with daily stretching, meditation or yoga; find meaningful connections through a community, neighbourhood or other group; practice visualisation techniques daily; alone time - have at least one sport, hobby or activity to perform independently; break up your workday with physical activity.

While you can't change your blood type, D'Adamo recommends using this knowledge to implement a dietary plan biologically suited to your make-up.

"Most of my patients experience some results within two weeks of starting the diet plan - increased energy, weight loss, a lessening of digestive complaints, and improvement of chronic conditions such as asthma, headaches, and heartburn."
