Blood Type & Your Health


A few weeks back, we had a great Friday Forum with Dr. Alicia Miller of the Natural Care Clinic. She spoke on the benefits of eating right for your blood type. I did not know anything about this topic before listening to her very informative lecture and thought that I would share some of the highlights, as I think this could really benefit people who may be dealing with some health issues and not responding to treatments. It certainly couldn’t hurt to follow these guidelines or ever try it for a short time and see how your body responds. Here are some of her notes condensed (somewhat) for the sake of blogging about it.


What foods we absorb well and how our bodies handle stress differ in each blood type. Consuming foods that work for you is the key to health, longevity, fitness and emotional well being. Dr. Peter D’Adamo is the author of “Eat Right 4 Your Type” and has been studying this theory for 15 years. He believes your blood type is a powerful genetic fingerprint that identifies you as surely as your DNA. In Japan blood type has long been associated with personality type. You might well be asked your blood type on a job interview. When you use the individualized characteristics of your blood type as a guidepost for eating and living, you will be healthier, reach your ideal weight and slow the process of aging.


Blood type O is the oldest blood type. People who have this type blood can be powerful and productive, however, when stressed they can become angry, hyperactive and impulsive. If type O wiring gets crossed, as a result of a poor diet or lack of exercise, they are more vulnerable to negative metabolic effects, including insulin resistance, sluggish thyroid activity and weight gain. They may also be predisposed to certain illnesses, such as ulcers and thyroid disorders.

Main foods that are beneficial for Type O’s:
Seafood (wild caught)
Iodized salt (not table salt)
Red Meat (lean, antibiotic & growth hormone free)
Organic Kale, Spinach and Broccoli

Main foods that Type O’s should avoid:

Wheat & Gluten
Kidney & Navy Beans
Cabbage, Brussell Sprouts, Cauliflower & Mustard Greens
Dairy, alcohol and caffeine

Type O’s most often described themselves in ways related to the following characteristics; responsible, decisive, organized, objective, rule-conscious and practical. They use all 5 of their senses well and are more detail and fact oriented. They are, however, more vulnerable to destructive behaviors when overly tired, depressed or bored. These can include gambling, risk taking and substance abuse.


Type O’s benefit tremendously from brisk regular exercise that taxes the cardiovascular and muscular systems 3-4x/week for 30-45 minutes. They have a better emotional response when exercising regularly and more than any other blood type, O’s rely on physical exercise to maintain physical health and emotional balance. If easily bored, O’s should choose two or three different exercises and vary their routines.


Blood Type A’s flourish on a vegetarian diet. If you are accustomed to eating meat, you will lose weight and have more energy once you eliminate the toxic foods from your diet. Many people find it difficult to move away from the typical meat and potato fare to soy proteins, grains and vegetables. It is particularly important for sensitive Type A’s to eat their foods in as natural a state as possible; pure, fresh and organic. According to Dr. D’Adamo, low levels of intestinal alkaline phosphatase in the stomach make it difficult for Type A’s to digest and metabolize animal protein and fat.

Main foods that are beneficial for Type A’s:
Vegetable Oils (organic, non-GMO)
Soy Foods (organic, non-GMO)
Vegetables (organic, non-GMO)

Main foods that Type A’s should avoid:
Dairy Foods
Kidney and Lima Beans

In this busy, ever changing world it’s almost impossible to avoid everyday stress. Type A’s have a naturally high level of the stress hormone cortisol and produce more in response to stressful situations. Due to the naturally elevated cortisol in Type A’s, additional stress often manifests in several ways; disrupted sleep patterns, daytime brain fog, increased blood viscosity (thickening) and promotes muscle loss and fat gain. In extreme cases in Type A’s, stress can manifest in more serious ways, causing obsessive-compulsive disorder, insulin resistance and hypothyroidism. To help balance cortisol levels, Dr. D’Adamo recommends that you limit sugar, caffeine and alcohol. Don’t skip meals, especially breakfast and eat smaller, more frequent meals to help stabilize blood sugar levels. The following factors are known to increase cortisol levels and increase mental exhaustion for Type A’s – be aware and limit your exposure when possible:

  •  Crowds of people
  •  Loud noise
  •  Negative emotions
  •  Smoking
  •  Strong smells or perfumes
  •  Too much sugar and starch
  •  Overwork
  •  Violent TV and movies
  •  Lack of sleep
  •  Extreme weather conditions (hot or cold)

Type A’s benefit from gentle exercise, such as Yoga, walking or Tai Chi.


Blood Type B have the most flexible dietary choices as they have a tolerant digestive system and a strong immune system, however, they tend to be highly sensitive to the effects of slipping out of balance. Type B’s tend to have a greater ability to adapt to altitude and are statistically the tallest of the blood types.

Main foods that are beneficial for Type B’s:
Green Vegetables
Eggs/low-fat dairy products (organic, free range)

Main foods that Type B’s should avoid:
Sesame seeds

When it comes to hormones, Type B is closer to Type A, producing somewhat higher levels of cortisol. When a Type B is out of balance this manifests in overreaction to stress, difficulty in recovering from stress, disrupted sleep patterns, brain fog and suppressed immune function. This leads to increased risks for depression, insulin resistance and hypothryroidism. They are also susceptible to slow growing, lingering viruses, such as those for multiple sclerosis, chronic fatigue syndrome and lupus.


Blood Type AB reflects the mixed inheritance of their A and B genes. According to Dr. D’Adamo, “Type AB has Type A’s low stomach acid, however, they also have Type B’s adaptation to meats. Therefore, you lack enough stomach acid to metabolize them efficiently and the meat you eat tends to get stored as fat.”

Main foods that are beneficial for Type AB’s:
Tofu (organic, non-GMO)
Seafood (mahi-mahi, red snapper, salmon, sardines and tuna)
Dairy (organic)
Green vegetables

Main foods that Type AB’s should avoid:
Red Meat
Kidney and Lima beans

Type AB should avoid caffeine and alcohol, especially when they are in stressful situations and avoid all smoked or cured meats, as these can cause stomach cancer in people with low levels of stomach acid. They should eat smaller, more frequent meals as they will counteract digestive problems. They will digest and metabolize foods more efficiently if they avoid eating starches and proteins in the same meal.


Type AB often receives mixed messages about emotional health. While they tend to be drawn to other people and are friendly and trusting, there is a side of them that feels alienated from the larger community. They are intuitive, spiritual and passionate in their beliefs but also want to be liked by others which can create conflicts. The greatest danger with Type AB’s is the tendency to internalize their emotions, especially anger and hostility, which is much more damaging to their health than externalizing it. Exercise plays a critical component in stress reduction and maintaining a healthy emotional balance for Type AB. A combination of both calming activities, such as Yoga or Tai Chi two days a week and a more intense physical exercise like running or biking three days a week is recommended for optimal balance.


Dr. Miller discussed many other topics related to the Blood Type Diet, however, I am unable to cover them all in this simple blog. If you would like more information you can contact her directly at (331) 457-5062 or visit her website at My blood type A body, does not think she can give up meat completely but I can certainly limit it and add more pineapple to my diet.  I was very surprised that 9 out the 10 items that I should avoid, I already make a conscious effort to avoid because they drive me crazy.  Now I know why, it’s in my blood. Fascinating stuff!!


Mark your calendars for our first Friday Four O’Clock Forum of 2014, January 24th!  Dr. David Lawrence of “Second Act Coaching” will discuss five important things you can do to have a spectacular and memorable second act. The skills that we learned in the first part of our lives are quite different from the ones we need as we get older. If you are feeling confused or stuck at this period of your life, this might be the perfect talk for you to attend.
