4 Your Type: How Dr. D’Adamo Built an Innovative Health Brand By Determining a Link Between Blood Type and Well-Being

By: Jon McDonald

The Crunch: In 1996, Dr. Peter D’Adamo followed in his father’s footsteps and wrote “Eat Right 4 Your Type,” a New York Times bestseller that introduced the health and wellness world to The Blood Type Diet. Unlike many mass-marketed diets that wane in popularity, The Blood Type Diet has retained a strong following through continued research, publications, and product development. With over 7 million followers, D’Adamo Personalized Nutrition has grown into a marketplace of education and products to support those who have found the Blood Type Diet to be a viable solution for their health and wellness. By channeling research in glycobiology into individualized diets and solutions for better living, D’Adamo Personalized Nutrition continues to grow into an innovative health and wellness brand.

As with many other health professionals, Dr. James D’Adamo’s experience as a naturopath solidified his convictions about the strong connection between the foods people eat and their overall health. But, instead of directing his focus to nutritional quality, Dr. D’Adamo’s observations led him to believe that the ideal diet for each person has more to do with his or her unique biological profile — specifically, blood type.

Inspired by his father James’ groundbreaking 1982 book “One Man’s Food is Someone Else’s Poison,” Dr. Peter J. D’Adamo set out to validate his clinical observations with scientific study. By 1990, Dr. D’Adamo had become an award-winning naturopathic doctor and an expert in the field of glycobiology – the study of carbohydrate molecules and the role they play in the human body.

Dr. Peter J. D’Adamo wrote “Eat Right 4 Your Type” based on his extensive research.

Dr. D’Adamo discovered that a protein known as lectin, found in many foods, reacts uniquely with different blood types and can interfere with body tissues, digestive health, and kidney function. Blood type also appeared to influence which diseases people are more susceptible to, what kind of gut bacteria they produce, and even how they react to environmental influences and stress.

In 1998, Dr. D’Adamo published his findings in his book “Eat Right 4 Your Type,” a revolutionary approach to nutrition that uses the individual’s biological profile to determine the best diet for optimum health and well-being. An instant New York Times bestseller, “Eat Right 4 Your Type” introduced nutritional genomics to the world stage and spawned Dr. D’Adamo’s popular D’Adamo Personalized Nutrition health and wellness brand.

By continuing to provide the public with follow-up research, publications, products, and support in living out the blood type diet, the D’Adamo Personalized Nutrition company has successfully expanded “Eat Right 4 Your Type” beyond a bestselling book into a health and lifestyle brand. Today, D’Adamo Personalized Nutrition draws 7 million followers and continues to support an active community of people who connect with the concept of a nutritional approach rooted in genetics.

Blood-Type Specific Guides to Optimize Diet and Lifestyle

Dr. D’Adamo has continued to study and write — publishing more than 46 books related to the blood type diet over the last 20 years — about how the four blood types and other genetic markers affect every aspect of a person’s health and lifestyle. The D’Adamo Personalized Nutrition website makes these science-based books and guides available for purchase in its educational support section.

Live Right 4 Your Type,” published in 2000, further delves into the importance of not only blood type but secretor or a non-secretor status – the term used to describe whether a person’s blood type antigen is present in body fluids like saliva. While applying science to everyday life, the book shares even more detailed lists of beneficial foods, neutral foods, and foods to avoid based on blood type and secretor status. It also recommends supplements and explains how blood type relates to other aspects of health like exercise, sleep, and stress.

Over the last two decades, Dr. D’Adamo has published more than 46 books, and they are available at 4YourType.com.

Dr. D’Adamo’s publications include food, beverage and supplement lists for each blood type along with personalized cookbooks that make it easy to put the dietary recommendations into practice. Newcomers learn it isn’t necessary to strictly follow the diet: the goal is 80% compliance with your blood type’s food lists, and making changes gradually over time.

Scientific studies also reveal that, based on blood type, some people are more susceptible to certain diseases. Dr. D’Adamo believes that eating for your blood type can improve your resistance to both serious and everyday ailments. D’Adamo Personalized Nutrition provides access to condition-specific guides for fighting serious health problems, like diabetes and cardiovascular disease, as well as arthritis, allergies, and fatigue.

Dr. D’Adamo’s goal is to spread the news that changing your eating habits to accommodate your genetics can make it possible to live a healthier life and lower your risk of disease based on blood type predisposition.

Targeted Formulas and Vitamins to Address Individualized Needs

In addition to detailed dietary guidelines, 4YourType.com sells Dr. D’Adamo’s signature health supplements and formulas, all which account for the individual’s biological makeup. Many of the formulas are designed to work with all four blood types, while others are designed specifically for Type A, B, AB, or O.

Visitors to the site will find typical supplements, such as Vitamin D, as well as blends like Tranquility Base, which provides a natural boost to mental and physical relaxation. Other formulas are designed to improve digestion, increase energy, enhance memory, and help with weight management.

And while the dietary guides and supplements are the core of a solid nutritional plan, 4YourType.com goes further in applying total health science and technology to keep its followers and customers fully engaged in a blood-type conscience lifestyle.

A Well-Rounded Product Line from Skin Care to Digital Media

For those interested in starting the blood type diet, the first step is identifying your blood type; it’s also useful to know other genotype characteristics. And D’Adamo Personalized Nutrition helps people get started by providing solutions for gathering this information with self-directed tests and kits.

Just as certain food molecules wreak havoc with digestion and other aspects of health as they interact with human biology, Dr. D’Adamo’s research shows that particles called AGE molecules — or complex sugar molecules — are primarily responsible for the skin damage that comes with the aging process. Having studied the natural herbs and extracts that combat these harmful sugar molecules and preserve the youthfulness of skin, Dr. D’Adamo formulated his line of skin care products known as Genoma Skin Care, available for purchase from D’Adamo Personalized Nutrition.

Through the Blood Type Diet app, available on Android and iOS, users can view lists of foods approved for their blood type.

Besides his work in glycobiology, Dr. D’Adamo has developed numerous software tools to enable his clients and customers to more easily engage with the blood type diet. One of the most practical tools for people who are always on-the-go is D’Adamo Personalized Nutrition’s blood type diet mobile app — compatible with Android and iOS. The app includes approved food lists for each blood type, tips for eating out, shopping, and meal planning tools so busy people stay on track with their eating plans.

From A Groundbreaking Idea to a Successful Online Health Brand

In 1996, Dr. D’Adamo’s bestselling book “Eat Right 4 Your Type” made him the face of a modern lifestyle brand. What started as his father’s hunch became the target of his research and life’s purpose: improving health by identifying and following the eating plan that best fit a biological profile.

Unlike many short-lived dieting fads, Dr. D’Adamo’s continued research, books, and engagement with the blood type diet community now 7 million strong through D’Adamo Personalized Nutrition has kept the movement growing.

More than a marketplace for Dr. D’Adamo’s products and resources, D’Adamo Personalized Nutrition has become a health and wellness brand that builds and sustains its community through education, direct support, and practical tools that help people succeed at living a blood type-conscious diet and lifestyle.
