A Skeptical Look at the
Institute for Integrative Nutrition
Stephen Barrett, M.D.
The Institute for Integrative Nutrition (IIN), headquartered in New York City, refers to itself as "the world's largest nutrition school." Founded in 1992, it is said to have an annual enrollment of more than 1,600 students [1]. Its primary offering is a part-time, 8-month course said to enable graduates to practice as "health counselors." I have serious doubts about the validity of its teachings.
Background Information
IIN's founder, director, and primary teacher is Joshua Rosenthal. The biographical sketch in his book Integrative Nutrition states:
He is a highly trained leader who has a Masters of Science degree in Education, specializing in counseling. With more than 25 years of experience in the fields of whole foods, personal coaching, curriculum development, teaching, and nutritional counseling, he is a highly sensitive healer whose enthusiasm shines through in all his work. His simple approach allows people to quickly and successfully reach new levels of health and happiness [2:341].
A 2002 interview in Satya Magazine indicates that IIN was originally named Gulliver's and that before founding it, Rosenthal had operated a "natural food" store in Canada [3].
IIN's primary course extends over an 8-month period. Its tuition of $8,950 is said to cover:
Weekend class instruction, lectures given by world-class speakers, a personalized website, one-on-one health counseling, access to our Online Education Forums, Warm Up classes, business cards, handouts, personalized brochures, a comprehensive CD-ROM set to help you organize your practice, books and other materials, an embossed diploma and a party for all students to help beat the winter blues with healthy organic food.
The IIN program is open to anyone who is willing to attend and pay tuition. No formal training or nutrition-related knowledge is required. To graduate, students must attend at least eight out of ten weekend seminars, complete six "health history consultations," enroll two clients in a 6-month health counseling program, pass three multiple-choice tests, and attend at least five "counseling" sessions [4]. The counselor—typically a recent graduate— provides advice about the student's experience with clients and "models" the student for the six-month program. (I assume that this means the student goes through the program with the counselor as advisor.) Students also get advice and share ideas and experiences with fellow students through online forums on the IIN Web site.
Rosenthal's Integrative Nutrition Food Pyramid is adapted from the United States Department of Agriculture Food Pyramid. It includes extra water and a "primary food circle" that symbolizes "healthy relationships, regular physical activity, a fulfilling career, and spiritual practice, all of which are said to "feed our bodies and satisfy our hunger for living."
Each of IIN's weekend seminars includes several guest speakers. The 2007-2008 IIN catalog lists 33 of them, most of whom promote offbeat ideas. Included are Andrew Weil, M.D., Depak Chopra, M.D., and macrobiotic guru Michio Kushi, M.D.
IIN graduates receive a "health counselor" certificate and are automatically eligible for "board certification" by the American Association of Drugless Practitioners (AADP). In 2007, for an additional $495, they could also receive a "Certificate in Health Counseling" and 15.5 Continuing Education Units from the Center for Educational Outreach and Innovation at Columbia University's Teachers College, which "partnered" with IIN that year [4]. IIN itself is not accredited by an agency recognized by the U.S. Office of Education [5]. Columbia terminated its affiliation early in 2008.
AADP "certification" has no scientific recognition and is certainly not a sign of professional competence. Membership, which automatically includes "certification," is available to "any doctor or practitioner that practices "drugless" therapies or methodologies." [6] The basic requirement is payment of $285 and graduation from one of 34 AADP-approved schools, all of which have unscientific teachings. Many IIN graduates describe themselves on the Internet as "board-certified" or a "certified holistic health counselor," and a few even describe themselves as having certification from Columbia University or from Columbia University Teacher's College.
What Is "Integrated"?
IIN's program focuses on foods and eating choices but contains little about the sciences of biochemistry or physiology on which dietary strategies should be based. The goal appears to be to enable students to find what dietary and activity strategies work best for them and then do the same for clients. The catalog states that IIN teaches more than 100 different dietary therapies and "analyzes the pros and cons of them all." The Dietary Theory chapter of Rosenthal's book discusses about a dozen of these approaches. These include:
- Ayurveda, which bases food choices on alleged body types and the season of the year.
- Blood Type Diet, which claims that optimal diet depends on blood types.
- Five-element theory, which recommends foods based on the ancient Chinese notion that we are surrounded by "energy fields" (wood, fire, earth, metal, and water) that must be balanced to promote "self-harmony."
- Macrobiotics, which advocates foods based on "balancing yin and yang."
These strategies —and most of the rest—not only clash with science but also with each other. But Rosenthal doesn't seem bothered by this because he asserts that "all diet programs contain elements of truth." [2:76] To assist the "integrative process," his book provides a mishmash of facts, opinions, incorrect pronouncements, practical advice, and nonsense. The nonsense includes:
- While understanding one's body type is important, it is by no means the core teaching of Ayurveda. In India, Ayurvedic doctors usually . . . . look at a patient's susceptibility to imbalance." [2:84]
- "If you are eating mostly earth foods, it may help to increase wood foods because woods hold down the earth." [2:88]
- "I've seen a great deal of truth in the Blood Type categories. . . . Type O people often have difficulty metabolizing and digesting wheat." [2:101]
- Drinking more water increases yin." [2:187]
The dietary part of Rosenthal's 12-step integrative plan includes drinking more water, and generally eating more grains and vegetables and less meat and dairy products. He advises implementing one step at a time, seeing what effect it has, and retaining what seems to make you feel best. I am skeptical of this approach because how people feel can be extremely variable and is not usually related to food intake.
The Bottom Line
IIN is flooding the marketplace with graduates who market themselves as "board-certified health counselors." Their training is certainly not based on scientific nutrition as emphasized in the degree programs accredited by the Commission on Accreditation for Dietetics Education. That generally takes 4-7 years and includes basic sciences, dietetics, and closely supervised work with many clients. IIN provides almost none of this. It teaches—in effect—to use your own experience to inspire others.
I personally would not trust someone who lacks scientific training to tailor diets based on dietary needs or who relies on IIN's teachings to counsel patients. Nor do I believe that "counseling" two clients is enough to enable students to provide quality advice or to know their limitations. Rosenthal's approach might inspire some people to improve their diet by moving closer to the Dietary Guidelines for Americans. However, they may also absorb misconceptions about diet, health, and disease that will ultimately harm them.
