Nutrition Response Testing is a treatment modality for resolving chronic health issues. According to the founder's website, it's a "non-invasive system of analyzing the body in order to determine the underlying causes of ill health."

This description doesn't differentiate the practice at all from conventional medical care in our opinion.

In this article we’ll review Nutrition Response Testing in more detail, explain why we don't recommend it, and suggest some alternatives with more research backing.

What is Nutrition Response Testing?

Nutrition Response Testing, also called applied kinesiology, has become popular in the alternative health provider circles as well as “natural” chiropractic offices. We put natural in quotes in this context because it’s an unregulated and clinically meaningless term.

The process involves a “health practitioner” who’s usually not a Medical Doctor applying pressure to various parts of the body and assessing “weaknesses." As a logical reader can already deduce, this is a very subjective and unscientific process.

The Nutrition Response Testing “specialist” then prescribes a diet to the patient, often with supplements and food concentrates, which is thought to improve their condition and resolve their chronic health issues.

The Nutrition Response Testing website referenced previously states the following without any research citation or proof: "Each area that gives a response represents a specific organ, tissue, or function, and indicates the effect that energy, or the lack of energy, is having on the body."

Why We Don't Recommend It

We can't locate a single medical study proving or even suggesting that this practice is effective. A search for "Nutrition Response Testing" in PubMed, which is one of the largest free medical databases in the U.S., returns zero results. Even "homeopathy" returns over 6,000 results.

There is also no logical reason that pressing on people’s skin would confer knowledge of their nutritional deficiencies. It's impossible to determine nutritional state from outward appearance or touch outside of rare medical conditions such as jaundice which can turn skin yellow.

The most popular websites describing their Nutrition Response Testing practice, which we won’t link to because we don’t wish to support their practice, don’t explain how this process works biologically. We strongly believe that it's unethical to profit from people desperate for answers to their chronic health problems, without any research-based proof of efficacy.

Alternatives to Nutrition Response Testing

Dealing with a chronic health condition can be frustrating, and we empathize with patients going to such lengths to try and treat their condition(s). In many cases, conventional medicine isn’t structured to solve complex, multifactorial problems, moreso to treat symptoms, but there are still objectively superior solutions to Nutrition Response Testing in our opinion.

Nutritional deficiencies, which Nutrition Response Testing seeks to resolve, are easily detectable with standard blood tests ordered at a doctor's office. Even a standard blood panel tests for many vitamins and minerals, and there are more advanced blood panels like intracellular nutrient testing which can uncover deficiencies to a more accurate degree.

As an example, magnesium is a mineral that’s incredibly important to human health, but a standard blood panel only tests for magnesium levels in the blood. This is an outdated and non-ideal way to test for magnesium because most of this mineral is stored in tissue and bone (greater than 99% according to medical research). An intracellular nutrient test could uncover low magnesium levels that a standard blood panel may not.

We recommend that patients with chronic health issues request thorough blood work from their doctor, and even consider paying out-of-pocket for more advanced blood work when financially feasible. To solve a complex health problem you need as much information about your current health state as possible, and that information can be attained through legitimate medical testing.

Registered Dietitians

Another option that patients should consider when attempting to resolve nutritional deficiencies is to work with a Registered Dietitian (RD). The Academy of Nutrition and Dietetics maintains a database of RDs in the U.S. Patients can enter their ZIP code and find an RD in their area.

RDs are trained to work with patients and create an individual dietary strategy that will improve their health. They can work with a patient's doctor to order and interpret lab tests related to nutritional status.

We believe that partnering with an RD would be a greatly superior solution to working with a "Nutrition Response Testing expert," and RDs are covered or subsidized by health insurance in many cases.

Conclusion

We would recommend against using Nutrition Response Testing as a treatment methodology for any health conditions. We cannot identify any medical research suggesting it to be effective.

Patients seeking to resolve chronic health issues would be best suited to undergo lab testing ordered by a legitimate Medical Doctor, and try to find the root cause of their issue. It may also benefit patients with perceived nutritional deficiencies to work with an RD.
