Who We Are:

The Nutrition Coalition (TNC) is a 501(c)(3) non-profit, non-partisan educational organization, founded in 2015, with the primary goal of ensuring that U.S. nutrition policy is based on rigorous scientific evidence. We promote the importance of adopting a state-of-the-art scientific process for ensuring evidence-based nutrition policy.  

TNC is actively building a broad and diverse coalition of scientists, health-care practitioners, researchers, policy makers, and concerned citizens to fight nutrition-related chronic diseases in America through rigorous science, education, and effective communication. We invite you to join us. Together, we can change the Dietary Guidelines for Americans, improve public health, and reduce related medical costs for generations to come.


Our vision is a healthier America with significant reductions in obesity and other nutrition-related diseases, including Type 2 diabetes, heart disease, fatty liver disease, and hypertension, among others. Better health outcomes, individually and collectively, will reduce our staggering health care costs as well as improve both the productivity and quality of life for millions of Americans.


Our mission is to ensure the federal government’s nutrition advice is based on comprehensive, systematic reviews of the most rigorous nutrition science available and to encourage additional research where that science is lacking.


TNC’s goal is to promote and enact national nutrition policy that is based on the best possible scientific evidence, in order to improve the public health. Our top priority is reform of the U.S. Dietary Guidelines for Americans (DGA). Once considered the “gold standard” of nutrition evidence by medical and health organizations worldwide, confidence in the DGA has eroded in recent years, due to the inclusion of recommendations that are supported by flawed or weak science.

To restore the credibility of the DGA, this policy must be evidence-based, grounded in rigorous science, and evaluated according to state-of-the-art systematic reviews.

Wherever nutrition policy clearly deviates from the best and most current scientific research, TNC will seek to correct that divergence. Wherever evidence is lacking, the Coalition will advocate for new and reallocated government funds for additional research in order to close the information gap and facilitate science-based advice.

And until conclusive data is available, TNC believes that nutrition policy should simply inform rather than advise, according to the principle of “first, do no harm.”

What we are not:

TNC does not promote any particular diet. However, TNC does challenge specific DGA recommendations that our scientific council has concluded are based on contradictory or weak evidence. TNC also brings to light evidence that has been overlooked or ignored.

What we have accomplished so far:

In 2015, TNC helped encourage the U.S. Congress to mandate that the National Academy of Science, Engineering and Medicine (NASEM) conduct the first-ever outside peer review of the DGA process. In a report published in September 2017, NASEM found that this process falls short of meeting the “best practices for conducting systematic reviews,” and that the “methodological approaches and scientific rigor for evaluating the scientific evidence” need to “be strengthened.” The report states: “To develop a trustworthy DGAs, the process needs to be redesigned.”
