Leading Experts Propose a New Metric For Protein Quality
An Update to an Outdated and Harmful Protein Quality Definition

- True Health Initiative has convened top nutrition experts to define a new, modernized protein quality metric that can be applied to our food system.
- The paper will be published in the high-impact, peer-reviewed journal, Advances in Nutrition on May 8th and is co-authored by David Jenkins, PhD, MD, University of
Toronto; Kate Geagan, MS, RD; Kimberly N. Doughty, MPH, PhD, Yale-Griffin Prevention Research Center, Christopher D. Gardner, PhD, Stanford University and
David L. Katz, MD, MPH, Yale-Griffin Prevention Research Center.
- Quality protein foods should be those that have a net positive effect on both peoples’ and planetary health.
- The current definition of protein quality is outdated, incorrect and harmful to public health.

Derby, CT, May 8th, 2019: In the comprehensive new paper, "The Public Health Case for Modernizing the Definition of Protein Quality” published in Advances in Nutrition , True Health
Initiative, with leading experts, redefines protein quality based on current scientific evidence. The researchers then adapted this new definition into a metric that can be applied to national
food regulatory and labeling systems. The paper outlines why our current definition of protein quality is obsolete, inaccurate, and harmful to both human and planetary health.
Consumers depend on accurate nutrition information to make food choices that benefit their health and longevity. The current definition of protein quality does not account for the net health
effect of protein foods and can promote foods that are in direct opposition to the current Dietary Guidelines for Americans, human health and environmental sustainability. 

The True Health Initiative puts forth a new definition of protein quality that includes:
●     The concentration of protein and individual amino acids in the food.
●     Assessment of the evidence of health outcomes associated with consumption of the
●     Assessment of potential environmental impacts of producing the food.

The application of this new metric has the potential to improve public health outcomes, cut healthcare costs and accelerate the transition to a more sustainable food system by increasing
public perception of healthy, affordable and widely available protein sources. The paper’s authors set forth to meet the urgent needs of public health. “There really is a perfect
storm in modern culture driving misconceptions about protein. There is the idea that the more the better; there is the idea that you need to eat 'complete' protein from animal foods like meat;
and there is the idea that foods with the highest protein content are the highest quality food sources of protein. None of these is true.”- David L. Katz. MD, MPH.

What is true is that in the United States and in other developed economies, protein deficiency is not a prevailing health concern; far greater in the 21st century is the epidemic of costly, chronic
illness that is directly preventable by changes in diet and lifestyle. Cardiovascular disease, type 2 diabetes and cancer have all been linked to unhealthy diets in general and excessive intake of
red and processed meats in particular. In direct contrast, plant forward diets and diets that include: fish, nuts and seeds, have been linked to favorable health outcomes, reduced all-cause
mortality and reduced cardiovascular mortality.

“The original goal was to promote growth in a vertical direction in the young (height) but if applied to older people, the only direction to grow is laterally (horizontal growth equals =
obesity). The dietary metrics used now must encourage a lifestyle of health. That is why a new approach to defining protein quality is urgently required that recognizes the value of plant
proteins and will allow people to eat for their own health and the health of the environment.”- David Jenkins MD, PhD

“The current criteria for determining protein quality are obsolete, particularly for the large proportion of the planet where chronic diseases have displaced infectious diseases as the more
prevalent public health concern. The proposed redefinition addresses an urgent need to better align human health with the health of the environment and the sustainable future of food.”-
Christopher Gardner, PhD.

“I think it’s pretty clear that we have the wrong approach to defining protein quality when processed meats and frozen dinners that are laden with sodium and saturated fat can be
labeled ‘good sources of protein.’ That these claims can be made to help sell foods known to be associated with chronic disease risk to consumers who already consume more than enough
protein is perverse. The update we have proposed is just common sense.”- Kimberly N. Doughty, MPH, PhD

“This “protein fix” is long overdue: consumers deserve an updated definition that better reflects the actual impact of dietary protein sources on public health, aligns with the latest scientific
evidence, and helps eaters obsessed with protein make the best choices to match their budget and their health goals. It’s rare to find a single switch that holds this kind of potential to help
solve some of our most urgent public health crises- but "protein quality" is one of them.”- Kate Geagan, MS RD.

True Health Initiative is a global coalition of world-renowned experts, converging to fight fake facts or cherry picked data, challenging false narratives and working to create a world free of
preventable disease while conjointly safeguarding planetary health. Studies have shown that nutrient content claims can increase consumers’ perception of a food’s overall healthfulness and
are a desirable factor in food purchasing. Updating this metric to reflect the latest science gives consumers necessary, evidence-based information, enabling the public to make choices that
improve health.

This new protein definition would update protein content claims to 21st century science-and help meet the challenges of feeding 10 billion people on a healthy planet in 2050.
True Health Initiative’s, “The Public Health Case for Modernizing the Definition of Protein Quality" is a step in the global movement towards a healthier and more sustainable future.
