  • Eaters Deserve More Complete Information About Nutrition and Health Impacts on Food Labels  

    Multiple lines of evidence point to consumer food choices as major contributors to diet-related disease, and poor health and fitness. In a peer-reviewed journal article published today, authors Chuck Benbrook and Robin Mesnage cite studies indicating that “Some 90% of the estimated USD 4.3 trillion in annual health care costs in the US is triggered or made worse by poor food quality and diet-related disease.” Benbrook is the founder and former executive director of the Heartland Health Research Alliance (HHRA). The authors recommend novel metrics on both the nutrient density of food, and how to more accurately and usefully characterize the degree of food processing and its impacts on public health. The article is open access in the journal Foods and entitled “Enhanced Labeling to Promote Consumption of Nutrient Dense Foods and Healthier Diets.” The core nutrient density metric is a ratio: the percent of daily nutrient needs satisfied by a serving of food relative to the percent of a 2000 calorie daily diet taken up by the serving of food. This single metric is unmatched in comprehensively reflecting the nutritional quality of food. A graphic option to convey the metric on packaging is presented in Figure 3 in the new paper: A novel graphic is presented in Figure 5 to which integrates both the nutrient density and food processing metrics and graphics in a single graphic, shown below. The impacts of ultra-processed food (UPF) on public health outcomes is among the hottest topics in nutrition, medical, and public health journals, and media coverage on food quality and health outcomes. At the request of the journal, the authors developed a video abstract that explains the paper’s goals, methods, and key findings and recommendations. The authors conclude their paper with these observations: Transparent and accurate food product-specific ingredient and nutrient composition data should determine the content of nutrition health labeling. Efforts to soften the message should be resisted in light of the overwhelming need for new food labels that help bring about substantial improvements in food nutritional quality and dietary choices. Benbrook and Mesnage’s paper builds on public comments HHRA submitted in response to the US Food and Drug Administration (FDA) proposed rule in 2023 to update the definition of the term “healthy” on food labels. The proposed role would require foods labeled “healthy” to contain minimum amounts of foods recommended by USDA’s Dietary Guidelines, and to limit saturated fat, sodium, added sugar and other less healthy nutrients. Entitled “Food Labeling: Nutrient Content Claims; Definition of Term `Healthy’”, the comments recommended new  nutrition/health messaging on the front of food packaging. Co-authors of comments included the chair of HHRA’s Policy Advisory committee Dr. Kathleen Merrigan, HHRA science advisors, and other experts working on how changes in farming systems and technology can increase the nutritional quality of food: Dr. Hannah Flower, Dr. Donald R. Davis, Dr. David Montgomery and Anne Biklé. In the comments, the authors introduced “NuCal” as a name for their new system. Resources HHRA February 2023 comments to the FDA.

  • HHRA Weighs in on Key Pesticide Issues Under Review by the National Organic Standards Board

    HHRA and ORG-Tracker, represented by Dr. Chuck Benbrook and Dr. Brian Baker, submitted comments to the Agricultural Marketing Service at the USDA in advance of the National Organic Standards Board (NOSB) meeting in Portland, Oregon, from October 22nd to 24th, 2024. Drs. Benbrook and Baker will both attend the conference and deliver public comments. ORG-Tracker is a project carried out by HHRA. It aggregates pesticide residue data from inspections of organic farms carried out by certifiers. The tables generated by ORG-Tracker utilize the results of certifier testing to compare residue frequency and risk levels to food produced on conventional farms. The team is working to more effectively highlight gaps and challenges faced by certification agencies to answer questions like What crops should we be testing, and where? Is a pesticide residue found in an organic sample likely caused by accident, pesticide drift, or an intentional and illegal application? How can we modify organic programs to better mitigate risk? The comments delivered to the USDA discuss risk-based certification, pesticide residue testing, and policies impacting the incorporation of so-called inert ingredients in the biopesticides approved for use on organic farms. They argue for a more rigorous, comprehensive, and health-focused approach to risk oversight. Regarding residue testing, they advocate for more expansive and effective data aggregation to inform consumers and the organics community. Finally, for inert ingredients, they recommend further review of current policy, including increased transparency of ingredients in pesticide products. Thank you to Drs. Benbrook and Baker for your advocacy and hard work!   The three sets of comments are posted on HHRA’s website as part of our policy program: Comments to the NOSB on the Risk-Based Certification Discussion Document Under Consideration During the October 2024 Meeting in Portland, Oregon Written Comments on the NOSB Discussion Document “Residue Testing for the Global Supply Chain” Comments on the Inert Ingredients in Organic Pesticide Products Proposal dated August 13, 2024   Drs.

  • Heartland Study Enrolls 1,000th Mother-Infant Pair

    July 19, 2024 – In June of this year, the Heartland Study achieved a major milestone, enrolling its 1,000th mother-infant pair. Enrollment is now at 50% of goal. The objective of the Study is to help fill major gaps in our understanding of the impacts of herbicides on maternal and infant health. Currently in Phase 1, the Study is focused on evaluating associations between herbicide concentrations in body fluids and tissue samples from pregnant women and infants, and pregnancy/childbirth outcomes. Phase 2 is designed to evaluate potential associations between herbicide biomarkers and early childhood neurological development. Much appreciation for the mothers enrolled, and the entire Heartland Study Team including scientists, support staff and clinicians for this tremendous achievement, and for our funders to making this work possible.

The investment required to conduct this study exceeds $1 million each year. You can support this important work by making a donation here.

HHRA Paper Quantifies Impact of Organic Farming on Pesticide Use and Dietary Risks

A new HHRA paper highlights the need to convert cropland growing fruits and vegetables to organic in order to reduce consumer's dietary risk from pesticide residues.

A new HHRA paper published in the peer-reviewed journal Agronomy reports significant impacts of organic farming systems on pesticide use and the risks stemming from pesticide residues on food.

“Organic Farming Lessens Reliance on Pesticides and Promotes Public Health by Lowering Dietary Risks” was co-authored by HHRA Executive Director Chuck Benbrook, and research partners Susan Kegley, and Brian Baker. Published on June 22nd, this is an open-access, free to download paper accessible via our bibliography.

Lead author Dr. Benbrook has published several papers over three decades comparing pesticide use and risks in organic versus conventional foods but states that “This paper contains the most rigorous, data-driven comparison of pesticide use and dietary risks on organic fields producing a give crop compared to nearby conventionally managed fields. Our findings are encouraging.”

The 36-page paper provides detailed comparisons of pesticide use on organic farms compared to nearby conventional farms growing the same crop. The team developed a methodology to extract the data needed to make such comparisons from the detailed Pesticide Use Reports collected and made available by the California Department of Food and Agriculture.

The EPA has approved just 91 active ingredients for use as pesticides on organic farms (see Table S.1 in the paper’s supplemental tables for the full list). Many of these are common ingredients found in many households, such as isopropyl alcohol, soap, vinegar, and clove oil. Meanwhile there are over 1,200 pesticide active ingredients approved for use on conventional farms.

Tables in the paper compare pesticide use on nearby organic and conventional carrot, grape, and tomato fields in selected California counties. “The techniques we developed to do this work made it possible to use the California pesticide use data to easily find organically managed fields and compare pesticide use between organic and conventional crops in the same county,” according to co-author Dr. Susan Kegley.

In a many cases in California, the same grower manages fields producing the same crop under these two management systems. The team developed methods to identify such fields and compare the pesticides used on each, as shown in the interactive graphic below.

The detailed comparisons of the residues and risk levels in organic and conventional foods were done using HHRA’s Dietary Risk Index (DRI) system. The data sources and methodologies embedded in that system are described in a 2020 paper in the journal Environmental Health.

You can access a series of interactive tables reporting DRI system results comparing residues and risks in organic and conventional foods on Hygeia Analytics. These tables draw on pesticide residue data from the USDA and pesticide toxicity data from the EPA.

A key conclusion of the team’s analysis is that by converting the 1.2% of US cropland growing fruits and vegetables to organic production, the nation’s farmers could dramatically reduce pesticide dietary exposures and risk.

“We have empirical evidence to support what organic farmers have known all along. It is possible to grow high quality crops with biological and cultural practices, instead of relying primarily on toxic pesticides,” says co-author Dr. Brian Baker. Doing so will lead to substantial public health gains, especially for pregnant women, infants, and children, and those people applying pesticides and exposed to them occupationally in or near farm fields.
