Researcher Promotes Maple Syrup Health Benefits Amid Funding Concerns
For over a decade, biomedical researcher Navindra Seeram has lauded maple syrup as a potentially beneficial food, describing it as a “hero ingredient” and “champion food” with far-reaching health benefits. However, his enthusiastic endorsement occurs alongside substantial industry funding, raising questions about the claims made regarding maple syrup’s purported health advantages.
Academic Research and Industry Ties
Dr. Seeram, currently the dean of the School of Pharmacy at the University of New England, has published numerous studies, exceeding three dozen, extolling the virtues of maple. A significant portion of this research has been financially supported by the Canadian maple syrup industry, along with the Canadian and American governments. Simultaneously, Dr. Seeram has also actively engaged in promoting maple syrup products.
Dual Role: Scientist and Promoter
In grant applications, Dr. Seeram has asserted his unique position as “the world’s leading researcher on maple health benefits” with the scientific standing and credibility to boost maple product sales. Emails obtained through public records requests reveal assurances to Canadian industry leaders of his unwavering support for Quebec maple.
Scrutiny of Health Claims
An examination by The Examination and The New York Times, reviewing 15 years of his studies and public pronouncements, suggests Dr. Seeram has blurred the lines between scientific investigation and promotion. This review indicates a potential distortion of his findings’ practical implications and an exaggeration of health benefits. In videos and press releases, he has implied that maple syrup consumption might help prevent diseases such as cancer, Alzheimer’s, and diabetes. Other scientists have expressed concerns to The Examination and The Times, suggesting that Dr. Seeram has overstated his laboratory findings and made potentially misleading claims.
Funding and Potential Conflicts
The prevalence of industry funding in nutrition research is noteworthy, potentially amplified by recent reductions in government funding for scientific endeavors. Dr. Seeram’s work highlights the potential pitfalls of intertwining scientific research with commercial interests, particularly when disseminating information that can influence consumer habits and public health perceptions.

Promotional Activities and Social Media
During his tenure at the University of Rhode Island, Dr. Seeram oversaw projects supported by $2.6 million in U.S. government funding, including a grant explicitly aimed at increasing maple syrup sales. This promotional effort resulted in social media posts proclaiming, “Maple Syrup’s Benefits: Anti-Cancer, Anti-Oxidant, Anti-Inflammatory.”
YouTube Video and Disease Prevention
In a 2019 YouTube video, Dr. Seeram suggested that nutrients in maple syrup could “potentially together prevent and/or delay the onset” of conditions including “cardiovascular disease, metabolic syndrome, diseases of the brain and so on.”
Lab Findings vs. Real-World Consumption
However, his studies primarily demonstrate that maple syrup contains limited quantities of polyphenols, plant-based compounds generally recognized for their beneficial properties. To assess their effects, he tested highly concentrated maple extracts in controlled laboratory environments – distinct from human consumption of commercial maple syrup.
Researcher’s Defense
Dr. Seeram stated to The Examination that he believes in the efficacy of natural medicines, rooted in his South American upbringing. He defended his characterization of his findings, asserting, “No one can go back to direct-quote from me to say, ‘It’s going to cure cancer, it’s going to cure diabetes.’”
Concerns Over Broad Health Claims
His conclusions frequently incorporate cautious phrasing, such as maple syrup “may” or “could” have meaningful health effects, or include disclaimers advocating for further investigation. Nevertheless, several researchers contend that these caveats are insufficient to counter broad health claims, and that Dr. Seeram has extrapolated excessively from laboratory findings to practical applications.
Expert Opinions
“They are framing it in a far more positive light than they should,” stated Christopher Gardner, a nutrition researcher at Stanford.
Response to Scrutiny
In an interview, Dr. Seeram attributed the heightened scrutiny of his work to a former colleague at the University of Rhode Island. A university representative indicated that the institution had investigated and found no research misconduct.
Simplifying the Message for Consumers
At a maple industry conference in October, Dr. Seeram described his work as aimed at making “it simple for Mom to understand” the benefits of syrup.
Marketing Strategy
“We have to convince the consumer that this sugar is good for you,” he conveyed to maple farmers, outlining a strategy to reach the public: publication of his studies in peer-reviewed journals, leading to marketing and media coverage, and ultimately, encouraging consumer purchases.
Industry Funding Details
The Quebec Maple Syrup Producers, a major industry association, has long been a funder of Dr. Seeram’s work. Together with the Canadian government, the association has reportedly provided at least $2.8 million for his research, according to a 2019 grant application. The association challenged this figure without providing specific details, a stance mirrored by Dr. Seeram.
Consulting and Public Relations Roles
Emails and invoices reveal that the association has also engaged Dr. Seeram for consulting services and “PR activities” for a decade or more. In 2023, his fees for these services totaled $37,000, as indicated in emails.
Commitment to Industry Promotion
In a 2018 email exchange with association officials, Dr. Seeram affirmed his commitment to “always work to find ways to promote maple products from Quebec.”
Pomegranate Research Precedent
The maple association’s outreach to Dr. Seeram in 2009 followed the example of POM Wonderful, whose promotion of pomegranate juice during the 2000s craze was fueled by research he had funded and utilized. (The Federal Trade Commission later issued a cease-and-desist order against POM Wonderful, citing misleading or false claims based, in part, on a study co-authored by Dr. Seeram.)
Shift to Maple Research
Although Dr. Seeram had not previously focused on maple, he told The Examination that his recent move to the Northeast, a region significant for maple production, sparked his interest. Subsequently, he announced the discovery of numerous polyphenols in maple syrup, including Quebecol, a compound named by his team.
Broad Health Applications Suggested
Based on laboratory analyses of concentrated compounds, he began suggesting that maple syrup possessed extensive applications for human health.
“Champion Food” Claims
“Maple syrup is becoming a champion food,” he declared in a 2011 press release. “Several of these compounds possess antioxidant and anti-inflammatory properties, which have been shown to fight cancer, diabetes and bacterial illnesses.”
Expert Skepticism
However, experts caution that the low concentrations of these compounds in syrup are unlikely to significantly improve health. Dr. Seeram has acknowledged that consuming gallons of maple syrup would be necessary to obtain the nutritional equivalent of the extracts used in his research. He often clarifies that he is not advocating for increased sugar consumption but rather suggesting maple syrup as a preferable alternative.
USDA Funding and Mouse Study
The U.S. Department of Agriculture (USDA), another significant funder, awarded over $2.6 million to Dr. Seeram’s research. This included nearly $500,000 in 2017 to investigate whether maple syrup extract could enhance the health of obese mice. Study findings, referenced on a government website and in a student dissertation, indicated no health improvement and, in some instances, worsened conditions in the mice. These results were not published in an academic journal. Dr. Seeram did not respond to inquiries regarding this study.
Promotional Campaign Website
In 2018, the USDA awarded $500,000 to a group led by Dr. Seeram for a promotional campaign featuring maple research on a University of Rhode Island website. Dr. Seeram’s grant application stated his responsibility for translating the science into “lay-friendly terminology.”
Misleading Website Content
The website, under his team’s oversight, described maple syrup as “immensely healthy for you.” Despite disclaimers indicating the need for further research, it made potentially misleading statements, linking reduced-sugar maple extract studies to the consumption of maple syrup. One example posed the question: “Did you ever think that you could fight high blood sugar with some things as sugary and delicious as maple syrup?”
Cancer Prevention Speculation
The website further suggested that the Quebecol compound could become a “potential cancer prevention drug,” noting its “remarkably similar” structure to the breast cancer drug Tamoxifen – a comparison Dr. Seeram has also used in presentations.
Expert Disagreement on Cancer Claims
Cancer researchers interviewed found this comparison to be misleading. Geoffrey Greene of the University of Chicago likened it to expecting a concert violinist’s brother to also be a concert violinist simply due to physical resemblance.
Justification for Promotion
When questioned about using his research to promote maple products, Dr. Seeram stated he was merely fulfilling the terms of the government grant. A USDA spokeswoman deferred responsibility for the website’s claims to the University of Rhode Island.
Website Removal
The university declined to comment on the research. Following inquiries from reporters, the website was deactivated as part of a broader initiative to remove inactive pages, according to the university.
Alzheimer’s Study and Worms
One of Dr. Seeram’s studies examined Alzheimer’s-related effects by administering maple syrup extract to genetically modified worms. While some worms showed improvement, overall, they fared worse. However, the summary in Dr. Seeram’s 2016 Neurochemical Research paper omitted the negative results, stating the syrup extract “showed protective effects.”
Media Headlines and Nuance
An industry association press release claimed maple syrup extract prolonged the worms’ lives, despite the averaged shorter lifespan, with a disclaimer for further research. This nuance was lost in media headlines across various countries, proclaiming maple syrup’s potential to protect against Alzheimer’s.
Criticism of Alzheimer’s Study
Christopher Link of the University of Colorado Boulder, a pioneer in Alzheimer’s research using worms, critiqued the study, citing missing details such as the number of worms and replication of the experiment. Dr. Link noted that many plant extracts show positive results in similar experiments, but real-world applications are not guaranteed.
Industry Association Response
Julie Barbeau of the maple association stated their adherence to strict ethics and “no influence whatsoever” on funded research projects.
Disclosure Issues
At least a dozen of Dr. Seeram’s papers, reportedly funded by the maple association, did not disclose this funding relationship. His paid consulting role and a Canadian maple extract patent listing him and Ms. Barbeau as co-inventors were also undisclosed in his papers.
Publisher Requirements
Six publishers of Dr. Seeram’s work confirmed their requirements for authors to declare potential conflicts of interest. Dr. Seeram did not respond to inquiries about his disclosures.
Defense of Industry Funding and Patents
Dr. Seeram has publicly acknowledged financial support from the maple association. In previous interviews, he defended industry funding as essential due to limited alternative research funding. He also defended his patents, stating, “The driver here is not for me to get rich.” The maple association cited protecting its intellectual property as the reason for the patents.
Human Clinical Trial
Last year, the association promoted a newly funded study as the “first human clinical trial” of maple syrup.
Study Results and Expert Review
Participants substituted a small amount of dietary sugar with maple syrup. Researchers told Newsweek the results, published in The Journal of Nutrition, indicated that maple syrup improved blood sugar, blood pressure, and fat measures, potentially reducing diabetes and cardiovascular disease risks. Dr. Seeram, while not an author, viewed the results as validating his work.
Overstated Conclusions
However, three independent experts reviewing the research deemed the conclusions overstated, emphasizing minor positive results among numerous measures. They indicated the study showed no significant difference between maple syrup and refined sugar.
Expert Critique
“They took it too far,” commented Kimber Stanhope, a nutritional biologist at the University of California, Davis.
Researcher’s Response
Lead researcher André Marette of Laval University acknowledged that the differences between maple syrup and refined sugar were “modest” but considered them meaningful. Through a public relations firm representing the industry association, he stated, “We were careful to state that the clinical relevance of the work will need to be further substantiated.”
Media Coverage and Public Perception
In the meantime, the findings have reached the public. A women’s magazine headline exclaimed, “Sweet! Maple Syrup in Coffee Could Help You Lose Weight.”
