A rare industry-funded study with unhappy results for the Honey Board funder

The USDA has just done a write up on a study it funded in collaboration with the National Honey Board:  Consumption of Honey, Sucrose, and High-Fructose Corn Syrup Produces Similar Metabolic Effects in Glucose-Tolerant and -Intolerant Individuals.

This was one of the 12 industry-negative studies I posted to my collection of 168 industry-funded studies from March 2015 to March 2016.

 

The USDA article explains:

Controversy exists over whether all sweeteners produce the same metabolic effects in consumers despite the sweeteners’ chemical similarities. A study conducted by U.S. Department of Agriculture (USDA) researchers indicates that consuming lower amounts of added sugars is a more effective approach to health than finding a sugar that is more neutral in terms of its health effects…Volunteers [consuming honey, white cane sugar, or HFCS] did not show any differences in blood sugar levels based on the dietary sugar source. In addition, blood levels of triglyceride, an indicator of blood fat concentrations (a marker for heart disease risk), increased in response to all three sugars tested.

White cane sugar is 50% glucose and 50% fructose, linked together (but quickly separated in the body).  Honey and High Fructose Corn Syrup are glucose and fructose, already separated, but with slightly higher percentages of fructose.  Biochemically, they are not all that different.

So the results of this study, disappointing as they may have been to the Honey Board, were predictable on the basis of basic sugar biochemistry.

Industry-funded study of the week: Honey

A reader, Colleen Wysocki, sent me a note about this study, the basis of a Nutrition and Dietetics SmartBrief e-mailed to members from the Academy of Nutrition and Dietetics to members.

 RD: Enhance yogurt’s probiotic power with honey…A study in the Journal of Nutrition published earlier this year found that clover honey helps probiotics in yogurt survive longer during digestion, particularly benefiting the probiotic Bifidobacterium animalis…honey adds antioxidants and acts as a protective agent for probiotics. Research advises using just one to two tablespoons of clover honey per serving to optimize probiotic survival.

Here’s the study: Alvarado DA, Ibarra-Sánchez LA, Mysonhimer AR, Khan TA, Cao R, Miller MJ, Holscher HD. Honey Varietals Differentially Impact Bifidobacterium animalis ssp. lactis Survivability in Yogurt through Simulated In Vitro Digestion. J Nutr. 2024 Mar;154(3):866-874. doi: 10.1016/j.tjnut.2024.01.010.

Method: This was an in vitro (petri dish) study of the effects of honey on bacterial counts, with and without the addition of “simulated intestinal fluids.”

Results: “Yogurt with 10-20% wt/wt clover honey increased B. animalis survivability after simulated in vitro digestion (≤ ∼4.7 Log CFU/g survival; P < 0.05).”

Conclusion: “Yogurt with added honey improves probiotic survivability during in vitro digestion.”

Funding: “This work was supported partially by the National Honey Board (HDH and MJM).”

Comment: Honey may be delicious, and no wonder; it is 82% sugar, mostly fructose (41%) and glucose (35%) and not all that different biochemically from sucrose (table sugar).  The reason why the Honey Board funded this study must surely be to demonstrate that adding honey (i.e., sugar) to your yogurt is good for you.  And don’t we all love results like this?

Industry sponsored marketing of the week: Honey

Honey has an industry behind it?  Of course it does.

The National Honey Board (a USDA-sponsored checkoff entity) is working hard to convince dietitians that honey is a health food.  Here are three examples sent to me by members of the Academy of Nutrition and Dietetics, who received these ads via e-mail.

I.  “Harness the power of honey in the Mediterranean diet this summer…Incorporating honey into the MSDP [Mediterranean-style dietary pattern] is a natural fit.”

II.  Another reader, Katherine Walcott, sent me this one about how honey can boost probiotics.  She points out that the ad links to an article in health.com and then to studies one and two , both supported by the National Honey Board.

III.  Yet another dietitian sent me yet another ad, this one featuring dietitians extolling the benefits of honey as part of nutritious diets.

RD: Honey offers antioxidants, heart health and more

Honey may offers numerous healthful benefits: it is rich in antioxidants like flavonoids and phenolic acids, which help neutralize reactive oxygen species, potentially reducing the risk of conditions like premature aging, Type 2 diabetes and heart disease, writes registered dietitian nutritionist SaVanna Shoemaker. Honey may aid in blood sugar management by increasing adiponectin levels, though it should be consumed in moderation, especially by people with diabetes. Studies suggest honey can improve heart health by lowering blood pressure and improving blood fat levels. It also has antibacterial and anti-inflammatory properties, making it effective for treating burns, wounds and coughs in children over 1 year old, however honey should never be given to children under 1 year of age.

Comment

I need to point out the obvious: honey is a form of sugar.  It is a mix of sucrose, glucose, fructose, and traces of other sugars, minerals, and flavors.  Its main benefits?  It is delicious, but most people are unlikely to eat much of it, and not nearly as much as they might eat of sucrose table sugar.  Can it be part of nutritious diets?  Of course it can.  A health food?  Depends on how much you eat of it.

Also obvious: the purpose of the National Honey Board is to convince you to eat more honey.

Industry-funded study of the week: artificial sweeteners

Thanks again to Jim Krieger of Healthy Food America for sending this one.

The study: Sievenpiper JL, Purkayastha S, Grotz VL, Mora M, Zhou J, Hennings K, Goody CM, Germana K. Dietary Guidance, Sensory, Health and Safety Considerations When Choosing Low and No-Calorie Sweeteners [LNCSs]. Nutrients. 2025 Feb 25;17(5):793. doi: 10.3390/nu17050793.

The greater sweetness intensity of LNCSs compared to sucrose allows for the use of lesser amounts to achieve a similar level of sweetness, facilitating a reduction in an individual’s caloric and sugar consumption. Furthermore, the substitution of LNCSs for sugar supports individual and public health outcomes by addressing issues related to obesity, diabetes, and chronic illnesses…Lastly, emerging evidence from in vitro and a randomized controlled trial have investigated food intake and satiety management and suggests that natural LNCSs may be beneficial…The diverse range of LNCSs available in global food and beverage choices, coupled with their varying sweetness intensities, offers enjoyment and pleasure to consumers on their respective health and wellness journeys.

Funding Statement: The development of this paper received support from Pure Circle, Ingredion, Inc. The contents are solely the responsibility of the authors and do not necessarily represent the official views of Pure Circle, Ingredion, Inc.

Comment: Because these authors have so many conflicted interests, I’ll save their declarations for last. This paper is explicitly reviews the benefits of low- and no-calorie sweeteners.  On that score, I find it useful.  It is comprehensive and well written; if you want an uncritical review of the benefits of artificial sweeteners, this is the place to start.  Its summary of international front-of-package labels alone makes it a valuable resource.  But do not expect to find a deep analysis of the potential hazards of alternative sweeteners; these authors dismiss or discredit that evidence out of hand.  No surprise:  The funder, Ingredion, Inc, makes alternative sweeteners, four of the authors work for Ingredion, and four others were paid for writing the paper.  This makes this review a company project.  The conflict-of-interest statement gives the authors’ affiliations and the lead author, John Sievenpiper, provides another notable disclosure statement of this work for hire (see one of my previous posts on his alliances with food companies).

Conflict of interest statement: The following authors are employed at Ingredion, Inc.: Margaux Mora, Jing Zhou, Katie Hennings, and Kristen Germana.

Industry-funded study #2: artificial sweeteners

Thanks to Arjan van Groningen for this one.

The study:  The Effect of Non-Nutritive Sweetened Beverages on Postprandial Glycemic and Endocrine Responses: A Systematic Review and Network Meta-analysis. Zhang, R.; Noronha, J.C.; Khan, T.A.; McGlynn, N.; Back, S.; Grant, S.M.; Kendall, C.W.C.; Sievenpiper, J.L. Nutrients 2023, 15, 1050. https://doi.org/10.3390/nu15041050.

Conclusions: The available evidence suggests that NNS beverages sweetened with single or blends of NNS have no acute metabolic and endocrine effects, similar to water. These findings provide support for NNS beverages as an alternative replacement strategy for SSBs in the acute postprandial setting.

Funding: This work was supported by an unrestricted grant from the Institute for the Advancement of Food and Nutrition Sciences (IAFNS). The grant was awarded through a competitive request for the proposal process. The sponsor was not involved in the development of the study protocol and design, execution, analyses, interpretation of the data, or decision to publish. The protocol and results were presented to the Low- And No-Calorie Sweeteners Scientific Committee of IAFNS on several occasions with an opportunity for scientific dialogue.

American Society for Nutrition commissions highly conflicted meta-analysis

I was surprised to see a press release from the American Society for Nutrition (ASN—of which I am a member) announcing publication of a research paper the Society had commissioned and published on sugars and body weight: Important food sources of fructose-containing sugars and adiposity: a systematic review and meta-analysis of controlled feeding trials.

The paper, the press release said, “Illustrate[s] The Need for Nuance in Public Health Guidance Related to Consumption of Sugars: Findings call into question recommendations that imply all sources of fructose-containing sugars carry the same risk.

The press release notes that “this comprehensive review is timely as the 2025 Dietary Guidelines Advisory Committee currently assesses the latest science to inform updated evidence-based recommendations,” and it quotes the lead author: “There is an opportunity for more food-based guidance around sugars to help ensure Americans don’t inadvertently eat less health-promoting foods containing fructose – especially at a time when most people don’t eat enough of all forms of fruit, which offer significant health benefits.”

Uh oh.  This is an easily misinterpreted message.

My immediate question:  Who wrote the paper ?

No surprise.: authors with extensive conflicts of interest.

I’ve written about some of these authors’ conflicts of interest disclosures previously.  See, for example. this, this, and this.

Just for fun, I’ll post this particular statement of the conflicted interests at the end of this post.

Basically, these authors do not understand the difference between a conflict of interest (financial ties, which are discretionary) and non-discretionary viewpoints (all researchers have them).  In this case, consulting for a sugar company is a conflict; being a vegan or avoiding sugar-sweetened beverages is not.

My second question: Why did ASN commission this paper, and from these particular authors no less?

I contacted John Courtney, the long-time executive director of the ASN.  He said this was a leftover from an initiative started ten years ago.  Since then, the ASN has decided not to commission papers on controversial topics and this will not happen again.

Good.  It shouldn’t.  Commissioning papers like these make the ASN look like an arm of the food industry.  The ASN should avoid even teh appearance of conflicts of interest as much as it possibly can.

You don’t believe this is a problem?  Take a look at this conflict of interest statement.  Enjoy!

Industry-influenced commentary of the week: soy foods should not be considered ultra-processed

The commentary: Perspective: Soy-Based Meat and Dairy Alternatives, Despite Classification as Ultra-Processed Foods, Deliver High-Quality Nutrition on Par With Unprocessed or Minimally Processed Animal-Based Counterparts.  By Mark MessinaJohn L SievenpiperPatricia WilliamsonJessica KielJohn W Erdman, Jr.  Advances in Nutrition, nmac026, https://doi.org/10.1093/advances/nmac026

Purpose: “This perspective argues that none of the criticisms of UPFs [ultra-processed foods] apply to soy-based meat and dairy alternatives when compared with their animal-based counterparts, beef and cow milk, which are classified as unprocessed or minimally processed foods (group 1). Classifying soy-based meat and dairy alternatives as UPFs may hinder their public acceptance, which could detrimentally affect personal and planetary health. In conclusion, the NOVA classification system is simplistic and does not adequately evaluate the nutritional attributes of meat and dairy alternatives based on soy.

Conflicts of interest: the statement is so long that I will save it for the end.

Comment: This commentary is a critique of the NOVA classification system, which puts foods in four categories by level of processing:

  • Group 1: Unprocessed/minimally processed (fruit, vegetables, nuts, grains, meat, milk with no complicated additives)
  • Group 2: Processed culinary ingredients (oils, fats, butter, vinegars, sugar, and salt eaten with added to Group 1)
  • Group 3: Processed (mix of groups 1 and 2, chiefly for preservation)
  • Group 4: Ultra-processed (industrially produced, cannot be made in home kitchens, chemical additives)

By this time, literally hundreds of studies have linked frequent consumption of ultra-processed (“junk”) foods to weight gain and its associated chronic diseases—type 2 diabetes, heart disease, etc—as well as high risk for poor outcome from COVID-19.  One carefully controlled clinical trial has shown that ultra-processed diets induce people to unwittingly take in more calories (“you can’t eat just one.”).

Artificial meats and dairy products made with plant proteins clearly meet the definition of ultra-processed.   Are soy products in a different category from those made with pea protein, for example?  Should plant-based meats in general be exempt from being considered ultra-processed?

I don’t think we know yet whether these products are better for health and the environment.  The issues are complicated and we don’t yet have the research or experience.

These authors report conflicted ties—many such ties—to companies making soy products and other products that might be considered ultra-processed:

Conflict-of-interest disclosure of the week

A reader, Effie Schultz, sent this one, with a comment that it comes with the longest conflict of interest statement she had ever seen (I’ve noted one that was two pages long in the first item in a post in 2015).

Association of Low- and No-Calorie Sweetened Beverages as a Replacement for Sugar-Sweetened Beverages With Body Weight and Cardiometabolic Risk: A Systematic Review and Meta-analysis.  McGlynn ND, and 20 other authors.  JAMA Network Open, March 14, 2022. 2022;5(3):e222092.  doi:10.1001/jamanetworkopen.2022.2092

The research question: Are low- and no-calorie sweetened beverages (LNCSBs) as the intended substitute for sugar-sweetened beverages (SSBs) associated with improved body weight and cardiometabolic risk factors similar to water replacement?

The conclusion: This systematic review and meta-analysis found that using LNCSBs as an intended substitute for SSBs was associated with small improvements in body weight and cardiometabolic risk factors without evidence of harm and had a similar direction of benefit as water substitution. The evidence supports the use of LNCSBs as an alternative replacement strategy for SSBs over the moderate term in adults with overweight or obesity who are at risk for or have diabetes.

Comment: Research on artificial sweeteners remains controversial.  I think we will be arguing forever about their safety and efficacy in helping people lose weight.  Studies with conflict of interest disclosures like the excessively extensive one here do not help resolve the research questions.

I strongly support revealing conflicted interests that might influence any aspect of research design, conduct, and interpretation.  For this study, I would be interested in financial ties or arrangements with companies that might either gain or lose sales or marketing advantages from results showing artificial sweeteners or diet drinks to be harmless or beneficial, as these do.  At issue here is whether financial ties to companies with corporate interests in the outcome of such research bias results or interpretation, consciously or unconsciously.

You have to search through this mess of unnecessary and distracting disclosures to find the ones that matter.  They are there.  You have to search for them.

Much of what is disclosed is irrelevant and, therefore, not helpful.

You may well disagree with that assessment.  Judge for yourself.
