The study: Maher, C. , Alcorn M., Childress A., Dawson J. A., and Galyean S.. 2025. “Increasing Vegetable Intake Using Monosodium Glutamate in a Randomized Controlled Trial: A Culinary Medicine Intervention.” Food Science & Nutrition 13, no. 6: e70441. 10.1002/fsn3.70441.

Purpose: “This study aimed to explore the effectiveness of monosodium glutamate (MSG) as a flavor enhancer in increasing vegetable intake compared to sodium chloride (NaCl) alone combined with a digital culinary medicine education program.”

Results: “The 50/50 NaCl/MSG group showed a mean increase in vegetable intake from 1.46 to 1.55 cups/day, while the NaCl group showed a decrease from 1.33 to 0.95 cups/day.”

Conclusion: “Although the differences in vegetable intake were not statistically significant, the findings suggest that MSG could enhance vegetable palatability and intake, aligning with the principles of culinary medicine.”

Conflicts of Interest: “The authors declare a conflict of interest due to Ajinomoto’s involvement in the funding and design of this study. Ajinomoto is a company that manufactures and sells MSG products. Their contribution included financial support and assistance in the study design, which could be perceived as influencing the outcomes of the research.”

Funding: “This study was funded by the American Society for Nutrition and its Foundation, grant number 1195905, and the APC [article processing charge] was funded by Ajinomoto.
Health & Nutrition North America Inc.”

Comment: The idea here is that if you sprinkle MSG rather than salt (NaCl) on your vegetables, they will taste better and you will eat more of them.  The study produced a non-significant result but is given a positive spin (“MSG could enhance…”).  The shocker here is the funding.  The authors say Ajinomoto funded it, but the funding statement mentions the American Society for Nutrition, an organization of nutrition researchers and clinicians to which I belong.  I had no idea ASN was funding research, let alone industry-funded research.  I have long been concerned about ASN’s industry partnerships, which I believe compromise the ability of the organization to issue advice on nutrition.  This is an old issue, but one that it seems time to bring up again.

The subject line of this one: “A Surprising Sodium Reduction Tool for Your Clients”

It is an advertisement; it even says so.  But it does not say who paid for it.

To find that out, you have to click on the subscribe or resource links.

Bingo!  Ajnomoto, the maker of MSG.

All of this is to convince dietitians to push MSG as a salt substitute:

 Extensive research has affirmed not only the ingredient’s safety, but its benefits for sodium reduction. Even the National Academies of Sciences, Engineering and Medicine has recognized MSG as a tool to reduce sodium in the food supply.

Is this a good or bad idea?  MSG still has sodium and its health effects remain under debate.

This kind of sponsorship should be disclosed, front and center, in ads like this, especially because much of the research demonstrating benefits of MSG was funded by guess which company.

The Academy of Nutrition and Dietetics should not permit ads that lack full disclosure.

Members: Complain to the Academy that you want these ads to stop.

Thanks to Jackie Bertoldo for alerting me to this one.

Last week, Allison wrote: “I recently read the NYTimes article about MSG [monosodium glutamate] and although you were quoted, I’d love to hear more of your thoughts.”

This is a tough one. My files on MSG go back to 1971 when the FDA said this flavor enhancer, the sodium salt of an amino acid that forms part of virtually all proteins, was safe for everyone “except for those who are individually sensitive to the substance.” By these, it meant people who reacted to foods containing MSG with headaches, tingling, flushing or other such neurological symptoms. Because Chinese food contained a lot of MSG, the symptoms came to be known as “Chinese Restaurant Syndrome.” In the late 1970s, scientists weighed in with reports of placebo-controlled trials that showed no reaction to MSG except for the first half hour after eating it. By 1980, scientists concluded that MSG only caused problems for a small percentage of individuals who had a genetic susceptibility. Placebo-controlled trials continue to find no difference in symptoms when people consume MSG or a placebo. That is why I told the reporter that there was no clinical evidence for problems and why “I thought the issue was settled though I know a lot of people will never believe that.” I wish what I had said next had been included because I went on to explain that such studies cannot account for the very real experience of people who experience symptoms, such as those whose letters appear in today’s Times.

How to make sense of this? MSG susceptibility falls into the category of many other food sensitivities and allergies, most of which are exceedingly difficult to diagnose. The science of food sensitivities, like much of nutrition science, is difficult to do, especially when serious symptoms are relatively rare in the population (it is too expensive to do studies on a large enough sample of individuals to get meaningful results).

If you are one of those people who experiences symptoms from MSG, there is only one thing to do: avoid it. And that brings us to the need to have more informative food labels. One again, we are in the realm of food politics.

At a glance across the country: Meatpacking plants closed at an unprecedented rate this year, accelerated by a number of factors such as rising livestock costs, workforce shortages, food safety violations and foodborne illnesses, and ongoing industry consolidation.

Here are some examples: of these and others:

• Tyson closes 3 meat plants, lays off 1K workers The food giant plans to shutter its 328,000-square-foot facility in Emporia, Kansas, as well as two cheesesteak factories in Philadelphia.
• Cargill cuts 5% of global workforce after profits decline The move, which will affect approximately 8,000 jobs, comes as the world’s largest private company plans to streamline operations in the face of lower crop prices and challenges in beef.
• Deere lays off more workers at Iowa tractor plant The cuts add to the thousands of jobs eliminated this year as the equipment maker reigns in production to offset a slowdown in demand.
• Butterball to shutter Arkansas turkey plant, lay off 180 workers: The closure adds to a wave of layoffs in the agriculture industry as weaker sales continue to hurt profits across the sector.

The last couple of years have seen lots of these.  It will be interesting to see what happens this year, especially with immigration “reform” looming on the horizon.  Pretty certain: food prices will rise. A lot.

PUMPKINS

World’s largest pumpkin: Minnesota grower wins again at World Championship Pumpkin Weigh-Off. 2,471 pounds. That wasn’t enough to beat the world record he set last year — that pumpkin was 2,749 pounds.

Scaring Halloween Trick-or-Treaters Is Free. But This Pumpkin? $13.50: Each application of pepper spray for pests costs the Dykemans, who calculate many expenditures by acre, about $150 per acre. Two charcoal filters, $400 apiece, protect operators in this John Deere tractor ($67,000 in 2008), which takes $130 of diesel. Fertilizer prices, which soared in part because of Russia’s invasion of Ukraine, have come down in recent months. But it remains a significant cost, the Dykemans said, at $200 per acre.

Pumpkin Seeds: A Tiny Seed With Big Benefits: With Halloween just around the corner, pumpkins are everywhere! However, many people overlook a highly nutrient-rich part of the pumpkin – the seeds…For instance, just a small handful provides around 40% of the recommended daily value for magnesium

Pumpkins: Background & Statistics: All States produce some pumpkins, but six States produce most of them. According to the most recent USDA, Census of Agriculture, in 2022, about 45 percent of pumpkin acres were harvested in the top six pumpkin-producing States, measured by pumpkin weight.

The walnut industry must be desperate for greater market share.  Walnuts are great and make a terrific snack if you don’t eat too many of them (calories!).  But this is one-food research.  Can one food really make an important difference to health (yes, if you are seriously deficient in essential nutrients but most Americans are not).

One-food research has to be about marketing more than science.

To wit:

A Cross-Sectional Study on the Association of Walnut Consumption with Obesity and Relative Fat Mass among United States Adolescents and Young Adults in NHANES (2003–2020).  2024 Current Developments in Nutrition.  DOI: https://doi.org/10.1016/j.cdnut.2024.104407

Conclusions: For adolescents girls and young women, dietary intake of walnuts combined with other nuts has the strongest inverse association with measures of obesity.

Funding: This study was funded by the California Walnut Commission.

Comment

The study does not find an association between eating walnuts and obesity in adolescents.  I would not expect it to.  People do not eat that many walnuts.  They get most of their calories from fast and ultraprocessed foods.

The California Walnut Commission would like you to think the calories in walnuts do not count.  In a press release, it points out

Nuts, including walnuts, are nutrient dense and considered a key component of many recommended dietary patterns, including the Mediterranean and vegetarian diets. They are also recommended for daily consumption in the latest U.S. Dietary Guidelines.³ Despite the recommendations, nuts remain under-consumed by the U.S. population,³ perhaps due to nuts being calorie dense, leading to potential concerns that including nuts in the diet could promote weight gain. But new research suggests people, especially Gen Z and millennials, should reconsider nuts, like walnuts.

All true, but nuts in general, not specifically walnuts.  This is about increasing the market share for walnuts as opposed to other nuts.

Thanks to everyone who flooded my mailbox with this piece from The Guardian: She was fired after not endorsing Splenda-filled salads to people with diabetes. Why?

According to a lawsuit {Elizabeth] Hanna recently filed against the ADA, the organization – which endorses recipes and food plans on its websiteand on the websites of “partner” food brands – tried to get her to greenlight recipes that she believedflew in the face of the ADA’s mission. These included recipes like a “cucumber and onion salad” made with a third of a cup of Splenda granulated artificial sweetener, “autumnal sheet-pan veggies” with a quarter cup of Splenda monk fruit sweetener and a “cranberry almond spinach salad” with a quarter cup of Splenda monkfruit sweetener.

Guess which company gave more than $1m to the ADA in 2022? Splenda.

I also was sent an email from Georgia Warren, the  Guardian’s Interim membership editor: The link between investigative reporting, some nightmarish recipes and the diabetes epidemic.

Why would a public health charity promote a product that its own science shows contributes to the disease it is fighting? Well, as Neil Barsky reported for us this week, the ADA took more than $1m from Splenda in 2022 – and then fired their chief nutritionist when, according to a lawsuit she recently filed, she refused to sign-off on the Splenda-based recipes that her bosses wanted the ADA to publicly endorse.

Neil – creator of our new series ‘Death by diabetes: America’s preventable epidemic’ – told me…“The ADA has bought into a system that requires them to raise money from corporations to fund their research. I don’t for a second doubt that every single person who works there cares about people with diabetes and wants to do the right thing, but being beholden to these groups distorts your judgment.”

..And what else is pharma funding? The ADA. The organization – whose guidance doctors rely on when treating their diabetes patients – boasts a $100m annual budget. Between 2017 and 2024, pharmaceutical and device manufacturers contributed over $134m to the organization – or roughly 20% of its total funding.

Comment: The ADA has long appeared to be in thrall the the drug industry.  I well remember the talk I gave at one of its annual conventions years ago.  I was one of two speakers about diet and diabetes (the other was a session on the role of sugar in diabetes sponsored by Coca-Cola—truly you can’t make this stuff up).  The other talks, hundreds of them, were about drugs.  At that time, the ADA said virtually nothing about diet on its website.

It’s gotten much better.  Here’s what it says about carbohydrates:

• Try to eat less of these: refined, highly processed carbohydrate foods and those with added sugar. These include sugary drinks like soda, sweet tea and juice, refined grains like white bread, white rice and sugary cereal, and sweets and snack foods like cake, cookies, candy and chips.

And here’s what the ADA says about artificial sweeteners:

It’s also important to know that at this time, there is no clear evidence to suggest that using sugar substitutes will help with managing blood sugar or weight or improving cardiometabolic health in the long run. So here’s the bottom line:

• Sugar substitutes are effective alternatives to sugar for some people, but not a perfect fit for all—it’s a personal choice.
• If you’re looking to reduce your intake of sugar or sugar substitutes, start slowly. For example, start by replacing one soda or juice with water or a no-calorie drink at a time.
• Water will always be a great choice! If you start feeling yourself get bored with just water, you can always spruce it up with fruits or herbs like this sparkling strawberry mint infused water.

And, finally for now, here are the ADA’s corporate sponsors, and its national sponsors.

Conflicted?  Sure looks like it.
