Industry-funded study of the week: a live-forever dietary supplement

When I saw this ad in last Thursday’s New York Times, I immediately clipped it out.

What is this?

It is an ad for a dietary supplement, Telos95, with a classic structure/function claim (a type invented for dietary supplements of less-than-established efficacy): “telomere & DNA chromosome health support—-telomere lengthening and lowering cellular age in just 6 months.”

Telos95 is the only plant-based dietary supplement that aids in the chromosome stability during the process of cell replication.  It’s vital that normal cell replicative senescence takes place, so the cells divide in a healthy state and telomeres remain at the same length or lengthen, which biologically ensures a health centrosome matrix and repetitive nucleotide sequence at each end of the chromosome.

Got that?

What’s with telomeres?

All of this refers to work that got a Nobel Prize for Elizabeth Blackburn, Carol Greider, and Jack Szostak in 2009.  They showed that telomeres, caps on the end of chromosomes, protect chromosomes from degradation.  Shorter telomeres are associated with cell aging.

What got my attention in this ad was its report of a 2018 clinical trial finding that this supplement reduced cellular age by more than 7 years.

Really?  I had some immediate questions.

What’s in the supplement? 

The ad doesn’t say anything other than “all natural food grade polyphenols.”  But I managed to find a Supplement Facts Label online.

Highly purified polyphenols extracted from grape and olive leaves?

These, by the way, cost about $100 for 30 capsules.

Whatever.

What’s the study? 

I was able to find it online: A randomized-controlled clinical study of Telos95® , a novel antioxidative dietary supplement, on the shortening of telomere length in healthy volunteers  

It’s in a journal I’ve never heard of previously: HealthMed, published in Bosnia and Herzogovina

The report of the study starts out rather peculiarly:

The objective of this study was to determine the deodorant effectiveness of a dietary supplement to halt the shortening of telomere length as measured through blood samples before and after product use.

Deodorant?  Maybe something is lost in translation here?

Who paid for the study?

The published paper doesn’t say.  It does, however, refer to a Sponsor responsible for the study’s protocols, safety evaluation of the products, and safety indemnification of Princeton Consumer Research Corp (PCR), the group that carried out the study.

PCR’s website, by the way, states that “PRINCETON CONSUMER RESEARCH IS NOT AFFILIATED IN ANY WAY TO PRINCETON UNIVERSITY”.  Whew.

PCR’s press release credits Certified Nutritionals as behind the study.

What is this all about?

The Daily Beast did an investigative report on something similar a couple of years ago.

Obviously, this is about selling a supplement made from rice at profits so great that Longevity by Nature can afford a full-page ad in the Times (these used to run in the $80,000 range, if not more).

It is also about the use of industry-sponsored research to sell products: the sponsored study –> press release –> huge advertisement –> increased product sales.

Will this product keep your telomeres from shortening?  If only.

Weekend reading: the latest on plant-based meat and dairy alternatives

I don’t know about you but I am having a hard time keeping up with what’s happening in the market for plant-based meat and dairy substitutes.

For one thing, they are under attack from meat producers.  Here’s the latest on the politics.

Why the attack.  Just take a look at what I’ve collected on this topic in the past couple of weeks.  You can see at a glance why this trend is taking off.  Everyone wants to get into this act in every way they can.

The latest Romaine lettuce outbreak: Just say no.

The CDC continues to track the latest outbreak of illnesses caused by eating Romaine lettuce contaminated with E. coli O157:H7.

The outbreak at a glance:

The FDA’s advice:

Consumers should not eat romaine lettuce harvested from Salinas, California. Additionally, consumers should not eat products identified in the recall announced by the USDA on November 21, 2019.

A former FDA official, Stephen Ostroff, says:

With five multistate outbreaks in less than two years, it’s clear there’s a serious continuing problem with E. coli O157:H7 and romaine lettuce. The natural reservoir for this pathogen is ruminant animals, especially cattle. Moreover, one particular strain of E. coli seems to have found a home in the growing regions of central coastal California, returning each fall near the end of the growing season.

It’s not clear where this strain is hiding. Cattle? Water sources? Elsewhere? What is clear is that additional steps must be taken to make romaine safer.

The New Food Economy emphasizes some particularly distressing aspects of this particular outbreak.

  • It is caused by the same strain of E. coli O157:H7 that caused outbreaks linked to leafy greens in 2017 and to Romaine lettuce in 2018.
  • This strain of E. coli seems particularly virulent: 39 of the 67 cases had to be hospitalized.
  • The source has not yet been traced.

Consumer Report’s advice: ”

People should avoid all romaine lettuce and that any currently in refrigerators should immediately be thrown out because of the risk of E. coli contamination…CR’s experts think it is prudent and less confusing for consumers to avoid romaine altogether, especially because romaine is also sold unpackaged and in restaurants, and customers can’t always be sure of the origin that lettuce.  “Much of the romaine lettuce on the market at this time of year is from Salinas,” says James E. Rogers, Ph.D., director of food safety research and testing at Consumer Reports.

Food safety lawyer Bill Marler says enough is enough; It’s time to put warning labels on Romaine lettuce.

Marler’s advice: when in doubt, throw it out.

My comment:  Contamination of vegetables with toxic E. coli means that the vegetables somehow came in contact with waste from farm animals or wild animals or birds.  The most likely suspect is Confined Animal Feeding Operations (CAFOs) or large dairies because they produce so much animal waste.  If one animal is infected under crowded CAFO conditions, other animals also will be infected (but cows don’t show symptoms).

Preventing lettuce contamination means that CAFOs must manage their waste so that it is not infectious (USDA and EPA regulated) and vegetable farms must keep infected water from contaminating their crops (FDA regulated).  All of this means following food safety procedures to the letter, but also in spirit.

Constant Romaine outbreaks are further evidence for the need for consistency in USDA and FDA food safety policies, and a reminder that calls for a single, united food safety agency have been coming for more than 40 years.  Surely, it’s time.

Weekend reading: history of American cuisine

Paul Freedman.  American Cuisine: And How it Got that Way.  Liveright Publishing, 2019.

Paul Freedman is an historian at Yale who in recent years has taken on food history.  His previous book, Ten Restaurants that Changed America, was on my weekend reading list in 2016.

This one covers the history of cuisine in America, addressing basic questions such as “is there such a thing as American cuisine?,” “What happened to it?,” and “What is likely to happen to it?”

The chapters cover such things as culinary nostalgia, community cookbooks, industrial food, ethnic restaurants, and the food revolution.  My favorite chapter title: “Have your cake, choose from our fifteen fabulous flavors, and eat it too.”

It’s a good read.  Here is a sample from page 367:

Americans have been enthusiastic consumers of modern products.  It is not just that historically the United States was technologically precocious or that its citizens value convenience, although these are true.  The key factor is a peculiar attitude toward food.  Americans have attempted to apply ideas about health and efficiency to diet.  Obsessed with technological progress, anxious about time-saving, and worried about physical well-being, Americans for well over a hundred years have embraced scientific nutrition, industrial food, and convenience.  They have been willing to sacrifice tradition and regional variation in favor of standard brands and their array of flavor and style.  Infatuation with science, convenience, and variety require giving up the natural taste of food in favor of texture, color, multiplicity, and simplicity of preparation.  Quick, easy, and healthful have been more important than flavor.

This is also a beautiful book, printed on high-quality paper, in an attractive easy-to-read font, and lavishly illustrated with menus, recipes, and pictures of advertisements, book covers, places, and people, many of them in color.

Reading it made me want to re-read Laura Shapiro’s Perfection Salad and Something From the Oven, both cited by Freedman in his chapter titled “women and food in the twentieth century.”

Industry-funded study of the week: Potatoes (they improve athletic performance!)

The study: Potato ingestion is as effective as carbohydrate gels to support prolonged cycling performance.  Salvador AF, et al.  J Applied Physiology, 17 October 2019.

Conclusion: “Potato and gel ingestion equally sustained blood glucose concentrations and TT [time-trial] performance. Our results support the effective use of potatoes to support race performance for trained cyclists.”

Funder: The Alliance for Potato Research and Education, “a not-for-profit organisation funded by the potato industry in the US.”

Comment:  I learned about this study from an article in NutraIngrendients.com: “Powered by potato? Spuds ‘just as good’ as carb gels for athletic performance, says study.”

Despite my previous correspondence and interview with the editor of NutraIngredients, the article failed to mention the study’s industry sponsor.

This was especially disappointing because its sister publication, FoodNavigator.com, covered the same study but quoted the funding statement.

The study’s title and result should have triggered a look to see who paid for it.  Really?  Cyclists are supposed to carry potatoes with them to eat on long races?   Why would anyone other than potato sellers even think of such a thing?

Addition: But see comments from readers…

I was interested to hear this from Courtney Puidk, a dietitian:

Love your industry updates – BUT actually using potatoes as fuel has been a thing with cyclists for a long time. I have several friends and an ex who used baked potatoes as fuel during bike races and triathlons because potatoes are 99% glucose so they shoot through you fast, and they have lots of potassium and sodium so act as natural electrolytes. They fit nicely into the pockets of cycling jerseys and/or water bottle holders. And they’re cheap! Not to mention a whole food fuel source over some pricey, marketed sugar gel with lots of packaging.  Plenty of reasons to use potatoes as fuel!

And Simone Braithwaite, a reader from Australia, writes:

A friend of mine recently did the Comrades Marathon in South Africa. She has now done the 100km twice – once for each direction. Funny thing is, on the course the provided energy source is boiled potatoes (with salt). Runners actually carrying boiled potatoes along as they trudge this arduous race, apparently nibbling/sucking as they go.  In this developing world context I actually thought this was excellent as potatoes are an affordable and accessible food source for all. I also wondered how long this tradition would last – before multinationals got in with their ‘superior’ ultra processed products. Maybe this is one case where this study will be most useful!!!?

OK.  I concede.

Plant-based meat and dairy: recent innovations

I’ve been collecting items related to plant-based meat and dairy foods from the various newsletters I read.  I am having a hard time keeping up.  This is a super-hot topic with investors pouring money into these products.

Things are moving so quickly that Food Dive has established a plant-protein tracker to help readers keep up.

Even a quick scan of just the titles of these articles will make clear just how hot this area is.

Let’s start with the in-fighting.

Here’s what he’s talking about.  I’ll bet they don’t agree.

As for what the meat industry thinks of all this…

And the New York Times’ take on Big Meat’s getting in on this action.

Hey–Sugar is Plant-Based!

I love the Sugar Association, the chief lobbying group for producers of sugar cane and sugar beets, for its endlessly creative ways of trying to convince that more sugar is good for us. [Note: High Fructose Corn Syrup is represented by a separate group, the Corn Refiners Association, which does much of the same.]

I was sent this account of  sugar-industry speeches at a symposium run by the American Sugar Alliance, another trade group.

What to do about all those pesky “eat less sugar” messages?  According to one public relations speaker,

The fact that sugar comes from a plant is a positive for consumers…The terms “real” and “pure” create positive associations in consumers’ minds…Consumers believe that honey is “the most healthy and natural” of sweeteners and that high-fructose corn syrup is “not real.”

Only 30% think sugar is naturally grown…A key message should be that “sugar comes from a plant—like sugar beets or sugar cane.  It’s grown on a farm and it’s minimally processed.

As always, you can’t make this stuff up.

BakeryandSnacks.com on “free-from” labels

I love “free-from” labels (no sugar, no salt, no GMOs, no gluten, etc).  My first question is always “OK, so what IS in them?”

But “free-from” works for marketing, as these articles show.

Special Edition: The rise of free from

What is driving the free from trend – grain-free, gluten-free, lactose-free, egg-free, dairy-free, sugar-free, fat-free and even free from additives, animal products and unrecyclable properties – and will it have legs?

Research shows consumers perceive free from (and clean label) products to be healthier and are synonymous with the wider trend of sustainability and social responsibility. However, the big challenge for producers remains to create products that have the same texture, taste and mouthfeel as regular products. Despite their desire for more natural foods, consumers are not prepared to sacrifice these ideals.

We examine the ingredients being developed to accommodate the consumer’s growing penchant for healthy snacking driving the growth of alternatives to traditional snack ingredients.
