The Rise and Fall of NuVal® Nutritional Guidance by David L. Katz MD MPH, Huffington Post, November 17, 2017:
There are two reasons the
nutrient profiling system known as NuVal®, which assigned a score from 1 to 100, the higher the number the more nutritious the food, has disappeared from the shelves of the nearly 2,000 U.S. supermarkets it populated at its peak. The first reason is that the business model didn’t work; and the second is that the science of the system worked a bit too well.
You will get a very different impression if you read articles with titles such as “
goodbye and good riddance.” But if you Google “NuVal” and read the more prominent disparagements of the system, you would readily find a theme if you looked. Identify the authors, or sources of derogatory comments- and Google them. Generally you will find they make and market highly processed junk food (which, of course, garners the low scores it deserves), or have ties to the beef industry- or they are personal trolls of mine.
...The main source of NuVal criticism is so-called “CPG,” or consumer packaged good companies- otherwise known as food manufacturers. Another is the “
National Consumers League,” which sounds virtuous, but is actually a shell organization founded by those CPGs. This tactic is, apparently, standard operating procedure in propaganda wars. When the giants in the beverage industry wanted to oppose a soda tax in New York, for example, they created a new organization called “New Yorkers Against Unfair Taxes.” You had to dig to discover that soda companies were the exclusive sponsors and organizers.
...As for the science of NuVal, it has mostly failed because it works too well. The algorithm underlying the program was developed by a dozen diverse luminaries in nutrition- including
past and
current chairs of nutrition at the Harvard School of Public Health; the
inventor of the glycemic index; the
inventor of the volumetrics concept; and so on. I was privileged to lead the group, but every decision ran the gauntlet of consensus.
NCL welcomes nationwide removal of misleading nutritional scoring system from grocery shelves, National Consumers League press release, November 9, 2017:
The
National Consumers League (NCL) has welcomed news that a
supermarket-based nutritional scoring system of food products called
NuVal, which at its peak was used in 1,600 grocery stores nationwide,
has been discontinued. For the last five years, NCL has been a vocal
critic of NuVal’s controversial ratings system. In a letter to the U.S.
Food and Drug Administration (FDA) in 2012, NCL called NuVal “fatally
flawed,” pointed out that it gave some junk foods higher nutritional
ratings than canned fruit, and called for its investigation and removal
from grocery stores.
NuVal scored food on a scale of
1-100, with printed labels appearing on shelves next to price labels in
stores that used the system. NuVal claimed to help consumers compare
products by simplifying their nutritional value; the higher the number,
the “better the nutrition.”
“The NuVal rating system
was fatally flawed, and its removal from grocery store shelves is a win
for consumers,” said National Consumers League Executive Director Sally
Greenberg. “Its proprietary algorithmic formula – which was not made
transparent to consumers or the scientific community – resulted in snack
chips, soft drinks, and desserts being given as high or higher
nutritional scores than some canned fruits and vegetables. We welcome
the news that NuVal has been discontinued nationally.”
The
consumer group criticized NuVal’s nutritional ratings as confusing -
not helpful - to consumers trying to make healthy decisions for their
families and called on the FDA to step in and set industry-wide
standards to govern such systems so that they truly benefit
nutrition-minded consumers. Other critics questioned conflicts of
interest behind NuVal’s research and food manufacturers.
The
Yale Daily News reported that, according to NuVal’s creator, Director
of the Yale-Griffin Prevention Research Center David Katz, “Hershey’s
paid him more than $731,000 for research, and Quaker Oats had paid him
more than $633,000. He has also received funds from Kind Bar and
Chobani.”
Goodbye NuVal...and good riddance? by Elaine Watson, Food Navigator, November 13, 2017:
The NuVal shelf tag program – which assigned products a score of 1-100 based on their nutritional value – has been phased out. Good riddance, or do we need a system that attempts to provides consumers with at-a-glance information that helps them rapidly compare products and identify healthier options?
NuVal - which at its peak
featured in 1600+ stores in 31 states including Tops Friendly (Markets) in New York, Raley's in California and Big Y in Massachusetts, factored in positive nutritional attributes as well as negative ones, with nutrients with generally favorable effects on health (eg. vitamins) increasing the score, while nutrients with generally unfavorable effects (trans fat, excess sodium) decreasing the score.
As with any system attempting to apply a standardized approach to thousands of foods across multiple categories, however, it threw up some strange results (read more here at
USA Today and
Yale Daily News), and attracted criticism from
some big CPG brands and the
National Consumers League (NCL) due to its refusal to publish the algorithms underpinning its scores.
...(What) do dieticians think of NuVal's demise?
...Andy Bellatti, Las Vegas-based RD, told FoodNavigator-USA that "Nutrition scoring systems can potentially help consumers, but there are some problematic issues at play, too."
"First, each scoring system has its own formula (which is usually proprietary and kept hidden from consumers). If a formula is based on outdated or murky science (i.e.: any high-fat food, regardless of type of fat, is penalized), it isn't necessarily promoting the healthiest foods out there.
"Second, many of these systems do not take into account ingredients. Nowadays, food manufacturers can use all sorts of nutritionally-empty or even potentially harmful ingredients to tweak values that appear on the Nutrition Facts label to make a product score well.
"Third, this doesn't actually teach consumers anything. Once the scoring system is discontinued, or if a consumer goes to a store where the scoring system isn't used, they don't necessarily have the knowledge to determine what makes a healthful product.
"At the end of the day, I just can't behind the idea that we need complex mathematical equations to determine that lentils are healthful and a high-sugar protein bar isn't a very healthful choice."
Tops to scrap NuVal nutrition ratings criticized as 'fatally flawed' by Samantha Christmann, Buffalo News, October 17, 2016:
Tops Markets is getting rid of a controversial nutrition ratings system it has used to help customers make food purchasing decisions. The system rates brownie mix and ice cream as healthier than some canned fruits and vegetables.
...Leonard H. Epstein, a distinguished professor and chief of behavioral medicine at the University at Buffalo medical school, served on NuVal's scientific advisory board. He said he didn't always agree with the creators' decisions, the system's creators didn't always take the board's advice and that, if he had been one of the system's makers, he "would have done things very differently."
Consumers may find NuVal helpful if their diet is based on general USDA guidelines, Epstein said, but not if they prefer other diets, such as ones high in protein and low in carbohydrates, for example.
..."If you don’t believe in the criteria that NuVal uses, then the algorithm would not work to guide you to healthier eating," he said.
In order to be useful, algorithms have to change to reflect changing science, he said. A shift in emphasis from fat to added sugar in the diet is one example.
Tops said its decision to drop the NuVal system wasn't based on criticism or controversy surrounding NuVal but on customer feedback. As part of an annual evaluation to make sure its programs are relevant, it found there was no increase in customer participation with the program, so the company made the "hard decision" to bring the program to an end.
Raley’s phasing out nutritional scoring system, will develop own program by Mark Glover, Sacramento Bee, October 11, 2016:
West Sacramento-based Raley’s is phasing out a nationally utilized nutrition scoring system by the end of the year and is developing its own program to replace it in 2017.
...Raley’s spokeswoman Chelsea Minor said some customers have found it confusing.
Coborn's replaces NuVal scoring system with in-house nutrition rating program by Matt Perkins, St. Cloud (MN) Times, Oct. 25, 2017:
Coborn's, Inc. has introduced a new nutrition rating program which identifies for customers more than 5,500 products that "support their overall health."
...Endorsed by CentraCare Health, the in-house program replaces the NuVal Nutritional Scoring System, which was recently discontinued nationwide.
..."So what Nuval did was they looked at the overall nutrition and they gave it a score based on that," Kibutha said. "They scored everything. So even if something wasn't healthy, they still gave it a score, whereas we're just putting dietitian-approved on just the items we would endorse for the general public."
..."We have a lot of integrity behind this. It's science-based, 100 percent."
Yale researcher’s ratings service discontinued by Amy Xiong, Yale Daily News, November 3, 2017:
According to (David) Katz, his new company DQPN* is entirely unrelated to NuVal or nutrient profiling.
“DQPN is not at all prone to any kind of conflict, since it is not a scoring system of any kind,” Katz said.
However, four members of DQPN’s team have also worked on NuVal: Harvard professors Walter Willett and Frank Hu, University of Toronto professor David Jenkins and California State University, Long Beach professor Gail Frank.
At a lecture given at Jacksonville University on Oct. 25, Katz stated that the company plans to release an app called DIET ID that reinvents dietary intake assessment by identifying individuals’ dietary patterns and quality.
Four of NuVal’s developers, including three who are now involved with DQPN, did not respond to multiple requests for comment.
