A brand new examine demonstrates that consuming primarily minimally processed meals, as they’re outlined by the NOVA classification system, doesn’t mechanically make for a nutritious diet, suggesting that the varieties of meals we eat could matter greater than the extent of processing used to make them.
Evaluating two menus reflecting a typical Western food regimen -; one emphasizing minimally processed meals and the opposite emphasizing ultra-processed meals, as categorized by the NOVA classification system -; the researchers discovered that the much less processed menu was greater than twice as costly and reached its expiration date over thrice sooner with out delivering any extra dietary worth.
“This examine signifies that it’s attainable to eat a low-quality food regimen even when selecting largely minimally processed meals,” mentioned Julie Hess, PhD, a analysis nutritionist on the USDA-ARS Grand Forks Human Diet Analysis Heart, who led the examine. “It additionally reveals that more-processed and less-processed diets might be equally nutritious (or non-nutritious), however the more-processed food regimen could have an extended shelf life and be more cost effective.”
Mark Messina, PhD, director of vitamin science and analysis at Soy Diet Institute World, will current the findings at NUTRITION 2024, the flagship annual assembly of the American Society for Diet held June 29–July 2 in Chicago.
The brand new analysis builds on a examine the crew revealed final 12 months, which demonstrated that it was attainable to construct a high-quality menu that aligns with dietary pointers whereas deriving most of its energy from meals categorized as ultra-processed. For the brand new examine, the researchers requested the alternative query: Is it attainable to construct a low-quality menu that derives most of its energy from “easy” meals?
To search out out, they constructed a less-processed menu, which derived 20% of its energy from ultra-processed meals, and a more-processed menu, which derived 67% of its energy from ultra-processed meals. The extent of processing concerned in every menu was decided in line with the NOVA system of classification.
The 2 menus had been calculated to have a Wholesome Consuming Index rating of about 43-44 out of 100, a comparatively low rating that displays poor adherence to the Dietary Tips for Individuals. The researchers estimated that the less-processed menu would value $34.87 per day per particular person in contrast with $13.53 per day for the more-processed menu. In addition they calculated that the median time to expiration of the less-processed menu gadgets was 35 days versus 120 days for the more-processed menu gadgets.
The examine attracts consideration to the disconnects between meals processing and dietary worth. Hess famous that some nutrient-dense packaged meals might be categorized as ultra-processed, corresponding to unsweetened applesauce, ultrafiltered milk, liquid egg whites and a few manufacturers of raisins and canned tomatoes.
The outcomes of this examine point out that constructing a nutritious food regimen entails greater than a consideration of meals processing as outlined by NOVA. The ideas of ‘ultra-processed’ meals and ‘less-processed’ meals have to be higher characterised by the vitamin analysis neighborhood.”

Messina will current this analysis at 12:45-1:45 p.m. CDT on Sunday, June 30, in the course of the Meals Alternative, Markets and Coverage poster session in McCormick Place (summary; presentation particulars under).
Aims: The “clear consuming” pattern of consuming primarily meals with easy components means that consuming fewer processed meals is a requisite facet of wholesome dietary patterns. But analysis signifies {that a} menu containing largely ultra-processed meals (UPFs) can meet nutrient and food regimen high quality suggestions from the Dietary Tips for Individuals. Whether or not a food regimen comprised largely of easy ingredient meals can present a low-quality food regimen stays unexplored. The target of this examine was to match the food regimen high quality, shelf stability, and value of two related Western-style menus, one containing primarily power from UPFs and the opposite containing primarily power from much less processed meals, as outlined by the Nova meals classification system.Strategies: First, a less-processed model of a Western menu (less-processed Western, LPW; more-processed Western MPW) with a Wholesome Consuming Index (HEI) rating of roughly 43 was developed to align with the HEI rating of the beforehand developed MPW. Processing stage was decided by Nova categorizations assigned by exterior graders. The ultimate menu was assessed for nutrient content material and HEI rating. Shelf stability of meals was decided with info from meals storage steerage manuals. The situation of every meals merchandise when bought (shelf secure, frozen, refrigerated) was used to estimate the variety of days till expiration. Meals and menu prices had been decided utilizing retail costs at a Midwestern grocery chain in Fall 2023.Outcomes: The LPW and MPW had related nutrient densities and HEI scores (44 and 43, respectively). The LPW included 20% power (kcal) from UPFs, whereas the MPW included 67% power from UPFs. Relative percentages of shelf-stable, frozen, and refrigerated meals had been related between the 2. Utilizing the Kaplan-Meier survival evaluation technique, median time to expiration of the LPW menu gadgets was 35 days versus 120 days for the MPW menu gadgets. The “per particular person” value was $34.87/day for the LPW and $13.53/day for the MPW.Conclusions: The less-processed and more-processed menus each supplied low-quality diets. Nonetheless, the LPW was greater than twice as costly because the MPW and had a shorter general shelf life. Degree of processing is just not a proxy indicator of food regimen high quality, and fewer processed meals might be dearer and have a shorter shelf life.Funding Sources: USDA Agricultural Analysis Service undertaking grant #3062-51000-057-00DSource:American Society for NutritionArticle RevisionsJul 3 2024 – Skilled response to unpublished convention presentation on whether or not limiting ultra-processed meals improves food regimen high quality https://www.sciencemediacentre.org/expert-reaction-to-unpublished-conference-presentation-on-whether-limiting-ultra-processed-food-improves-diet-quality/ – Dr. Hilda Mulrooney, Reader in Diet & Well being at London Metropolitan College, mentioned an unpublished examine at Diet 2024 that critiques the NOVA classification system, which categorizes meals based mostly solely on their diploma of processing. She identified that this method overlooks the dietary worth of meals. The examine discovered that it’s attainable to observe a food regimen excessive in ultra-processed meals (UPF) that also meets nationwide dietary pointers.Jul 3 2024 – This story was quickly eliminated pending a evaluate. Whereas the analysis summary and press launch seem to try to debunk the notion that minimally processed meals are inherently more healthy, they overlook a number of key points. Firstly, equating value and shelf life with dietary high quality is deceptive; well being advantages usually come at a worth. Secondly, the low Wholesome Consuming Index scores for each menus may counsel a attainable poorly designed examine, as a genuinely balanced food regimen would rating larger no matter processing stage. Lastly, focusing solely on NOVA classifications with out contemplating meals high quality and nutrient density paints an incomplete image of dietary well being. As soon as the complete peer-reviewed paper is on the market, we are going to replace this story accordingly.Jul 2 2024 – Title modified from “Consuming primarily minimally processed meals doesn’t make for a nutritious diet, examine reveals” to raised talk that this content material is a press launch of outcomes offered at NUTRITION 2024, and isn’t a peer-reviewed journal examine.
