Many individuals goal to begin the 12 months off with more healthy meals selections. But how do you select between seemingly comparable meals, snacks or drinks? How does a bagel with cream cheese examine to toast topped with avocado, as an illustration? Or a protein-based shake in comparison with a smoothie filled with fruits? Or two hen dishes, ready in numerous methods?
As diet scientists who’ve spent our total careers finding out how completely different meals affect well being, our crew at Tufts University has created a brand new meals score system, the Food Compass, that would assist shoppers and others make knowledgeable selections about these sorts of questions.
Food score programs defined
Many such programs exist and are broadly used across the globe. Each one combines information about completely different dietary elements of meals to supply an general measure of healthfulness, which may be communicated to shoppers by means of bundle labels or shelf tags. They may also be used to assist information product reformulations or socially aware funding targets for traders.
Examples of widespread programs embrace Nutri-Score and Health Star Rating – broadly utilized in Europe, the U.Ok., Australia and New Zealand – and “black field” warning label programs, that are more and more used all through Latin America.
All such meals score programs have strengths and limitations. Most goal to be easy, utilizing information on only a few vitamins or elements. While that is sensible, it could omit different vital determinants of healthfulness – just like the diploma of meals processing and fermentation and the presence of various meals elements or vitamins like omega-3s and flavonoids, plant compounds that provide an array of well being advantages.
Some programs additionally emphasize older diet science. For instance, practically all give unfavorable factors for whole fats, no matter fats kind, and give attention to saturated fats alone, slightly than general fats high quality. Another widespread shortcoming shouldn’t be assessing refined grains and starches, which have comparable metabolic harms as added sugars and characterize about one-third of energy within the U.S. meals provide. And many give unfavorable factors for whole energy, no matter their supply.
Enter the Food Compass
To deal with every of those gaps, in 2021 our analysis crew created the Food Compass. This system assesses 54 completely different attributes of meals, chosen based mostly on the power of scientific proof for his or her well being results. Food Compass maps and scores these attributes throughout 9 distinct dimensions after which combines them right into a single rating, starting from 1 (least wholesome) to 100 (most wholesome). It incorporates new science on a number of meals elements and vitamins; doesn’t penalize whole fats or give attention to saturated fats; and provides unfavorable factors for processing and refined carbs.
We have now evaluated 58,000 merchandise utilizing Food Compass and located that it typically performs very nicely in scoring meals. Minimally processed, bioactive-rich meals like fruits, veggies, beans, entire grains, nuts, yogurt and seafood rating on the prime. Other animal meals, like eggs, milk, cheese, poultry and meat, sometimes rating within the center. Processed meals wealthy in refined grains and sugars, like refined cereals, breads, crackers and vitality bars, and processed meats fall on the backside.
We discovered Food Compass to be particularly helpful when evaluating seemingly comparable meals gadgets, like completely different breads, completely different desserts or completely different combined meals. Food Compass additionally seems to work higher than present score programs for sure meals teams.
For instance, it offers decrease scores to processed meals which can be wealthy in refined grains and starch and to low-fat processed meals which can be typically marketed as wholesome, like deli meats and scorching canines, fat-free salad dressings, pre-sweetened fruit drinks, vitality drinks and coffees. It additionally offers greater scores to meals wealthy in unsaturated oils, like nuts and olive oil. Compared with older score programs, these enhancements are extra aligned with the newest science on the well being results of those meals.
We additionally assessed how Food Compass pertains to main well being outcomes in individuals. In a nationwide pattern of 48,000 Americans, we calculated every individual’s particular person Food Compass rating, starting from 1 to 100, based mostly on the completely different meals and drinks they reported consuming.
We discovered that folks whose diets scored greater in line with Food Compass had higher general well being than these with decrease scores. This contains much less weight problems, higher blood sugar management, decrease blood stress and higher blood levels of cholesterol. They additionally had a decrease danger of metabolic syndrome or most cancers and a decrease danger of demise from all causes. For each 10-point greater Food Compass rating, an individual had a couple of 7% decrease danger of dying. These are vital findings, displaying that, on common, consuming meals with greater Food Compass scores is linked to quite a few improved well being outcomes.
While we imagine Food Compass represents a major advance over present programs, extra work is required earlier than it may be rolled out to shoppers.
As one step, we’re investigating how the scoring algorithm may be additional improved. For instance, we’re contemplating essentially the most acceptable scoring for meals gadgets like sure cereals which can be excessive in entire grains and fiber however are additionally processed and have added sugar. And we’re trying on the scoring of various egg, cheese, poultry and meat merchandise, which have a variety of scores however generally rating a bit decrease than could make intuitive sense.
Over the approaching 12 months we shall be refining and enhancing the system based mostly on our analysis, the newest proof and suggestions from the scientific neighborhood.
In addition, extra analysis is required on how a client would possibly perceive and use Food Compass in apply. For instance, it could possibly be added as a front-of-pack label – however would that be useful with out extra schooling and context?
Also, whereas the scoring system ranges from 1 to 100, might it’s extra accessible if scores have been grouped into broader classes? For occasion, would possibly a inexperienced/yellow/purple visitors gentle system be simpler to grasp?
And we’re hoping that future Food Compass variations would possibly include further standards to filter meals for individuals who comply with particular diets, resembling low-carb, paleo, vegetarian, diabetic-friendly, low-sodium and others.

Food Compass shouldn’t be used to interchange food-based dietary tips and preferences. Raspberries and asparagus rating very well – however a weight loss program of solely these meals wouldn’t be very wholesome. People ought to search a balanced weight loss program throughout completely different meals teams.
To assist, Food Compass could also be most helpful to check comparable merchandise inside a meals group. For instance, somebody who prefers eggs for breakfast can search for higher-scoring egg dishes. Those preferring cereal can search for higher-scoring cereals. And even higher, Food Compass might help individuals add different highest-scoring meals to their plate – like veggies and wholesome oils to eggs, and fruit and nuts to cereal – to extend the general well being advantages of that meal.
To make use by others as simple as attainable, we’ve revealed all the small print of the scoring algorithm, and the scores of the merchandise evaluated, in order that anybody can take what we’ve carried out and use it.
Stay tuned – as we full further analysis, we imagine Food Compass will develop into an vital instrument to clear up confusion within the grocery retailer and assist individuals make more healthy selections.
