Nutrient Consume Score — NCS
Nutrient Consume Score (NCS) is a science-based tool to make healthy food choices easier. It converts complex nutrition science into simple 1–100 quality scores using key ratios, like carb-to-fiber, tied to microbiome & metabolic health.
Also introducing a public-good, NCS-powered food quality scanner, for finding healthy choices as you shop, eat & cook.
The Calculator
► Type Favorite Food, What is the score?
► Combine 2 Foods, +, How do they mix?
► Type a Wild Card, *, What foods return?
The Score
The NCS algorithm integrates the latest literature on nutrient ratios and bioactives to inform an overall food quality score. It references the USDA’s FoodData Central (FNDDS 2021-2023) for nutrient values of individual foods. NCS scores of 70-100 and subscores of less than 2 correlate with healthier uprocessed & packaged foods.

Maximize green, moderate yellow, and minimize red scoring foods in amount and frequency. Ratio Subscores can be used as guides for combining foods to optimize nutritional balance in meals & recipes.

►Green (100-70): Maximize
►Yellow (69-60): Moderate
►Red (59-0): Minimize

The Evidence

Food processing in its current form has disrupted the natural ratios present in whole food matrixes, concentrating for simple carbohydrates, saturated fats, sodium, and additives while limiting fiber, unsaturated fats, potassium, and bioactives. Some of the latest research is suggesting that disrupted ratios that involve both concentrated and insufficient nutrients are important contributors to the rising rates of gut, metabolic, cardiovascular & neurologic disease.[1,2]
Nutrient ratios that provide a composite score of carb, fat, and micronutrient quality have been associated with a lower odds ratio for metabolic syndrome, diabetes, cardiovascular disease, cancer, and lung disease as well as higher odds ratio for optimal cardiometabolic health.[3,4]

Carb-to-Fiber Ratio (i.e. Carb Quality) is associated with better health[5]: lower depression[6], smaller waist[7], lower diabetes rates[8–10], and less heart disease[11,12]. Fiber slows the absorption of carbs and is converted by the microbiome to factors like butyrate that help to efficiently process them once absorbed. For more information on fiber please follow this link.
Total Fat-to-Unsaturated Fat Ratio (i.e. Fat Quality) is also associated with health: improved blood lipids and glycemic control.[13] For more information on fats please follow this link.
Sodium-to-Potassium Ratio (i.e. Salt Quality) has been associated with lower blood pressure[14] and interventions have lead to decreased blood pressure and stroke.[15] For more information on sodium and potassium please follow this link.
Additives & Bioactives Some unnatural additives like certain sugar alternatives[16], trans fats[17], and some emulsifiers[18] have been linked to poor health markers or outcomes while other natural bioactives like polyphenols[19] and short chain fatty acids (e.g. acetic acid[20], butyrate[21]) have been linked to better health outcomes. For more information on polyphenols follow this link.

On https://gutbites.org/wp-content/uploads/2023/05/Slides-For-Website.pdf, you give fruit smoothies a score of 84, which may reflect their nutritional content, but isn’t it also true that smoothies are basically sugar bombs because all their sugar is available as free sugar, and are therefore not as healthy as they seem?
You raise an excellent point. If you type in “fruit smoothie” you’ll see a range of scores (84 to 45) as determined by the algorithm and based on the specific nutrients and their ratios as you surmise. The score of 84 is in part being driving by the high fiber (glycemic index mitigating) content and added protein of that particular smoothie. The algorithm does not currently take into account food structure, which some literature has shown impacts nutrient absorption. There is active debate on the impact of blending food. It is interesting to note that foods that have concentrated components of fiber (i.e. skin or seeds) can actually have an improvement in glycemic index with blending. Below is one of a handful of papers that might support this idea. Thanks for your astute comment! https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9657402/
Will there be a way for us to be able to input food items with the nutritional facts if it doesn’t show on your list of foods? I’m in Australia so a lot of foods I use don’t show.
Great question. The app will indeed have the option to input nutritional facts for products not in the database.
Please let us know when the app is available in the app store
Will absolutely let you know. Thanks for your note.
Absolutely outstanding tool. Very well designed infographics. Minor translation and vocabulary issues from American English to Australian English but this will only slightly slow down use.
Gage, really appreciate your positive feedback! Glad you’ve found the calculator useful.
What a great way to see how healthy you are eating.
Interesting and looks easy to use. Also makes you think.
Very cool tool!
Awesome!
Love this, so simple but practical!
The above calculator demonstrates the power of the algorithm. The above app will make it practical. Still a work in progress and welcome your feedback.
Is that app available in the Apple app store?
Hi Mark, Thanks for the question. Not just yet, but working on it. Will send a note out when it is available. In the meantime, you can try the online calculator as an appetizer. The app will have added the functionality of allowing you to scan grocery store items and combine foods in specific proportions. Stay tuned! Best, Dr. D
Agree with others this is simple, practical, and helpful.
One technical nit: I have tried the app in both Android and Apple platforms and in both I have the same issue. Some of the food descriptions have indication there is more to the description (… at the end) and neither platform allow me to see the entire food description. E.g., Value of 83 “Lettuce, salad with avocado, tomato, and/o…”
I have been using the app all day to develop menu for the week.
Thanks for the work on your part.
Thanks for the feedback. Glad you’ve found it useful! Try turning your phone sideways or resizing the window on a computer screen and those longer descriptions should be visible. Please let me know if this doesn’t work, and of course would love to hear about some of those meals you’ve planned.
