Your gut microbiome eats what you eat. Gut health comes down to two things the research backs most: fiber, about 30 grams a day, and plant variety, 30 different plants a week. Feed Your Gut makes both visible from a single photo, so better choices stop being guesswork.

Variety and fiber, measured.

  1. 30+1

    different plants a week

    went with a more diverse gut microbiome than 10 or fewer, across more than 10,000 people in the American Gut Project.

  2. 25–29g2

    of fiber a day

    was where the lowest risk of heart disease, stroke, type 2 diabetes and colorectal cancer showed up, across 185 cohort studies and 58 trials.

  3. 95%3

    of Americans

    fall short of the recommended fiber intake. Most adults eat around 15 to 16 grams a day.

  4. 194

    inflammation markers

    went down in a Stanford trial when healthy adults ate more fermented foods for ten weeks. Microbiome diversity went up.

No weighing, no searching a database, no counting. Point the camera at your plate and Feed Your Gut does the rest.

    Snap

    Take a photo, scan a barcode or type a line like “sugar free granola with kefir”. What you type stays exactly as you wrote it.

    Fiber in grams, every plant identified, ferments told apart and a gut score from 0 to 100, explained in plain language.

    One specific suggestion for next time, and a week view that shows your plants climbing toward 30 and your fiber toward 30 g.

Everything your gut cares about.

Built around the signals the research actually supports. Nothing you have to weigh, nothing that moralizes your food.

A gut score from 0 to 100

Every meal starts at 40. Fiber, plant variety and gut fuel like legumes, whole grains and ferments raise it. Ultra-processed, fried and very sugary food lowers it. The rules are public.

Fiber in grams, not in vibes

Real grams per meal and across the day, measured against the 30 g most European guidelines recommend. Not low, medium or high.

30 plants a week, counted for you

Every different plant counts once per week, herbs, spices, seeds and grains included. The count fills itself as you scan.

Ferments, told apart properly

Live cultures in kefir, yogurt or fresh kimchi count as probiotic. Pasteurized sauerkraut or baked sourdough count as fermented, not live.

An anti-inflammatory read-out

A separate scale from −5 to +5 for omega-3, olive oil, polyphenols and spices on one side, processed meat, deep frying and sugar load on the other.

A ten-second gut check‑in

How your gut feels, bloating, energy and stress. Over the weeks you see what your food has to do with it, plus streaks and weekly challenges to keep going.

A score you can actually read.

No black box. Every meal starts at 40 and moves for reasons you can see. Two meals, the same rules:

Illustrative examples. The analysis applies the same rules with judgment, so a real scan can land a few points either way. Your daily score adds up the whole day, and one heavy meal never erases a good morning.

Calorie apps were built for the scale. Feed Your Gut is built for the trillions of microbes that live on the part of your food you cannot digest yourself.

Not another calorie counter.
Feed Your Gut Typical calorie counter

Sometimes. Protein and calories still ride along in Feed Your Gut as neutral estimates. They never change the gut score.

What is gut health and how do I improve it?

Gut health means a diverse, well-fed community of gut microbes. The best-supported ways to improve it are about 30 grams of fiber a day, 30 different plants a week and fermented foods with live cultures, like kefir or yogurt. Feed Your Gut tracks all three from a photo of your meal. This is general information, not medical advice.

What is Feed Your Gut?

Feed Your Gut is a gut health app for iPhone. You snap a photo of a meal, scan a barcode or type what you ate. The app shows the fiber in grams, counts every different plant toward a goal of 30 a week and scores the meal from 0 to 100 for gut health, with one specific suggestion for next time.

How is the gut score calculated?

Every meal starts at 40. Fiber adds 4 points per gram, up to 30. Gut fuel adds up to 30 more: live probiotic foods +14, other fermented foods +8, legumes +10, whole grains +8, and nuts, seeds, polyphenols and prebiotics +5 each. Each whole plant adds 3, up to 12. Ultra-processed food and processed meat subtract up to 25, deep-fried food 20, added sugar 15 and refined grains 10, weighted by how much of the meal they make up. The result is clamped between 0 and 100.

Why 30 plants a week?

In the American Gut Project, published in mSystems in 2018, people who ate more than 30 different plant types a week had more diverse gut microbiomes than people who ate 10 or fewer. Diversity mattered more than the diet label, vegan or omnivore. Vegetables, fruit, legumes, whole grains, nuts, seeds, herbs and spices all count, and each plant counts once per week.

How much fiber should I eat per day?

Most adults should aim for about 30 grams a day. That is the recommendation of the German Nutrition Society (DGE) and the UK’s SACN. US guidelines give 14 grams per 1,000 calories, which works out to roughly 25 grams for women and 38 grams for men. A 2019 Lancet meta-analysis found the lowest disease risk at 25 to 29 grams a day or more.

Is Feed Your Gut a calorie counter?

No. The headline numbers are fiber, plant diversity and the gut score. Protein and calories are shown as neutral estimates for people who want them, and they never change the gut score.

Do I need an account?

No. There is no sign up. Your history stays on your iPhone and in your own iCloud.

What happens to my meal photos?

A photo goes to our server for the analysis and is deleted right after. Your meal history itself lives on your iPhone and in your own iCloud. The privacy policy has the full details.

How much does it cost?

Feed Your Gut is a subscription app, so scanning needs an active plan. You can choose a yearly, monthly or weekly plan, and the yearly plan starts with 3 days free. Prices are shown in the app before you confirm, and you can cancel anytime in your Apple account settings.

Is Feed Your Gut available on Android?

Not yet. Feed Your Gut is currently available for iPhone, in English, German and Spanish.

Is this medical advice?

No. Feed Your Gut is not a medical device and does not diagnose or treat any condition. If you have ongoing digestive symptoms, a diagnosed condition such as IBS or IBD, or a special diet, talk to a doctor or registered dietitian.
