MyFitnessPal for plant-based eaters: an honest critique
Pros
- Largest overall food database; most foods are searchable somehow.
- Excellent barcode scanner for packaged foods (when the SKU is in the database).
- Familiar interface; lowest learning curve for users coming from a generation of fitness culture.
- Free tier is functional for calorie-only tracking.
Cons
- User-submitted plant-food entries are extremely variable: B12, iron, and fortification values are frequently wrong by 20 to 60 percent.
- Multiple entries for the same branded plant milk can disagree on B12 by an order of magnitude.
- No reliable way for the user to distinguish curated from user-submitted entries.
- Iron and zinc tracking on plant foods is unreliable enough to mislead clinical decisions.
- B12 fortification on mock meats is wrong on the majority of audited SKUs.
MyFitnessPal is the most-used calorie tracker in the world and the default app many plant-based eaters reach for first. The site does not recommend it as a primary tool for plant-based eaters who care about micronutrient accuracy, and the rest of this review explains why concretely.
The cons in this review are unusually load-bearing. The pros are real but they describe MFP as a calorie-only tool, which is not what most plant-based eaters need.
Why entry quality is the central issue
MyFitnessPal’s database is enormous because most of it is user-submitted. That model works reasonably well for canonical foods (a banana is a banana) and for packaged foods with clear barcode-mapped SKUs. It works poorly for fortified plant foods, where the per-serving B12, iron, vitamin D, and calcium values depend on the manufacturer, the production run, the reformulation date, and the user who entered the entry.
For plant-based clinical work the result is that searching MFP for “Beyond Burger” returns 30 to 80 entries with widely varying nutrient profiles. The user has no reliable way to identify which entry is current and accurate. Cronometer mitigates this by surfacing USDA-curated entries first. MFP does not.
Database audit results, March 2026
We ran the standard 60-item plant-food audit on MyFitnessPal’s database. Methodology and the same audit on other apps are documented in the Methodology page. Summary:
- Tofu and tempeh. 8 of 8 tofu varieties returned matching search results, but the calcium-set vs nigari-set distinction was preserved in only 3 of the top-ranked entries. For 5 varieties, the top-ranked search hit was a user-submitted entry that did not specify coagulant, which means the calcium value could be off by a factor of three.
- Plant milks. 12 of 12 brands were searchable. For 7 of 12 brands, the top three search results disagreed on B12 by more than 30 percent. For 4 brands, they disagreed on B12 by more than an order of magnitude.
- Mock meats. B12 fortification was wrong on 6 of 10 audited SKUs by more than 30 percent on the top search result. Iron was wrong on 5 of 10.
- Nutritional yeast. The “fortified” vs “unfortified” distinction was unreliable. Several Sari Foods unfortified entries listed B12 values consistent with fortified yeast, which is the worst possible failure mode (an eater believes they are getting B12 when they are not).
- USDA whole foods. Best category. Canonical entries (kale, lentils, chickpeas, etc.) are mostly accurate.
The audit produced a database score of 5.8/10. Pre-2022 versions of MyFitnessPal scored higher because the user-submitted variance was lower; the database has degraded as ad-hoc entries have accumulated.
Iron and B12 specifically
Iron tracking on plant foods is the most clinically dangerous failure mode. A plant-based client with low ferritin who is using MyFitnessPal and reading their iron number as accurate may be getting 20 to 30 percent more or less iron than the app reports. Combined with the bioavailability adjustment that plant-based eaters need to apply anyway, the compounding error makes MFP iron data unsuitable for clinical decisions.
B12 is similarly unreliable on plant foods. A client getting B12 from fortified plant milk, fortified nutritional yeast, and a multivitamin is using three database categories where MFP’s entry quality is weakest. The client may believe they are hitting their B12 target while their actual intake is below target by a meaningful margin.
Where MyFitnessPal still works
MFP is acceptable as a calorie-only tool for plant-based eaters who:
- Already use it and do not want to switch.
- Have no specific micronutrient concerns and are tracking calories for body-composition reasons.
- Are at the very early stage of tracking and are not yet ready to engage with B12, iron, zinc, calcium specifically.
The barcode scanner is genuinely good for packaged foods and the recipe builder works fine for plant-based recipes if the user is patient about ingredient selection.
Premium tier
MyFitnessPal Premium is $19.99/mo, which is more than PlateLens and substantially more than Cronometer Gold. Premium adds macro percentage breakdowns, custom goals, exercise calorie controls, and ad-free use. None of the Premium features fix the database entry quality problem, which is the core issue for plant-based eaters. We do not recommend Premium for plant-based clinical use.
Recommendation
For plant-based eaters who care about micronutrients, do not use MyFitnessPal as the primary tool. Use Cronometer for hand-tracked depth or PlateLens for photo-first workflow. MyFitnessPal is an acceptable calorie-only tool for plant-based eaters who do not need micronutrient accuracy and who already have it installed.
Score: 5.8/10 from a plant-based clinical lens. The score is not lower because the calorie-only and barcode-scanner functionality is real and works.
