Eat for the genes you actually have.
GenomEats reads the raw DNA file you already have from 23andMe or AncestryDNA and turns a handful of well-studied variants into plain advice about food and drink. The analysis runs on your iPhone, so your genome never reaches us.
The iPhone app is in development.

Five genes with real evidence behind them
Each of these variants changes what a specific food or drink does in your body, and each has been studied well enough to say so plainly. Every report links to the research it is built on.
| Trait | What you find out |
|---|---|
| LactoseLCT / MCM6 · rs4988235 | Whether you likely still make lactase as an adult, and which dairy foods tend to sit best if you don't. |
| GlutenHLA-DQ2.5 / DQ8 | Whether you carry the immune genes that celiac disease requires. A negative result makes celiac very unlikely; a positive one is common and is not a diagnosis. |
| AlcoholALDH2 · rs671 | Whether you carry the variant behind alcohol flush, and why that makes drinking less a matter of comfort and more a matter of risk. |
| CaffeineCYP1A2 · rs762551 | Whether you are likely a faster or slower caffeine metabolizer, and a sensible ceiling for coffee if you are slow. |
| IronHFE · rs1800562, rs1799945 | Whether you carry the HFE variants linked to iron overload, which supplements to skip, and when to ask a doctor for an iron panel. |
Your genome stays on your phone
Genetic data is permanent and it describes your relatives as well as you. GenomEats was designed so there is nothing to leak: the file is read, interpreted and stored on your device.
On your iPhone
Your raw DNA file is opened, the five variants are read and your food advice is written. All of it stays in the app.
On GenomEats servers
No DNA file, no genotypes, no results. There is nothing about your genome here to breach, sell or hand over.
What we leave out
Plenty of DNA diet products sell certainty the research does not support. These are the common ones GenomEats skips, and why.
- Weight-loss diets matched to your DNAIn a year-long trial of 609 adults, a genotype pattern sold for this purpose did not predict who did better on low-fat or low-carb.
- MTHFR supplement plansMedical geneticists recommend against routine MTHFR testing, and the result does not change standard folic acid advice.
- Scores stitched from hundreds of weak variantsIf a gene's effect on food is too small to explain in a sentence, it does not belong in your grocery list.
Questions
Does GenomEats upload my DNA?
No. The analysis runs on your iPhone. Your raw DNA file, your genotypes and your results are never sent to GenomEats servers.
Which DNA tests does it work with?
GenomEats reads the raw data file you can download from consumer DNA services such as 23andMe and AncestryDNA. You do not need a new test.
Is GenomEats a medical test?
No. It explains what well-studied variants mean for food and drink. It does not diagnose anything. For celiac disease and hemochromatosis in particular, a genetic result is a reason to talk to a clinician.
Can my DNA tell me the best diet for weight loss?
The evidence says no. In the DIETFITS trial of 609 adults, a genotype pattern marketed for exactly this purpose did not predict who lost more weight on a low-fat or a low-carb diet.
Why does GenomEats cover so few genes?
Because only a handful of variants have a clear, reproducible link to a specific food. Adding weaker ones would make the reports longer and less true.
When can I use it?
GenomEats is in development for iPhone. The science pages on this site are available now.
