foodZipper analyzes a curated set of nutritionally relevant variants across methylation, neurotransmitter, detox, and nutrient-processing pathways — including MTHFR (C677T, A1298C), COMT (V158M, H62H), MAO-A, VDR, MTR, MTRR, SOD2, NAT2, BHMT, SHMT1, and others.
You can view a real sample report at foodzipper.com/sample-report.html. The report includes your gene variants, what you may be feeling, a daily food and lifestyle protocol, the science behind each recommendation with links to published research, and a full panel of all tested SNPs.
foodZipper matches gene variants to nutrient needs based on peer-reviewed biochemistry — each gene card links directly to published research on PubMed and PMC. The SNP-to-nutrient-to-food relationships are well-established in the scientific literature. foodZipper does not predict disease or make clinical claims. It shows you what your enzymes need and which whole foods provide it. You can check every source yourself.
No. Your DNA file is processed locally on your device and is never uploaded, stored, or transmitted. There is no server, no database, no cloud storage, no cookies, no analytics, and no tracking of any kind.
Yes. All processing happens locally on your device. There is no server to breach, no database to hack, and no account to compromise.
No. foodZipper never sees your data. There is nothing to sell because nothing is collected.
That is your choice — but understand the tradeoff. When you upload a file to any AI tool, that file leaves your device and reaches a third-party server. foodZipper processes everything locally — your DNA file never leaves your browser. If you want AI to help explain your results, a safer approach is to use foodZipper first, then share the finished report — not your raw DNA file — with an AI tool.
MTHFR is an enzyme that converts dietary folate into its active form. Common variants like C677T and A1298C can reduce enzyme activity, which may affect energy, mood, focus, and sleep. Natural folate from whole foods like spinach, lentils, and asparagus supports this pathway.
Foods rich in natural folate support MTHFR function: lentils, chickpeas, black beans, spinach, asparagus, brussels sprouts, broccoli, and avocado. Riboflavin (B2) is also an MTHFR cofactor — found in eggs, salmon, sardines, and mushrooms. Food-sourced folate is generally preferred over synthetic folic acid for those with MTHFR variants.
COMT clears dopamine in the prefrontal cortex — the brain region responsible for focus, decision-making, and stress response. The V158M variant slows this clearance. Magnesium is a required cofactor — whole food sources include pumpkin seeds, spinach, dark chocolate, cashews, and almonds.
Some nutrient pathways involved in focus, mood, and stress response are influenced by genetic variation. foodZipper highlights whole-food options that may support those pathways based on your specific gene variants. This is for personal wellness exploration only — not medical advice or treatment.
Certain nutrients serve as cofactors for enzymes involved in dopamine regulation and neurotransmitter clearance — processes directly related to focus and attention. For example, magnesium is required by COMT, and riboflavin (B2) is required by MAO-A. Genetic variants in these enzymes can affect how efficiently they work. foodZipper identifies your variants and matches them to whole foods that provide the specific cofactors those enzymes need. This is for personal wellness exploration — not a substitute for professional evaluation or treatment.
Caffeine increases dopamine and norepinephrine activity. If you carry variants in COMT or MAO-A that slow neurotransmitter clearance, caffeine can amplify what is already building up — leading to heightened anxiety, irritability, or restlessness. foodZipper flags these variants and explains the underlying pathway so you can make informed choices about caffeine intake.
Yes. Serotonin converts to melatonin — your sleep signal. That conversion depends on nutrients like B6 and folate, and can be influenced by gene variants such as MTHFR A1298C, which may affect BH4 recycling needed for serotonin production. Tryptophan-rich foods like turkey and chicken paired with complex carbs in the evening can support this pathway. foodZipper includes sleep-relevant findings in your report when your variants are involved.
Yes. Genetic variants can affect how efficiently your body processes certain nutrients. For example, MTHFR variants affect folate metabolism, COMT requires magnesium, and MAO-A depends on riboflavin (B2). Nutrigenomics studies how these gene-nutrient interactions work. foodZipper applies this science by matching your variants to whole food sources.
Nutrigenomics is the study of how genetic variation affects the way your body responds to nutrients — how gene variants influence enzyme activity, nutrient metabolism, and which foods best support your individual biochemistry.
Both are variants in the MTHFR gene but affect different processes. C677T reduces folate conversion — homozygous carriers may have up to 70% reduced activity. A1298C may affect BH4 recycling, needed for serotonin, dopamine, and melatonin production. Having both (compound heterozygous) is considered more significant than either alone.

Most DNA wellness tools end with a supplement recommendation. foodZipper recommends whole foods only — no pills, no powders, no affiliate links to supplement stores. The cofactors your enzymes need come from food. That is the core philosophy.
Most DNA nutrition tools cost $100 to $250, process your data on their servers, and give you a branded diet label or supplement list. foodZipper is free, processes everything locally on your device, recommends whole foods only, and links every recommendation to published research you can verify yourself. No account, no cloud, no black box.
Yes — and with your doctor, naturopath, dietitian, or any healthcare provider. Your report is saved as an HTML file on your device and it is yours to share however you choose. foodZipper builds the report — it does not interpret or diagnose. AI tools like Claude or ChatGPT can help explain your results in plain language. A licensed provider can use them as a starting point for clinical analysis. The interpretation is theirs. The data is yours.
foodZipper recommends whole foods only — no supplements. The cofactors that MTHFR and related enzymes need are all available in food. Always consult a healthcare provider before making changes to your health routine.
Start with the Your Protocol tab — it organizes your food, movement, and mind practices into a daily timeline from morning to evening. Focus on the foods that appear most often across your gene cards. Share your report with your healthcare provider if you want clinical guidance. Track what you notice over the first few weeks — energy, mood, focus, sleep. Small consistent changes tend to show results before big overhauls do.
Your gene variants do not change — your report will always be accurate for the SNPs it covers. However, foodZipper is actively expanding its gene panel. As new genes are added, uploading your file again will give you a more complete picture. Bookmark the site and check back periodically for updates.
Yes, if you have your child's raw DNA data file from AncestryDNA, 23andMe, or MyHeritage. The same privacy protections apply — the file never leaves your device. foodZipper provides whole-food recommendations only, which are generally appropriate for children. Always consult your child's pediatrician before making significant dietary changes, especially for children with allergies, medications, or existing health conditions.
