Food Allergies · Gluten and Dairy Sensitivities · Histamine Intolerance · Other Sensitivities
This report reads your DNA and sorts every result into one of five plain-language groups, so you can see at a glance what deserves attention and what does not. Nothing here is a diagnosis. A flagged result means your genetics place you above or below the average person for that trait — a reason to ask a question, not a reason to worry.
These are ordered by how closely they relate to your flagged results — not generic health advice. Marrow does not prescribe, dose, or tell you to take anything. Diet and lifestyle changes are listed first because they are yours to make. Anything you would swallow is listed separately, by name only, as something to raise with a clinician who knows your history and your medications.
Begin by removing foods you suspect might be causing adverse reactions for 2-3 weeks.
Identify foods that trigger negative reactions in your body, such as digestive issues, allergies, or headaches, and eliminate them from your diet entirely.
Aim to include foods like eggs, dairy products (such as cheese, yogurt, and milk), and soy-based foods in your meals regularly.
These came up in the research behind your flagged results. They are listed by name so you can ask about them. Marrow is not recommending them, and gives no dose. Supplements interact with prescription medication and with each other — that conversation belongs with your clinician.
Of the 22 results in this package, these 4 came back furthest from the population average. Each one below explains what it is, where you sit, and which report it came from. Start here.
Key Takeaways: Up to 80% of differences in people's chances of having food allergies may be attributed to genetics.
Many allergies come and go through childhood, but common ones that linger into adulthood include nuts, seafood, milk, and eggs.
Reducing risk for allergies involves avoiding the various food triggers.
Named only. Marrow gives no dose and does not recommend these.
About 3 million people in the U.S. have a nut allergy.
Risk factors involve contact with peanuts.
Verify food content in restaurants, and read all food packaging labels to minimize risk.
Egg allergies are relatively common, especially in children, and can be very severe.
A person usually develops a reaction to one or more egg white proteins.
Luckily, the allergy often fades with age [R, R].

The CNR1 gene codes for cannabinoid receptor 1 (CB1), which binds the cannabinoids in the brain, gut, and other tissues.
Gut Inflammation SNPs in this gene can make you more or less susceptible to inflammatory bowel disease (IBD), and people with risk alleles are likely to have worse IBD than those without.

The remaining results, grouped by what they mean. Every one of these is explained in full — with the genes and variants behind it — in the technical version of this report.
Genetics is a predisposition, not a verdict. The single most useful thing you can do with this document is take it to a clinician and talk through the flagged findings — especially any that line up with symptoms you already have or conditions that run in your family. Nothing here changes: your DNA is the same at 60 as it is today, so this report does not expire.
Genotyping was performed on DNA extracted from a buccal (cheek) swab using a genome-wide array. Results are derived from peer-reviewed genome-wide association data and, where applicable, published clinical guidelines. Each report was scored independently against its own reference set. Percentile figures describe where your result sits relative to a reference population.
This is a laboratory-developed test. It has not been cleared or approved by the U.S. Food and Drug Administration. Genotyping does not detect all variants in the genes assessed; the absence of a flagged result does not exclude risk. Predisposition is probabilistic and is modified by environment, lifestyle, ancestry and family history. Results must be interpreted by a qualified healthcare professional and must not be used alone to diagnose, treat, or alter any medication regimen. Marrow does not recommend, prescribe, or dose any supplement or medication.
