What does the Clarity Checker do?

Clarity Checker lets you search any food ingredient, supplement, or additive and instantly see 15+ safety dimensions including lactation safety, histamine and DAO status, CMPA cross-reactivity, ADHD risk flags, heavy metal risk, glycemic impact, allergen class, and more — all backed by evidence-graded data from peer-reviewed sources.

Is Clarity safe to use while breastfeeding?

Clarity is an informational database tool, not medical advice. It reports evidence-graded safety classifications for ingredients based on sources like LactMed, InfantRisk, and peer-reviewed literature. Always discuss dietary changes with your healthcare provider or IBCLC.

How many ingredients does Clarity cover?

Clarity's database currently covers 1,300+ ingredients including foods, supplements, botanicals, food additives, preservatives, and common formula ingredients. Each entry is graded with an evidence tier (Gold, Silver, or Bronze) based on source quality.

Can I scan a barcode with Clarity?

Yes. The Clarity Barcode Scanner lets you scan or enter any UPC/EAN barcode. It pulls the product's ingredient list from Open Food Facts, then checks every ingredient against the Clarity database for safety signals including histamine, DAO inhibition, CMPA risk, and ADHD flags.

What is a histamine liberator?

A histamine liberator is a substance that triggers your body's mast cells to release stored histamine, even if the food itself is low in histamine. Common examples include citric acid, strawberries, and certain spices. Clarity flags histamine liberators separately from high-histamine foods so you can identify both triggers.

What does DAO inhibitor mean?

DAO (diamine oxidase) is the enzyme that breaks down histamine in your gut. A DAO inhibitor blocks this enzyme, causing histamine to build up even from normal foods. Clarity flags DAO inhibitors so breastfeeding parents with histamine sensitivity can identify hidden triggers affecting their baby.

Does Clarity check for heavy metals and contaminants?

Yes. Clarity's barcode scanner checks products against a contaminant database with 174 lab-tested products. This includes brand-specific arsenic, lead, cadmium, mercury, and glyphosate levels from Florida Department of Health (2026), Environmental Working Group, and Healthy Babies Bright Futures. Scan any infant formula, baby food, cereal, bread, or candy and see contaminant alerts alongside ingredient safety data.

Does Clarity check for glyphosate in food?

Yes. Clarity includes glyphosate residue data from EWG testing (2022-2023) and Florida DOH bread testing (2026). The scanner shows glyphosate levels in ppb and flags products exceeding EWG's 160 ppb health benchmark. Brands tested include Quaker, General Mills, Nature's Own, and Dave's Killer Bread.

What foods are safe for histamine intolerance?

Clarity checks 1,595 ingredients for histamine content (measured in mg/kg), DAO enzyme inhibition, and putrescine levels. Low-histamine foods include most fresh fruits (except citrus and strawberries), fresh vegetables (except spinach, tomatoes, eggplant), fresh meat and fish, and most grains. Fermented foods, aged cheese, cured meats, and alcohol are typically high-histamine.

Can food trigger rosacea flares?

Yes. Common rosacea food triggers include red wine (histamine + vasodilation + DAO inhibition), aged cheese, chocolate (cinnamaldehyde), spicy foods (capsaicin), and fermented foods. Clarity checks 1,595 food ingredients and 92 skincare ingredients for rosacea-relevant triggers including histamine content, vasodilator status, and mast cell activation.

What foods should I avoid with MCAS?

MCAS patients should be cautious with high-histamine foods, histamine liberators, and DAO inhibitors. Clarity flags 268 MCAS triggers across 1,595 ingredients. Common triggers include fermented foods, alcohol, citrus, tomatoes, shellfish, and certain food additives. The database includes measured histamine concentrations from 12 published studies.

Is my probiotic safe for histamine intolerance?

Some probiotic strains produce histamine. L. reuteri (found in BioGaia) produces 8,510 ng/mL histamine in laboratory testing. Of 172 catalogued histamine-producing bacterial strains, 17 are sold commercially as probiotics. Bifidobacterium strains (B. longum, B. lactis, B. breve) are generally histamine-safe. Use Clarity to check any probiotic strain.

What foods trigger hidradenitis suppurativa?

HS dietary triggers include dairy (especially whey protein), brewer's yeast (87% flare rate in one study), high-glycemic foods, and nightshades. HS is also connected to mast cell activation, linking it to histamine and DAO pathways. Clarity flags HS-relevant triggers across 1,595 ingredients.

Can diet affect asthma symptoms?

Yes. A randomized controlled trial (Vassilopoulou 2020) showed that a high-histamine diet significantly reduced peak expiratory flow in asthmatic children (p=0.0006). Histamine contracts bronchial smooth muscle. Sulfites in wine and dried fruit are also established asthma triggers. Clarity flags 89 asthma trigger ingredients.

What is a DAO inhibitor?

DAO (diamine oxidase) is the enzyme that breaks down histamine in your gut. DAO inhibitors are foods or substances that block this enzyme, causing histamine to accumulate even if you didn't eat high-histamine food. Common DAO inhibitors include alcohol, certain teas, and energy drinks. Putrescine-rich foods (oranges 117.6 mg/kg, green peas 56.7 mg/kg) also compete with histamine for DAO clearance.
