What is Strawberry and Why Does the Food Zoomer Test for It?

Plant food protein antigen

Strawberry is a fruit-derived set of proteins and peptides that can be recognized by the immune system. Measuring IgA and IgG responses to strawberry proteins helps indicate whether reactivity is localized at the gut lining or reflects broader systemic immune engagement.

About Strawberry

Overview and History

Strawberry (Fragaria × ananassa) is a member of the Rosaceae family. The fruit contains multiple small proteins and peptides—including PR proteins, profilins, and lipid-transfer proteins—that play roles in plant defense and fruit biology and can serve as targets for human antibody recognition. Clinical and laboratory research has characterized these protein families as common sources of cross-reactive immune recognition among fruits and pollens. Modern assays detect antibodies against whole‑fruit extracts and discrete peptide fragments, and peptide-level testing can help pinpoint specific immune targets and clarify cross-reactivity patterns.

Interpreting Highs and Lows

Elevated IgA or IgG responses to strawberry indicate measurable immune recognition of strawberry proteins and suggest prior exposure with an antibody response; IgA-dominant results tend to reflect mucosal/gut-associated activity while IgG-dominant results are more suggestive of systemic immune engagement. Low or absent antibody signals suggest no detectable immune recognition at the time of sampling, recent avoidance of the food, or that other foods or components are driving immune patterns. Interpretation should always be made in the context of the full Food Zoomer panel and the individual’s symptom and exposure history.

Featured Test

Strawberry is included because it’s a common dietary fruit with protein families that frequently produce detectable antibody responses. The marker evaluates IgA and IgG reactivity to whole-extract and peptide components, helping reveal whether fruit/berry proteins contribute to clustered immune patterns and informing personalized dietary planning and follow-up testing.

Strawberry FAQs

What is Strawberry and why is it important?

In the Food Zoomer, Strawberry represents the proteins and peptides found in the fruit that the immune system may recognize. Identifying antibodies to strawberry helps show whether the immune system has been exposed to these components. That information contributes to seeing broader food-related immune patterns and can help providers interpret possible links between diet and symptoms.

What does it mean if my Strawberry levels are low?

Low or undetectable strawberry antibody levels mean there is no measurable IgA or IgG response at the time of testing. This can reflect true lack of immune recognition, recent avoidance of strawberries, or timing of exposure relative to the blood draw. Low levels are one piece of the overall Food Zoomer pattern and are best interpreted alongside other markers and clinical history.

What does it mean if my Strawberry levels are high?

Higher strawberry antibody levels show measurable immune recognition of strawberry proteins. Depending on whether IgA or IgG is dominant, this can suggest more mucosal (gut) versus systemic engagement. Elevated results suggest an association between strawberry exposure and immune activity but require integration with other panel results and symptom history to determine relevance.

Why is Strawberry included in the Food Zoomer?

Strawberry is commonly consumed and contains protein families that can produce antibody responses and cross-react with other plant proteins. Measuring it with dual IgA/IgG and peptide-level precision helps providers detect clustered reactivity (for example, fruit/berry patterns), distinguish mucosal versus systemic signals, and prioritize foods for targeted dietary assessment and follow-up.
