About Almond
Overview and History
Almond is the edible seed of Prunus dulcis and belongs to the rose family (Rosaceae). Biochemically, almond contains storage proteins, lipid-associated proteins (like oleosins), and smaller peptides that can be antigenic—meaning the immune system can form antibodies against them.
In food immunology, almond proteins have been studied as examples of plant storage proteins that elicit measurable antibody responses in some people. In the Food Zoomer, almond is assessed at the protein and peptide level to capture detailed immune recognition patterns rather than a single aggregate measure.
Interpreting Highs and Lows
Elevated IgA or IgG responses to almond generally indicate measurable immune recognition of almond proteins. Higher IgA may point toward mucosal immune activity in the gut, while higher IgG suggests systemic antibody exposure; both can be associated with patterns of prior exposure, immune memory, or food-driven immune signaling.
Low or absent measurable antibodies to almond suggest little or no current immune recognition, which can reflect tolerance, limited recent exposure, or absence of a measurable antibody response. Interpretation depends on the full Food Zoomer profile, isotype patterns, symptom history, and clinical context.
Featured Test
Almond is included because it’s a common dietary tree nut with distinct protein and peptide markers; measuring IgA and IgG responses to almond helps identify whether immune activity clusters around nuts. This contributes to personalized nutrition planning by clarifying almond’s role within broader food-reactivity patterns assessed by the Food Zoomer.
