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

Brassica seed storage protein

Rapeseed refers to seed proteins from Brassica plants commonly used in oils and food ingredients. Measuring IgA and IgG antibody responses to rapeseed proteins helps reveal whether the immune system recognizes these dietary proteins and can clarify patterns related to digestive, skin, or systemic symptoms.

About Rapeseed

Overview and History

Rapeseed comes from Brassica species (including Brassica napus) in the Brassicaceae family. Biochemically, the seeds are rich in storage proteins such as cruciferin (11S globulin) and napin (2S albumin), alongside oils, minor lectins, and related peptides that can remain in less-refined products. Domesticated for oil and food use for centuries, modern breeding produced low‑erucic “canola” varieties. In a testing context, rapeseed proteins are monitored because they are stable seed storage proteins that can serve as antigens for the immune system and thus are relevant when mapping food-related immune patterns.

Interpreting Highs and Lows

Elevated IgA or IgG responses to rapeseed proteins indicate measurable immune recognition of those seed-derived proteins. This may reflect repeated or recent dietary exposure, mucosal involvement if IgA is raised, or cross-reactivity with related Brassica foods; processing (cold‑pressed versus highly refined oils) can also affect protein presence and measured responses. Low or absent responses suggest little measurable immune activity to rapeseed proteins, which could result from low exposure, immune tolerance, or removal of proteins during refinement. All findings gain meaning when interpreted alongside other Food Zoomer markers and the clinical and dietary context.

Featured Test

Rapeseed is included because its proteins are common in the food supply and can produce measurable IgA/IgG signals. Testing rapeseed evaluates immune recognition of seed storage proteins and potential cross-reactivity with other cruciferous foods, helping providers map mucosal versus systemic responses and refine personalized dietary planning within the broader Food Zoomer report.

Rapeseed FAQs

What is Rapeseed and why is it important?

Rapeseed is the seed of Brassica plants used for oils and food ingredients; its seeds contain stable storage proteins. Those proteins can be detected by the immune system in some people. Testing for rapeseed antibody responses helps identify whether these seed proteins are part of a pattern of immune activity linked to symptoms.

What does it mean if my Rapeseed levels are low?

Low rapeseed antibody levels mean there is little measurable IgA or IgG response to rapeseed proteins. This can reflect limited dietary exposure, immune tolerance, or use of highly refined oils that lack protein. Low levels don’t rule out other food-related immune patterns and should be considered with the rest of your Food Zoomer results and diet history.

What does it mean if my Rapeseed levels are high?

High rapeseed antibody levels indicate measurable immune recognition of rapeseed proteins and may reflect recent or repeated exposure, mucosal involvement if IgA is elevated, or cross-reactivity with other Brassica foods. Elevated results are most informative when interpreted with symptoms, dietary patterns, and other markers from the Food Zoomer panel.

Why is Rapeseed included in the Food Zoomer?

Rapeseed appears in the panel because its proteins are common in food ingredients and can elicit measurable immune responses. Measuring rapeseed helps providers detect mucosal versus systemic reactivity and potential cross-reactivity with other cruciferous foods, improving the accuracy of dietary interpretation and personalized nutrition planning.
