Why oxalates are being discussed in gadolinium illness
Oxalates (oxalic acid and related compounds) are natural molecules found in many foods. In the gadolinium context, some clinicians and researchers have raised concern that oxalates may interact with retained gadolinium and potentially contribute to nanoparticle formation in tissues.
This does not mean every person with gadolinium exposure must eliminate all oxalates. It means oxalate burden may be one potentially modifiable factor to review with your clinician, especially if symptoms are persistent or severe.
Gadolinium + Oxalates = Nanoparticles
Dr. Brent Wagner's research group at the University of New Mexico reported a mechanism suggesting oxalic acid may help gadolinium precipitate and form nanoparticles in human tissues. This mechanistic finding is a key reason many patients are advised to limit high-oxalate intake.

If your clinician suspects a high-oxalate state, a temporary lower-oxalate approach may be considered. Common examples often discussed include spinach, rhubarb, many nuts, chocolate, and some berries.
Top very high foods to avoid first
Based on the oxalate values you shared, these are some of the highest-priority foods to reduce first:
- Spinach, cooked (1/2 cup): 755 mg
- Spinach, raw (1 cup): 656 mg
- Rhubarb (1/2 cup): 541 mg
- Rice bran (1 cup): 281 mg
- Buckwheat groats (1 cup cooked): 133 mg
- Almonds (1 oz / 22 kernels): 122 mg
- Baked potato with skin (1 medium): 97 mg
- Cocoa powder (4 tsp): 67 mg

Nutrient depletion: Higher oxalate burden may bind minerals in the gut and reduce availability of key nutrients in susceptible individuals.
Inflammation: Oxalate stress may contribute to local or systemic inflammatory signaling in sensitive people.
Calcium oxalate crystal accumulation: Oxalates can bind calcium and potentially form calcium oxalate crystals, which may irritate tissues in some cases.

MCAS and high histamine foods to watch
Mast cell activation syndrome (MCAS) and high histamine foods are another area to consider when managing gadolinium-related symptoms. Many people with gadolinium sensitivity also have histamine intolerance or MCAS, and certain foods can trigger mast cell release. If you suspect this overlap, review our guide on DNA, histamine, and MCAS.
