Kefir scores 98 out of 100 and sits in the excellent band. Among the lower-risk choices for most people with gout, and often carries protective nutrients.
Penalties took 7.6 points off a starting score of 100, and protective factors added 6.1 back (trimmed from 11.3: bonuses can offset at most 80% of the penalties). Every factor is listed in full below.
Scores run 0–100, where higher means more gout-friendly on average. They reflect relative ranking across foods, not a personal risk level. The same food can suit one person and not another, so use the score as a starting point for a conversation with your clinician.

Each row shows the points a factor moved, what drove it, and the studies behind its weight.
- +10Flare + long-term
Dairy ProtectionFlare + long-term
Low-fat dairy protein lowers urate (the orotic acid and casein effect), earning the full protective bonus.

- -6Long-term
Nutrient GapsLong-term
Provides meaningful amounts of only 2 of the 5 protective nutrient groups (vitamin C, fiber, omega-3, magnesium and folate).
Evidence: Choi HK 2009, Arch Intern Med · Juraschek SP 2016, Arthritis Rheumatol · Zhang M 2019, Arthritis Rheumatol
- -1.1Long-term
SodiumLong-term
38 mg of sodium per 100 g, scaled 2.4x for the typical portion.
Evidence: FitzGerald JD 2020, Arthritis Care Res
- +0.7Long-term
MagnesiumLong-term
12 mg of magnesium per 100 g, scaled 2.4x for the typical portion.
Evidence: Li X 2015, BMJ
- -0.5Long-term
Saturated FatLong-term
0.6 g of saturated fat per 100 g, scaled 2.4x for the typical portion. Discounted 75% because dairy fat shows a weaker association.
Evidence: Juraschek SP 2016, Arthritis Rheumatol · Yokose C 2021, Curr Opin Rheumatol
- +0.4Long-term
FolateLong-term
18 µg of folate per 100 g, scaled 2.4x for the typical portion.
Evidence: Lyu LC 2017, Am J Clin Nutr
- +0.2Long-term
Vitamin CLong-term
0.8 mg of vitamin C per 100 g, scaled 2.4x for the typical portion. Vitamin C helps the kidneys excrete urate.
