Kidney Beans

-1.3

Kidney beans provide anti-inflammatory fiber, resistant starch, and antioxidants that support metabolic health and reduce chronic disease markers.

Ingredient score breakdown

Soluble and insoluble fiber

-0.6

Dual fiber types stabilize blood sugar, feed beneficial bacteria, and reduce systemic inflammation.

Resistant starch

-0.5

Acts as a prebiotic, producing anti-inflammatory short-chain fatty acids during fermentation.

Antioxidant polyphenols

-0.4

Flavonoids and phenolic acids reduce oxidative damage and inflammatory marker expression.

Lectins (if undercooked)

+0.2

Raw or undercooked beans contain phytohaemagglutinin, which can cause gut inflammation. Proper cooking eliminates this risk.

Why this score

This score is ingredient-based and weighted by DII-inspired evidence. Foods with added sugar, refined starches, and heavy processing trend higher; foods with fiber, omega-3, and polyphenols trend lower.

FODMAP note

High FODMAP due to oligosaccharides. Canned kidney beans rinsed well are lower, limit to 1/4 cup serving.
