Chickpeas

Overview

Chickpeas are legumes providing plant protein, prebiotic fiber, folate, magnesium, and B6, supporting gut health and neurotransmitter synthesis. Chickpeas have a DIAAS score of 64-69, indicating they are methionine-limited and should be paired with grains for complete amino acid profile. Chickpeas are listed as sources for magnesium, iron, zinc, and B6, all critical cofactors for neurotransmitter synthesis.

Preparation Notes

• Soak and cook thoroughly to reduce phytates and improve mineral bioavailability; soaking and sprouting reduces phytates in legumes/grains, improving non-heme iron and zinc bioavailability
• Pair with grains for complete amino acid profile; combine with grains like barley or oats for amino acid complementarity
• Pair with vitamin C to enhance iron absorption, with studies showing up to a fourfold increase when consumed together
• Part of grain-legume complementarity strategy
• Legumes such as lentils and chickpeas provide complex carbs and fiber
