Garlic

Garlic

Overview

Garlic provides allicin (when crushed), sulfur compounds for glutathione synthesis, and prebiotic fiber supporting gut health and antioxidant defenses. Sulphur-containing vegetables that provide glutathione precursors (e.g., broccoli, Brussels sprouts, garlic, onions) support NAD+ availability, glutathione synthesis, and mitochondrial health.

Within the BRAIN Diet framework, garlic is part of the allium family with prebiotic benefits [1][2].

Food Context

Synergies

  • Part of diverse plant food strategy; dietary diversity (≥30 plant foods per week) supports microbial richness and resilience

Preparation

  • Crush or chop to activate allicin formation; allicin is formed when garlic is crushed
  • Allow to sit 10 minutes after crushing before cooking to maximize allicin formation
  • Cooking reduces allicin but may enhance other compounds
  • Sulphur-containing vegetables that provide glutathione precursors support antioxidant defenses

Essential Amino Acid Profile

Garlic contribute plant protein. Pair with complementary protein sources (e.g. grains and legumes) for a balanced essential amino acid profile.
