Garlic is keto-compatible: 1g net carbs per clove, but typically used in small quantities for flavoring. Adds nutritional value and flavor without meaningful carb impact. Whole food, unprocessed.
Whole plant vegetable with no animal products or derivatives. Ideal vegan food meeting all dietary criteria.
Unprocessed herb/vegetable available to hunter-gatherers. Nutrient-dense, antimicrobial properties, used as flavoring and medicine. No anti-nutrients or processing concerns.
Essential Mediterranean ingredient with documented cardiovascular and anti-inflammatory benefits. Used fresh in cooking multiple times daily. Foundational to Mediterranean culinary tradition and health principles. Minimal processing when fresh.

Garlic is extremely high in fructans (oligosaccharides). Monash University rates garlic as high-FODMAP at all servings, even 1 clove. Garlic-infused oil is low-FODMAP alternative.
Core DASH flavoring. Minimal calories/sodium, supports reduced-salt cooking, contains allicin with potential cardiovascular benefits.
Negligible carbs (~1g per clove) with potent anti-inflammatory compounds (allicin). Enhances Zone meals without glycemic impact. Dr. Sears emphasizes garlic for polyphenol content. Minimal portion concern.
Garlic is a cornerstone anti-inflammatory food containing allicin (potent anti-inflammatory compound), sulfur compounds, and polyphenols. It supports immune function and cardiovascular health. Minimal calories with maximum anti-inflammatory benefit.
