A vegan diet excludes all animal products including meat, dairy, eggs, and honey. It focuses on plant-based foods like vegetables, fruits, grains, legumes, nuts, and seeds.

  • Ensure adequate protein from varied plant sources
  • Supplement B12 - it's essential and not available from plants
  • Consider omega-3 from algae-based supplements
  • Iron from plants requires vitamin C for better absorption
  • Plan meals to ensure complete amino acid profiles

What to know about sourdough bread

Genuine long-fermented sourdough is the rare bread that is easier on a sensitive gut. The slow ferment lets bacteria break down 70 to 90 percent of the wheat fructans, which is why Monash rates real sourdough as lower FODMAP than standard wheat bread. But lower FODMAP is not the whole story: sourdough is still wheat, so it contains gluten, and the fermentation actually raises its tyramine, a trigger for migraine and for anyone on an MAOI.

Watch for

  • Still made from wheat, so it contains gluten and is off limits for celiac disease and gluten sensitivity, low FODMAP or not
  • The long fermentation raises tyramine, which can trigger migraine or a dangerous spike for people taking MAOI medication
  • Only a true 16 to 24 hour ferment lowers the fructans: supermarket loaves flavored with sourdough but proofed quickly stay high FODMAP
