What to know about pesto
Pesto is a composite sauce, so its triggers stack from several ingredients at once rather than coming from one. The parmesan makes it high in free glutamate and dairy protein, the garlic makes it high in fructans, and the basil adds a moderate salicylate load. That is why people who eat plain pasta without trouble still react to pesto: a single spoonful hits an MSG-reactive or FODMAP-sensitive person harder than any one of those foods would on its own.
Watch for
- High in free glutamates from the aged parmesan, the same naturally occurring umami compound behind MSG-style reactions such as headache, flushing and sinus congestion
- High in dairy protein from the cheese, so it is off-limits if you react to casein or whey, and it is not vegan
- High in fructans from the garlic, a common FODMAP trigger for bloating and gas even in small amounts
- Moderate salicylates from the basil, worth noting if you are salicylate-sensitive and eating it alongside other salicylate-rich foods
