This is one of my theories as well. Lending to that theory is eating chicken soup which has enzymes with anti-inflammatory properties appear to also reduce the symptoms, but that also introduces many other factors.

What dietary changes can be made to reduce inflammation?

Less sugars, carbs, and highly glycemic foods such as wheat, rice, and corn will probably make the most difference. Basically avoid the sorts of things in a Little Debbie snack. It'll improve your skin a lot too!

Man, I love the Little Debbies snack cakes.

What other said plus L-Glutamine seems to be part of protecting the intestens.

> On the level of tissue, glutamine plays a role in maintaining the normal integrity of the intestinal mucosa.,[12] but randomised trials provide no evidence of any benefit of nutritional supplementation.[12]

It's cheap to buy and try if it changes anything for you.

Antiinflammatory foods are well established online, certain fruits and things (cinnamon, figs, etc).

But the ones people miss a lot: yogurt (to empower good bacteria cultures), and cannabis (yes, marijuana).

Smoked cannabis or eaten cannabis?

Vaporized, or eaten, for healthiest results.
