I notice that my allergies get worse, and a theory is that systemic low-grade inflammation and histamine response may be due to diet. I don't have a lot of other conditions, but people with autoimmune conditions (e.g. rheumatoid arthritis) might see it get better/worse with dietary changes.

When I'm eating beans+rice and a bit of protein that I cook myself, my allergies are a lot lower.

When I cheat and eat "crap" I tend to start sneezing and rubbing my eyes.

There are a lot of variables, though, and cheat foods tend to be highly processed, high in gluten, with a lot of additives and made with seed oils, and hidden sugars, and are much higher glycemic index with higher glycemic loading, amongst other things. Plus seasonal allergies are just variable day-to-day which is another confounding factor. So I don't really know what the X factor is. I get similar effects on an atkins-style high fat beef, butter and cheese kind of diet, because it also cuts out most of those things.

My theory is that the inflammation simply high-jacks your body's attention. Meaning, it has to spend more time dealing with it as opposed to handling other conditions. I don't strongly believe that chronic inflammation is the direct causal effect of many of my health symptoms, but I do strongly believe that, overall, it makes them significantly worse than they need to be.
