Excessive inflammation may play a role in a number of leading causes of death and disability, including type 2 diabetes, obesity, and heart disease. But what are the stimuli that jumpstart the deleterious inflammatory cascade?

You typically hear about the pro-inflammatory nature of a chronic high-fat diet, but the inflammatory effect “may not be limited to chronic intake but may be evident after the consumption of a single meal.”

Within hours after eating an unhealthy meal, inflammatory markers like (IL-6), interleukin-6, can skyrocket, doubling within six hours. 

The majority of studies show an increase in IL-6 after the consumption of a high-fat meal. But the meals they tested weren’t just filled with meat, eggs, dairy, and oil, but also junky refined carbs like white flour and added sugar.

Yes, give people essentially straight butter fat and no carbs, and you can still get a spike in inflammation within hours, proving the added fat itself is pro-inflammatory. 

But give people straight sugar water without any fat, and you can get the same thing, proving the added sugar is pro-inflammatory too.

Why should we be concerned with the inflammatory responses after unhealthy meal ingestion? Because substantial research points to the notion that persistent low-grade inflammation is an underlying factor in several high-mortality chronic diseases, 

and that diet can contribute to, or attenuate, that inflammation.You’ll note in this graph that IL-6 levels jumped up to about 3 pg/mL.

You start regularly getting up to levels of about 3 pg/mL, and that’s associated with twice the risk of death.

That increased risk was found across the board, compiling eight other similar studies, likely because it’s linked with increased risk of heart disease,

the #1 killer of men and women, even about as strongly as some other major established risk factors like high cholesterol.

Now, not all high-fat foods cause inflammation. More than a dozen studies combined show that whole plant foods such as nuts do not increase inflammatory markers, 

even eating up to handfuls of nuts a day. In fact, spread half an avocado on a beef burger, and you may be able to blunt some of the inflammation caused by the meat—even lean meat.

There are reviews purporting to show a drop in inflammatory markers after eating wild game, which is about as lean a meat as you can get, but that’s only compared to store-bought meat. 

Give people some really fatty meat, and their IL-6 shoots up, as does their tumor-necrosis factor and C-reactive protein. Inflammatory, inflammatory, inflammatory within hours of it going into your mouth.

But what if you instead eat a kangaroo steak, extremely low-fat on the order of elk or moose? What you get is inflammatory, inflammatory, inflammatory, again within hours of it going into your mouth. 

Now, certainly less inflammatory than conventional meat you might get at the store, but pro-inflammatory nonetheless, increasing markers of inflammation within mere hours.
