Inflammatory markers can double within six hours of eating a pro-inflammatory meal. Which foods are the worst, and which ones reduce inflammation? What does an anti-inflammatory diet look like?
Friday Favorites: Foods That Cause Inflammation and Those That Reduce It
Below is an approximation of this video’s audio content. To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring, watch the above video.
Which foods cause inflammation and which foods reduce it and what does it matter? That’s what we’ll be looking at in this video and next.
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.
“Intervention studies to enhance healthy ageing need appropriate outcome measures, such as blood-borne biomarkers, which are easily obtainable, cost-effective, and widely accepted.” We need blood-borne biomarkers of mortality risk. For example, having higher levels of C-reactive protein in your blood may increase your risk of dying prematurely by 42 percent. C-reactive protein is the most widely used inflammatory biomarker for predicting mortality, but those with the highest levels of (IL-6), interleukin-6, another marker of inflammation, may increase premature death risk 49 percent. What can we do to bring it down?
In my last video, I talked about foods we eat that can contribute to inflammation, like meat and sugar, versus foods like nuts that don’t. But what about anti-inflammatory foods that actually attenuate that inflammation?
Let’s see what happens when you add blueberries to a high-fat meal with a high glycemic load. White potatoes, white bread, ham, cheese, butter, and more cheese, with or without a single cup of blueberries. Add blueberries, and get a significant drop in IL-6 from that meal.
What about raspberries? Feed people eggs, butter, white potatoes, white flour biscuits, and sausage, with or without two cups of frozen raspberries blended with water into a smoothie, compared to giving people the same amount of calories and carbs in banana form. Bananas were no match for meat, eggs, dairy, and crappy carbs; that resulted in a tripling of IL-6 levels within four hours. But instead, drink those two cups of raspberries, and your body is able to hold the line. Why did raspberries work whereas bananas didn’t? Maybe it’s the antioxidants.
Well, antioxidant supplements failed miserably. There was no benefit from antioxidant vitamins and minerals like vitamins C, E, beta-carotene, or selenium. Maybe it’s those special antioxidant pigments, the anthocyanins that give berries those bright red, blue, and purple colors. And indeed, that’s what dozens of randomized controlled trials have demonstrated. Whereas a half dozen studies combined show pomegranates, a fruit packed with anthocyanin pigments, can bring down inflammation over time.
What about adding spices to meals as an approach to cool down inflammation? Supplementation with grape and turmeric extracts did not affect the inflammatory response to a milkshake. But give people actual turmeric, one teaspoon a day of the whole spice, and you get a significant drop in IL-6 levels––but not when you just give people purified curcumin supplements.
Garlic powder reduced IL-6 levels as well, starting at about a half teaspoon a day. And ginger powder (ground ginger) showed the same thing, with doses ranging from half a teaspoon to one and a half teaspoons.
Of course, another way to mediate the inflammation caused by a Sausage and Egg McMuffin is to not eat it in the first place. What about just eating a plant-based diet? To my surprise, the drop in IL-6 did not reach statistical significance. Whenever a dietary intervention doesn’t have the result you expect, you always have to ask, “What was the diet they exactly ate?” The study mostly looked at the Mediterranean diet, which certainly has more plants, but maybe the diets didn’t go far enough?
To figure that out, we can turn to Dr. Turner-McGrievy’s famous New DIETs study, where people either continued to eat their fully omnivorous diets or were randomized to eat a vegan diet, a vegetarian diet, a pesco-vegetarian diet, or a semi-vegetarian diet that, for example, limited red meat. So, whereas the vegan might eat red beans and brown rice with chopped tomatoes and roasted peppers for dinner, the ovo-lacto-vegetarian might add some cheese, the pesco-vegetarian might add shrimp, and the semi-vegetarian might add some turkey sausage.
What happened within two months to their Dietary Inflammatory Index scores? The Dietary Inflammatory Index is a measure of how inflammatory your diet is. Negative scores mean your overall diet is anti-inflammatory, and the lower the better, whereas positive scores mean your diet is on balance pro-inflammatory. And that’s exactly where they all started out. No surprise, as they were eating regular diets, and our nation is awash with inflammation-related disease.
But ask people to switch to strictly plant-based nutrition, and their diet flips to become an anti-inflammatory diet. And that was the case even if they just cut out meat, or just all meat except fish. But have them instead switch mostly to poultry, or just limit their meat intake, and their diet remains inflammatory.
Now, not all plant-foods are anti-inflammatory. If all you do is boost your intake of less healthy plant foods, like juice, white bread, white potatoes, soda, and cake, you can end up even more inflamed. But if you eat a really clean diet of whole plant foods, not only do you get significant reductions in Lp(a) (which we didn’t even think was possible with diet), as well as drops in LDL cholesterol, of course, and even the most dangerous form of LDL cholesterol.
But nearly across the board, you also get a drop in inflammatory markers. We’re talking a 30 percent drop in C-reactive protein, and a 20 percent drop in IL-6. So, maybe previous studies utilizing plant-centered diets were unsuccessful because they weren’t plant-based enough, with animal products still being substantially consumed. The total elimination of animal products and processed foods may therefore be a more prudent dietary strategy to combat inflammation.
