An anti-inflammatory diet now can protect your brain from dementia later

"Currently, inflammation is considered a major factor in the development of depression, dementia, and other brain disorders," says Dr Drew Ramsey. 


Every year you can expect a slew of new “guaranteed diet” books for weight loss, brain health, aging, spiritual well-being, and general lifestyle. There’s the vegan one, the raw meat one, the low-fat one, the high-fat one, the juice-from-fruits-picked-during-a-full-moon one, the blood type one, and the one based on your latest tarot card reading. It becomes quite confusing. Authors confuse a little information with knowledge, then try to translate that into sales.

There are too many factors to factor in to a proper diet. Serious nutritionists recognize that good health requires a nuanced understanding of individual genetics, environment, and gut microbiome. Then there’s the speed you consume your food, the types of sugar you eat—in juice or whole fruit, in which the fiber plays a critical role—then the types of fat you digest, and stress levels.

Let’s pause on that last one for a moment, as stress is rampant. An overtaxed body is an inflamed body. A recent study investigating the role of inflammation in regards to brain health and dementia is worth considering. It’s not the only factor in a good diet, but it is a crucial one. 

A team at Columbia University Medical Center, led by neuropsychologist and epidemiologist Yian Gu, studied the cognitive performance of 330 elderly adults to see if the Mediterranean diet—one of the longer-lasting and most-studied diets in the world—could lower their risk of diseases of dementia, including Alzheimer’s. All adults involved did not suffer from dementia during the course of the study. 

Gu points out numerous studies have shown that this diet, which is fish- and poultry-heavy with an emphasis on whole grains, fruits, olive oil, vegetables, and moderate alcohol intake, offers protection against the development of Alzheimer’s. Gu wanted to know if this is due to a decrease in inflammatory biomarkers in the subject’s brain. 

The result was yes, decreased inflammatory markers were prevalent in those who ate this diet. They also had better visuospatial cognition, thanks to nutrients such as vitamins B1, B2, B5, B6, D, and E, as well as higher intake of omega 3-fatty acids, calcium, and folate. Gu notes: 

This study suggests that certain nutrients may contribute to the previously observed health benefits of some foods, and anti-inflammation might be one of the mechanisms. We hope to confirm these results in larger studies and with a wider range of inflammatory markers.

To understand why lower inflammation helps overall health and aging I emailed Drew Ramsey, also at Columbia University. The psychiatrist, Big Think expert, and author of numerous books, including Eat Complete, told me: 

Inflammation is how our body deals with stress and injury. Today, most people eat a diet and have a lifestyle that promotes incredible stress via excess sugars, eating the wrong fats, and losing the sense of joy that food should give us. Currently, inflammation is considered a major factor in the development of depression, dementia, and other brain disorders. People should worry about inflammation because it is contributing to the degradation of their health.

This is especially important as we age. As Gu and team write in the study, Alzheimer’s is the leading cause of dementia worldwide, and is the most common neurodegenerative disorder. While medical interventions help us live longer that does not always translate to healthier. We can overcome cancer and heart surgery and survive longer with AIDS and type 2 diabetes, but quality of life is greatly compromised when suffering from dementia. The strain on family and friends can be overwhelming. 

Which is why it’s important to start interventions earlier in life. Most of what is sold in packages is not food, but a combination of food-like substances preserved by unpronounceable chemistry. Sugars and unhealthy fats hide, disguised by numerous names, slowing transforming our microbiome in ways that degrade health. And it’s not only visceral fat, body mass index, and heart disease we need to worry about. Without healthy cognition the very concept of “I” disintegrates. The so-called golden years are effectively meaningless if you can’t remember them.

While studies like Gu’s remind us of the bigger picture, Ramsey suggests taking it meal by meal. When I ask him how people can implement changes in their diets now, he expresses skepticism about considering the long game. Change starts at the dinner table tonight, he says. 

People don't get motivated by “long term benefits” or “risk reduction.” We have the most success in our clinic when we encourage patients to make better food choices at their next meal. We find that there are very rapid effects when people switch from modern Western food to nutrient dense whole foods (which are also brain food). Sure, eating more avocados can decrease dementia risk, but encouraging patients to eat more avocado toast and guacamole is more compelling when it comes to behavioral change.

Gu knows that one study does not change a discourse. But the combination of better understanding the microbiome and the effects of decreasing inflammation is too prevalent to deny. The Mediterranean diet offers a simple lesson applicable globally, to eat seasonal fresh foods and enjoy moderate amounts of alcohol. Such an approach worked for our species for millions of years until the advent of refrigeration and industrial processing. And we know it works now. We just have to implement it, be it through the recognition of cognitively strong aging or, as Ramsey suggests, hitting the produce aisle for dinner tonight.

  • Push Past Negative Self-Talk: Give Yourself the Proper Fuel to Attack the World, with David Goggins, Former NAVY SealIf you've ever spent 5 minutes trying to meditate, you know something most people don't realize: that our minds are filled, much of the time, with negative nonsense. Messaging from TV, from the news, from advertising, and from difficult daily interactions pulls us mentally in every direction, insisting that we focus on or worry about this or that. To start from a place of strength and stability, you need to quiet your mind and gain control. For former NAVY Seal David Goggins, this begins with recognizing all the negative self-messaging and committing to quieting the mind. It continues with replacing the negative thoughts with positive ones.

Maps show how CNN lost America to Fox News

Is this proof of a dramatic shift?

Dramatic and misleading

The situation today: CNN pushed back to the edges of the country.

Over the course of no more than a decade, America has radically switched favorites when it comes to cable news networks. As this sequence of maps showing TMAs (Television Market Areas) suggests, CNN is out, Fox News is in.

The maps are certainly dramatic, but also a bit misleading. They nevertheless provide some insight into the state of journalism and the public's attitudes toward the press in the US.

Let's zoom in:

  • It's 2008, on the eve of the Obama Era. CNN (blue) dominates the cable news landscape across America. Fox News (red) is an upstart (°1996) with a few regional bastions in the South.
  • By 2010, Fox News has broken out of its southern heartland, colonizing markets in the Midwest and the Northwest — and even northern Maine and southern Alaska.
  • Two years later, Fox News has lost those two outliers, but has filled up in the middle: it now boasts two large, contiguous blocks in the southeast and northwest, almost touching.
  • In 2014, Fox News seems past its prime. The northwestern block has shrunk, the southeastern one has fragmented.
  • Energised by Trump's 2016 presidential campaign, Fox News is back with a vengeance. Not only have Maine and Alaska gone from entirely blue to entirely red, so has most of the rest of the U.S. Fox News has plugged the Nebraska Gap: it's no longer possible to walk from coast to coast across CNN territory.
  • By 2018, the fortunes from a decade earlier have almost reversed. Fox News rules the roost. CNN clings on to the Pacific Coast, New Mexico, Minnesota and parts of the Northeast — plus a smattering of metropolitan areas in the South and Midwest.

"Frightening map"

Image source: Reddit / SICResearch

This sequence of maps, showing America turning from blue to red, elicited strong reactions on the Reddit forum where it was published last week. For some, the takeover by Fox News illustrates the demise of all that's good and fair about news journalism. Among the comments?

  • "The end is near."
  • "The idiocracy grows."
  • "(It's) like a spreading disease."
  • "One of the more frightening maps I've seen."
For others, the maps are less about the rise of Fox News, and more about CNN's self-inflicted downward spiral:
  • "LOL that's what happens when you're fake news!"
  • "CNN went down the toilet on quality."
  • "A Minecraft YouTuber could beat CNN's numbers."
  • "CNN has become more like a high-school production of a news show."

Not a few find fault with both channels, even if not always to the same degree:

  • "That anybody considers either of those networks good news sources is troubling."
  • "Both leave you understanding less rather than more."
  • "This is what happens when you spout bullsh-- for two years straight. People find an alternative — even if it's just different bullsh--."
  • "CNN is sh-- but it's nowhere close to the outright bullsh-- and baseless propaganda Fox News spews."

"Old people learning to Google"

CNN vs. Fox News search terms (200!-2018)

But what do the maps actually show? Created by SICResearch, they do show a huge evolution, but not of both cable news networks' audience size (i.e. Nielsen ratings). The dramatic shift is one in Google search trends. In other words, it shows how often people type in "CNN" or "Fox News" when surfing the web. And that does not necessarily reflect the relative popularity of both networks. As some commenters suggest:

  • "I can't remember the last time that I've searched for a news channel on Google. Is it really that difficult for people to type 'cnn.com'?"
  • "More than anything else, these maps show smart phone proliferation (among older people) more than anything else."
  • "This is a map of how old people and rural areas have learned to use Google in the last decade."
  • "This is basically a map of people who don't understand how the internet works, and it's no surprise that it leans conservative."

A visual image as strong as this map sequence looks designed to elicit a vehement response — and its lack of context offers viewers little new information to challenge their preconceptions. Like the news itself, cartography pretends to be objective, but always has an agenda of its own, even if just by the selection of its topics.

The trick is not to despair of maps (or news) but to get a good sense of the parameters that are in play. And, as is often the case (with both maps and news), what's left out is at least as significant as what's actually shown.

One important point: while Fox News is the sole major purveyor of news and opinion with a conservative/right-wing slant, CNN has more competition in the center/left part of the spectrum, notably from MSNBC.

Another: the average age of cable news viewers — whether they watch CNN or Fox News — is in the mid-60s. As a result of a shift in generational habits, TV viewing is down across the board. Younger people are more comfortable with a "cafeteria" approach to their news menu, selecting alternative and online sources for their information.

It should also be noted, however, that Fox News, according to Harvard's Nieman Lab, dominates Facebook when it comes to engagement among news outlets.

For the record, here are the Nielsen ratings for average daily viewer total for the three main cable news networks, for 2018 (compared to 2017):

  • Fox News: 1,425,000 (-5%)
  • MSNBC: 994,000 (+12%)
  • CNN: 706,000 (-9%)

And according to this recent overview, the top 50 of the most popular websites in the U.S. includes cnn.com in 28th place, and foxnews.com in... 27th place.

The top 5, in descending order, consists of google.com, youtube.com, facebook.com, amazon.com and yahoo.com — the latter being the highest-placed website in the News and Media category.
