Spices Keep You Healthy

At some point, after three years in Thailand, I was convinced that science had ignored the health benefits of capsaicin - the part that makes hot peppers so spicy.  Surely, I thought, this heat helped to preserve foods, in a different way than salt does.  

Today this 24 year old paper popped up on Twitter that confirms my assumption.  What I didn't recognize was that garlic and onions are even better at the killing and/or inhibiting the growth of microbes.  Though I did assume the high use of garlic in hot climates had some health benefits too.  

The authors write in the overview:

"We wondered if there are any predictable patterns of spice use and, if so, what factors might underlie them. In this article, we summarize the results of our inquiries. We found that spice use is decidedly nonrandom and that spices have several beneficial effects, the most important of which may be reducing foodborne illnesses and food poisoning."

Prediction 1. Spices should exhibit antibacterial and antifungal activity.

And this chart shows that 

Prediction 2. Use of spices should be greatest in hot climates, where unrefrigerated foods spoil especially quickly.

They looked at cookbooks from 36 countries to see what spices were used, how many recipes included spices, how many spices per recipe, and which spices.  The used a climate atlas to rate the climate in each of the 36 countries. 

Prediction 3. A greater proportion of bacteria should be inhibited by recipes from hot climates than from cool climates.  

". . . the mean fraction of recipes that called for each one of the highly inhibitory spices used in those countries increased significantly (Figure 8a). However, this correlation did not hold for less inhibitory spices (Figure 8b). There was also a positive relationship between the fraction of bacterial species inhibited by each spice and the fraction of countries that used that spice, indicating widespread use of the spices that are most effective against bacteria."

There are a number of other things they looked into (ie. cost of spices, lemon/lime juice increases anti-microbial power of spices).  

So one question I have relates to the fact that our bodies rely on microbes to keep us healthy.  My awareness of this came well after 1999 (when the spice article was published) and I'm not sure how well it was known in 1999 or by the authors.  Do spices harm the gut biome?  

The article is written in clear language that should be easy for most people to understand most parts.  It also has pictures of spices as well as straightforward charts.  

Darwinian Gastronomy: Why We Use Spices: Spices taste good because they are good for us 

Paul W. Sherman,   Jennifer Billing  Author Notes  BioScience, Volume 49, Issue 6, June 1999, Pages 453–463, https://doi.org/10.2307/1313553   Published: 01 June 1999

They use' microbe' in some places and 'bacteria' in other places.  Since I wasn't completely sure about what each term meant, I found this American Society for Microbiology page "What Counts As A Microbe?"

Interconnections - Oil and Democracy, Microbes and Human Behavior

The world is complicated and humans are constantly tracking down the linkages between different factors.  The first seems much easier to understand, though confirmation bias plays a big role in how easy it is for someone to understand the link between oil and democracy.


1.  Oil's Impact on Democracy

From Philosophasters

OIL IS THE DEVIL'S EXCREMENT
SEPTEMBER 28, 2017 BY DAVID JACQUES IN ARTICLES
Juan Pablo Pérez Alfonzo was a prominent Venezuelan politician who served two terms in office with the Centrist Betancourt Administration (1947-48 & 1959-64). As Minister for Energy he was drawn into conflict with the U.S. under Eisenhower who had negatively affected quotas on Venezuelan oil by favouring new trade agreements with Canada and Mexico. Alfonzo’s response was to form an alliance with oil producing Arab nations in an attempt to regulate the global oil market. His ideas came to fruition with the establishment of 'The Organisation of Oil Producing Countries' - OPEC.
However, protection within the market and the promise of unfettered wealth arising from Venezuela’s immense oil reserves were undone by what economists came to term the 'natural resource curse'; the sudden influx of money would cause the national currency to dramatically appreciate, wages are driven up, prices inflate, manufacturing, imports and exports all slump. Though this was yet to occur for Venezuela during the early OPEC years, Alfonzo saw it all coming. In a prophetic 1975 speech he uttered the infamous lines: "ten years from now, twenty years from now, you will see; oil will bring us ruin. Oil is the Devil's excrement".

  MSNBC host Rachel Maddow talks about the oil and gas industry’s impact on democracy around the world, tying in Russia’s interference in the 2016 presidential election, the impeachment inquiry of Donald Trump, and more. On October 6, 2019, Rachel Maddow came to the Sydney Goldstein Theater to read from her new book “Blowout: Corrupted Democracy, Rogue State Russia, and the Richest, Most Destructive Industry on Earth”. Maddow spoke to Dan Pfeiffer, a former advisor to President Barack Obama who now co-hosts “Pod Save America”.

I highly recommend Confessions of an Economic Hitman.  It tells the story of how international corporations funnel trillions of public dollars into their own coffers.  It's short and easy to read.  The link tells more about why I recommend it.


2.  Gut Microbes' Impact on Behavior.  

From Science Magazine

Animal sociability through microbes
Accumulating evidence suggests that the microbiota living in and on animals has important functions in the social architecture of those animals. Sherwin et al. review how the microbiota might facilitate neurodevelopment, help program social behaviors, and facilitate communication in various animal species, including humans. Understanding the complex relationship between microbiota and animal sociability may also identify avenues for treating social disorders in humans.
Science, this issue p. eaar2016

These studies are in mice and from the abstract All I could tell was that it affected 'sociability.'
I learned about 10 years ago how my body's functioning was dependent on microbes living inside me.  Finding out the there are 10 times more microbial cells in my body than human cells caused a major shift in how I understand the world and what it means to be human.  I'd note that because the microbial cells are very small, they only make up about 1-3 percent of human body mass.

3.  Census Methodology Impacts on  Gerrymandering

It's no secret that how and who the Census Bureau counts in decennial census counts impacts elections. People who pay attention to the news are aware of the Trump administration's attempt to add a question about citizenship on the 2020 census which would have (and even though it failed, still might have) the effect of causing non-citizens to hide from census takers.

But this article is about how the census bureau counts prisoners - in the community where the prison is located.  Here's the beginning of a primer from the Prison Gerrymandering Project:

"The way the Census Bureau counts people in prison creates significant problems for democracy and for our nation’s future. It leads to a dramatic distortion of representation at local and state levels, and creates an inaccurate picture of community populations for research and planning purposes.
The Bureau counts incarcerated people as residents of the towns where they are confined, though they are barred from voting in 48 states and return to their homes after being released. The practice also defies most state constitutions and statutes, which explicitly state that incarceration does not change a residence."

4.  Blogger Best Wishes and Better New Year

I couldn't find any studies on how blogging good wishes for the new year actually impacts people's
New Year.  I did find this opinion heavy and fact light article on the effects of kindness.  One link is to a Dr. Emoto (really!) who studied how kindness helps water crystals form better and since human bodies are 60% water (plus 3% microbes) being kind helps the water in your body.

There's something off balance in the number 2019.  2020 is much more in tune with human aesthetics.  So I'm wishing you all a great 2020.  Find the good in every day.

HA! Brave New World: It Looks Like Being Too Clean Can Hurt You

Despite my flip title, this piece from Nature [this comes from the Nature News section and is not from the actual scientific report in Nature by Alejandro Reyes, Matthew Haynes Nicole Hanson, Florent E. Angly, Andrew C. Heath, Forest Rohwer, & Jeffrey I. Gordon] says there's a world of bacteria and viruses living inside us that do work for us we couldn't live without. 

These findings, preliminary as they might be, demonstrate that despite all we do know about how the human body functions, there is still so very much more to know. 

More than 10 trillion bacteria normally inhabit the gastrointestinal tract, where they synthesize essential amino acids and vitamins, produce anti-inflammatory factors and help break down starches, sugars and proteins that people could not otherwise digest. Within and among these bacteria live bacterial viruses, or bacteriophages, which affect bacterial numbers and behaviour as they either prey on bacteria or co-exist with them, shuttling genes from one bacterium to another.

This microscopic dynamic ecosystem affects our lives in ways we still do not fully understand. Indeed, the rise in the incidence of food allergies in Western societies has led to hypotheses that extreme hygiene disrupts the ability of microbes to colonize human guts, resulting in a lack of tolerance to usually harmless foods. 

. . ."This human ecosystem is quite important because it determines what we can do and what we can eat," says [Edward] DeLong [at the Massachusetts Institute of Technology in Cambridge.] "That's why we should care about this." 

A brief NY Times editorial alerted me to this article.   Though the original Nature News article isn't that long or technical itself.  The actual scientific article requires payment if you aren't a subscriber to get more than the abstract.
