How the Lowly Mushroom Is Becoming a Nutritional Star
By Robert Beelman
Mushrooms are often considered only for their culinary use because they are packed with flavor-enhancers and have gourmet appeal. That is probably why they are the second most popular pizza topping, next to pepperoni.
In the past, food scientists like me often praised mushrooms as healthy because of what they don't contribute to the diet; they contain no cholesterol and gluten and are low in fat, sugars, sodium and calories. But that was selling mushrooms short. They are very healthy foods and could have medicinal properties, because they are good sources of protein, B-vitamins, fiber, immune-enhancing sugars found in the cell walls called beta-glucans, and other bioactive compounds.
Mushrooms have been used as food and sometimes as medicine for centuries. In the past, most of the medicinal use of mushrooms was in Asian cultures, while most Americans have been skeptical of this concept. However, due to changing consumer attitudes rejecting the pharmaceutical approach as the only answer to healing, that seems to be changing.
I study the nutritional value of fungi and mushrooms, and my laboratory has conducted a great deal of research on the lowly mushroom. We have discovered that mushrooms may be even better for health than previously known. They can be excellent sources of four key dietary micronutrients that are all known to be important to healthy aging. We are even looking into whether some of these could be important in preventing Parkinson's disease and Alzheimer's disease.
Four Key Nutrients
Important nutrients in mushrooms include selenium, vitamin D, glutathione and ergothioneine. All are known to function as antioxidants that can mitigate oxidative stress and all are known to decline during aging. Oxidative stress is considered the main culprit in causing the diseases of aging such as cancer, heart disease and dementia.

Ergo is produced in nature primarily by fungi, including mushrooms. Humans cannot make it, so it must be obtained from dietary sources. There was little scientific interest in ergo until 2005, when pharmacology professor Dirk Grundemann discovered that all mammals make a genetically coded transporter that rapidly pulls ergo into the red blood cells. They then distribute ergo around the body, where it accumulates in tissues that are under the most oxidative stress. That discovery led to a significant increase in scientific inquiry about possible role of ergo in human health. One study led to a leading American scientist, Dr. Solomon Snyder, recommending that ergo be considered as a new vitamin.
In 2006, a graduate student of mine, Joy Dubost, and I discovered that edible cultivated mushrooms were extremely rich sources of ergo and contained at least 10 times the level in any other food source. Through collaboration with John Ritchie and post-doctoral scientist Michael Kalaras at the Hershey Medical Center at Penn State, we showed that mushrooms are also a leading dietary source of the master antioxidant in all living organisms, glutathione. No other food even comes close to mushrooms as a source of both of these antioxidants.
I Eat Mushrooms, Ergo I am Healthy?

Our current research is centered on evaluating the potential of ergo in mushrooms to prevent or treat neurodegenerative diseases of aging, such as Parkinson's and Alzheimer's. We based this focus on several intriguing studies conducted with aging Asian populations. One study conducted in Singapore showed that as people aged the ergo content in their blood declined significantly, which correlated with increasing cognitive impairment.
The authors suggested that a dietary deficiency of ergo might predispose individuals to neurological diseases. A recent epidemiological study conducted with over 13,000 elderly people in Japan showed that those who ate more mushrooms had less incidence of dementia. The role of ergo consumed with the mushrooms was not evaluated but the Japanese are known to be avid consumers of mushrooms that contain high amounts of ergo.
More Ergo, Better Health?
One important question that has always begged an answer is how much ergo is consumed in the diet by humans. A 2016 study was conducted that attempted to estimate the average ergo consumption in five different countries. I used their data to calculate the estimated amount of ergo consumed per day by an average 150-pound person and found that it ranged from 1.1 in the U.S. to 4.6 milligrams per day in Italy.
We were then able to compare estimated ergo consumption against mortality rate data from each country caused by the common neurological diseases, including Alzheimer's, dementia, Parkinson's disease and multiple sclerosis. We found, in each case, a decline in the death rates with increasing estimated ergo consumption. Of course, one cannot assume a cause and effect relationship from such an exercise, but it does support our hypothesis that it may be possible to decrease the incidence of neurological diseases by increasing mushroom consumption.
If you don't eat mushrooms, how do you get your ergo? Apparently, ergo gets into the food chain other than by mushroom consumption via fungi in the soil. The fungi pass ergo on to plants grown in the soil and then on to animals that consume the plants. So that depends on healthy fungal populations in agricultural soils.
This led us to consider whether ergo levels in the American diet may be harmed by modern agricultural practices that might reduce fungal populations in soils. We began a collaboration with scientists at the Rodale Institute, who are leaders in the study of regenerative organic agricultural methods, to examine this. Preliminary experiments with oats have shown that farming practices that do not require tilling resulted in significantly higher ergo levels in the oats than with conventional practices, where tillage of the soil disrupts fungal populations.
In 1928 Alexander Fleming accidentally discovered penicillin produced from a fungal contaminant in a petri dish. This discovery was pivotal to the start of a revolution in medicine that saved countless lives from bacterial infections. Perhaps fungi will be key to a more subtle, but no less important, revolution through ergo produced by mushrooms. Perhaps then we can fulfill the admonition of Hippocrates to "let food be thy medicine."

On Thanksgiving Day 2019, right after Caroline Laur had finished giving thanks for her home, a neighbor at church told her that a company had submitted permit requests to build an asphalt plant in their community. The plans indicated the plant would be 250 feet from Laur's backdoor.
Grassroots Resistance<p>The plant that would threaten Laur's health and home was awaiting the approval of an air permit by the North Carolina Department of Air Quality which, if approved, would basically greenlight the project. "This made me get out and go door to door," Laur says. One by one, she alerted her neighbors to the prospect of the asphalt plant. "I got to meet some of my neighbors I never knew before," she says. "There's no secret that there has always been a pretty strong line between the White community and the Black community here." In the end, three neighbors joined her efforts—the Rev. Bryon Shoffner, Anita Foust, and Bill Compton. Together, they formed the Anderson Community Group to advocate for environmental justice in their community.</p><p>"We are all the four corners of the community," Laur says with a laugh. "You've got a sick old White lady, Rev. Shoffner is a disabled vet, you've got Anita, who is a Black woman, and you've got a White, old country farmer. We all come from different faiths, but we've all come together as one."</p><p>Suddenly thrust into activism, the group contacted the North Carolina Environmental Justice Network, a coalition that provides resources and connections with other groups. "We advocate, we organize, and we assist communities with whatever actions they are thinking of trying to protect themselves," says Naeema Muhammad, the network's co-director. Muhammad met with the activists from Anderson and recognized their need for legal advice, so she connected them with the Lawyers Committee for Civil Rights Under Law. The legal resources were key when the group determined that the data from the North Carolina Department of Environmental Quality's environmental justice report wasn't adding up.</p><p>The report—a requirement for all DEQ permit requests—stated that the Anderson community was 33% minority. That seemed far too low to the residents, so the Anderson Community Group did a census of each house within a 1-mile radius of the proposed plant—the same radius considered in the DEQ's environmental justice report.</p><p>"Rev. Shoffner went out into the community and did his own survey and found out that it was more than 70% minority," Laur says. "That was huge, because that changed the situation to a Title VI matter." Title VI is a federal civil rights law that prevents people from being discriminated against on the grounds of race, color, or national origin. Title VI cases require a more rigorous and comprehensive environmental justice report, so recognizing the Anderson community as a Title VI matter increases the strength of their request for a more in-depth report.</p><p>The massive difference in race demographics comes down to census data, Laur says. The DEQ was using race data from the 2010 census, which was only <a href="https://www.censushardtocountmaps2020.us/?latlng=35.77385,-78.73807&z=7&query=coordinates::36.44038,-79.36343&promotedfeaturetype=states&arp=arpRaceEthnicity&baselayerstate=4&rtrYear=sR2010&infotab=info-rtrselfresponse&filterQuery=false" target="_blank">completed by about 64% of the population of Caswell County</a>—the county where Anderson is located. Laur says the Anderson population response rate could be even lower because the community is considered <a href="https://www.nccensus.org/about-the-census#hard-to-count-communities" target="_blank">"hard-to-count" by the U.S. Census Bureau</a>.</p><p>"The people who don't fill it out are rural people who want to keep their land and don't want zoning and minorities," Laur says, which creates skewed race demographics. The Anderson Community Group said that when they brought up this issue with the director of North Carolina DEQ, he said he was aware of the problem.</p><p>"So that tells me that all the EJ reports in North Carolina that have been done may not even be valid, just like ours," Laur says. "We were told that we are the first [community members] who have ever doubted it and checked it out."</p>
Elevating Voices<p>Determined to have new data collected, the Anderson Community Group rallied in early 2020. After learning from the state Department of Air Quality, the department responsible for approving or rejecting the asphalt air permit, that 100 statements of concern from community members would be sufficient to trigger a public hearing, the Anderson group gathered letters of concern from their community. They submitted more than 108.</p><p>"Then we were told there wasn't enough concern to have a public hearing," Laur says. "So, we started inundating the [Department of Air Quality director with emails and phone calls from the community."</p><p>Finally, in February 2020, the DEQ declared a public comment period for the issue, effectively placing the air permit for the asphalt plant on hold until a public hearing August 3. The public hearing will be held online because of COVID-19, but Laur says most people in Anderson don't own computers, and won't be able to attend. When the community group filed a complaint regarding accessibility, the DEQ then allowed public comments to be submitted via voicemail.</p><p>"Well, we don't have a cell tower out here," Laur says. She has personally never been able to use her cellphone in her home, and even her landline phone drops calls frequently. Even being able to afford a landline is a luxury in Anderson, Laur says.</p>

One of the many unfortunate outcomes of the coronavirus pandemic has been the quick and obvious increase in single-use plastic products. After COVID-19 arrived in the United States, many grocery stores prohibited customers from using reusable bags, coffee shops banned reusable mugs, and takeout food with plastic forks and knives became the new normal.
Kamikatsu, Japan. Yuki Shimazu / CC BY-SA 2.0<p>This reveals a worldwide truth: Even products made mostly from easily recyclable materials like paper, aluminum or cardboard can't be sorted and recycled if they contain plastic components that can't be separated.</p><p>The truth is, some materials simply aren't recyclable, and <a href="https://advances.sciencemag.org/content/3/7/e1700782" target="_blank">only 9%</a> of all the plastic ever created has <em>been </em>recycled. As Kamikatsu's residents have painstakingly proven, no matter how many categories consumers sort their waste into or how diligently they scrub down their plastic food containers, most plastics <a href="https://www.greenpeace.org/usa/wp-content/uploads/2020/02/Greenpeace-Report-Circular-Claims-Fall-Flat.pdf" target="_blank">cannot be recycled</a>.</p><p>Meanwhile we keep hearing the <a href="https://thehill.com/opinion/energy-environment/504091-the-insanity-of-plastic-recycling" target="_blank">industry-driven narrative</a> that recycling can stop plastic from choking our marine life or littering our natural places. That's intentionally misleading.</p><p>Around the world, as in Kamikatsu, plastic is everywhere. With excessive amounts of plastic products and packaging stocked on store shelves, it's clear that zero-waste goals cannot be achieved by consumers alone. Plastic is not a "zero waste" material, so in order to achieve zero waste, companies must stop making so much plastic.</p>
Marine debris collected at Papahānaumokuākea Marine National Monument. NOAA<p>We can achieve that. The first steps include banning some of the worst and most polluting single-use plastics, placing a pause on the development of new plastics facilities, and protecting state and local governments' ability to enact more stringent regulations.</p><p>We must also shift the paradigm by holding producers responsible for the waste they create. By requiring new plastic products to contain recycled plastic and making producers fund the collection and recycling of plastic products, producers would be incentivized to design longer lasting products that can <em>actually</em> be reused and recycled.</p><p>These goals — outlined in numerous scientific studies and advocacy reports — have some forward motion. In the United States, a federal bill was recently introduced in both the House and the Senate, the <a href="https://www.congress.gov/bill/116th-congress/house-bill/5845" target="_blank">Break Free From Plastic Pollution Act</a>. If passed this bill — or others like it on the local, state or national levels — could help move the world beyond single-use plastics and make that needed systemic change a reality.</p><p>The bill hasn't moved forward since it was introduced this past February, but the world is still on a deadline. A recent study published in the journal <a href="https://science.sciencemag.org/content/early/2020/07/22/science.aba9475" target="_blank"><em>Science</em></a> looked at rising levels of plastic production and said "coordinated global action is urgently needed to reduce plastic consumption, increase rates of reuse, waste collection and recycling, expand safe disposal systems and accelerate innovation in the plastic value chain."</p><p>Requiring producers to stop making nonrecyclable products designed to be thrown out is the first step toward achieving that goal. Only then will Kamikatsu and other towns, cities and countries around the world finally be able to eliminate plastic pollution and reach 100% zero waste.</p><p><em>The opinions expressed above are those of the authors and do not necessarily reflect those of </em>The Revelator<em>, the Center for Biological Diversity or their employees.</em></p><p><a href="https://therevelator.org/author/oliviasullivan/" target="_blank">Olivia Sullivan</a> <em><em>is a zero waste associate with the U.S. Public Interest Research Group (U.S. PIRG) working on a campaign to move the United States beyond plastic.</em></em></p><p><em><em><span></span>Reposted with permission from <a href="https://therevelator.org/cities-zero-waste/" target="_blank">The Revelator</a>. </em></em></p>
The shelter in place orders that brought clean skies to some of the world's most polluted cities and saw greenhouse gas emissions plummet were just a temporary relief that provided an illusory benefit to the long-term consequences of the climate crisis. According to new research, the COVID-19 lockdowns will have a "neglible" impact on global warming, as Newshub in New Zealand reported.

The COVID-19 pandemic in the United States is the deepest and longest period of malaise in a dozen years. Our colleagues at the University of Vermont have concluded this by analyzing posts on Twitter. The Vermont Complex Systems Center studies 50 million tweets a day, scoring the "happiness" of people's words to monitor the national mood. That mood today is at its lowest point since 2008 when they started this project.
The Hedonometer measures happiness through analysis of key words on Twitter, which is now used by one in five Americans. This chart covers 18 months from early 2019 to July 2020, showing major dips in 2020. hedonometer.org<p>These same tweets also indicate a potential salve. Before pandemic lockdowns began, doctoral student <a href="https://scholar.google.com/citations?user=0P0ZYbIAAAAJ&hl=en" target="_blank">Aaron Schwartz</a> <a href="https://doi.org/10.1002/pan3.10045" target="_blank">compared tweets before, during, and after visits to 150 parks, playgrounds and plazas</a> in San Francisco. He found that park visits corresponded with a spike in happiness, followed by an afterglow lasting up to four hours.</p><p>Tweets from parks contained fewer negative words such as "no," "not" and "can't," and fewer first-person pronouns like "I" and "me." It seems that nature makes people more positive and less self-obsessed.</p><p>Parks keep people happy in times of global crisis, economic shutdown and public anger. Research has also shown that transmission rates for COVID-19 are <a href="https://www.sfchronicle.com/news/article/Is-risk-of-coronavirus-transmission-lower-15287602.php" target="_blank">much lower outdoors than inside</a>. As scholars who study <a href="https://scholar.google.com/citations?user=yFzb2EUAAAAJ&hl=en" target="_blank">conservation</a> and how nature <a href="https://scholar.google.com/citations?user=CCnUeN8AAAAJ&hl=en" target="_blank">contributes to human well-being</a>, we see opening up parks and creating new ones as a straightforward remedy for Americans' current blues.</p>
Park Visits Are Up During the Pandemic<p>According to the Hedonometer, sentiments expressed online started trending lower in mid-March as the impacts of the pandemic became clear. As lockdowns continued, they registered the lowest sentiment scores on record. Then in late May, effects from George Floyd's death in police custody and the following protests and police response once again could be seen on Twitter. May 31, 2020 was the saddest day of the project.</p><p>Recent surveys of park visitors around the University of Vermont have shown people <a href="https://osf.io/preprints/socarxiv/sd3h6" target="_blank">using green spaces more</a> since COVID-19 lockdowns began. Many people reported that parks were highly important to their well-being during the pandemic.</p>

Their impact on happiness is real, measurable and lasting.</p><p>Twitter records show that parks increase happiness to a level similar to the bounce at Christmas, which typically is the happiest day of the year. Schwartz has since expanded his <a href="https://arxiv.org/pdf/2006.10658.pdf" target="_blank">Twitter study</a> to the 25 largest cities in the U.S. and found this bounce everywhere.</p><p>Parks and public spaces won't cure COVID-19 or stop police brutality, but they are far more than playgrounds. There is growing evidence that parks contribute to mental and physical health in a range of communities.</p><p>In a 2015 study, for example, Stanford researchers sent people out for one of two walks: through a local park or on a busy street. Those who walked in nature showed <a href="https://doi.org/10.1016/j.landurbplan.2015.02.005" target="_blank">improved moods and better memory performance</a> compared to the urban group. And a team led by <a href="https://penniur.upenn.edu/people/eugenia-gina-south" target="_blank">Gina South</a> of the University of Pennsylvania showed in a 2018 study that greening and cleaning up blighted vacant lots in Philadelphia <a href="http://dx.doi.org/10.1001/jamanetworkopen.2018.0298" target="_blank">reduced local residents' feelings of depression, worthlessness and poor mental health</a>.</p>
Creative Strategies<p>It isn't easy to create new parks on the scale of San Francisco's Golden Gate Park or the Washington Mall, but smaller projects can expand outdoor space. Options include greening vacant lots, closing streets and investing in existing parks to make them safer, greener and shadier and support wildlife.</p><p>These initiatives don't have to be capital-intensive. In the University of Pennsylvania study, for example, renovating a vacant lot by removing trash, planting grass and trees and installing a low fence cost only about US$1,600.</p><p>Urban green space is most needed in neighborhoods that have lacked funding for parks, especially given <a href="https://www.nytimes.com/2020/04/08/nyregion/coronavirus-race-deaths.html" target="_blank">COVID-19's disproportionate impact on Black and Latinx people</a>.</p><p>Cities can also create parklike spaces by <a href="https://theconversation.com/with-fewer-cars-on-us-streets-now-is-the-time-to-reinvent-roadways-and-how-we-use-them-140408" target="_blank">closing streets to cars</a>. Many cities worldwide are currently retooling their transportation systems for the post-COVID-19 world in order to <a href="https://thecityfix.com/blog/bicycles-slower-speeds-livable-city-paris-mayor-anne-hidalgo-plans-ambitious-second-term-dario-hidalgo/" target="_blank">reallocate public space</a>, widen sidewalks and make more space for nature.</p><p>Urban designers, artists, ecologists and other citizens can play a direct role, too, creating pop-up parks and green spaces. Some advocates <a href="https://www.bloomberg.com/news/articles/2017-09-15/a-brief-history-of-park-ing-day" target="_blank">transform parking spaces into mini-parks</a> with grass, potted trees and seating for just the time on the meter, to make a larger point about turning so much public space over to cars.</p><p>Or cities can invest a little more. Minneapolis, Cincinnati and Arlington, Virginia, have won <a href="https://www.tpl.org/parkscore" target="_blank">national recognition</a> for their ambitious investments in public park systems. These areas could serve as models for neighborhoods that lack access to parks.</p>

A New Park Deal?<p>The United States has historically driven economic recovery with major infrastructure investments, like the New Deal in the 1930s and the 2009 <a href="https://www.investopedia.com/terms/a/american-recovery-and-reinvestment-act.asp" target="_blank">American Reinvestment and Recovery Act</a>. Such investments could easily include nature-positive spaces.</p><p>Parks are not panaceas, as evidenced by the widely publicized <a href="https://www.nytimes.com/2020/07/06/nyregion/amy-cooper-false-report-charge.html" target="_blank">racist confrontation between a white woman and a Black birder</a> in New York's Central Park in early July. But Hedonometer data add to a <a href="https://advances.sciencemag.org/content/5/7/eaax0903?utm_source=miragenews&utm_medium=miragenews&utm_campaign=news" target="_blank">growing body of evidence</a> that they provide <a href="https://doi.org/10.1073/pnas.1807504116" target="_blank">clear mental health benefits</a>.
