Food Companies Are Making Their Products Addictive, and It's Sickening (Literally)
By Melissa Kravitz
Can't stop eating that bag of chips until you're licking the salt nestled in the corners of the empty package from your fingers? You're not alone. And it's not entirely your fault that the intended final handful of chips was not, indeed, your last for that snacking session. Many common snack foods have been expertly engineered to keep us addicted, almost constantly craving more of whatever falsely satisfying manufactured treat is in front of us.
"Humans have an inherited preference for energy-rich foods — like fats and sugars — and thus natural selection has predisposed us to foods high in sugar and fat," explains Jennifer Kaplan, instructor of the course Introduction to Food Systems at the Culinary Institute of America in St. Helena, California. "Food scientists know this and create ingredients that are far higher in fat and sugar than occur in nature. The most common such sugar is high-fructose corn syrup and is therefore intrinsically addictive." In fact, foods that didn't used to be sweet, like pasta sauce, are now artificially sweetened to keep consumers craving the product, with sugar levels that can rival those found in packaged desserts.
High-fructose corn syrup (HFCS) is found in everything from ketchup and salad dressing to cereal and breads — foods that aren't necessarily perceived as sweet — and sometimes even in "healthier" alternatives, like light beer. Anheuser-Busch, the St. Louis-based brewer of Bud Light, highlighted the popular beer's lack of HFCS during a controversial Super Bowl commercial. The ad, which tried to push Bud Light as the more desirable light beer because of its lack of corn syrup (as opposed to its competitors), notably annoyed the brewery's neighboring midwestern corn farmers, who are subsidized by the U.S. government to essentially keep pumping our processed foods with corn products.
So what's so bad about HFCS, the ubiquitous ingredient so essential to the inner aisles of the American supermarket? A tablespoon of the super sweet stuff packs in roughly 53 calories, 14.4 grams of carbohydrates and 5 grams of sugar, while an entire ear of corn has about 123 calories. It's much easier to ingest extra, empty calories when they're processed down to a sugary additive, which enhances the flavor of processed foods.
As an ingredient, HFCS was shown in a 2013 study to be as addictive as drugs, like cocaine or heroin, with salt proven to have similarly addictive, opioid-like qualities. Australian neuroscientist Craig Smith has studied the effect of salt cravings in humans for years, concluding that eating excessive amounts of sodium makes people crave salt more, and those who eat less junk food can benefit from lower salt cravings and therefore fewer of the negative effects associated with too much salt consumption.
Even if a food isn't overly salty, salt may sneak into packaged food more rampantly than expected. "In most cases, salt is used as a preservative to give food extended shelf life and keep food safe," explains Nia Rennix, a clinical nutritionist who specializes in weight loss and blood sugar regulation. Salt can also be used to enhance a food's color (such as making the crust of bread a more appealing golden brown), as well as a flavor enhancer in foods you may not associate with saltiness, like ketchup or breads.
You may not be tasting the salt in your mall pretzel or packaged condiments, but salt as an ingredient is keeping you hooked. "Salt is extremely addictive, just as much as sugar. The more you consume salt, the more you crave it, and manufacturers realize this," says Rennix. "They continue to add salt to foods because they want you to continue to purchase [their products]. It doesn't matter if the salt is white, pink, sea salt or crystallized — it all has the same effect on one's body." Packaging may lead you to think that certain salts are healthier, but, truly they are all the singular thing that is bad in excess: Salt.
Beyond overeating in general, eating too much salt is proven to have negative effects on human health. "Eating too much salt is not good for your health, because the extra water that you hold on to raises your blood pressure. The more salt you eat, the higher your blood pressure," Rennix explains. "All of this can put a strain on your heart, kidneys, brain and arteries, which could lead to a stroke, heart attack or kidney disease." And yet, Americans remain casually addicted to the stuff.
While addictive drugs like cocaine and heroin are illegal, the U.S. currently has no regulations on the amounts of sugar, sweeteners and salt that can be added to foods widely available in grocery stores — a fact that underlies the looming public health crises of obesity and related illnesses. According to data from the Centers for Disease Control and Prevention, 93.3 million Americans, roughly 40 percent, are affected by obesity, a condition closely associated with heart disease, stroke, type 2 diabetes, certain types of cancer and premature death. And even armed with this knowledge, many Americans are regularly lured in by food that is designed to be hard to resist.
"Making items highly palatable is just the beginning," explains chef and registered dietitian Jessica Swift, who holds an MSc in nutritional sciences. "Pumping food full of sugar to the person with the sweet tooth is what junk food companies strive for. Having that sugar could release dopamine, the feel-good hormone in the brain, which associates that food with pleasure — causing the body to crave more."
That feel-good sensation will keep you hooked on certain foods, which will bring instant comfort when consumed. "Wanting to repeat that pleasure is natural, and this can lead to over-consumption of said food," says Swift.
Self-soothing with food is a common, easy and often cheap tactic for a quick fix, but seeking that comfort can even be less obvious, especially when you're not necessarily feeling down. For example, smelling a dish outside a restaurant or at a supermarket can evoke pleasant memories that awaken cravings. "Absolutely, smelling a warm apple pie could remind you of grandma's Sunday dinners. Gingerbread could remind you of holidays with the family. [Scent can play a part in] ... the emotional attachment to food," says Swift. Associating food with pleasure keeps humans addicted even further to the foods engineered with excessive sugar, salt and fat to keep you craving more. Think of sniffing Cinnabon at the mall, a scent that has been proven to entice customers toward consuming previously unwanted calories and sugars.
While food addiction is often used colloquially, the Yale Food Addiction Scale has been developed as a measure to determine people's level of substance dependence. Still, even if not clinically diagnosed, humans can be unhealthily hooked on junk food. So how do we stop it?
"Choose moderation for foods that you think could be highly addictive for you," Swift recommends. "Make sure you are consuming a well-balanced diet and drinking plenty of fluids." When grocery shopping for items to stock your pantry with, read nutrition labels and avoid foods with high sodium and sugar content. "Do not keep these foods within arm's reach," Swift says. "Typically, when you have to put in an effort to get an item, you are less likely to consume it." At least in this case, laziness can help your health.

Coronavirus Shines Light on Zoos as Danger Zones for Deadly Disease Transmission Between Humans and Animals
By Marilyn Kroplick
The term "zoonotic disease" wasn't a hot topic of conversation before the novel coronavirus started spreading across the globe and upending lives. Now, people are discovering how devastating viruses that transfer from animals to humans can be. But the threat can go both ways — animals can also get sick from humans. There is no better time to reconsider the repercussions of keeping animals captive at zoos, for the sake of everyone's health.

Bernice Dapaah calls bamboo "a miracle plant," because it grows so fast and absorbs carbon. But it can also work wonders for children's education and women's employment – as she's discovered.
These are the world's most bicycle-friendly cities. Statista<p>"The reason we use bamboo to manufacture bicycles is because it's found abundantly in Ghana and this is not a material we're going to import," says Dapaah, one of the World Economic Forum's Young Global Leaders.</p><p>"It's a new innovation. There were no existing bamboo bike builders in our country, so we were the first people trying to see how best we could utilize the abundant bamboo in Ghana."</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="a335b5dffdd806bd6bb4debea90c2045"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/dxsb9c4HMn0?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
Supporting Students<p>Besides encouraging Ghanaians to swap vehicles for affordable bikes, Ghana Bamboo Bikes Initiative is helping students save time on walking to school so they have more time to learn.</p><p>Each time they sell a bike, they donate a bike to a schoolchild in a rural community, who might otherwise have to walk for hours to get to school.</p><p>Dapaah knows how transformative a shorter journey to school can be to academic performance. She grew up living with her <a href="https://www.youtube.com/watch?v=sb3joGYmx9A&feature=emb_logo" target="_blank">grandpa, a forester in a rural part of the country</a>.</p><p>"We had to walk three and a half hours every day before I could go to school. He later bought me a bike, so I finished senior high and wanted to go to university."</p><p>The experience inspired her to launch Ghana Bamboo Bikes Initiative with two other students at college.</p><p>"When we started this initiative, I looked back and said, when I was young, I had to walk miles before I could get to school, and sometimes if I was late, I was punished.</p><p>"Why don't we donate bikes for students to encourage them to study and so they can have enough time to be on books."</p><p>To date, they have sold more than 3,000 road, mountain and children's bikes – and Dapaah says they plan to donate <a href="https://www.entrepreneur.com/video/350343" target="_blank">10,000 bikes to schoolchildren over five years</a>.</p>
Empowering Women<p>The enterprise is also providing local jobs. It teaches young people to build bikes, particularly women and those in rural communities, where jobs can be scarce. More than 50% of people they have trained are women.</p><p>Dapaah says they want to boost the number of people they employ to 250 over the next five years and they are looking to partner with NGOs to build a childcare facility so mothers can continue to work.</p>
Reducing Emissions<p>By promoting a cycling culture in Ghana, Dapaah says they're also committed to reducing emissions in the transport sector and contributing to the UN's Sustainable Development Goals.</p><p>"I love the idea of reusing bamboo to promote sustainable cycling. People want to go green, low-carbon, lean-energy efficient," she says.</p>

Melting and crumbling glaciers are largely responsible for rising sea levels, so learning more about how glaciers shrink is vital to those who hope to save coastal cities and preserve wildlife.
Groans, Creaks, Icebergs’ Calving Splashes<p>Oskar Glowacki already knew that melting glacial ice sounds like frying bacon. As ice bubbles burst, anyone nearby can hear crackling and popping, said Glowacki, a postdoctoral scholar at the Scripps Institution of Oceanography. Using hydrophones, he and other scientists now can make more nuanced measurements of how a changing climate sounds underwater, from the groans, creaks and splashes of a calving iceberg to the changes in whale songs as the ocean warms.</p><p>Glowacki recently used a pair of hydrophones to study the underwater world of glaciers, publishing his findings in <a href="https://www.the-cryosphere.net/14/1025/2020/" target="_blank">The Cryosphere</a>. He and co-author Grant B. Deane measured glacier retreat by <a href="https://yaleclimateconnections.org/2020/07/melting-glaciers-sound-like-frying-bacon/" target="_blank">recording the sounds of ice</a> – from small chunks to enormous slabs – falling off the glacier and splashing into the water.</p><p>During the summer of 2016, Glowacki's team placed two hydrophones near Hansbreen Glacier in Hornsund Fjord, Svalbard. For a month and a half, they recorded sounds, also using three time-lapse cameras to collect images – including the "drop height" (how far the ice fell into the water) – so they could compare photos to the recordings. The team created a formula to represent the relationship between the size of a piece of ice falling from a glacier and the sound it makes underwater, also accounting for the pieces of ice falling from varying heights. (Hear an example of the sound an iceberg makes while calving <a href="https://soundcloud.com/user-248456662/iceberg-calving-hansbreen-glacier" target="_blank">here</a>.)</p>
Unlocking Information About Antarctic Ice Shelf<p>Other researchers also are using hydrophones to learn more about crumbling glaciers. Bob Dziak, research oceanographer with the NOAA/Pacific Marine Environmental Laboratory <a href="https://www.pmel.noaa.gov/acoustics" target="_blank">acoustics research group</a>, captured a massive calving event of the Nansen Ice Shelf in Antarctica with a hydrophone. He published the results with colleagues in <a href="https://www.frontiersin.org/articles/10.3389/feart.2019.00183/full" target="_blank">Frontiers in Earth Science</a></p><p>On April 7, 2016, satellite images showed a massive calving event had occurred on the ice shelf. The paper described it as the "first large scale calving event in >30 years."</p><p>However, once Dziak and colleagues delved into the data from three hydrophones deployed 60 kilometers east of the ice shelf, they uncovered a series of "icequakes" from January to early March 2016. He and other researchers believe that much of the ice actually broke free in mid-January to February, but it remained in the same location until an April storm – which their paper described as the "largest low-pressure storm recorded in the previous seven months" – broke the ice free.</p><p>"We suspected that the icebergs broke apart but remained in place – kind of pinned in place – until a major storm with high winds passed through the area and, finally, it was that last push that pushed the icebergs out to sea," Dziak says.</p><p>He and his co-authors wrote that "fortuitous timing and proximity of the hydrophone deployment presented a rare opportunity to study cryogenic signals and ocean ambient sounds of a large-scale ice shelf calving and iceberg formation event."</p>
Listening to Songs of Humpback Whales<p><a href="https://www.mbari.org/" target="_blank">Monterey Bay Aquarium Research Institute</a> studies the ocean, including its acoustics. One of the institute's projects involves examining the soundscape of California's Monterey Bay, including sounds from animals, humans, weather, and geologic processes like earthquakes. The researchers once even recorded an under-sea landslide. They also focus on recording and analyzing the <a href="http://www.mbari.org/humpback-song/" target="_blank">songs of humpback whales</a>. Male humpback whales' songs can be over 15 minutes in length, and they can be repeated for long periods of time – even hours. Listening to these songs and analyzing them can provide unique insights into the lives of these complex animals.</p><p>"Any time we want to study marine mammals, sound gives us a window into their lives because they use sound for all of their essential life activities, really," says institute biological oceanographer John Ryan. "Communication, foraging, reproduction, navigation – depending on the species, of course."</p><p>Previously, scientists had thought singing occurred only during courtship and mating, but now they think whales may also use song while migrating and hunting. They know song has a crucial role in the whales' lives.</p><p>"There's a whole other dimension to humpback whale song," Ryan says. "It is a mode of cultural transmission in this species. They learn songs from each other. They share songs as a population, and when populations mix and mingle, they learn new ideas, they explore with their song, improvise, and it's a real essential part of their culture."</p>

A number of conservationists claim cats are a zombie apocalypse for biodiversity that need to be removed from the outdoors by "any means necessary" – coded language for shooting, trapping and poisoning. Various media outlets have portrayed cats as murderous superpredators. Australia has even declared an official "war" against cats.
Faulty Scientific Reasoning<p>In our <a href="https://doi.org/10.1111/cobi.13527" target="_blank">most recent publication</a> in the journal Conservation Biology, we examine an error of reasoning that props up the moral panic over cats.</p><p>Scientists do not simply collect data and analyze the results. They also establish a logical argument to explain what they observe. Thus, the reasoning behind a factual claim is equally important to the observations used to make that claim. And it is this reasoning about cats where claims about their threat to global biodiversity founder. In our analysis, we found it happens because many scientists take specific, local studies and overgeneralize those findings to the world at large.</p><p>Even when specific studies are good overall, projecting the combined "results" onto the world at large can cause unscientific overgeneralizations, particularly when <a href="https://doi.org/10.1016/j.tree.2015.01.003" target="_blank">ecological context is ignored</a>. It is akin to pulling a quote out of context and then assuming you understand its meaning.</p>
Ways Forward<p>So how might citizens and scientists chart a way forward to a more nuanced understanding of cat ecology and conservation?</p><p>First, those examining this issue on all sides can acknowledge that both the well-being of cats and the survival of threatened species are legitimate concerns.</p><p>Second, cats, like any other predator, affect their ecological communities. Whether that impact is good or bad is a complex value judgment, not a scientific fact.</p><p>Third, there is a need for a more rigorous approach to the study of cats. Such an approach must be mindful of the importance of ecological context and avoid the pitfalls of faulty reasoning. It also means resisting <a href="https://doi.org/10.1111/cobi.13126" target="_blank">the siren call of a silver (lethal) bullet</a>.</p>
