The Roots of Racism in Rhesus Monkeys
Dr. Laurie Santos is an Associate Professor of Psychology at Yale University. Her research provides an interface between evolutionary biology, developmental psychology, and cognitive neuroscience, exploring the evolutionary origins of the human mind by comparing the cognitive abilities of human and non-human primates. Her experiments focus on non-human primates (in captivity and in the field), incorporating methodologies from cognitive development, animal learning psychology, and cognitive neuroscience.
Laurie Santos: Our newest line of work is actually \r\ntrying to explore whether or not the monkeys share some of the aspects \r\nof human social cognition that we’re not very proud of. So these are \r\nthings like the fact that we are very, very prejudiced. Even though we \r\ndon’t realize we are, we have these implicit biases against out-group \r\nmembers, against individuals of different religions, different races and\r\n so on. And these biases play themselves out in really insidious ways. \r\nWe’d really like to know how these biases work, but there are lots of \r\npossibilities on the table for where they come from. Like, you know, we \r\ngrow up in a biased society, there are lots of kinds of cultural \r\ninfluences that are biases. Are these the real culprits, or is it \r\nsomething a little bit deeper? Is it something maybe older that might \r\nbe harder to override?
So we actually started studying whether\r\n the monkeys share some of our human-like prejudice against the \r\nout-group. Our first study really just asks this in a really simple way.\r\n We said, "Do monkeys spontaneously distinguish between guys that are in\r\n their in-group and guys that are in the out-group?" So the experiment \r\nwas super-simple. We did this down at our field site in Puerto Rico, \r\nwhere we study Rhesus monkeys. Monkeys free range around and we sort of \r\nshowed up with this sort of big billboard which had two covers at the \r\nend of it. When we opened the covers, there were two pictures of \r\ndifferent monkeys. One guy from their group and one guy from their \r\nout-group. And the really simple measure was, do the monkeys increase \r\ntheir vigilance, kind of get worried about it and stare at more the guy \r\nthat is in the out-group? Again, this is you know, first trial monkeys \r\nthat have ever really seen this weird billboard set up. But we found the\r\n expected result what you might expect from humans, which is that, \r\nspontaneously the monkeys actually direct their vigilance towards the \r\nguy who is in their out-group. The worrying thing seems to be very \r\nsimilar to the way that humans can devote their attention to out-group \r\nmembers.
And in our next line of studies, we wanted to see, \r\n"Well, are they just kind of looking longer at these guys, or do they \r\nactually treat them differently?" In other words, do they associate \r\nthem with bad things in their environment? And there’s a long line of \r\nstudies in people trying to look at whether people do this implicitly. \r\nThere’s a study known as the "Implicit Association Test" which basically\r\n asks you to do a couple of categorizations. You’re categorizing good \r\nand bad words, and you’re also categorizing in-group and out-group \r\nmembers, you know say, your religion versus a different religion.
And using this task, researchers have shown that it’s actually very\r\n hard to categorize your in-group with the bad words, and your out-group\r\n with the good words. You’re actually slower and you make more errors \r\nwhen these categories don’t match up. Suggesting that even though we \r\ndon’t like to think we do, we have these biases against out-group \r\nmembers that can play out in these really simple contexts.
\r\nSo we basically did the same categorization measure with our monkeys. \r\nWe gave them kind of series of different pictures that either matched in\r\n their valance. So they were all kind of good images to the monkeys, or\r\n they were all bad images to the monkeys. The idea in those cases was \r\nthe monkey should get bored, kind of good thing, good thing, good thing,\r\n or bad thing, bad thing, bad thing. Or we set up a list of pictures \r\nwhere the valances differed. And one of these cases was one of pictures \r\nof their in-group members and pictures of bad things in this case scary \r\nspiders. And what you found was that when the valances were \r\ninconsistent—so in other words, when the in-group members were paired \r\nwith these bad spiders—that actually increased the monkeys' processing \r\ntime suggesting they don’t treat those categories the same way. However,\r\n when you put out-group members with bad things, like spiders, they \r\nactually process them very quickly suggesting that, to a monkey a member\r\n of it’s out-group is basically, in some sense, equivalent emotionally \r\nor in terms of its valance to this scary predator spider creature.
Same thing when we tried to look at positive images. So, in-group \r\nmembers, the monkeys seems to process, like fruits really positive, you \r\nknow, good images that they want to approach and come near. But not so \r\nwith out-group members. So, when you give them pictures of out-group \r\nmembers paired with fruits, it actually takes them a lot of processing \r\ntime. What it seems like is that spontaneously the monkeys are setting \r\nup the same associations that we humans are, where they are treating \r\nout-group members like negative things and in-group members like \r\npositive things.
\r\nQuestion: Is it difficult to determine which monkeys are "in" and \r\nwhich monkeys are "out" of the group?
Laurie Santos:\r\n For monkeys, in-groups and out-groups are very simple. For humans, it’s\r\n not that simple, right? We can form groupings based on all kinds of \r\nreally stable social groups like our race, our gender, and so on. But \r\nwe also form groups on the fly. You know, we can be Red Sox fans or \r\nYankees fans. You know I can be the gray shirt-wearing person; you could\r\n be a different color shirt-wearing person. Humans can turn these \r\nthings on really spontaneously. For the monkeys, it depends on how \r\nthey’re born. So the monkeys in this population are born into a \r\nparticular social group. It’s based on who they’re related to, so they \r\nare born into a particular group, the females stay in that group for \r\ntheir whole lives and the males actually switch groups.
So, \r\nthe monkeys provide this really cool window because the females live in \r\nthese very stable groups that they’re going to be in for their whole \r\nlives, where the males actually switch. And so the males actually, you \r\nknow, are in one group for a certain stage of their lives and then \r\nswitch to a new group. So they kind of, in some sense, have to update \r\ntheir information about what group they’re in, who they like, and who \r\nthey don’t like and so on.
\r\nQuestion: What does the Rhesus monkeys’ behavior tell us about human\r\n groups?
\r\nLaurie Santos: Our conclusion from this recent line of work suggests\r\n that... first that monkeys actually spontaneously form associations, \r\nform categories of out-groups in the same way that humans do. So, the \r\nperhaps the exact same thing that humans do when they think about \r\nindividuals from a different race, the monkeys are doing when they are \r\nthinking about individuals from a different social group. Beyond just \r\nthe fact that they categorize them, they also seem to valance them in \r\nthe same way as humans do. Mainly that they tend to think of the \r\nin-group as a positive entity, maybe actually devote resources more to \r\nthe in-group, and they think of the out-group as a negative entity.
The thing in humans is that we know that this is true implicitly, \r\noften explicitly people won’t express these prejudices. But it suggests\r\n that whatever is going on at the implicit level might be a process \r\nthat’s evolutionarily quite old. And to us that suggests that getting \r\nover these kinds of biases might even be harder than social \r\npsychologists have thought before.
The monkey work is cool \r\nbecause, what we think it’s telling us is something about the roots of \r\nhuman sexism, human racism, human ageism, basically any form of human \r\ngroup ism—we’re seeing the undercurrents of this in the same cognitive \r\nprocessing we’re studying in the monkeys.

Why our prejudices may be deeply ingrained in our evolutionary development.
Northwell Health CEO Michael Dowling has an important favor to ask of the American people.
- Michael Dowling is president and CEO of Northwell Health, the largest health care system in New York state. In this PSA, speaking as someone whose company has seen more COVID-19 patients than any other in the country, Dowling implores Americans to wear masks—not only for their own health, but for the health of those around them.
- The CDC reports that there have been close to 7.9 million cases of coronavirus reported in the United States since January. Around 216,000 people have died from the virus so far with hundreds more added to the tally every day. Several labs around the world are working on solutions, but there is currently no vaccine for COVID-19.
- The most basic thing that everyone can do to help slow the spread is to practice social distancing, wash your hands, and to wear a mask. The CDC recommends that everyone ages two and up wear a mask that is two or more layers of material and that covers the nose, mouth, and chin. Gaiters and face shields have been shown to be less effective at blocking droplets. Homemade face coverings are acceptable, but wearers should make sure they are constructed out of the proper materials and that they are washed between uses. Wearing a mask is the most important thing you can do to save lives in your community.
New cancer-scanning technology reveals a previously unknown detail of human anatomy.
- Scientists using new scanning technology and hunting for prostate tumors get a surprise.
- Behind the nasopharynx is a set of salivary glands that no one knew about.
- Finding the glands may allow for more complication-free radiation therapies.

A <a href="https://www.cancer.gov/news-events/cancer-currents-blog/2020/prostate-cancer-psma-pet-ct-metastasis" target="_blank" rel="noopener noreferrer">study</a> published last spring suggests it may be the most accurate way to diagnose prostate cancer metastasis than any method previously available.</p><p>Prior to PSMA PET/CT, the primary way to look for metastatic prostate cancer was to image the body using x-ray-based CT scans and to perform bone scans, since bone is where prostate cancer often spreads. CT scans, however, often miss small tumors, and bone scans can generate false positives as a result of other damage or abnormalities that have nothing to do with prostate cancer.</p><p>PSMA PET/CT scans track the travels of an intravenously administered radioactive glucose tracer throughout the body. For hunting down prostate cancer, this tracer contains a molecule that binds to the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1472940/" target="_blank">PSMA</a> protein that's present in large amounts in prostate tumors. The molecule is linked to a radioisotope, <a href="https://netrf.org/2018/11/13/gallium-68-scan-for-neuroendocrine-tumors/" target="_blank" rel="noopener noreferrer">gallium-68</a> (Ga-68).</p><p>In last spring's research, PSAM PET/CT was shown to be 27 percent more accurate than previous methods at finding metastases (92 percent accuracy as opposed to 65 percent). In addition, it was found to be much less likely to produce false positives, and it was particularly good at detecting tumors far removed from the prostate.</p>
A good kind of avoidance behavior<p>"Radiation therapy can damage the salivary glands," says Vogel, "which may lead to complications. Patients may have trouble eating, swallowing, or speaking, which can be a real burden."</p><p>The researchers looked back through the cases of 723 patients who had undergone radiation treatment, interested in seeing if inadvertent radiation of the tubarial glands was associated with the complications experienced by the patients. It turned out that this <em>was</em> the case: In cases where more radiation had been delivered to this area, patients did indeed report more in the way of complications of the type one would expect when salivary glands are radiated.</p><p>Now that we know the tubarial salivary glands exist, therapists can stay out of their way. Vogel says, "For most patients, it should technically be possible to avoid delivering radiation to this newly discovered location of the salivary gland system in the same way we try to spare known glands."</p><p>He's hopeful that that things may be about to get at least a bit better for cancer patients: "Our next step is to find out how we can best spare these new glands and in which patients. If we can do this, patients may experience less side effects which will benefit their overall quality of life after treatment."</p>
A new survey found that 27 percent of millennials are saving more money due to the pandemic, but most can't stay within their budgets.
Taking control of bad luck<p>According to <a href="https://themanifest.com/accounting/budgeting-money-tips-for-millennials" target="_blank">a recent survey by The Manifest</a>, a business news website, millennials agree with Cramer. The study found that, of millennials surveyed, their largest expenses were housing (66 percent), educational expenses (9 percent), and health insurance (6 percent). In light of the COVID-19 pandemic, millennials are using the remaining 19 percent of their paychecks to budget and increase their savings.</p><p>About a third of millennials said they are saving more money in response to the pandemic and creating new budgets for themselves. In fact, of all generations surveyed, millennials felt the most comfortable creating personal budgets. They were also willing to think critically and adjust budgets to match financial changes, both signs that this highly-educated generation is willing to learn and adapt.</p><p>Millennials still have a rough road ahead, though. According to the survey, about half of millennials make less than $50,000 a year. That puts them into the upper-lower or lower-middle <a href="https://www.pewresearch.org/fact-tank/2020/07/23/are-you-in-the-american-middle-class/#:~:text=In%202018%2C%20the%20national%20middle,(incomes%20in%202018%20dollars)." target="_blank">income class</a>, depending on where in the country they live. That matches <a href="https://www.bls.gov/opub/mlr/2019/article/time-use-of-millennials-and-nonmillennials.htm#:~:text=Among%20full%2Dtime%20wage%20and,with%2031%20percent%20of%20nonmillennials." target="_blank" rel="noopener noreferrer">BLS data</a>, which shows millennials earning less than older non-millennials. <a href="https://www.bls.gov/opub/mlr/2019/beyond-bls/the-kids-are-alright-millennials-and-the-economy.htm" target="_blank" rel="noopener noreferrer">The BLS also notes</a> that while millennials have less debt than GenXers, most of that is student loan debt rather than mortgages.</p><p>And despite their budgetary plans, only 11 percent of millennials surveyed were able to stay within budget, while uncertainty still looms in the future job market.<em></em></p><p>With all this said, there are caveats to The Manifest survey. It hosted a relatively small sample size, only surveying 502 Americans. Of those, millennials made up 22 percent of respondents. They weren't even the largest cohort in the study. That was the baby boomers at 32 percent. </p><p>This makes the survey more suggestive than indicative. But the suggestion is that millennials, to borrow a phrase from writer Vicki Robin, are ready to reinterpret their relationship with finances.</p>
A push for financial freedom<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="a463513bfbe5a2b7d5bcc59f8be265a7"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/J-B-b393epk?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>While budgeting and financial savvy have always been important, the millennial generation will need to be far more critical of their relationship with the economy. What <a href="https://www.youtube.com/watch?v=T_tDthUWsVM" target="_blank" rel="noopener noreferrer">Robin calls the old roadmap</a>—the idea that "growth is good, more is better, game over"—is unlikely to support millennials as it did past generations. They'll need a new roadmap, charting both a new macro (the relationship between our economic and ecological footprints, for example) and micro (our individual relationships with money).</p><p>Because the macro is a whole other article, we'll stick with the micro here:</p><p><strong>1) Track and cut your spending</strong></p><p>The first step to financial freedom is to track your spending and cut unnecessary purchases. For Robin, these are often the things, services, and subscriptions that we buy out of habit, but we no longer consider whether they add value to our lives.</p><p>A pernicious modern example is the subscription economy. We subscribe to services for food, clothes, television, exercise, self-help, video games, bric-a-brac, computer programs, and on and on. These services quickly fade into the financial background as just another bill we pay. </p><p>But if we watch Netflix nine times out of ten, why pay for Hulu and Disney+ and HBO Max and CBS All access? Instead, every month or so, we should scrutinize our subscriptions to ask whether they still add value to our lives. If they don't, unsubscribe.</p><p><strong>2) Kill your debt</strong></p><p>Debt doesn't just take away money we could save elsewhere; it's also a self-replicating devourer of wealth. Your debt interest rates are almost certainly higher than your investment returns, especially on credit cards. Because of this, no matter your saving rituals, you're likely bleeding wealth the longer you remain in debt.</p><p>Instead, focus on removing debt from your life. Again, credit card debt especially. The good news is that most companies have hardship programs to help debtors. You can call them to see if they can lower your interest rates or provide other helpful services.</p><p>"Financial accommodations are generally readily available right now," Amy Thomann, the head of consumer credit education at TransUnion, <a href="https://www.nytimes.com/2020/08/29/at-home/manage-finances-save-money-millennials-coronavirus.html" target="_blank" rel="noopener noreferrer">told the New York Times</a><u>.</u> "Lenders, just like consumers, understand the hardships that are going on in the economy."</p><p><strong>3) Have an emergency fund</strong></p><p>Of course, you'll need some savings when the unexpected happens. Say—I don't know—a worldwide pandemic? Experts like Robin and Thomann recommend people have three to six months' worth of expenses on reserve. These should be in liquid assets so you can access them easily and quickly.</p><p>Of course, that's not always feasible, but you should save what you can. </p><p><strong>4) Find social outlets that don't cost</strong></p><p>The economic shutdown has offered one financial boon: It has revealed ways we can enjoy each other's company with overspending. We can host movies remotely with our friends. Play video games online. Enjoy physical-distance strolls through the park. And a host of other creative connections. After the pandemic, the occasional bar hop or Friday dinner out can still be a guilty pleasure. But unlike sitcom characters, we shouldn't be spending our social lives on the set of our favorite coffee shops or local watering holes.</p><p><strong>5) Reconsider your relationship with money</strong></p><p>Robin pushes her readers to be financially free. That is, to understand that there's an economy, people have a relationship with it, but it shouldn't become an obsession that runs their lives. As <a href="https://www.youtube.com/watch?v=xDaBjc4QyWU" target="_blank" rel="noopener noreferrer">she told <em>Big Think</em></a>: "It's like there are so many presumptions that drive us into wage [slavery], and it doesn't matter whether you are at the low end or the high end. If you are engaged in that sort of anxious process of 'more, more, more,' you are not free."</p><p>The millennial generation has certainly been dealt a bum hand, but it's perhaps defeatist, and more than a little premature, to label them the unluckiest generation. Perhaps after being led astray by the old roadmap, they will be the generation to reconsider their relationship with money—not as an end itself but a means to a healthier and more beneficial life. </p>
Two massive clouds of dust in orbit around the Earth have been discussed for years and finally proven to exist.
- Hungarian astronomers have proven the existence of two "pseudo-satellites" in orbit around the earth.
- These dust clouds were first discovered in the sixties, but are so difficult to spot that scientists have debated their existence since then.
- The findings may be used to decide where to put satellites in the future and will have to be considered when interplanetary space missions are undertaken.
What are they?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xODgyMDA0NC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYzNTM1ODc0Mn0.NH33LuauIo__sUBi4tvhwxDcsvhflDFD-Nhx9FjlSNk/img.jpg?width=1245&coordinates=148%2C0%2C149%2C0&height=700" id="cec96" class="rm-shortcode" data-rm-shortcode-id="acb78abe2ab46a17e419ad30906751d6" data-rm-shortcode-name="rebelmouse-image" />
Artist's impression of the Kordylewski cloud in the night sky (with its brightness greatly enhanced) at the time of the observations.
G. Horváth<p>The<a href="https://en.wikipedia.org/wiki/Kordylewski_cloud" target="_blank"> Kordylewski clouds</a> are two dust clouds first observed by Polish astronomer Kazimierz Kordylewski in 1961. They are situated at two of the <a href="https://www.space.com/30302-lagrange-points.html" target="_blank">Lagrange points</a> in Earth's orbit. These points are locations where the gravity of two objects, such as the Earth and the Moon or a planet and the Sun, equals the centripetal required to orbit the objects while staying in the same relative position. There are five of these spots between the Earth and Moon. The clouds rest at what are called points four and five, forming a triangle with the clouds and the Earth at the three corners.</p><p>The clouds are enormous, taking up the same space in the night sky as twenty lunar discs; covering an area of 45,000 miles. They are roughly 250,000 miles away, about the same distance from us as the Moon. They are entirely comprised of specks of dust which reflect the light of the sun so faintly most astronomers that looked for them were unable to see them at all. </p><p>The clouds themselves are probably ancient, but the model that the scientists created to learn about them suggests that the individual dust particles that comprise them can be blown away by solar wind and replaced by the dust from other cosmic sources like comet tails. This means that the clouds hardly move but are <a href="https://www.nationalgeographic.com/science/2018/11/news-earth-moon-dust-clouds-satellites-planets-space/" target="_blank">eternally changing</a>. </p>

J.

What the scientists observed, polarized light in patterns that extended outside the view of the telescope lens, was in line with the predictions of their mathematical model and ruled out other possible sources. </p>

J. Slíz-Balogh<p>The objects, being dust clouds, are very faint and hard to see. While Kordylewski observed them in 1961, other astronomers have looked there and given mixed reports over the following decades. This discouraged many astronomers from joining the search, as study co-author Judit Slíz-Balogh <a href="https://ras.ac.uk/news-and-press/research-highlights/earths-dust-cloud-satellites-confirmed" target="_blank">explained</a>, <em>"The Kordylewski clouds are two of the toughest objects to find, and though they are as close to Earth as the Moon are largely overlooked by researchers in astronomy. It is intriguing to confirm that our planet has dusty pseudo-satellites in orbit alongside our lunar neighbor."</em></p>

Knowing about a massive dust cloud that could damage sensitive equipment already being there could save money and lives in the future. While we only know about the clouds at Lagrange points four and five right now, the study's authors suggest there could be more at the other points.</p><p>While the discovery of a couple of dust clouds might not seem all that impressive, it is the result of a half-century of astronomical and mathematical work and reminds us that wonders are still hidden in our cosmic backyard. While you might never need to worry about these clouds again, there is nothing wrong with looking at the sky with wonder at the strange and fantastic things we can discover. </p>

Weeding through propaganda and bunk science to find credible evidence of any diet is difficult, though many experts agree that for individual and societal health, a plant-based diet is key. </p><p>Even vegetarianism has its pitfalls. For example, <a href="https://michaelpollan.com/books/cooked/" target="_blank">one-fifth of all calories</a> consumed by Americans come from nutritionally-worthless white flour. If you're eating processed bread every day, you're missing out on the benefits of a rich and varied diet. </p><p>Many of the "<a href="https://www.who.int/chp/chronic_disease_report/media/Factsheet4.pdf?ua=1" target="_blank">diseases of affluence</a>," such as cardiovascular and obesity-related ailments, originate with a poor diet (and lack of exercise). Meat has been an essential component of the human diet throughout our evolution. Today, we eat too much of it—and too much of it is produced in factory farms. Transitioning to a plant-based diet could help cut down on carbon emissions and the aforementioned diseases. </p><p>Plants are full of valuable phytochemicals and antioxidants that support a <a href="https://www.mdanderson.org/publications/focused-on-health/5-benefits-of-a-plant-based-diet.h20-1592991.html" target="_blank" rel="noopener noreferrer">strong immune system</a>. A (non-processed) plant-based diet reduces inflammation and offers plenty of fiber. It has been shown to reduce your risk of diabetes, stroke, and heart diseases. Those are all great reasons to transition. </p><h3>Begin your journey with a single step</h3><p>Going cold turkey rarely works for addicts. The same is true of diets. If you're interested in a plant-based diet, try to eat veg every other day for a few weeks. Notice how your body reacts on days you eat this way compared to other days. Gradually phase out meat products. Attempt meat-free weekdays and see if your craving for meat persists on the weekend. Try using meat as a garnish instead of the main course. </p><p>More importantly, have a replacement plan. Dropping all meat products to consume frozen dinners isn't the best course of action. Filling your cart with bags of foods you've never eaten before will overwhelm you. Prepare meals as you taper off of meat; arm yourself with a broad knowledge of healthy plants and vegetables. At some point, you might forget what you've been missing. </p>

Transitioning into a new diet requires a certain level of enjoyment. Otherwise, you're going to loathe eating, and eating should bring some level of satisfaction. </p><p>Try a one-to-one ratio to begin. On one night, cook a meal you love. Then try something completely new the next night. Follow that up with old faithful. This way, you constantly have new dishes to look forward to yet don't get stuck in thinking you have to be creative every single day. You'll likely find some winners and decide not to repeat other dishes. Regardless, you'll have a broader menu to work from. </p><h3>Avoid ingredients you can't pronounce</h3><p>The produce section of your grocery store provides almost everything you need to survive. You can likely pronounce every ingredient in this section. There's a vast difference between food and foodstuffs. Plenty of plant-based companies offer too much of the latter. Potato chips are technically vegetarian, and some use simple ingredients, yet it's easy to fill your cart with foodstuffs. The health benefits of this are not only negligible but potentially dangerous. </p><p>Qi Sun, an assistant professor of nutrition at the Harvard T.H. Chan School of Public Health, <a href="https://www.webmd.com/diet/obesity/news/20191104/are-there-health-downsides-to-vegetarian-diets" target="_blank">explains</a>. "If you eat a vegan diet, but eat a lot of french fries, refined carbs like white bread, white rice, that's not healthy." He suggests "emphasizing fruits and vegetables. Not fruit juice but whole food. And nuts."</p><h3>Utilize the wisdom of the internet—but don't get indoctrinated</h3><p>There's a lot of terrible advice—and worse, propaganda—on the internet. While you likely don't want to eat eggs every day, they're not "toxic," as one popular documentary claims. Eggs are <a href="https://www.bbcgoodfood.com/howto/guide/ingredient-focus-eggs" target="_blank">one of the best</a> low-cost, high-value foods around. </p><p>Read websites like <a href="https://www.everydayhealth.com/diet-nutrition/scientific-benefits-following-plant-based-diet/" target="_blank">Everyday Health</a>, which uses clear language, like "may improve" and "may decrease," with links to credible studies. This way you follow the going science without becoming fanatical about a particular diet or being disappointed if it turns out the research doesn't hold up. Good science evolves with evidence. And right now, the evidence points to more vegetables in our diets. </p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a> and <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank" rel="noopener noreferrer">Facebook</a>.
