7 Foods Experts Once Said Were Bad for Us That Turned Out to Be Healthy

By Evelyn Nieves

In the future, when we're zipping around the biosphere on our jetpacks and eating our nutritionally complete food pellets, we won't have to worry about what foods will kill us or which will make us live forever.

 

 

Until then, we're left to figure out which of the food headlines we should take to heart, and which should be taken with a grain of unrefined, mineral-rich sea salt. Low-fat or high-fat? High-protein or vegan? If you don't trust what your body tells you, remember that food science is ever evolving. Case in point: The seven foods below are ancient. But they've gone from being considered healthy (long ago) to unhealthy (within the last generation or two) to healthy again, even essential.

 

1. Coconut Oil

 

Old wisdom: Coconut oil is a saturated-fat body bomb that should be avoided.

New wisdom: Coconut oil can cure what ails you.

 

Talk about an about-face. Anyone who grew up eating such nutritious fare as SpaghettiOs, Nestle Quik and Bisquick—actually, anyone old enough to vote in the U.S.—probably doesn't remember a jar of coconut oil in the cupboard, or anywhere in the family diet.

 

Why? Coconut oil was stigmatized after flawed studies decades ago tested partially hydrogenated coconut oil for its ill effects. Now, of course, we know that the chemical process of hydrogenation is what does a body ill. That's true whether the oil consumed is coconut, corn, canola, soy or any other. 

 

It turns out that unrefined coconut oil offers terrific health benefits. Yes, it is a saturated fat. But the scientific consensus on whether saturated fats are bad for us is changing. Now researchers are stressing that saturated fats like coconut oil actually lower bad cholesterol in our bodies. Studies of people in countries that consume high amounts of coconut oil have found fewer instances of heart disease than in nations, such as the U.S., where coconut oil has not been a staple. Coconut oil is rich in lauric acid, which is known for its antiviral, antibacterial, anti-inflammatory, anti-microbial properties. Coconut oil, the new wisdom says, is good for our bodies inside and out. Studies and anecdotal evidence across the blogosphere tout coconut oil as a wondrous beauty aid, which can and should be used as a moisturizer to reduce lines and wrinkles, a moisturizer for dry hair, a soap and mouthwash. 

 

 

Old Wisdom: Coffee equals caffeine equals bad for you. 

New Wisdom: Coffee is loaded with antioxidants and other nutrients that improve your health. Plus, a little caffeine makes the world go round.

 

Why? Actually, most of the world never bought into the whole caffeine/coffee scare that made so many Americans start to swear off coffee, or heaven help us, switch to decaf. But these days, the U.S., chock full of Starbucks, has come around. Several prominent studies conducted over the last few years unearthed a bounty of benefits in the average cup of joe. As everyone knows, caffeine boosts energy. Based on controlled human trials, it has also been proven to fire up the neurons and make you sharper, with improved memory, reaction time, mood, vigilance and general cognitive function. It can also boost your metabolism, lower your risk of Type II diabetes, protect you from Alzheimer's disease and dementia, and lower the risk of Parkinson's. Whew. 

 

3) Whole Milk

 

Old wisdom: High-fat milk lead to obesity. Exposing children to lower-fat options keeps them leaner and healthier and instills the low-fat habit.

New Wisdom: Ha!

 

A study at Harvard University found that despite recommendations from the American Academy of Pediatrics that children drink skim or low-fat milk after age two, doing so did not make for leaner or healthier children. In fact, the study found the opposite. Kids who consumed skim milk were likely to be fatter than those who drank it whole. Turns out that skim drinkers were more likely to indulge in junk food, which spiked their blood sugar levels, leading to more cravings for junk. And so on and so on.

 

4) Salt

 

Old Wisdom: Salt kills. It raises blood pressures, causes hypertension and increases the risk of premature death.

New Wisdom: Salt is essential to health. Too little salt can actually lead to premature death.

 

The new wisdom is actually older than the old wisdom. Long before it became the number-one evildoer in the Department of Agriculture's hit list, worse than fats, sugar and booze, salt was considered so valuable to body and soul that it was literally used as currency. Homer called it a "divine substance." Plato described is as dear to the Gods. The Romans considered it the spice of life; a man in love was salax—in a salted state. Only fairly recently, in that oh-so-wise 20th century, did salt become the bad guy at the dinner table.

 

It turns out that high-sodium processed "food" is the real villain in our diets. Unrefined salt, such as Himalayan salt or raw sea salts, contain 60 or more valuable trace minerals. It supports thyroid function and a faster metabolism and speeds the elimination of cortisol, the stress hormone that causes weight gain. Did you know salt is also a natural antihistamine (a pinch on the tongue may stem an allergic reaction). Finally, unrefined salt is needed for good digestion. 

 

 

Old Wisdom: Chocolate gives you pimples, makes you fat and creates heartburn.

New Wisdom: Dark chocolate is loaded with antioxidants.

 

Chocoholics of the world rejoiced when the food scientists started doing an about-face on chocolate. After a few decades on the vilified list, in 2001, scientists began doing a double take, with the New York Times reporting that the science on chocolate was up in the air. Ten years later, chocolate had moved squarely into the good-for-you column. A 2011 Cambridge University study concluded that chocolate "probably" lowers stroke rates, coronary heart disease and high blood pressure. A more recent study has found that regular chocolate consumers are often thinner than non-chocolate eaters.

 

No one is advising you to grab a Snickers bar for lunch, though. Eating chemically laden, sugar-bombed milk chocolate is still a no-no…for now, anyway.

 

6) Popcorn

 

Old Wisdom: Popcorn is junk food.

New Wisdom: Popcorn is a whole grain, loaded with nutrients.

 

Like most of the foods on this list, this one has caveats. If you consider popcorn something to douse with "butter-flavored topping" and shovel in your mouth at the multiplex, then keep it on the "bad" list. A study by the Center for Science in the Public Interest has concluded that movie theater popcorn—a medium tub, mind you—has 1,200 calories and 60 grams of the worst kind of saturated fat. And that's before you add whatever it is that is supposed to taste like butter. That calorie count is the equivalent of three McDonald's Quarter Pounders.

 

Microwave popcorn, laden with chemicals, is also bad. But homemade, air-popped (let's add organic, for good measure) or made with good oil popcorn, well, that's a snack of a different color. Last year, researchers at the University of Scranton revealed that homemade popcorn has more antioxidants—known as polyphenols—than fruits and vegetables. Polyphenols have been shown to reduce the risk of heart disease and cancers.

 

If that isn't enough to make popcorn addicts rejoice, popcorn is a great source of fiber (it's a whole grain) and is low in calories. Air-popped popcorn is the healthiest of all, with only 30 calories per cup. 

 

7) Eggs

 

Old Wisdom: Eggs clog your arteries and increase your risk of heart attack, stroke, diabetes and early death.

New Wisdom: Nonsense! Eggs are very nearly the perfect food.

 

How did this one happen? A century ago, when our grandparents gathered their eggs from the backyard hens, there was no controversy. Then cholesterol became the big bugaboo, and all of a sudden, we were being lectured to limit our consumption of eggs to four a week, if any.

 

Last year, scientists decided to settle the matter once and for all. A meta-analysis of 17 studies on egg consumption and health discovered that eggs did not contribute—at all—to heart disease or stroke in healthy individuals. On the contrary, eggs raise our good (HDL) cholesterol numbers and change the bad (LDL) cholesterol from small and dense to large and benign. Eggs are also high in iron and protein and two antioxidants, lutein and zeaxanthine, which protect against age-related eye disorders like macular degeneration and cataracts.  

 

The key is to eat eggs from free-range, happy and healthy chickens, just like in the old days, and avoid eggs that come from sickly, antibiotic-soaked, factory farm hens.

As we look for advanced technology to replace our dependence on fossil fuels and to rid the oceans of plastic, one solution to the climate crisis might simply be found in rocks. New research found that dispersing rock dust over farmland could suck billions of tons of carbon dioxide from the air every year, according to the first detailed large scale analysis of the technique, as The Guardian reported.

Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Niq Steele / Getty Images

The patient in the case report (let's call him Tom) was 54 and in good health. For two days in May, he felt unwell and was too weak to get out of bed. When his family finally brought him to the hospital, doctors found that he had a fever and signs of a severe infection, or sepsis. He tested positive for SARS-CoV-2, the virus that causes COVID-19 infection. In addition to symptoms of COVID-19, he was also too weak to move his legs.

When a neurologist examined him, Tom was diagnosed with Guillain-Barre Syndrome, an autoimmune disease that causes abnormal sensation and weakness due to delays in sending signals through the nerves. Usually reversible, in severe cases it can cause prolonged paralysis involving breathing muscles, require ventilator support and sometimes leave permanent neurological deficits. Early recognition by expert neurologists is key to proper treatment.

We are neurologists specializing in intensive care and leading studies related to neurological complications from COVID-19. Given the occurrence of Guillain-Barre Syndrome in prior pandemics with other corona viruses like SARS and MERS, we are investigating a possible link between Guillain-Barre Syndrome and COVID-19 and tracking published reports to see if there is any link between Guillain-Barre Syndrome and COVID-19.

Some patients may not seek timely medical care for neurological symptoms like prolonged headache, vision loss and new muscle weakness due to fear of getting exposed to virus in the emergency setting. People need to know that medical facilities have taken full precautions to protect patients. Seeking timely medical evaluation for neurological symptoms can help treat many of these diseases.

What Is Guillain-Barre Syndrome?

Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Most commonly, the injury involves the protective sheath, or myelin, that wraps nerves and is essential to nerve function.

Without the myelin sheath, signals that go through a nerve are slowed or lost, which causes the nerve to malfunction.

To diagnose Guillain-Barre Syndrome, neurologists perform a detailed neurological exam. Due to the nerve injury, patients often may have loss of reflexes on examination. Doctors often need to perform a lumbar puncture, otherwise known as spinal tap, to sample spinal fluid and look for signs of inflammation and abnormal antibodies.

Studies have shown that giving patients an infusion of antibodies derived from donated blood or plasma exchange – a process that cleans patients' blood of harmful antibodies - can speed up recovery. A very small subset of patients may need these therapies long-term.

The majority of Guillain-Barre Syndrome patients improve within a few weeks and eventually can make a full recovery. However, some patients with Guillain-Barre Syndrome have lingering symptoms including weakness and abnormal sensations in arms and/or legs; rarely patients may be bedridden or disabled long-term.

Guillain-Barre Syndrome and Pandemics

As the COVID-19 pandemic sweeps across the globe, many neurologic specialists have been on the lookout for potentially serious nervous system complications such as Guillain-Barre Syndrome.

Though Guillain-Barre Syndrome is rare, it is well known to emerge following bacterial infections, such as Campylobacter jejuni, a common cause of food poisoning, and a multitude of viral infections including the flu virus, Zika virus and other coronaviruses.

Studies showed an increase in Guillain-Barre Syndrome cases following the 2009 H1N1 flu pandemic, suggesting a possible connection. The presumed cause for this link is that the body's own immune response to fight the infection turns on itself and attacks the peripheral nerves. This is called an "autoimmune" condition. When a pandemic affects as many people as our current COVID-19 crisis, even a rare complication can become a significant public health problem. That is especially true for one that causes neurological dysfunction where the recovery takes a long time and may be incomplete.

The first reports of Guillain-Barre Syndrome in COVID-19 pandemic originated from Italy, Spain and China, where the pandemic surged before the U.S. crisis.

Though there is clear clinical suspicion that COVID-19 can lead to Guillain-Barre Syndrome, many important questions remain. What are the chances that someone gets Guillain-Barre Syndrome during or following a COVID-19 infection? Does Guillain-Barre Syndrome happen more often in those who have been infected with COVID-19 compared to other types of infections, such as the flu?

The only way to get answers is through a prospective study where doctors perform systematic surveillance and collect data on a large group of patients. There are ongoing large research consortia hard at work to figure out answers to these questions.

Understanding the Association Between COVID-19 and Guillain-Barre Syndrome

While large research studies are underway, overall it appears that Guillain-Barre Syndrome is a rare but serious phenomenon possibly linked to COVID-19. Given that more than 10.7 million cases have been reported for COVID-19, there have been 10 reported cases of COVID-19 patients with Guillain-Barre Syndrome so far – only two reported cases in the U.S., five in Italy, two cases in Iran and one from Wuhan, China.

It is certainly possible that there are other cases that have not been reported. The Global Consortium Study of Neurological Dysfunctions in COVID-19 is actively underway to find out how often neurological problems like Guillain-Barre Syndrome is seen in hospitalized COVID-19 patients. Also, just because Guillain-Barre Syndrome occurs in a patient diagnosed with COVID-19, that does not imply that it was caused by the virus; this still may be a coincident occurrence. More research is needed to understand how the two events are related.

Due to the pandemic and infection-containment considerations, diagnostic tests, such as a nerve conduction study that used to be routine for patients with suspected Guillain-Barre Syndrome, are more difficult to do. In both U.S. cases, the initial diagnosis and treatment were all based on clinical examination by a neurological experts rather than any tests. Both patients survived but with significant residual weakness at the time these case reports came out, but that is not uncommon for Guillain-Barre Syndrome patients. The road to recovery may sometimes be long, but many patients can make a full recovery with time.

Though the reported cases of Guillain-Barre Syndrome so far all have severe symptoms, this is not uncommon in a pandemic situation where the less sick patients may stay home and not present for medical care for fear of being exposed to the virus. This, plus the limited COVID-19 testing capability across the U.S., may skew our current detection of Guillain-Barre Syndrome cases toward the sicker patients who have to go to a hospital. In general, the majority of Guillain-Barre Syndrome patients do recover, given enough time. We do not yet know whether this is true for COVID-19-related cases at this stage of the pandemic. We and colleagues around the world are working around the clock to find answers to these critical questions.

One of the initial reasons social distancing guidelines were put in place was to allow the healthcare system to adapt to a surge in patients since there was a critical shortage of beds, ventilators and personal protective equipment. In fact, masks that were designed for single-use were reused for an entire week in some hospitals.

By Jake Johnson

Unity Task Forces formed by presumptive Democratic presidential nominee Joe Biden and Sen. Bernie Sanders unveiled sweeping party platform recommendations Wednesday that—while falling short of progressive ambitions in a number of areas, from climate to healthcare—were applauded as important steps toward a bold and just policy agenda that matches the severity of the moment.

"We've moved the needle a lot, especially on environmental justice and upping Biden's ambition," said Sunrise Movement co-founder and executive director Varshini Prakash, a member of the Biden-Sanders Climate Task Force. "But there's still more work to do to push Democrats to act at the scale of the climate crisis."

The climate panel—co-chaired by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and former Secretary of State John Kerry—recommended that the Democratic Party commit to "eliminating carbon pollution from power plants by 2035," massively expanding investments in clean energy sources, and "achieving net-zero greenhouse gas emissions for all new buildings by 2030."

In a series of tweets Wednesday night, Ocasio-Cortez—the lead sponsor of the House Green New Deal resolution—noted that the Climate Task Force "shaved 15 years off Biden's previous target for 100% clean energy."

"Of course, like in any collaborative effort, there are areas of negotiation and compromise," said the New York Democrat. "But I do believe that the Climate Task Force effort meaningfully and substantively improved Biden's positions."

 

The 110 pages of policy recommendations from the six eight-person Unity Task Forces on education, the economy, criminal justice, immigration, climate change, and healthcare are aimed at shaping negotiations over the 2020 Democratic platform at the party's convention next month.

Sanders said that while the "end result isn't what I or my supporters would've written alone, the task forces have created a good policy blueprint that will move this country in a much-needed progressive direction and substantially improve the lives of working families throughout our country."

"I look forward to working with Vice President Biden to help him win this campaign," the Vermont senator added, "and to move this country forward toward economic, racial, social, and environmental justice."

Biden, for his part, applauded the task forces "for helping build a bold, transformative platform for our party and for our country."

"I am deeply grateful to Bernie Sanders for working with us to unite our party and deliver real, lasting change for generations to come," said the former vice president.

On the life-or-death matter of reforming America's dysfunctional private health insurance system—a subject on which Sanders and Biden clashed repeatedly throughout the Democratic primary process—the Unity Task Force affirmed healthcare as "a right" but did not embrace Medicare for All, the signature policy plank of the Vermont senator's presidential bid.

Instead, the panel recommended building on the Affordable Care Act by establishing a public option, investing in community health centers, and lowering prescription drug costs by allowing the federal government to negotiate prices. The task force also endorsed making all Covid-19 testing, treatments, and potential vaccines free and expanding Medicaid for the duration of the pandemic.

"It has always been a crisis that tens of millions of Americans have no or inadequate health insurance—but in a pandemic, it's potentially catastrophic for public health," the task force wrote.

Dr. Abdul El-Sayed, a former Michigan gubernatorial candidate and Sanders-appointed member of the Healthcare Task Force, said that despite major disagreements, the panel "came to recommendations that will yield one of the most progressive Democratic campaign platforms in history—though we have further yet to go."

 

Observers and advocacy groups also applauded the Unity Task Forces for recommending the creation of a postal banking system, endorsing a ban on for-profit charter schools, ending the use of private prisons, and imposing a 100-day moratorium on deportations "while conducting a full-scale study on current practices to develop recommendations for transforming enforcement policies and practices at ICE and CBP."

Marisa Franco, director of immigrant rights group Mijente, said in a statement that "going into these task force negotiations, we knew we were going to have to push Biden past his comfort zone, both to reconcile with past offenses and to carve a new path forward."

"That is exactly what we did, unapologetically," said Franco, a member of the Immigration Task Force. "For years, Mijente, along with the broader immigrant rights movement, has fought to reshape the narrative around immigration towards racial justice and to focus these very demands. We expect Biden and the Democratic Party to implement them in their entirety."

"There is no going back," Franco added. "Not an inch, not a step. We must only move forward from here."
