Clustered regularly interspaced short palindromic repeats / Cas9, better known as just CRISPR, is a form of genetic modification that utilizes the immune system of bacteria to selectively remove or replace individual genes. As you can imagine, it is a very complex concept — I recommend this great full explainer –– but it has vast implications for the future of human health and prosperity, Continue reading
According to the most recent Bloomberg Health-Care Efficiency Index, Hong Kong has the most efficient healthcare system in the world, a position it and close runner up Singapore have held since 2009. During the same span of time, Spain and South Korea climbed up to third and fourth place respectively, with Japan dropping two places but remaining at a very respectable fifth.
Here are the full results of all fifty-five countries measured. Continue reading
There has been a lot of hubbub over the last few years about most health supplements being useless, or at the very least irrelevant if one eats and lives healthy. If you want a quick and easy way to sort through all the different claims and misconceptions about purportedly health foods, herbs, and supplements, check out the “Snake Oil Superfoods” infographic over at Information is Beautiful, a website specializing in summarizing data of all kinds through gorgeous visuals.
The efficacy of certain foods for certain conditions ranges from no evidence to strong evidence, with vast majority spanning the spectrum between slight evidence to inconclusive. The brighter the bubble, the better the evidence, with blue signifying items that are worth watching due to ongoing or game changing research. Depending on which category you choose, the size of the bubble reflects the superfoods popularity among either scientists or the general public. Clicking on each bubble will yield additional information and a link to the data, though you can find all the data utilized in the chart in this nifty spreadsheet here.
Of course, it is always better to consult as many varied sources as possible, but this is definitely a comprehensive — and more stimulating — place to start.
As many fellow health buffs will no doubt attest to, it is often very difficult to get a consistent idea of what is healthy and what isn’t. Not only do laymen often disagree vehemently with one another — everyone has their own anecdote or folk remedy to swear by, science be damned — but it seems that not a month goes by without some study finding contradictory evidence about the healthiness of a particular food or beverage, often turning back years or even decades of nutrition science (e.g., the recent revelation that fat may not be so bad after all, that eggs and coffee are good for you, and that salt and sugar are far worse than previously believed).
The New York Times drives home this point with an article about a study that polled both nutritionists and a sample of the American public to compare their thoughts regarding some common nutrition battlegrounds. Unsurprisingly, the results showed a big gap between experts and everyone else, as well as revealing divisive views within each community, too. Continue reading
The vast majority of public schools in the U.S. start earlier than 8:30 a.m. Like most American students, I took this as a given, albeit begrudgingly — we all struggled to get up and get focused for school, and it only got harder with each passing year. Naturally, many people chalk this up to the laziness and entitlement of adolescence. But mounting scientific research is finding that getting up really early, and being thrown into a cognitively-intensive bloc schedule, is bad for both the health and education of youth. Various leading public health authorities are urging an end to this practice. Continue reading
Back in February, the United Arab Emirates announced the creation of a “minister of state for happiness” that would “align and drive government policy to create social good and satisfaction”, whatever that means. (The same statement announced the creation of minister for tolerance, perhaps in response to the country’s rapidly growing multicultural population.)
Needless to say, the idea of a “happiness minister” was met with a lot of confusion and amusement, both from within the country and beyond. What does it means to promote happiness on a policy level? What would this entail? And should governments even take it upon themselves to worry about this?
As The Washington Post points out, the U.A.E. is only the latest of several countries to go this route. Both Ecuador and Venezuela announced similar initiatives in 2013 — a state secretary of “good living / well-being” and a “vice ministry of supreme social happiness”, respectively — and the small Himalayan nation of Bhutan pioneering the concept back in 1972 with its “gross national happiness” (GNH) index.
In theory, these ministries work to try to improve the levels of happiness in the countries through a variety of policies. David Smilde, a senior fellow at the Washington Office on Latin America, says that despite its grandiose name, Venezuela’s ministry actually has a “pretty reasonable mandate” – measuring the effectiveness of the government’s various social welfare programs. In Ecuador, Ehlers has implemented or plans to implement a variety of policies that included both labeling foods based on their health values and meditation classes for schoolchildren, the Miami Herald reported last year.
Bhutan’s GNH measure is especially interesting, as it was devised to shift public policy focus away from economic concerns — as signified by the near-universal interest in gross domestic product (GDP) and towards promoting several components of happiness, such as mental and physical health, leisure time, and standard of living.
While there is no minister directly responsible for happiness in the tiny Himalayan nation, the Gross National Happiness Commission is tasked with surveying the levels of happiness in the nation. The information they gather is then used by the government to make decisions.
Butan’s big idea has since proven popular around the world and now a variety of countries all around the world – including Thailand and the United Kingdom – have begun measuring happiness with an aim to using it to devise policy. Dubai actually announced plans for its own Happiness Index in 2014, with Hussain Lootah, director general of the municipality, telling the National newspaper that it would be designed to “create an excellent city that provides the essence of success and comfort of sustainable living.”
Interestingly, despite leading the way in prioritizing social well being as government policy, Bhutan’s performance has been mixed at best: according to the most recent U.N. World Happiness Report, which was inspired by the GNH idea, the country ranks only 79th out of 158, not terrible but not all that great. Bhutan has also dealt with faced issues such as pervasive poverty and discrimination against non-Buddhist minorities.
Believe it or not, the same U.N. report ranked Venezuela a respectable 44th in 2016, a significant drop since 19th in 2012, when the Orwellian-sounding “vice ministry of supreme social happiness” was created. Given the country’s plethora of social, economic, and political problems — ranging from food shortages to high crime — this decline is unsurprising, though still not as damaging as one would think.
For their part, Bhutan ranked 84th, the U.A.E. 28th, and Ecuador 51st. (Wikipedia has a great breakdown of the report’s results and methodology here.) As The Post points out, the top ten countries — all of which were northern European states and small Anglophone nations — had another thing in common besides being wealthy liberal democracies:
None of the top 10 countries rated “happiest” in the U.N. report have a government ministry devoted to happiness – although given the rarity of such ministries, it’d be very surprising if they did. There’s certainly little doubt that government policies can influence levels of happiness, but whether an entire ministry is needed is not so certain. Generally, when it comes to improving levels of happiness, “what matters is how things are done across government as a whole,” says John Helliwell, a co-editor of the World Happiness Report and a senior fellow at the Canadian Institute for Advanced Research. And Carol Graham, a fellow at the Brookings Institution who has studied attempts to measure well-being, says that the creation of ministries for happiness can be a “diversion” and may even “border on the government telling people how to be happy or that they should be happy.”
And while most of the top nations were indeed highly developed, broadly prosperous states, there was a smattering or poorer or middle-income countries, such as Costa Rica (14th place), Puerto Rico (15th), Mexico (21st), Chile (24th), and Panama (25th). It goes to show that, as with individuals, there is no magic bullet when it comes to well-being and life satisfaction.
Granted, it seems to be the general rule that financial wealth, stability, and freedom — both on an individual and societal level — generally correlates with happiness. But values, community life, leisure time, and culture count for a lot, too; people or places that are lacking in some factors, but excel in others, might still end up happier on the whole.
In my view, the best thing governments can do is create the proper conditions within which happiness can thrive — effective rule of law that safeguards personal safety and stability, less intrusion into civil liberties, more public spaces for leisure and community engagement, and so on. In other words, cultivate a physical and social environment that maximizes the individual’s ability to improve their own well being. More proactive measures, such as making healthcare and education more accessible, would certainly help, too, but this could be politically unpalatable in places wary of government intrusion, like the U.S. (which, by the way, ranked a good 13th place in the U.N. happiness report.)

According to the latest Bloomberg Best (and Worst), which ranks countries in all sorts of metrics and areas, the following the healthiest (and least healthiest) nations in the world.
This health index takes into account several factors, including rates of mortality, smoking, immunization, healthcare access, satisfaction with the medical system, and life expectancy, among others. A country’s score reflects both the political factors at work — public health policies, the healthcare system, insurance regulations, etc. — as well as sociocultural influences, such as diet, lifestyle, and attitudes towards risky activities like smoking or heavy drinking.
Thus, the countries that performed the best tended to share similar characteristics: first and foremost, social, political, and economic stability (e.g., no war, mass unemployment, famine conditions, etc.); an efficient, cost-effective, and well managed universal healthcare system; good public infrastructure that promotes daily activity (parks, bicycle paths, walkable city plans, etc.); and a health-conscious culture values things like small food portions, outdoor recreation, or free time from work.
As per Jared Diamond’s work, geography and environment might play some role as well; most of the top performers were located in areas with generally stable and temperate climates, and thus far fewer diseases, erratic weather patterns, natural disasters, infectious diseases, and other detriments to individual and public health. (Singapore, which is located in a tropical region, is somewhat of an exception, but as an extremely well governed city-state, it has had an easier time minimizing or addressing the challenges poised by its climate.)
Among the three scientists awarded the 2015 Nobel Prize in Physiology or Medicine for work against parasites was Tu Youyou, an octogenarian pharmacologist whose work led to the development of the most effective treatment against malaria. But despite her invaluable role in saving millions of lives from this public health scourge, her contributions remained largely unknown, even in her own homeland.
Vox.com recounts the amazing story that led up to her breakthrough discovery.
In 1967, Chairman Mao Zedong set up a secret mission (“Project 523”) to find a cure for malaria. Hundreds of communist soldiers, fighting in the mosquito-infested jungles of Vietnam, were falling ill from malaria, and the disease was also killing thousands in southern China.
After Chinese scientists were initially unable to use synthetic chemicals to treat the mosquito-borne disease, Chairman Mao’s government turned to traditional medicine. Tu, a researcher at the Academy of Traditional Chinese Medicine in Beijing, had studied both Chinese and Western medicine, according to a New Scientist profile, and was hand-plucked to search for an herbal cure.
By the time I started my search [in 1969] over 240,000 compounds had been screened in the US and China without any positive results,” she told the magazine. But, she added: “The work was the top priority, so I was certainly willing to sacrifice my personal life.”
Tu’s dedication included first testing the promising treatment on herself, to ensure that it was safe. Once it was proven to have no side effects, she organized clinical trials for people with malaria, all of whom were incredibly cured of the disease within no more than a day. Continue reading
It is no surprise that wealthier countries, like wealthier people, tend to live longer. But how strong is this correlation? In a video released by The Gapminder Foundation, Swedish academic and professor Hans Rosling uses detailed but digestible visual data to explore the link between a nation’s wealth –namely its gross domestic product, or GDP — and the average longevity of its people.
To check out the two minute video, click here. (Sorry, I cannot embed it.)
Ultimately, the findings do indeed confirm that rich societies live longer. But what the data also show is that those countries in the middle range of GDP — e.g. the developing world — display a broad range in life expectancy, from low to surprisingly high. This illustrates the discrepancy in how states invest their growing wealth, and whether the fruits of their development are going to their people.

As if the Millennial generation didn’t have enough going against — from poorer job prospects to more expensive education — a recent study reported in The Atlantic has found that young people in the 21st century are less likely to lose or maintain weight than previous generations — even when they eat and exercise the same.
The authors examined the dietary data of 36,400 Americans between 1971 and 2008 and the physical activity data of 14,419 people between 1988 and 2006. They grouped the data sets together by the amount of food and activity, age, and BMI.
They found a very surprising correlation: A given person, in 2006, eating the same amount of calories, taking in the same quantities of macronutrients like protein and fat, and exercising the same amount as a person of the same age did in 1988 would have a BMI that was about 2.3 points higher. In other words, people today are about 10 percent heavier than people were in the 1980s, even if they follow the exact same diet and exercise plans.
“Our study results suggest that if you are 25, you’d have to eat even less and exercise more than those older, to prevent gaining weight,” Jennifer Kuk, a professor of kinesiology and health science at Toronto’s York University, said in a statement. “However, it also indicates there may be other specific changes contributing to the rise in obesity beyond just diet and exercise.”
Note that the study utilized Body Mass Index (BMI), the accuracy of which is questionable. But if the findings are true, it has some pretty big implications about how much our social, dietary, and physical environments have changed, and what impact that is having on human health.
While the researchers are pretty cautious about what exactly accounts for this generational disparity, they mention three likely culprits.
First, people are exposed to more chemicals that might be weight-gain inducing. Pesticides, flame retardants, and the substances in food packaging might all be altering our hormonal processes and tweaking the way our bodies put on and maintain weight.
Second, the use of prescription drugs has risen dramatically since the ’70s and ’80s. Prozac, the first blockbuster SSRI, came out in 1988. Antidepressants are now one of the most commonly prescribed drugs in the U.S., and many of them have been linked to weight gain.
Finally, Kuk and the other study authors think that the microbiomes of Americans might have somehow changed between the 1980s and now. It’s well known that some types of gut bacteria make a person more prone to weight gain and obesity. Americans are eating more meat than they were a few decades ago, and many animal products are treated with hormones and antibiotics in order to promote growth. All that meat might be changing gut bacteria in ways that are subtle, at first, but add up over time. Kuk believes the proliferation of artificial sweeteners could also be playing a role.
I would also add that the high rates of anxiety and depression resulting from tougher economic times probably play a role, too; stress and sleeplessness are well documented contributors to weight gain, and a large proportion of young people report chronically experiencing these problems.
As in so many other studies about the causes of weight gain, it appears that the contributing factors are complex and poorly understood, involving a confluence of hormonal, dietary, and environmental influences we are just starting to understand. Hence why the study cautions about the prevailing negative attitude towards the physically unfit.
The fact that the body weights of Americans today are influenced by factors beyond their control is a sign, Kuk says, that society should be kinder to people of all body types.
“There’s a huge weight bias against people with obesity”, she said. “They’re judged as lazy and self-indulgent. That’s really not the case. If our research is correct, you need to eat even less and exercise even more” just to be same weight as your parents were at your age.
As someone who has endured a lifelong struggle to maintain a healthy weight, I never really considered whether or not my difficulties were part of a larger generational milleui. Being fit and healthy was always supposed to be a difficult endeavor, not least because it runs somewhat contrary to our biology (humans evolved to store fat at all costs, for example). But what happens when humans struggle to adapt to totally new diets and conditions? Our species is already taller and larger in overall mass than it was just a couple of centuries ago; how different will physically be another century or two from now?
