On the latest Global Pulse Episode, host Erin Coker examines media coverage of rising obesity rates around the world. Watch the episode below and share your thoughts!

I, like many (well, most) Americans have had issues with my weight. After going off to college in 2004, I noticed my weight beginning to climb until I started feeling unhealthy. I tried dieting and adding more exercise to my daily routine, but the extra weight stayed on. Then something miraculous happened: I left the country. During my year of study abroad, my waistline shrunk. Was I beating myself up about keeping to a certain number of calories a day? Did I take up an intensive exercise schedule? Not at all. So, what explains the weight loss?

In a word, culture. Although diet, exercise, and body chemistry are the critical factors in determining body weight, there is evidence that one's culture plays a huge role (pardon the pun) when it comes to obesity. While America is known worldwide for obesity problems, it isn't technically the most obese nation on earth. According to Forbes, that distinction goes to the tiny island nation of Nauru with a remarkable 94.5 percent of its population overweight. In fact 8 out of the top 10 overweight nations are located in the South Pacific. Part of the reason for this may be genetic, but part of the cause is the widespread poverty on these islands and the dependence on imported foods. Highly processed foods imported from the west are a cheap sources of calories; unfortunately they're also the unhealthiest. Cultural factors, including, "[the] notion that 'bigness' is a sign of wealth and power" also contribute to a culture of obesity which has left the South Pacific the fattest region in the world. Is America, like the South Pacific, a victim of having a culture of obesity? We certainly don't equate 'bigness' with wealth and power - quite the reverse, if our celebrities and icons are any indication.

Which brings me to France, the country in which my weight-loss miracle occurred. While the United States and the South Pacific are two of the world's fattest regions, France is championed for its low national obesity rate. How do the French, with a diet rich in carbs, fats, and oils, stay so thin? Researchers have called this the French paradox.

But the French paradox really isn't much of a paradox at all. When it comes to how French citizens stay thinner than Americans, both the quantity and quality of food consumed makes the difference. French consumers typically eat less processed food than their American counterparts, and when they do indulge in fats and sweets, they generally eat smaller portions. In my personal experience, I found processed junk foods to be more expensive in France than fresh fruits and vegetables - where in American supermarkets, the situation is often the opposite. America also has a 24 hour fast food culture with opportunities to eat just about anything at anytime, anywhere. In France, the majority of supermarkets are closed by 9PM - and you can't get a decent burrito anywhere.

So do I really attribute my weight loss to a geographical change? In many ways, I do. When I was surrounded by a culture whose values about food and eating promoted a healthier way of life, I found myself behaving like those around me. Think of it as positive peer pressure. This is not to say that all is perfect in the land of foie gras and baguettes. The French, like many cultures worldwide, are beginning to grapple with their own obesity problem as the fast-food culture spreads.

So how is my weight now that I'm back in the US? In 1.5 years, I've gained back most of what I lost in France. I can't blame America, though. In France I was able to change my lifestyle so I could eat fresher, smaller, and more slowly. I learned the right way to eat, but I just started to get lazy once I returned to a culture where it's a little harder to do so. Oh well, I gotta go... the pizza delivery guy is here.

For this week's Global Pulse episode, Swine Flu: The Vaccination, host Erin Coker asks, Will you get vaccinated? Share your thoughts and watch this episode below!

When I first learned of swine flu, I dismissed the general reaction as unnecessary panic over something no more threatening than – well, catching the flu. Inconvenient and uncomfortable, but hardly the second coming of the 1918 influenza pandemic.

Then I caught the H1N1 virus myself. After being diagnosed, I took comfort in the fact that, according to the Centers for Disease Control and Prevention, of the estimated 1 million Americans believed to have been infected with the virus between April and June, only about 593 have died. To provide a bit of perspective, seasonal flu can result in up to 500,000 deaths worldwide each year. So if you do get swine flu, chances are it will not kill you, or even result in serious symptoms. I am living proof, although there were times over the last week when I wasn’t so sure.

"Uncomfortable and inconvenient" is an understatement. I am a generally healthy young person, but I was immobilized by a high fever, chills, severe muscle pain and fatigue. I would be dishonest if I said that there weren't a few scary moments when I felt compelled to inhale deeply to make certain my lungs were still working. The normally benign shadows on my ceiling took on a menacing hallucinatory quality. Would ever feel like myself again?

Six days of bed rest, fluids and the antiviral Tamiflu later, I am starting to feel better. So, have my feelings about swine flu changed? Yes and no.

As ABC News reported earlier this week, thousands of people have contracted swine flu in recent months and have made a full recovery. Global mortality rates to date are lower than those associated with seasonal flu -- the World Health Organization (WHO) reports 2,837 H1N1 deaths worldwide -- but health experts have noted that H1N1 may cause more severe illness and death in younger adults and children than does the seasonal flu. Reuters reported that the WHO has also warned of a severe strain of swine flu that can cause acute respiratory illness in otherwise healthy young people.

More disturbing is the potential threat to developing countries, which often lack the resources to produce vaccines. A recent report released by a UK-based global risks intelligence firm (PDF) notes that while Western nations may be at the greatest risk of spreading H1N1, they also have significant resources to contain the proliferation of the virus. In contrast, Sub-Saharan Africa stands out as the area least able to contain an influenza pandemic. Underdeveloped health facilities and the difficulty of accessing doctors in rural areas could pose further risks to vulnerable populations.

Nonetheless, as I read recent reports warning of a more aggressive second wave of H1N1, or speculations of a deadly mutated super virus, I recall what Indian blogger Hariharan Krishnamurthy wrote in mid-August after a swine flu outbreak killed 20 people in Mumbai and in the western city of Pune: "There is a mass hysteria about the swine flu... The news channels are adding fuel to the fire... and newspapers showing only the negativity... I am not trying to undermine the seriousness of the issue but also so much panic is also not at all required."

A good reminder that prudence and preventative measures are best combined with a healthy dose of perspective.  Take it from one of the latest statistics.

Health care reform is the hottest topic in U.S. news media this summer. One question that arises in this debate is whether the government should spend the money to overhaul the old system, or use the money to pay off federal deficits?
 
As one of the 47 million uninsured Americans, I think that the health care system in the U.S. is terrible. I earn barely enough to cover my expenses, and at the end of the month, I am left with very little extra cash to spend on something as important and necessary as health insurance.
 
I looked into buying insurance, and since I’m very healthy with no prior medical conditions, I expected to see insurance premiums of $50 - $85 a month. I was shocked to find that the lowest premiums started at $150 - $200, excluding dental or vision!! There was no way I could afford those prices.
 
Fortunately, I live in San Francisco, a very conscious and progressive city, where two years ago the City and County introduced a program called "Healthy San Francisco." This program covers primary care for all city residents, and the pay structure is based on income. I have now been with this program for one year and, although it doesn’t include major medical care, I’m happy.
 
But I began to wonder what would happen if I broke my leg. Would I be able to afford the hospital bills, or would they bankrupt me? A survey by the Kaiser Family Foundation [PDF link] found that: "Every week, thousands of Americans file for bankruptcy related to medical costs [and] 42% of adults report having problems accessing health care due to cost." I definitely favor a system of health care that benefits everyone, especially those that cannot afford it. After all, the rich will always be able to afford health care whether it is universal or not.

Here’s a cartoon that says it all.
 
How do other developed countries manage their citizens’ health care? PBS Frontline’s "Sick Around the World" website describes how five of the world’s developed nations go about taking care of their sick.
 
A completely socialized health care system might not work in the U.S., but universal care with regulated options that are based on fair-market values just might work. While providing access to all, it will create motivation for insurers and providers to offer the best service they can.

China's economy is slowing as it is the world over. One cause is the dramatic recent drop in U.S. consumption of Chinese imports. But nearly every day now, we are reading of deals struck by China that promise to turn the economic tide in Beijing's favor.

In Latin America and Vietnam, Chinese firms have signed deals to expand natural resource production. The New York Times reports that deals made in recent weeks in Venezuela, Ecuador, Argentina, and Brazil include terms designed to decrease demand for the U.S. dollar. From Vietnam, TIME interviews locals fearful that China's plans to mine bauxite will result in devastating environmental and job losses.

China's military is also assuming a more aggressive stance. The state navy hints that it may soon develop an aircraft carrier and expand its global missions along the lines of recent anti-piracy sorties in the Gulf of Aden.

The Economist though predicts China could chart a more peaceful route to recovery. This scenario would include long-term investment in domestic priorities such as public transit and health care. Chinese officials are reportedly "fascinated" by European models of welfare and public health, and could cooperate with the EU on future projects.

Can China achieve economic recovery in a manner that is peaceful and sustainable? Or should we remain skeptical of a world shaped by Chinese priorities?
