Act Your Age When Exercising

A few years ago, I had the opportunity to visit China and spend some time in Beijing. One of my favorite morning activities was to go to a public park close to my hotel. Initially, I just went for walks on my own, but soon I was invited by a small group of local seniors to join in their Tai Chi exercise. It was a first for me, so I had some learning to do, but everyone was extremely helpful and showed me the ropes. Although I didn’t continue practicing regularly after returning home, the message I received from the encounter stuck.

Tai chi ch’uan, as the exercise was originally called in China, is in fact a form of martial arts. However, unlike aerobic and weight training, its primary purpose is not to increase athletic ability but rather promote harmony between the physical and mental aspects of our being.

It’s not about being able to run marathons or lift hundreds of pounds. It’s not about winning in competition, says Arthur Rosenfeld, a tai chi master and author of “Tai Chi – The Perfect Exercise: Finding Health, Happiness, Balance and Strength.” It’s a more mature way of accepting one’s body, how it works and how it looks, and also about aging gracefully and with acceptance of one’s inevitable decline.

Much is being talked about the new way of aging as the Baby Boomer generation approaches retirement. Unlike their parents and grandparents, today’s retirees are not ready to spend their twilight years quietly. Those who have worked hard and played hard all their lives, we are told, will continue to do so – and many actually try. But that doesn’t mean we can defy the laws of nature forever. The fact that there are many more senior athletes who can run a marathon in their 70s and 80s doesn’t make aging a thing of the past. The fact that modern medical technology can treat most ailments and control symptoms nearly indefinitely doesn’t make us immune to disease. On the contrary, some studies have found that Boomers are aging worse than past generations in a number of respects.

Of course, staying physically active at any age is an important ingredient for good health. Exercising regularly can prevent many age- and lifestyle-related ills, including diabetes, heart disease, and also help reduce stress, anxiety and depression, according to the National Institute of Health (NIH).

Endurance and strength training continue to be important as the body ages, perhaps increasingly so. Stretching for flexibility and balance exercises to prevent falls should be added. The Centers for Disease Control and Prevention (CDC) recommend for older adults to spend at least 150 minutes on moderately intense aerobics and 60 minutes on resistance training per week.

Naturally, more time in the gym or on the bike path can yield higher benefits. But equally crucial is acting age-appropriately, knowing one’s limitations, avoiding injuries, and accepting (grudgingly) that things are not the same as they used to be. There is no point in denying nature taking its course.

What I learned from my brief encounter with the Chinese Tai Chi practitioners was that there can be joy in doing less and achieving little – such as finding pleasure in simply moving one’s body with grace and gratitude. Realizing that didn’t make me feel old, it made me feel rich.

In the Fight Against Obesity, Even Framing the Right Message Can Be Challenging

June 19th, 2013 at 2:54 pm by timigustafson
  • Comments

As obesity rates continue to rise rapidly in the United States and many other countries, health experts wonder how to convey more effectively the seriousness of the crisis to the public. While many seem to be resigned to the fact that the world population is getting heavier, the growing numbers of obese people are burdening health care systems in unprecedented ways.

Societies around the world are woefully unprepared for the changing realities and lack the resources to meet the coming challenges. Insurers and healthcare providers warn that the additional costs of treating millions upon millions of overweight patients are unsustainable.

Yet, despite the flood of obesity-related health messages in recent years, it has been proven difficult to create a sense of urgency in the public’s perception of the issue. One study found that obesity-related media campaigns can be perceived as motivating but also as discouraging and even stigmatizing.

When participants in this study were asked to view obesity awareness programs from the U.S., England and Australia and rate them based on their responses, most favored positive messages that recommended making small improvements over negative ones that laid blame squarely on the lack of personal responsibility.

But not everyone agrees with taking a soft approach. “A shock of recognition” is in order because we “need to understand that obesity is a national health problem, one that causes lethal diseases, shortens lives and contributes substantially to rising health care costs,” warns Dr. Daniel Callahan, a bioethicist and cofounder of the Hastings Center, a think tank specializing in bioethics in the public interest.

A report he authored recently, titled “Obesity: Chasing an Elusive Epidemic,”, has quickly evoked fierce protests from obesity acceptance and antidiscrimination advocates, mainly because of his suggestion that social stigmatization and shaming could be a useful tool in the fight against the obesity epidemic. Similar measures, he points out, have been highly successful during the anti-smoking campaigns a few decades ago.

Trying to get the obesity crisis under control has turned out to be “the most difficult and elusive health problem this country has ever encountered” Callahan laments. Addressing it effectively requires profound changes in our personal behavior but also in the ways we allow food and beverage commerce to operate. The respective industries spend billions of dollars on marketing less-than-healthy products, often aimed at children, and on lobbying to prevent much needed regulations from being enacted.

There are limits to how much government can do to influence people’s behavior. But government can impose regulations and taxes to coerce both industry and consumers into making changes that can produce desirable results over time.

And here we can indeed take cues from the anti-smoking crusades. For instance, we don’t allow smoking in most public areas and means of transportation any more. We certainly don’t allow cigarettes to be sold to minors. We no longer have cigarette advertisements on television. Placing warning signs and sometimes deterring images on cigarette packages is mandatory. High taxes on tobacco products have made them less affordable. Considering how dramatically smoking has declined in this country, these measures have turned out largely successful.

The question is whether there will be enough political will to take similar steps towards the causes of obesity. For instance, can we agree to ban fast food outlets from residential areas? Can we forbid the sale of junk food to minors unaccompanied by adults? Can we outlaw TV ads for snacks and sodas, at least during daytime hours? Can we impose high taxes not only on sodas but also on unhealthy foods and snacks to curb consumption? Can we require warning signs on packaged foods containing unhealthy ingredients?

Proposals like these may sound radical and outlandish now. But the same was said about the smoking restrictions we take for granted today. Some of the measures mentioned here are in fact already being experimented with. What’s most important is that we finally convey a consistent message that doesn’t confuse us any longer about what we should and what we shouldn’t do.

Vegetarians May Have Longer Life Spans Than Meat Eaters, Study Suggests

June 16th, 2013 at 2:55 pm by timigustafson
  • Comments

It is common knowledge that eating healthy is conducive to our well-being, including our natural aging process. But can adherence to a vegetarian diet actually add to our life span? One study published in the Journal of the American Medical Association (JAMA) found evidence that vegetarians have a slightly better chance at living longer than omnivores.

There are clearly beneficial effects of vegetarian diets in the prevention of chronic diseases and the improvement of longevity, according to Dr. Michael Orlich of the Loma Linda University Medical Center in California, the lead author of the study report.

For the study, the researchers interviewed over 70,000 participants about their eating habits. Those who identified themselves as vegetarians were divided into different categories of vegetarianism, including vegans (eating nothing but plant foods), lacto-ovo vegetarians (eating plant-foods as well as dairy products and eggs), and semi-vegetarians (eating mostly plant-foods but also some animal products like fish and poultry).

Using national databases, the researchers then determined differences in mortality rates during a follow-up time of six years. They found that over one year five to six per 1,000 vegetarians had died compared to seven per 1,000 meat eaters.

Since all causes of death were included in the analysis, it is not altogether clear what made the differences in the mortality rates, but critics have pointed out that the vegetarian groups had other health-promoting advantages as well such as overall healthier lifestyles, abstinence from smoking, lower average body weight and higher education levels than their omnivorous counterparts. But the vegetarians also tended to be older.

Still, the study’s findings confirm that people who eat mostly plant-based foods are less likely to develop chronic diseases like heart disease, diabetes and certain forms of cancer.

So, should we all consider becoming vegetarians for the sake of a longer life? Not necessarily. Longevity is not dependent on just one aspect of our existence but rather on all the things we do for the benefit of our well-being. You may eat all the health food you want, but if you have a hard time handling your stress at work or at home, it will still affect your heart. If you put off exercise for too long, you can gain weight on a vegetarian diet as well.

The trick is to understand that all our actions are interconnected. If we get run down in one area, it has consequences for all the others. I know that if I don’t eat right, I feel sluggish and without energy. The same happens if I don’t get enough physical activity or I’m sleep deprived. If my mind is not stimulated and I’m bored, I lose focus. If I allow myself to get stressed out, it impacts my work as well as my relationship with family and colleagues.

So, of course, it’s a good idea to eat foods that offer the greatest benefits and the least detriments in terms of good health and perhaps also a longer life. But the point is that it has to come in one whole package called healthy living. As I have emphasized many times before, longevity alone should not be the goal, but the highest possible quality of life to the very end.

The Healthiest Places to Live in the U.S.

June 8th, 2013 at 5:17 pm by timigustafson
  • Comments

How healthy you are depends largely on the diet and lifestyle choices you make. It also matters how educated and financially secure you are. And where you live – not only in what kind of neighborhood but also in which part of the country – plays a role as well.

If you are looking for the most health-promoting environment in America today, Minneapolis, Minnesota, is the place to be, according to a survey conducted by the American College of Sports Medicine (ACSM), titled the American Fitness Index™ (AFI).

The report, which has been issued annually since 2007, measures the state of health and fitness at the community level throughout the U.S. Among the considered factors are opportunities to exercise and be physically active, including access to safe sidewalks and bike paths, athletic facilities, playgrounds, public parks and so on.

“What Minneapolis does so well – they are firm believers in the ‘if you build it, they will come’ attitude,” said Dr. Walter Thompson, a professor at Georgia State University and chair of the AFI advisory board in an interview with NBC. “They spend a lot of money on their parks. They spend $227 per capita on their parks. […] So you can see they put their money where it needs to be to create a healthy environment,” he added.

By contrast, the least proactive places in terms of fitness promotion on the AFI list spend about $62 per capita on parks and other recreational facilities.

Runner-ups were Washington D.C., Portland, Oregon, and San Francisco, California. Seattle, Washington, came in eighth.

The existence of public parks is an especially important indicator because it provides people with the lowest hurdle preventing them from exercising. Unlike many sports facilities such as gymnasiums, swimming pools, basketball courts, running tracks or golf courses, parks don’t require memberships or have limited opening hours.

When you provide the environment for people to exercise, there is no excuse to be a couch potato, said Thompson. And that translates to lower personal health indicators such as obesity and diabetes as well as poor lifestyle choices like smoking.

Minneapolis was also found to be especially conducive for the health of seniors. According to the United Health Foundation’s America’s Health Ranking Senior Report, more older people report being in very good to excellent health in Minnesota than in all other states. Also, the poverty rate among the elderly is lower here than elsewhere.

The aspect of senior health in our communities is of growing importance because the baby boomer generation, a large segment of the population, is about to retire. It is also a group of people plagued by considerable health problems, many due to less-than-perfect lifestyle habits. Creating environments that allow for the betterment of their health status is in all our interest and should be given much attention.

Eating Barbecued Foods May Increase Cancer Risk, But You Can Take Precautions

June 5th, 2013 at 2:47 pm by timigustafson
  • Comments

Barbecuing in the backyard during the summer months is a celebrated tradition in millions of American households. Putting a few hamburgers, hot dogs or steaks on the grill is an easy way to throw together a tasty and fun meal, and also a great opportunity to socialize with family members and friends. Unfortunately, the typical barbecue foods are not the healthiest, especially when prepared improperly. Health experts have long warned that consuming grilled meats may be linked to an increased risk of cancer.

The reason is that when meat products are cooked over high temperatures or touched by flames and smoke, they form certain chemical compounds, specifically Heterocyclic Amines (HCA) and Polycyclic Aromatic Hydrocarbons (PAH), which are deemed to be carcinogenic.

HCAs, also found in cigarette smoke, have been reported to cause cancer in a number of inner organs, including the stomach and liver, and also the skin. PAHs, the second type, form when meat juices drip onto coals or other hot surfaces, creating smoke. The carcinogens in the smoke then attach themselves to the outside of the foods they come in contact with.

“The cancer risk from grilling is real,” warns Karen Collins, a registered dietitian who serves as an nutrition advisor to the American Institute for Cancer Research (AICR). “But it changes dramatically with what you grill and how you do it,” she says.

There are substances in the muscle proteins of animal food products – whether it’s red meat, poultry or seafood – that react under high heat to form these carcinogenic compounds that can damage the DNA of human genes, potentially leading to cancer development, she explains.

The most common risks in connection with HCAs are cancer of the colon and the stomach. According to Collins, studies have shown that consumption of barbecued red meat almost doubles the risk of growing colon polyps, which can lead to colon cancer. Since carcinogenic compounds travel through the bloodstream, tissues in other parts of the body can be affected as well.

Thankfully, such risks can be mitigated by employing better grilling techniques and perhaps by changing some ingredient choices.

Barbecuing, especially when using a charcoal grill, produces the highest amount of HCAs, according to researchers at the University of California, Davis, Cancer Center, who conducted studies on the subject. Using a gas grill instead, or pan-frying and broiling are somewhat safer but not by much. Baking, poaching, stir-frying and stewing, they say, are considerably less harmful.

Other preventive steps barbecue lovers can take are lowering the heat and making sure the meat does not get charred, or the charred parts get trimmed off. Some recommend zapping meat cuts in the microwave for 30 to 60 seconds beforehand to shorten the time of exposure to open fire.

What kind of food you barbecue also makes a difference. By contrast to animal foods, plant foods don’t develop HCAs when heated. Mixing both, for example in form of kabobs, can cut the risks substantially. Marinating before grilling is also believed to be helpful because it puts an extra layer of coating on the food that can prevent overcooking and charring.

Wrapping grill food in aluminum foil, on the other hand, is not recommended, since the exposure to metal under intense heat can produce its own set of health hazards.

The bottom line here seems that barbecuing can be a reasonably healthy cooking method if done right and enjoyed in moderation. And this can be said about almost anything we do with food.

Your Fruits and Vegetables May Not Be as Healthy as You Think

June 2nd, 2013 at 4:42 pm by timigustafson
  • Comments

“Eat your fruits and vegetables” is not only your mother’s advice for your nutritional health but also the core message of the Dietary Guidelines for Americans, the official recommendations by the United States government for how its citizens should eat to stay healthy and slim.

“Healthy diets rich in fruits and vegetables may reduce the risk of cancer and other chronic diseases,” say the Centers for Disease Control and Prevention (CDC). Those other chronic diseases plague two thirds of our population and, increasingly, the rest of the world. Weight problems, diabetes, heart disease and hypertension keep spreading like wildfire around the globe and are killing tens of millions of people every year, according to the World Health Organization (WHO). These are mostly diet and lifestyle related ills, and much of the havoc they wreak could be avoided by changing our eating habits to what they once were before fast food and TV dinners. At least, that’s the thought.

While everyone seems to agree that eating fruits and vegetables is good for you, there is precious little knowledge among the public of what exactly makes fresh produce so beneficial. So, here are a few basic facts.

Fruits and vegetables are good sources of carbohydrates, a main component for dietary balance and health. Carbohydrates deliver energy to many bodily functions, including the brain and the nervous system. There are two groups of carbohydrates: simple and complex. Simple carbohydrates are provided by many fruits and also refined sugar. The complex kind are the ones you should opt for. Those are found in whole grains, starchy vegetables and legumes.

Fruits and vegetables also contain many vitamins and minerals. There are two categories of vitamins: fat-soluble, which get stored in the fat tissue, and water-soluble, dischargeable in the urine. Both are essential for growth, development and body functions. Minerals are important for the health of organs, tissue, bones, muscles and cells.

Fruits and vegetables are high in fiber, a carbohydrate, which paradoxically cannot be digested but is nevertheless important for the digestive process. A fiber-rich diet is believed to prevent cardiovascular disease and diabetes as well as certain types of cancer (although the latter has been disputed).

Fruits and vegetables are the main source of carotenoids (as in carrots) in most people’s diet. Carotenoids are responsible for the bright colors staring at you in the produce department and are believed to be highly beneficial, especially for eyesight.

Part of the nutritional value that sets fruits and vegetables apart are phytochemicals and antioxidants. Phytochemicals are plant chemicals whose multiple advantages are still being discovered. Antioxidants are substances that are believed to protect the body from so-called “free radicals,” metabolic byproducts that can cause cell damage, possibly leading to certain forms of cancer.

Unfortunately, many of these enormously valuable characteristics of the fruits and vegetables we commonly consume today have been diminished or altogether lost over time due to modern breeding and farming methods. In a recent article published in the New York TimesJo Robinson, an investigative journalist and author of “Eating on the Wild Side: The Missing Link to Optimum Health” (Little, Brown & Co, 2013), reported on the substantial nutritional losses in our produce over the past 50 to 100 years. Because we largely abandoned gathering wild plants in favor of growing them domestically, she says, many of the nutrients were bred out to increase flavor and yield.

“Unwittingly, we have been stripping phytonutrients from our diet since we stopped foraging for wild plants some 10,000 years ago and became farmers,” she writes. “Throughout the ages, our farming ancestors have chosen the least bitter plants to grow in their gardens. It is now known that many of the most beneficial phytonutrients have a bitter, sour or astringent taste. […] The more palatable our fruits and vegetables became, however, the less advantageous they were for our health.”

As a case in point, Robinson points out that corn, the way we prefer it today, namely sweet and of light or almost no color, has only a small fraction of the nutrients its ancestors had to offer.

“After reducing the nutrients in the majority of the fruits and vegetables we eat today, how can we recoup the losses,” she asks. Thankfully, there are still a few species around that have survived more or less intact, among them arugula salad leaves, green onions and a variety of herbs, now mostly used to enhance taste but still adding nutritional value.

In the end, of course, we have to work with what is available to us today. Compared to our dismal choices that dominate the so-called “Western diet,” consisting mainly of animal products and highly processed food, filling our plates with fruits and vegetables as much as possible remains the next best thing we can do to keep us healthy and properly nourished.

Why Taking Vacations Is Important for Your Health

May 29th, 2013 at 7:55 am by timigustafson
  • Comments

Memorial Day weekend used to be the traditional kickoff for summer getaways. But for millions of Americans, going on a vacation or even taking a few days off here and there is a luxury they can ill afford. Among the 20 most developed countries in the world, the United States ranks dead last when it comes to recreation.

Unlike in Europe, where paid vacations of 20 to 30 days annually are the norm and guaranteed by law, the labor standards in this country generally do not require employers to provide such benefits. What’s more, even those lucky Americans who are entitled to paid time off often forego part of it.

There is no doubt that American workers, including millions of immigrants who have chosen the American way of life, have a particularly strong work ethic. But countries like Sweden or Germany, not exactly known as slackers, have fared well with their mandatory vacation policies, without losing their competitive edge. In fact, according to the latest report on global economic competitiveness by the World Economics Forum, the U.S. came in only fourth behind Switzerland, Sweden and Singapore. And even Canada, a country that is arguably closest to us in culture and lifestyle, mandates a minimum of 10 days vacation time per year for all its workers.

So, what makes Americans so much less inclined to quit work and relax for a few weeks or even just days on end?

For low-income workers it’s primarily a question of money. Those are typically the ones with the least benefits, including paid vacation or sick leave time. For others it’s fear they could be passed over for promotions or even lose their jobs if they are absent too often or too long. Some think it’s not worth the extra hassle to tie up loose ends before they leave or catch up after they return. And there may be a few who just don’t know what to do with themselves outside of work.

What’s often not discussed is that not taking time off regularly can lead to serious health problems. The results are comparable to chronic stress, when there is no reprieve not just from one’s workload but also from repetitive routines.

Often people get into a mindless routine at work and home, which can be broken if they distance themselves once in a while, says Dr. Ellen Langer, a psychology professor at Harvard University, in an interview on the health benefits of vacationing and travel with CNN. Uninterrupted routines tend to result in boredom, which hinders creativity and mindfulness, she says, and is therefore counterproductive. By contrast, having new and interesting experiences on a trip, for example, can be brought back to the workplace and enhance one’s performance.

But it’s not just mental health that must be restored on occasion. Chronic stress takes its toll on the body’s ability to resist infections, maintain vital functions and even the ability to avoid injuries, according to Dr. Susan Krauss Whitbourne, a professor for psychology at the University of Massachusetts Amherst and contributor to Psychology Today.

“When you’re stressed out and tired, you are more likely to become ill, your arteries take a beating, and you’re more likely to have an accident. Your sleep will suffer, you won’t digest your food as well, and even the genetic material in the cells of your body may start to become altered in a bad way.”

And mentally, she says, “not only do you become more irritable, depressed and anxious, but your memory will become worse and you’ll make poorer decisions. You’ll also be less fun to be with, causing you to become more isolated, lonely and depressed.”

For these reasons and others, your vacation, should you decide on taking one, must not end up causing you even more stress.

If you travel somewhere away from home, I recommend choosing a destination that is truly different from your familiar surroundings. It doesn’t have to be a deserted island, just unlike what you’re used to.

Leave your smart phone and laptop behind, so you cannot be reached from the office and won’t be tempted to “check in” every so often.

Don’t get involved in too many activities, even though they seem fun, if they turn your vacation into another hectic event.

Live in the moment and make the most of each day. Focus on all the things you never seem to have enough time for such as leisure, pleasure, conversation, etc.

If all or most of this seems impossible to you, perhaps it’s time to rethink your priorities.

Can Travel Make You Smarter?

May 26th, 2013 at 7:34 am by timigustafson
  • Comments

I never feel more enlightened, more inspired, more educated than when I travel, especially to far-flung and exotic places. Without fail, I come back a different person, feeling enriched and full of gratitude for what life has to offer.

That travelling can broaden our horizon, both literally and figuratively speaking, is nothing new. As Mark Twain once famously said, “Travel is fatal to prejudice, bigotry and narrow-mindedness.” But can it also improve our mental capacities? Scientists in Germany, who conducted a recent study of how our minds respond to new experiences that come with travel and exploration, say yes. And it does not only apply to humans. Even the tiny brains of lab mice seem to benefit from roaming around.

For the study, the researchers kept 60 adult, female, genetically identical mice in a large enclosure that provided what they called an “enriched environment” where multiple objects and arrangements challenged the animals to interact with unfamiliar and changing surroundings. They divided them in three groups, one of which they exposed to the richest environment, providing numerous learning opportunities; the second group was limited to smaller, much less stimulating spaces; the third was used as the control group. To measure the amount of encounters with new events each group faced for the duration of the experiment, a total of 105 days, the mice were outfitted with tracking devices and monitored with sensors placed all around them.

As it turned out, the group that was allowed the most exploratory activity clearly developed a greater amount of hippocampal neurogenesis, meaning they showed significantly more activity in the hippocampus, a region in the brain that is primarily responsible for learning, than their less adventurous, more homebound counterparts.

“Those who move around a lot have many more experiences,” said Dr. Gerd Kempermann, a neurologist and one of the authors of the study, in an interview with the German newsmagazine Der Spiegel. “The brains of active individuals produce additional neurons in anticipation of more experiences to come and to deal with them effectively.”

What are the implications for us humans, if any? “If experiences and lifestyle choices have such a great influence on the individual structure of the brain in mice, chances are that this happens for us even more so,” Dr. Kempermann added.

Other clinical studies have long suggested that stimulating the mind through lifelong learning can slow down, if not prevent, age-related mental decline like memory loss and dementia. A high level of education acquired early in life seems to be of advantage as well because already established neural connections become reinforced with later learning, a process that is known as “neural redundancy.”

Obviously, filling one’s passport with more stamps by itself does not add more IQ points. But openness and curiosity, the willingness to question old views and convictions, and seeing the world from different angles can keep us young at heart, which includes the mind.

For many generations, immigrants from all over the world have come to the United States hoping for greater opportunities and better living conditions compared to their home countries. Through hard work and frugal spending they aimed for “the American dream” of prosperity and happiness, if not for themselves, then for their children and grandchildren. Many succeeded. But for many more it turned out to be an elusive mirage.

Tales of rags to riches, or at least of humble beginnings to comfortable living, are a solid part of our national narrative and are told in countless versions, often laden with romanticizing overtones. But historically speaking, this has always been the exception rather than the rule.

With growing income inequality over the past few decades, the notion of the American dream for all has lost ever more of its luster. Becoming an American nowadays may not only disappoint you in terms of your socio-economic prospects, it may even be bad for your health, according to several recent studies on the subject.

“A growing body of mortality research on immigrants has shown that the longer they live in this country, the worse their rates of heart disease, high blood pressure and diabetes,” a report on the health toll of immigration in the New York Times concludes.

In terms of diet and lifestyle, assimilation among newcomers does not happen too slowly, it happens too fast, some experts say. The standard American diet (SAD), which is not particularly conducive to anyone’s health, seems to affect immigrants at disproportionally higher rates. Eating processed foods that have little nutritional value and are high in fat, sugar and salt content is common especially among poor immigrants because of low cost and convenience.

“In Mexico, we ate healthily and didn’t even know it,” said one immigrant who had become diabetic since her move to the U.S. “Here, we know the food we eat is bad for us. We feel guilty. But we eat it anyway.”

Even more disturbing is that the second generation – the children of immigrants born and raised in the U.S. – doesn’t seem to fare better but worse. Although American-born children of immigrants are on average better off financially, they often have a shorter life expectancy than their parents. The reasons for this are not altogether clear, but experts believe that poor diet and lifestyle choices as well as a widespread lack of education in health matters may play a role.

To shed some light on these health disparities, the Centers for Disease Control and Prevention (CDC) issued a report in 2011 that investigated economic, racial/ethnic and other social factors such as healthcare, exposure to occupational and environmental hazards and behavioral risks, among others.

The CDC researchers found that health education together with access to healthcare and preventive health services would have the greatest impact on reducing health disparities between immigrants and the rest of the population. For school children, enrollment in breakfast and lunch programs may also be effective.

The U.S. is by no means the only country that struggles with addressing the health problems of immigrants. A report published in the Canadian Journal of Public Health (RCSP), the official publication of the Canadian Public Health Association (CPHA), found that even newcomers to Canada who were well educated in their mother tongue still faced substantial barriers because of lacking language skills and understanding of cultural differences, affecting them on multiple levels, including their health. A panel of experts at the CPHA recommended a health literacy strategy for immigrants with English or French as a second language, as well as training programs for healthcare providers to increase awareness of their diverse clientele’s needs.

Reintroducing Cooking in American Households an Unlikely Prospect, Study Finds

Americans don’t like to cook. They don’t want to spend the time it takes for food shopping, food preparation and clean up, especially when it’s so much easier to stop for a quick bite at a restaurant or drive-thru or bring home some take-out. Yet, experts are convinced that making home cooking fashionable again would be one of the most effective steps we could take to address the nation’s obesity crisis.

The United States ranks at the bottom of industrialized countries not only in terms of time spent on meal preparation but also on consumption, according to surveys conducted by the Organization for Economic Cooperation and Development (OECD), an international group that analyzes economic data worldwide. In other words, we not only don’t cook, we also don’t set much time aside to enjoy our food. Instead, more and more of us skip breakfast, work through lunch and sustain ourselves throughout the day by snacking.

The percentage of calories from snacks in the American diet has doubled since the 1970s, as more people have turned into all-day grazers while foregoing sitdown meals on most days, a study by the National Health and Nutrition Examination Surveys (NHANES) found.

Over half of American adults say they have three or more snacks a day. Almost a third of children and adolescents eat chips, popcorn, pretzels and the likes on a daily basis. The amount of pizza eaten, both in restaurants and at home, has nearly tripled over the past thirty years. Meanwhile, the number of calories in pizzas has increased by 25 percent on average since the late 1970s. Over the same time period vegetable consumption has declined from 2.6 to just 1.9 servings per day – and that includes French fries.

The easiest way to turn these developments around would be to start preparing our meals from scratch again, says Mark Bittman, food writer and author of “Cooking Solves Everything: How Time in the Kitchen Can Save Your Health, Your Budget, and Even the Planet” (Kindle edition, 2011). Millions of Americans don’t ever cook. The rest cooks on occasion, often just microwaving. Many don’t bother with sitting down at the dinner table but rather eat in the car, at a counter, or in front of a screen. “And that’s a shame, because cooking is a basic essential, worthwhile and even enjoyable task,” he writes.

Bittman applauds others who are trying to get the message out about the many benefits of home cooking, like his fellow-book-author Michael Pollan who just published a new book on the same subject, titled, “Cooked: A Natural History of Transformation” (Penguin Press, 2013). In a review on the then upcoming publication he writes: “Cooking is probably the most important thing you can do to improve your diet.”

The reasons are obvious. If you are in charge of the ingredients that go into your food, you already are going to eat better because you won’t include extra fat, salt, sugar, preservatives, dyes and other additives. You also won’t eat as many highly caloric items like French fries, which are cumbersome to make at home. The same goes for pizza (made from scratch, not the ones you just heat up).

One of the central problems with cooking is that we don’t value it enough any more. We are used to having tasks like these done for us by outside service providers. But unlike getting your car or computer fixed by someone else, cooking is much more intimate. It connects us with our bodies, nature and loved ones.

Michael Pollan even thinks that the experience of cooking brings us closer to the most basic elements that surround us: fire, water, air and earth and also tightens our social and ecological relationships. All that has deeply transformational characteristics that can change us on multiple levels, but all for the better.

That is much to hope for – perhaps too much. Still, it is a fact that an increasing number of people are looking for ways to eat more healthily and also reduce stress on the environment, e.g. by cutting back on meat consumption and buying more produce from local farms. A rediscovery of home cooking would fit squarely within these trends. Whether it will be enough to transform or currently predominant way of life remains doubtful.
