Yet another reason to avoid the typical western diet: eating high-fat, highly processed junk food filled with added sugars can impair brain function and lead to overeating in just one week.

A new report from The American Cancer Society has identified the largest single-year decline in the U.S. cancer death rate to date, likely spurred by new treatments and reductions in smoking.

One of America's already widespread health issues is projected to worsen over the next decade, as new research from the Harvard T.H. Chan School of Public Health suggests that almost half the adult population in the U.S. will be obese by 2030.

People with obesity, high blood sugar, high blood pressure or high cholesterol are often advised to eat less and move more, but our new research suggests there is now another simple tool to fight off these diseases: restricting your eating time to a daily 10-hour window.

From ear infections to loss of intelligence, it's become increasingly clear that air pollution can affect more than just our lungs.

Now, a study from University of Southern California researchers suggested that early exposure to traffic pollution increases the risk of childhood obesity in later life, adding more evidence that dirty air is a public health threat to children.

Coca-Cola

Coca-Cola intentionally funded the Global Energy Balance Network (GEBN) as a "weapon" in a "growing war between the public health community and private industry" on the causes of obesity, according to a press release sent to EcoWatch by consumer group U.S. Right to Know.

The quotes come from documents obtained in a Freedom of Information Request filed by U.S. Right to Know that formed the basis for a study published Wednesday in the Journal of Epidemiology and Community Health. The study's authors focused on the documents because they definitively proved that Coca-Cola funded the GEBN with the intention of influencing public health debate in their favor.

If Americans knew exactly how much added sugar came with the food and beverages they and their families consume, many might make different choices.

A coalition of public health organizations is calling on the federal Food and Drug Administration (FDA) to require that food labels display information on added sugar.

“While current regulations stipulate what foods can be labeled ‘No Sugar Added’ or use a similar phrase, there is currently no requirement that added sugars be shown separately on the ingredients list,” the group wrote FDA Commissioner Margaret Hamburg. “We recommend that FDA require that added sugars be listed on the ingredients section of food labels so that consumers can make healthier choices when they shop.”

According to the American Heart Association, which signed the letter to Hamburg, Americans’ average intake of added sugars is around 22.2 teaspoons per day, or 355 calories. The AHA’s daily-recommended limit for added sugar is 100 calories for women, and 150 for men.

Research by the federal Centers for Disease Control and Prevention has found more than 33 percent of adults and roughly 17 percent of children and adolescents living in the U.S. are obese.

“Many in the sugar and food industry like to encourage personal responsibility over government regulation of food and ingredients,” the coalition wrote. “Without specific information on the amount of ‘added sugars’ on the labels of food products, consumers can hardly exercise that responsibility and make smarter choices in the grocery aisle.”

Late last year, EWG reviewed the sugar content for more than 80 popular cereals market toward children and found most loaded with the ingredient. In fact, a one-cup serving of the Kellogg's Honey Smacks brand packs more sugar than a Hostess Twinkie, and one cup of any of the 44 other children’s cereals has more sugar than three Chips Ahoy! cookies.

The following organizations signed the letter to Commissioner Hamburg:

Environmental Working Group, 
 American Association for Health Education, American Heart Association, 
Center for Science in the Public Interest, Corporate Accountability International, 
Defeat Diabetes Foundation, 
American Association for Health Education, National Association of School, Nurses
Young People’s Healthy Heart at Mercy Hospital, Indiana Rural Health Association, 
American Society of Bariatric Physicians, 
The FGE Food & Nutrition Team, and Cambridge/Somerville WIC
and Iowa Public Health Association.

Rep. Rosa DeLauro (D-Conn.), the ranking Democrat on the House appropriations subcommittee responsible for funding the FDA, has called on the agency to disclose added sugar.

Food Politics

By Marion Nestle

Nature, the prestigious science magazine from Great Britain, has just published a commentary with a provocative title–The toxic truth about sugar—and an even more provocative subtitle—Added sweeteners pose dangers to health that justify controlling them like alcohol.

The authors, Robert Lustig, Laura Schmidt and Claire Brindis, are researchers at the University of California medical center in San Francisco (UCSF).

They argue that although tobacco, alcohol and diet are critically important behavioral risk factors in chronic disease, only two of them—tobacco and alcohol—are regulated by governments to protect public health.

Now, they say, it’s time to regulate sugar. By sugar, they mean sugars plural—sucrose as well as high fructose corn syrup (HFCS). Both are about half fructose.

Their rationale?

  • Consumption of sugars has tripled over the last 50 years.
  • Many people consume as much as 500 calories a day from sugars (average per capita availability in the U.S. is about 400 calories a day)
  • High intake of fructose-containing sugars induce metabolic syndrome (high blood pressure, insulin resistance), diabetes, and liver damage.
  • Sugars have the potential for abuse.
  • Sugars have negative effects on society (mediated via obesity).
  • Too much of a good thing can be toxic.

Therefore, they argue, societies should intervene and consider the kinds of policies that have proven effective for control of tobacco and alcohol:

  • Taxes
  • Distribution controls
  • Age limits
  • Bans from schools
  • Licensing requirements
  • Zoning ordinances
  • Bans on TV commercials
  • Labeling added sugars
  • Removal of fructose from GRAS status

In a statement that greatly underestimates the situation, they say:

We recognize that societal interven­tion to reduce the supply and demand for sugar faces an uphill political battle against a powerful sugar lobby, and will require active engagement from all stakeholders.

But, they conclude:

These simple measures—which have all been on the battleground of American politics—are now taken for granted as essential tools for our public health and well-being. It’s time to turn our attention to sugar.

What is one to make of this? Sugar is a delight, nobody is worried about the fructose in fruit or carrots, and diets can be plenty healthy with a little sugar sprinkled here and there.

The issue is quantity. Sugars are not a problem, or not nearly as much of a problem, for people who balance calorie intake with expenditure.

Scientists can argue endlessly about whether obesity is a cause or an effect of metabolic dysfunction, but most people would be healthier if they ate less sugar.

The bottom line? As Corinna Hawkes, the author of numerous reports on worldwide food marketing, wrote me this morning, “there are plenty of reasons for people to consume less sugar without having to worry about whether it’s toxic or not!”
