Ten percent of the world’s population is now obese, and obesity levels are rising even in countries previously known for food scarcity, says a study designed by the Institute for Health Metrics and Evaluation.

The American Academy of Pediatrics says that far from being a healthy drink, "Fruit juice has no essential role in healthy, balanced diets of children." American children between the ages of 2 and 18 consume almost half their fruit intake in the form of juice, but doctors warn that has to stop.

Slightly more than 63 percent of Americans surveyed by Gallup last year said they have healthy diets. The figure, based on more than 177,000 interviews as part of a Gallup project with Sharecare, was the lowest since the project began in 2008 and was the sixth year in a row of a decline from the peak of 67.7 percent in 2010.

Voters in Santa Fe, New Mexico, decide today whether to adopt a 2-cent-per-ounce tax on sugary beverages — not just on sodas, but on sweetened sports drinks like Gatorade, lemonades and caffeinated energy drinks, among others, says U.S. News & World Report. Artificially sweetened drinks, infant formula, chocolate milk, pure fruit juices, and weight-loss drinks like Ensure would be exempted.

Drinking one to six diet sodas a week doubles the risk for stroke and may also increase the risk for dementia, according to a study of 4,000 people over age 45 in the journal Stroke. The reasons for the link are unknown, says The New York Times.

A long-running study "reports that lowering sodium intake doesn't reduce blood pressure," says the San Diego Tribune. The results are contrary to long-accepted medical advice and suggest that most Americans consume healthy amounts of salt, the most common form of sodium.

A large majority — 85 percent — of the parents polled about food marketing said foodmakers should reduce advertising to induce children to eat unhealthy foods, said the Rudd Center for Food and Obesity. The University of Connecticut center said that since 2012 support increased among parents for "policies to promote healthy eating habits for their children in the media, schools and communities."

The nation’s first soda tax, Berkeley, California’s one-cent-per-ounce levy, hasn’t impacted retail businesses, but it has reduced soda purchases by 9.6 percent, says a new study by the University of North Carolina.

New Mexico has approved the nation's first law to ban “lunch shaming” students who can’t afford school lunches or whose parents fall behind on payments. The Hunger-Free Students’ Bill of Rights, signed by New Mexico Gov. Susana Martinez, applies to all schools, public or private, that accept federal money for students' breakfast or lunch.

Opponents of Philadelphia's 1.5-cent-an-ounce tax on sugary beverages, who lost last year in Common Pleas court, asked the Commonwealth Court to overturn the levy as a form of double taxation, said the Associated Press. In arguments before a seven-judge panel, attorney Chip Becker said the state already imposes a sales tax on soda so the city is barred by law from taxing it too.

Nervous that applying for food stamps will hurt their immigration status or put them at risk of deportation, immigrants are dropping food relief services. “Officials at Manna Food Center in Montgomery County, Md., report that about 20 percent of the 561 families they have helped apply for food stamps, or SNAP benefits, in the past few months have asked that their cases be closed,” says NPR.

The continuing slump in the farm economy and shortcomings in the U.S. farm program make it imperative for Congress to provide additional funding for the 2018 farm bill, said a powerhouse bloc of farm groups. Their appeal to congressional budget and appropriations leaders came two weeks after the House Agriculture Committee asked for more money so it could plug holes in the farm safety net.

Schools across Britain will see an additional 1 billion pounds ($1.2 billion) for sports from a tax on sugary beverages that will be imposed beginning in April 2018, said Phillip Hammond, chancellor of exchequer, in laying out the proposed government budget. The tax was announced last March as step toward better public health through lower rates of obesity, diabetes and tooth decay, said the Independent.

People will eat more healthy food if prices are lowered and consume less unhealthy food and fewer sugary beverages if they cost more, say researchers who performed a meta-analysis of 30 studies on the issue. Co-author Ashkan Afshin said the meta-analysis demonstrated causality: "Our results show how 10 to 50 percent changes in price of foods and beverages at checkout could influence consumers’ purchasing behaviors over a relatively short period of time.”

Domestic production of olive oil, based mostly in California, is six times larger than it was 20 years ago but it amounts to less than 2 percent of the U.S.'s steadily growing consumption, forecast to be more than 400,000 metric tons this year, say USDA analysts. Drought in Europe, the major producer, drove import prices to record highs but they are projected to decline in the year ahead as production recovers.
