Here’s some food news that caught our eye this week:

1. NYC Asks Top Court to Revive Bloomberg’s Big-Soda Ban (Bloomberg News)

The New York City Department of Health has brought a case to the state’s Court of Appeals in an attempt to revive former Mayor Michael Bloomberg’s rule to ban large sodas in the city. Citing the need to curb the growing obesity epidemic, the Department approved the measure in 2012 to restrict the sale of sugary beverages like soda in containers over 16 ounces. A member of the New York State Supreme Court struck down the rule the day before it was supposed to go into effect in March 2013, arguing that the Department was superseding its executive authority and needed legislative approval to move forward. Support from current NYC Mayor Bill de Blasio, who has taken up several of Bloomberg’s public health causes, has brought new energy into the debate. Now, advocates for the soda ban are trying to make the case to the Court of Appeals that the Health Department’s mission to protect public health renders the rule permissible. They face staunch opposition from industry groups like the American Beverage Association, who claim the rule infringes on people’s ability to make their own choices.

2. How to Make Sense of Sugar (The Atlantic)

What’s the deal with agave nectar, anyway? Recent buzz about the high fructose content in the sugar substitute has some prominent figures in the public health arena rescinding their previous endorsements of the product. Dr. Oz and Andrew Weil, once vocal fans of agave, have stopped using it altogether, noting that the syrup distilled from the agave plant is nearly 90 percent fructose (for comparison, table sugar is about 50 percent fructose and high fructose corn syrup is about 55 percent). All sugars have a balance of fructose and glucose, but some research suggests that a higher proportion of fructose can have unique negative effects on liver function and metabolism. While the author of this piece doesn’t argue that we should start taking agave nectar off the shelves, he does argue that those “all natural” claims the product typically bears may not make it any healthier than sugar.

3. Mothers Pressure EPA to Recall Roundup Herbicide (Reuters)

Representatives from the group Moms Across America met with EPA officials last month to pressure the agency to halt the use of Roundup, a widely used herbicide developed by Monsanto. In April 2014, the group found that glyphosate, the primary ingredient in Roundup, is present in women’s breast milk and urine. They argue that glyphosate poses a significant health risk to humans, particularly to women and infants, and that EPA should restrict the use of Roundup when the herbicide comes under review later this year. So far, the EPA has stated that the majority of studies they’ve reviewed–many of which were funded by industry scientists–show no conclusive risk factors associated with glyphosate.

4. Mad Cow Disease Claims Fourth Victim in Texas (Modern Farmer)

The Centers for Disease Control has reported the fourth fatal case in the U.S. of variant Creutzfeld-Jakob Disease (vCJD), a degenerative condition that has been linked to bovine spongiform encephalopathy (BSE), better known as mad cow disease. The victim lived in Texas, though public health officials believe it’s likely that he contracted the disease while abroad as BSE is extremely rare in the U.S. The FDA has issued several feed bans to protect U.S. consumers from BSE, as scientists commonly believe that cows contract the disease by eating feed made from parts of other cows. Global incidents of BSE have also decreased dramatically since the mid-1990s, when rates of BSE among cattle in the United Kingdom hit a peak of 1,000 new cases per week. CDC officials report that the most recent case in the U.S. is not a sign that mad cow disease poses a significant threat to consumers.
