What’s up with food and nutrition in 2010?

My San Francisco Chronicle column, now appearing in print on the first Sunday of the month, is also online.

Its title:  “Hot food issues ready to boil over this year.”

Q: What do you think will happen with food and nutrition in 2010?

A: I wish I could read the leaves while I drink tea, but the best I can do is tell you which issues I’m going to be watching closely this year.

Hunter Public Relations recently asked 1,000 Americans which food-related issues they thought were most important in 2009. The top three? Food safety, hunger and food prices. For the decade, the winner was childhood obesity.

I have my own top 10 list of hot-button issues for 2010, and here they are:

  • Hunger: More than 35 million Americans get benefits to which they are entitled under the Supplemental Nutrition Assistance Program (formerly, food stamps). The economy may be improving, but not quickly enough for millions who have lost jobs, health care and housing. Will Congress do anything this year to strengthen the safety net for the poor? It needs to.
  • Childhood obesity: Rates of childhood obesity may have stabilized, but we all want to figure out how to prevent kids from gaining so much weight that they develop adult chronic diseases. I expect to see more efforts to improve school food and make neighborhoods more conducive to walking to school, riding bikes and playing outside.
  • Food safety regulation: Congress is sitting on a bill to give the Food and Drug Administration some real authority for food safety. The bill does not do what is most needed – establish a single food-safety agency – but is a reasonable step in the right direction. Let’s hope Congress gets to it soon.
  • Food advertising and labels: The long-dormant FDA and Federal Trade Commission are getting busy at last. In the wake of the Smart Choices fiasco, the FDA is working to make package labels less misleading and easier to understand. The agencies have proposed nutrition standards for products marketed to children. These voluntary standards fall far short of my preference – an outright ban on marketing junk foods to kids – but puts food companies on notice that their products are under scrutiny. The FDA is also working on designs for front-of-package labels. I’m hoping it chooses a “traffic-light” system that marks foods with a green (any time), yellow (sometimes) or red (hardly ever) dot. Expect plenty of opposition from the makers of red-dotted products.
  • Meat: The meat industry has been under fire for raising food animals under inhumane conditions, using unnecessary hormones and antibiotics, mistreating immigrant labor, and polluting soil and water. Now it is also under fire for contributing to climate change. Recent films like “Food, Inc.” and “Fresh” and books such as Jonathan Safran Foer’s “Eating Animals” are encouraging people to become vegetarians or to eat less meat to promote the health of people and the planet. I’ll bet the meat industry pushes back hard on this one.
  • Sustainable agriculture: The back-to-the land movement has loads of people buying local food, choosing foods produced under more sustainable conditions and growing their own food. The number of small farms in America increased last year for the first time in a century. Seed companies cannot keep up with the demand. It will be fun to follow what happens with this trend.
  • Genetically modified (GM) foods: My book, “Safe Food,” comes out in a new edition this year, so I am paying especially close attention to debates about GM foods. The FDA’s 1994 decision to prohibit labeling of GM foods continues to haunt the food biotechnology industry. By now, nearly all American soybeans and sugar beets (95 percent) are GM, as is most corn (60 percent). But when the U.S. Department of Agriculture approved GM sugar beets in 2005, it neglected to perform the required environmental impact assessment. On that basis, environmental groups want to ban further planting of GM sugar beets. The dispute is now in the courts.
  • Chemical contaminants: The FDA has yet to release its report on the safety of bisphenol A, the plastic chemical that acts as an endocrine disrupter. Shouldn’t it be banned? The bottling industry says no. Watch for fierce arguments over this one.
  • Salt: Nutrition standards allow 480 mg sodium (the equivalent of more than 1 gram of salt) per serving. A half cup of canned soup provides that much. A whole cup gives you 4 grams and the whole can gives you 8 grams – much more than anyone needs. Nearly 80 percent of salt in American diets comes from processed and restaurant foods. Companies are under pressure to cut down on salt. Will they? Only if they have to.
  • Dietary advice: The new edition of Dietary Guidelines for Americans, which the government publishes every five years, is due this year. What will it say? I can’t wait to find out.

Those are the issues I am tracking these days. My one crystal-ball prediction? We will be hearing a lot more about them this year.

Happy new year!

Hormones in the food supply

The Institute for Agriculture and Trade Policy (IATP) in Minneapolis has a new report out that summarizes research on hormones in the food supply, of which there are many: arsenic growth promoters, recombinant bovine growth hormone, synthetic hormones in packaging (plasticizers, bisphenol A), and industrial contaminants (dioxins, PCBs, etc).  Never has the statement “more research needed” made more sense.  Plenty of uncertainties still remain about how much, if any, harm is caused by these substances, but while waiting for that research, IATP advises: avoid.  How?  Eat low-fat meat and dairy foods (these chemicals are stored in fatty tissues) and organics (these should be free of hormone-like substances or have much less), don’t use plastic containers made with bisphenol A, and get busy on changing policy!

Regulation of bottled water: oops

There is so much wrong with bottled water that it’s hard to know where to begin (read Elizabeth Royte’s Bottlemania, for starters).  But let’s start with the fact that bottled water is the most brilliantly marketed product ever invented.  The companies get it practically free out of a tap and charge you a dollar or more – sometimes a lot more – for a quart or less).  The plastic bottles pollute the environment.  Worst of all, drinking bottled water makes people less apt to be vigilant about protecting public water supplies.

And it isn’t even regulated very well, or so says a report from the Government Accountability Office.  The title says it all: “Bottled water: FDA safety and consumer protections are often less stringent than comparable EPA protections for tap water.”  The report was released in time for congressional hearings on the topic.   Reporters had a lot of fun with the self-interested statements of industry people who testified.

None of this gets into the additional question of bisphenol A and other endocrine disrupters in plastic bottles that are sometimes used for water.  The Canadians are now saying that bisphenol A is safe at amounts commonly used, and so is a California expert committee.  The American Chemistry Council is pleased with these decisions.

Where does that leave us?  Defend tap water!  As for endocrine disrupters, stay tuned but why use bisphenol A when other alternatives are so readily available.

July 24 update: The International Bottled Water Association is suing a maker of steel water bottles for false advertising.  The bottle maker’s ads apparently suggested that plastic water bottles leak synthetic estrogens.   Bisphenol A must be causing serious problems for the bottled water industry, along with all those pesky enviromental concerns.

Do endocrine disrupters cause asthma and obesity?

According to press reports, investigators from a Mt. Sinai School of Medicine project funded by the Environmental Protection Agency (EPA), “Growing Up Healthy in East Harlem,” find higher levels of endocrine disrupters, mostly phthlates and bisphenol A, among obese girls (age six to eight) in East Harlem, as compared to girls who are not obese.   The actual research does not appear to be published yet – I can’t find it on the Epidemiology website – but the EPA’s site provides the latest report on the project.

Endocrine disrupters are widely used in food and beverage packaging materials, as well as things such as cosmetics, shampoos, lubricants, and paint. As I explained in earlier posts, federal agencies have been taking a hard look at such substances, particularly bisphenol A.  Their interim conclusion: such chemicals pose no harm at current levels of intake.

While waiting for more research or regulatory action, a group called As You Sow has asked food companies what they are doing about bisphenol A.  Its report, Seeking Safer Packaging, concludes that the companies it surveyed generally aren’t doing nearly enough.  A few companies – notably Hain Celestial, Heinz, and Nestle (no relation) do have plans to phase out these chemicals eventually.

Why isn’t there more research on endocrine disrupter chemicals?  Without it, we have only two choices: precaution or do nothing and see what happens.  In this instance, it looks like the evidence favors precaution.  Glass bottles, everybody!

Those worrying plastic water bottles: Consumer Reports weighs in

ConsumerReports.com has an especially understandable description of the plastic bottle situation. If the recycling number is 7, the plastic could be polycarbonate and leaching bisphenol A endocrine disrupters. It says recycling numbers 1, 2, or 5 are better bets. The Environmental Working Group says bisphenol A is the “signature compound in the fight for reform of the nation’s toxic chemicals laws. It contaminates nearly all Americans, it causes toxic effects at very low doses…yet the EPA has only the most clumsy and convoluted authority to control its use and reduce exposure to populations at risk.”

Fiji Water an eco-choice? And what’s with plastic water bottles?

Thanks to Hugh Joseph for forwarding this Brandweek article about Fiji water with a subject line saying, “You could never make this up.” Fiji Water, it seems, has a new $10 million ad “carbon negative, globally positive” campaign to explain its carbon neutrality. Hmmm. The last I heard, Fiji was about 8,000 food miles away and plastic bottles were causing all kinds of environmental problems.

And now it seems that plastic bottles are also causing health problems, particularly from leaching of the endocrine disrupter, bisphenol A. Canada is all set to ban this chemical in general and has just banned it from baby bottles. The FDA is under pressure to do the same or at least set limits for it. And Nalgene says it won’t use it anymore.

Maybe Fiji Water bottles don’t use polycarbonate plastics (with bisphenol A) but it looks like any bottled water needs some re-thinking, no?
