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!

Chocolate milk redux: Nutrifluff vs. Policy

First, the “Nutrifluff,” my term for research with results that are intriguing but of unknown clinical significance.  I thank everyone who sent me links to the New York Times account of the new study linking chocolate milk to reduced inflammation.  It quotes the lead author:  “Since atherosclerosis is a low-grade inflammatory disease of the arteries, regular cocoa intake seems to prevent or reduce [it].”   But the giveaway is the next magic words that cover all bases: “more studies needed.”

The study suggests – but in no way proves – that drinking chocolate milk reduces the risk of coronary artery disease.  Inflammation is an intermediate marker of suggestive but unconfirmed clinical implications.  More research is needed, indeed.

Next, policy.  Recall the fuss over chocolate milk (see previous post on the topic)?   Marlene Schwartz of the Rudd Center at Yale has posted an explanation of her views on the matter.

The “chocolate milk controversy” story this week is not about nutrition; it’s about marketing…They explain that “more than half of all flavored milk is sold in schools,” and “the importance of flavored milk goes beyond the school market because it is a key growth area for milk processors.”

They are trying to sell their product. There is nothing wrong with that as long as their marketing efforts are not misleading. Chocolate milk is not the nutritional equivalent of regular milk. It is significantly higher in calories, sugar (often high fructose corn syrup), sodium, and usually contains artificial colors and flavors.

In the promotional video on YouTube, expert dieticians acknowledged that chocolate milk has about 60 more calories per serving than regular milk, but then quickly added that “in the grand scheme of things, that’s nothing compared to the amount of nutrients they are going to be getting.”

That sounded really familiar.

“In the grand scheme of things, these calories don’t count” is exactly what we heard from David Mackay, the CEO of Kellogg in his defense of marketing his company’s high-sugar cereals: “Twelve grams of sugar is 50 calories. A presweetened cereal as part of a regular diet for kids is not a bad thing.”

50 calories here, 60 calories there, and pretty soon we are talking about real weight gain.

Our research has found that children will eat low-sugar cereals and drink white milk when these are the foods that are served. We also found that most children will also eat a piece of fruit if you prompt them to take it. School cafeterias are the perfect place to reinforce the nutrition lessons that begin at home and promote nutrient-dense foods.

If chocolate milk were the only treat children were exposed to in schools, it would not be nearly as much of a problem.  But it is not.  In many schools, kids are offered sweet treats all day long (birthday celebrations, rewards from teachers, etc) or exposed to those readily available from vending machines.  So sweet foods have become the norm.  Norms are hard to change, but let’s at least not make them worse.

Labeling GM foods: if the U.K. can do it, we can too!

You will recall that the FDA’s 1994 stance on labeling of genetically modified (GM) foods was that labeling foods as GM or non-GM would be misleading  because the foods are no different.  Despite overwhelming evidence that the public wants to know whether foods are GM or not, GM foods do not have to be labeled.  Worse, those that are labeled non-GM have to include a disclaimer that this makes no difference (I explain how all this happened in Safe Food).

At present, there is no way to know whether GM foods that have been approved by FDA (such as potatoes, tomatoes, squash, papayas) are actually in the produce section of supermarkets.  When I was writing What to Eat, I paid to have some papayas tested.  Most were not GM.  But you have no way of knowing that.

The GM industry (translation: Monsanto) has opposed labeling from the very beginning, no doubt because of fears that people will reject GM foods.  The makers of processed foods object to labeling because practically everything they make contains GM ingredients: about 90% of the soybeans and 50% of the corn grown in America is GM.  Ingredients made from these foods – corn and soy oils, proteins, and sweeteners – are widely used in processed foods.

The Europeans are faced with the same problem but insist on labeling GM.  Guess what?  No problem.  Hershey’s Reese’s NutRageous candy bars in the U.K. disclose the GM ingredients in exactly the way our products disclose allergens: “Contains: Peanuts, Genetically Modified Sugar, Soya and Corn.”

Here’s the label (borrowed from Mike Grenville at flickr.com/photos):

Hershey is an American company.  If labeling in the U.K. is this simple, we ought to be able to do this here, no?  Here’s a chance for the FDA to fix an old mistake and give consumers a real choice.

How could E. coli O157:H7 get into cookie dough?

Thanks to Bill Marler for discussing this question on his blog this morning and for suggesting starting with the ingredient list.  As a typical example, here is the ingredient list for Nestlé’s Chocolate Chunk cookie dough (others can be found at this site):

INGREDIENTS: BLEACHED ENRICHED FLOUR (WHEAT FLOUR, NIACIN, REDUCED IRON, THIAMIN MONONITRATE, RIBOFLAVIN, FOLIC ACID), SUGAR, NESTLE SEMI-SWEET CHOCOLATE CHUNKS (SEMI-SWEET CHOCOLATE [SUGAR, CHOCOLATE, COCOA BUTTER, MILKFAT, SOY LECITHIN, VANILLIN – AN ARTIFICIAL FLAVOR, NATURAL FLAVOR]), MARGARINE (PALM OIL, WATER, SUNFLOWER OIL, HYDROGENATED COTTONSEED OIL, SALT, VEGETABLE MONO- AND DIGLYCERIDES, SOY LECITHIN, SODIUM BENZOATE, CITRIC ACID, NATURAL AND ARTIFICIAL FLAVOR, BETA CAROTENE COLOR, VITAMIN A PALMITATE ADDED), WATER, CORN SYRUP SOLIDS, MOLASSES, EGGS, EGG YOLKS, BAKING SODA, SALT, CORNSTARCH, SODIUM ALUMINUM PHOSPHATE, VANILLA EXTRACT, VANILLIN – AN ARTIFICIAL FLAVOR

MADE ON EQUIPMENT THAT ALSO PROCESSES PEANUTS/NUTS

CONTAINS: MILK, EGG, SOY, WHEAT INGREDIENTS

For starters, we don’t really know yet whether raw cookie dough is the source of this E. coli outbreak.  It could be something else, and Nestlé will have recalled 300,000 cases purely out of precaution.  The most likely source of bacterial contamination is eggs, but eggs typically carry Salmonella, not E. coli O157:H7.   And besides, the eggs in raw cookie dough are undoubtedly pasteurized, which ought to kill any bacteria that happen to be present.

The usual source of this toxic form of E. coli is cow manure.  Cows that carry this bug do not necessarily become ill, but they excrete it. Recall the spinach E. coli outbreak in 2006?  The spinach field was one mile away from a cattle crossing over a stream.  California investigators identified the particular strain of E. coli that caused the problem in cattle, cattle feces, and water at the cattle crossing, but did not found it in the field.

All they could do is speculate. Their leading hypotheses were runoff, a change in the water table, and (my favorite) wild boar.  Unfortunately for this last theory, when they surveyed wild boar for E. coli O157:H7, they found fewer than 0.5% to carry it.  So how E. coli got into the spinach remains a mystery.

As for the cookie dough, I’m guessing that everyone involved is having a busy weekend testing the ingredients, the packing plants, and everything else they can think of.  Let’s hope they find the source right away.

HFCS-free sales booming

Thanks to Phil Lempert, the Supermarket Guru, for alerting me to the current HFCS-free sales boom.  HFCS, of course, is High Fructose Corn Syrup, the liquid sweetener made from corn (see previous posts).  Food marketers have gotten the message that many people consider HFCS to be the new trans fat, even though it is not much different biologically from common table sugar (sucrose).

HFCS is replaced easily by sucrose, which used to be much more expensive.  Now, because of the use of corn for ethanol, sucrose is only slightly more expensive than HFCS.

Click on the Table to see the overall 13% growth in sales over the last year, with products like HFCS-free milk drinks, juices, salad dressings, and teas registering 1,500% to 16,000% increases.  Like “trans fat-free,” the term “HFCS-free”  is a calorie distractor.  It too will make you forget about the calories.

The irony is that white table sugar – formerly a leading target of “eat less” messages – suddenly has a health aura.  Marketers have wasted no time moving in to use that aura to sell the same old products.

The latest from Red Bull: Cocaine!

According to Time online, advertising for the sports drink Red Bull Cola made officials in Germany so suspicious that they did a little testing.  Ach du himmel!  Traces of cocaine.  No wonder guys like it so much.

Here is the ingredient list: Water, Sugar, Carbon Dioxide, Caramel Color, Natural Flavors from Plant Extracts (Galangal, Vanilla, Mustard Seed, Lime, Kola Nut, Cacao, Licorice, Cinnamon, Lemon, Ginger, Cocoa Leaf, Orange, Corn Mint, Pine, Cardamom, Mace, Clove), Lemon Juice Concentrate, Caffeine from Coffee Beans.  With these, you get 130 calories, virtually all from sugar, and some unstated amount of caffeine – along with some other no longer quite so secret ingredients, apparently.

Yum.

Update June 5: European regulatory authorities think this is a non-issue and plan no action.

HFCS is the new trans fat?

Will the confusion about sugars never end?  A recent study reconfirms the metabolic problems caused by too much fructose, but public opinion continues to blame High Fructose Corn Sweeteners (HFCS) as the new dietary evil.   HFCS isn’t really high in fructose.  It has about the same amount of fructose as common table sugar.   Both are about half fructose and half glucose, and both cause metabolic problems when you eat too much of them.  So go easy on the sugars!

Here’s what the New York Times has to say about the study.

Sales of HFCS-free foods zoom up

The bad press about high fructose corn syrup (HFCS) is having an effect.  According to figures assembled by Phil Lempert, the Supermarket Guru, sales of products bearing “HFCS-Free” labels almost reached a billion dollars last year.  Fruit drinks are the biggest HFCS-free category, but HFCS-free yogurts, vegetable juices, and breads are the fastest growing. Lempert doesn’t say what companies are using instead of HFCS.  If it’s sucrose, it won’t be much of an improvement.  But no wonder the Corn Refiners think they need a hefty public relations campaign.

March 21 update: This trend is a front-page story in the New York Times.
