In Defense of Food
Page 15
But given our current state of confusion and given the thousands of products calling themselves food, this is more easily said than done. So consider these related rules of thumb. Each proposes a different sort of map to the contemporary food landscape, but all should take you to more or less the same place.
DON’T EAT ANYTHING YOUR GREAT GRANDMOTHER WOULDN’T RECOGNIZE AS FOOD. Why your great grandmother? Because at this point your mother and possibly even your grandmother is as confused as the rest of us; to be safe we need to go back at least a couple generations, to a time before the advent of most modern foods. So depending on your age (and your grandmother), you may need to go back to your great-or even great-great grandmother. Some nutritionists recommend going back even further. John Yudkin, a British nutritionist whose early alarms about the dangers of refined carbohydrates were overlooked in the 1960s and 1970s, once advised, “Just don’t eat anything your Neolithic ancestors wouldn’t have recognized and you’ll be ok.”
What would shopping this way mean in the supermarket? Well, imagine your great grandmother at your side as you roll down the aisles. You’re standing together in front of the dairy case. She picks up a package of Go-Gurt Portable Yogurt tubes-and has no idea what this could possibly be. Is it a food or a toothpaste? And how, exactly, do you introduce it into your body? You could tell her it’s just yogurt in a squirtable form, yet if she read the ingredients label she would have every reason to doubt that that was in fact the case. Sure, there’s some yogurt in there, but there are also a dozen other things that aren’t remotely yogurtlike, ingredients she would probably fail to recognize as foods of any kind, including high-fructose corn syrup, modified corn starch, kosher gelatin, carrageenan, tri-calcium phosphate, natural and artificial flavors, vitamins, and so forth. (And there’s a whole other list of ingredients for the “berry bubblegum bash” flavoring, containing everything but berries or bubblegum.) How did yogurt, which in your great grandmother’s day consisted simply of milk inoculated with a bacterial culture, ever get to be so complicated? Is a product like Go-Gurt Portable Yogurt still a whole food? A food of any kind? Or is it just a food product?
There are in fact hundreds of foodish products in the supermarket that your ancestors simply wouldn’t recognize as food: breakfast cereal bars transected by bright white veins representing, but in reality having nothing to do with, milk; “protein waters” and “nondairy creamer”; cheeselike foodstuffs equally innocent of any bovine contribution; cakelike cylinders (with creamlike fillings) called Twinkies that never grow stale. Don’t eat anything incapable of rotting is another personal policy you might consider adopting.
There are many reasons to avoid eating such complicated food products beyond the various chemical additives and corn and soy derivatives they contain. One of the problems with the products of food science is that, as Joan Gussow has pointed out, they lie to your body; their artificial colors and flavors and synthetic sweeteners and novel fats confound the senses we rely on to assess new foods and prepare our bodies to deal with them. Foods that lie leave us with little choice but to eat by the numbers, consulting labels rather than our senses.
It’s true that foods have long been processed in order to preserve them, as when we pickle or ferment or smoke, but industrial processing aims to do much more than extend shelf life. Today foods are processed in ways specifically designed to sell us more food by pushing our evolutionary buttons-our inborn preferences for sweetness and fat and salt. These qualities are difficult to find in nature but cheap and easy for the food scientist to deploy, with the result that processing induces us to consume much more of these ecological rarities than is good for us. “Tastes great, less filling!” could be the motto for most processed foods, which are far more energy dense than most whole foods: They contain much less water, fiber, and micronutrients, and generally much more sugar and fat, making them at the same time, to coin a marketing slogan, “More fattening, less nutritious!”
The great grandma rule will help keep many of these products out of your cart. But not all of them. Because thanks to the FDA’s willingness, post-1973, to let food makers freely alter the identity of “traditional foods that everyone knows” without having to call them imitations, your great grandmother could easily be fooled into thinking that that loaf of bread or wedge of cheese is in fact a loaf of bread or a wedge of cheese. This is why we need a slightly more detailed personal policy to capture these imitation foods; to wit:
AVOID FOOD PRODUCTS CONTAINING INGREDIENTS THAT ARE A) UNFAMILIAR, B) UNPRONOUNCEABLE, C) MORE THAN FIVE IN NUMBER, OR THAT INCLUDE D) HIGH-FRUCTOSE CORN SYRUP. None of these characteristics, not even the last one, is necessarily harmful in and of itself, but all of them are reliable markers for foods that have been highly processed to the point where they may no longer be what they purport to be. They have crossed over from foods to food products.
Consider a loaf of bread, one of the “traditional foods that everyone knows” specifically singled out for protection in the 1938 imitation rule. As your grandmother could tell you, bread is traditionally made using a remarkably small number of familiar ingredients: flour, yeast, water, and a pinch of salt will do it. But industrial bread-even industrial whole-grain bread-has become a far more complicated product of modern food science (not to mention commerce and hope). Here’s the complete ingredients list for Sara Lee’s Soft & Smooth Whole Grain White Bread. (Wait a minute-isn’t “Whole Grain White Bread” a contradiction in terms? Evidently not any more.)
Enriched bleached flour [wheat flour, malted barley flour, niacin, iron, thiamin mononitrate (vitamin B1), riboflavin (vitamin B2), folic acid], water, whole grains [whole wheat flour, brown rice flour (rice flour, rice bran)], high fructose corn syrup [hello!], whey, wheat gluten, yeast, cellulose. Contains 2% or less of each of the following: honey, calcium sulfate, vegetable oil (soybean and/or cottonseed oils), salt, butter (cream, salt), dough conditioners (may contain one or more of the following: mono-and diglycerides, ethoxylated mono-and diglycerides, ascorbic acid, enzymes, azodicarbonamide), guar gum, calcium propionate (preservative), distilled vinegar, yeast nutrients (monocalcium phosphate, calcium sulfate, ammonium sulfate), corn starch, natural flavor, beta-carotene (color), vitamin D3, soy lecithin, soy flour.
There are many things you could say about this intricate loaf of “bread,” but note first that even if it managed to slip by your great grandmother (because it is a loaf
of bread, or at least is called one and strongly resembles one), the product fails every test proposed under rule number two: It’s got unfamiliar ingredients (monoglycerides I’ve heard of before, but ethoxylated monoglycerides?); unpronounceable ingredients (try “azodicarbonamide”); it exceeds the maximum of five ingredients (by roughly thirty-six); and it contains high-fructose corn syrup. Sorry, Sara Lee, but your Soft & Smooth Whole Grain White Bread is not food and if not for the indulgence of the FDA could not even be labeled “bread.”
Sara Lee’s Soft & Smooth Whole Grain White Bread could serve as a monument to the age of nutritionism. It embodies the latest nutritional wisdom from science and government (which in its most recent food pyramid recommends that at least half our consumption of grain come from whole grains) but leavens that wisdom with the commercial recognition that American eaters (and American children in particular) have come to prefer their wheat highly refined-which is to say, cottony soft, snowy white, and exceptionally sweet on the tongue. In its marketing materials, Sara Lee treats this clash of interests as some sort of Gordian knot-it speaks in terms of an ambitious quest to build a “no compromise” loaf-which only the most sophisticated food science could possibly cut.
And so it has, with the invention of whole-grain white bread. Because the small percentage of whole grains in the bread would render it that much less sweet than, say, all-white Wonder Bread-which scarcely waits to be chewed before transforming itself into glucose-the food scientists have added high-fructose corn syrup and honey to to make up the difference; to overcome the problematic heft and toothsomeness of a real whole grain bread, they’ve deployed “dough conditioners,” including guar gum and the aforementioned azodicarbonamide, to simulate the texture of supermarket white bread. By incorporating certain varieties of albino wheat, they’ve managed to maintain that deathly but apparently appealing Wonder Bread pallor.
Who would have thought Wonder Bread would ever become an ideal of aesthetic and gustatory perfection to which bakers would actually aspire-Sara Lee’s Mona Lisa?
Very often food science’s efforts to make traditional foods more nutritious make them much more complicated, but not necessarily any better for you. To make dairy products low fat, it’s not enough to remove the fat. You then have to go to great lengths to preserve the body or creamy texture by working in all kinds of food additives. In the case of low-fat or skim milk, that usually means adding powdered milk. But powdered milk contains oxidized cholesterol, which scientists believe is much worse for your arteries than ordinary cholesterol, so food makers sometimes compensate by adding antioxidants, further complicating what had been a simple one-ingredient whole food. Also, removing the fat makes it that much harder for your body to absorb the fat-soluble vitamins that are one of the reasons to drink milk in the first place.
All this heroic and occasionally counterproductive food science has been undertaken in the name of our health-so that Sara Lee can add to its plastic wrapper the magic words “good source of whole grain” or a food company can ballyhoo the even more magic words “low fat.” Which brings us to a related food policy that may at first sound counterintuitive to a health-conscious eater:
AVOID FOOD PRODUCTS THAT MAKE HEALTH CLAIMS. For a food product to make health claims on its package it must first have a package, so right off the bat it’s more likely to be a processed than a whole food. Generally speaking, it is only the big food companies that have the wherewithal to secure FDA-approved health claims for their products and then trumpet them to the world. Recently, however, some of the tonier fruits and nuts have begun boasting about their health-enhancing properties, and there will surely be more as each crop council scrounges together the money to commission its own scientific study. Because all plants contain antioxidants, all these studies are guaranteed to find something on which to base a health oriented marketing campaign.
But for the most part it is the products of food science that make the boldest health claims, and these are often founded on incomplete and often erroneous science-the dubious fruits of nutritionism. Don’t forget that trans-fat-rich margarine, one of the first industrial foods to claim it was healthier than the traditional food it replaced, turned out to give people heart attacks. Since that debacle, the FDA, under tremendous pressure from industry, has made it only easier for food companies to make increasingly doubtful health claims, such as the one Frito-Lay now puts on some of its chips-that eating them is somehow good for your heart. If you bother to read the health claims closely (as food marketers make sure consumers seldom do), you will find that there is often considerably less to them than meets the eye.
Consider a recent “qualified” health claim approved by the FDA for (don’t laugh) corn oil. (“Qualified” is a whole new category of health claim, introduced in 2002 at the behest of industry.) Corn oil, you may recall, is particularly high in the omega-6 fatty acids we’re already consuming far too many of.
Very limited and preliminary scientific evidence suggests that eating about one tablespoon (16 grams) of corn oil daily may reduce the risk of heart disease due to the unsaturated fat content in corn oil.
The tablespoon is a particularly rich touch, conjuring images of moms administering medicine, or perhaps cod-liver oil, to their children. But what the FDA gives with one hand, it takes away with the other. Here’s the small-print “qualification” of this already notably diffident health claim:
[The] FDA concludes that there is little scientific evidence supporting this claim.
And then to make matters still more perplexing:
To achieve this possible benefit, corn oil is to replace a similar amount of saturated fat and not increase the total number of calories you eat in a day.
This little masterpiece of pseudoscientific bureaucratese was extracted from the FDA by the manufacturer of Mazola corn oil. It would appear that “qualified” is an official FDA euphemism for “all but meaningless.” Though someone might have let the consumer in on this game: The FDA’s own research indicates that consumers have no idea what to make of qualified health claims (how would they?), and its rules allow companies to promote the claims pretty much any way they want-they can use really big type for the claim, for example, and then print the disclaimers in teeny-tiny type. No doubt we can look forward to a qualified health claim for high-fructose corn syrup, a tablespoon of which probably does contribute to your health-as long as it repl
aces a comparable amount of, say, poison in your diet and doesn’t increase the total number of calories you eat in a day.
When corn oil and chips and sugary breakfast cereals can all boast being good for your heart, health claims have become hopelessly corrupt. The American Heart Association currently bestows (for a fee) its heart-healthy seal of approval on Lucky Charms, Cocoa Puffs, and Trix cereals, Yoo-hoo lite chocolate drink, and Healthy Choice’s Premium Caramel Swirl Ice Cream Sandwich-this at a time when scientists are coming to recognize that dietary sugar probably plays a more important role in heart disease than dietary fat. Meanwhile, the genuinely heart-healthy whole foods in the produce section, lacking the financial and political clout of the packaged goods a few aisles over, are mute. But don’t take the silence of the yams as a sign that they have nothing valuable to say about health.
Bogus health claims and food science have made supermarkets particularly treacherous places to shop for real food, which suggests two further rules:
SHOP THE PERIPHERIES OF THE SUPERMARKET AND STAY OUT OF THE MIDDLE. Most supermarkets are laid out the same way: Processed food products dominate the center aisles of the store while the cases of ostensibly fresh food-dairy, produce, meat, and fish-line the walls. If you keep to the edges of the store you’ll be that much more likely to wind up with real food in your shopping cart. The strategy is not foolproof, however, because things like high-fructose corn syrup have slipped into the dairy case under cover of Go-Gurt and such. So consider a more radical strategy:
