Why Can't the Experts Agree on Which Diets Work?

When Howard Helmer retired as the senior national representative for the American Egg Council in 2010, at the age of 72, after 42 years doing what he called “hustling eggs,” it was the end of the era. As a hungry young food writer in the early 1990s, the single best thing that could happen was lunch with Helmer: He had an extravagant expense account and excellent taste in restaurants, and was fabulous company; from his encyclopedic knowledge of Broadway musicals to his status as a two-time Guinness World Record holder (the world’s fastest omelette, in 39 seconds, and the most omelets ever made in 30 minutes: 427, which he admitted were “moist”) no topic was off limits. There was only one thing he wouldn’t discuss: “the cholesterol debacle,” as he called it, that dogged eggs. Helmer was referring to the fact that in the 1980s America’s leading nutritionists cited health studies that warned the country off eggs, associating them with tremendously increased risk of high blood pressure and heart disease. Although the idea had been debunked by the time I encountered Helmer, there were still some stubborn Americans — both clinicians and consumers — clinging to it.
And that’s what happens when doctors and scientists tell us what to eat and then, down the line, change their minds. Meanwhile, the crisis of obesity in America gets bigger, literally. In February, the bestselling nutrition, science, and health author Gary Taubes reported in The New York Times that obesity and its related diseases, especially Type 2 diabetes, cost the U.S. health care system more than $1 billion per day. So if, say, an egg is bad for you or not is detrimental: “It’s not hyperbolic to suggest that the health of the nation may depend on which is the correct answer” to these dilemmas of what to eat, Taubes asserted.
Along with the obesity rate in this country, the suggestions for overcoming it have also ballooned: In 1960, fewer than 13 percent of the American public was obese and fewer than 1,100 articles on the subject had been published; last year, more than 36 percent of the American public could be considered obese, and more than 44,000 articles were published on the topic. So the more and longer we hypothesize, the fatter we get.
While we’re contemplating our collective fatness, we wander the aisles of our local Piggly Wiggly in hopes of figuring out a plan for dinner. These are a few of the trendy dietary choices you have as an American head of household concerned about her or his weight:
You could go Paleo and follow the so-called “cave man” diet based on the eating patterns of our Paleolithic ancestors as popularized by the folks who do Cross Fit and post selfies of pulling tractor tires across gym parking lots. This diet advocates eating lots of lean protein, “alternative fats” like coconut and macadamia nut oil, and all the vegetables you can manage — but no dairy, wheat, or sugar (including the natural kind found in most fruits).
You could go low-fat as the U.S. Department of Agriculture suggests with its carb-heavy food pyramid in a plan that rode a considerable wave of popularity throughout the 1990s and is still touted by groups including the National Heart Lung and Blood Institute. Do this and you'd buy foods like light mayonnaise, diet soda, fat-free yogurt, low-fat microwave popcorn, and skim milk.
You could go vegan and observe an animal-product-free diet (no meat, no dairy). Initially touted by hippies and yogis and now embraced by celebrities from Alec Baldwin to Ozzy Osbourne (we’ll give Ozzy credit even though he barely lasted “more than a week or two”), this diet is big on foods like brown rice, black beans, lentil soup, and veggie burgers topped with vegan tofu-based cheese (no eggs, though).
You could go straight-up low-calorie and buy a full complement of Lean Cuisine entrées (Lean Cuisine is owned by Nestlé, the self-described “World’s Leading Nutrition, Health, and Wellness company”) for three meals a day, including a Canadian bacon English muffin for breakfast (180 calories, 650 milligrams of sodium, 27 grams of carbohydrates), a chicken club panini for lunch (360 calories, 675 milligrams of sodium, 45 grams of carbohydrates), and an enchilada rojo with Mexican-style rice for dinner (310 calories, 670 milligrams of sodium, 46 grams of carbohydrates).
