Let’s start simple then get to the all important nuance.
LA public schools revamped their school lunch program this year to provide healthier food to make healthier kids. Hey, If You Can’t Count It, You Can’t Change It, so what’s the Count?
The new menu, introduced this fall, was hailed as a revolutionary step by the nation’s second-largest school district to combat the growing epidemic of youth obesity, diabetes and other health problems. It was the latest healthful food initiative by the district, which banned sodas on campus in 2004, nixed the sale of junk food during the school day and called for more produce and less salt and fat to be served. This year, L.A. Unified, which serves 650,000 meals daily, has received awards for improving its school lunches, including one last week from the U.S. Department of Agriculture and another from the Physicians Committee for Responsible Medicine.
Hail! Expert Acclaim! Awards!
Any other Counts?
But Barrett said the debut was a “disaster.” Participation plunged by more than 13%, he said. About two-fifths of the loss was tied to 99 schools that temporarily resumed requiring lunch tickets; typically, a drop-off is expected when this occurs. In the last month or so, the overall program has begun to recover; participation is down by about 5% or 6%, Barrett said.
Barrett is Dennis Barrett, L.A. Unified’s food services director. By his own Count student participation dropped 13% immediately, a Small Windowpane effect, but has recovered to only a 5% drop. In other words, a program that is supposed to help people has instead lost people from program participation. Sure, all those drop outs are no longer buying bad food, at least from the school. They are getting it somewhere else.
So, things are not getting better. What to do?
Acknowledging the complaints, L.A. Unified’s food services director, Dennis Barrett, announced this month that the menu would be revised. Hamburgers will be offered daily. Some of the more exotic dishes are out, including the beef jambalaya, vegetable curry, pad Thai, lentil and brown rice cutlets, and quinoa and black-eyed pea salads. And the Caribbean meatball sauce will be changed to the more familiar teriyaki flavor. The district is even bringing back pizza — albeit with a whole wheat crust, low-fat cheese and low-sodium sauce, according to food services deputy director David Binkle.
So, let’s add bad food to the menu and then when participation rates get back to normal or perhaps even increase, let’s declare victory, throw a parade, and go home, like we did in Iraq . . . except for the parade . . . and the declaration . . . so, just go home!
Nuance time.
Unified has virtually eliminated canned and frozen fruits and vegetables, boosting spending on fresh produce from $2 million in 2006 to $20 million in 2010.
So, we drop the bad food, spend 10 times as much money on good food, get a 5% drop in participation, then add bad food like we had before. Spend a bazillion dollars on something most people don’t use and provokes other people to quit, then keep spending a bazillion while going back to the Old Thing? Thus, the detail shows even dumber persuasion effects. More cost for less effect!
And, where’s the evidence that this will make a large, practical, and beneficial impact on kids’ health? Hey, consider this meta-analysis on the mortality benefits of vegetarian diet.
We combined data from 5 prospective studies to compare the death rates from common diseases of vegetarians with those of nonvegetarians with similar lifestyles. Data for 76172 men and women were available. Vegetarians were those who did not eat any meat or fish (n = 27808). Mortality from ischemic heart disease was 24% lower in vegetarians than in nonvegetarians. There were no significant differences between vegetarians and nonvegetarians in mortality from cerebrovascular disease, stomach cancer, colorectal cancer, lung cancer, breast cancer, prostate cancer, or all other causes combined.
If you’re just joining us a Small Effect would be 50%, so, gee, 24% is half of Small, about a 48/52 Windowpane. For everyone always eating broccoli their whole lives we could increase life span about 1-2 years. Maybe. Remember these are Observational Studies with no randomization or control and a ton of self selection bias in the convenience samples. A half of a Small Effect under these conditions is not a ringing endorsement of the Research Hypothesis.
So, in this great field persuasion project, LA is spending more money for fewer participants while returning to old ways and likely producing no detectable mortality effect. By their own numbers!

P.P.S. Persuasion Bonus! Celebrity chef Jamie Oliver is mixed into this LA persuasion farce. We’ve seen Jamie’s play before – he sells his cookbooks and restaurants as solutions to the obesity epidemic . . . with a straight face. Oliver let the LA Food Services people draw a large crowd, then he showed up, and started blowing raspberries at them. It’s a pure Reception play, Stepping Into Somebody Else’s Spotlight.
