WASHINGTON, D.C. – The new “Let’s Move” director has fired back at a student to complained to Michelle Obama that the program “ruined Taco Tuesday.”

Seven-year-old St. Joan of Arc School student Richard “Trip” Klibert wrote to the first lady explaining what happened at his school after the federal school lunch rules were implemented.

“Thank you for trying to make my school lunch better, but you have ruined Taco Tuesday. Please bring back the old taco shell. I miss them. Also, the pizza is terrible. If you would like to try the new tacos, I will buy you lunch,” the boy wrote, according to the Times-Picayune.

Now, “Let’s Move” program director and senior White House nutrition director Deb Eschmeyer has weighed in, poo-pooing Klibert’s complaint.

Asked about the “whole wheat taco” story, she responded, “I really don’t let that faze me because I have been doing this on the ground for so long,” according to Yahoo Food.

“And a lot of times it’s easier to profile a fight, that’s a sexier story, when actually the food service infrastructure is trying really hard to meet the standards, and 90 percent of the schools have met the standards.”

That is likely Klibert’s point: His school is meeting the standards and he’s suffering the consequences.

Yahoo writer Jeff O’Heir related a personal story – that his wife, a teacher, sees students leave the cafeteria hungry because “the new portion sizes are too small” – and Eschmeyer brushed that off, too.

She even seemingly blamed the Bush administration for the kerfuffle.

“This is the first time the nutrition standards have been updated in 15 years. It was drastic. We were finally matching the national school lunch program with the Institute of Medicine’s recommendations, which, by the way, were made in 2007, prior to this administration.”

Eschmeyer admits the clock is ticking on the Obama administration and they’re doing as much as they can as quickly as they can.

“For me, I think the challenge is, especially now with 21 months left in this administration, what can we move the needle on for the most important issues, in the quickest and most powerful way, that creates a healthier America,” she says.

The administration doesn’t seem too concerned about complaints over portion sizes, caloric content or whether schools are serving meals students are actually willing to eat. It’s just pedal to the metal for “progress.”

“And the other part of it is looking at what we’ve already accomplished and make sure we don’t go backwards. We have to make sure that everything we put so much work into, that everything that has happened in last five years, we continue to make progress and measure our progress. We cannot lose that momentum.”
