This year's Annual Review of Nutrition is out and full of really great reads.

My contribution details the broad history of nutritional guidance in America & covers the forces (science/politics/culture) that have driven the evolution of nutrition guidance.

A good insider view of a dysfunctional FDA, helping to explain why Makary said leucovorin would treat 100Ks of kids w autism, meanwhile they pursued an indication for the rare disease of CFD.

FDA is choosing political wins at the expense of false hope for millions of families/ individuals w autism.

Employees inside the FDA and outside experts said they were worried the U.S. is headed toward a new era of drug regulation: one where political decisions lead, and evidence follows

Current and former FDA staff said the level of involvement of political officials in nitty-gritty regulatory matters is unprecedented.

The entire team that oversees NHANES mobile examination operations was RIFed. NHANES (National Health and Nutrition Examination Survey) is our national program that sends mobile clinics across America to collect blood, urine, and health data from thousands of Americans each year. Unlike some other CDC cuts that have been reversed, this one hasn't - at least not yet. And there's no alternative plan in place.Without this team, the NHANES survey is unlikely to be able to continue. They don't just do planning for the next cycle (which their name might suggest) - they primarily conduct the day-to-day operations that keep the mobile units running.Why does this matter? NHANES is our only nationally representative source for:➡️Dietary intake data➡️Biomarkers of environmental toxins (pesticides, heavy metals, PFAS in blood/urine)➡️Population-level cardiovascular risk factors measured through actual blood work➡️Nutritional biomarkers (not self-reported)The data from NHANES is key for monitoring, surveillance, and discovery. It's how we know about diet quality & nutritional status, rates of obesity, and trends in blood glucose and cholesterol control. It's also how we monitor the prevalence of established and emerging toxins - everything from lead to PFAS. Continual collection of data is essential for tracking progress on public health goals, where we are falling short, and identifying the next link between exposures and health. Experts have readily called for an INVESTMENT in NHANES - so that we can sample broader populations, measure novel biomarkers & capture more environmental exposures. These cuts threaten the continuity of this key engine of public health, and we should all be concerned, regardless of party or politics.

NHANES has been facing funding challenges and needs an infusion of cash to be modernized, not cut. These samples are a key dataset for the field of medicine, nutrition, metabolism, endocrinology, aging, etc.
So much innovation that could be brought to Nhanes!

Everyone across biomedicine should be very loud about this so this team's RIF status gets reversed. Nhanes has been key for tracking obesity & diabetes rates, identifying high blood lead levels in kids in the 70s, tracking progress on cholesterol lowering, guiding nutrient fortification programs etc

MMWR stole the show in the first round of headlines about CDC cuts but in the chaos, many missed that the NHANES mobile team remains RIF'd. This is the backbone of this key survey that contains some of the only representative anthropometric, biochemical, clinical and dietary data on the country.

STAT @statnews.com · 14h

Protecting the nation’s public health demands data, whether it be new measles cases, a surge in ER visits, or shifting patterns in obesity. The most recent job cuts at the CDC threaten the mostly unseen foundation of that research enterprise.

CDC team running top survey on health and nutrition is laid off

NHANES has collected data on eating patterns, diabetes and other common diseases for decades. The CDC team that runs it has been fired.

This moment -- when we have a failing traditional healthcare system + increasing acceptance of low evidence, hyperbolic 'food is medicine'/lifestyle/functional medicine' + a government eager to co-opt/endorse wellness slop -- is particularly scary for folks who care abt evidence-based nutrition

Nancy Mace on Bill Maher telling pregnant women to take Ibuprofen instead of Tylenol is so emblematic of everything wrong with this administrations approach to health.

But Nope, just a silver bullet political win that's causing chaos over access to leucovorin & parents left to plan restrictive diets alone while getting mixed information online

Kevin C Klatt, PhD, RD @kcklatt.bsky.social · 17d

The admin didn't have to do any of this. This could've been a funding announcement for a well powered multi center trial of leucovorin that considered key covariates. They could've pushed Congress behind the scenes to expand access to dietitian coverage for individuals with autism.

Kevin C Klatt, PhD, RD @kcklatt.bsky.social · 17d

Sad for parents desperate for help & being heard online now paying for genetic tests, designer vitamins, & bending over backwards to feed restrictive diets they've been told are toxic. Sad for the kids w autism being fed restrictive diets, some of which will inevitably be imbalanced & cause harm.

The leucovorin story is already blending with existing misinformation online about folic acid and MTHFR genotypes to create a new generation of medicalized claims without much evidence.

FYI Jenny McCarthy is now out here promoting the Tylenol - Autism link citing its impact on glutathione and promoting IV infusions of glutathione.

Kevin C Klatt, PhD, RD @kcklatt.bsky.social · 18d

and for folks who don't follow this, it is nearly all naturopaths, chiropractors and 'integrative' medicine folks who are pushing the glutathione rationale b/c they get to sell N-acetylcysteine & Vitamin C supplements (of which there are many poorly contextualized papers out there also hyping).

So many papers are clearly written to sex up impact and claim translatability, at the expense of accuracy - that's a gift to pseudoscience. We need to be training the next generation of scientists to be honest and media literate.

Kevin C Klatt, PhD, RD @kcklatt.bsky.social · 18d

Every basic scientist & PhD program director should be watching how cell culture and rodent models of Tylenol exposure are being used by motivated parties (e.g. it depletes your glutathione! Science proves it PMID...) to sell a narrative and sow confusion right now.

How will this help ensure Medicaid coverage for general ASD?

Not just a flub of the white house comms - GSK is confirming the new indication for CFD and even highlights that it's rare

Kevin C Klatt, PhD, RD @kcklatt.bsky.social · 22d

It's very bizarre that the admin pursued a leucovorin indication for children with cerebral folate deficiency and autism symptoms, not for general autism. CFD is rare and the diagnosis is confirmed by measuring folate levels in cerebrospinal fluid, which most general cases of autism won't have.
