Nutrition isn't prescriptive - advice will always be a mix of evidence, philosophy, values, culture, economics etc. We already see so much nutr messaging that lacks applicability across cultures, economic status - all too often that same style appeals to nature & harms other areas of public health

Evidence-based health advice is a continuum of which nutrition is just a part of. Nutrition professionals have a responsibility to communicate is ways that are based on the evidence AND don't fuel fires that make communication harder for other areas of public health.

2009-2014 foodie tropes weve see rearing their heads as anti vaccine tropes since COVID
'if you can't pronounce it dont eat it'
'if your grandmother wouldnt recognize it don't put it in your body'

This satfat focus centers noise and being anti-establishment - missing a huge opportunity to double down on refined carbs & the lack of long chain n3 Pufa intakes from fish.

There aren't blockbuster controlled trials with disease endpoints to support all of these conclusions so you can always play devils advocate (and many lucratively do)...but none of the available data points to Americans needing to eat more saturated fat.

This is why all major guidance emphasizes replacing saturated fat with mono- and poly-unsaturated fat sources and if there's a relevant option to substitute a satfat rich source with carbs, choosing fibrous ones appears best. The trial data and cohort align reasonably well on this.

most folks have replaced satfat intakes w high intakes of refined starches & sugars, themselves not great for several CVD risk factors. When folks advocate for eating more satfat saying it's 'healthy' they're almost certainly relying on comparisons of satfat vs refined carbs -a nutritional strawman

When you see high vs low satfat intake not associating w CVD, that could be bc there is no relationship,or it could be bc people eating low satfat eat more of something that is equally risky for CVD (thru ApoB or non-ApoB-mediated risk). The latter is what the thinking in the field is currently

The SatFat story is largely considered to be an issue of substitution - when you eat less satfat, what do you eat instead? Nutrition has no placebo and requires pairwise comparisons of all potential replacement sources of calories to rank nutrients/foods in relation to each other & disease risk.

SatFat-CVD is emblematic of the challenges of linking nutrition to chronic disease risk, casually. Dietary factors typically modestly influence chronic disease risk factors, which are themselves only partial determinants of chronic disease risk

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.

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
