Nutrition in Obstetric Practice: What OBGYNs Actually Need to Know
A WHTReport on the HHS Medical School Nutrition Initiative, Where the Reform Should Really Start, and the Technology Changing Nutritional Care
On March 5, 2026, HHS Secretary Robert F. Kennedy Jr. and Education Secretary Linda McMahon announced that 53 medical schools across 31 states have committed to require at least 40 hours of nutrition education for students starting in fall 2026. I agree with this direction. In fact, I have been saying it for years. The average US medical student currently receives about 1.2 hours of formal nutrition education per year. Fewer than one in four US medical schools required a nutrition course as of 2024. That is not a curriculum gap. That is a curriculum failure.
This report is not about the politics of the announcement. RFK Jr. made some claims that go well beyond what the evidence supports. I will leave the carnivore diet commentary to others. What I want to do here is more useful: tell OBGYNs specifically what they need to know about nutrition, what they should be counseling at every prenatal visit, and where the evidence is solid versus still evolving.
But I want to start with an argument the HHS announcement barely touches. Forty hours in medical school is better than 1.2 hours per year. It is still too late.

The Problem Starts Long Before Medical School
“Dum differtur vita transcurrit.”
Seneca, Epistulae Morales, 1.1 | “While we delay, life passes.”
A future physician arrives at medical school having already formed her dietary habits. She has eaten through 22 years of childhood, adolescence, and college on whatever her family, school cafeteria, and college dining hall offered. She has spent late nights studying on pizza and energy drinks. She has never had a single structured lesson on what food does to the human body. Now, in year three of a four-year medical school program, she will receive 40 hours of nutrition education and be expected to counsel patients for the rest of her career.
We are building the house after the foundation has already set.
The HHS initiative recognizes medical schools as the intervention point because they are the easiest institutional lever to pull. But the evidence on nutrition education is clear: habit formation occurs early, and the period from adolescence through early adulthood is when dietary patterns are most malleable and most predictive of adult chronic disease risk. A 2021 systematic review in the International Journal of Behavioral Nutrition and Physical Activity found that school-based health education interventions in adolescents aged 10-19 years produced measurable improvements in fruit and vegetable intake and reductions in sugar-sweetened beverage consumption. The effect sizes were modest, but they were real. These interventions cost a fraction of what downstream chronic disease management costs. (6)
Two things need to happen alongside the medical school push. First, high schools should require nutrition education as part of a health curriculum, not as an elective, not as a unit inside a physical education class, but as a standalone, evidence-based course. Fewer than 1% of American children and adolescents currently meet recommended dietary guidelines. That number does not improve by waiting until those children are in medical school. Second, undergraduate colleges, especially those with pre-health tracks, should include applied nutrition as a core science requirement. A student who cannot name the function of folate or explain why protein intake matters for fetal brain development has no business counseling pregnant patients on those topics, no matter how many clinical rotations she completes.
The HHS initiative is a floor, not a ceiling. Forty hours in medical school matters. It also arrives 20 years too late to shape the physician’s own relationship with food. If Secretary Kennedy is serious about reversing the chronic disease epidemic through nutrition, the education reform needs to reach much further down the pipeline. The Department of Education is a co-signatory on this initiative. That opens the door. Use it.
