Is nutrition research getting the support it needs to inform public health policy?
Despite the rise in chronic diseases related to lifestyle factors like diet, nutrition research only receives $2.2 billion of the $30 billion NIH budget.
At first glance, this may seem like a lot of money, but its utilization is spread thin, and, as Dr. David Ludwig and Gary Taubes highlight in this interview, it’s primarily used to fund misleading short term trials that confirm existing nutrition biases.
However, if we want to actually address the chronic disease epidemic, we must increase the resources allocated to nutrition research AND the quality of that research.
In this video, journalist Gary Taubes and Harvard endocrinologist Dr. David Ludwig expose the core problems in today’s most cited nutrition studies and offer a bold new path forward.
In this conversation, you’ll learn:
Why short-term feeding studies can’t tell us much about chronic disease How confirmation bias shapes which nutrition studies get funded, published, and accepted by the medical community and policy makers The major flaws in NIH-funded research comparing low-carb vs. low-fat diets Why the focus on ultra-processed foods is only part of the solution How we could design better long-term studies that actually help people get healthier
It’s time to question the status quo and demand better utilization of research funds to inform public health policy in a way that can impactfully improve the health of our population.

The Truth About Nutrition Science: Is The Government Getting it Wrong?
This video features a discussion on the shortcomings of nutrition research and its impact on public health policy, particularly concerning the rising rates of obesity and diabetes. Experts Gary Taubes and Dr. David Ludwig analyze the challenges in nutrition science, the effectiveness of current studies, and propose how to improve research methods moving forward. They emphasize the need for long-term, well-funded clinical trials that explore the low-carb and processed food diets, questioning the biases in interpreting nutrition studies.
Key Points
Confusion in Nutrition Science
Many people feel lost about nutrition due to conflicting studies and beliefs. The current state of nutrition science has not effectively addressed chronic diseases like diabetes and obesity.
Funding and Research Quality
Nutrition research is severely underfunded compared to pharmaceutical studies, which leads to insufficient data on effective dietary guidelines and the underlying causes of obesity and diabetes.
Issues with Current Studies
Many of the prominent studies suffer from design flaws and biases, particularly studies that confirm pre-existing beliefs within the nutrition community, leading to misleading conclusions.
Need for Better Studies
A call for longer, well-supported clinical trials focusing on the carbohydrate insulin model and low-carb diets. These studies should take into account real-world food environments and patient adherence.
Ultrarocessed Foods Debate
While ultrarocessed foods are commonly viewed as unhealthy, the discussion around their impact lacks thorough scientific examination, and more nuanced, detailed studies are needed.
Challenges for Professionals
Health professionals struggle to recommend diets that have not been broadly validated through rigorous, long-term trials, which limits their ability to provide effective dietary guidance.
Opportunity for Change in Research
With new leadership in nutrition research agencies like the NIH, there may be an opportunity to reshape the focus and funding of future nutrition studies.
AI and Nutrition Precision
The potential for using AI in personalized nutrition may complicate the situation further. Experts stress the importance of foundational studies before tailoring diets to individual needs.
The discussion about metabolic studies not accounting for the carry over effect is illuminating - if that is intentional or just flawed study design is left as a exercise for the reader.
