The Truth About Nutrition Science: Is The Government Getting it Wrong?

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.

We encourage you to share this interview so more people can understand the flaws in existing nutrition science and what we can do to fix it.
