You Can’t Always Trust Nutrition “Research”…So What CAN You Trust?? | Marion Nestle






Hello, Health Investor!

Welcome back to another episode of The Health Investment Podcast…episode #50 to be exact!!

I can’t believe I’ve reached this milestone…and I’m honored to have such an esteemed guest here with me for #50!

Today, you’re going to hear from Marion Nestle.

Marion is Paulette Goddard Professor of Nutrition, Food Studies, and Public Health, Emerita, at New York University. 

She earned a Ph.D. in molecular biology and an M.P.H. in public health nutrition from the University of California, Berkeley.

From 1986-1988, she was senior nutrition policy advisor in the Department of Health and Human Services and editor of the 1988 Surgeon General’s Report on Nutrition and Health.

Her research and writing examine scientific and socioeconomic influences on food choice and its consequences, emphasizing the role of food industry marketing.

Marion has authored numerous prize-winning books, and from 2008 to 2013 she wrote a monthly “Food Matters” column for the San Francisco Chronicle food section. 

She blogs almost daily at, and her Twitter account @marionnestle has been named among the top 10 in health and science by Time Magazine, Science Magazine, and The Guardian.

In the episode, Marion shares how researchers’ conflicts of interest cloud nutrition research, which research we can trust, whether or not “superfoods” have any merit…and more! I honestly could have chatted with Marion for several more hours because I was learning so much. You’re gonna LOVE this episode! 

First, I wanna share an Apple Podcast review with you…

THIS IS THAT PODCAST! Brooke selects thought provoking experts to interview across a variety of health and wellness fields to get the juicy details on their insights for a long term healthier life. I’ve learned so much from this podcast due to the awesome guests and the way Brooke asks questions that get to the root of the topics, regarding not just what the subject matter is but HOW to incorporate it into your own life with small changes.I can’t wait for more episodes!
