Why?** I got a government brochure about preventing diabetes, and the nutritional advice was to reduce calories, increase fiber, decrease fat. It didn’t say anything about sugar. One of the speakers had a fast-food nutrition guide, and \[a sweet tea\] got ranked as a “healthy.” I asked him, “How can you characterize sweet tea, which has a ton of sugar in it, as a healthy drink?” His response was that there’s no evidence linking sugar to chronic disease. I just looked at him like, What? **So that led you to start digging into how industry was affecting public-health messaging?** I came across all of these references to the Great Western Sugar Co. The company was based in Denver, and sugar beets were historically a major crop in Colorado, so the company decided to donate many of their records to local libraries. In the first folder that I opened, there was a confidential memo with the Sugar Association’s letterhead on it. I was like, What did I just find? Are you kidding me? **What did the memo reveal?** It was a memo the Sugar Association sent out to its PR guys at various sugar companies about a report they had put together called Sugar in the Diet of Man. The report, which they put together with consultants, was meant to be a review of all the scientific research about sugar, heart disease, diabetes, tooth decay, obesity, etc. Of course, it ultimately concluded that sugar didn’t have a role in any of those things. **Your most recent research showed the sugar industry funded studies blaming fat instead of sugar as the leading cause of heart disease.** I don’t think we realize how much we’ve been marketed to. The whole “low-fat is healthy” movement allowed products high in sugar to be promoted as healthy. I don’t think the average person really grasps that there is industry money behind many food- and health-related studies. **Do you think Americans are catching on?** We’re in a time now where Big Soda is fighting the soda taxes, and the public is waking up to industry tactics. There’s a whole movement of trying to increase people’s awareness of food. **What needs to change?** Even though the science is clear that sugar contributes to heart disease, we’re still having these same debates about the role sugar plays in people’s health. I think my research can help us understand why these debates have gone on for so long. The tobacco industry still funds research, but the more high-quality, respectable journals have refused to publish it. That hasn’t happened yet in the food world. **Has your own diet changed?** I used to drink soda instead of coffee. That was a long time ago. **Do you consider yourself an activist?** That gets turned into sort of a bad word sometimes. I am taking action, let’s put it that way. I really want evidence to support what I’m bringing to light. I don’t want to just point the finger and say the sugar industry is bad. I want to document what they’re doing. I want the work to lead the way, and not have it be about me. **Many of your colleagues describe you as soft-spoken. Are you?** People don’t expect me to come out with the material I have. Because I am not preachy, people seem to trust me as reliable. I’ll take it. That’s who I am. I’m a proud introvert. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4606066/dr-cristin-kearns/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4606066/dr-cristin-kearns/"},"headline":"Dr. Cristin Kearns","datePublished":"2016-12-19T11:36:02.000Z","dateModified":"2026-02-23T02:21:58.990Z","description":"The former dentist turned investigative researcher is exposing how the sugar industry got us hooked","url":"https://time.com/4606066/dr-cristin-kearns/","keywords":[],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt5be33c40c68d3fac/6988b3adcf40a81131c45e92/cristin-kearns.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alexandra Sifferlin","jobTitle":null,"url":"https://time.com/author/alexandra-sifferlin/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt5be33c40c68d3fac/6988b3adcf40a81131c45e92/cristin-kearns.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"cristin-kearns","caption":"Cristin Kearns","creditText":"Helena Price","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/4606066/dr-cristin-kearns/","name":"Dr. Cristin Kearns"}}]}] ```
