Rachel Feltman: Happy Halloween, listeners! For Scientific American\u2019s Science Quickly, I\u2019m Rachel Feltman.<\/p>\n
Halloween is pretty much my favorite holiday. That\u2019s mostly because of the crisp autumn weather and the spooky vibes, but I certainly don\u2019t mind an excuse to eat way, way more candy than usual. But what does this annual sugar splurge mean for the microbes that live in our guts? The answer isn\u2019t as scary as you might think\u2014the trick is choosing your treats wisely.<\/p>\n
Today\u2019s guest is Chris Damman, a clinical associate professor of gastroenterology and medicine at the University of Washington. He’s here to tell us how our candy consumption can help treat\u2014or trick\u2014the critters that haunt our guts.<\/p>\n

Thanks so much for coming on to chat with us today.<\/p>\n
Chris Damman: Yeah, no, it\u2019s great to be on, and thanks for the invitation.<\/p>\n
Feltman: So as a gastroenterologist when you think about Halloween what are the big concerns that come up for you?<\/p>\n
Damman: Well, that\u2019s a good question. When I think about Halloween, first of all, it\u2019s one of my favorite holidays …<\/p>\n
Feltman: Same here.<\/p>\n
Damman: Always has been, you know, tracing all the way back to high school and Halloween window paintings. And, you know, of course candy comes to mind, when you think about Halloween, in addition to fun costumes and kids in pumpkins.<\/p>\n
In terms of concerns, I\u2019m a pragmatist, a realist, when it comes to nutrition, and my kids remind me of this as well, that it\u2019s okay to cheat every now and then. And I think holidays are one of those times when it\u2019s probably okay to relax a little bit around nutrition. Candy is a treat and should be treated as such. Halloween is a holiday of tricks and treats, so [laughs], so there you go.<\/p>\n
But, you know, moderation, ultimately, is a guiding light, and moderation can happen any given day but also can happen over the course of weeks and months.<\/p>\n
Feltman: Well, and you wrote a piece for the Conversation last Halloween about the gut microbiome specifically that I thought was, was really interesting. Like you said, holidays are great cheat days, and somebody who\u2019s mindful about their sugar intake all year is certainly not gonna get in trouble enjoying some candy on Halloween. But how much does that hold true for our gut microbes? What do we know about what getting a sugar overload does to them?<\/p>\n
Damman: So our microbes, when they see sugar, there are certain bacteria that are present in our microbiome that thrive on sugar, and they just happen, unfortunately, to be the ones that tend to be a little bit more inflammatory. And so they can cause gut inflammation; they can cause inflammation throughout the body.<\/p>\n
And so when we treat ourselves to Halloween candy we\u2019re also treating those less savory microbes to a Happy Meal, which ends up, often, with not feeling so happy in the end [laughs]. We pay the consequences.<\/p>\n
But not everyone responds equally to any nutrition, and some are going to have more of those microbes; some might spike their blood sugars more because of underlying health conditions. So\u2014and ultimately, a lot of nutrition is really about listening to your body and how you feel.<\/p>\n
Feltman: Well, and you talked about in your piece, you know, how some candies might be friendlier to your good gut microbes than others. Could you tell us a little bit about that?<\/p>\n
Damman: This is something I\u2019m really passionate about. I don\u2019t think, you know, all processed foods are equally bad. Certainly, you\u2019re going to be best off having a whole food always, but I think there\u2019s some processed foods which are better than others, and that\u2019s true for Halloween candy as well.<\/p>\n
Now, if you\u2019re going for lollipops and Starbursts and Skittles, you know, which are really just pure sugar and there\u2019s, you know, colorings as well present in these foods\u2014that\u2019s going to be less healthy than if you reach for something that has whole nuts in it, like a Snickers or a Payday. Or, you know, heaven forbid, have a candy apple with a, a full apple in the center. A candy that has elements of whole foods is going to be better for you than a candy that\u2019s almost purely processed sugar.<\/p>\n
And then intermediate to something like a Payday and something like a Starburst would be a peanut butter cup. You know, there\u2019s still good, wholesome peanut butter, mixed in with lots of sugar, but that peanut butter still retains a lot of the original elements of the peanuts that were used to make it.<\/p>\n
Feltman: And could you tell us a little bit about, you know, what\u2019s going on in our guts when we digest those whole foods that makes it better for our gut microbes?<\/p>\n
Damman: You know, I feel like our nutrition conversation at large has been very much around the things that are bad for us and we focused on the sugar, the salt and the fat. And that\u2019s certainly a piece of the puzzle, and I wouldn\u2019t characterize \u2019em as bad; these elements of food are incredibly important, and it\u2019s really a matter of missing the balance.<\/p>\n
And with balance, while there are things that we get too much of, there are also things that we get too little of, and we\u2019re starting to hear more about this, things like fiber and phytonutrients, polyphenols. These are the types of things that are often processed right out of foods and that are missing in the ultra-processed foods.<\/p>\n
So when we talk about rebalancing our diet it\u2019s really about bringing some of these things back in. And what\u2019s fascinating is these elements are often as good for our microbiomes as they are for us, and our microbiomes transform them into elements like modified polyphenols and things called short-chain fatty acids that are incredibly important for our body\u2019s health in regulating our immune system and our metabolism and even our brain.<\/p>\n
Feltman: So obviously, there are a lot of things about a big sugar spike that might make you feel not so good, but if we\u2019re talking about the gut microbiome specifically, what are things that people can do in the days after a day full of treats like Halloween to really support their gut flora?<\/p>\n
Damman: [Laughs.] Absolutely, you know, so after a day of indulgence it\u2019s best to get back on the health bandwagon, so to speak. And there are certainly, you know, things that are healthier to eat than others: naturally, whole foods. And that would be all the things that you normally hear about as being healthy: fruits and vegetables but also whole grains and legumes like beans, nuts and seeds\u2014these are things that are often forgotten but actually incredibly important. Refocusing your diet back on those types of foods can help your body recoil [laughs] from the indulgence of Halloween candy.<\/p>\n
Feltman: Well, thank you so much for coming on to chat. I hope you\u2019re having a happy Halloween and enjoying some treats.<\/p>\n
Damman: Yeah, wonderful, and, and likewise, similar well-wishes to you and your listeners. Happy Halloween.<\/p>\n
Feltman: That\u2019s all for today\u2019s episode. We\u2019ll be back on Monday with our weekly science news roundup.<\/p>\n
