In this on‑location video, David Perlmutter and a co‑speaker discuss chestnut flour while hiking near a wild chestnut tree in Corsica. They highlight chestnut flour’s key advantage of being gluten‑free and present its detailed nutritional profile per 100 g: 3.7 g total fat (with poly‑ and monounsaturated fats), 78 g carbohydrates (including resistant starch), 9.2 g dietary fiber, 21 g sugars, and 6.5 g protein. The conversation explains resistant starch as a prebiotic fiber that supports gut bacteria and promotes short‑chain fatty acid butyrate production. Visuals show the chestnut’s protective outer shell, how the nuts develop on the tree, and the surrounding Mediterranean landscape. The segment encourages viewers to consider incorporating chestnut flour into their diet, emphasizing its nutritional benefits and natural origin.

Hi everyone. We were hiking and stumbled upon this wild chestnut tree, and I thought I'd spend just a few moments in, in talking about chestnut. You know, there's a lot of people making flour out of chestnut, so let's have a look at just some of the nutritional information related to chestnut flour. One of the main advantages of chestnut flour is, of course, it is gluten-free. Let's have a look at the nutritional content of chestnut flour, and recognize this is 100 grams, which is—it's quite a bit of flour. The total fat content is 3.7 grams, and you'll notice that it does contain good levels of both polyunsaturated fat as well as monounsaturated fat. And the carbohydrate content is 78 grams, and again, that's in a full 100. Grams of chestnut flour.
We'll talk about that in just a moment. Dietary fiber, 9.2 grams, which is really good. And sugars are about 21 grams. Total protein is about 6.5 grams, again in the 100-gram serving. So let's just for a moment talk about the total carbohydrate. And some of this is represented by what we call resistant starch.
And resistant starch is a Very healthful prebiotic fiber tends to nurture good gut bacteria, enhances their ability to produce good things like the short-chain fatty acid butyrate. The sugar content, again, at 21 grams is quite a bit, but again, this is in 100 grams of chestnut flour. So when you find chestnuts, they're, they're buried in or Enclosed in this very protective, almost porcupine-like outer shell. And then of course the chestnuts are found within. And if you'll notice up here on the tree, that they— that's how you see them. They kind of explode up in the tree, and then the chestnuts fall to the ground and begin to germinate. So this is some information that's really, I think, interesting from several hundred Meters above sea level. That's the Mediterranean Ocean. We're above the little town of Sori on the northwestern side of Corsica. So let's think about this in the future. Think about the idea of actually consuming chestnut flour. And again, there's a great shot of a chestnut tree.
