I get a lot of questions about potatoes now. A potato is not a potato is not a potato. Let's start with a basic definition. So potatoes, like white potatoes or russet potatoes or even purple potatoes, are a American plant. They are part of the nightshade family of vegetables. And like any nightshade, unfortunately, they contain lectins primarily in the peel and also in the eyes like that. Sadly, potatoes, any of these potatoes, whatever color they are, are still mischievous from a lectin standpoint. And as I wrote about in Gut Check, one of my newer books, many of us react to a lectin that's called an aquaporin that's present in potatoes. That's not in the peel, that's not in the eyes. It's in the flesh. So even if you peel potato, it doesn't necessarily make it safe. But let's suppose you just have to have potatoes. Remember, these are starch storage systems for the plant. The plant relies on this as a storage system for nourishment when the sun isn't shining. The more concentrated the starch is, like in a red potato, the harder those starches are to break down. Unfortunately, we prefer the classic Idaho baked potato. And as all of us know, once we kind of cut it and squeeze it, all these kind of granules of potato that soak up the butter and sour cream, those granules are exposed starches. So we digest like an Idaho baking potato, far quicker into sugar than a waxy potato. So if you have to have a potato pressure, cook them to destroy the lectins. But then choose the more waxy varieties than the classic Idaho baker. And please don't have potato skins. That's where all the bad stuff is. And you can't make a pretty with sour cream and chives and bacon. All right, sweet potatoes. Now there's actually again, our underground storage system for the plant. There's actually a difference between a yam and a sweet potato. And interestingly enough, in grocery stores, they're often mislabeled so that this one, the Kind of orange guy is labeled as a yam, and this guy is labeled as a sweet potato. It's actually the exact opposite. Why is it interest? Well, for a nerdy detail, yams come from Africa and they're part of the lily family. And we all came from Africa long ago, so we were exposed to this tuber for a very long time. On the other hand, a sweet potato, which most of us kind of like, is actually part of the morning glory family and it's actually from the Americas. So we have not been exposed to this for as long as this guy. The problem is most people don't like this guy very much and they like these. When I was writing the Plant Paradox, we had two pages trying to explain the difference between these two and what to look for in a grocery store. My editor and I finally gave up because it was just too consuming to worry about.

On the other hand, your best choice is a purple sweet potato or a blue sweet potato. Now, this is sometimes called an Okinawan potato or Okinawan sweet potato. Why is it so good? Well, remember I told you that the denser the starch is, the slower you break it down into sugar. These guys are dense. They're much denser than yams and sweet potatoes. Number two, that blue color when you cut it open, or kind of reddish color, purple color. Those are anthocyanins. Let me see if I can break one of these. Yeah, there. Those are anthocyanins. Those are polyphenols. And what's interesting about the Okinawans, before World War II, everybody hears about the Okinawan diet. The Okinawans, about 80% of their calories that they ate were from the purple sweet potato. And many of the ancient Okinawans believed that their longevity and I think they're right was because this was basically their food. So again, why was it so good? It's a very, very dense starch. It's loaded with polyphenols. And the denser the starch, the more tough, harder to break down, the slower the carbohydrates are released as sugar. And the other huge benefit is a lot of these starches are resistant to digestion resistant starches. So they then become food for healthy bacteria in our gut. And if you've listened to me long enough, you know, the happier you make your gut buddies, the more they take care of you. Which really explains how the Okinawans, unlike the rest of their Japanese counterparts, had this longevity benefit. It was because of their purple sweet potato. So look for these guys. They're becoming more common in the grocery store. Yes, they're really ugly, they're really weird looking. Don't let that be off putting. And yes, they are waxier than a sweet potato. But these are your best bets. Having said all this, when I tell my patients that sweet potatoes are a much better choice, yams are a much better choice. Many of my patients say, well, that's a better choice. So I can have as much of these things as I want because they don't have any lectures. And Dr. Gundry said, They're a good choice. And they kind of go all in. And just this past week, I saw a patient whose triglycerides were going up, his insulin levels were going up, his insulin resistance was going up. And I said, something's changed in your diet. He said, oh, yeah, I have been adding sweet potatoes every day. I have a sweet potato fry for breakfast. I'm having sweet potato soup several times a week. It's sweet potatoes because they're so good for you. Not so fast. Adding these starches, even though they're safe starches, they're still a starch. And most of my patients, starches because they have high insulin levels, because they have insulin resistance, are still mischievous to them. Are there better swaps? Well, make a cauliflower or celerac root mash, have shirataki or konjac root potatoes, have hearts of palm, have a rutabaga, have a turnip, and by all means try jicama fries. They work great as a substitute. So best are the purple sweet potatoes. You begin to see them. Second best are the yams, the ugly ones. The other reason is you probably won't eat as many of these as you will of these orange guys. But really keep the real potatoes away. Even if they say blue or Orange. Those are still potatoes.

This question comes from Sarah Ward 7350 on YouTube. On my episode about the four day gut health reset, they asked do you eat breakfast or snacks or just lunch and dinner cabbage soup? Well, whatever you want to do will work for you. Personally I prefer just the lunch and dinner cabbage soups but but other people do fine by having a breakfast with or snack. So however works for you is the way it will work. The review of the week comes from ickyhisbeloved. On my YouTube episode about the Chicken and the Sea diet. They said thank you Dr. Gundry heart emoji. This is an answer to prayers. I've been ill for some time, diagnosed with autoimmune disease, losing too much weight. All the symptoms you discuss regularly but not sure what to eat to turn this all around and you address this tonight. I can't wait. Thank you doctor. You know, we've seen many of my really good patients still struggle with leaky gut. Even eating all the approved foods on the Plant Paradox diet. And with the Chicken and the sea, we're eliminating really basically all the other potential mischief makers and that's what really turns things around for a lot of people. The good news is many people don't lose weight on this program. They actually gain weight because they've repaired the wall of their gut and they can absorb more vital nutrients.
