The answer
They are different plants. True yams (genus Dioscorea) are native to Africa, starchy, dry, white-fleshed and bark-skinned, while sweet potatoes are in the morning glory family. Most US "yams" are soft sweet potatoes; the mix-up goes back to the African word "nyami".

[00:00] Art Coalson, I think it's time for an under Google bull. What do you got for us this week? [00:17] Super excited [00:25] In the end it's gonna be better and more true than Google can give you [00:30] So was Thanksgiving last Thursday and [00:34] And [00:35] You know enjoying the sweet potato pie and the candy yams and I thought to myself [00:43] These taste the same [00:46] I'd like to know what the difference between a sweet potato and a yam is [00:53] Mm-hmm. I used to know this. I feel like I learned this fact [00:57] once every three years or something [01:02] Joey you're just a vegetarian you must know [01:04] I'm not very picky. I don't do much research into what I put into my mouth [01:13] Fantastic [01:16] So, I guess my first question is that's what she said for sorry, I'm sorry. Oh, no [01:23] Is there a difference at all is it to you know that something has two different names, but I [01:31] Don't know [01:32] that's what I have always thought is that they are the same thing just [01:38] you know if you're from [01:40] the [01:41] North you call it a [01:43] Sweet potato and if you're from the south you call it a game or the opposite. I can never remember [01:48] I don't know. Does that make sense? Yeah, yeah, like I don't feel like I've ever been at a grocery store [01:55] That had both sweet potatoes and yams [01:58] See, I feel like I have [02:02] Hmm [02:03] But they're like next to each other [02:08] You think they just said ran out of they just ran out the they didn't have like two signs [02:15] Well, no, they're no it's like I mean, they're they're both saving print. They're both like they root vegetables that look [02:22] similar, right, but they like I [02:26] Feel like they're negative [02:27] Maybe maybe they're just fooling me by giving me the same thing and having two different signs depending on which region I'm from [02:34] I think that's what we got here [02:36] We got a a duff beard duff light duff ice situation where it's one tube and it branches out into the three [02:44] Different bins and it's all the same thing. Okay, you think that one of them might cost more money, even though it's the same thing [02:51] Hmm. Hmm that I don't sure yeah [02:54] Make you pay a little bit more for that. Yeah, cuz it sounds exotic [02:59] Does it I don't know [03:03] sweet potato [03:06] What if it's not the same thing, what if it's just a completely different [03:11] thing [03:12] Like what if it's a an animal or something, you know, like how the alpaca and the llama we thought it was the same thing [03:19] But it was different [03:21] Yeah [03:23] They were very close they were I mean, that's what I assume I assume they're closely related but [03:29] They could be different. So I think we've got two options. I think one is that they're closely related or [03:34] the other option is that they are [03:37] The exact same thing with different regional names [03:41] Our option three is that uh, it's a marketing ploy [03:46] Right like a hardy's and a carl's junior situation. Yeah, what's the rallies and checkers? Mm-hmm. Yep [03:54] So it seems like it's a little bit [03:56] More subtle than that. So it so it's like a venn diagram thing here. So yam is a type of sweet potato [04:05] oh [04:06] But there are many types of sweet potatoes. I believe is what i'm getting [04:11] Yeah, so a true yam [04:13] is of the [04:15] discoria genus [04:17] Diasporia genus and is generally imported to america from the caribbean [04:22] Uh, it is rough and scalene very low in beta carotene. Are you getting that? [04:27] yams are from lilies [04:30] They're part of the lily family and sweet potatoes are part of the morning glory family [04:36] Hmm. No, I did not see that. Yeah, uh that the yams are native to africa [04:43] Mm-hmm [04:46] And sweet potatoes are grown in the u.s [04:49] Sweet potatoes only in the u.s. Does that seem right? [04:51] um [04:53] It seems like there's two types of sweet potatoes the firm sweet potato and the soft sweet potato which is has the [05:00] Uh, the soft sweet potato has the copper skin and orange flesh [05:05] And that essentially what? [05:09] Grocery stores are doing is selling [05:13] the two different types of sweet potatoes [05:16] One is a sweet potato and one is a yam [05:18] because true rams yams are african [05:22] And starchy and not very good [05:24] Yeah, so what i'm seeing is so the the pictures that i'm seeing of what a yam is looks significantly different than what a sweet potato is [05:32] Yeah [05:34] So yam has like a bark like skin [05:37] That's more brownish whereas the sweet potato has like a reddish brown [05:42] Kind of skin and the inside of a yam is white [05:46] Yeah, so they're definitely different compared to sweet potatoes yams are less sweet and much more starchy and dry [05:53] So it's like it it's a mix-up. So [05:55] it seems like uh african slaves who came to the u.s called the local sweet potato nyami [06:02] Or yam, which is what they called the yam [06:06] In their native land, right? And so that introduced some sort of uh confusion [06:13] Well, apparently we're still confused [06:18] But I think so for [06:20] Yeah [06:21] So confusingly they are different things but people call sweet potatoes yams [06:28] I think is what is happening [06:30] I think yeah, this seems to be right [06:33] Um, they are definitely not the same thing [06:36] Correct clearly. There's a lot of confusion because we're still confused even though we've googled it [06:45] Yeah [06:47] I wonder why that there's so much confusion then [06:50] They're not the same thing [06:53] But it's like um [06:56] It's language man, you can't contain language people are gonna use what language they're gonna use [07:01] It's true [07:05] Joey I am what I am [07:10] Who's that who's that from I think that's popeye [07:14] Okay [07:15] Popeye Jones, huh? Yep [07:17] Okay [07:18] I think he said it about spinach. I think [07:24] All right, I think it's time for a break. Let me go see if I got some sweet potato pie in the in the fridge
