Potato Carb values

[staffsmatt]

Hi all,

Just wondering what everyone uses as the carb value for raw potato? (Just normal big potatoes) I've been using 0.2 per gram for ages but think it's a bit low (can't even remember where I got that from).

I can find values for boiled / jacket / mash but can't find just normal raw potato...

I'm also looking to confirm raw sweet potato values (0.15 per gram I think?)

Thanks

Matt

Spud Lite which are a 20% lower carb potato here in Australia are 9 grams carbs per 100 grams.

Most potatoes on the Waitrose website seem to have between 16 and 18g per 100g so 0.16-.18 per gramme.

Hi @staffsmatt

My old dietician taught me in ounces as she said it was easiest to remember: 4oz raw potato is 2 carb units/20g carbs, 6oz is 3carb units/30g carbs, etc That is, the carb units are half the weight in ounces.

I've found that works well for bolus calculations.

Oh that's fab thanks!

Thanks again!

Similar, I think, but I find that sweet potato has a different effect. It raises my BS less and is lower GI.

I tend to knock a bit off my bolus for it, but you'll have to experiment to see how it affects you.

Brilliant thanks again.

1 potato the size of a large hens egg has 10g of carb in it approximately. I was told this when I was diagnosed in 1965.

Brill - when I was pregnant I remember there being 2 egg size potato's on the food swap list !

Hi staffsmatt,

According to the DAFNE (Dose Adjustment for Normal Eating) Carbohydrate Portion List booklet, raw potatoes are 1.5 Carb Portions (15 grammes) per 100g.

Sweet potato (raw) is 2 Carb Portions (20 grammes) per 100g.

I was diagnosed in 1966 and was told the same. I have always counted potatoes as this and works well for me.

Oooops! I should have said 25% less carbs.

I had a couple of smallish ones with dinner last night.

Hello,

I am surprised if one has diabetes or pre, why one would even consider any potato raw or cooked? Did you know a cooked potato i.e. baked in oven ONE, equates to approx. ONE CUP OF SUGAR!

For this reason, why don't you consider, alternative pumpkin for example, which is lesser carbs and lesser than sweet potato.

To eat a potato, pasta, bread or rice, these will not lower reduce ones blood sugars, its as simple as that.

There are wonderful substitutes to try, pumpkin instead of potato, much nicer too. Make seed crackers instead of bread, grate coliflour instead of rice, and spiralize zuchinni instead of pasta, don't even cook it have it raw and crunchy, wow, its wonderful with fresh tomatos, garlic, olive oil sauce with basil thrown in.

Hope this helps

The OP is a type 1 @pollensa and with the right insulin dose (and timing) foods like the above can be eaten.

However some of your suggestions are good, love Pumpkin Soup and don't get me started on tomatoes & garlic.......lol

Hi staffsmatt,

Sweet potato (raw) is 2 Carb Portions (20 grammes) per 100g.

So why does the same portion size of sweet potato cause under half the bg rise as a portion of potato? I've been caught out by this a couple of times, because it makes sense sweet potato would have more carbs, but it sure don't digest that way.

What size potatoes are 15 grams?

What size potatoes are 15 grams?

Hi, you're replying to a very old thread and you're unlikely to get an answer from the earlier posters. 15 grams is about the weight of a compact disc (CD), so 15g of potato is not very much. A standard portion of potato according to the supermarkets' "servings" is in the region of 200g, so you'd expect 30g of carb in that.

Hi there, thanks for replying. I didn’t mean 15 grams as in weight, but as in 15 grams of carbs. The small egg size ones are 10 grams aren’t they, and the potato I’m referring to is a-bit bigger than that, about the size of the palm of your hand, about one egg size potato would fit into the other potato I’m referring to, so would you suggest it’s about 15 grams or more, I know it’s an old thread, but am struggling abit with counting carbs in potatoes

Have you got any scales? It's a bit difficult going off "egg-sized" and I'm not entirely sure whether you're referring to gram weight or gram carb content. There have rarely been potatoes in this house for the last five years, so I can't weigh any and show you a picture.

A potato that has 15 grams of carbs would on average weigh around 100g. This is based on the rough estimate that potatoes are around 15% carb (being otherwise mostly water). The internet says that one medium russet potato weighs about 170 grams or six ounces, and the potato is about 4 inches long. I would expect there to be around 26 or 27 grams of carb in that one potato.

The attached picture shows (or says it shows) one single 100g potato.

Does that help?

I’m referring to gram carb content, and a medium potato does contain about 26 grams of carbs, the one I’m referring to is palm size, at least I know now if it’s 100 grams, then it contains 15 grams of carbs and no I don’t have a weighing machine, but I need to buy one and thank you for the helpful info
