Mushrooms? How much carbs do they really have?

[Fracmeister]

Maybe I am getting the wrong ideas or maybe I just eat too dang many mushrooms… I will sauté maybe 8 ounces of shrooms in butter with a dash of Worcestershire and my carb counter has like 10 grams of carbs which seems like a lot for something that has practically no calories…

Depends on what kind of mushroom, probably.

For example, the USDA Food Composition Database says that white button mushrooms have 4.08 g of carbs per 100 g. Portabella are 4.66 g / 100, shiitake are 8.17 g / 100, and raw chanterelles are 6.86 g / 100.

According to NCCDB database…and just from memory by looking at labels from store purchases…the white packaged mushrooms you get at the store are about 1.5g net carbs per 100g raw. Chestnut mushrooms have about 0.5 net carbs per 100g raw. Portabella around 2 net carbs per 100g raw.

Shiitake and Enoki are at the higher end with around 4.5 net carbs per 100g raw.

I usually get Chestnut mushrooms but really…mushrooms are one of the foods I certainly do not have to worry about on keto.

Same here … we often top our steaks and burgers with sauteed mushrooms. My assumption is that the cooking (which typically shrinks the mushrooms significantly) may also release carbs in the process, similar to how fermentation does the same to vegetables.

Fact or wishful thinking? Either way, mushrooms are a kind of health food as far as I’m concerned.

yea I get counts lower but it is what 'shrooms you are eating.
like from the net: Mushrooms are low in carbohydrates. For instance, a cup of whole white mushrooms just contains about 3 grams of carbohydrates. Although mushrooms are technically fungi, they are considered white vegetables — like onions and garlic — with a low GI of 10–15 and a GL of less than 1 per cup (70 grams), meaning that they won’t spike your blood sugar levels

It seems 10g for 8 oz is kinda off on the calculator??

I have eaten sauted and grilled chestnut mushrooms regularly throughout my Keto journey. Quick, cheap, tasty and never had an issue with being any ‘hidden’ carbs - although would be interested if any science says otherwise.

If I grill them I tend to put some avacado oil on them first.

I realize this snippet came from the internet (i.e., not something said by @Fangs) but it really did crack me up:

…Although mushrooms are technically fungi, they are considered white vegetables…

Mushrooms are not technically fungi. Fungi is what they are. There’s nothing technical about it.

I’m not sure who out there “considers” fungi to be vegetables… white vegetables, no less. But apparently, after due consideration, assigning a specific color to the thing they are not also matters to these sharp taxonomists.

In conclusion, I suspect there may also be people out there who consider vegetable oil to be a good choice for frying potatoes - white potatoes.

Technically, vegetable oil is an oil. But its best application is for lubricating small motors. Not for lining one’s coronary arteries.

Mushrooms are fungi, clearly. And vegetables (for many people, at least) as it’s a kitchen term or how should I call that. Nothing to do with its scientific classification.
But why white? Tons of mushrooms aren’t white… Some are even color changing! There is a tasty small one, it has orange flesh but it becomes purple when cooked… If I remember well but I think so. And many gets red or blue or black when cut. But sometimes they are simply bright orange.

I don’t know the carb content of most of the mushrooms I have eaten but I don’t care about that much, I eat little mushroom. I ate little mushroom, more like, it’s about zero nowadays. If I want to track it and don’t find the data (but many has data somewhere), I use some carbier one and that’s it.
But they aren’t particularly carby normally… Not super low-carb in some cases but the carbier ones are often stronger so less is used…?

Colors are so… Not correct in many cases. There are white sweet potatoes…

Never having been in a kitchen where mushrooms were considered a vegetable, I can’t speak to such terminology.

Then again, I’ve been in many kitchens where other menu items were considered food, and they clearly weren’t. So I’ll refrain from further comment.

I eat a great deal of Mushrooms, and though I don’t have a container here now to check, I do know the Carb count is minimal. I get the Blue Tubs from Food Lion, which are either White Mushrooms or Baby Bella, sliced. But have checked both years ago, and never thought either would be a problem. And I do usually do a tub with a Steak, two if my Son is planning to eat some. But also add them in some other meals as well, and they make a nice addition. … But again, I never worry about over-carbing with them.

I always have placed emphasis on things like this as follows. Do they make me want to eat more? If I did eat “too much” of this, would it affect my blood sugar in a bad way? For both of these questions and mushrooms, my answer is No. I don’t want to eat more mushrooms, and it would be extremely hard to eat so many mushrooms they affected my blood sugar.

Unlike, say, real pizza or ice cream.

I’m not sure who out there “ considers ” fungi to be vegetables…

For the purposes of marketing and the food laws, the U.S. Department of Agriculture does. Just as it does the various savoury fruits that we consider vegetables (tomatoes, beans, cucumbers, squashes, and the like).

There is a difference between scientific classification and how we use things. Also, the kingdom of Fungi was considered part of Plantae until fairly recently, as the history of science goes, and there are some of us old enough to remember when mushrooms were vegetables!

Ah, yes, the US Dept of Agriculture. The fine folks who classified Heinz Ketchup as a vegetable.

Point(s) well taken, sir!

Even when I was a schoolchild, yes. I still can’t wrap my head around it, they are so obviously NOT plants… Oh well. We know better now.
Once I wanted to learn all the kingdoms… I run into all the varieties in the past… I still am not sure about it all… But one day I will learn that. And all kinds of star evolution (according to humankind’s knowledge, at least).

Back to mushrooms vs vegetables. Mushrooms are vegetables according to zillion people. I don’t mind that, I only have problems with people putting eggs together with dairy…
