Rinsing cooked rice

Hi all, just made a rice salad and as the rice needs to be fast cooolled I’ve run it under cold water after cooking it. It’s just dawned on me, am I washing carbs away as starch will run with the rinsing water.
 
No. The carbs aren’t sitting on the outside waiting to be washed away, they’re inside the rice and a key part of the structure.

Isn’t starch a carb? When you don’t rinse it you still have an amount of starch on the grains of rice.
 
If you don’t believe my answer, try googling it?
Sweetly it’s not about not believing you, it’s understanding the process, I’m 57 years young with many years experience of cooking. Rice contains starch and some starch gets washed away when rinsing before you cook if you rinse it then and after cooking. When you boil rice you can see starch come out of the rice. Therefore when you drain the rice you’re loosing so much starch . That would be taken into account when you see the carb etc figures of the cooked rice value on the packets. If you intend to use rice cold in a rice salad it’s advised you rinse it under cold water to cool it quickly (because rice can grow some sort of food poison bacteria especially in this weather) . Now if you watch the water as you rinse it you can see more starch come away from the rice. Now I know my carb count from normally cooked unrinsed rice works. Therefore my query on the change in carb value is valid. Your answer made me wonder if you’re understanding the process of cooking rice.
 
I see what you was thinking Gill I don't think there was any need to talk to you like that, but then I've noticed it isn't the first time

Thank you Ian , I’m ok, for certain circumstances that I have experienced over the years I let this wash over me as there can be valid reasons that we may not be aware of as to why we can see responses like this from anyone.

You are indeed washing away carbs - but they are in a layer on the outside of the grains - you aren't actually reducing its carb content, it is still about 2/3rds carbs - you just washed some of the rice away, 2/3rds of which were carbs.

Yeah I know lol but what I’m trying to get to the bottom of is whether is a significant amount . If unrinsed cooked rice carbs is significantly different to rinsed carbs then I could mean the difference of half a unit in carbs for me even if it’s a small amount. In other words if it equates 150gms of rice is lower by 6gms of carbs that’s half a unit. Thinking about it now writing that out I don’t think it would be that much

If you wash 150gm of rice you might reduce it down to maybe 140 or even a bit less - but the 140gm of rice left in the sieve will still be 2/3rds carb - there will have been some starch left in the cooking water if that was how it was prepared - it can be used as glue, like flour paste.
I think that the main thing is consistency - I depend on it to control my type 2 by diet alone - so if you prepare your rice in as close to exactly the same way as possible each time, checking the weight you eat and your reaction to it that could provide some stability - I know that you have many more variables to contend with, but taking control where you can should at least avoid any uncertainty about what you actually put on your plate.

I’ve never noticed a significant difference between rinsed and unrinsed rice. I still base my carb counting on the dry-weighed rice.

I generally rinse the rice before cooking, and these days aim for the full-absorption no-rinse method, rather than cooking in heaps of water and draining like I did as a student.

Your rice will weigh less because you’ve washed some of it away. If you’re still eating 150g whether you wash it after cooking or not then you’re still eating the same carbs. You’ll just have more grains of rice if you counted them all in the washed plate.

I’m autistic and it’s hard to communicate in writing but my intentions are always to help people. Some members of the forum got upset at me putting the explanation of autism in my signature so I had to remove it.

If us on the forum can’t give a detailed enough answer to satisfy someone’s questions then suggesting they research further on Google is just a sensible move to get more information. Nothing mean about it and I’ve no idea why you’d say “no need to talk to you like that” - I literally don’t have a clue what that means. That I can’t suggest Google?
 
My thoughts are that if you kept that rinse water and evaporated the water off, you would probably be left with enough starch to make a grain or two of rice but not much more, so I suspect the loss of carbs will be negligible.

@Lucyr I’m so sorry to read that Lucy. That’s shocking that you had to remove it. We are allowed to say we have Diabetes and other conditions in our signatures arnt we? Yes on the one hand you shouldn’t have to feel the need that you have to explain it but on the other hand not everyone knows what autism is and can do so your explanation would “educate” those who don’t.‍♀️ My daughter has severe EUPD and has her “way” with words. I always try to be mindful how I use my words and put sentences together for her but don’t always get it right . When I get it wrong and she comes out with a response that would otherwise seem awkward and uncomfortable to most I just let it was over me.

I had actually googled about the rice and it was inconclusive which was why I came here where the real lived experience is. I’ve found I have some answers that make sense now.
 
Can I throw in my two-penneth about the numbers? I am sure that washing rice before or after cooking will remove stuff which more than likely will be mostly carbohydrate but the amount will be small compared with whats left and is best ignored when looking at the bigger picture.

Carbohydrate is a portmanteau term and includes all sorts of compounds from simple sugars to complicated starches and bundling them all together under one heading is bound to lead to what might be seen as inconsistencies and things that do not sound right. They are not, they are just just a consequence of the way things are done. As far as I can make out, the values quoted and used are not super accurate measurements made in a laboratory but good guesses made by people who know what they are doing. I am sure the values quoted for rice are the same, and the error in the estimate will be larger than the weight of stuff removed when it is washed.

If you want an analogy, think of a sundial.... very good to see roughly what time of day it is, but you would not try and use one to time a 100m race. Carbohydrate numbers are very good for telling you where something fits on the very low to very high scale. Just don't try and be too clever when using them. Same message I try and put over when it comes to blood glucose readings on a hand held meter.

Following on from the reference to the fact that carbohydrates include a lot of different compounds, I have read that chia seeds contain a lot of carbohydrates but the majority of them are fibre which is not digested.
 
Yes @JimG. There is no problem in looking at complicated things simply, provided you do not forget where you are starting from. The fun starts when you look for subtleties in interpreting what you observe when like as not, all you are doing is paddling about in the errors.
 
I often think these things are a bit like the variation in the speed you are doing depending on which display you look at, the car digital display can show as much a 5mph difference to the sat nav and that will vary depending on what speed you are actually doing or whether you are accelerating or slowing down. So your best guess is all you can go on.
 
I am in the "yes, there are carbs (starch) in the rinse water but not enough to make a difference" camp.

I always go back to the amount of estimates and approximations that we make with diabetes and insulin dose calculation means little variations make little difference unless we are way off with out other estimates and approximations like
- how much carbs are actually in the rice before rinsing. E.g. the starchiness of the drained water depends upon how long you cook the rice (unless you are successful with the absorption method of cooking).
- what is our starting BG (our meters may be up to 15% out)
- insulin to carb ratio
- rounding up (or down) to whole (or half) units of insulin
- the impact of everything else that is going on (like stress and exercise) on our BG.
