Carb Sources

MrNice

Hi,

Anybody used brown rice flour or potato starch flour as carb sources? i was thinking that mixing them in with soups (probably make gloup) etc...

The brown rice flour is 78g/100g starch and am I right in thinking that brown rice is low GI - I'm guessing that the processing of this into flour wouldn't alter the GI value??

Any idea's on the GI of potato starch? Its 86g/100g carbs which looks pretty impressive to me

Do you mean Potato Starch Flour or Potato Flour mate?

Either way if they are in soups whatever you put in the soup will affect the GI

MrNice

Not sure what you mean mate. Mainly just wondering if anyone used them as a supplement..I'm pretty sure that brown rice is has a low GI, but not sure on the the potato starch flour. Need to vary my diet - reaching oat overload!

Sorry if I wasn't being clear mate.

I was just checking if you meant Potato Flour or Potato Starch flour - they are both different things. I dont think they are as low GI as the brown rice flour.

Re the soups - if you made carrot and corriander soup with the brown rice flour the the total GI of the soup would be higher than the GI of the brown rice flour due to the ingredients.

How much carbs you taking in per day mate?

MrNice

Hi TH&S, yeah I thought that potato starch's GI was higher than brown rice flour, I've looked on the net for the GI for it but can only find answers for whole potato preparations (mashed, boiled etc...)

I understand that if I mix the flours with other ingredients then the overall GI would differ, but it would only be an average in proportion with the amount and GI of the other ingredients. This can't be helped I suppose - too much a wimp to take the stuff in just water

I wonder as well if the fact that it has been mechanically processed alters its bioavailability - I would guess that due to the increased surface area it would be absorbed at a faster rate then say, a normal rice grain, or a spud!

I'm aiming for 375g of carbs a day. Having trouble managing this amout I have to say though.

Tall

meh! You even got me confused with that one.

You really struggling to get 375g down your neck?

I dunno what you are eating but heres how I get some of mine ( I dont have this every day, just a selection of the following)

2 x 75g oats in whey shakes
150g to 300g in wholewheat pasta (Mac cheese! yum!)
150g to 300g in sweet potatoes
100g in brown rice

We make home made curries from fresh too which we put sweet potatoes in and have the brown rices with.

Hope that helps somewhat.

Are those weights dry or after preparation? 250g of cooked rice contains about 60-70g of starch.

About the bioavailability -lol - I was just wondering if the absorbtion rate was increased as the food had already been broken down into smaller parts that would be easier to digest.

Those were dry weights mate - can never be bothered to get my scales mucky... If it dont wipe off with a dish towel it doesnt go in
