Curly Questions

What’s the GI and GL of raw wheat bran. We have a brand here in the UK called Jordans Wheat Bran which is quite coarse.
If your raw wheat bran is the same as ours here in Australia, then this is a very low carbohydrate product that can’t have a GI or GL (it’s too low to test). This means it won't cause any rise in blood glucose levels. In fact, studies show that it will have a ‘second meal’ effect, which means it will lower the blood glucose response to the next meal.

Are products containing sucralose in the high GI range? If so, are Swerve, stevia, Truvia, or xylitol acceptable sugar substitutes?
By sucralose we assume you mean Splenda. Sucralose is a non nutritive sweetener and is hundreds of times sweeter than table sugar (sucrose), has no effect on blood glucose levels and does not provide any calories because it is not absorbed into the body. It contains no carbohydrate and does not have a GI. There's an excellent chapter on sugar and sweeteners in The New Glucose Revolution for Diabetes (The Diabetes and Pre-diabetes Handbook in Australia) by Prof Jennie Brand Miller et al PLUS a great ‘What sweetener is that?’ summary table. The information there should answer many of your questions about sugars and sweeteners of all kinds.
