Recently I had a little conference with a dietician, a chef and an Afghan friend about rice and this questions came up. It resulted in a very interesting conversation, at least to me.
Basmati rice has a relatively low GI of 69 value (the lowest white rice) and is probably the best white rice for diabetics, but can we get it lower.
All starchy foods like rice contain at least 3 types of starch, I will explain.
Starch is a polysaccharide which is digestible and made up of a large number of glucose molecules and will digest or be broken down to glucose (a sugar). That is right, sugar, the enemy of diabetics.
I like to think of three types of starch:-
- Amylopectin which, is easily dissolved in water and digested quickly, these are digested within 20 minutes. They are common in fresh white bread, white rice, and freshly cooked potatoes. As a result they can increase blood glucose level quickly
- Amylose which dissolves slowly in water. These are digested within 120 minutes. They are common in cooked and cooled potatoes and pasta, wholegrain bread, waxy maize starch (high in amylopectin), sorghum and legumes. They have a slower effect on blood glucose.
- Resistant starcher these take longer than 120 min to digest. They are broken down by fermentation by bacteria in the large intestine, so they act like dietary fibre. Common in beans, they do not increase blood glucose level
OK let me go back to the conversation:-.
- The Chef said that the soluble starch is important so that they can present it on the plate. It what makes the rice stand firm in those cylinder shapes that you see in restaurant! As in the photo at the top of this post.
- The dietician agreed that the soluble starch, if removed would help diabetics.
- The Afghan said that, by tradition, they soak the rice for 24 hours to make it “fluffy”. The rice is strained and fresh water added for cooking.
So let us soak rice for a few hours, we only had time for 3 hours in our discussion and I was surprised by how much “starch” was removed in this time.
I have since started soaking my rice for 24 hours and I do think it is “more fluffy”.
I have no scientific evidence that this lowers the GI of Basmati rice but it makes sense to me. If you remove some of the soluble starch and surely the GI value must fall. I would be interested in feed-back on this subject.
Other ways to lower the GI of rice.
It is claimed the recooking cooled rice increases the fibre (the resistant starch in rice), I think that it is more likely that the soluble starch has gone down the sink. But there is some science behind the claim:-
Scientists Discover a Simple Way to Cook Rice That Could Halve The Calories
Your favourite staple just got healthier.

In fact, one cup of cooked rice contains around 240 starchy calories that can be quickly converted into fat if they’re not burnt off.
But researchers in Sri Lanka have discovered a simple way of cooking the grain that dramatically cuts its calories by as much as 50 percent, and also offers some other important health benefits. And we’re never going to cook rice any other way again.
According to the 2015 study, all you need to do is get a pot of water boiling, but before adding your raw rice, you add coconut oil – about 3 percent of the weight of the rice you’re going to add.
This is a picture of the soluble starch that I obtained from 1/4 cup of recooked rice.
A dietician (not my friend) claims that adding shirataki noodles or Slendier noodles (they’re the same thing) a Japanese noodle to rice lowers its GI.
- 1 large head cauliflower
- Wash and thoroughly dry cauliflower, then remove all greens and cut into 4 even sections (see photo).
- With a box grater, use the medium-sized holes (see photo – the side commonly used to grate cheese), or a food processor with the grater attachment, to grate the cauliflower into the size of rice, leaving any large, tough stems behind.
- Transfer to a clean towel or paper towel and press to remove any excess moisture, which can make your dish soggy.
- Once you have your cauliflower rice, it’s easy to cook! Simply sauté in a large skillet over medium heat in 1 Tbsp. olive oil. Cover with a lid so the cauliflower steams and becomes more tender. Cook for a total of 5-8 minutes.
- It can also be steamed.
- Use cauliflower rice in recipes that call for rice,
