If you've been looking at Thai rice lately, you may have come across something called RD43.
At first glance, it looks like another bag of white rice. But RD43 is a little different. It was developed with a particular goal in mind, to create a rice variety with a lower glycemic response than traditional rice varieties, while still keeping the soft texture and pleasant aroma people love about Thai rice.
So what exactly is RD43? Why was it developed? And does it actually taste different from the jasmine rice you already know?
Let's take a closer look.
What is RD43 rice?
RD43 is a Thai rice variety developed through research involving Thailand's Rice Department and researchers from Ramathibodi Hospital, Mahidol University.
The variety attracted attention because of its moderate to low glycemic index (GI) compared with some commonly eaten rice varieties.
But the interesting part is that RD43 wasn't created simply to be "healthier rice."
The goal was to develop rice that could offer a different nutritional profile while still being enjoyable as an everyday staple.
And that's important because rice isn't just a side dish in Thai food.
For many Thai meals, rice is the heart of the plate.
Whether it's eaten with a simple stir fry, grilled chicken, curry, or a spicy nam prik, the rice needs to work with everything around it.
What does "lower GI" actually mean?
You may have seen the term GI, or glycemic index, used when talking about carbohydrates.
In simple terms, GI describes how quickly carbohydrate containing foods can raise blood glucose levels compared with a reference food.
Foods with a lower GI generally cause a slower rise than foods with a higher GI.
That doesn't mean a food is automatically "healthy" just because it has a lower GI. Your overall meal, portion size, preparation, and what you eat alongside it all matter.
But for people who pay attention to the type of carbohydrates they eat, RD43 can be an interesting rice to know about.
Does RD43 taste different from jasmine rice?
This is probably the question most people have.
After all, nutritional differences don't mean much if you don't enjoy eating the rice.
RD43 is known for having a soft texture and gentle fragrance, making it suitable for everyday Thai meals.
It's not meant to replace the experience of every type of Thai rice. Instead, it offers another option for people who want to enjoy rice while paying more attention to the type they choose.
Try it with a simple Thai meal and you'll get a better idea of how it fits into your everyday cooking.
What can you eat with RD43?
Pretty much anything you'd normally serve with rice.
It's especially easy to pair with dishes that have flavorful sauces or curries because the rice provides a mild, comforting base.
Try it with:
- Thai green curry
- Stir fried basil with chicken or pork
- Grilled chicken with spicy dipping sauce
- Thai omelet
- Stir fried vegetables
- Tom yum
- Simple fried eggs and vegetables
And you don't need to make an elaborate Thai meal every time.
Sometimes, a bowl of warm rice with a fried egg and a little chili sauce is enough.
Is RD43 only for people watching their blood sugar?
Not necessarily.
RD43 has gained attention because of its glycemic characteristics, but you don't need to be following a particular diet to enjoy it.
You might simply be curious about different varieties of Thai rice, looking for an everyday rice with a different nutritional profile, or wanting to try something that has become increasingly popular in Thailand.
Think of it as another choice for your rice bowl, rather than a "special diet food."

Different brands offer RD43 rice in slightly different formats, so you may notice organic certifications, different pack sizes, and different milling or packaging choices.
For example, some options include:

If you're curious about Thai rice beyond the usual jasmine rice, RD43 is definitely an interesting variety to put on your list.
It combines something familiar, the comforting experience of eating Thai rice, with a different nutritional profile that has attracted attention in Thailand.

It's to cook it.
