RICE: THE GO-TO GRAIN 

Have you eaten rice?
English translation: “Have you eaten rice?” 

This popular greeting used throughout East Asia is a reminder that traditionally food was scarce and people were often starving. Rice saved lives, so it’s not surprising that the word for “rice”, “food” and “meal” is one and the same in Chinese—and in many other parts of East Asia, too.

 Those early farmers who planted the first seeds some 10,000 to 8,000 years ago in Southern China would be gobsmacked at the number of varieties that have evolved (more than 100,000 it is estimated) and at their colours (white, red, black), sizes, shapes, aromas, stickiness and starchiness. And at all the things we make with the grains from flour, noodles, and crackers to syrup, alcohol, oil and puffed breakfast cereals. 

In wok, pot or bowl or on a plate, rice soaks up the flavours from stocks and sauces and partners with meat, chicken, fish, seafood, tofu, vegetables, nuts, or fruit in snacks, soups, salads, sides, pilafs, paellas, risottos, desserts and more. 

WHAT TO LOOK FOR
Nutty-tasting brown rice with just the inedible hull removed is the rice with the serious nutritional wholegrain credentials. This is because it contains all parts of the grain — including the fibrous bran, the nutrient-rich germ and the starch-rich endosperm. Because of this, brown rice has more dietary fibre, antioxidants, vitamins and minerals than white rice. But it tends to be slow cooking. 

However, these days we can buy 2-minute microwave options to help get meals on the table fast. Refined, popular, palatable white rice is still an ok choice, especially when combined with lots of veg. For speedy meals rice noodles are good to have on hand. Look for lower-GI varieties. 

LOWER GI RICES - THE AMYLOSE FACTOR
The starch in raw food is stored in hard, compact granules that our bodies find hard to digest, which is why starchy foods usually need to be cooked. Water and heat expand the starch granules during cooking to different degrees; some actually burst and free the individual starch molecules (this is gelatinisation). Rice is a great grain for getting to know the starches in our foods— amylose and amylopectin. 

  • Amylose is like a string of glucose molecules that tend to line up in rows and form tight, compact clumps that are harder to gelatinise and digest. The lower GI rices have a higher proportion of amylose.
  • Amylopectin is a string of glucose molecules with lots of branching points, such as you see in some types of seaweed. Amylopectin molecules are larger and more open and the starch tends to be easier to gelatinise and digest. Higher GI rices have a higher proportion of amylopectin.
