Breast milk is best for your baby

The World Health Organisation recommends exclusive breastfeeding for the first six months of life. Unnecessary introduction of bottle feeding or other food and drinks will have a negative impact on breastfeeding. After six months of age, infants should receive age appropriate foods while breastfeeding continues for up to two years of age or beyond. Consult your doctor before deciding to use infant formula or if you have difficulty breastfeeding.

Every choice matters. Understand Glycemic Index (GI) to learn how you can make smarter carbohydrate choices to minimize blood glucose excursions!

Singapore is a food paradise, but the prevalence of cheap and delicious carbohydrate-rich food also makes the city-state a danger zone for people with diabetes. With so many delicious carbohydrate-rich choices available, it is hard to keep track of what we consume daily.

Every food choice you make can impact your blood sugar level -- even if it's low in sweetness. Get to know about Glycemic Index (GI) to better understand how your carbohydrate choices may impact your blood sugar.

What is GI?

The American Diabetes Association defines GI as a relative ranking of carbohydrate in foods according to how they affect blood glucose levels.

Carbohydrates with a low GI value (55 or less) are more slowly digested, absorbed and metabolized and cause a lower and slower rise in blood glucose and, therefore insulin levels. For better blood sugar control, select low or medium GI food options over high GI food items.

Do note that the GI of a food is different when eaten alone than it is when combined with other foods. Thus when eating a high GI food, you can combine it with other low GI foods to balance out the effect on blood glucose levels.

What determines GI?

1) How processed is your food?

The method of processing of a single food can greatly affect its GI and processed food tend to have a higher GI. For example, white flour (GI 69) which is refined has a higher GI than whole wheat grains (GI 42). This is because grinding breaks the protective layers surrounding the grain, thus making digestion and absorption easier. Similarly, fresh fruit juices will have a higher GI than whole fruits- orange juice has GI 46 of while orange has GI of 40. Finely ground grain is more rapidly digested than coarsely ground grain. For example, instant oats cereal porridge (GI 65) have higher GI than rolled oats porridge (GI 42) .

2) How are the carbohydrates prepared?

The cooking method can make a huge difference to the food's GI as cooking breaks down the cellular structure of a food, making it easier to digest and raise blood glucose levels. Overcooking will boost the GI of food. For example, porridge has a higher GI than plain rice (83 vs 69), soft-cooked pasta has a higher GI than al dente pasta (58 vs 43), and mashed potato has a higher GI than a whole baked potato (73 vs 60). Overcooking pasta, for instance, contributes to starch gelatinisation, which then raises the GI. High heat cooking methods like baking or frying will raise GI as compared to lower heat methods like sautéing (cooking them quickly in a bit of fat) or parboiling (partially cooking them in boiling liquid). For example, baked or deep frying potato will cause GI to increase to 83 and 70 while boiling it achieves a GI of 59.

3) Does your meal contain fat, fibers or protein?

Adding fat, fiber or protein to food can help slow carbohydrate digestion and absorption, lowering GI. For instance, instant mashed potato consumed on its own has a GI of 88 while instant mashed potato consumed with butter and cheese has a GI of 66. Similarly, keeping the potato’s skin on adds fiber and lowers GI. Baked skinless white potato has a GI of 98 to 69 and potato with skin kept on has a GI of 69.

It is however important to note that not all high fibre food are low in GI. Such is because, fibre can be classified as soluble fibre and insoluble fibre. Presence of soluble fibres, which are viscous, slows down digestion and thus, food with more soluble fibre tend to be lower in GI. Insoluble fibres on the other hand, are not viscous and do not help slow digestion. Thus, food high in insoluble fibres tends to be higher in GI.

Impact of GI on blood glucose and weight

For people with diabetes, a low-GI diet can help one better manage their blood glucose levels to minimize peaks as well as to manage hunger to support or facilitate weight-loss. Nonetheless, while GI can be a useful reference used for meal planning, it should not be the only consideration. Both the serving size of foods and the nutritional quality of the diet are just as important to consider. Here are some tips to start adopting a low-GI diet:

1) Healthier Choice Symbol

Fan of cereals? Keep your eyes peeled for the ‘Low Glycemic Index’ Healthier Choice Symbol when buying cereal-based convenience foods. In general, it is always wiser to opt for healthier choice foods as they are lower in sugar, sodium, fats or higher in whole-grains and calcium!

2) Snack smart

Instead of munching on cupcakes or chips, opt for nuts. When it comes to fresh fruit, get to know the GI of your favorites as the data may surprise you. There are some moderate in GI, other fruit can deliver a high GI load. For example, the GI of watermelon is 80 while the GI of apple is 40.

3) Keep things moderate

No matter how low the GI of your carbohydrate choice, over eating is never healthy and, moderation is still key. Refer to the ‘My Healthy Plate’ by Health Promotion Board (HPB) to learn more about the various food groups and their recommended portions. Staying close to the portion guidance will also help you moderate your blood sugar swings.

5) Select 1 low-GI item per meal

While it might be challenging to switch all your choices to low GI options at once, try to include at least one low-GI item per meal. Breakfast tends to be the easiest meal to revamp. Research has shown that what you have for breakfast will determine the trend of your blood sugar level for the rest of the day, which makes breakfast one of the most important meal of the day!

Do you know?

Common breakfast foods like sugar-coated cereals, chee cheong fun, rice dumplings, sticky rice in lotus leaf and nasi lemak have a high GI.

Make a smarter choice today by switching out to low-GI breakfasts such as soon kueh (with thin skin), multigrain chapati, rolled oats (wholegrain), multigrain/ wholemeal bread, muesli (with Healthier Choice symbol), All Bran breakfast cereal.
