The waiter at the mamak doesn't wait long. "Minum apa, boss?" and before you think, "teh tarik satu" is already out of your mouth. Habit orders for you. If your doctor has mentioned your blood sugar, those three seconds are where better drinks for diabetes start.
In our earlier look at sugar in Malaysian drinks, we found that a mamak kopi or a glass of sirap bandung can carry five or six teaspoons of sugar, and that drinks supply close to half of the sugar Malaysian adults take in. This guide is the practical follow-up: what to ask for instead, how to step down without hating every sip, and which "healthy" drinks for diabetes are not as innocent as they look.
Good drinks for diabetes have one thing in common: little or no added sugar, so they don't push your glucose up on top of the meal you're eating. Choosing drinks for diabetes rules out less than you might think. You can still sit at the kopitiam with friends; you just order differently.
The fresh drinks are where most of the change has to happen. A policy study reported in a March 2026 analysis of the sugar tax found that Malaysian adults have about 7.3 self-prepared sweet drinks a week, compared with 4.6 bottled or packet ones, and that stall-made drinks such as teh tarik and Milo largely escape the tax. No tax will pick your drinks for diabetes for you. That choice happens at the counter.
The mamak order guide: drinks for diabetes, translated
"Kosong" means no sugar. "O" means no milk. "C" means evaporated milk instead of condensed milk. Put those together and you have most of the vocabulary you need. A national "Jom Kosong" campaign has even made sugar-free drinks 20 sen cheaper at participating mamak, Indian and tom yam restaurants.
| Instead of | Try | Why it helps |
|---|---|---|
| Teh tarik | Teh O kosong, or teh C kosong if you want milk | No condensed milk, no added sugar |
| Kopi susu / kopi peng | Kopi O kosong, or kopi C kosong | Keeps the coffee, drops the sweet milk |
| Milo ais | A small Milo kosong, as an occasional treat | The powder is still sweet, but you skip the condensed milk |
| Sirap bandung / sirap ais | Limau suam kosong or air suam | Sour and refreshing without the rose syrup |
| Barley ais | Barley kosong | Same drink, no syrup |
| Packet soya with sugar | Unsweetened soya | Keeps the protein, skips the added sugar |
| Bubble tea, normal sugar | 0% sugar, fewer or no pearls, smallest size | The syrup and sweetened pearls carry most of the load |
One honest warning: teh tarik is the hardest drink to make kosong. Restaurant staff interviewed for the same Jom Kosong report explained that the "pull" depends on condensed milk, and evaporated milk doesn't froth the same way. If teh tarik is your favourite, keep it as a small weekend treat and make teh C kosong one of your weekday drinks for diabetes.

How to step down to better drinks for diabetes without suffering
Going from teh tarik to teh O kosong overnight usually fails. The first sip tastes bitter and you're back to your old order by Thursday. A slower plan works better because your taste buds really do adjust. In a small study where people cut their sugar intake for three months, they rated sweet puddings about 40% sweeter than people who hadn't cut back. The effect was weaker for drinks, but it was there.
Week 1: kurang manis everything
Keep your usual drinks, but add "kurang manis" to every order. Most stalls will halve the sugar or condensed milk without fuss.
Week 2: cut one glass a day
If you have three sweet drinks a day, make one of them air suam or Chinese tea. The easiest one to replace is usually the drink you have out of habit, not the one you enjoy.
Week 3: switch to C kosong
Move your milky drinks to teh C kosong or kopi C kosong. Evaporated milk still gives body and creaminess, minus the sugar.
Week 4: O kosong as the default
By now teh O kosong or kopi O kosong won't taste as harsh. Make it the default and keep one sweet drink a week as something you look forward to.
Check how it's going with your meter if you have one. Test two hours after the same breakfast in week 1 and week 4. Seeing the difference in your own numbers is the best motivation to stick with drinks for diabetes that suit you.
"Healthy" drinks for diabetes that aren't so healthy
Some drinks sound like obvious drinks for diabetes but bring their own sugar. The Ministry of Health's food composition database gives a useful reality check.
- Fruit juice. Even freshly squeezed orange juice has about 7 g of sugar per 100 ml, roughly 18 g in a 250 ml glass, with none of the fibre of the whole fruit. The NHS advises keeping fruit juice and smoothies to 150 ml a day in total. Eat the orange instead.
- 3-in-1 sachets. An instant tea mix is about 74% sugar, so one sachet adds close to 11 g before you count the rest of your day. Plain tea bags or black coffee powder with a splash of fresh milk are easy swaps for the office pantry.
- Isotonic drinks. These were made to replace salt and fluid after long, sweaty exercise. At about 6.7 g of sugar per 100 ml, a 500 ml bottle would carry over 30 g. For a desk job or a short walk, plain water does the job.
- "Less sugar" packet drinks. Packet soya with regular added sugar comes in at about 10 g per 200 ml. A "healthier choice" logo only means the drink is under a set sugar line, not that it is sugar-free. Read the per 100 ml figure and multiply by the pack size.
- Bubble tea at "normal" sugar. The database lists pearl milk tea at about 9.6 g per 100 ml. A 500 ml cup works out to almost 48 g. Ask for 0% sugar and less pearls.
The easy drinks for diabetes: water, plain tea and coffee
The simplest drinks for diabetes are the ones you already know. Plain water and air suam come first on any list of drinks for diabetes.
Chinese tea, green tea, teh O kosong and kopi O kosong have almost no sugar of their own. A squeeze of lime, a few slices of cucumber or a sprig of mint can make water less boring. Plain fresh milk and unsweetened soya are reasonable drinks for diabetes in sensible amounts too; milk has its own natural sugar, so count a big glass as part of your meal.
Some people find their readings move after strong coffee even without sugar. If you notice that pattern on your meter, mention it at your next clinic visit rather than guessing.
A safety note: if you use insulin or tablets that can cause low blood sugar, sweet drinks may be part of the hypo plan your doctor gave you. Cutting sweet drinks in daily life doesn't mean throwing out that emergency supply.
What about alcohol?
Keep this short and careful. Diabetes UK explains that alcohol makes it harder for your body to recover when blood sugar is falling, so people on insulin or sulphonylureas face a higher hypo risk that can last for hours afterwards. Never drink on an empty stomach, avoid sweet mixers, and ask your doctor whether alcohol is safe with your medicines before treating it as one of your drinks for diabetes.
Switched your drinks for diabetes but readings still high?
Many of our customers tell us they moved to kosong drinks for diabetes months ago, yet their post-meal readings still don't come down as much as they hoped. That's when some add extra support alongside their routine.
Regena Bitter Melon Plus is Malaysia's only MAL-certified blood sugar capsule, registered with the Ministry of Health (KKM). Each capsule combines three natural ingredients:
- Care300® mango extract — a Swiss patented ingredient with a clinical study published in Planta Medica, supporting insulin sensitivity and helping improve post-meal blood sugar
- Japanese bitter melon peptide — helps slow down sugar absorption
- Antioxidant black seed oil — supports the body's antioxidant defence
Take one capsule after breakfast and one after dinner. The compact bottle slips into your bag, so it goes wherever you makan.
Regena works together with the habits above — not instead of them, and not instead of the treatment your doctor prescribes.
The bottom line
The best drinks for diabetes in Malaysia are already on every mamak menu: teh O kosong, kopi C kosong, barley kosong, limau suam and plain water. You don't need to give up the kopitiam; you need a new order and a few weeks for your taste buds to catch up. Start with kurang manis this week, watch the "healthy" traps like juice and isotonic drinks, and let your meter show you what changes.
