25 grams. That’s the maximum WHO recommends for added sugar per day for adults — roughly six teaspoons.
Actual consumption in Vietnam is considerably higher, especially in urban areas, where sweetened drinks and processed foods have become part of everyday routines. The problem isn’t that people are eating a lot of obviously sweet food. It’s that most of that sugar comes from things few people think of when the word “sweet” comes up.
The Real Numbers: Where the Sugar Comes From
Food consumption surveys suggest urban Vietnamese adults consume an average of 40 to 60g of total sugar per day, of which added sugar (not counting naturally occurring sugar in whole fruit and dairy) accounts for approximately 30 to 45g.
Breakdown by common sources:
| Source | Estimated sugar per serving | Notes |
|---|---|---|
| Cà phê sữa đá, café (regular sweet) | 28 to 35g | From condensed milk (~3 tbsp) |
| Milk tea, medium, 50% sugar | 20 to 30g | Varies by type and toppings |
| Canned soft drink 330ml | 33 to 36g | Fixed by formula |
| Fruit smoothie with added sugar | 15 to 25g | Depends on added sweetener |
| Small sweet pastry / biscuits | 10 to 18g | Typically 2 to 3 pieces |
| White rice (200g) | 0g added sugar | Natural carbohydrate, not added sugar |
Estimates based on common product formulations available in the Vietnamese market. Variance ±20% depending on specific recipe and preparation.
Why the Number Is Usually Underestimated
Drinks don’t get counted as food. A morning cà phê sữa đá and an afternoon milk tea together already deliver 50 to 65g of sugar — more than double the WHO limit — without eating a single sweet food item.
Hidden sugar in savoury dishes. Soy sauce, hoisin sauce, ketchup, oyster sauce, braised meats, dipping sauces — almost all contain sugar. A standard Vietnamese home meal can include an additional 5 to 10g of sugar from condiments and braising liquid, unnoticed.
“Natural” doesn’t mean low in sugar. Dried fruit (raisins, dried jackfruit, banana chips), 100% fruit juice, honey, coconut sugar — all carry significant sugar. Honey contains around 17g of sugar per tablespoon. A small 200ml carton of 100% orange juice can contain 20g of sugar.
Comparison with Recommendations
| Reference | Level (g/day) | Source |
|---|---|---|
| Maximum recommended | 25g | WHO (2015) |
| Ideal target | under 12g | WHO (optimal level) |
| Estimated urban Vietnam average | 30 to 45g | Based on food consumption surveys |
The gap between actual consumption and the recommendation is not because Vietnamese people eat more candy or pastries than other populations. Most of it comes from drink culture: milk tea, coffee with condensed milk, soft drinks, and the widespread use of sweetened condensed milk in traditional beverages.
When Sugar Actually Becomes a Problem
Not everyone needs to treat this number with the same level of concern.
More relevant for people who: are managing body weight, have a history of insulin resistance or diabetes, are monitoring skin condition (high sugar intake has been associated with oily skin and acne in some individuals), or notice persistent fatigue after sweet meals.
Less critical for people who: are highly physically active, have no related health concerns, and whose overall daily calorie intake is within a balanced range.
The absolute number (25g or 30g) matters less than the overall picture of the diet.
How to Check Your Own Sugar Intake in One Day
No complex app needed. Just:
Step 1: List every sugary drink consumed yesterday (coffee, tea, soft drinks, smoothies). This typically accounts for 60 to 70% of total added sugar.
Step 2: Check the label of the three packaged foods used most often. Find the “Total sugars” line.
Step 3: Add it up. If the total from drinks alone already exceeds 25g, everything else in the day is adding on top of that.
Frequently Asked Questions
Does the sugar in rice count toward the 25g limit?
No. The WHO’s 25g recommendation applies to added sugars and free sugars, not to naturally occurring starch in rice, noodles, or potatoes. However, carbohydrates from rice still affect blood sugar through a different mechanism.
Does fruit sugar count?
Sugar in whole fruit (with the fibre intact) is not the added sugar WHO is concerned about. However, fruit juice (with fibre removed) and dried fruit are classified as free sugars and are worth paying attention to.
Is honey or coconut sugar better than white sugar?
In terms of blood sugar impact and total sugar content, the three are broadly equivalent. Honey and coconut sugar contain small amounts of trace minerals, but not in quantities that make a meaningful nutritional difference at typical serving sizes. Total sugar intake matters more than the source.
Is staying under 25g per day actually realistic?
For someone who drinks cà phê sữa đá daily: difficult without changing the drink. For someone who switches to black coffee or coffee with unsweetened fresh milk, the target is achievable without changing much else.
