What "High in Protein" Actually Means on a Singapore Snack Label

Walk down any snack aisle in Singapore and you'll see it everywhere: high in protein. On bars, on chips, on biscuits, on things that were, until quite recently, just biscuits.

Here's the part most shoppers don't know. In Singapore, that phrase isn't marketing fluff — it's a regulated nutrition claim with a specific legal threshold. But the threshold is not what almost anyone assumes. It has nothing to do with how many grams of protein are in the packet.

The rule isn't about grams. It's about percentage of calories.

According to the Health Promotion Board's Guide to Nutrition Labelling for Food Products, a protein claim in Singapore has to clear two conditions — and the second one is the interesting one:

"Source of Protein" / "Contains Protein"

  • The recommended daily quantity of the food must provide at least 10g of protein, and
  • Protein must contribute at least 12% of the food's calorie yield.

"High in Protein" / "Rich in Protein" / "Good Source of Protein" / "Excellent Source of Protein"

  • The recommended daily quantity must still provide at least 10g of protein, and
  • Protein must contribute at least 20% of the food's calorie yield.

Read that second condition again, because it quietly reframes the whole shelf. A snack doesn't qualify as high-protein by having a lot of protein. It qualifies by having a lot of protein relative to everything else in it. Load a bar with sugar, oil and syrup and you push its calorie count up — which pushes the protein percentage down, and can disqualify the claim even though the grams look impressive on the front of pack.

The 10-second test you can run in the aisle

Protein supplies about 4 kilocalories per gram. So you can check any claim yourself with the Nutrition Information Panel and a bit of mental arithmetic:

(grams of protein × 4) ÷ total kcal

If that lands at 0.20 or above, the food is in genuinely high-protein territory. Some quick anchors:

  • A 100 kcal serving needs about 5g of protein to hit 20%.
  • A 200 kcal serving needs about 10g.
  • A 300 kcal serving needs about 15g.

This is why a 250 kcal bar with 8g of protein — which sounds respectable — is only around 13% protein by calories. It would fall short of "high in protein" in Singapore, even though 8g is not a trivial amount of protein.

The flip side is also worth knowing: a lighter snack can clear 20% comfortably on relatively few grams. That's a real advantage if you're snacking between meals rather than trying to hit a training target.

What a protein claim does guarantee you

One useful side effect. Under Singapore's Food Regulations, a packaged product carrying any health or nutrition claim must also carry a Nutrition Information Panel, declaring energy, protein, fat, carbohydrate and any nutrient the claim refers to.

So the presence of a protein claim means you're entitled to the numbers to check it. If a pack shouts about protein but gives you no panel to verify it, that itself is a red flag.

Worth knowing too: HPB doesn't pre-approve these claims. Companies self-assess against the published criteria, and compliance is checked afterwards through post-market surveillance. The rules are real, but the checking happens after the product is already on the shelf — which is a decent argument for doing the arithmetic yourself.

What protein claims are not allowed to say

Singapore's Guide to Food Labelling and Advertisements from the Singapore Food Agency sets out claims that are prohibited outright — a food label can't imply that the product has therapeutic action, or that it will prevent, alleviate or cure a disease.

HPB's approved list does permit some modest function claims for protein, such as "protein helps in tissue building and growth" and "protein provides the essential amino acids needed to aid in the building and maintenance of body tissues". Notice how narrow those are. They're about tissue maintenance — not fat loss, not appetite control, not workout recovery.

That gap gets stretched constantly. A 2025 analysis of 102 protein products sold in the EU, reported by NutraIngredients, found that 43.8% carried health claims not authorised by the European Food Safety Authority — most commonly claims about post-workout recovery. Only six of the 102 products were fully compliant. Different jurisdiction, same commercial pressure.

And it's worth being honest about the science here rather than overselling it. Food regulation expert Luca Bucchini, quoted in that piece, made a fair point in the other direction: some unauthorised claims do have credible evidence behind them, even where regulators haven't reached consensus. "Not an approved claim" isn't identical to "not true". It just means you shouldn't treat the packet as your evidence.

Two more label words worth decoding

While you're there: "low protein" means under 5% of calories from protein, and "reduced protein" means at least 25% less than a reference food. "Reduced" claims are always relative — reduced compared to what is the question the front of pack rarely answers.

Separately, don't confuse a protein claim with the Healthier Choice Symbol. HCS is a voluntary front-of-pack scheme that flags products as healthier than others in the same category. It's a comparison within a shelf, not a verdict on the food.

The short version

"High in protein" in Singapore means protein is carrying at least 20% of the food's calories, with at least 10g in a day's recommended serving. It's a ratio, not a headline number. Multiply protein grams by four, divide by calories, and you'll know in about ten seconds whether the front of the packet is telling you something meaningful — or just something loud.

Where we come in

We built HexaCrunch around exactly this ratio problem. Our crackers are baked brown-rice crackers made with cricket protein — a protein source that lets us lift the protein share of the calories without stacking on oil or sugar to make it taste good. We publish the full panel on every pack precisely so you can run the maths above on us.

If you'd like to try before you commit to a flavour, the Try-All 3-Pack is the easiest place to start.
