Sugar and salt: the names they hide behind, and what they do

The same ingredient hides under many names. Sugar can be sucrose, glucose syrup, honey, maltitol or "fruit juice concentrate" — all of them sweeten, and most of them count the same way in the guidance below. Salt can be sodium chloride, monosodium glutamate, sodium nitrite or soy sauce — all of them add sodium, and the nutrition panel only ever shows the total as sodium. The front of the pack rarely makes any of this clear; the ingredient list and the sodium line do.

Prompted by a post by @_bonn__appetit on Instagram (26 October 2026) — a glycemic index table for common sweeteners. This page checks that table against published sources, explains the names, and adds the salt half of the story. No image from the post is used here, and none of its wording is copied.

Why this page exists

This site compares what is actually in Singapore products, page by page. This guide is the companion to those pages: it explains the words you will meet on them. Three things it is for:

This page does not score or rank anything, and it does not tell you what to eat. It explains labels. For personal dietary advice, talk to a doctor or dietitian.

Sugar — every name it goes by

All of these sweeten. What differs is what they are made of, how fast they raise blood sugar (see the glycemic index table below), and whether they count as "free sugars" in the WHO guidance (nearly all of them do — see What the guidance says). Where a name shows up on this site's own pages, the example is linked — nothing here is invented.

(a) Sugars — the "ose" family

(b) Syrups and liquid sugars

(c) "Natural" sweeteners

(d) Sugar alcohols (polyols)

Sugar alcohols are sweet, but they are not sugars and not alcohols. They are only partly absorbed, so they raise blood sugar less — and so much of them can cause bloating, gas and a laxative effect. In the EU, any food with more than 10% added polyols must carry the words "excessive consumption may produce laxative effects" (Regulation (EU) No 1169/2011). In Australia and New Zealand, warning statements apply above 10 g per 100 g for lactitol, maltitol, mannitol and xylitol, and above 25 g per 100 g for erythritol, sorbitol and isomalt. Erythritol is the best tolerated of the group.

(e) High-intensity sweeteners

These are hundreds of times sweeter than sugar, so they are used in tiny amounts and add effectively no calories. They do not raise blood sugar on their own — but read the whole list: commercial packets and blends usually contain a carrier (dextrose, maltodextrin, erythritol or lactose), and the carrier is what you are mostly eating.

Glycemic index of sweeteners — checked against published sources

What the glycemic index (GI) is: how fast a food containing carbohydrate raises blood glucose over two hours, compared with pure glucose, which scores 100. The test feeds a portion containing 50 g of available carbohydrate to healthy people after an overnight fast. Bands used in the published tables: low is 55 or below, medium is 56 to 69, high is 70 or above.

What it is not: a health score. GI measures speed, not nutrition. A low GI does not make something healthy — fructose is the clearest example: it scores low because the liver handles it, not because it is good for you, and it still counts as a free sugar. And the amount eaten matters at least as much as the number: glycemic load is GI × grams of carbohydrate per serving ÷ 100, so a small amount of a high-GI sweetener can raise blood sugar less than a large amount of a low-GI one.

About the numbers below: the starting list is the Instagram post by @_bonn__appetit (26 October 2026). Each number was checked against the international glycemic index tables (Atkinson et al. 2021, American Journal of Clinical Nutrition), the 2008 international tables, the University of Sydney GI database, or a review drawing on them (Brouns 2020, Frontiers in Nutrition). Where published sources disagree, or no reliable GI exists, the table says so — the post's number is not presented as settled. Click a column header to sort.

SweetenerGI (glucose = 100)What the number rests on
Glucose / dextrose100The reference food itself. Atkinson et al. 2021. Post said 100 — confirmed.
Maltodextrin~110Sweetener GI chart derived from the University of Sydney GI database; not listed as a standalone entry in the 2021 international tables. Higher than table sugar — it is a starch fragment, and it is the carrier in Splenda packets.
Maltose~105Same chart-derived source; not a standalone entry in the 2021 international tables.
Sucrose (white sugar)65Atkinson et al. 2021 (65–66 across tabulations; 2008 tables 65 ± 4). Post said 65 — confirmed.
Brown sugar65Same as sucrose: brown sugar is white sugar plus molasses. Post said 65 — confirmed.
Golden syrup60Brouns 2020, drawing on Atkinson/Sydney data.
High-fructose corn syrup (HFCS-55)58Brouns 2020. Not in the post's table; added because it appears on this site's pages.
Molasses55Brouns 2020 (blackstrap molasses).
Maple syrup54Brouns 2020; University of Sydney testing. Post said 55 — within a point of the published value.
Honey~50–61Varies by the honey tested: Brouns 2020 gives 50; Atkinson 2021 average of 17 honeys is 60; 2008 tables average 61. Post said 50 — the low end of the published range.
Lactose~46Atkinson et al. 2021, via Shkembi & Huppertz 2023.
Coconut sugar35 or 54 — disputedTwo published values disagree: the Philippine Food and Nutrition Research Institute measured 35; a 2014 University of Sydney test measured 54. Post said 35 — one of the two published values, not settled.
Fructose~15–25Published averages differ by test: 2008 tables 15 ± 4; 2021 average about 24–25. Post said 25 — the 2021 average. Low because the liver metabolises fructose before it reaches the blood as glucose; still a free sugar.
Galactose25Brouns 2020.
Agave syrup15University of Sydney testing, range 10–19. Low because agave is mostly fructose. Post said 15 — confirmed.
Xylitol7–13Sources vary within this range; commonly cited as 12. Post said 12 — within the published range.
Sorbitol~9Sweetener GI chart derived from the Sydney database; published lists range 4–9.
Maltitol35Powder form; maltitol syrup is higher, about 52. Chart-derived.
Isomalt2Chart-derived.
Erythritol0–1Effectively no blood-sugar rise. Post said 0 — confirmed.
Stevia (steviol glycosides)0No carbohydrate, no measurable GI. Post said 0 — confirmed.
Monk fruit0No carbohydrate, no measurable GI. Post said 0 — confirmed.
Allulose0Absorbed but not metabolised, so no blood-sugar rise. Not listed in the international GI tables — the 0 is the widely stated value, not a published GI test. Post said 0 — consistent, with that caveat.
Sucralose, aspartame, acesulfame K, saccharin0No carbohydrate in pure form. Note: commercial packets are not GI 0 — Splenda packets list dextrose and maltodextrin first.
Jaggery (gur)No standard valueNot in the international GI tables at all. The widely quoted 84 comes from a small 1987 Madras study (Uma et al.) in 18 people with type 2 diabetes: a one-hour reading of 84.4, where sucrose read 69.2 by the same method — but over the full two-hour curve that study found jaggery 87.4 and sucrose 83.9, i.e. alike. The post said 85 — that is the one-hour reading, not a standard GI value. Treat jaggery as sugar.
Date powder / date sugarNo standard valueNo standard published GI exists. Raw dates test at 42 (2008 tables); online lists for date sugar range from 20 to 68. The post said 30 — one of several conflicting figures, not verified.

Click a column header to sort lowest-to-highest, click again for highest-to-lowest. Rows with no standard value always sort last — a missing value is not zero.

How the post did, checked: of its 15 numbers, 11 check out against published sources (stevia, monk fruit, erythritol, allulose, xylitol, agave, fructose, honey, white sugar, brown sugar, glucose/dextrose), maple syrup is within a point (55 vs the published 54), and 3 need a flag — coconut sugar (two published values, 35 vs 54), jaggery (the 84/85 is a one-hour reading from a small 1987 study in people with diabetes, not a standard GI value), and date powder (no standard published GI at all; online figures range 20–68).

Salt / sodium — every name it goes by

Sodium is the part of salt that matters for blood pressure, and it arrives under many names. The nutrition panel only ever shows the total, as sodium in milligrams. To get salt: salt (g) = sodium (mg) × 2.5 ÷ 1,000 — the same conversion this site uses on every category page.

The names

Hidden salt — real numbers from this site's own pages

These are sodium figures as printed on this site's category pages, per 100 g (or per 100 ml for soy sauce). The WHO daily limit for adults is less than 2,000 mg sodium (5 g salt) a day — read each row against that.

Product (from this site)Sodium per 100 g / 100 mlSalt equivalentWhat it means
Kikkoman Naturally Brewed soy sauce6,833 mg / 100 ml17.1 gA single tablespoon (15 ml) is about 1,025 mg sodium — over half the day's limit.
Nongshim Shin Ramyun Spicy (instant noodles)1,940 mg / 100 g4.85 gNearly the whole day's sodium in 100 g of dry product.
Maggi 2-Minute Curry (instant noodles)1,680 mg / 100 g4.2 gOver four-fifths of the day's limit per 100 g.
SPAM Classic (canned luncheon meat)1,411 mg / 100 g3.53 gOver two-thirds of the day's limit per 100 g.
Indomie Mi Goreng Original (instant noodles)873 mg / 100 g2.18 gLess salty than the soup noodles above — the seasoning is in a sauce, not a salty broth.
Ma Ling Premium Pork (canned luncheon meat)760 mg / 100 g1.9 gThe lowest-sodium luncheon meat panelled on this site — still over a third of the day's limit per 100 g.
Gardenia Enriched White Bread (sandwich bread)441 mg / 100 g1.10 gBread looks mild per 100 g, but it is eaten in quantity — two slices are roughly 60 g, about 265 mg sodium.

Figures are as printed on the linked category pages (some computed from printed salt, as flagged there). They are per 100 g/ml as sold, not per serving — a pack of noodles or a tin of meat is usually more than 100 g.

What the claims on the front mean (Singapore)

Under the Health Promotion Board's Handbook on Nutrition Labelling (Singapore), these claims have fixed meanings:

What the guidance says — and what it does not

Everything in this section is population-level public-health guidance with its source named. None of it is personal medical advice.

Free sugars — WHO

The World Health Organization recommends keeping free sugars below 10% of total daily energy intake, and ideally below 5% for additional health benefits (WHO Guideline: Sugars intake for adults and children, 2015). On a 2,000-calorie diet, 10% is about 50 g of free sugars a day (about 12 teaspoons); 5% is about 25 g (about 6 teaspoons). The guidance rests on evidence linking high free-sugar intake to unhealthy weight gain and dental caries.

What "free sugars" means (WHO): all monosaccharides and disaccharides added to foods or drinks by the manufacturer, cook or consumer, plus the sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates. It does not include lactose and galactose naturally present in milk, or the sugars inside whole fruit and vegetables. So honey, maple syrup, agave, fruit juice concentrate and jaggery all count as free sugars; the lactose in plain milk does not.

Sodium and salt — WHO

The WHO recommends adults consume less than 2 g of sodium a day, equivalent to less than 5 g of salt (about one teaspoon). The guidance rests on the link between high sodium intake, raised blood pressure, and heart disease and stroke. For children the limit is lower, scaled to energy intake.

Singapore — HPB and Nutri-Grade

The Health Promotion Board recommends the same sugar limit: no more than 10% of daily energy from sugar, about 50 g on a 2,000-calorie diet.

Nutri-Grade is Singapore's mandatory front-of-pack grading for drinks, run by the Ministry of Health and HPB. A drink is graded A to D on its sugar and saturated fat per 100 ml — the grade is the worse of the two — and Grade A drinks must also contain no sweetener. Labelling is mandatory for drinks graded C and D, and advertising is banned for drinks graded D. It has applied to pre-packaged drinks since 30 December 2022 and to freshly prepared drinks since 30 December 2023. From 2028 it extends beyond drinks to pre-packed salt, sauces, seasonings, instant noodles and cooking oil.

GradeSugar per 100 mlSaturated fat per 100 ml
A1 g or less, and no sweetener0.7 g or less
BMore than 1 g, up to 5 gMore than 0.7 g, up to 1.2 g
CMore than 5 g, up to 10 gMore than 1.2 g, up to 2.8 g
DMore than 10 gMore than 2.8 g

Thresholds: HealthHub / HPB, "Make Better Drink Choices With Nutri-Grade". Nutri-Grade grades sugar and saturated fat only — it does not grade sodium, and it is not a score for the whole product.

Where Singapore stands: the average Singapore resident took in 4,000 mg of sodium a day in 2025 (National Nutrition Survey 2025, released 3 October 2026) — twice the 2,000 mg limit, and up from 3,480 mg in 2019 and 3,620 mg in 2022. 95% of residents now exceed the limit. That is about 10 g of salt a day. The same survey found daily total sugar intake fell from 60 g in 2018 to 48 g in 2025, and the share of residents within the recommended sugar limit rose from 61% to 79%. On the sodium side, 64% comes from salt, sauces and seasonings added while cooking, and another 10% from instant noodles.

Non-sugar sweeteners — WHO 2023

In 2023 the WHO issued a guideline conditionally recommending against using non-sugar sweeteners as a long-term strategy for weight control — not because approved sweeteners are declared unsafe, but because the evidence does not show a long-term benefit for weight. The recommendation does not apply to people with pre-existing diabetes. The WHO's broader advice is to reduce the sweetness of the diet overall rather than substituting one sweet taste for another.

Not medical advice. This page explains labels and population guidance. It does not tell any individual what to eat, and it does not diagnose or treat anything. If you manage diabetes, high blood pressure, kidney disease, phenylketonuria or any other condition, talk to a doctor or dietitian — and check the pack in your hand, because formulations change.

How to use this with the category pages

Three checks, on any page of this site:

  1. What comes first in the list. The first ingredient is the main one. Sugar, glucose syrup or salt in first or second place means the product is mostly that — whatever the front says.
  2. Whether any sugar or sweetener appears at all, and where. Use the names above. A sweetener near the end of a long list is a small part of the product; sugar as the second ingredient is not.
  3. The sodium per 100 g in the nutrition table. Read it against 2,000 mg a day. A noodle at 1,940 mg per 100 g and a bread at 441 mg per 100 g are different stories — and the table shows both, with salt equivalents in brackets.

Good pages to start with: soy sauce (the salt-carrier shelf, with the highest sodium numbers on the site), instant noodles (MSG, enhancers and broth sodium), sugar and sweeteners (the tabletop shelf — carriers vs sweeteners), honey and maple syrup (the "natural" sweeteners, one ingredient vs corn-syrup lookalikes), and canned luncheon meat (nitrite, phosphates and the highest-sodium tins).
