Is sugar safe in my baby's food?

The verdict

None added, and this is one of the rare areas where the strictest guidance comes from the United States rather than the UK.

The NHS statement is four words long: your baby does not need sugar. It follows with the reason: by avoiding sugary snacks and drinks, including fruit juice and other fruit drinks, you'll help prevent tooth decay. The CDC is blunter still: infants and young children have no room in their diet for added sugars, and complementary foods and drinks need to be nutrient-dense and not contain additional calories from added sugars.

Health Canada's recommendation for six to 24 months is to recommend foods prepared with little or no added salt or sugar, and to advise limiting fruit juice and sweetened beverages while encouraging offering water to satisfy thirst.

Honey counts as sugar here as well as being a botulism risk. The NHS makes both points in the same sentence.

What counts as sugar

The UK uses the term free sugars, and the definition matters because it decides what you actually have to avoid.

Free sugars are sugars added to food or drinks, plus sugars found naturally in honey, syrups such as maple, agave and golden syrup, nectars, and unsweetened fruit juices, vegetable juices, smoothies and purees. The NHS is explicit that the sugars in juice and smoothies occur naturally but still count as free sugars.

Sugar found naturally in milk, whole fruit and vegetables does not count. The NHS says we do not need to cut down on those. This is why a whole pear is fine and pear juice is not, and why plain yoghurt showing 8g of sugar per serving on the label is not a problem, because as the NHS notes, none of these are free sugars, as they all come from milk.

An apple might contain around 11g of total sugar, and none of it is free sugar unless you juice or puree it. Blending changes the classification of the same fruit.

The numbers, and where they start

The UK guideline is that free sugars should not make up more than 5% of the energy you get from food and drink each day. The age-banded limits are: no guideline limit for babies under the age of 1, no more than 10g a day at age 1, 14g at 2 to 3 years, 19g at 4 to 6, 24g at 7 to 10, and 30g for adults.

The reason there is no limit for under-ones is not permissiveness. The NHS explains it: there's no guideline limit for babies under the age of 1, but sugars should not be added to food or drinks given to babies, and the frequency and amount of sugary food and drinks should be as low as possible. In other words the limit is zero added, so there is nothing to publish a number for.

The 10g allowance at age one is about a third of an ounce, or roughly two and a half sugar cubes, and it is a UK figure. The CDC does not offer a matching allowance at all, saying instead that children younger than 24 months should not have added sugars.

Why it matters at this age

Teeth. Sugar exposure frequency, not total quantity, drives decay. The NHS advice reflects this: only offer sugary foods and drinks with meals rather than as a snack, and avoid giving them before bedtime. It applies the same logic to dried fruit, saying that raisins and other dried fruits should be given with meals rather than as a between-meal snack, because the sugar they contain can cause tooth decay.

Taste preference. The AAP's fruit juice guidance notes that juice can cause a preference for sweeter flavours instead of plain water. The window in which a child learns what food tastes like is the same window in which you are deciding what to put in front of them.

Displacement. A baby's stomach is small. Calories spent on sugar are calories not spent on iron, protein and fat, all of which are in genuinely short supply during weaning.

Bottles and trainer cups

The NHS has a specific rule here that is easy to miss: when using a bottle or trainer cup, do not put anything in it other than breast milk, formula milk or water, and do not add anything else, including sugar, cereals, baby rice or chocolate powder. Sugar in a bottle bathes the teeth for far longer than sugar in a spoon.

Health Canada makes the related point that offering older infants an open cup can help decrease constant consumption and over-exposure of the teeth to sugar-containing liquids.

What to do instead

Use fruit. Mashed banana, stewed apple, pear, mango, dates and prunes all sweeten porridge, yoghurt and baking without adding free sugars, as long as the fruit stays in the food rather than being drunk as juice.

Check labels on baby-marketed products. The CDC names flavoured yoghurts, muffins and cookies as everyday sources of added sugars, and Health Canada notes that commercial infant foods can be high in added sugar. A pouch labelled as containing only fruit can still be a concentrated free-sugar delivery system, because pureeing is what converts fruit sugar into free sugar.

Give water or unsweetened milk to drink. The NHS says fizzy drinks can damage tooth enamel so they should not be given to young children, and that it's best to offer your child water or unsweetened milk.

Where guidance differs

Under one, nobody disagrees. No added sugar, everywhere, for the same reasons.

After the first birthday, the US is stricter than the UK. The CDC says children younger than 24 months should not have added sugars, full stop. The UK allows up to 10g of free sugars a day from age 1. That is a genuine two-way split, and it runs in the opposite direction to most infant feeding disagreements.

The UK counts juice as sugar; US guidance counts juice separately. Because the UK definition of free sugars includes unsweetened fruit juice and smoothies, a glass of pure orange juice is a sugar problem under NHS advice. The CDC treats 100% juice as a distinct category from sugar-sweetened drinks, while still saying no juice before 12 months.

Canada sets a direction, not a number. Health Canada's little or no added salt or sugar language gives no gram figure at any age in the infant guidance, and pairs it with advice to limit fruit juice and sweetened beverages and offer water for thirst.
