Jerusalem Artichoke is a fresh, whole vegetable and, as a NOVA group 1 food, delivers naturally occurring energy and nutrients with no added sugar, salt or additives. It is a source of iron, potassium and thiamin. One portion counts as one of your five a day. Work out the numbers for any portion and age below, then see the full macro and micronutrient breakdown.
The tables below put each macronutrient against age-appropriate guidance, because what matters for a 4 year old is very different from an adult.
About 2 artichokes (80g) contains about 7.7g of sugar, and it is all natural (intrinsic) sugar that comes packaged with fibre and water. It has 0g of added or free sugar, so it does not count toward the daily free sugar limit the NHS sets. The table shows those limits by age; Jerusalem Artichoke contributes nothing to them.
Jerusalem Artichoke is naturally very low in fat, with about 0.01g per portion and 0g of added fat. Only around 0.0g is saturated, well within the daily maximum for every age group.
Fibre supports healthy digestion, and most people in the UK do not get enough. A portion provides about 1.28g. Because children need less fibre than adults, that same portion covers a bigger share of a younger child's target.
There is about 13.6g of carbohydrate per portion. There is no single daily target, but roughly half of daily energy should come from carbohydrate; the reference values below are based on that.
Percentages are share of the daily Nutrient Reference Value (NRV). Under UK and EU rules a food is a source of a nutrient at 15% NRV per 100g and high in it at 30%.
These tables show how the nutrients compare to daily needs across different ages, using UK Reference Nutrient Intakes (RNIs). This differs from the source of and high in labels above, which use the single adult figure (NRV) set for food packaging. Children's needs are lower, so a portion goes further.
Iron is needed to make red blood cells that carry oxygen around the body. About 2 artichokes (80g) contains 2.72mg. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target. Girls aged 11 and over and women need more iron (14.8mg) because of menstrual losses.
Potassium helps control blood pressure and supports normal muscle and nerve function. About 2 artichokes (80g) contains 343mg. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Thiamin (B1) helps the body release energy from carbohydrate. About 2 artichokes (80g) contains 0.16mg. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Copper helps the body make red blood cells and supports the immune system. About 2 artichokes (80g) contains 0.11mg. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target. These figures use safe intake levels, as no formal UK RNI is set.
No. Jerusalem Artichoke is a NOVA group 1 whole food, the least processed category, eaten in its natural state with nothing added. The sugars are intrinsic, packaged with fibre and water, which is why whole vegetables behave very differently in the body from foods made with free sugars.
