Smoked Mackerel is cured or smoked with added salt, which places it in NOVA group 3. The fish underneath is a whole food rich in omega-3 fats, vitamin D and vitamin B12; the main thing to watch is the salt. It is a source of vitamin B12, vitamin D and selenium. Work out the numbers for any portion and age below, then see the full breakdown.
For meat and fish the numbers that matter most are protein, saturated fat and salt. The tables below set each against age-appropriate guidance.
A fillet (about 80g) provides about 15.2g of complete protein, supplying the amino acids the body needs for growth and repair. Because children need less than adults, that portion covers a large share of a younger child's daily protein.
Smoked Mackerel is naturally high in fat, with about 20.0g per portion, and most of it is saturated (4.0g). There is 0g of added fat, but the table shows how the saturated fat compares with the daily maximum, so it is best enjoyed in smaller amounts.
Because smoked mackerel is salted, a portion carries about 1.2g of salt. Children have lower daily salt limits than adults, so it is worth checking against the guidance below.
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.
Vitamin B12 supports red blood cell formation and a healthy nervous system, and is found almost only in animal foods. A fillet (about 80g) contains 6ug. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Vitamin D helps the body absorb calcium for strong bones; oily fish is one of the few natural food sources. A fillet (about 80g) contains 6ug. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Selenium helps protect cells from damage and supports the immune system. A fillet (about 80g) contains 35ug. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Niacin (B3) helps release energy from food and keeps skin and the nervous system healthy. A fillet (about 80g) contains 7.2mg. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Lightly. The fish itself is a whole food, but curing or smoking with added salt moves it into NOVA group 3. It stays nutritious and rich in omega-3 fats, vitamin D and vitamin B12; the salt is the main thing to watch.
