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 steak (about 130g) provides about 36.4g 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.
Tuna Steak is naturally very low in fat, with about 1.3g per portion and 0g of added fat. Only around 0.39g is saturated, well within the daily maximum for every age group.
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.
Selenium helps protect cells from damage and supports the immune system. A steak (about 130g) contains 117ug. 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 steak (about 130g) contains 23mg. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Vitamin B12 supports red blood cell formation and a healthy nervous system, and is found almost only in animal foods. A steak (about 130g) contains 3ug. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Vitamin B6 helps the body release energy from food and supports the nervous system. A steak (about 130g) contains 1.3mg. 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 steak (about 130g) contains 4ug. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Phosphorus works with calcium to build strong bones and teeth. A steak (about 130g) contains 364mg. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
No. Tuna Steak is a fresh, whole fish and a NOVA group 1 food, cooked from its natural state with nothing added, which is very different from processed meats and ready meals.
