Tinned Tuna in Sunflower Oil is canned in oil, so it keeps the fish protein and iodine but carry extra fat and often a little salt (NOVA group 3). Draining the oil lowers the calories. It is a source of selenium, vitamin B12 and niacin. 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.
Half a tin, drained (about 80g) provides about 20.0g 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.
Tinned Tuna in Sunflower Oil is naturally high in fat, at about 7.2g per portion, though most of it is unsaturated. Only around 1.2g is saturated and there is 0g of added fat.
Because tinned tuna in sunflower oil is salted, a portion carries about 0.72g 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.
Selenium helps protect cells from damage and supports the immune system. Half a tin, drained (about 80g) contains 60ug. 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. Half a tin, drained (about 80g) contains 2ug. 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. Half a tin, drained (about 80g) contains 9.6mg. 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. Half a tin, drained (about 80g) contains 168mg. Because children need less than adults, that same portion covers a bigger share of a younger child's daily target.
Vitamin E is an antioxidant that helps protect cells from damage. Half a tin, drained (about 80g) contains 2.4mg. 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.
Lightly. The fish itself is a whole food, but canning it in oil adds fat and usually a little salt, which moves the tin into NOVA group 3. Draining the oil, or choosing the version in spring water, brings it closer to plain fish.
