Why is Mackerel Fillets in Tomato Sauce classified as a NOVA 3 product and what processing steps are involved?

It is a canned fish that undergoes cooking and heat-sterilisation before sealing; because it contains only a few whole ingredients (mackerel, tomato paste, water, oil, sugar, salt) and no industrial additives, it falls into the moderately processed NOVA 3 category rather than the ultra-processed NOVA 4 level.

How do the sugar and salt levels in this product impact a diabetic or hypertensive diet?

The 3.36 g of sugar per 100 g can raise blood glucose and should be limited by people with diabetes, while the 0.66 g of salt is moderate and may be acceptable for most hypertensive individuals but still contributes to daily sodium intake.

Is Mackerel Fillets in Tomato Sauce suitable for vegan, keto, halal, or gluten-free diets?

The product is not vegan or vegetarian because it contains fish, it is low in carbohydrates and high in fat making it keto-friendly, the fish and rapeseed oil are generally considered halal, and it contains no gluten-containing ingredients, so it fits a gluten-free diet.
