Sushi can be a healthy choice, but it depends on the variety you order. Oily fish such as salmon and tuna contain omega-3, which is an essential fatty acid. The World Health Organisation recommends eating 1-2 portions of oily fish a week, so sushi can be a delicious way to reach these targets.
Commonly used vegetables include cucumber, aubergine and avocado. Aubergines are a good source of fibre, vitamins B1 and B6, and potassium. Avocados are an excellent source of monounsaturated fat and vitamin E.
Seaweed is also used in sushi, both as dried sheets used to wrap around the rice (nori) or in salads (wakame). Seaweed is high in fibre and protein as well as being a good source of minerals including iodine, iron, zinc and vitamin B12.
