Fish is an excellent source of protein, essential omega-3 fatty acids, iodine, important vitamins and is low in saturated fat. But it can contain mercury – which can be harmful at high levels. Although mercury is present at low levels in most fish, there is no need for anyone (including pregnant and breastfeeding women) to stop eating fish altogether.
Food Standards Australia New Zealand (FSANZ) have recently updated their Mercury in Fish brochure which provides advice for consumers on safe fish consumption.
