A nutritionist explains the health benefits of this cured oily fish, from omega-3 fats to vitamins and minerals, plus what a healthy portion size looks like.
Once considered a luxury product, smoked salmon is now widely available all year round and has become popular in a variety of dishes. But is it really good for you, and what does a healthy portion size look like? We asked a nutritionist to take a closer look at this flavourful ingredient...
What is smoked salmon?
It's salmon that has been cured by either hot or cold smoke. Each method gives the salmon a different taste and texture.
Hot smoked salmon is typically smoked at 120-180F, allowing it to cook all the way through, compared to cold smoked salmon, which is cured in salt for up to 24 hours before being smoked at 75-85F – this is considered raw.
Nutritional profile of smoked salmon
Hot smoked salmon is high in protein with around 22g per 85g portion, but it's also high in salt, containing 1.8g per serving – 30% of the Reference Intake. Being an oily fish, hot smoked salmon is relatively high in fat. One portion contains around 7.5g unsaturated fat, which includes omega 3, and about 1.6g of saturated fat.
Cold smoked salmon is very similar nutritionally to hot-smoked salmon in that it's high in protein with 19g per 85g portion, and it's a little higher in unsaturated fat with 8.6g per portion and 1.8g of saturated fat. Because cold smoked salmon is typically cured in salt, its salt content is higher with 2.5g per serving, making it over 40% of the Reference Intake.
Both types of smoked salmon are a good source of B vitamins (needed for energy), selenium, which helps our immune system to function properly and prevents damage to our cells and tissues, and vitamin D to help regulate the levels of calcium and phosphate in the body, important for healthy bones and teeth, and may also help to support the normal function of the immune system.
What is a healthy portion size?
The NHS recommends one portion of oily fish a week, such as salmon, and this serving is 140g, which is the size of a palm-sized fillet. However, smoked salmon this would significantly increase your daily salt content as one 140g portion contains over 4g of salt, making it 68% of the recommended daily allowance. Therefore, it would be advisable to have one palm-sized portion of smoked salmon a week, hot or cold, which is about 85g and contains 2.5g of salt (42%).
How to buy the healthiest smoked salmon
Whether you're buying hot or cold smoked salmon, check for any added ingredients, such as extra salt or sugar for flavour. The smoking process naturally adds plenty of flavour, so the healthier option is to buy smoked salmon with no added extras.
Wild salmon is less widely available and is typically more expensive. Nutritionally, there isn't much difference between the two, so make your decision based on your flavour preference and value.
There are also different types of salmon to consider, and each one carries a slightly different fat content, but the taste will come down to personal preference.
Should I worry about the mercury levels in smoked salmon?
The NHS advises that the general population eat no more than four portions of oily fish, such as salmon, per week. A portion is around 140g.
Women who are planning to conceive, are pregnant or breastfeeding are advised to eat no more than two portions of oily fish per week, as mercury can affect the future development of babies in the womb.
