Herring is a healthy, affordable and delicious type of oily fish that is packed with nutrients.

This small silver-colored fish primarily lives near coastal regions of the Atlantic and Pacific ocean.

Herring is particularly beneficial for its omega-3 content, and it offers one of the most concentrated sources of the fatty acid.

In this article, we will examine the potential health benefits of herring and take a look at its full nutrition profile.

1) Herring Is Very High In Omega-3 Fatty Acids

Omega-3 fatty acids have anti-inflammatory properties, and oily fish consumption has been shown to (1, 2, 3);

  • Lower triglyceride levels
  • Decrease levels of VLDL (very low-density lipoprotein)
  • Increase HDL levels

All of these changes are thought to lower the risk of cardiovascular events (4, 5, 6).

The Dietary Guidelines for Americans 2015-2020 recommend at least 250 mg of EPA/DHA omega-3 fatty acids per day (7).

EPA and DHA are the most bioavailable form of omega-3, and they are found primarily in seafood such as oily fish.

However, the average consumption of EPA and DHA omega-3 in the United States is less than one-third of this amount (8).

On the positive side, herring is an excellent source of omega-3, and a standard herring fillet provides 3181 mg of omega-3 (9).

For another omega-3 rich fish, see this guide to anchovies.

Key Point: Herring contains significant amounts of omega-3 fatty acids.

2) Herring Contains Various Antioxidants

Most people think of things like green tea and red wine when they hear the word “antioxidants.”

However, two of the most potent antioxidants are essential nutrients, namely vitamin E and selenium.

Both of these nutrients play an important role in the immune system, and they help to minimize the damage caused by free radicals to body tissues (10, 11).

Per 184 g fillet, herring provides 96% and 10% of the RDI for selenium and vitamin E respectively (9).

Key Point: Herring is a good source of selenium and vitamin E, both of which have antioxidant properties.

3) Herring Provides a Substantial Amount of Vitamin D

It is common knowledge that (safe) sun exposure is the best source of vitamin D.

However, there are also some excellent food sources of vitamin D3, and herring is among the very best.

To illustrate this; just one fillet of herring provides 307 IU of vitamin D, which is equivalent to 76.8% of the RDI (9).

Unfortunately, a lot of people struggle to obtain sufficient levels of vitamin D.

For example, 39.4% of the UK population, which has a cold and dark winter, has vitamin D deficiency during the winter months (10).

Additionally, vitamin D is prevalent around the world for people of all ages (11).

For these reasons, herring could be an excellent choice of food for those who live in parts of the world with limited sunlight hours.

Vitamin D has numerous vital roles in the human body, and research suggests that it may lower the risk of serious diseases such as cancer and cardiovascular disease (12).

Key Point: Herring provides an extremely high amount of vitamin D.

4) Rich In Protein

Herring is protein-rich, and a regular 184-gram fillet offers 33 grams of high-quality protein (9).

As a complete source of protein, herring provides all the essential amino acids in sufficient amounts.

Additionally, since herring only contains around 291 calories per fillet, it is a relatively low-calorie and thereby protein-dense food.

Key Point: Herring offers a good source of protein.

5) Herring Has Low Levels of Mercury

A Herring Fish.

Although seafood as a food group is very nutritious, some popular species (such as swordfish) contain large amounts of mercury.

Mercury is a toxic heavy metal that can cause a wide range of adverse health effects in the body, and it is toxic to the major organs (13).

Fortunately, another benefit of herring is that it is one of the cleanest ocean fish, and it contains minimal amounts of mercury.

For example, research from the FDA demonstrates that herring has a mean mercury concentration (PPM) of 0.078 (14).

Compared to fish species such as shark (0.979 PPM), swordfish (0.995 PPM) and albacore tuna (0.358 PPM), this is very low.

Key Point: Herring is one of the cleanest seafood sources and it contains very little mercury.

6) May Increase Nitric Oxide Production (Which Lowers Blood Pressure)

One recent study suggests that herring has the effect of increasing nitric oxide production (15).

This randomized trial randomly assigned male participants to either a “herring diet” of five meals per week of herring for four weeks or to a “chicken diet” with the same schedule.

The men on the herring diet showed an increase of nitric oxide in the blood compared to men on the chicken diet. Higher blood concentrations of nitric oxide tend to lower blood pressure (16, 17).

However, since this was only a small study (15 participants), further research is necessary.

Unfortunately, herring is not one of the more popular areas of nutrition research, and there are little further studies in this area.

Key Point: Herring may raise blood levels of nitric oxide, possibly via its unique amino acid profile.

7) Incredibly Rich In Vitamin B12

Herring contains large concentrations of vitamin B12.

Per 184-gram fillet, herring provides 419% of the RDI for the vitamin (9).

In addition, herring contains a good amount of the other B vitamins, all of which play an essential role in energy metabolism (18).

Vitamin B12 is one of the world’s most common nutrient deficiencies, particularly in older adults.

On this note, research shows that up to 38% of older adults may exhibit mild signs of deficiency (19).

Since just one fillet of herring contains so much vitamin B12, it is an excellent dietary option for those at risk of deficiency.

Key Point: Herring is a significant source of vitamin B12.

8) Herring Is Very Nutrient-Dense

Herring contains large concentrations of nutrients for very few calories, which makes it a very nutrient-dense food.

For example, herring supplies every essential nutrient (in varying proportions).

This oily fish also offers many multiples of the RDI for vitamin B12 and vitamin D per 100 grams – all for only 158 calories (9).

When you consider that herring is also an excellent source of omega-3, it is challenging to get this combination of nutrients from other food.

In short; herring is a great source of nutrition.

Key Point: Herring provides a varied and concentrated source of essential vitamins and minerals.

9) Herring Is Affordable, and It Tastes Great

Lastly, while not technically a “health benefit,” herring also offers excellent value-for-money.

It is very cheap and easily affordable, and you can buy it in numerous different varieties whether fresh, pickled, smoked, or canned.

Herring is also a tasty fish; it is very flavorful, and it has a soft, tender flesh thanks to its high concentration of fat.

Food being healthy and nutritious isn’t always enough if nobody wants to eat it, but herring is an enjoyable food to eat.

Key Point: Herring is cheap and affordable, and it tastes great.
