It’s probably no big secret that eating fish is actually very healthy. We have gathered 4 facts to back this up.

1. High in essential nutrients

  • Fish is packed with many nutrients that most people lack.
  • This includes high quality protein, iodine and a variety of vitamins and minerals.
  • Fatty species are sometimes considered the healthiest. This is because fatty fish, including salmon, trout, sardines, tuna and mackerel, are rich in nutrients with higher fat content.
  • Fatty fish also boast omega-3 fatty acids, which are key for optimal body and brain function and are closely linked to reducing the risk of many diseases.

2. Can boost brain health

  • Brain function often declines with age.
  • While mild mental decline is normal, there are also serious neurodegenerative diseases such as Alzheimer’s.
  • Several observational studies show that mental decline is slower in people who eat more fish.
  • Studies also reveal that people who eat fish weekly have more grey matter – the most important functional tissue in your brain – in the parts of the brain that regulate emotions and memory.

3. Can help prevent and treat depression

  • Depression is a common mental condition.
  • It is characterised by low mood, sadness, reduced energy and loss of interest in life and activities.
  • Although not nearly as widely discussed as heart disease or obesity, depression is now one of the world’s biggest health problems.
  • Studies have shown that people who eat fish regularly are much less likely to suffer from depression.
  • A number of controlled studies also reveal that omega-3 fatty acids can fight depression and significantly increase the effectiveness of antidepressant medication.
  • Fish and omega-3 fatty acids may also help other mental conditions, such as bipolar disorder.

4. Good source of vitamin D

  • Vitamin D acts like a steroid hormone in the body – and a whopping 41.6% of the US population is deficient in it.
  • Fish and fish products are among the best dietary sources of vitamin D. Fatty fish such as salmon and herring contain the highest amounts
  • A single 4-ounce (113 gram) serving of cooked salmon is about 100% of the recommended amount
