Health Benefits of eating fish

The benefits of eating fish

Heart disease

No wonder the Government wants us all to eat more, with the Food Standards Agency recommending at least two portions a week of fresh, frozen, or tinned seafood (one of them of oily fish). The British Heart Foundation says eating oily fish can help to reduce the risk of heart disease and improve your chances of survival following a heart attack. Fish does this by lowering levels of fats called triglycerides in the blood - raised levels are associated with heart disease. Fish oils also appear to help reduce blood clotting and abnormal heart rhythms after a heart attack.

Alzheimer's

Polyunsaturated fatty acids found in many fish may prevent damage to brain cells. Eating fish can also reduce the risk of high blood pressure, which is linked with dementia. A French study of 2000 people showed that those who ate seafood at least once a week had a significantly lower risk of dementia over a seven-year period than those who didn't.

Cancer

A Swedish study of 6000 men over a 30-year period showed that those who didn't eat any fish had between double and treble the risk of developing prostate cancer, compared to those who ate moderate or large amounts. Shellfish, such as crab and lobster, also contains selenium, thought to have cancer-fighting properties.

Depression

It's been reported that fish can help to ease depression. Again, it's down to omega-3 fatty acids, which are believed to raise levels of the brain chemical serotonin.

Arthritis

Population groups that eat a lot of fish - Inuits in Greenland, for example - have low rates of inflammatory conditions such as arthritis. Studies have also shown fish oils to be useful in relieving the symptoms of rheumatoid arthritis.

Social benefits

According to research carried out in Mauritius, children given lots of fish from the age of three are less likely to have criminal records by the time they reach 23.

Skin

According to dermatologist Nicholas Perricone, author of The Perricone Prescription, a salmon-packed diet can help smooth out age lines.

Which fish to eat

• White fish like cod are a good source of low-fat protein and minerals.
• Oily fish such as sardines, pilchards, salmon and mackerel have the highest concentrations of omega-3 fatty acids.
• Crab, lobster and mussels come into the shellfish group and contain selenium, thought to have cancer-fighting properties.
