health benefits of fish

Filled under: ,

Researchers worldwide have discovered that eating fish regularly - one or two servings weekly - may reduce the risk of diseases ranging from childhood asthma to prostate cancer. Fish is low in fat, high in protein and an excellent source of omega 3 fatty acids.

Regular consumption of fish can reduce the risk of various diseases and disorders. Selected research findings indicate the following:

Brain and eyes
Fish rich in omega 3 fatty acids can contribute to the health of brain tissue and the retina (the light sensitive tissue lining the inner surface of the eye).

Cardiovascular disease
Eating fish every week reduces the risk of heart disease and stroke by reducing blood clots and inflammation, improving blood vessel elasticity, lowering blood pressure, lowering blood fats and boosting 'good' cholesterol.

Asthma
Children who eat fish may be less likely to develop asthma.

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.

Depression
People who regularly eat fish have a lower incidence of depression (depression is linked to low levels of omega 3 fatty acids in the brain).

Cancer
The omega 3 fatty acids in fish may reduce the risk of many types of cancers by 30 to 50 per cent, especially of the oral cavity, oesophagus, colon, breast, ovary and prostate.

Diabetes
Fish may help people with diabetes manage their blood sugar levels.

Eyesight
Breastfed babies of mothers who eat fish have better eyesight, perhaps due to the omega 3 fatty acids transmitted in breast milk.

Inflammatory conditions
Regular fish consumption may relieve the symptoms of rheumatoid arthritis, psoriasis and autoimmune disease.

Prematurity
eating fish during pregnancy may help reduce the risk of delivering a premature baby.

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. Healthy ways to enjoy fish include baked, poached, grilled and steamed forms.
