Advantages of Eating Fish Foods

 

It is suggested that we should eat more fish. This is because fish is low in fat, high in protein and an excellent source of omega 3 fatty acids. Researchers worldwide have discovered that eating fish regularly - one or two serves weekly - may reduce the risk of diseases ranging from childhood asthma to prostate cancer. Healthy ways to enjoy fish include baked, poached, grilled and steamed.

Health benefits of eating fish

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

Asthma - children who eat fish may be less likely to develop asthma.
Brain and eyes - fish rich in omega 3 fatty acids can contribute to the health of brain tissue and the retina (the back of the eye).
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.
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.
Dementia - elderly people who eat fish or seafood at least once a week may have a lower risk of developing dementia, including Alzheimer's disease.
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).
Diabetes - fish may help people with diabetes manage their blood sugar levels.
Diabetes - fish may help people with diabetes manage their blood sugar levels.
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.

Foods rich in omega 3 fatty acids

The recommended daily amount of omega 3 fatty acids from fish is 200-600mg and from plants it is 1-2g.

The following are approximate amounts of omega 3 fatty acids per 60g serve of varieties of fish:

Salmon (fresh Atlantic) 1,200mg
Smoked salmon 1,000mg
Canned salmon 500mg
Sardines 1,500mg
Trout (fresh rainbow) 350mg
Gemfish 300mg
Blue-eye, shark (flake), salmon, squid 250mg
Scallop or calamari 200mg
Sea mullet, abalone 170mg
Canned tuna 145mg
Orange roughy or sea perch 7mg.

The following are approximate amounts of omega 3 fatty acids per 60g serve of other foods:

Two slices of fish oil enriched white bread 27mg
Lean beef or lamb 40mg
One fish oil enriched egg 200mg
Fish oil enriched margarine (10g) 60mg
One regular egg 40mg.
The best source of omega 3 fatty acids is fish, rather than fish oil capsules.

Fish oil reduces risk of heart disease

Hundreds of studies have been done on fish or fish oils and their role in the prevention or treatment of heart disease. A review recommends fish or fish oil supplements to prevent heart attacks, particularly in people with vascular disease. How omega-3 fats reduce heart disease is not known, but they are known to lower blood triglycerides and blood pressure, prevent clotting, are anti-inflammatory and reduce abnormal heart rhythms.

Types of fish cuts

The types of fish cuts available include:
Fillet - the boneless flank of the fish.
Dressed - with head and fins (entrails, scales and gills are removed).
Steak - cross-sections taken from a dressed fish.
Gutted - whole fish with entrails removed.
