The consumption of oil-rich fish
provides an important source of vitamins A and D. Vitamin A maintains
healthy eyes, skin and hair while vitamin D is required to help
in the formation of strong bones and teeth. In addition, oil-rich
fish such as mackerel and herring contains Omega-3 fatty acids,
a type of polyunsaturated fat that has a lowering effect on blood
cholesterol levels. Omega-3 protects the heart and circulation
and may reduce the risk of heart disease. Other health benefits
derived from oil-rich fish include the relief from symptoms of
joint inflammation such as arthritis.
Amongst the minerals present in seafood are iron, zinc, iodine
and selenium. A low intake of iron can lead to fatigue, while a
shortage of iron and zinc can also lead to a lowering of the immune
defences. Insufficient iodine in the diet can lead to impaired
growth and development and the mineral selenium is linked to immune
and anti-cancer defence.
Shellfish such as oysters, which contain noticeable levels of
the mineral zinc, has also been reputed to act as an aphrodisiac – so
eating seafood may also be excellent for your love life too! |
