an ally against ageing.

Oleocanthal, a compound in olive oil, has been found to slow down

an anti-inflammatory and is thought to protect against heart disease
by raising levels of ‘good’ HDL cholesterol while lowering levels
of damaging LDL cholesterol.
Oleocanthal gives olive oil its peppery taste and is highest
in virgin oils. Replace regular cooking oil with good-quality olive
oil. Use an olive oil-based spread rather than butter or margarine.
Falls and fractures
could be a thing of the past if those aged 65 and over were to top
up on Vitamin D, according to new research at Harvard University.
The vitamin plays a key role in keeping bones and muscles strong,
but many people in this age bracket still suffer from low levels.
Found in eggs,
oily fish and animal liver, Vitamin D is also made beneath the skin
when it is exposed to sunshine. The research at Harvard looked at
the effect of Vitamin D supplements when given to 10,000 people
over a period of 30 years. It led to 20 per cent fewer falls and
‘One of the
main roles of Vitamin D is to help fix calcium in bone,’ says Elisabeth
Weichselbaum, nutrition scientist at the British Nutrition Foundation.
‘One of our main sources is sunlight and most of us don’t get enough.’
Include Vitamin D-rich foods such as oily fish and eggs in your
diet. In addition, Harvard researchers recommend that those over
65 take 800 to 1000 iu of Vitamin D daily as a supplement to boost
bone and muscle strength.
HEALTH: OILY FISH
acids in fish oil have been found to reduce the risk of heart disease
and heart attack and to prevent furring up of the arteries. A study
in the American Journal Of Respiratory Care, looking at more than
10,000 patients, found that a daily 2g dose of fish oil given to
the elderly prevented a decline in heart function.
with heart disease who had already suffered a heart attack, daily
fish-oil supplements reduced cardiovascular death by 30 per cent.
Japanese research published in The Lancet found that fish oil can
make statin medication more effective, reducing heart complications
by a further 20 per cent.
‘A wealth of
evidence shows fish oil can help heart health in the elderly,’ says
Weichselbaum. ‘It also plays a role in protecting against other
age-related conditions such as joint pain, immunity and cognitive
The British Nutrition Foundation advises older people to eat
oily fish such as herring, salmon, mackerel and tuna twice a week.
