Garlic
Fresh garlic contains several compounds, the most
important of which is allicin. This has been shown to protect against high
blood pressure, infections, candida, indigestion, stomach ulcers and bowel
disorders. Several studies have shown that it can reduce harmful cholesterol by
about 12 per cent, and inhibits new growth of plaque in the arteries that can
lead to heart attack or stroke. Garlic may also inhibit the growth of cancer
cells and strengthen the immune system.
Greens
Leafy dark green vegetables, such as Savoy
cabbage, kale, and spring greens, are good sources of two carotenoids which
have been shown to help prevent age-related macular degeneration and cataracts.
Greens are also a good source of easily absorbed calcium to help maintain
strong bones, and are rich in potassium, which helps protect against calcium
loss. In addition, they're a good source of vitamins C and E.
Herbs
Several herbs are strong antioxidants, even when used in
small amounts. Thyme, oregano, rosemary, sage, basil and coriander all contain
high levels of phyto-chemicals, which can help ward off heart disease and
cancers.
Nuts
Nuts are a good source of magnesium, which is vital
for energy levels. Magnesium can help keep
muscles supple and prevent aches and pains, and may also lower the risk of
osteoporosis. Almonds, Brazils and peanuts are good for helping to build or
maintain muscle mass and help protect against glaucoma, diabetes and high blood
pressure. Research in the USA has shown that just two 25g portions of fresh
nuts a week reduced death from heart disease in men by up to 47 per cent.
Oily fish
Oily fish such as salmon, herring, mackerel and
sardines are the main source of the important fats called omega-3s. Two of them
- EPA and DHA - are not found in any other foods. These fats have a variety of
benefits, including offering some protection against the decline of brain power
and diseases such as Alzheimer's and Parkinson's. They are also
anti-inflammatory, helping to minimise the pains of arthritis and rheumatism.
In addition, they can help prevent blood clots, coronary disease and strokes.
Olive oil
Although olive oil is almost 100 per
cent fat, it is rich in nutrients and compounds that can help protect against
age-related disease. It is high in monounsaturated fats, which lower levels of
harmful LDL cholesterol while protecting the levels of "good" HDL
cholesterol, and thus helps fight heart disease and stroke. Olive oil also
contains squalene and oleuropein, which are powerful antioxidants, protecting
blood cholesterol from oxidation. This antioxidant effect may also reduce the
risk of some cancers, particularly of the breast and colon. Top-quality,
cold-pressed oils contain more of the protective compounds.
Onions
The onion family, including garlic and leeks, are
good detoxifiers and are also antiseptic and antibacterial. The sulphur
compounds they contain are also linked with protection against strokes, high
blood pressure, heart disease and cancers. Just 1g of onion a day is enough to
help strengthen the bones. Onions are rich in flavonoids and potassium, which
can reduce blood pressure and keep the arteries healthy, and the onion family
may also help to keep blood sugar levels even by regulating insulin production.
Spices
Most spices are strong antioxidants and have a
variety of beneficial effects. Ginger is an anti-inflammatory and can help
ease the pain of arthritis. Chillies contain the plant chemical capsaicin,
which is a great reliever of general aches and pains, and coriander seeds can
lower blood pressure.
Soya
Soya beans contain high levels of plant oestrogens
and magnesium, both of which may help to minimise menopausal symptoms. Soya beans
are high in soluble fibre, and have also been shown to help reduce the risk of
heart disease. Soya protein helps build and maintain collagen and elastin, both
important for keeping skin in youthful condition.
Tomatoes
Tomatoes are rich in the carotenoid lycopene, which
provides some protection against cancer and heart disease. Recent trials have
found that women who eat a lot of lycopene have lower risks of ovarian or
breast cancer, while in men it helps prevent prostate cancer. Tomatoes are also
a good source of lipoic acid, which helps increase energy levels and improve
brain power in some people. Small, ripe tomatoes tend to contain the highest
levels of lycopene and cooking them helps absorption.
