Eggs are the new superfood

Eggs have long been demonised as being bad for the heart. Yet new research suggests
that this is not only untrue, but that eggs could even be considered a 'superfood'.

Eggs could actually protect against heart disease, breast cancer and eye problems and
even help you to lose weight.

For years people assumed eggs were bad for cholesterol levels. But a review just
published in the British Nutrition Foundation’s Nutrition Bulletin found they ‘have no
clinically significant impact’ on heart disease or cholesterol levels.

Dr Bruce Griffin of the University of Surrey’s school of biomedical and molecular
science analysed 30 egg studies, among them one from Harvard University which showed
people who consumed one or more eggs a day were at no more risk of suffering from
cardiovascular disease than non-egg eaters.

Egg yolks contain cholesterol, but nutritionists now know it is the saturated fats in
food, not dietary cholesterol, that raises blood cholesterol levels, a risk factor for
heart attacks.

‘To view eggs solely in terms of their dietary cholesterol content is to ignore the
potential benefits of eggs on coronary risk factors, including obesity and diabetes,’
Dr Griffin says.

Eggs are actually good for you. ‘They are rich in nutrients,’ says Joanne Lunn,
nutrition scientist at the British Nutrition Foundation. One egg provides 13 essential
nutrients, all in the yolk (egg whites contain albumen, an important source of protein,
and no fat).

Lunn says eggs are an excellent source of B vitamins, which are needed for vital
functions in the body, and also provide good quantities of vitamin A, essential for
normal growth and development.

An egg’s vitamin E content protects against heart disease and some cancers; there’s
also vitamin D, which promotes mineral absorption and good bone health.

Eggs are rich in iodine, for making thyroid hormones, and phosphorus, essential for
healthy bones and teeth.

Teenage girls who eat an egg a day may give themselves additional protection against
breast cancer in later life, according to a study in the journal Breast Cancer Research.

It is the essential nutrients in eggs, such as amino acids, vitamins and minerals, that
may be responsible for this protection.

Egg yolks contain the nutrients lutein and zeaxanthin, which could help to prevent or
even reverse the age-related eye problem macular degeneration (MD).

This is one of the leading causes of blindness and occurs as a consequence of getting
older — however, low lutein intake is implicated as a risk factor.

Eggs are also low in calories — a large egg contains only 75 calories and 5 grams of
fat — and other research suggests they can help you lose weight. A study published
last year in the Journal of the American College of Nutrition looked at the breakfast
habits of obese women.

Scientists from the Wayne State University in Detroit found that when the women were
given either an egg or bagel breakfast, each providing the same number of calories, the
women eating the eggs felt fuller and consumed fewer calories overall in the following
24 hours.

Health experts used to recommend a maximum egg consumption of three a week to avoid a
rise in blood cholesterol levels. But since evidence has shown that it is saturated fat
intake that affects cholesterol, advice has changed.

Now the Government’s Foods Standards Agency (FSA) says there is no limit as long as
they form part of a healthy, balanced diet.

According to the Food Standards Agency, ‘there’s nothing wrong with having them fried
occasionally’. If you do want a fried egg, use oil that is high in unsaturated fat,
such as sunflower oil. Drain off as much of the oil as you can, and it will also help
to pat the egg with some kitchen paper before eating.

And while eggs added as ingredients to foods such as cakes and pasta will provide the
same nutrients, you need to be careful the end product is not high in sugar and fat.

According to the British Egg Information Service, storing eggs correctly is vital to
aintaining their freshness and nutrient content.

They advise buying eggs only from a reputable retailer, keeping them in the fridge in
their box and eating by the use-by date.
