Nutritional benefits have increased in past 30 years

If you enjoy telling younger members of your family that food just isn't as wholesome as it used to be, you might need to make an exception.
Eggs are far more nutritious and beneficial for our health than they were 30 years ago, scientists claim.
Not only have they found that eggs are lower in fat, cholesterol and calories, but they also contain more vitamin D than previously thought.
A major study, funded by the Department of Health, found that the average medium-sized egg now has nearly 25 per cent less saturated fat – which is linked to heart disease – than one sold in the 1980s. They contain 1.3 grams, rather than 1.7 grams. We are advised to eat no more than 20 grams of saturated fat a day.
The study also found they contain 177 micrograms of cholesterol, the substance which clogs arteries, just over 10 per cent less than the 202 micrograms previously recorded. They have fewer calories than experts originally thought, too – there are 66 in a medium egg, not 78.
