The key to a longer life is eating a healthy and balanced diet, but experts are now recommending eating a certain food which isn’t usually associated with this.
Eating chocolate, as well as drinking coffee and tea, can help you live longer, according to a new study.
But, in order to gain the benefits, these must be consumed with a zinc supplement.
The study was carried out by the University of Erlangen in Nuremberg and Auburn University in Alabama.
Researchers found the combination of the supplement with chocolate, tea and coffee can add years on to a person’s life by protecting against “oxidative stress”.
They described this as the gas that leads to ageing and illnesses such as cancer and degenerative diseases.
Zinc is known for helping the body fight bacteria and viruses and chocolate, tea and coffee contain antioxidant polyphenols.
On their own, the polyphenols in theses foods can’t break down oxidative stress, but with the help of zinc, they create a “mega complex” enzyme, which can help protect the body from the damaging waste gas created by the body’s cells.
Lead author of the study, Dr Ivana Ivanovic-Burmazovic, concluded: “It is certainly possible that wine, coffee tea or chocolate may well be available in future with added zinc.”
But the wine would have to be non-alcoholic, as “any alcohol content whatsoever would destroy the positive effects of this combination”.
Zinc supplements are available on the high street – 100 tablets are around £6.
But whether they’re fried, scrambled, poached or whisked into omelette, how many eggs should you be eating a week?
Around six eggs a week is the recommendation by dietician Juliette Kellow and medical consultant Dr Sarah Brewer.
In their book titled ‘Eat Better Live Longer’, the pair say among eggs’ benefits are improved heart health.
They write: “Eggs may have a high cholesterol content, but current research shows that cholesterol in food generally has little impact on blood cholesterol levels or heart disease risk (except for people with a genetic condition called familial hypercholesterolaemia).”
There are some nutritional differences between different eggs.
The duo say hen eggs provide good-quality protein, which is important for healthy muscles.
They add that they “contain a range of B vitamins and choline, essential for brain function” and “vary depending on the type, for example there are omega-3-enrinched and organic eggs.
“An organic egg yolk may contain more protein and potassium than a regular egg yolk.
Quail eggs are rich in iron, but you need to eat three quail’s eggs to get the same amount of iron as from one hen’s eggs.
Duck eggs contain five times more vitamin A then regular hen’s eggs, but do contain more fat.
