Young people can age biologically on a poor diet

A poor diet makes us biologically older than our actual age.

Biologically ageing can start early in life and could begin when we are just 20 years old, say researchers from the University of Jyvaskyla in Finland.

They have carried out a unique study that has assessed the impact of a poor diet on sets of twins aged between 20 and 25: one twin ate a diet of vegetables and fruits, while the other consumed processed and fast food, sugary drinks and red and processed meats.

Although the twins had similar genetic backgrounds, only the one eating the bad diet started to age biologically, the researchers found.
