The Age Code Argues Food May Shape How We Age

David Cox’s book asks whether the food we eat affects how our bodies age.

Your calendar age counts the years since you were born.

Biological age describes how old your body seems to be based on damage and repair inside it.

People can have different biological ages even when they are the same calendar age.

Cox changed his diet and found that some health measurements improved.

He also found signs that his body may have been ageing more slowly after eating more fibre.

The book says food is important, but exercise, sleep, stress, genes and living conditions matter too.

It does not offer one perfect diet for everyone.

Its main message is that living longer should also mean staying healthy for more of those years.
