Avocado

This is the only fruit that provides decent amounts of monounsaturated fatty acids, which have been shown to reduce heart attack risk and inflammation. As we age, the body is almost permanently in a threat state, dealing with ageing cells and broken DNA.

This chronic, low-grade inflammation alters communication within each cell and is a hallmark of ageing – so much so that doctors have coined the term “inflammageing”.

It’s linked to type 2 diabetes, cognitive decline, reduced immunity, cancer and cardiovascular disease.

High levels of inflammation are found in people who become frail as they age.
