If you’re yet to do your Christmas food shop, make sure you basket is full of greens.
A serving of green, leafy vegetables a day - such as spinach, kale or lettuce - has been linked to a younger brain, a new study has revealed.
People who ate at least one serving a day had a slower rate of decline on tests of memory and thinking skills than those who rarely ate the vegetables.
The difference between them was the equivalent of being 11 years younger in age, study author Martha Clare Morris, from Rush University Medical Centre in Chicago, said.
