Eating one to two servings of salad with spinach, lettuce and kale daily may keep your brain 11 years younger as well as prevent dementia, according to a study.
The study found that people who ate at least one serving of green, leafy vegetables a day had a slower rate of decline on tests of memory and thinking skills than people who never or rarely ate these vegetables.
In people who ate the most of green, leafy vegetables brain ageing slowed by 11 years.
