There are many aspects of a Nordic lifestyle that elicit admiration: their design ethic, their chic clothing brands and, not least, their ability to weather harsh winters. But now, there is another element to covet and adopt. Scientists have found that eating a Nordic diet – rich in poulty, fish and particular fruits- can help stave off brain decline in old age. Root vegetables, apples, pears and refined grains among other foods, were shown to help eaters preserve their mental faculties, which can in turn help fight dementia.
