What is the Nordic diet — and why do doctors, dietitians and even psychiatrists like it so much?

It’s difficult if not impossible to define an “American” diet. The U.S is so diverse, so multicultural and so successful at importing foods from elsewhere; and yet one thing remains sadly true on a general level: we’re not terribly healthy. As a nation we consume too much of the bad stuff (added sugars, saturated fats and sodium) and not enough of the good stuff (vegetables, fruits, dairy and healthy oils). Obesity rates continue to rise, not only among adults, but also among our children.
