 While a GDA for calorific intake might represent a broad target in so far as people need to take in a minimum of calories to survive, the GDA for saturated fat is not a target, as ingesting no saturated fats at all would not be harmful to health, so long as there were fats of a non-saturated variety in the diet.GDAs are now in widespread use across the food industry and appear both on the front and back of food packaging.In 2014, GDAs were beginning to be replaced by reference intakes.
