The four groups were renamed: Meat and Alternatives, Grain Products, Vegetables and Fruit, and Milk Products. A fifth group of "Other Foods" made its appearance overleaf. A change in philosophy was noted too: whereas previous food guides had been based on a "foundation diet", whereby diet was identified with "minimum requirements" and those persons with "higher needs" were instructed to consume more food, the 1992 guide identified a "total diet" approach, under which the range of "different ages, body sizes, activity levels, genders and conditions such as pregnancy and nursing" theoretically were accommodated, and with the caveat "that energy needs vary". The consumer was subtly prodded to increase their consumption of grain products while they minimised their consumption of meat products, through the suggestive "rainbow" that was in reality an areal subterfuge. The consultative process to develop the 1992 guide was novel to bureaucrats who formerly had used a hierarchical approach: "information was assembled from experts, consumers, literature reviews, food consumption surveys, consumer research, and commissioned scientific reviews". A 16-page booklet was developed in addition to the recto-verso poster that had been issued in former years. A food guide in both official languages was produced and for the first time made available via the internet. A "Food Guide Facts - Background for Educators and Communicators" booklet was intended to help teachers plan their classes. 2007 The year 2007 saw for the first time an ethnoculturally specific Guide: the Food Guide for First Nations, Inuit and Métis people was introduced. The name of the main guide evolved to Eating Well with Canada's Food Guide. The guide expanded to six pages in a fold-out pamphlet, with new content addressing the multicultural population of Canada. Obesity was recognized as a dietary problem. The Milk Products group became known as the Milk and Alternatives group, as "fortified soy beverage" was officially introduced to accommodate "non-milk drinkers". A guidance to reduce consumption of trans fats and replace saturated fats with unsaturated fats was identified. Instead of the cod-liver oil of days gone by, Canadians over 50 years of age were now invited to consume vitamin D dietary supplements. The choice of healthy foods was linked to the food label. Nine age and sex groups were identified for specific recommendations. "Three Advisory Groups provided guidance and advice throughout the revision process – the DRI Expert Advisory Committee, an Interdepartmental Working Group and the Food Guide Advisory
