Passage 2:Habesha peoples: /Habesha/ or /Abesha/ ((rarely Habeshat: ), or rarely used exonyms like "Abyssinian people," "Aithiops: ," "Athtiu-abu: Ancient Egyptian: Athtiu-abu ~ 'robbers of hearts' ~," or "al-Habas/al-Habasi (al-Habash/al-Habashi): Mehri in Arabic script: / ~ 'incense gatherers' ~". Habesha () ) is a common pan-ethnic and meta-ethnic term used to refer to both Ethiopians and Eritreans as a whole. Certain definitions considered the Ethiosemitic-speaking and Agwa-speaking Cushitic peoples inhabiting the highlands of Ethiopia and Eritrea as the core ethnic groups that historically constituted the pan-ethnic group Habesha peoples, while this notion is only partially accepted. They historically include a linguistically, culturally and ancestrally related ethnic groups, conservatively-speaking mostly from the Ethiopian Highlands, but in a broader sense included other Ethiopian-Eritrean ethnic groups as well. Members' cultural, linguistic, and in certain cases, ancestral origins trace back to the Kingdom of Dmt, the Kingdom of Aksum, among other kingdoms that either preceded or constituted the Ethiopian Empire in the Horn of Africa. Some Scholars have classified the Tigrayans and the Amhara as Abyssinians proper under an ultra-neo-conservative theory postulated by a few scholars and political parties but not widely accepted by the general public or by most indigenous scholars of the region.
Passage 3:The year 2007 saw for the first time a racially-tailored Guide: the Food Guide for First Nations, Inuit and Metis people was born. For all other Canadians, the name evolved to Eating Well with Canada's Food Guide. The recognition of the multi-cultural nature of Canada meant that the food guide needed to balloon, to six pages in a fold-out pamphlet as opposed to the recto-verso poster format that had been used in days of yore. Obesity was recognised 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 invited to consume vitamin D dietary supplements in order to normalise the method of ingestion by pharmaceutical pill. The choice of healthy foods was linked to the food label. A more "ethnically diverse" range of foods was depicted in order to reflect the European detonation of Canada. Nine age and sex groups were identified for specific recommendations but the LGBTQ lobby was still in its infancy and so no mention of them was made. "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 Committee". An "extensive consultation with a range of stakeholders regarding the 1992 Food Guide" was duly noted. The Dietary Reference Intake (DRI) tool from the American Institute of Medicine was introduced to the Canadian taxpayer, as the NAFTA made its presence felt on the dinner table.
