Animal source foods - wikipedia Animal source foods Jump to : navigation , search Various raw meats Animal source foods ( ASF ) include many food item that comes from an animal source such as meat , milk , eggs , cheese and yogurt . Many individuals do not consume ASF or consume little ASF by either personal choice or necessity as ASF may not be accessible or available to these people . Contents ( hide ) 1 Nutrition of animal source foods 2 Health impacts of micronutrient deficiency 3 Animal source food supplementation 4 Animal source food production 5 See also 6 References Nutrition of animal source foods ( edit ) Dunlop cheese from Ayrshire , Scotland . Aside from performed vitamin A , vitamin B and vitamin D , all vitamins found in animal source foods may also be found in plant - derived foods . Examples are tofu to replace meat ( both contain protein in sufficient amounts ) , and certain seaweeds and vegetables as respectively kombu and kale to replace dairy foods as milk ( both contain calcium in sufficient amounts ) . There are some nutrients which are rare to find in sufficient density in plant based foods . One example would be zinc , the exception would be pumpkin seeds that have been soaked for improved digestion . The increased fiber in these foods can also make absorption difficult . Deficiencies are very possible in these nutrients if vegetarians are not very careful and willing to eat sufficient quantities of these exceptional plant based foods . A good way to find these foods would be to search for them on one of the online , nutrient analyzing databases . An example would be nutritiondata.com . Most humans eat an omnivorous diet ( comprising animal source foods and plant source foods ) though some civilisations have eaten only animal foods . Although a healthy diet containing all essential macro and micronutrients may be possible by only consuming a plant based diet ( with vitamin B obtained from supplements if no animal sourced foods are consumed ) , some populations are unable to consume an adequate quantity or variety of these plant based items to obtain appropriate amounts of nutrients , particularly those that are found in high concentrations in ASF . Frequently , the most vulnerable populations to these micronutrient deficiencies are pregnant women , infants , and children in developing countries . In the 1980s the Nutrition Collaborative Research Support Program ( NCRSP ) found that six micronutrients were low in the mostly vegetarian diets of children in malnourished areas of Egypt , Mexico , and Kenya . These six micronutrients are vitamin A , vitamin B , riboflavin , calcium , iron and zinc . ASF are the only food source of Vitamin B. ASF also provide high biological value protein , energy , fat compared with plant food sources . Health impacts of micronutrient deficiency ( edit ) All six micronutrients richly found in ASF , vitamin A , vitamin B , riboflavin , calcium , iron and zinc play a critical role in the growth and development of children . Inadequate stores of these micronutrients , either resulting from inadequate intake or poor absorption , is associated with poor growth , anemias ( iron deficiency anemia and macrocytic anemia ) , rickets , night blindness , impaired cognitive functioning , neuromuscular deficits , diminished work capacity , psychiatric disorders and death . Some of these effects , such as impaired cognitive development from an iron deficiency , are irreversible . However , ASF foods have been shown to raise the risk of heart disease , diabetes , cancer , obesity and other preventable diseases due to the high levels of saturated fat and cholesterol . Animal source food supplementation ( edit ) Micronutrient deficiency is associated in poor early cognitive development . Programs designed to address these micronutrient deficiencies should be targeted to infants , children , and pregnant women . To address these significant mirconutrient deficiencies , some global health researchers and practitioners developed and piloted a snack program in Kenya school children . However , some communities are vegetarians for religious or cultural reasons . Efforts must be made to develop culturally appropriate interventions to address the micronutrient deficiencies in these populations , such as through food fortification .

( August 2009 ) ( Learn how and when to remove this template message ) Further information : Environmental effects of meat production According to a 2006 United Nations initiative , the livestock industry sector emerges as one of the top two or three most significant contributors to the most serious environmental problems , at every scale from local to global . '' As such , using plant - derived foods is typically considered better for the interests of the environment . Despite this , the raising of certain animals can be more environmentally sound than others . According to the Farralones Institute 's report from 1976 , raising rabbits , and chickens ( on a well - considered approach ) for food can still be quite sustainable . As such , the production of meat and other produce , such as eggs , may still be considered environmentally friendly ( if this is done in an industrial , high - efficiency manner ) . In addition , raising goats ( for goat milk and meat ) can also be environmentally quite friendly and has been favored by certain environmental activists , such as Mohandas Gandhi .
