Fast food is my familys biggest source of transfat in our diet. We are not eating out as much, and if we do we go to quality restaurants. Also we eat pretty healthy at home.

Trans fats occur naturally in the milk and body fat of ruminants (such as cows and sheep) at a level of 2-5% of total fat.[4] Natural trans fats, which include conjugated linoleic acid and vaccenic acid, originate in the rumens of these animals.
Animal-based fats were once the only trans fats consumed, but by far the largest amount of trans fat consumed today is created by the processed food industry as a side-effect of partially hydrogenating unsaturated plant fats (generally vegetable oils). These hydrogenated fats have displaced natural solid fats and liquid oils in many areas, notably in the fast food, snack food, fried food and baked good industries.
Partially hydrogenated oils are attractive to food manufacturers for several reasons. Partial hydrogenation reduces rancidity and consequently increases product shelf life and decreases refrigeration requirements. Because baking requires semi-solid fats, partially hydrogenated oils can replace the animal fats traditionally used by bakers (such as butter and lard); they are also a readily available alternative to semi-solid tropical oils such as palm oil. Because partially hydrogenated plant oils can replace animal fats, the resulting products can be consumed (barring other ingredient and preparation violations) by adherents to Kashrut (kosher) and Halal, as well as by adherents to vegetarianism in Buddhism, ahimsa in Jainism and Hinduism, veganism, and other forms of vegetarianism.
Foods containing artificial trans fats formed by partially hydrogenating plant fats may contain up to 45% trans fat compared to their total fat.[4] Baking shortenings generally contain 30% trans fats compared to their total fats, while animal equivalents such as butter and lard contain 3%. Those margarines not reformulated to reduce trans fats may contain up to 15% trans fat by weight.[5]
It has been established that trans fats in human milk fluctuate with maternal consumption of trans fat, and that the amount of trans fats in the bloodstream of breastfed infants fluctuates with the amounts found in their milk. Reported percentages of trans (compared to total fats) in human milk range from 1% in Spain, 2% in France and 4% in Germany to 7% in Canada.[6]
Trans fats are also found in shortenings commonly used for deep frying in restaurants. In the past, the decreased rancidity of partially hydrogenated oils meant that they could be reused for a longer time than conventional oils. Recently, however, non-hydrogenated vegetable oils have become available that have lifespans exceeding that of the frying shortenings.[7] As fast food chains routinely use different fats in different locations, trans fat levels in products can have large variation. For example, an analysis of samples of McDonald's french fries collected in 2004 and 2005 found that fries served in New York City contained twice as much trans fat as in Hungary, and 28 times as much trans fat as in Denmark (where trans fats are restricted). At KFC, the pattern was reversed with Hungary's product containing twice the trans fat of the New York product. Even within the US there was variation, with fries in New York containing 30% more trans fat than those from Atlanta.[8]
