Products bearing the USDA certified organic seal must contain at least 95 percent organic ingredient, and must be produced without the use of synthetic pesticides and fertilizers and free of genetically engineered ingredients.

Dairy cows were not treated with synthetic bovine growth hormone (rBGH).

High fat dairy products, beef, and seafood are key sources of dioxin and other persistent pollutants in the diet. Eat less fatty meats and dairy to reduce your intake of these pollutants.

Both refined oils and fully hydrogenated oils contain small amounts of unhealthy artificial trans fats and contribute to the total intake of trans fat in the diet (Biofortis 2014). Artificial trans fats are generated in refined oils when they are processed at high temperatures from the crude oil into a bland, odorless, colorless oil (Greyt 1999). A 2012 study conducted by FDA scientists estimated that refined oil contributes an average 0.6 grams of trans fat a day (Doell 2012). The World Health Organization recommends limits on trans fat of less than 1 to 2 grams a day—in this context, it’s easy to see that 0.6 grams is not an insignificant contribution. In the case of fully hydrogenated oils, they should theoretically be free of trans fat, but since no hydrogenation process is 100 percent efficient, trans fats are often found in fully hydrogenated oils at low levels (FDA 2013). The United States Department of Agriculture National Nutrition Database has tested refined, partially hydrogenated and fully hydrogenated oils and found trans fats in all of them (USDA 2013). Textbooks for food scientists reveal that the mono and di-glycerides and other emulsifiers are often made from hydrogenated fats (Hasenhuettl and Hartel 2008) and at temperatures above 220°C (Sikorski and Kolakowka 2011). Emulsifiers produced from hydrogenated fats “contain measurable concentrations" of trans fats (Hasenhuettl and Hartel 2008). Unfortunately, due to lack of label disclosure and the trans fat labeling loophole, only the food scientists will ever know just how much trans fat these refined oils and emulsifiers are contributing to foods and the American diet.

Saturated fat is not an essential nutrient and with increasing intakes there is a increased risk of coronary heart disease (IOM 2005a; USDA and DHHS 2010). For this reason it has long been known as a "bad" fat that raises the "bad" cholesterol, LDL. Numerous authoritative bodies support the recommendation to limit saturated fat to 10 percent of calories -- equivalent to a reasonable limit of 14 slices of bacon's worth of saturated fat a day (WHO 2002; USDA and DHHS 2010). A 2012 review by the Cochrane Collaboration, an independent non-profit organization, found that reducing or replacing saturated fat with other healthy fats reduced the risk of cardiovascular events by 14 percent (Hooper 2012). Other recent reviews have found that there in no evidence of a benefit from reducing saturated fat (Chowdhury 2014; Schwingshackl & Hoffmann 2014). While it's clear that we still have a lot to learn about how fats behave and contribute to disease, the evidence supporting a moderate level of saturated fat consumption remains strong and consistent.
