For example, an editorial In the New England Journal of Medicine In 2014 about trans fatty acids
stated, "In the early 1990s, studies began [Italics mine] revealing negative health effects of trans fats, and by the mid-20005, It was clear beyond doubt that trans fats Increase the risk of coronary heart disease.
New research suggests that low levels of trans fatty acids
(TFAs) may not be as harmful to human health as previously thought, even if industrially produced, and may even be beneficial if they occur naturally in foods such as dairy and meat products.
They said: "A total ban on trans fatty acids
in processed foods might prevent or postpone about 7,200 deaths from coronary heart disease from 2015-20 and reduce inequality in mortality from coronary heart disease by about 3,000 deaths.
Dietary trans fatty acids
are primarily products of hydrogenation, which makes unsaturated oils solid at room temperature.
6) In order for a food product to be labelled "low in saturated fats", it must contain 2 g or less of a combination of saturated and trans fatty acids
per serving (or per 100 g for pre-packaged meals) and it provides 15% or less energy from the sum of saturated and trans fatty acid
Removing industrial trans fatty acids
is one of the most straightforward public health strategies for rapid improvements in health," they said.
Concern about trans fatty acids
is causing food manufacturers to seek alternative frying oils that have a similar oxidative stability to hydrogenated fats.
Reports published in a recent issue of the Archives of Ophthalmology reveal a protective effect for omega-3 fatty acids, fish, nuts, and olive oil, and an adverse effect for trans fatty acids
, on the risk of developing age-related macular degeneration.
And both trans fatty acids
and saturated fatty acids are associated with elevated risk, according to authors of an ARS-supported study.
The ratio of trans fatty acids
(TFAs) to omega-3 fatty acids has been shown in several studies to have altered to favour TFAs, specifically trans-9 18:1 and trans-10 18:1 fatty acids.
Although we did not find a significant association between the class of total trans fatty acids
and the MetS, we did find a significant inverse association (P <0.
