What Are Trans Fatty Acids & What Foods Can I Find It In?
Trans fatty acids (TFAs) are unsaturated fatty acids.
Trans fatty acids occur naturally in animal fat, but are also produced industrially through the partial hydrogenation of vegetable oils.
There appears to be no benefit from consuming trans fat.
Instead, studies have consistently shown that artificial trans fatty acids can have serious side-effects.

Two Types Of Trans Fatty Acids
There are two types of trans fats found in foods: naturally occurring and artificial trans fats. source ◳
Naturally occurring trans fatty acids
Naturally occurring trans fatty acids are found in meat and dairy products as a result of anaerobic bacterial fermentation in ruminant animals. source ◳
Artificial trans fatty acids
Artificial trans fatty acids are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. source ◳
Industrially produced trans fats are much more common than natural trans fats.
How Do Trans Fats Get Into My Body?
When you eat a food or beverage with a high level of trans fats, they are almost immediately absorbed into your body and go directly into your bloodstream.
They are then carried to your organs, where they are stored.

Are All Trans Fatty Acids Bad?
There have not been sufficient studies to determine whether naturally occurring trans fats have the same bad effects as trans fats that have been industrially manufactured. source ◳
Studies have shown consistently that industrially manufactured TFAs increase cardiovascular risk and adversely affect blood lipids with a higher risk of developing type 2 diabetes. source ◳, source ◳
Trans Fatty Acids Through Hydrogenation Of Vegetable Oils
Trans fatty acids are the result of hydrogenation of vegetable oils, which is a process in which hydrogen is added to unsaturated fatty acids to change their structure and make them more solid.
Trans fatty acids are produced when hydrogen is added to unsaturated fats. These fats are a mixture of fatty acids, which can be saturated, monounsaturated or polyunsaturated.
According to the World Health Organization (WHO), TFAs are classified as carcinogenic.
But still, they are used in processed foods and most commercially available margarines and shortenings.
