But they also make the food last longer on shelves; unlike liquid fats, trans fats take a long time to break down. Many processed foods use trans fat-containing oil in some capacity—cookies and cakes are baked with it, potato chips or microwave popcorn are fried in it. Some types of margarine are just a solid version of these oils. For a long time there was no scientific consensus on whether or not trans fats were really as bad as they seemed.
Studies intended to determine the long-term effects of these fats on the human body found that they caused significant damage to the heart and arteries. The FDA kept asking for more research, more information, before taking a strong stance, likely because of pressure from the food industry.
But in the FDA was forced to act when a university professor sued the organization for not banning trans fats sooner. Although intake has declined in recent years as awareness has increased and regulators have restricted their use, trans fats still pose a public health problem. Natural, or ruminant, trans fats occur in the meat and dairy from ruminant animals, such as cattle, sheep, and goats. Several reviews have concluded that a moderate intake of these fats does not appear harmful 3 , 4 , 5.
The best-known ruminant trans fat is conjugated linoleic acid CLA , which is found in dairy fat. It is believed to be beneficial and is marketed as a dietary supplement 6 , 7 , 8 , 9.
However, artificial trans fats — otherwise known as industrial trans fats or partially hydrogenated fats — are hazardous to your health. These fats occur when vegetable oils are chemically altered to stay solid at room temperature, which gives them a much longer shelf life In a series of clinical studies, people consuming trans fats instead of other fats or carbs experienced a significant increase in LDL bad cholesterol without a corresponding rise in HDL good cholesterol.
Similarly, replacing other dietary fats with trans fats significantly increases your ratio of total to HDL good cholesterol and negatively affects lipoproteins, both of which are important risk factors for heart disease Indeed, many observational studies link trans fats to an increased risk of heart disease 14 , 15 , 16 , Both observational studies and clinical trials suggest that trans fats significantly increase your risk of heart disease.
The relationship between trans fats and diabetes risk is not completely clear. However, two similar studies found no relationship between trans fat intake and diabetes 19 , Several controlled studies examining trans fats and diabetes risk factors, such as insulin resistance and blood sugar levels, show inconsistent results 21 , 22 , 23 , 24 , That said, animal research reveals that large amounts of trans fats harm insulin and glucose function 26 , 27 , 28 , Trans fats may drive insulin resistance and type 2 diabetes, but the results from human studies are mixed.
Excess inflammation is thought to be a primary cause of many chronic illnesses, such as heart disease, metabolic syndrome, diabetes, and arthritis. Two studies indicate that trans fats increase inflammatory markers when replacing other nutrients in the diet — but another study switched butter for margarine and found no difference 31 , 32 ,
