Trans fatty acid

In the spatial conformation of fatty acids, if hydrogen atoms are distributed on the same side of unsaturated bonds, they become cis-fatty acids. Conversely, hydrogen atoms on either side of unsaturated bonds are called trans fatty acids. Trans fatty acids are widely used in food processing to improve the taste and flavor of food. Today, we will introduce you to trans fatty acids. First, let’s discuss the health risks of trans fatty acids.

Lead to obesity

Trans fatty acids are not easily digested by the body and tend to accumulate in the abdomen, leading to obesity. People who like to eat snacks such as chips should be aware that trans fatty acids in fried foods can cause significant fat accumulation.

Increased risk of coronary heart disease

Excessive intake of trans fatty acids increases the risk of atherosclerosis and coronary heart disease. Studies have shown that trans fatty acids lower levels of good high density cholesterol (HDLC) and increase levels of bad low density cholesterol (LDLC).

Affect growth and development

High intake of trans fatty acids in pregnant or lactating women can affect the health of the fetus. Studies have found that the fetus or infant can passively absorb trans fatty acids through the placenta or milk, and they are more likely than adults to develop essential fatty acid deficiency, which affects the growth and development of the fetus and infant. In addition, it also affects the absorption of essential fatty acids in growing adolescents. Trans fatty acids can also adversely affect the growth and development of the central nervous system in adolescents.

Trans fatty acids have been linked to an increased risk of blood clots, memory loss, an increased burden on the kidneys and reproductive function. According to the Dietary Nutrient Reference Intake of Chinese Residents (2013) edition, “the maximum limit of trans fatty acids derived from food industrial processing in the diets of children over 2 years old and adults in China is 1% of the total dietary energy”, which is roughly equivalent to 2g.

Which foods contain trans fatty acids?

The vast majority of trans fatty acids consumed in daily life come from processed foods, such as pastries, biscuits, cocoa butter substitutes, fried foods, and puffed foods. However, trans fatty acids are not usually found on many packaged food ingredient lists. So none of these foods contain trans fats? That’s not the case! Trans fatty acids are just a “waistcoat” hidden in the ingredients list! The following ingredients are trans fatty acids oh, recommended collection!

Hydrogenated vegetable oil, partially hydrogenated vegetable oil, hydrogenated vegetable oil, hydrogenated rape oil, hydrogenated fat, hydrogenated shortening, hydrogenated palm oil;

Refining: refined vegetable oil, refined palm oil, refined vegetable oil, refined coconut oil;

Artificial category: ghee, margarine, margarine, margarine butter, artificial fat;

Planting fat: planting fat, planting fat cream, planting fat end, planting fat creamer;

Others: Cocoa butter, creamer, shortening, shortening, vegetable butter, vegetable butter, trans fat, compound lipid ingredients, margarine, white oil, Snow White butter, etc.

In summary, when you see ingredients on the list that contain the words “hydrogenated” “ghee” “vegetable fat” “artificial oil” “refined oil” “cocoa butter” and so on, you should pay attention to it. It is very likely to contain a certain amount of trans fatty acids.

After reading the above content, many people have a question, why some food ingredients clearly have trans fatty acids, but the nutrition list is “0”? According to national regulations, if the trans fatty acid content is less than or equal to 0.3 grams per 100 grams of product, it can be labeled as “0”, so,? The “0” on the food label probably means that the product contains less than 0.3 grams of trans fat per 100 grams, not that it doesn’t.

Trans fatty acids are harmful to our health, so you must read the food label carefully to know how to eat. Remember to eat no more than 2g of trans fat a day!
