Navigating Oleic Acid: Its Uses, Sources, And Side Effects

Did you know what makes olive oil different from other edible oils? Yes, it is the healthier choice and good for your cholesterol, but what makes it different? The answer is Oleic acid. It is a monounsaturated omega fatty acid. This compound has 18 hydrogen chains with a single double bond of omega-9. 

Edible oils these days are claiming to have monounsaturated fatty acids in them to increase their health quotient. Apart from olive oil, you can find oleic acid in almond oil, sunflower oil, sesame oil, peanut oil, and rapeseed oil. So how does oleic acid work? In this blog, we are going to unravel the mystery that is oleic acid, its uses, sources, and side effects.

What Makes Oleic Acid Important?

Oleic Acid is one double bond in its carbon chain which helps it to be a healthier choice than others. This bend in the chain makes the oil remain liquid even at a cold temperature. This helps with your heart health and reduces inflammation in your body. You can now enjoy fried meals with the help of oleic acid. 

The more unsaturated fat is stored in the oil, the more likely it is to keep your health in check. As opposed to saturated fat, which increases your low-density lipoprotein (LDL) a.k.a bad protein. These LDLs can cause your artery walls to build up and cause blood clotting, stroke, or heart failure.

➡️Weight Management

How can we forget the body mass weight when we are talking about the health benefits? The reason why oleic acid is popular in demand is because it is a healthier choice and regulates LDLs. These LDLs are not only worse for your heart, but also your body weight. Using olive oil or any oil with oleic acid as a major component helps you curb the feelings of hunger. The meals prepared in these oils give you the feeling of fullness. 

➡️Skin And Health

Oleic acid does not only work internally but also is beneficial for your skin. Beauty products with oleic acid can slow the aging process and work as a great moisturizer.
