Vegetable Oil Lower Cholesterol, but Trigger Heart Disease

Polyunsaturated fats known as omega - 3 and omega - 6 are known to have important benefits for health . However, a recent review of several studies suggest , polyunsaturated fats are not necessarily have such benefits that have been claimed many food labels .

According to a review published Canadian Medical Association Journal , especially in vegetable oils that claim to contain omega - 6 , but lack of omega - 3 actually has a negative effect on health . This is due to an imbalance of polyunsaturated fats in it .

The researchers assert , certain vegetable oils should not be categorized as a healthy food . Because , these products only contain omega - 6 fatty acids are high and low in omega - 3 , so it is not balanced .

In general , replacing saturated fats with polyunsaturated fats may reduce the risk of death from coronary heart disease ( CHD ) . But according to the researchers , if not balanced , polyunsaturated fatty acids may not be able to mitigate those risks.

Know the unsaturated fatty acids

Components in foods can be broken down into several chemical elements . Fat is a component found in many types of food , especially meat and beans . Type of fat that can be found within each different type of food , such as saturated fat , monounsaturated , and polyunsaturated . Such as the types of fat that has a different chemical structure .

In fact , without a polyunsaturated fat , the brain can not function properly . However, because the body can not produce itself , then we need to eat certain foods that contain these nutrients .

Especially omega - 3 fatty acids are found in fatty fish such as salmon , mackerel , and tuna . These nutrients can also be found in walnuts . Meanwhile , omega - 6 fatty acids are found in nuts and seeds , such as vegetable oils such as corn oil , soybean oil , and sunflower oil .

Omega - 3 fatty acids may reduce the risk of heart disease and stroke . While omega - 6 is known to reduce "bad" cholesterol or low density lipoprotein ( LDL ) .

Well , because the two types of polyunsaturated fatty acids have long been well known for health , then a new analysis from the University of Toronto is pretty much a surprise . They even found that vegetable oils rich in omega - 6 fatty acids but no omega - 3  by itself increase the risk of heart disease .

Analysis of " imbalance " is based on a study published last February . The study involved a group of participants who changed their fat consumption to vegetable oil . rich in omega - 6 fatty acids but low in omega - 3 .

As a result, levels of "bad" cholesterol in their body is reduced , but there is an increase in the rate of death from cardiovascular disease and CHD . Therefore, they conclude , the consumption of vegetable oils rich in omega - 6 alone is not enough to reduce the risk of death associated with cardiovascular disease , but also must be balanced with the consumption of omega - 3 fatty acids .
