Trans Fat Cover-Up [1]

Trans Fat Cover-Up [1]
After more than three decades of intense scrutiny by researchers attempting to prove that tropical oils are harmful, the oils have come out squeaky clean. Not only have they been proven not to promote heart disease, but evidence shows that they can protect against it.

Many of the studies done in the 1960s and 1970s which implicated saturated fat as a possible contributor to heart disease were actually done using hydrogenated vegetable oils, not saturated fats. Complete hydrogenation turns unsaturated fats into saturated fats. Most researchers thought that it didn't matter where the saturated fats came from so long as they were saturated. At the time they didn't know there was a difference between natural saturated fats and hydrogenated fats.

Hydrogenated palm and coconut oils were often used. People reading the studies ignored the term "hydrogenated" and simply associated palm and coconut oil with the negative results they were finding. It didn't matter if they used hydrogenated palm, coconut, or soybean oil, hydrogenated oil from any source raised blood cholesterol.

The detrimental effects of trans fatty acids were suspected as far back as the 1950s. Some researchers at the time even suggested that they may cause or contribute to heart disease. Research throughout the 1960s and 1970s also showed that hydrogenated fats produced a number of adverse health effects in lab animals. One of the primary concerns was the effect of trans fatty acids on essential fatty acid (EFA) utilization. Eating hydrogenated oils could cause EFA deficiency.

One of the symptoms of EFA deficiency is elevated cholesterol - a risk factor for heart disease. Hydrogenated fats not only raise total cholesterol but also LDL, the so-called "bad" cholesterol, and lowers HDL, the "good" cholesterol. Trans fatty acids block prostaglandin synthesis which leads to hormonal imbalance, stunts testicular development in the young, and causes testicular generation in mature animals. Trans fats in the diet are incorporated into cells and alter composition of tissues throughout the body. Higher levels of fat accumulate in the heart, liver and other organs. Tran fats retard kidney development, stunt growth and interfere with blood sugar metabolism. Nursing mothers who eat hydrogenated oils pass trans fatty acids to their children through their breast milk.

Much of this was known and available in published studies by the mid 1980s, even before the vegetable oil industry started their anti saturated fat campaign and their push to replace tropical oils with hydrogenated oil, explaining why industry representatives always alluded to replacing saturated fats with "vegetable" oil rather that "hydrogenated vegetable" oil. If the public knew that the vegetable oil industry was planning on using hydrogenated oils, they would have had a bigger fight on their hands.
