Today, most of the people believe that vegetable oils like soy oil, corn oil, safflower oil and canola oil are fats better than animal fats. But this is NOT true. These polyunsaturated fats are connected to cancer, heart disease, immune system dysfunction, damage to the liver, reproductive organs and lungs, digestive disorders, depressed learning ability, impaired growth, and weight gain.
The reason behind is they can easily become oxidized or rancid, resulting in a lot of free radicals, which can attack cell membranes and red blood cells, causing damage in DNA/RNA strands. Therefore, tissues, organs and blood vessels are damaged, leads to premature aging, development of tumors, etc.
In these commercial vegetable oils, the ratio of omega-6 linoleic acid is too high when compared to omega-3 linoleic acid, which links to blood clots, high blood pressure, irritation of the digestive tract, and much more.
In short, AVOID these commercial vegetable oils. Not just avoid using them in cooking, but also avoid store bought processed food as many as you can, as you can always read “Vegetable Oil” on their labels!
