Corn Oil

I watched a video recently on YouTube with Dr. David Servan Schreiber, a french physician,  neuroscientist and author who battled malignant brain tumor.  In his video he advocates against the use of corn oil. He explained the correlation between the production of corn oil and incidences of cancer in the US.

This got me thinking. I have been using corn oil or sunflower oil all my life. Its the cheapest oil and most widely available. However after watching this video I started googling for health benefits on corn oil and i could not find much material. Finally resorting to wikipedia the following was stated under negative health effects:

Some medical research suggests that excessive levels of omega-6 fatty acids, relative to omega-3 fatty acids, may increase the probability of a number of diseases and depression.^[3][4][5] Modern Western diets typically have ratios of omega-6 to omega-3 in excess of 10 to 1, some as high as 30 to 1, partly due to corn oil which has an omega-6 to omega-3 ratio of 49:1. The optimal ratio is thought to be 4 to 1 or lower.^[6][7]
A high intake of omega-6 fatty acids may increase the likelihood that postmenopausal women will develop breast cancer.^[8] Similar effects were observed on prostate cancer.^[9] Other analysis suggested an inverse association between total polyunsaturated fatty acids and breast cancer risk.^[10]

Most of us buy products without putting much thought. We see a cooking oil that says enriched with Omega 3 and we think its good. Then we see another one that says Omega 3 and Omega 6 and we think this must be better. Not knowing if we need it or what it does in the body.

In summary Corn oil is not good for you as it contains a high omega 6 to omega 3 ratio which can lead to diseases. Try to switch to alternatives like coconut and olive oil where possible limit corn oil to frying if necessary.
