Re: Re-evaluation of the traditional diet-heart hypothesis: analysis of recovered data from Minnesota Coronary Experiment (1968-73)

This review on 'LA' rich foods was a little disappointing. Corn and corn oil have been shown to contribute to heart disease, especially when fed to cows that are raised for human consumption. The research paper is using a blanket statement of all LA rich foods, not specifically corn or fried foods. I believe labeling and categorizing corn oil in the same group as flax is incorrect and it is also incorrect to imply that fried and fresh is the same. While my nutrition background tells me that many other LA rich foods are high in antoxidants and that corn is not, which might have something to do with it, blanketing corn oil as a representative of all other LA foods, especially when used for frying is bad science. Research studies will show a higher correlation of heart disease when comparing 'LA' rich corn oil to flax oil among others. I am not sure if that makes a difference in your position, but I thought it might help to shed light on the problems/issues instead of spreading misinformation (I had to dig to find the details).
