Butter versus Margarine and other confusing "medical" data

It seems that the debate of the benefits of butter over margarine, or visa versa, is still raging.  For the last 60 years I have heard arguments from both sides as saturated competes with unsaturated fats.   Of course, the latest study is rarely the final answer.  So I take the latest information with a good pinch of (non-sodium, of course) salt.

In a recent newsletter from Dr. Mercola he says: “A review from Cambridge University, just published in the journal Annals of Internal Medicine, is the latest analysis to confirm the absolute lack of evidence that consuming saturated fat leads to heart disease. They also found no basis for guidelines that advise increased consumption of polyunsaturated fats to lower your cardiac risk, calling into question all the standard nutritional guidelines related to heart health.” http://articles.mercola.com/sites/articles/archive/2014/03/24/butter-con... So, what is one to believe?

The latest edition of Nutrition Action also does little to either clarify or correct preconceived thinking on the benefits of specific nutritional supplements.  There is so much apparently conflicting information.  Our daily newspapers may report a synopsis of findings that is misleading because it is only an extract from the complete study.  Yet reading the entire report sometimes needs a much more scientific knowledge to really understand and interpret correctly.  

Often one hears from one’s doctor that it is unnecessary to take supplements because really all one needs to do is eat “correctly.”  Really what does that mean?  Food today is far different to food even 50 years ago.  One wonders whether this is taking into account the poor quality of soil due to overproduction, increasing use of pesticides or genetically modified products.  How does one read between the lines and establish a true picture?

To add to the problem, there is a plethora of books touting the latest fad diets, how to effectively lose weight and how to live well into old age.  One may examine these and the argument seems so reasonably plausible. Is this the truth or is this someone's ticket to the New York Times Best Seller’s List?

Perhaps our motto and guiding principle should be “moderation in all things.”

Meanwhile, I was down in Mexico and in the two weeks of my visit lost 5 lbs in weight. Admittedly I was visiting the gym regularly.  However, the only other variable was that I was consuming tortilla corn chips and drinking certainly my fair share of Margaritas.  I contemplate using my findings and writing the next Best Seller of something that the masses would willingly embrace.
