My primary source of nutritional research (in one spot) is the research conducted by Dr. Walter Willett at Harvard Public Health. Their book 'Eat, Drink, and be Healthy' summarizes the findings of two very large studies--The Nurses' Health Study, and The Physicians' Health Study (also incorporates the Framingham Heart Study). I rely heavily on this research as it is the only body of information I've been able to find that includes enough subjects over a significant period of time to have meaningful findings--100,000+ subjects over 20+ years. (Results obtained from 50 subjects over 6 weeks don't mean much).
I'm afraid I can't give you the link. The book is the source. I try not to put too much stock in internet-based medical information unless I can track it to a reliable source.
The research analysis examines different aspects of diet and other habits and through elimination and cross-referencing (way over my head). Anyway, their trends showed a couple things relevant to this discussion:
1. Overall fat content in the diet is not a predictor of mortality.
2. Overall *saturated* fat content in the diet shows a direct relationship with incidence of heart disease, syndrome X, and certain cancers.
Other key findings of interest are that excess body weight is second only to cigarette smoking as a predictor of mortality, and overall glycemic load does, in fact, affect one's likelihood of developing diabetes. (Findings are reported in the context of extensive controls to limit the effects of other factors.)
My statement was derived from combining this body of research with the smaller studies of the past couple of years indicating that blood lipids improve when low-carb/high fat diets are used for weight loss. Pairing the overall effects reported by Willett's group with the findings of the other smaller studies, the result was my statement--that excess saturated fats in non-losing state can be detrimental. I very deliberately used 'can'. Until someone specifically researches the topic of high saturated fat consumption in a low-carb context when not losing weight, a definitive statement is impossible.
Now, I'm certainly not trying to get rid of all saturated fats. A little context--I work full-time, go to college part time, and freelance part-time. A large proportion of my diet lately has consisted of cheeseburgers, cheese, and restaurant dinners--often steak. An inordinately high level of saturated fats (not to mention the other gunk you get from such foods). I'm just trying to pull back a bit. Also, I am the cook in the house, and my non-low-carb fiancee has high cholesterol. Finally, due to my blood sugar instabilities, even a low-to-moderate carb meal can have a temporary effect similar to that of a high-carb meal in a 'normal' person (glucose elevated too high), which leads me to believe that the effects on my triglycerides are similar too.
Did I cover everything?
