Q) Does eating cholesterol really impact cholesterol level?
We have know for years that saturated fat is the true culprit to raising LDL production by our body. One should decrease their saturated fat intake to decrease their LDL (Low Density Lipoprotein- aka bad cholesterol). Many people have misunderstood this for years. The focus should not be on a cholesterol free product such as palm oil but rather a lower saturated fat and higher monounsaturated fat like almonds. Decreasing dietary cholesterol intake lowers your LDL about 3-5% where as decreasing your saturated fat intake decreases your LDL by 8-10% as reported by the National Cholesterol Education Program.
Q) Will this depend on other nutrients that the food contains? If it’s not, what does impact cholesterol levels then?
Yes, levels of saturated fat, monounsaturated fats, polyunsaturated fats, exercise, stress and genetics all effect our cholesterol levels. A favorable fat profile of a food should look like this >Monounsaturated fats> Polyunsaturated Fats> Saturated Fats (need more research as to which saturated fats may be more beneficial).
Q) What about coconut oil and is it true it may help you to lose weight?
The American Dietetic Association does not recommend consuming tropical oils such as Coconut oil. According to the Natural Medicines Database, ”there is insufficient evidence to rate the effectiveness of coconut oil for weight loss, hypercholesterolemia, diabetes, chronic fatigue, Crohn’s disease, irritable bowel syndrome and thyroid conditions.”
Q) From the types of saturated fats such as stearic acid, lauric acid, etc, are there any with health benefits?
Per the research I have found, there are not saturated fats with absolute health benefits. To be prudent, one should continue to limit their saturated fat intake at this time and replace them with unsaturated fats, fruits, vegetables and whole grains. For additional reference there is a chart that clearly identify the roles of saturated fat on medscape: Role of Different Dietary Saturated Fatty Acids for Cardiometabolic Risk, By David Iggman; Ulf Risérus Posted: 04/28/2011; Clin Lipidology. 2011;6(2):209-223. © 2011 Future Medicine Ltd.
