Butter Worse For Arteries Than Olive Oil
Tuesday, April 1, 2014
Meals high in saturated fat (SAFA), as opposed to monounsaturated fat (MUFA), may impair artery function. That was the finding of a small study published in the December issue of Diabetes Care:Differential Effects Of Two Different Isoenergetic Meals One Rich In Saturated And One Rich In Monounsaturated Fat On Endothelial Function In Subjects With Type 2 Diabetes Mellitus, Diabetes Care, December 2008
After 33 participants with type 2 diabetes consumed either a meal high in saturated fat (butter), or high in monounsaturated fat (olive oil), (meals had the same number of calories) their artery function was assessed.
Flow-mediated dilation (FMD):
- Declined by 16.7% after the saturated-fat-rich meal
- Increased by 5.2% after the monounsaturated-fat-rich meal
The authors concluded:
"Consumption of an SAFA-rich meal is harmful for the endothelium, while a MUFA-rich meal does not impair endothelial function in subjects with type 2 diabetes."
DHA Omega 3 Fat Protects Arteries Heart and Can Prevent Blindness
Saturday, February 22, 2014
According to the result of a study published in the American Journal of Clinical Nutrition, a diet supplemented with the Omega-3 fatty acid DHA (Docosahexaenoic acid) can significantly lower the risk of sudden cardiac death, heart disease and visual degeneration leading to blindness.
Omega-3 Fats Provide Critical Protection Against Heart Attack
Another key component in the progression of cardiovascular disease is systemic inflammation that leads to unstable plaque known to rupture and cause a heart attack. Further evidence of the importance of DHA in lowering heart diseases risk is published in the journal Nature Chemical Biology. Researchers found that DHA influences the action of immune system macrophages. Working at the genetic level, DHA is shown to control the release of cellular antioxidants that inhibit the damage caused by excessive and chronic inflammation to the coronary arteries.
DHA Fat Dramatically Lowers Risk of a Fatal Stroke
The journal Science Translational Medicine reports the result of research that demonstrates how DHA regulated genes that can prevent blindness. DHA is highly concentrated in the retina and can control the abnormal growth of blood vessels in the eye that cause visual degradation. By halting unnecessary growth, DHA regulates vessel formation so that healthy blood vessels form and undesirable ones do not.
Fatty fish such as salmon, mackerel, herring and trout are ideal sources of Omega-3 fats including the DHA fraction. Due to the ever-increasing problem of mercury contamination in fish, supplementation is well advised. Nutrition experts recommend a molecularly distilled, dosage-controlled supplement that supplies 250 to 500 mg of DHA (not EPA and DHA combined, read labels caully) daily to dramatically lower the risks from heart disease, heart attack, stroke and blindness.
