High dietary saturated fat intake is associated with higher blood concentrations of low-density lipoprotein cholesterol (LDL-C), an established risk factor for coronary heart disease. However, there increasing interest in whether various oils or fats different fatty acid profiles such as extra virgin coconut oil may have metabolic effects but trials reported inconsistent results. We aimed to compare changes lipid profile, weight, distribution and markers after four weeks consumption 50 g...

Abstract Background The identification of effective dementia prevention strategies is a major public health priority, due to the enormous and growing societal cost this condition. Consumption Mediterranean diet (MedDiet) has been proposed reduce risk. However, current evidence inconclusive typically derived from small cohorts with limited cases. Additionally, few studies have explored interaction between genetic risk dementia. Methods We used Cox proportional hazard regression models explore...
