Despite limitations in these data , our NMA findings are in line with existing evidence on the metabolic effects of fat and support current recommendations to replace high saturated-fat food with unsaturated oils
The aim of this network meta- analysis ( NMA ) is to compare the effects of different oils/solid fats on blood lipids .
Mediterranean alpha-linolenic acid-rich diet in secondary prevention of coronary heart disease
In a prospect i ve , r and omised single-blinded secondary prevention trial we compared the effect of a Mediterranean alpha-linolenic acid-rich diet to the usual post-infa rct prudent diet .  After a first myocardial infa rct ion , patients were r and omly assigned to the experimental ( n = 302 ) or control group ( n = 303 ) . Patients were seen again 8 weeks after r and omisation , and each year for 5 years . The experimental group consumed significantly less lipids , saturated fat , cholesterol  , and  linoleic acid  but more  oleic  and  alpha-linolenic acids  confirmed by measurements in plasma . Serum lipids , blood pressure , and body mass index remained similar in the 2 groups . In the experimental group , plasma levels of albumin , vitamin E , and vitamin C were increased , and granulocyte count decreased . After a mean follow up of 27 months , there were 16 cardiac deaths in the control and 3 in the experimental group ; 17 non-fatal myocardial infa rct ion in the control and 5 in the experimental groups : a risk ratio for these two main endpoints combined of 0.27 ( 95 % CI 0.12 - 0.59 , p = 0.001 ) after adjustment for prognostic variables . Overall mortality was 20 in the control , 8 in the experimental group , an adjusted risk ratio of 0.30 ( 95 % CI 0.11 - 0.82 , p = 0.02 ) . An alpha-linolenic acid-rich Mediterranean diet seems to be more efficient than presently used diets in the secondary prevention of coronary events and death
