High levels of C-reactive protein and triglycerides are associated with an increased risk of heart disease. See here and here.
This study investigated the effects of 3 diets on diabetes and heart disease risk factors, such as weight, triglyceride levels and C-reactive protein levels in 96 overweight insulin-resistant women.
The diets were either:
(i) High-carbohydrate, high-fibre diet
(ii) High-protein diet
(iii) High-fat diet
The study found:
(a) When compared with the high carbohydrate diet, the high fat and high protein diets were shown to produce significantly greater reductions in weight loss.
(b) When compared with the high carbohydrate diet, the high fat and high protein diets were shown to produce significantly greater reductions in triglyceride levels.
(c) All diets reduced C-reactive protein levels. The high carbohydrate diet reduced them by 14.8% and the high protein diet by 17.3%. However by far the largest decrease in the dangerous C-reactive protein levels was on the high fat diet, with a 52.6% reduction.
This study reveals how a high fat diet is effective in reducing the risk of heart disease, with weight loss and the reduction of heart disease risk factors such as triglyceride and C-reactive protein levels.
