The objective of the trial was to study the effects of a high carbohydrate intake and high fat diet on blood sugar, triglycerides and very low density lipoprotein (VLDL) cholesterol levels in patients with diabetes. the study included 10 men who were fed one of the diets for 28 days.
The diets were:
(i) 65% carbohydrate, 20% fat (high carbohydrate diet).
(ii) 38% carbohydrate, 45% fat (high fat diet).
The study found:
(a) The high carbohydrate diet caused significant rise in blood sugar levels, whereas no change was observed with the high fat diet.
(b) Compared with the high fat diet, the high carbohydrate diet also raised triglyceride and very low density lipoprotein (VLDL) cholesterol concentrations.
This study shows that high carbohydrate diets may cause rises in blood sugar, triglyceride and very low density lipoprotein (VLDL) cholesterol levels and therefore may not be desirable for diabetes patients.
