According to the network meta- analysis the Mediterranean diet is the most effective and efficacious dietary approach to improve glycaemic control in type 2 diabetes patients
The aim of the present study is to assess the comparative efficacy of different dietary approaches on glycaemic control in patients with type 2 diabetes mellitus using a systematic review of the literature .
Egg consumption as part of an energy-restricted high-protein diet improves blood lipid and blood glucose profiles in individuals with type 2 diabetes.
The role of dietary cholesterol in people with diabetes has been little studied . We investigated the effect of a hypoenergetic high-protein high-cholesterol ( HPHchol ) diet compared to a similar amount of animal protein ( high-protein low-cholesterol , HPLchol ) on  plasma lipids , glycaemic control and cardiovascular risk markers in individuals with type 2 diabetes . A total of sixty-five participants with type 2 diabetes or impaired glucose tolerance ( age 54·4 ( sd 8·2 ) years ; BMI 34·1 ( sd 4·8 ) kg/m2 ; LDL-cholesterol ( LDL-C ) 2·67 ( sd 0·10 ) mmol/l ) were r and omised  to either HPHchol or HPLchol . Both hypoenergetic dietary interventions ( 6 - 7 MJ ; 1·4 - 1·7 Mcal ) and total carbohydrate : protein : fat ratio of 40:30:30 % were similar but differed in cholesterol content ( HPHchol , 590 mg cholesterol ; HPLchol , 213 mg cholesterol ) . HPHchol participants consumed two eggs per d , whereas HPHchol participants replaced the eggs with 100 g of lean animal protein . After 12 weeks , weight loss was 6·0 ( sd 0·4 ) kg ( P < 0·001 ) . LDL-C and homocysteine remained unchanged . All the subjects reduced total cholesterol ( - 0·3 ( sd 0·1 ) mmol/l , P < 0·001 ) , TAG ( - 0·4 ( sd 0·1 ) mmol/l , P < 0·001 ) , non-HDL-cholesterol ( HDL-C , - 0·4 ( sd 0·1 ) mmol/l , P < 0·001 ) , apo-B ( - 0·04 ( sd 0·02 ) mmol/l , P < 0·01 ) , HbA1c ( - 0·6 ( sd 0·1 ) % , P < 0·001 ) , fasting blood glucose ( - 0·5 ( sd 0·2 ) mmol/l , P < 0·01 ) , fasting insulin ( - 1·7 ( sd 0·7 ) mIU/l , P < 0·01 ) , systolic blood pressure ( - 7·6 ( sd 1·7 ) mmHg , P < 0·001 ) and diastolic blood pressure ( - 4·6 ( sd 1·0 ) mmHg ; P < 0·001 ) . Significance was not altered by diet , sex , medication or amount of weight loss . HDL-C increased on HPHchol ( + 0·02 ( sd 0·02 ) mmol/l ) and decreased on HPLchol ( - 0·07 ( sd 0·03 ) mmol/l , P < 0·05 ) . Plasma folate and lutein increased more on HPHchol ( P < 0·05 ) . These results suggest that a high-protein energy-restricted diet high in cholesterol from eggs  improved glycaemic and lipid profiles , blood pressure and apo-B in individuals with type 2 diabetes
