Over 3 months, the subjects ate either:
1. A Paleolithic diet based on lean meat, fish, fruits, vegetables, root vegetables, eggs and nuts. (higher in protein & fat, lower in carbs) 2. A Diabetes diet designed in accordance with dietary guidelines (higher in carbohydrates & lower in fat)
The researchers looked at the variables below:
– changes in weight,
– waist circumference,
– serum lipids,
– C-reactive protein,
– blood pressure,
– glycated haemoglobin (HbA1c),
– areas under the curve for plasma glucose and plasma insulin in the 75 g oral glucose tolerance test.
The result: The patients eating a Paleo diet produced superior results (as below) compared to the patients eating a Diabetes diet based on dietary guidelines.
– lower levels of glycated haemoglobin (HbA1c)
– lower levels of triacylglycerol
– lower diastolic blood pressure
– lower body-weight
– lower BMI
– lower waist circumference
– and higher mean values of high density lipoprotein cholesterol
Over a 3 month study period, a Paleolithic diet improved glycemic control and several cardiovascular risk factors compared to a Diabetes diet in patients with type 2 diabetes.
This study does make you question why the American Diabetes Association still advocate and recommend type 2 diabetes patients to eat a diet low in fat and high in whole grains.
