A new Australian study has revealed that people with Type 2 Diabetes on a low carbohydrate, high fat (LC) diet do better than those on a high carbohydrate, low fat (HC) diet.
Researchers from the University of Adelaide and CSIRO shared this in the American Journal of Clinical Nutrition. The NHMRC funded study consisted of a randomised trial of 115 people with Type 2 Diabetes. It showed that greater than half of the participants on a low-carb, high-fat diet (LC), experienced 20% or more reduction in their anti-glycaemic medication score compared with one-fifth on the high carb, low-fat diet(HC).Diabetics on the low carb, high fat (LC) diet also managed to achieve further a twofold decrease in glucose variability markers.
This meant that they had greater glucose stability during the day, and, in fact, spent much less time in hyperglycaemia (an excess of glucose in the bloodstream, often associated with diabetes mellitus) than those on the HC diet.Interestingly, those on the LC diet also had larger reductions in triglyceride fats with favourable increases in HDL cholesterol (good cholesterol). At the same time, they achieved comparable reductions in LDL cholesterol (bad cholesterol).
The researchers proposed that reductions in LDL cholesterol for the participants on the LC diet could be the result of saturated fats being substituted for unsaturated fats. These results were also sustained over one year.Lead researcher Dr Grant Brinkworth from the CSIRO’s food and nutrition division further shared that evidence is starting to favour the low-carb, high-fat diet (LC) diet. He indicated this, referring to the revised American Diabetes Association guidelines. “They don’t specifically advocate a low-carb, high-fat diet but they acknowledge that these dietary patterns may have some merit.”
Australia’s national dietary guidelines are still focused on the benefits of a high carbohydrate diet, says Dr Brinkworth. Meanwhile, practising dieticians and diabetes educators still caution and say that evidence favours a plant based diet. This further reveals an evolution in thinking when it comes down to the best choice of diets for diabetics and those that are wanting to lead a healthier life.
It is well worth remembering if you are a diabetic and on prescribed medicines, not to make any drastic changes until you consult with your health professional. Having said that, it’s a diet and nutrition option well worth considering under the supervision of your health team.
We all know very well, how important well-controlled blood sugar and a healthy diet is for improved gut microbiome and optimal brain function. It’s great to see that a smarter diet can have such a profound and beneficial impact on our health and wellness.
