Going Paleo? Study Says It's No Better Than Other Diets for Glucose, Insulin Regulation
There’s not much research available comparing the Paleolithic diet to other popular nutritional plans. A new study sought to scour existing data to see the Paleolithic diet’s effect on glucose and insulin regulation. The data showed no significant impact.
The Paleolithic diet might have health benefits, but a new meta-analysis of peer-reviewed research finds the diet does not appear to be any better than other diets when it comes to
The so-called “Paleo” diet has become a popular dieting trend in the United States and abroad in recent years. A 2018 study from the State University of New York
“However, the hunter—gatherer diet provides a higher amount of dietary fiber (up to 45–100 g per day) than a low‐carbohydrate diet,” writes corresponding author Jaroslav Walkowiak, MD, PhD, of the Department of Pediatric Gastroenterology and Metabolic Diseases at Poznan University of Medical Sciences, in Poland.
Other research
What Walkowiak and colleagues wanted to know is whether the diet might affect glucose and insulin levels, something that would be of significant interest to those with diabetes or pre-diabetes.
To investigate the question, the team reviewed the medical literature for randomly controlled trials that compared the Paleolithic diet to other dietary interventions. They zeroed in on studies that compared the effects of the diet on fasting glucose and insulin levels, HbA1c, homeostasis assessment of insulin resistance, and area under the curve for glucose and insulin (AUC 0-120) during the oral glucose tolerance test.
The search criteria netted 4 studies involving 98 subjects. After reviewing the data, Walkowiak and colleagues found the Paleo diet had no significant impact.
“The present meta‐analysis demonstrates that the Paleolithic diet did not differ from other types of diets commonly perceived as healthy regarding its effect (on the above-mentioned criteria),” Walkowiak and co-authors noted.
Despite the lack of a benefit over the other diets studied, the authors noted that the research has generally affirmed that low-carbohydrate diets can improve fasting glucose levels, particularly in patients with type 2 diabetes. Thus, while the Paleolithic diet might not have a statistically significant impact when compared to other low-carb diets, it may still have benefits over less-healthy diets. They write that longer-term studies would be needed in order to more concretely characterize the impact of such diets.
The new study aligns with a
