A new study has found that a low-energy dense diet including daily potato intake promoted weight loss and reduced insulin resistance as effectively as beans, the study published in the Journal of Medicinal Foods says.
The findings from this eight-week randomized parallel design-controlled feeding study poke holes in a previous studies where potatoes were found to be a ‘low-quality carbohydrate’ while beans were a ‘high-quality carbohydrate’, a news release on the study said.
The study was completed by evaluating the effect of diets low in energy density (1 kcal/g) and high in either potatoes (potato) or pulses (bean) on blood glucose control in participants with insulin resistance.
It was found that both diets significantly reduced body weight, with no significant difference between diets. The bean diet lowered the insulinemic response to meals, and both diets lowered insulin resistance, the release noted. The bean diet significantly reduced total cholesterol; however, researchers note more research is needed. Both diets reduced LDL particle size and HDL cholesterol and participants were 87 to 88 per cent compliant with both diets.
“A reduced calorie diet that includes either potatoes or beans can result in weight loss and improves the insulinemic response in people with insulin resistance. Moreover, contrary to observations from epidemiological studies, potatoes do not adversely affect the glycemic response,” the release said.
