After analyzing the results, they found that those who ate 3.3 servings of pasta per week, where one serving size was one-half cup of cooked pasta, lost about one-half kilogram over a 12-year period.
"The study found that pasta didn't contribute to weight gain or increase in body fat," lead author John Sievenpiper said in a statement. "In fact analysis actually showed a small weight loss. So contrary to concerns, perhaps pasta can be part of a healthy diet such as a low GI diet."
The scientists did note that their investigation only focused on low-glycemic index foods and that more research is needed to determine if weight loss is possible for other healthy diets that include pasta. However, they believe their findings are strong.
“In weighing the evidence,” Sievenpiper said, “we can now say with some confidence that pasta does not have an adverse effect on body weight outcomes when it is consumed as part of a healthy dietary pattern.”
