When the food source is almonds, researchers have found that a calorie labeled is not the same as a calorie absorbed and digested at the University of Toronto. The finding should help ease concerns that almonds contribute to weight gain. The view that almonds make weight again persist despite the widely recognized benefits of it such as protein, mineral, and vitamin.
According to John Sievenpiper, principal investigator on the study and at the Temerty Faculty of Medicine an associate professor in the departments of nutritional sciences and medicine “Nuts have generally been thought of as healthy the last two decades, but the messaging around nuts has often come with a disclaimer that they are high in fat and energy.”
The findings were published recently in the journal Mayo Clinic Proceedings. After digestion, the researchers found that about 20% of the calories derived from fat in almonds remained unabsorbed, which they observed in stool samples. Among the study participants, that translated to about two percent less energy absorbed from the diet overall.
In a daily diet of 2,000 to 3,000 calories, a person eating the same amount of almonds would absorb 40 to 60 calories less than predicted by Atwater factors, on which many food labels are based. Over a year, that could result in weight loss of up to 2.9 kilograms, assuming no compensation in the form of decreased energy expenditure or increased intake.
Participants in the study did not gain weight and in the majority of high-quality trials that is consistent that measure nut consumption and weight gain. A randomized crossover trial was used by the researchers to study 22 women and men with high cholesterol. A series of three-month-long dietary interventions were undergone by them separated by a week-long washout period. They consumed an NCEP Step-2 diet. The three dietary interventions were full-dose muffins, full-dose almonds, and half-dose almonds plus half-dose muffins. The amount of protein, fiber, and fats nutritional makeup of the muffins matched the almonds.
According to Stephanie Nishi, a doctoral student in nutritional sciences at the time of it, the study assessed people with high cholesterol and those who have higher chances of cardiovascular disease. In this population before that has not been done and it’s important because this group gets many messages to eat more nuts as it is good for heart health.
