Researches at the International Tree Nut Council, a non-profit and non-governmental organization that dedicates themselves to supporting nutrition research and education around tree nuts and associated products, have studied two new meta-analyses involving tree nuts and their effects on diabetes and metabolic syndrome.
Tree nuts include: Almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts.
The first study, which was published in the British Medical Journal Open, looked at how tree nuts can affect metabolic syndrome (MetS). This study included 47 randomized control trials with 2200 people who were healthy or had MetS criteria, dyslipidemia (elevated levels of blood cholesterol and/or triglycerides) or type 2 diabetes. The study was able to find that the consumption of tree nuts, around 100 grams a day, significantly decreased triglycerides and fasting blood glucose.
The second study in the PLOS ONE article focused its efforts on the effect tree nuts had on glycemic control in diabetes. It included 12 randomized clinical trials with 450 participants and compared those that had a diet which emphasized tree nuts to those that didn’t according to their HbA1c (a marker of longer term blood sugar control), fasting blood glucose, fasting insulin and insulin resistance levels. Results again found that tree nuts of 100 grams a day incorporated into the diet has significant decreases in HbA1c and fasting blood glucose levels.
These studies back up the facts that by incorporating tree nuts into daily consumption and diets it will have an overall metabolic benefit that will improve individual’s with type 2 diabetes risk factors in terms of metabolic syndrome, and glycemic control.
