MODESTO, Calif., Nov. 14, 2011 /PRNewswire/ -- Today, World Diabetes Day, marks a global effort for awareness and education about the disease, which is expected to affect 8% of the global population by 2025. Adopting healthy eating habits is high on the list of recommendations for diabetes prevention and management.(1) In fact, multiple recent scientific studies have shown that a healthy diet that includes almonds every day shows promise in helping to improve certain risk factors for diabetes and maintain healthy blood sugar levels.

Most recently, a study published in Metabolism: Clinical and Experimental (Chen et al) demonstrated that incorporating almonds into a diet designed using the National Cholesterol Education Program (NCEP) step II dietary guidelines, which recommend less than 7% daily calories from saturated fat and less than 200 mg cholesterol daily, improved insulin sensitivity and lipid profiles in Chinese patients with type 2 diabetes.(2) Participants were recruited from the Endocrine Clinic of the Taipei Medical University Hospital, Taiwan. In this randomized crossover trial, 20 patients were assigned to either follow the control or almond diet for four weeks with a two week run-in and wash-out period. The almond diet was prepared by incorporating roasted, unsalted whole almonds into entrees, desserts or snacks to replace 20 percent of the calories from the NCEP step II diet. On average, participants consumed 56 grams (2 ounces) of almonds per day. The almond diet significantly decreased fasting insulin levels and fasting glucose levels, as well as total cholesterol (TC) levels, low-density lipoprotein (LDL) "bad" cholesterol levels and HDL (high-density lipoprotein) "good" cholesterol to TC ratio (HDL:TC) compared to the control diet.(3)

Limitations of this study include the sample size, length of the study, lack of an oral glucose tolerance test, and lack of hemoglobin A1c readings. The sample size for this study is considered small for a feeding study, so the results may not be extrapolated to apply to a larger population. Though the study showed that almond consumption lowered fasting blood glucose and insulin levels, in order to gauge the effect on insulin actions, an oral glucose tolerance test is needed, and none was administered. Lastly, because hemoglobin A1c is a measure of blood glucose readings over a 2-3 month period, it was not assessed in this study, as the study interventions only lasted for 4 weeks at a time.(3)

The results from this study support the findings of a similar study published in the Journal of the American College of Nutrition in June 2010. Data from this study suggested that consuming an almond-enriched diet may help those with prediabetes improve insulin sensitivity and maintain healthy levels of LDL "bad" cholesterol.(4) The study looked at the effects of consuming an almond-enriched diet on factors linked to the progression of type 2 diabetes and cardiovascular disease in adults with prediabetes. After 16 weeks of consuming either an almond-enriched or nut-free diet, both in accordance with American Diabetes Association (ADA) recommendations, the group that consumed an almond-enriched diet showed statistically significant improvements in measures of insulin sensitivity and clinically significant improvements in LDL-cholesterol levels, both of which are risk factors for heart disease and type 2 diabetes.(5),(6) Three caveats are that although study participants in both groups were instructed to consume the same amount of calories from carbohydrates, there was less self-reported carbohydrate intake among those in the almond group and although the diets were prescribed by registered dietitians, meals were not provided. The study's diet and activity level data were based on participant report.

"This new research suggesting that incorporating almonds into a healthy diet might help improve insulin sensitivity and maintain healthy LDL cholesterol levels is encouraging," says Jenny Heap, MS, RD, Health Professional Marketing Manager, Almond Board of California. "While further research is needed to confirm this relationship, it is especially helpful to understand that almond consumption might be beneficial in the early, or prediabetes, stage."
