TORONTO, Ont., July 12, 2001--Eating nuts every day could help control Type 2 diabetes and prevent its complications, according to new research from St. Michael's Hospital and the University of Toronto.
In the research, published online by the journal Diabetes Care, a team of researchers led by Dr. David Jenkins (University of Toronto Department of Nutritional Sciences; St. Michael's Hospital Risk Factor Modification Centre) reports that consuming two ounces of nuts daily as a replacement for carbohydrates proved effective at glycemic and serum lipid control for people with Type 2 diabetes. The article, entitled "Nuts as a Replacement for Carbohydrates in the Diabetic Diet," is available here: http://care.diabetesjournals.org/content/early/2011/06/02/dc11-0338.abstract
"Mixed, unsalted, raw, or dry-roasted nuts have benefits for both blood glucose control and blood lipids and may be used as part of a strategy to improve diabetes control without weight gain," said Dr. Jenkins, who also has appointments with St. Michael's Division of Endocrinology and Metabolism and the U of T's Department of Medicine. He also serves as Canada Research Chair in Nutrition and Metabolism.
Jenkins and his colleagues provided three different diet supplements to subjects with Type 2 diabetes. One group was given muffins, one was provided with a mixture of nuts including raw almonds, pistachios, walnuts, pecans, hazelnuts, peanuts, cashews, and macadamias, and one group was given a mixture of muffins and nuts.
Subjects receiving the nut-only supplement reported the greatest improvement in blood glucose control using the glycosylated hemoglobin (HbA1c) test. The nut diet subjects also experienced a reduction in low-density lipoprotein cholesterol (known as LDL, or "bad cholesterol"). The subjects provided the muffin supplement or mixed muffin-and-nut supp
