Answer :Jeffrey B. Blumberg, PhD, director of Tufts HNRCA Antioxidants Research Laboratory, checked on this study care.diabetesjournals.org/content/33/2/227 and answers: This reader should not be concerned about the impact of eating walnuts on blood sugar. The increase in this parameter was statistically significant only within the group eating walnuts-but not significant when compared with the control group not eating walnuts. It is the latter comparison that is most important and accounts for the day-to-day variability in blood sugar. Further, no significant change in insulin sensitivity or plasma A1c (glycosylated hemoglobin, a measure of long-term blood sugar levels) was noted. And, importantly, the walnuts provided a benefit on endothelial (vascular) function associated with a reduced risk of cardiovascular disease, the condition for which people with type 2 diabetes should be most worried (as they are at very high risk of cardiovascular disease).
