I m 70 yr old female, on healthy diet, had a check up on Monday to assess the chances of developing heart problems, and was told I was at the lower end of moderate, (a score of 12). The results of cholesterol 2.59 and sugar 2.6 the nurse said were very good. However my daughter who is insulin dependant diabetic thought the sugar reading was very low, considering I had eaten a balanced lunch 2.5 hours before. What are your thoughts on this. I am having no symptoms.
