¢ To delay or prevent complications associated with diabetes
¢ To provide specific guidelines for different stages in the lifecycle
¢ To promote self-care by providing the necessary knowledge, skills, resources and support
¢ To encourage overall health by practical instructions in optimal nutrition

Q

What is the order of Nutritional management of hyperglycemia in type 2 diabetes provided by CDA?

A

Clinical assessment
Lifestyle intervention by Registered Dietitian
-
Initiate intensive lifestyle intervention or energy restriction + increased physical activity to achieve/maintain a healthy body weight
-
Provide counselling on a diet best suited to the individual based on preferences, abilities, and treatment goals using the advantages/disadvantages listed below
-
If not at target
-
Continue lifestyle intervention and add pharmacotherapy
Timely adjustments to lifestyle intervention and/or pharmacotherapy should be made to attain target A1C within 2 to 3 months for lifestyle intervention alone or 3-6 months for any combination with pharmacotherapy

Q

What is glycemic index?

A

Scale 0-100 compared to glucose standard

  • Area under the curve (AUC) in blood glucose response of a given food compared to standard (glucose or white bread) for the same content in g CHO.
    Ex: 200 g cooked pasta (50 g CHO) vs. 50 g glucose or 100 g white bread (50 g CHO).
    GI= AUC pasta / AUC glucose or white bread X 100= 46

What is the target fat for diabetic patients?

A

18
Q

¢ Concern with chronic kidney disease (CKD)
- No more than 0.8 g/kd/d

Type 1
- decrease calories: NO
- Improve insulin action (sensitivity) –> Seldom important:
β-cells are inactive and no IR

- Consistent intake of kcal, CHO, pro, fat –> Important (conventional Tx) Not critical (intensive Tx)

Type 2

  • decrease calories: YES
  • Improve insulin action (sensitivity) –> very important
  • Increase frequency of feedings –> not usually
  • Consistent intake of kcal, CHO, pro, fat –> Better but not critical
37

How important is consistent ratio of CHO, pro, fat/meal in T1DM and in T2DM?

A

T1DM

  • Very important (conventional Tx)
  • Not critical (intensive Tx)

T2DM
- not crucial

Q

How important is consistent timing of meals in T1DM and in T2DM?

A

T1DM
- important (conventional Tx)

T2DM
- not crucial

Q

How important is extra food for unusual exercise in T1DM and in T2DM?

A

T1DM

  • Yes (conventional Tx)
  • Variable (intensive Tx)

T2DM
- Not usually

40

How important is during illness, provide CHO (with meds and close monitoring) in T1DM and in T2DM?

A

T1DM
- To prevent ketosis (insulin needs may be higher than usual)

T2DM
- To prevent HHS

41
Q

How important is use of food to treat, prevent hypoglycemia in T1DM and in T2DM?

A

T1DM
