Q

Discuss the nutrition therapy from the 1920’s until today

A
  • 1920s: Carb restriction (max 100 g/day), fasting

36
Q

What are the two types of CHO counting?

A

Basic and Advanced

37
Q

A

When the patient is on insulin

38
Q

Discuss basic CHO counting

A

Encourages the inclusion of consistent amounts of CHO at meals and snacks

39
Q

Discuss advanced CHO counting

A

-Teaches patient who are on MDI or insulin pump how to match insulin to CHO

40
Q

What must we do before we begin CHO counting?

A

Determine the person’s base knowledge (healthy eating, perceived notions, basic nutrition concepts, understanding medication)

41
Q

Which concepts should be taught during CHO counting?

A
  • Rationale for counting carbs
  • Identify foods that contain carbs
  • Understand that many foods containing carbs are healthy, and these do not have to be overtly limited
  • Determine how much to eat per day
42
Q

How many carb servings per meal? How many g/serving?

A
  • 3-5 servings per meal

- 15 g per serving

43
Q

What would be an appropriate response to someone who believes cutting all carbs (i.e. ket/LCHF diets) will solve their diabetes?

A
  • It’s difficult to adhere to a low-carb diet
  • The glucose that we are consuming is NOT the only impact on our blood sugar, the endogenous production remains
  • Insulin is important for growth, protein synthesis and satiety
  • Caution with those w/ eating disorders who withhold insulin
44
Q

Key concepts to teach with advanced CHO counting?

A
  • The onset, action, peak and duration of insulin action
  • Difference between basal and bolus insulin

45
Q

How do we account for sugar alcohols in net carbs

A

Subtract 1/2 of them

46
Q

Discuss sugar alcohols

A
  • Only about 50% are absorbed, less kcals
  • There may be GI side-effects when more than 10 g/day is consumed
  • Sometimes not listed on nutrition facts, difficult to account for
  • Often found in processed foods, special diabetic foods which are not necessarily what we want patients eating
47
Q

Where are hidden carbs?

A
  • Breading on meat
  • Cornstarch mixed in dishes and soups
  • Pasta sauce
  • Croutons in salads
  • Salad dressing
  • Ketchup
48
Q

What do studies show about patients and their ability to carb count after being counselled by a dietitian?

A

Almost as accurate as a computer program as estimating

49
Q

What do studies show about patients ability to carb count, when they are not offered a revision by a dietitian?

A

Up to 20% error of CHO counting within the meal

50

  • More variety in food
  • Does not raise blood glucose
  • Does not contain calories
  • Can help avoid dental caries, while still enhancing
64
Q

How does artificial sweeteners allow for more variety in food?

A

-Enables people who are CHO, sugar or kcal conscious to take in a wide range of foods that they would either not be allowed to eat or could only eat in such tiny amounts that they were not satisfying

65
Q

What are some health concerns of artificial sweetners?

A
  • Can be associated with cancer (cellular damage)
  • Can cause bloating
  • Can be associated w/ hyperTG an GI symptoms

A
  • Protein to slow digestion

- May reduce chance of having low blood sugar during the night and/or may improve morning blood sugars

68
