Q

The Nurses’ Health Study showed all the following findings except:

A. Consumption of processed meat five or more times per week was associated with an increased risk of diabetes.

B. A vegan diet was associated with a 48% reduction in diabetes medications.

C. Overweight or obesity was the single most important predictor of diabetes.

D. Abstinence from alcohol was associated with a significantly increased risk of diabetes, even after adjustment for BMI.

A

B is false.

B is not from Nurses Health study, it’s from Barnard ND et al 2006 A low-fat vegan diet improves glycaemic control.

A is from Nurses health study 8 year follow up

C 16-year follow up from nurses health

D 16-year follow up from nurses health, lack of exercise, a poor diet, current smoking, and abstinence from alcohol use were all associated with a significantly increased risk of diabetes, even after BMI adjustment.

Q

Insulin resistance is dependent upon which factors?

A. Changes in microbiome

B. Epigenetic factors

C. Diet and Lifestyle factors

D. B and C

Answer is D (that is, options B and C)

Changes to microbiome can cause dysbiosis (microbiome imbalance) which decreased short-chain fatty acids production like butyrate which assist in blood sugar management, but insulin resistance is not dependent on it.

Q

Regarding atherosclerosis, atherosclerotic plaques and cholesterol, which is incorrect?

A. Plaque progression ceases with total cholesterol < 150mg/dl (3.879mmol/L).

B. Hypercholesterolemia is the only direct risk factor for atherosclerosis.

C. Cigarette smoking, hypertension, DM, inactivity, and obesity directly produce atherosclerotic plaques.

D. At Serum cholesterol between 90-140mg/dl (2.327 -3.620mmol/L) plaque formation is not seen.

E. LDL at 50-70mg/dL (1.293- 1.810) is ideal.

A

C.

Hypercholesterolemina is the only DIRECT risk factor for atheroscleoris. There is no evidence that cigarette smoking, hypertension, DM, inactivity, and obesity directly produce atherosclerostic plaques, but if they do, it is indirect.

C. Myristic acid is harmful and is found in dairy (cheese, butter, milk), coconut oil, palm kernel oil; and in small amounts in nutmeg and palm oil.

D is correct because Lauric acid, a saturated fat in coconuts increases total cholesterol, both LDL and HDL.

E is incorrect because Lauric acid, stearic acid, palmitic acid, myristic acid are all SATURATED fat.

  4. Linolenic acid is anti-inflammatory.
  5. The relationship between omega 3 and omega 6 is simple and well understood.
A

E.

30
Q

Which one is incorrect?

  1. Hempseed in 3 tablespoons (33g) contain 15grams of protein which is higher in percentage compared to animal foods such as beef (grass fed, chuck roast) at 85grams yields of 22 grams of protein.
  2. Animal protein have more sulfur-containing amino acids which are metabolized into acidic metabolites. This requires the buffering system to leach out calcium from the bones as a buffering substate which long term contributes to good strong bones.
  3. Soy protein, wheat gluten and wheat flour have ileal digestibility at 90% similar to animal based proteins which have 95% ileal digestibility.
  4. Saturated fats and transfat in the diet are generally better replaced by monounsaturated fats and polyunsaturated fats from plants and seafoods.
A

B.

According to T. Colin Campbell, a more acidic diet requiring buffering to alkalinize causing calcium to leach out into the blood out of the bones can cause poor bone strength long term.

  3. Antioxidant supplements do not seem to reduce cancer risk but whole foods do.
  4. There is clear evidence that pancreatic cancer, ovarian cancer, and endometrial cancer have lowered risk with high fibre plant-based diet.
A

D.

There is NO clear evidence yet for nutrition associations with pancreatic, ovarian and endometrial cancers. See pp 139
Obesity is the most common nutritional problem correlating western diseases and lifestyle. See pp 140.

A low-fat vegan diet is superior to the American Diabetes Association Diet regarding Type 2 Diabetes. See pp 141.

Antioxidant supplements do not seem to reduce cancer risk but whole foods do. pp 139

32
Q

Regarding Nutritional prescribing and behavioural change from patients which ONE of the following is incorrect?

  1. Patients make more changes when health providers ask for more behavioural changes from their patients.
  2. Patients do not accept dramatic changes.
  3. Optimal therapeutic dosing must be prescribed in terms of lifestyle intervention.
  4. Nutritional prescription can be used to prevent and treat some specific chronic conditions.
A

B.

The more behavioural change providers ask for, the more changes patients make. It’s not necessary to prescribe smaller changes that may not create an effect. Dramatic change is more acceptable to patients. As lifestyle medicine prescribers we need to prescribe lifestyle medicine treatment at the optimal therapeutic dosages.
