LMBR Study Grp: Nutrition #4 Flashcards
Previously titled "Nutrition#fbgroup"
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.
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.
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.

Select the false statement in the following:
Advanced glycation end products:
- Levels can be influenced by the way a food is prepared.
- Are compounds formed when fat or proteins combine with sugar in the bloodstream.
- In high levels are associated with an increased risk of many diseases including diabetes, heart disease and Alzheimers.

Answer 4.
(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3704564/) - Information on AGE’s
Note on Answer 2: Although some references mention fats being implicated in the chemical reaction, the prinicipal pathway appears to be “a spontaneous reaction between an amino acid (protein) and a monosaccharide (simple sugar like glucose).” BR p134
Select the false statement in the following:
Fibre:
- Are carbohydrates that are not typically digested for energy.
- Promotes the growth of ‘good’ bacteria in the GI tract, which can improve gut and overall health.
- Daily recommended intakes of 25g for women and 38g for men are met by most Americans.
- Are found in plant foods, however refining processes can reduce levels.
- Can lower cholesterol, stabilise blood sugar and decrease the risk of colon cancer.
Answer 3.
p132
(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6124841/) a 2016 study estimates that 95% of adults and children in the USA are not meeting daily fibre targets
Which is true and the best correct answer regarding Advanced Glycation End Produces (AGES)?
A. AGES increase over time with increasing age, accumulating in the eye lenses and skin collagen.
B. Directly related to DM types 1 and 2, atherosclerosis, kidney disease and slow wound healing.
C. Build up leads to cell damage particularly in cells that have long life such as nerve and brain cells, renal collagen proteins, blood vessels and eye cells.
D. A and C.
E. ALL of the above.
E.

Which is true of AGES?
A. Associated with oxidative stress and inflammation. B. Formed by a spontaneous biochemical reaction between and an amino acid and a monosaccharide (eg glucose).
C. AGES form with high temperatures greater than 120 degrees C or 248 degrees F.
D. Moisture and lower heat cooking methods produce less AGES.
E. All of the above
E.

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.
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.

Which is incorrect about epigenetics?
A. Epigenetics are like “set switches” passed on from parents to their children.
B. Methyl groups from plant foods and B vitamins help improve methylation.
C. Obesity, heart disease and diabetes can be due to epigenetic changes.
D. Epigenetic changes occur in the DNA sequence components of genetic inheritance.
E. These non-DNA sequence components of epigenetics control gene expressions through histone acetylation, methylation of the DNA, micro-RNA and a growing number of other molecular changes.
D.
Epigenetics is the study of the non-DNA sequence components of genetic inheritance through DNA methylation, micro-RNA, histone acetylation, and growing number of other molecular changes.

The Dietary Guidelines for Americans have limitations in regard to the science for nutrition versus the political nature of the Dietary Guidelines for Americans. Which of the following are incorrect?
A. Nutritional recommendations are not affected by the food industry and the United States Dept of Agriculture (USDA)’s commission to promote US agricultural products.
B. Some experts question the conclusion and methodology of the Dietary guidelines due to the involvement of biased food industries in the creation of the guidelines.

D. The two foods that have limitations on the Dietary Guidelines for Americans are dairy and eggs. For example, yoghurt consumption may have a protective effect on lowering inflammation but cheese is pro-inflammatory with higher plasma inflammatory biomarkers.
A.
Numerous nutritional recommendations are affected by the food industry and the United States of Agriculture (USDA)’s commission to promote US agricultural products.
