2. Question
2. Select the most appropriate response to this statement: Nutrigenomics is best defined as.
- The Body's response to the ingestion of a diet rich in phytonutrients
- Genetic Expression that is unique to each person
- The field of study which investigates the effect phytochemicals on gene expression

Question 3 of 6

3. Question
3. Which statement is correct?
- Curcumin is a well absorbed molecule with an anti-inflammatory effect
- b) Polyphenols are absorbed intact with little to no bacterial influence on availability
- c) Allicin is present in whole garlic cloves
- d) Polyphenols are poorly absorbed and require extensive metabolism via bacteria to render their metabolites more absorbable and bio-active
- e) The fatty acids Linoleic acid and Alpha-Linolenic acid are denoted as 18:3n-3 and 18: 2n-6 respectively

Question 4 of 6

4. Question
4. Which phytochemicals might be expected to have the most potent antioxidant effect in cells?
- a) Polyphenols

Question 5 of 6

5. Question
5. Which statement best characterises nutritional hormesis?
- a) Antioxidant containing molecules which help protect cells but are consumed in a high dose
- b) Moderate and chronic activation of stress-response mechanisms due to a long-term consumption of low dose hormetins
- c) Hormesis is a state where a low dose induces an antioxidant effect, and a higher dose increases this benefit
- d) Polyphenols are a small group of phytochemicals that are well absorbed and should be consumed in an optimal dosage for most benefit
- e) Phytochemicals are an extremely broad category of chemical and their molecular structure determines their absorption and biological actions
Correct

Incorrect
