Question 1

Which concept in functional nutrition describes how genetic variants influence an individual's response to specific nutrients?

Accepted Answer

Nutrigenomics

Answer

Nutrigenomics studies how genetic variants affect the body's response to dietary components, enabling personalized nutrition recommendations.

Question 2

In functional nutrition, the '5R' gut restoration protocol begins with which step?

Accepted Answer

Remove

Answer

The 5R protocol (Remove, Replace, Reinoculate, Repair, Rebalance) starts with removing dietary irritants, pathogens, and stressors affecting gut function.

Question 3

Which methylation-related vitamin deficiency is most commonly screened in functional nutrition assessments to address elevated homocysteine?

Accepted Answer

Folate (B9)

Answer

Folate, along with B12 and B6, is critical for the methylation cycle that converts homocysteine to methionine; deficiency raises cardiovascular risk.

Question 4

The MTHFR C677T polymorphism reduces activity of which enzyme central to methylation?

Accepted Answer

Methylenetetrahydrofolate reductase

Answer

The MTHFR enzyme converts 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate needed for homocysteine remethylation; the C677T variant reduces this activity by up to 70%.

Question 5

Which dietary pattern is most frequently recommended in functional nutrition for reducing systemic inflammation and modulating the gut microbiome?

Accepted Answer

Mediterranean diet

Answer

The Mediterranean diet is rich in polyphenols, omega-3 fats, and fiber that collectively reduce inflammatory cytokines and promote microbiome diversity.
