NTA NTA Functional Nutrition & Metabolic Health 2 — Questions and Answers
Question 1: Which macronutrient has the greatest impact on blood glucose levels and insulin response?
- Fat
- Protein
- Carbohydrates (Correct answer)
- Fiber
Correct answer: Carbohydrates
Carbohydrates are broken down into glucose and have the most direct and significant effect on blood sugar and insulin secretion.
Question 2: What is the significance of the gut microbiome in functional nutrition?
- It primarily produces vitamin D from sunlight exposure
- It influences digestion, immune function, metabolism, and mental health (Correct answer)
- It regulates thyroid hormone production
- It is responsible solely for breaking down dietary fat
Correct answer: It influences digestion, immune function, metabolism, and mental health
The gut microbiome plays a multifaceted role including nutrient metabolism, immune modulation, inflammation regulation, and production of neurotransmitter precursors.
Question 3: Which functional lab test would an NTA practitioner most likely recommend to assess adrenal function?
- Comprehensive metabolic panel (CMP)
- Salivary cortisol test (4-point diurnal pattern) (Correct answer)
- Fasting lipid panel
- Complete blood count (CBC)
Correct answer: Salivary cortisol test (4-point diurnal pattern)
A 4-point salivary cortisol test measures cortisol levels throughout the day and is considered the gold standard for evaluating adrenal rhythm and HPA axis function.
Question 4: What does 'food sensitivities' refer to in functional nutrition, as distinguished from a food allergy?
- An immediate IgE-mediated immune reaction causing anaphylaxis
- A delayed, non-IgE immune reaction that may cause chronic low-grade symptoms (Correct answer)
- A genetic inability to digest specific sugars like lactose
- An aversion to certain food textures or flavors
Correct answer: A delayed, non-IgE immune reaction that may cause chronic low-grade symptoms
Food sensitivities typically involve delayed IgG or IgA immune responses causing symptoms such as bloating, fatigue, or joint pain hours to days after consumption.
Question 5: Which of the following best describes the 'functional nutrition' approach to disease prevention?
- Treating symptoms with targeted supplements instead of pharmaceuticals
- Identifying and addressing root causes of dysfunction through individualized diet and lifestyle (Correct answer)
- Following standardized dietary guidelines for all clients regardless of health status
- Focusing exclusively on caloric restriction for weight management
Correct answer: Identifying and addressing root causes of dysfunction through individualized diet and lifestyle
Functional nutrition seeks to identify underlying root causes of health dysfunction and uses personalized dietary, lifestyle, and nutritional interventions to restore balance.
Question 6: Which fatty acid type is considered most pro-inflammatory when consumed in excess?
- Omega-3 fatty acids (EPA/DHA)
- Monounsaturated fatty acids (oleic acid)
- Omega-6 fatty acids (arachidonic acid) (Correct answer)
- Short-chain fatty acids (butyrate)
Correct answer: Omega-6 fatty acids (arachidonic acid)
Excess omega-6 fatty acids, particularly arachidonic acid, promote the production of pro-inflammatory eicosanoids and are linked to chronic inflammation.
