Parkinson's Parkinson's Nutrition and Lifestyle 1 — Questions and Answers
Question 1: Why should people with Parkinson's taking levodopa be cautious about high-protein meals?
- Protein enhances levodopa absorption
- Protein competes with levodopa for absorption in the small intestine (Correct answer)
- Protein causes dyskinesia directly
- Protein accelerates dopamine breakdown in the brain
Correct answer: Protein competes with levodopa for absorption in the small intestine
Large neutral amino acids from dietary protein compete with levodopa for transport across the intestinal wall and blood-brain barrier, reducing its effectiveness.
Question 2: Which dietary strategy is commonly recommended for Parkinson's patients to support gut health and reduce constipation?
- A low-fiber, high-fat ketogenic diet
- Adequate fiber intake with plenty of fluids (Correct answer)
- A high-sodium diet to maintain blood pressure
- Elimination of all dairy products
Correct answer: Adequate fiber intake with plenty of fluids
High dietary fiber combined with adequate fluid intake helps promote bowel regularity, which is frequently impaired in Parkinson's disease.
Question 3: Which vitamin deficiency has been associated with increased risk or severity of Parkinson's disease?
- Vitamin C
- Vitamin K
- Vitamin D (Correct answer)
- Vitamin B12
Correct answer: Vitamin D
Low vitamin D levels have been linked to a higher risk of developing Parkinson's disease and may influence disease progression.
Question 4: Which Mediterranean diet component is thought to have neuroprotective properties relevant to Parkinson's disease?
- Refined white bread
- Olive oil rich in oleocanthal (Correct answer)
- Processed red meat
- High-fructose corn syrup
Correct answer: Olive oil rich in oleocanthal
Oleocanthal found in extra virgin olive oil has anti-inflammatory properties that may help protect neurons relevant to Parkinson's pathology.
Question 5: What is the recommended approach to protein intake for a Parkinson's patient on levodopa who wants to maximize medication effectiveness?
- Eat all protein foods in the morning and at lunch, avoiding protein at dinner
- Consume protein mainly in the evening when levodopa is less critical (Correct answer)
- Avoid all protein completely
- Eat protein with every dose of levodopa to slow absorption
Correct answer: Consume protein mainly in the evening when levodopa is less critical
A protein redistribution diet shifts most protein intake to the evening meal, allowing daytime levodopa doses to work more effectively when motor function is most needed.
Question 6: Constipation in Parkinson's disease is partly caused by which autonomic nervous system dysfunction?
- Overactivity of the parasympathetic nervous system
- Reduced peristaltic activity due to autonomic degeneration (Correct answer)
- Excessive gastric acid secretion
- Hyperactive bowel contractions
Correct answer: Reduced peristaltic activity due to autonomic degeneration
Parkinson's disease causes degeneration in the enteric and autonomic nervous system, slowing gut motility and leading to constipation.
Question 7: Which beverage has epidemiological evidence suggesting it may reduce the risk of developing Parkinson's disease?
- Alcohol
- Caffeinated coffee (Correct answer)
- Fruit juice
- Carbonated soft drinks
Correct answer: Caffeinated coffee
Multiple epidemiological studies have found an inverse association between caffeinated coffee consumption and the risk of developing Parkinson's disease.
