All 10 Questions
- An athlete consumes a meal of white rice and honey two hours before a race. Analyze the likely physiological response regarding her blood glucose and insulin levels.A) Stable glucose levels due to the high fiber content of simple sugars.B) A rapid glucose spike followed by an insulin surge, potentially causing a 'crash'.C) Delayed gastric emptying due to the complex carbohydrate structure.D) Increased fat oxidation as the primary energy source for the workout.
- Bioavailability refers to the proportion of a nutrient that is digested, absorbed, and utilized through metabolic pathways rather than just the total amount present in the food.A) TrueB) False
- To increase the absorption of non-heme iron found in plant sources like lentils, one should consume them alongside foods high in _____.A) CalciumB) Vitamin DC) Vitamin CD) Vitamin K

- Consider the role of 'Essential Fatty Acids' (EFAs) like Omega-3. Why does the human body require these specifically from dietary sources?A) They provide 12 calories per gram compared to the 9 in other fats.B) The body lacks the enzymes to synthesize them with double bonds at specific positions.C) They are the only fats that can be converted directly into glucose.D) They prevent the body from absorbing any saturated fats during digestion.

- A 'Complete Protein' source must contain all nine essential amino acids in proportions that match human requirements.A) TrueB) False
- Based on the thermic effect of food (TEF), which macronutrient requires the most energy for the body to process and digest?A) Saturated FatsB) Simple CarbohydratesC) ProteinD) Water
- While searching for a healthy snack, you find a product with 0g 'Trans Fats' but 'Partially Hydrogenated Oil' in the ingredients. This is a result of _____.A) Regulatory loopholes allowing <0.5g per serving to be rounded downB) The oil becoming healthy once it is partially hydrogenatedC) The removal of all cholesterol from the vegetable oilD) Natural fermentation processes in processed snacks
- Which of the following is a symptom of 'Micro-nutrient Malnutrition' often seen in populations with high-calorie but low-nutrient diets?A) Excess storage of fat-soluble vitaminsB) Hidden hunger (deficiency in essential vitamins/minerals)C) Superior cognitive function due to high sugar intakeD) Increased bone density from processed sodium
