  • 2. 

    What is the main function of fiber in the diet?

    • To build muscle

    • To add flavor

    • To aid digestion

    • To strengthen bones

    Correct Answer
    A. To aid digestion
    Explanation
    Fiber aids digestion by adding bulk to the stool, which helps keep bowel movements regular and can prevent constipation. It also helps to keep the gut healthy and can reduce the risk of digestive conditions like intestinal ulcers, hemorrhoids, and diverticulitis. Furthermore, fiber-rich foods can aid in weight management by making you feel fuller longer.

  • 3. 

    Which mineral is crucial for making red blood cells?

    • Iron

    • Calcium

    • Potassium

    • Zinc

    Correct Answer
    A. Iron
    Explanation
    Iron is crucial for the production of red blood cells, which carry oxygen from the lungs to the rest of the body. It forms part of hemoglobin, the protein in red blood cells that binds to oxygen. Without sufficient iron, the body can't produce enough healthy red blood cells, leading to iron-deficiency anemia, characterized by fatigue and weakness.

    Rate this question:

  • 4. 

    What does a deficiency in Calcium lead to?

    • Night blindness

    • Scurvy

    • Osteoporosis

    • Pellagra

    Correct Answer
    A. Osteoporosis
    Explanation
    Calcium is vital for maintaining strong bones and teeth. A deficiency in calcium can lead to osteoporosis, a condition where bones become brittle and fragile from loss of tissue, typically as a result of hormonal changes, or deficiency of calcium or vitamin D.

    Rate this question:

  • 5. 

    What is the glycemic index used to measure?

    • The fat level in food

    • The protein quality in food

    • The blood sugar impact of foods

    • The calorie count of food

    Correct Answer
    A. The blood sugar impact of foods
    Explanation
    The glycemic index measures the blood sugar impact of foods. It ranks foods based on how much they raise blood glucose levels compared to a reference food. Foods high on the glycemic index, such as white bread, cause rapid spikes in blood sugar, while low glycemic index foods, like whole grains, result in a slower increase in blood sugar. This is valuable for managing diets, especially for people with diabetes.

    Rate this question:

  • 6. 

    Which vitamin is necessary to help blood clot?

    • Vitamin K

    • Vitamin C

    • Vitamin B12

    • Vitamin D

    Correct Answer
    A. Vitamin K
    Explanation
    Vitamin K is necessary for blood clotting. It plays a key role in the activation of proteins and calcium essential in blood clotting. Without sufficient Vitamin K, the body cannot produce prothrombin, a critical blood-clotting factor, which could lead to bleeding problems and poor wound healing.

    Rate this question:

  • 7. 

    Which food is the best source of Omega-3 fatty acids?

    • Olive oil

    • Walnuts

    • Flaxseeds

    • Salmon

    Correct Answer
    A. Salmon
    Explanation
    Salmon is an excellent source of Omega-3 fatty acids, essential fats the body can’t make on its own. Omega-3s are crucial for brain function as well as normal growth and development. They have been shown to reduce inflammation and are important for cardiovascular health. Salmon contains more Omega-3s by weight compared to other foods typically high in Omega-3s like flaxseeds or walnuts.

    Rate this question:

  • 8. 

    Which vitamin is essential for vision and skin health?

    • Vitamin C

    • Vitamin A

    • Vitamin D

    • Vitamin E

    Correct Answer
    A. Vitamin A
    Explanation
    Vitamin A is essential for vision and skin health because it plays a crucial role in the formation and maintenance of healthy skin, teeth, skeletal and soft tissue, and mucus membranes. It is also vital for photoreception as it produces the pigments in the retina of the eye. Deficiency in Vitamin A can lead to impaired vision, particularly in reduced light (night blindness), and can cause skin issues.

    Rate this question:

  • 9. 

    How many calories are generally in one gram of fat?

    • 4 calories

    • 7 calories

    • 9 calories

    • 12 calories

    Correct Answer
    A. 9 calories
    Explanation
    There are approximately 9 calories in one gram of fat, making it the most calorie-dense macronutrient. This is important for dietary considerations where caloric intake needs to be monitored or adjusted. Fats are essential in the diet for the absorption of vitamins and providing energy, but due to their high caloric content, managing fat intake is crucial for maintaining a balanced diet.

    Rate this question:

  • 10. 

    What is the recommended dietary approach to reduce hypertension?

    • Increase sodium intake

    • Decrease potassium intake

    • Limit alcohol consumption

    • Increase fat consumption

    Correct Answer
    A. Limit alcohol consumption
    Explanation
    Limiting alcohol consumption is recommended to reduce hypertension, or high blood pressure. Alcohol can raise blood pressure to unhealthy levels and reducing its intake can have a significant beneficial effect on blood pressure. Moreover, alcohol reduction can also help manage calorie intake and reduce the risk of cardiac problems associated with high blood pressure.
