Human Health and Nutrition Questions
-
5-10 g/1000kcal
-
10-40 g/1000kcal
-
40-50 g/1000kcal
B
Correct answer
Explanation
Weight loss diets typically contain 10-40 g of fiber per 1000 kcal to promote satiety and reduce energy density without compromising nutrient absorption. Extremely high fiber levels (above 40-50 g/1000 kcal) may decrease palatability and digestibility excessively.
-
macro-minerals
-
micro-minerals
B
Correct answer
Explanation
Micro-minerals, also known as trace minerals, are required by the body in very small amounts, typically measured in milligrams or micrograms per day. Macro-minerals, on the other hand, are required in larger quantities, usually grams per day.

Macro-minerals
D
Correct answer
Explanation
Macro-minerals are required by the body in relatively large amounts, ranging from several tenths of a gram to multiple grams per day. In contrast, micro-minerals (trace minerals) and vitamins are needed in much smaller, microgram or milligram quantities.
B
Correct answer
Explanation
There are six major classes of essential nutrients required by animals: water, carbohydrates, proteins, lipids (fats), minerals, and vitamins. Each class plays a distinct and vital role in maintaining life and supporting production.
D
Correct answer
Explanation
The human brain is highly glucose-dependent and consumes approximately 120 grams of glucose per day to maintain its metabolic functions.
D
Correct answer
Explanation
Fat provides 9 calories per gram. Therefore, 50 grams of fat multiplied by 9 calories/gram equals 450 calories.
-
2 litres
-
2 bottles
-
2 glasses
-
1 litre
A
Correct answer
Explanation
Health guidelines generally recommend that adults consume approximately 2 liters of water daily to maintain proper hydration.
-
17,000 more particles.
-
None. The water does not absorb plastic.
-
86,000 more particles.
-
155,000 more particles.
C
Correct answer
Explanation
Studies have shown that individuals who consume bottled water ingest significantly more microplastic particles annually compared to those who drink tap water.
D
Correct answer
Explanation
Chronic malnutrition is often defined by a caloric intake below the minimum threshold required for basic metabolic functions, which is generally cited around 2,000 calories for an average adult.
-
118/78
-
144/80
-
88/52
-
180/120
A
Correct answer
Explanation
A blood pressure reading of 120/80 mmHg is generally considered the standard for normal blood pressure, making 118/78 the closest and most accurate choice.
-
90/60
-
100/70
-
110/75
-
95/68
A
Correct answer
Explanation
Blood pressure readings of 90/60 mmHg or lower are generally classified as hypotension (low blood pressure). The other options represent normal or pre-hypertensive ranges.
-
mm Hg
-
mm O2
-
ppm
-
pounds per square inch
A
Correct answer
Explanation
Blood pressure is standardly measured in millimeters of mercury (mmHg). Other options like ppm or psi are used for different types of measurements.
