Question 78

To determine the six main nutrients, we recall that the six essential nutrients are carbohydrates, protein, fat, water, vitamins, and minerals. Let's analyze each option:

• First option: Contains carbohydrates, protein, fat, water, vitamins, minerals – this matches the six main nutrients.
• Second option: Carotene (a vitamin A precursor), thiamine (a vitamin), sugar (a type of carbohydrate) – this mix is incorrect as it includes specific vitamins and a carbohydrate subtype instead of the main categories.
• Third option: Includes potassium (a mineral), vitamin A, fiber, cholesterol – these are not the six main nutrient categories.
• Fourth option: Includes fiber, cholesterol, phosphorus (a mineral) – these are not the six main nutrient categories.

Calcium is essential for bone health. A lack of calcium can lead to osteoporosis (a condition where bones become weak and brittle). Let's analyze each option:

• Heart Disease: Caused by factors like plaque buildup, not calcium deficiency.
• Cancer: Caused by genetic mutations, environmental factors, etc., not calcium deficiency.
• High Cholesterol: Related to diet (high in saturated/trans fats), genetics, not calcium deficiency.
• Osteoporosis: Occurs due to insufficient calcium (and vitamin D) leading to bone loss.

Answer:

A. Carbohydrates, protein, fat, water, vitamins, minerals
