A deficiency of which mineral is associated with infant mortality, cretinism and goitre?

Zinc
Iodine
Copper
Magnesium
Manganese

Correct Answer

A. Iodine

Explanation

A deficiency of iodine is associated with infant mortality, cretinism, and goitre. Iodine is an essential mineral required for the production of thyroid hormones, which are crucial for the development and functioning of the brain and nervous system. Infants born to mothers with iodine deficiency are at a higher risk of mortality and developmental issues. Cretinism is a condition characterized by stunted physical and mental growth, which is commonly caused by severe iodine deficiency during pregnancy. Goitre, on the other hand, is the enlargement of the thyroid gland due to iodine deficiency.

Which of the following has the lowest content of iron per 100g?

Meat
Eggs
Milk
Green leafy vegetables
Legumes

Correct Answer

A. Milk

Explanation

Milk has the lowest content of iron per 100g compared to the other options. While meat, eggs, green leafy vegetables, and legumes are generally good sources of iron, milk is not a significant source of this mineral. Iron is essential for the production of red blood cells and plays a crucial role in transporting oxygen throughout the body. However, milk is not typically consumed for its iron content, and individuals looking to increase their iron intake may need to consider other food sources.

Which of the following statements regarding calcium is NOT correct?

It is mostly stored in bones and teeth
It aids blood clotting
It can cause kidney stones if taken in excessive quantities
It is released from bones when blood calcium is low
It prevents tooth decay if taken as a supplement

Correct Answer

A. It prevents tooth decay if taken as a supplement

Explanation

Calcium is mostly stored in bones and teeth, aids blood clotting, can cause kidney stones if taken in excessive quantities, and is released from bones when blood calcium is low. However, it does not prevent tooth decay if taken as a supplement. While calcium is important for maintaining oral health, it is not a direct preventive measure against tooth decay. Good oral hygiene practices such as regular brushing, flossing, and dental check-ups are essential for preventing tooth decay.

A glass of fruit juice consumed with wholegrain breakfast cereal will enhance the absorption of:

Zinc
Potassium
Sodium
Calcium
Iron

Correct Answer

A. Iron

Explanation

Consuming a glass of fruit juice with wholegrain breakfast cereal enhances the absorption of iron. This is because fruit juice, especially those high in vitamin C, helps to increase the bioavailability of iron from plant-based sources. Iron is an essential mineral for the body, playing a crucial role in oxygen transport and energy production. By improving iron absorption, consuming fruit juice with wholegrain breakfast cereal can help meet the body's iron requirements more effectively.

Which of the following statements regarding potassium is NOT correct?

Is the predominant mineral found inside cells
Is a major component of table salt and processed foods
Is involved in stimulating nerve and muscle cells
Is involved in controlling water balance
Deficiency accompanies dehydration

Correct Answer

A. Is a major component of table salt and processed foods

Explanation

Potassium is not a major component of table salt and processed foods. Sodium is the major component of table salt, while processed foods often contain high levels of sodium but not necessarily potassium. Potassium is primarily found inside cells and is involved in various physiological functions such as stimulating nerve and muscle cells and controlling water balance. Deficiency of potassium can occur with dehydration, but it is not directly related to the consumption of table salt and processed foods.

A typical Western diet provides ______ times the estimated physiological requirement for sodium.

5
10
15
20
25

Correct Answer

A. 5

Explanation

A typical Western diet provides 5 times the estimated physiological requirement for sodium. This suggests that the average Western diet contains significantly more sodium than what the body actually needs for normal functioning. Consuming excessive amounts of sodium can lead to various health issues, such as high blood pressure and increased risk of cardiovascular diseases. Therefore, it is important to be mindful of our sodium intake and make healthier dietary choices.

Which of the following has the lowest content of calcium per 100g?

Milk
Cheese
Butter
Sardines
Cabbage

Correct Answer

A. Butter

Explanation

Butter has the lowest content of calcium per 100g compared to the other options. While milk, cheese, sardines, and cabbage are all good sources of calcium, butter is not. Butter is primarily made up of fat and does not contain significant amounts of calcium. Therefore, it has the lowest calcium content among the given options.

The mineral content of food is dependent on the mineral content of the soil in which plants are grown or stock are grazed. This statement is particularly true for which of the following?

Iodine and selenium
Sodium and copper
Copper and selenium
Magnesium and iodine
Magnesium and copper

Correct Answer

A. Iodine and selenium

Explanation

The mineral content of food is dependent on the mineral content of the soil in which plants are grown or stock are grazed. This means that the levels of iodine and selenium in food are directly influenced by the levels of these minerals in the soil. Therefore, the statement is particularly true for iodine and selenium.

Which of the following food substances appear to promote the absorption of calcium?

Phosphates in cows milk
Phytic acid in husks of cereals
Oxalic acid in spinach and rhubarb
Lactose and other sugars
All of the above

Correct Answer

A. Lactose and other sugars

Explanation

Lactose and other sugars appear to promote the absorption of calcium. Calcium absorption is enhanced by the presence of lactose and sugars in the diet. Lactose, which is found in milk and dairy products, helps in the absorption of calcium in the intestines. Similarly, other sugars present in foods can also aid in the absorption of calcium. Therefore, consuming foods that contain lactose and other sugars can promote the absorption of calcium in the body.
