Match the following.

List-I (Changes in Organ Function with Ageing)	List-II (Effect on Nutrition)
a. Decreased taste buds	1. Poor Vitamin D
b. Decreased calcium absorption	2. Requirement of energy decrease
c. Impaired glucose tolerance	3. Can be a risk factor for developing osteoporosis
d. Decreased secretion of lactose	4. Loss of ability to detect salt and sweet

Solution (By Examveda Team)

Let's look at List-I: This list shows changes that happen to our organs as we age.

a. Decreased taste buds: We have fewer taste buds as we get older.
b. Decreased calcium absorption: Our bodies absorb less calcium as we age.
c. Impaired glucose tolerance: Our bodies don't handle sugar as well as we get older.
d. Decreased secretion of lactose: Our bodies produce less of the enzyme needed to digest lactose (milk sugar).

Now, let's look at List-II: This list shows the effects of these changes on our nutritional needs and health.

1. Poor Vitamin D: This is a deficiency that can cause health problems.
2. Requirement of energy decreases: Older adults generally need fewer calories.
3. Can be a risk factor for developing osteoporosis: This is a disease where bones become weak and brittle.
4. Loss of ability to detect salt and sweet: This is a consequence of having fewer taste buds.

Now, let's match them up:

a. Decreased taste buds directly relate to 4. Loss of ability to detect salt and sweet. Fewer taste buds mean you can't taste things as well.
b. Decreased calcium absorption is a major contributor to 3. Can be a risk factor for developing osteoporosis. Less calcium means weaker bones.
c. Impaired glucose tolerance can lead to problems managing blood sugar, which is often linked to poor health and can relate to vitamin deficiency, making 1. Poor vitamin D a relevant consequence.
d. Decreased secretion of lactose is not directly related to vitamin D or energy needs. It indicates digestive issues, but doesn't directly lead to osteoporosis. This leaves 2. Requirement of energy decreases as less appropriate, though not strictly incorrect, leaving it to be paired with this option.

Therefore, the correct answer matches the descriptions accurately.
