Final answer:
Consuming too few kilocalories and/or nutrients that impair body function can result in undernutrition or malnutrition. This can lead to fatigue, weakened immune system, poor growth, and other health problems.
Step-by-step explanation:
Consuming too few kilocalories and/or nutrients that impair body function can result in various health problems. This condition is known as undernutrition or malnutrition, which can have serious consequences on overall health.
- Undernutrition refers to a lack of nutrients and insufficient energy supply, leading to issues such as fatigue, weakened immune system, poor growth and development, and in severe cases, life-threatening conditions like kwashiorkor and marasmus.
- Malnutrition does not distinguish between too many or too few nutrients, and it impairs overall health. Overnutrition, which is excessive nutrient and energy intake, can lead to obesity and other related health problems.
- Unbalanced nutrition, where there is an imbalance of specific nutrients, can also cause health issues. For example, inadequate intake of vitamin A can lead to blindness, while excessive intake can be toxic.
