Which group is most likely to be affected by undernutrition?

Undernutrition poses significant risks particularly for children and pregnant women due to their unique nutritional needs for growth, development, and overall health.

For children, adequate nutrition is essential for proper physical and cognitive development. Any deficiencies can lead to stunted growth, weakened immune systems, and long-term health issues. Pregnant women have increased nutritional requirements to support both their own health and the development of the fetus. Insufficient intake of essential nutrients during pregnancy can lead to complications such as low birth weight and developmental problems in children.

The other groups mentioned do not face the same risk of undernutrition. High metabolic rate individuals and those with balanced diets typically have sufficient intake to meet their nutritional needs, while individuals with regular access to food are less likely to experience undernutrition, as they can meet their dietary requirements consistently. Thus, children and pregnant women stand out as the groups most vulnerable to the effects of undernutrition.
