In a study, scientists compared the microbiomes of poorly nourished and well nourished infants and young children. Gut microbes were isolated from faecal samples of malnourished and healthy children. The microbiome was "immature" and less diverse in malnourished children compared to the better developed "mature" microbiome found in healthy children of the same age. According to some studies, the chemical composition of mother's milk has shown the presence of a modified sugar (salivated Oligosaccharides). This is not utilized by the baby for its own nutrition However, the bacteria constituting the infant's microbiome thrive on this sugar which serves as their food. Malnourished, mothers have low levels of this sugar in their milk. Consequently, the microbiomes of their infants fail to mature. That in turn, leads to malnourished babies.
Which one of the following is the most logical, rational and crucial inference that can be derived from the above passage?
Correct Option (D):
The passage establishes a direct link between the maturity of an infant's gut microbiome and its nutritional status, attributing malnutrition to an immature and less diverse microbiome. It further explains that sialylated oligosaccharides in mother's milk are vital for microbiome development, and their deficiency in malnourished mothers' milk leads to infant malnutrition. This scientific understanding of how gut bacteria influence infant nutrition and health, particularly through maternal factors, provides a basis for public health interventions. Consequently, research elucidating such benign effects of gut bacteria on nutrition holds significant implications for policy formulation concerning maternal and child health, nutrition programs, and dietary guidelines.
Incorrect Options:
Option (A): The passage identifies a causal relationship between gut bacteria and malnutrition but does not provide any information or inference regarding the treatability or untreatability of such conditions. The focus is on the mechanism, not on therapeutic limitations.
Option (B): While the passage underscores the importance of a mature microbiome, it does not suggest or discuss microbiome inoculation as a proposed solution or intervention. This inference extends beyond the information presented in the passage.
Option (C): The passage highlights the critical role of mother's milk and its specific components for infant microbiome development. It notes a deficiency in the milk of malnourished mothers. However, it does not advocate for replacing mother's milk with fortified dairy milk. The logical implication is to address the underlying maternal nutritional deficiency or enhance the mother's milk, rather than substituting breastfeeding.
