Adipose tissue that is deposited deep within the abdominal cavity and surrounds the internal organs is known as which of the following?

A. Vitamin E is present in breast milk at levels generally sufficient for healthy, full-term infants. It functions as an antioxidant, protecting cell membranes from oxidative damage. Deficiency is very rare in breastfed infants unless there is a fat malabsorption disorder or premature birth with very low birth weight, as these conditions limit fat-soluble vitamin absorption. Therefore, routine supplementation is not required for most term infants.

B. Vitamin C is water-soluble and abundant in breast milk when the lactating mother has an adequate diet. It supports collagen formation, immune function, and antioxidant activity. Deficiency in breastfed infants is uncommon unless the mother’s intake is severely inadequate, which is rare in most populations.

C. Calcium is a critical mineral for bone and teeth development, and breast milk generally contains sufficient calcium to meet the needs of full-term infants. The infant’s calcium requirements are met even if maternal intake is moderate because the mammary gland actively regulates calcium content in milk. Deficiency in calcium is therefore not a common concern in healthy, exclusively breastfed infants.

D. Vitamin D is naturally present in breast milk in very low amounts, insufficient to meet the infant’s needs, particularly if sunlight exposure is limited. Vitamin D is essential for calcium absorption and bone mineralization. Without supplementation, breastfed infants are at risk for rickets, delayed bone growth, and skeletal deformities. Health organizations, such as the American Academy of Pediatrics, recommend daily vitamin D supplementation (typically 400 IU/day) for all exclusively breastfed infants.

A. Subcutaneous fat is stored directly under the skin and serves as an energy reserve, insulation, and padding. While it contributes to overall body fat, it is not located deep within the abdominal cavity and is less strongly associated with metabolic risk.

B. Essential fat is the minimum amount of fat necessary for normal physiological functions, including hormone production, nerve function, and reproductive health. Essential fat is distributed throughout the body and is not specifically concentrated around internal organs.

C. Brown fat is a type of adipose tissue rich in mitochondria that generates heat through thermogenesis. It is primarily found in newborns and small amounts in adults, usually around the neck and upper back, and does not accumulate around the abdominal organs.

D. Visceral fat is the adipose tissue located deep within the abdominal cavity, surrounding vital organs such as the liver, pancreas, and intestines. Excess visceral fat is strongly linked to increased risk of metabolic disorders, cardiovascular disease, insulin resistance, and type 2 diabetes. It differs from subcutaneous fat because of its location and its impact on health.
