Final answer:
A one-year-old with symptoms of scaly skin, coiled hair, and gingival bleeding is likely suffering from Vitamin C deficiency, which leads to a condition called scurvy. Scurvy can be prevented and treated with an adequate intake of Vitamin C found in fruits and vegetables.
Step-by-step explanation:
The vitamin deficiency suspected in a one-year-old with scaly skin, coiled hairs, and gingival bleeding is likely Vitamin C deficiency. This condition is known as scurvy, which can manifest with symptoms such as dry hair, gingivitis, bleeding gums, dry and scaly skin, slow wound healing, easy bruising, and compromised immunity. Scurvy is due to the inadequate intake of Vitamin C, which is crucial for the synthesis of collagen, contributing to the maintenance of skin, gums, and capillary walls. To prevent and treat scurvy, it is important to consume sufficient amounts of Vitamin C, which is abundantly available in citrus fruits, like oranges and lemons, as well as other fruits and vegetables such as tomatoes, peppers, and broccoli.
