Explanation
A. Brittle hair is more associated with protein deficiencies or inadequate hydration rather than insufficient fiber intake.
B. Bleeding gums can be related to vitamin deficiencies (like vitamin C), poor oral hygiene, or gum disease but not primarily to inadequate fiber intake.
C. Constipation is a common consequence of inadequate fiber intake, as fiber helps add bulk to stools, promoting regular bowel movements.
D. Memory loss is not typically a direct result of insufficient fiber intake; it may be associated with various neurological or age-related conditions.
Correct Answer is B
Explanation
A. Lactose intolerance is more related to the absence of the enzyme lactase, commonly found in individuals who have a reduced ability to digest lactose (milk sugar), regardless of their dietary choices.
B. Vegan diets may lack sufficient iron intake as plant-based sources of iron (non-heme iron) are not as readily absorbed by the body compared to heme iron found in animal products. This can put vegans at a higher risk of iron deficiency.
C. Diabetes risk is influenced by various factors, including genetics and lifestyle, rather than specifically by following a vegan diet.
