Restating the question to focus our analysis: Which of the following is a major nutritional concern for someone following a strictly vegan diet without supplementation?
Option 1: 'Excess calcium' — This is unlikely to be a major concern for a vegan without supplementation. Calcium excess is rare and would typically require excessive intake from fortified foods or supplements; normal vegan diets do not commonly raise calcium to harmful levels unless over-supplemented.
Option 2: 'Vitamin B12 deficiency' — This is the key concern. Vitamin B12 is primarily found in animal-derived foods, and strict vegan diets without fortified foods or supplements can lead to deficiency over time, risking anemia and neurological issues due to insufficient cobalamin intake.
Option 3: 'High cholesterol' — Vegan diets are often associated with lower cholesterol rather than high cholesterol, since they exclude dietary cholesterol found in animal products. While total cholesterol can vary, a major risk from a vegan diet is not typically high cholesterol.
Option 4: 'Protein overload' — Protein overload is not a typical issue for vegans; in fact, meeting protein needs on a vegan diet is usually manageable with a variety of plant proteins, and there is no common problem of excessive protein intake causing harm in standard dietary patterns.
Putting it together, the standout concern on a strict vegan without supplementation is the potential deficiency of Vitamin B12, since it is not readily available in plant foods and requires fortification or supplementation to maintain adequate stores. The other options mischaracterize common vegan nutritional risks or are not supported by typical dietary patterns.
