Verified step by step guidance

1. Read each statement carefully and identify the key concept it addresses (e.g., folic acid, calcium, iron deficiency, vitamin D).
2. Understand the role of folic acid in food fortification. Research whether folic acid is added to replace fiber or for another purpose, such as preventing neural tube defects.
3. Review the nutritional content of green leafy vegetables to confirm if they are a good source of calcium. Note that while they contain calcium, bioavailability may vary.
4. Examine the prevalence of iron deficiency worldwide and confirm if it is indeed the most common nutrient deficiency.
5. Analyze the relationship between sun exposure, vitamin D synthesis, and the importance of dietary sources of vitamin D, especially in populations with limited sun exposure.
