Q2: Are Daily Values the same for everyone?
A: No, Daily Values are based on average nutritional needs and may vary based on age, gender, activity level, and specific health conditions.
Q3: How are recommended daily values determined?
A: Recommended daily values are typically established by health authorities and nutritional experts based on scientific research about nutrient requirements for maintaining health.
Q4: Can Daily Value exceed 100%?
A: Yes, some nutrients in certain foods can provide more than 100% of the Daily Value, particularly with fortified foods or supplements.
Q5: Should I aim for 100% DV for all nutrients?
A: While 100% DV is a general guideline, individual nutrient needs vary. Some nutrients like fiber and vitamins should be consumed at or near 100%, while others like sodium and saturated fat should typically be consumed in lower amounts.
