The review looked at how adding extra nutrients to food can help people in Europe get enough vitamins and minerals. Different countries have different rules about this. Kids eat more fortified foods than adults, but it's still not a big part of their diet. Studies show that adding nutrients to foods like breakfast cereals can help people get enough folate, vitamin D, and riboflavin. Some worry that too many added nutrients could be harmful, but most people don't eat enough fortified foods to be at risk. Overall, adding extra nutrients to food can help improve vitamin and mineral levels in European populations without causing harm.
