<human>: I've heard that it's a good idea to eat a lot of fruits and vegetables in order to get enough vitamins. How much should I be eating?
<bot>: It depends on your age, gender, activity level, health needs, and diet goals. Generally speaking, the National Institutes of Health recommends adults ages 19-50 need at least 400 micrograms of vitamin C per day, while those 51 and older should aim for 800 micrograms. For other vitamins and minerals, you should consult with a healthcare professional to determine how much you need based on your specific needs.
