1 gallon/month is 1 scoop of ice cream each on 5 or 6 days per week, or on average about 12–15 grams of sugar per day. It’s about the same amount of sugar you’d get from drinking one 12 oz can of soda every third day. If it’s the only sugary treat someone is eating, that’s still well below average for people in most industrialized countries. If combined with soda/candy/cake/cookies/cocktails/... then probably not such a good idea.
