Healthier Sugar Debate in Bubble Tea

I was hanging out with my friend Little Johnny at a bubble tea spot. He always has his drink with white sugar, but I thought brown sugar was healthier due to its less processed nature and higher mineral content. Without Johnny noticing, I asked the barista to switch the sugars. When Johnny tasted it, he was confused and upset, explaining he preferred his bubble tea as it always was. Now he is mad and I feel guilty. Some say brown sugar is not actually healthier than white sugar. They are quite similar; the main difference is that brown sugar contains molasses, but the mineral benefits are negligible.
