Finding ways to reduce some sugar seems to me to work better than trying to omit it. I cut down on sugar in my tea from 1 tsp. to 1/4 tsp., and these days, I enjoy it without sugar, although I admit to having a cookie with it. Part of cutting it from tea (I never put it in coffee) was drinking a better quality of tea.
I find a lot of recipes are too sweet for me, so I often cut back the sugar and do not miss it.
I roll my eyes when dieticians or nutritionists say that a piece of fruit can be equally satisfying. No. I like fruit, but it does not replace cake, quick breads, cookies, or candy. It is good to see an article such as this one that does not repeat that nonsense.
