Lioness - I do not drink smoothies because I do not eat much fruit. I am on a no-sugar diet. Sometimes I eat a few berries. I eat my weight in vegetables. I cannot make a decent smoothie with the vegetables I'm allowed. I drink only water - so there would be nothing good to add to it. I used to drink smoothies all the time in the 1980s. But when I gave up sugar and no longer had fruit, I stopped drinking them. I dream of fruit but I just can't do it. I had a tiny bite of apple the other day - I didn't even enjoy it - and I'm covered with horrible hives. I am so allergic to sugar.
