Some poeple are also prone to the old world threat of gout and I am told acid foods like grapefruit, tomatoes, oranges can cause this to flare-up. Grapefruit is also a dieretic so those having to take water pills should also be careful I would think. Many are diebetic and eating a lot of fats I hear are not particularly good for that condition either. You can not eat it. BUT don't cheat for the 12 days on.
Juices are pure no cocktails -they have sugar of some type.
