A good quality isolated, ultra-filtered whey protein shake powder should be ok to consume with your candida ... because the casein protein has been removed in the micro-filtration process. Casein is the protein in cow's milk that's most likely to trigger allergic symptoms. The whey protein is quickly absorbed in the small bowel, and so there's nothing to feed the yeasty beasties in the colon. Adding cream will of course add casein, which will delay absorption and potentially feed the yeast. Isolated soy protein would be acceptable too ... except it tastes like gaaccckkk! and often has added fructose and other sugars added to kill the taste.,
.. Read the labels carefully. Make sure there are no hidden sugars or glycerine. Most of the better lowcarb whey shake mixes are sweetened with sucralose (Splenda) or acesulfame potassium, which is not absorbed, and will not feed the yeast. Especially look for the term micro or ultra filtered ... or the term HBVP, which means Highest Biological Value Protein. These will have all traces of casein contaminant removed.
As for what else to drink ..... Dr. Crook says artificial sweeteners are ok in moderation. I'd be less worried about feeding the yeast than with consuming too much aspartame for other health reasons. As well, diet sodas contain citrate, and sometimes phosphoric acid. These can trigger allergy symptoms.
There are sugar-free syrups, zero carbs .. sweetened with splenda. Da Vinci, and I do believe Atkins makes these as well. You can choose a fruit-flavoured syrup to add to club soda or mineral water.
I've found lately that Perrier or sodium-free club soda, with a wedge of lemon or lime is more thirst quenching than sweet pop.
Oh, if aspartame doesn't bother you, then a very occasional serving of diet jello might be ok ... it's zero carbs, no sugar for the yeast ... it's just all the artificial colours and flavours added ..
