Powder Organic Protein

Welcome @trip13, Interesting questions. I'm no expert but you can find a lot of studies on sugar and all of the associated bad effects it can have on us, especially if you have a medical condition. Here's some information on the topic.

"Avoiding processed foods and foods high in sugar means the body experiences fewer highs and lows of blood sugar, which helps to further reduce feelings of anxiety. Very simply put, a sugar rush can mimic a panic attack."

I drink a coffee flavored protein drink because I don't eat enough protein (my bad) so I try to supplement a little. My wife and I also use unflavored collagen powder mixed with our morning coffee to help with fingernails and skin. Doesn't seem to do much for my wrinkly old skin but it has helped my fingernails and my wife is sold on that because she used to really have brittle fingernails and she's noticed a difference.

Here's some info on the collagen and anxiety topic from a Weight Watchers article.
"Collagen and mood
As you’ll recall, collagen is missing the essential amino acid tryptophan. Tryptophan is a precursor to serotonin, a neurotransmitter that is responsible for—in addition many other important brain functions such as memory and learning—feelings of happiness and contentment. Ingesting collagen as your main form of protein can potentially lead to a deficit in tryptophan. A decrease in tryptophan results in lower serotonin levels and has the potential to cause feelings of anxiety, irritability, and depression (particularly if you already suffer from a mood disorder.)"

Have you discussed the supplements with your doctor or care team?

This post is very helpful to see that TRYPTOPHAN increases SERATONIN levels and something to be AVOIDED when I have diagnosis if Neuroendocrine Carcinoid Primary Tumor. Makes me suspicious of Thanksgiving Turkey as an example. Do we need to question our everyday diets and eliminate all foods containing or increasing SERATONIN??? A Oncology Nutritionist would be helpful; however, I can’t find one in my area. Does anyone have info?
