That is so interesting that you posted this, Alicia! I just asked about nutritional yeast flakes to a nutrition board I know (and trust) yesterday! I also read that it was an additional source of vitamin B-12 and is also even recommended in my vegetarian mom's handbook for many of the recipes. I was wondering if it caused an imbalance and if I would develop a yeast infection and the reply posters said that it wouldn't b/c it's dead yeast. I don't know, but I tend to err on the side of caution with these things. Personally I would prefer to use the supplements, but to each his own.

Thank you so much for providing this information.  I had many questions about nutritional yeast and B-12 and now they have been answered.   I will still used it sparingly (like in the stuffed shell recipe you provided) but I will now switch to supplements a couple of times a week.  Thank you for everything you do. 

Thanks so much for the information.  That really did help clarify the yeast confusion.  Thanks again Alicia. 

Very informative, as usual, thanks! I take a regular b-complex supplement, prescribed to me by my naturopath. I'll have to ask her about sublingual.... Thanks again!

i too just asked a friend why so many vegan recipes had "nutritional yeast" in them.   Im so glad you cleared this up.  Now i know why its being added and can omit if i choose.  thanks!

I love that recipe that you posted a while back for mac 'n cheese which uses nutritional yeast. I make it every once in a while and usually throw in a bunch of veggies like peas & carrots or broccoli and then bake it like a cassarole! Can't wait to see the new recipe later on! :)

I think Candida is one of the most difficult things to cure.  It is such a limited diet.  Fortunately there are so many good yeast free products out there now.  I think supplementation, such as oregano and taheebo are important too.  i was under the impression that sour dough is not recommended due to the fermentation?

Thank you for clearing up the b-12 dilemma. 

nutritional yeast ROCKS and is YUMMIE on popcorn......a dash agave too MmmmMMM :)

I use the nutritional yeast powder :) And I eat a lot of popcorn so I use it alot (made from scratch with grapeseed oil - good for high heat)......I sometimes put agea flakes in my food too......I like to get all my vitamins and minerals from foods...........I've been vegan for 5 years and NEVER felt better not to mention my allergies are down to nothing and athletically I am at top, rarely get ill and if I do my immune system is so strong that it kills the virus very early......On top of being vegan I ear healthily of course....otherwise my health results wouldn't be as they are.........

Someone once told me that Yeast isn't vegan. I found that hard to believe, however Yeast isn't the best for your body it still makes pizza crust super yummy so I won't write it off just yet.

Most B-12 Vitamins out there do come from Animals but there is a few products that have a Vegetarian B-12 which is produced differently. Check this out http://www.veganhealth.org/b12/vegansources 

The Companies that sell Nutritional Yeast are http://www.bobsredmill.com/nutritional-yeast.html
and http://bragg.com/zencart/index.php?main_page=product_info&cPath=15&products_id=127

Both are Vegetarian formulas, I've been researching because I don't want any animal products at all.
I don't think they come from animals but the word  vegetarian makes me wonder until I know more will let you know.

Sabrina, someone probably said that to you because yeast is a living organism.  a living, simple organism, just as plants are living organisms.  ive had many debates with an omnivore who tried to convince me that eating plants was just as bad as eating animals because they are all alive (obviously, we need to eat something!).  they used yeast as an example in this sort of "conversation".
i have actually had a Candida infection in my esophagus, so this is a very interesting post for me.  the doctors didnt do anything about it but put me on antibiotics for two weeks.  that was the end of the Candida issue.  they never explained to me how i got it, which worries me especially since it is a sign of immunodeficiency disorders.  thanks to alicia's post, i will try to avoid yeast products even more!  
i do realize that we need B-12, and sometimes i make a product called Mac-N-Chreese (pronounced "trees").  although it is processed, it is a good substitute for mac and cheese and is made with a lot of nutritional yeast.  i have it about once a month when im feeling too lazy to make a real meal.

To have good digestion what you really need is good bacterial balance in your gut.  The ratio should be 85% beneficial bacteria to 15% bad.  Most Americans have that ratio reversed.  Probiotics are hugely important in getting that balance back in order, I would say possibly more so that yeast.  Most people who have Candida issues are able to resolve it by adding high quality probiotics to their diet.  85% of your immunity is in your gut, so it's really important to take care of it.  A high quality organic probiotic superfood can be a great addition to your diet.

I watched a special on our local channel last night about GMO's. It was said that GMO's are in
ALL soybeans because the farmers bought the US government concept program in 1992.  Can you check with your people to find out if there are any brands of Tofu and Soy milk that are GMO free.  Thank you so much.   Superhero on Maui/Susan
