Victoria, they are different.  It depends on your needs which one is more appropriate for you at any given time.  I was hoping someone else would type in the info from the KAL container

So Vicki, what needs would each one fill differently

typebase has brewers

but no nutritional

John,
found a quote by Heidi on NY.)

Quoted Text

Nutritional yeast itself is perfectly fine on Candida diets. First, it's not a live yeast (like baker's yeast). Second, Candida albicans is a totally different organism from the baker's yeast and brewers' yeast critters -- it's called 'yeast,' but it's worlds apart. I think nutritional yeast is a very helpful supplement for intestinal dysbiosis, in fact.

Nutritional yeast has the same values as brewer's yeast for blood type diet use.  

Thanks Lola and Vicki,
I was curious about the nutritional content of the two.  I believe that you (Vicki) had said that they contained different amounts of vitamins?

yes me too

I've modified my post with info from both.

Hey,
Thanks, Vicki for taking the time to do that for us!  Not that Laura and I twisted your arm or anything!    

A lot of the ratios seem similiar, since the serving size is bigger for the BY than the NY.  So, it looks like the NY is "enriched" with some B vits and the BY is just naturally showing what occurs in it.

Chromium and copper levels are different, for instance.

What is being compared here is not actually the difference between "brewer's yeast" and "nutritional yeast," but merely the difference between two brands of Saccharomyces cerevisiae.  Lewis chooses to use the traditional term "brewer's yeast" and KAL chooses to use the newer term "nutritional yeast."

The main difference between the two products, as has already been noted, is that the KAL product has been fortified with added B vitamins and the Lewis product has not.  There may also be some differences in how they were grown.  But these differences are not what separates "brewer's yeast" from "nutritional yeast" -- those are merely two different names for S. cerevisiae.

Think two cans of beans:  Brand X Chickpeas have salt added and Brand Y Garbanzos do not, but this does not mean that "chickpeas" contain more sodium than "garbanzos," because those are simply two different names for Cicer arietinum.

By the way, Lola may already have noticed that the yeast's species name, cerevisiae, looks a heck of a lot like "cerveza" -- the Spanish word for beer!

Here are links to the two manufacturers' web pages for their respective yeast products, just in case you want to see for yourself that they're both Saccharomyces cerevisiae:

Lewis Laboratories Brewer's Yeast: http://www.lewis-labs.com/products/brewersyeast.htm

KAL Nutritional Yeast: http://www.nutraceutical.com/search/view_product.cfm?product_index=38000

Note also that Lewis says their product "is not derived from the brewing process" and KAL describes theirs as "primary grown for human consumption" -- again, two different ways of saying the same thing.

The main difference is that one is grown on beets and one is grown on molasses.

Quoted from Vicki

The main difference is that one is grown on beets and one is grown on molasses.

Maybe this would be the reason the tastes are different and different people prefer one instead of the other.

And thanks, Carol, for digging up that info on yeast.  This is an informative discussion.  I like hearing all these bits of knowledge from you all!

thanks Carol! )

salud!!!  ''hick!!''

I ADORE, ADORE nutritional yeast AND I'm a secretor, BUT I'm a secretor whose body seems to behave more like a non-secretor in that I am grain and sugar sensative.

I just looked at KAL's website and was amazed to see that all this time that I have using a slightly different product....imported yeast...it's different than the nutritional yeast.  The last time I looked for the flakes at WF they were out so I bought the ones in the yellow and green can, thought it was the same but now I'm not so sure.  In any case, I've been putting it on my eggs in the morning and I like it.  Does anyone know whether there's any reason not to use the imported nut. yeast as oppossed to the yeast flakes?
Jane

Jane -- According to KAL's web site, the Imported Yeast is "Primary grown Unfortified Imported Nutritional Yeast (Saccharomyces cerevisiae)."  So it's the same species as their Nutritional Yeast Flakes, but it does not have any extra vitamins added.  If I'm reading the microscopic photo of the label correctly, it's grown on molasses, the same as the flakes.

I have used this product in the past, and as I recall, it's a powder rather than flakes.  If you want to use it in a recipe that calls for yeast flakes, use only about half as much, because the powder is more compact.

It has less of certain vitamins than the flakes do, but that's because the vitamins have been added to the flakes -- which I don't feel is the same thing as eating a food that naturally contains those vitamins, more like taking a vitamin pill.

Since you like the taste, I can't think of any reason not to use this product.

HI,  I've added Brewer's Yeast to my home made mayonnaise along with other spices for a salad dressing.  I don't store it that way but add it just as I'm making my salad.  Do you know if the brewer's yeast would holds its nutritional value if I did store this "salad dressing" in the refrigerator?  Is it only heating that decreases nutritional value?
Molly

I believe it is heat, light and air that would affect its nutritional value.

I just checked my cabinet and it is Lewis Labs Brewer's Yeast that I have at the moment.  I put it in my morning protein shakes several times per week.

I like both NY and BY.

wellll, what can I say? I love it! It is cheesy. I sprinkle it on toast with ghee...heaven. I've been eating it since I was a barefoot hippy back in the day! My kids loved it too.

After trying unsuccessfully for a couple of years to figure out what is causing flatulence, I tried eliminating the NY from my morning fruit smoothie.  Instantly the difference could be felt!  Absolutely amazing.  
I really love Nutritional Yeast, and I'll try it later on some non-fruit foods.  I'm hoping that is why it was causing the gas.

yes, Victoria, it can cause gas, but if you start getting used to it slowly, you can bump up the emount slowly...and I never take it with anything sweet...try it on your rice cracker with tahini or ghee......
