Nutritional Value of Brewer's Yeast

Brewer’s yeast is an inactive one-celled fungus (saccharomyces cerevisiae) and is a by-product of beer-making.

The term “nutritional yeast” is sometimes applied to brewer’s yeast, but here, we refer to the by-product of beer-making as brewer’s yeast.  Nutritional yeast can be grown on sugar beets, rather than on grain, and will have different nutrient values.

Both kinds of yeast are inactive, meaning that the live enzymes are destroyed in the heating process and the yeast will not ferment.  You cannot use brewer’s yeast to raise bread.  Rather, we use this yeast as a nutritional supplement; as such, it provides several valuable vitamins and minerals.

Brewer’s yeast is considered to be a prebiotic and probiotic useful for good digestion, as well as being rich in chromium, which is helpful for blood sugar regulation.  It is thought to strengthen the immune system.

The average adult dosage is two tablespoons daily.  Work up to that gradually as it may take time to adjust to the flavor, and you can monitor any side effects.  You can add it to food, blend it into a smoothie, or stir into water. Nutritional yeast grown on sugar beets will be gluten-free but brewer’s yeast may contain gluten.
