Nutritional yeast

Nutritional Yeast is a deactivated yeast, often a strain of Saccharomyces cerevisiae, which is sold commercially as a food product. It is sold in the form of flakes or as a yellow powder and can be found in the bulk aisle of most natural food stores. It is popular with vegans and vegetarians and may be used as an ingredient in recipes or as a condiment.

History

The strain of S. cerevisiae used to produce nutritional yeast is grown on a medium of molasses and then harvested, washed, and dried with heat to kill or "deactivate" it. Because it is inactive, it doesn't froth or grow like baking yeast does so it has no leavening ability.

Nutritional Value

Nutritional yeast is a source of protein and vitamins, especially the B-complex vitamins. It is also naturally low in fat and sodium. Some brands of nutritional yeast, though not all, are fortified with vitamin B12. The vitamin B12 is produced separately from bacteria and then added to the yeast.

Culinary Uses

Nutritional yeast has a strong flavor that is described as nutty, cheesy, or creamy, which makes it popular as an ingredient in cheese substitutes. It is often used by vegans in place of cheese. It can also be used in many recipes in place of cheese, such as in mashed and fried potatoes, and also in scrambled tofu. Another popular use is as a topping for popcorn.

Health Benefits

Some studies have suggested that nutritional yeast may help to boost the immune system and can also help to improve digestion by replenishing the beneficial gut bacteria. However, more research is needed to confirm these potential health benefits.
