The Benefits of Nutritional Yeast

The Benefits of Nutritional Yeast

Physical activity is a must for physical well-being, however, there is such a thing as overdoing it. The harder you push yourself during physical activity, the harder your immune system has to work. Initially, there is a positive correlation between exercise and an increased immune response, but if an athlete over trains or pushes too hard, immune system function can decline leaving the athlete more susceptible to infections and illness. This is where nutrition comes into play!

A recent study showed that by including a special fiber found in Brewer’s yeast and nutritional yeast, marathon runners were able to decrease their chance of developing a respiratory infection weeks after a marathon. Not only did their illness rates decline, but they also reported feeling better physically and emotionally versus those who were taking a placebo.

So what is nutritional yeast? Nutritional yeast is a deactivated yeast, often a strain of Saccharomyces cerevisia, that is sold as a food. You can find it at most health food stores as a yellow, flakey powder. It is widely used in vegan and vegetarian cooking as a cheese substitute and has a creamy, cheese-like flavor. You can even sprinkle it over some popcorn instead of butter, incorporate it into salad dressings or throw a spoonful into a Blast. It is a good source of B12, a variety of other B vitamins, fiber and trace minerals.

Including nutritional yeast into your daily diet can help enhance immune function, can decrease saturated fat intake by swapping out cheese and butter and is a good source of B-12, which can keep your energy levels high.
