The Surprising Side Effects of Nutritional Yeast: Are There Hidden Dangers?
Nutritional yeast is a popular ingredient in vegan cooking that’s known for its cheesy, nutty flavor. It’s packed with essential nutrients, including B vitamins, protein, and fiber, making it a staple in many plant-based diets. However, despite its many health benefits, there are concerns about the potential side effects of consuming nutritional yeast. In this article, we’ll explore the surprising side effects of nutritional yeast and whether there are hidden dangers.
What is Nutritional Yeast?
Nutritional yeast is a deactivated yeast that’s often used in vegan and vegetarian cooking for its cheesy flavor and nutritional benefits. It’s made by growing Saccharomyces cerevisiae, a type of yeast, in a nutrient-rich medium like molasses or sugar cane. The yeast is then harvested, washed, and dried, leaving behind a yellow, flaky powder that’s often sold in bulk.
The Benefits of Nutritional Yeast
Nutritional yeast is known for its many health benefits. It’s a complete protein source, meaning it contains all nine essential amino acids that your body can’t produce on its own. This makes it an excellent protein source for vegans and vegetarians. It’s also rich in B vitamins, including B12, which is essential for healthy nerve function and red blood cell production. Additionally, it’s a good source of fiber and minerals like zinc, magnesium, and iron.
The Surprising Side Effects of Nutritional Yeast
While nutritional yeast is generally considered safe, there are some potential side effects to be aware of. Yeast, in general, can cause allergic reactions in some people, including skin rashes, difficulty breathing, and digestive issues. Additionally, nutritional yeast is high in purines, which can be a problem for people with gout or kidney stones. Purines break down into uric acid, which can build up in the joints and cause pain and inflammation.
Hidden Dangers of Nutritional Yeast
Beyond the potential side effects of consuming nutritional yeast, there are some hidden dangers to be aware of. Nutritional yeast is often fortified with synthetic B vitamins, which can be harmful in large amounts. For example, excessive amounts of vitamin B6 can cause nerve damage and peripheral neuropathy. Nutritional yeast is also high in glutamic acid, which can trigger migraines in some people.
The Bottom Line
While nutritional yeast is generally considered safe and comes with many health benefits, it’s important to be aware of the potential side effects. If you have a yeast allergy, gout, or kidney stones, you may want to avoid nutritional yeast or speak with your doctor before consuming it. Additionally, be mindful of the fortified B vitamins and glutamic acid in nutritional yeast and consume it in moderation. As with any food, it’s essential to listen to your body and pay attention to how you feel after consuming it.
