Aside from playing a major role in breadmaking and in breweries, yeast is also a surprisingly rich source of nutrients.
Yeast can be defined as a type of fungus (Saccharomyces cerevisiae) that converts carbohydrates to carbon dioxide and alcohol via the fermentation process. When it comes to making bread, the carbon dioxide produced by yeast makes the bread fluffy while the alcohol evaporates, during the baking process.
Yeast also contains a variety of nutrients but it should be noted that the amount of yeast in bread is minimal. This means you are unlikely to obtain a significant amount of nutrients by eating baked goods. Food products like brewer’s yeast and nutritional yeast are non-living yeast so they don’t cause dough to rise. Other than nutritional and brewer’s yeast, there are other food products that contain yeast extracts, which work as great sources of nutrients.
- Brewer’s yeast is a by-product of brewing beer and contains high levels of chromium which may lower blood sugar levels.
- Nutritional yeast is popular with vegans as a replacement for dairy products due to its ability to thicken
- Other than chromium, brewer’s yeast contains an array of B-complex vitamins, selenium and protein.
- Tyramine is a chemical in brewer’s yeast that can cause high blood pressure, when consumed in large amounts. Medication to treat depression stops the body from breaking down tyramine and this can result in dangerously high blood pressure.
- Vitamin B12 is usually found only in animal-derived products so the best way for vegetarians or vegans to obtain this nutrient is via B12-enriched nutritional yeast.
- Brewer’s yeast has been used to stimulate intestinal enzymes which can help relieve
- Nutritional yeast has a nutty and cheesy flavour while brewer’s yeast may taste bitter, like beer
- Sprinkle a spoonful of nutritional yeast over your porridge and skip the salt for a savoury and healthy twist.
