The yeast is a microscopic fungus, Latin name Saccharomyces cerevisiae , and whose biochemical function is to ferment the sugars of barley.The fermentation is a chemical reaction that involves the degradation of sugars complexes grains into simpler molecules, alcohol . Generally, the resulting alcohol is ethyl alcohol or ethanol .

Brewer’s yeast acts in this way on barley grains for brewing.

What is the use brewer’s yeast?

The Saccharomyces cerevisiae is a microorganism that produces several beneficial substances to the human body during the fermentation process and chemical species for its own operation. Elements such as selenium, chromium, trace elements and various vitamins, especially the B complex, are produced in this process.

  • The selenium is a very effective antioxidant element and supports the health of the cardiovascular system.
  • The chromium is an element that influences the transport of glucose into the cell interior, which facilitates work action of insulin produced by the pancreas, promoting tissue sensitivity of the organism to the latter.

In general, brewer’s yeast is used to:

  • Lower cholesterol
  • Regulate blood pressure
  • Benefit cardiac activity
  • Help lower blood glucose levels
  • Collaborate in liver processes
  • Be used as a topical disinfectant
  • Help the digestive system
  • Help brain mechanisms
  • Improve skin, hair and nail health
  • It is anticancer
  • It is antitoxic

Lower cholesterol

Among the substances in beer yeast are lecithin and choline , which enhance the production of good cholesterol (HDL: High Density Lipoprotein) and stimulate the liver by increasing bile production , thus eliminating bad cholesterol ( LDL: Low Density Lipoprotein).

Regulate blood pressure

Due to its high contribution of sodium and potassium in fermentation, brewer’s yeast has a diuretic effect, which ultimately helps to reduce blood pressure.

Benefit cardiac activity

Thanks to the fact that brewer’s yeast provides several substances and elements, it helps the proper functioning of the heart muscle, improving its performance. It favors adequate systole (compression) and diastole (expansion) so that the blood flows at a good rate through the body.

Reduction of glucose levels in the blood

Brewer’s yeast helps by activating insulin, making it more “effective”, thanks to chromium, zinc and selenium that intervene in the process of assimilation of sugars.

Collaborate in liver processes

Brewer’s yeast stimulates the liver, contributing to the detoxification functions that this organ performs.

Yeast delivers substances that are involved in detoxification processes. Selenium, choline, methionine and the B complex vitamins, among them.

Can be used as a topical disinfectant

The Saccharomyces cerevisiae has healing qualities and topical disinfectants, so it is commonly used for:

  • Treatment of skin conditions such as acne, and for centuries in various local treatments to treat wounds, eczema, psoriasis and various skin infections caused by various germs, knowing its healing virtues since the time of the Egyptian pharaohs (Eber papyrus) .
  • In times of the Greeks, Romans and during the Middle Ages, it was used to treat various diseases , being effective in several cases, but as usual in humans, on many occasions it was attributed virtues that it did not have.

Saccaromyces cerevisiae yeast ferments the sugars in barley to produce beer alcohol

Help the digestive system

The Saccharomyces cerevisiae helps normalize the intestinal flora , reducing toxins that exist in the digestive tract, because of the excess of microorganisms belonging to the intestinal flora and consequent waste produced by the metabolic reactions.

Help brain mechanisms

Improvements have been seen in patients with Alzheimer’s and other mental illnesses. Consuming brewer’s yeast supports the functioning of the nervous system, thanks to its choline content, which acts as a neurotransmitter.

Choline is a substance that is usually grouped with the B complex vitamins. Its formula is (CH 3 ) 3 N + -CH 2 CH 2 OH] X  .

Improve skin, hair and nail health

Brewer’s yeast has many beneficial properties for the body.

Brewer’s yeast, thanks to the substances it provides, promotes favorable effects in the body:

  • The growth and development of the cells that make up the skin
  • The production of keratin to strengthen the nails.
  • It contributes with nutrients such as glutathione , B vitamins, biotin, minerals and various trace elements, of which nails, skin and hair are made.
  • The regeneration of the skin is faster.

In addition to its topical and disinfectant properties, it is highly recommended for dermatology and acne treatments.

It is an anticancer

Studies indicate that Saccaromyces cerevisiae has anticancer properties. This is the case of sulfur, an element that composes it, whose action against cell degeneration has been analyzed.

It is antitoxic

Brewer’s yeast is considered an anti-toxin; In addition to its work for the liver and kidneys, it should be noted that “cellular liquid” brewer’s yeast has substances such as cysteine, which intervenes in the elimination of heavy metals such as cadmium and lead.

It is also used to treat some side effects produced after cancer treatment by radiotherapy.
