Lactic Acid Fermentation
and Ethanol Fermentation

Lactic acid fermentation is one of the three most popular ferments and the ferment responsible for creating a popular drink called Kombucha is called acetic acid vinegar fermentation.

Ethanol fermentation is what creates our alcoholic beverages. My favorite is red wine which is created by yeast and red grapes.

Lactic acid fermentation is responsible for the creation of a sour dairy food called yogurt which most Americans just love.

There are many different types of vinegars that are created by the acetic acid or acetic acid vinegar fermentation process. One of the most popular is apple cider vinegar.

Lactic Acid Fermentation

The presence of lactic acid,
produced during the lactic acid
fermentation process is responsible
for the sour taste and for the
improved microbiological stability and
safety of the food.

Popular Examples:

• Cheese
• Yogurt
• Sourdough Bread
• Sauerkraut
• Kimchi
• Kefir
• Lambic

Lactic Acid Fermentation and Your Body

1. When we perform strenuous exercises like running, we begin to breathe faster..to get more oxygen to our muscles.
2. When exercise requires more energy production than our bodies can deliver, the working muscles generate energy anaerobically (without oxygen).
3. Lactic Acid is created to allow energy to be produced for the muscles.

4. Lactic Acid is also created as a waste-product from the eating & metabolizing of food.

Too Much Lactic Acid Causes Problems

• The accumulation of excessive lactic acid in muscles may cause muscle cramps.
• Excessive lactic acid in the bloodstream may cause a form of acidosis known as lactic acidosis.
• Excessive accumulation of lactic acid may cause anxiety.
• Lactic acid is an underlying cause of tooth decay.
• If you consume foods high in calories from animal meats and fats, don't exercise enough, and have a highly stressful life. You are likely to have a huge accumulation of lactic acid in your blood stream.

Acetic Acid or Acetic Acid Vinegar Fermentation

Acetic acid is produced by fermenting various substrates
such as starchy solutions, sugar solutions,
or alcoholic foodstuffs...such as Wine or Cider with Acetobacter bacteria.
Acetic Acid gives vinegar its sour taste and pungent smell.

Popular Examples:

Apple Cider Vinegar

Wine Vinegar

Kombucha

Other Vinegars

Acetic Acid Fermentation
and Your Body

1. The primary reason we eat is to provide fuel for our body....or it should be!
2. Digestion breaks foods down into smaller units like amino acids, fatty acids, and glucose.
3. These nutrients need to be further metabolized before they can be turned into ATP...the only energy our cells can use.
4. The Krebs Cycle is used to produce ATP.
5. Before nutrients can center the Krebs Cycle, Acetic acid is used as a catalyst to form Acetyl Coenzyme A.
6. Acetyl Coenzyme A is an essential component used in the Krebs Cycle for the production of ATP.

Other Facts About Acetic Acid

• Acetic acid is a short-chained volatile saturated fatty acid.
• All other saturated fatty acids can be metabolized within the body to...Acetic acid due to it being the simplest fatty acid.
• Acetic acid can be produced in your large intestines by the bacteria....Bifidobacteria dining on carbohydrates.
• Your body can also produce Acetic acid from Alcohol that you consume.
• Acetic acid will build up in the body with the over-consumption of carbohydrates and not enough exercise.

Alcohol or Ethanol Fermentation

Alcohol is the by-product of certain yeasts dining on the sugars of various substrates...such as grapes, grains, corn, etc.

Alcohol Comes in Many Forms

• Beer
• Wine
• Liquor/Spirits

Beer usually has the lowest alcohol content followed by wine, and the highest alcohol content goes to ....Liquor/Spirits.

Ethanol Fermentation
and Your Body

1. Alcohol content and the amount consumed are important to remember when drinking, but they are not the only factors involved with the effects of alcohol.
2. A number of other factors influence how and to what extent alcohol affects the body, such as...a person's age, gender, and genetic background.
3. Alcohol is a Depressant - it slows your body down, making it difficult to think clearly.
4. Blurred vision, difficulty walking & slurred speech are some of the impairments detectable after only one or two drinks.

Alcohol Gets "VIP" Treatment in the Body

• It is absorbed and metabolized before most other nutrients.
• A sizeable amount of alcohol is absorbed directly across the walls of an empty stomach and can reach the brain within one minute.
• Liver cells normally prefer fatty acids as fuels.
• However, when alcohol is present the liver cells are forced to first metabolize the alcohol, letting fatty acids accumulate sometimes in huge amounts.
• Fatty livers are common for people who are heavy drinkers.
• Bottom Line - when your burning alcohol, you are not burning fat!
• "The Mystery of the Beer Belly" has finally been solved.
• In some cases of severe intestinal candida or yeast infection, people have measurable levels of alcohol in their blood.
