Lactobacillus Casei Shirota Yakult (Casey)
What Is Lactobacillus Casei?
The word “case” means a container or vessel. In other words, it refers to the bacteria’s container. The name “lactobacilli” comes from the Greek word meaning milk. When humans consume foods rich in milk products such as yogurt, cheese, and cream they are able to absorb beneficial nutrients from these foods. These nutrients include calcium, vitamin D, iron, folate, potassium and many others. The human body needs all of these vitamins and minerals in order to function properly.
There are two types of bacteria that live in our intestines: Bacteria and Proteins. Bacteria are essential to life because without them there would be no cells or organs. However, if the bacteria die off, then the body cannot function properly. For example, when a person eats food contaminated with harmful germs such as salmonella or E.
coli bacteria, their bodies become ill and may even kill them. The same thing happens when someone drinks alcohol containing poisonous chemicals like methanol or ethyl alcohol which cause intoxication and death due to liver damage. “Lactobacillus” and “Bifidobacterium” are both types of beneficial bacteria that live in the body.
Lactobacillus is the most common type of bacteria found in the small intestines. It is also found in other areas of the body such as the mouth, genitals, etc. without which life could not sustain itself. There are many types of Lactobacillus including L.
acidophilus, L. casei, L. reuteri, and others, that all have different effects on the body. The most common type of these is L. acidophilus because it has the most benefits to offer. The lactobacillus bacteria produces lactic acid which breaks down and destroys toxic substances in the body. It also produces enzymes and nutrients that keep the body healthy. For example, L. acidophilus helps in the synthesis of B-vitamins and helps with the digestion of food. The cell walls of these bacteria contain amino acids such as glycine and alanine. Lactobacillus also help in regulating cholesterol levels in the body by breaking it down into bile salts.
Bifidobacteria are another type of beneficial bacteria found in the intestines. These are slower growing bacteria than the lactobacilli. Bifidobacteria act as a protective barrier against harmful microorganisms entering the body. They produce an acid that kills any harmful bacteria attempting to enter the body through the intestines.
The most common types of beneficial bacteria are:
L. Acidophilus – This is probably the best known and most widely used probiotic. It is known as a colonizer because it colonizes or resides in the large intestine. It is used to treat diarrhea, constipation, vaginal yeast infections, and urinary tract infections.
L. Plantarum – This is a type of bacteria that can be found in the body naturally but not in large quantities. It is known as a saccharolytic bacteria because it breaks down sugars and carbohydrates into lactic acid. For this reason it works well with preventing flatulence and diarrhea.
It also treats ulcers, vaginal yeast infections, urinary tract infections, and respiratory problems such as sinusitis and bronchitis.
L. Salivarius – This is the main bacteria that resides in the mouth and is used to prevent tooth decay and periodontal disease. It prevents bad breath by breaking down proteins from food and producing volatile sulfur compounds (VSCs). When these VSCs come in contact with the bad breath producing bacteria in our mouths they destroy them.
L. Casei – This helps with digestion and can be used to prevent vomiting and nausea caused by chemotherapy. It also prevents diarrhea, constipation, stomach ulcers, and irritable bowel syndrome (IBS).
B. Bifictus – This is the most widespread bacteria found in the intestines and is known as a colonizer. It prevents E. coli from invading the body.
It also prevents diarrhea, intestinal infections, and respiratory problems.
B. Longum – This is a beneficial bacteria that promotes the synthesis of certain amino acids such as tryptophan which in turn produces the neurotransmitter serotonin. It also has been used to treat diarrhea, constipation, and urinary tract infections.
B. Breve – This is a type of bacteria that has been used to prevent and treat vaginal yeast infections.
