Probiotics are dietary supplements which contain beneficial bacteria. The most commonly used is lactic acid bacteria. Since they are capable of transform sugar (including lactose) and carbohydrate to lactic acid, they have long been used in food industry. The most common probiotic bacteria belong to the strain of Lactobacillus and Bifidobacterium. Probiotic bacterial cultures help restore gut flora. Since 70% of the immune system can be found in the intestines, the restoration of gut flora is essential for the immune system in order to be able to work properly.
Lactobacillus acidophilus is a species of gram positive bacteria in the genus Lactobacillus. L. acidophilus is a homofermentative, microaerophilic species, fermenting sugars into lactic acid, and grows readily at rather low pH values (below pH 5.0) and has an optimum growth temperature of around 37 °C (99 °F). L.acidophilus occurs naturally in the human and animal gastrointestinal tract and mouth. Some strains of L. acidophilus may be considered to have probiotic characteristics. These strains are commercially used in many dairy products, sometimes together with Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus in the production of acidophilus-type yogurt. Some strains of L. acidophilus have been studied extensively for health effects. The Mayo Clinic publishes a list of disorders for which L. acidophilus has been tested, grading the evidence for each use from strong evidence of effectiveness, through unclear, down to strong evidence of ineffectiveness. According to the list there is good (rather than strong) evidence supporting the use of L. acidophilus or yogurt enriched with it for the treatment of some vaginal infections; effectiveness for other conditions ranges from unclear to fair negative evidence. Some Lacidophilus strains may be able to survive gastrointenstinal transit, being resistant to bile, low pH, and digestive enzymes. They may then be able to adhere to human epithelial cell lines and human intestinal mucus. A blend of bacterial strains including L. acidophilus NCFM decreased the incidence of pediatric diarrhea. L. acidophilus led to a significant decrease in levels of toxic amines in the blood of dialysis patients with small bowel bacterial overgrowth. At adequate daily feeding levels, L. acidophilus may facilitate lactose digestion in lactose-intolerant subjects. Antibiotics taken orally will kill beneficial, as well as harmful, bacteria, including L. acidophilus. After a therapy that includes antibiotics, patients are occasionally instructed to take an L. acidophilus treatment in order to recolonize the gastrointestinal tract. To that effect, L. acidophilus is often sold in health stores in pill or powder form as a nutritional supplement, as well as being available in many yogurts. A part of the claims in favor of such treatment refer to attaining a better digestion thanks to a recovered normal intestinal floral. There are many fermented dairy products that use L. acidophilus including yogurt and some types of cheese. Sweet acidophilus milk is consumed by individuals who suffer from lactose intolerance or maldigestion, which occurs when enzymes (lactase) cannot break down lactose (milk sugar) in the intestine. Failure to digest lactose results in discomfort, cramps and diarrhea. Some bacteria have been shown to improve lactose digestion by providing β-galactosidase, while some L. acidophilus strains have been linked to improvement in symptoms and indicators of lactose indigestion.
In our everyday life, we are surrounded by more and more harmful things such as smog, chemicals, food additives, genetically modified foods, heavy metal, rubbish etc. Fortunately, there are several natural products which can help eliminate the harmful substances piled up in the body
Milk Thistle (Silybum marianum)
Milk thistle is a plant of the Asteraceae family. For centuries, it has been known as the most effective herb in terms of cleansing the liver. It protects and cleanses the liver, which is a medically proven and accepted fact. Its active substance is silibinin. Silibinin is an extremely efficient antioxidant; its antioxidant content is the multiple of E and C vitamins’. It enhances protein synthesis in the cells and supports the restoration of liver function via cleansing the liver. Studies reported that silibinin acts as a free radical trapper. Furthermore, silibinin helps the fission of liver cells and it also stabilizes the plasma membrane of liver cells. Milk thistle can be used for treating digestive problems and curing gallbladder problems.
