Facts about Probiotics

2018-08-21 17:12 Tuesday

Probiotics are known for promoting digestion, and are often prescribed by doctors for patients with diarrhea or constipation.

What are probiotics?

Probiotics refers to edible microbes that are conducive to the host. Probiotics have a wide range of health benefits, which include balancing intestinal flora, promoting protein and vitamin metabolism, preventing constipation, alleviating lactose intolerance, restoring liver injury, lowering the incidence of colon cancer, combating tumors, improving immunity, reducing cholesterol, and curing urinary system infections. Probiotics can be divided into three categories: Lactobacillus, bifidobacterium and gram-positive cocci.


Views on probiotics vary greatly from jurisdiction to jurisdiction.

Europe: The European Food Safety Authority has rejected health claim requests from manufacturers, citing a  lack of research proving the health benefits of probiotics

United States: The U.S. Federal Trade Commission prohibits spurious advertisements claiming that probiotics improve immunity and intestinal systems, alleviate constipation, or prevent colds.


China: The government has issued regulations covering the use of probiotics in food and additives, as well as introduced a list of edible probiotics for health foods.

Indonesia and Singapore already have mature regulations for products containing probiotics.

Food Standards Australia New Zealand (FSANZ) is in the process of revising laws related to probiotics products

Japan has strict rules over Foods for Specific Health Uses. All products with the Foods for Specific Health Uses (FOSHU) mark have undergone rigorous testing and approval process. No such product is allowed into the market until it has been the subject of epidemiological and clinical experiments.

Probiotics are classified as symbiotic bacteria

symbiotic bacteria

Intestinal flora can be divided into symbiotic bacteria, conditioned pathogens, and pathogenic bacterium. 99% of intestinal flora are symbiotic bacteria, including bifidobacterium, lactobacillus and bacteroides, which are beneficial for human health.

Due to the existence of symbiotic bacteria, conditioned pathogens including enterococcus and enterobacter, don’t pose any threat to human health. However, improper consumption of pathogenic bacterium can cause disease.

Alteration of intestinal flora can lead to IBS, IBD, enteritis, cirrhosis, NASH, atherosclerosis, and anxiety.

Probiotics are effective in the event that both of the following  preconditions are met: 1. They reach the specific position of their host. 2. A specific number of them survive and continue to live

Many probiotics products on the market, including lactobacillus beverages and yogurt, contain no or few active bacteria.


Streptococcus and lactobacillus bulgaricus in yogurt cannot survive in gastric acid. Thus, few probiotics can stay alive and reach the intestinal system after the inactivation of gastric acid. In other words, yogurt cannot replace medicine in balancing intestinal flora.

Dormant probiotics in capsules, pastille or powder packets are activated once they reach the intestinal system. Probiotics are advantageous for several reasons; they contain a large number of living bacteria, possess a long shelf life, and are easy to consume, thus making them a suitable option for individuals with intestinal issues.

When preparing milk powder containing probiotics, be sure to use warm boiled water  (35~40℃) .

Freeze drying is the optimal storage method for probiotics, which best prolongs their vitality.
