Probiotics, according to WebMD, are live bacteria and yeasts beneficial to health, especially the digestive system. Regarded as helpful bacteria that keep the gut healthy, they help move food through the gut. Found naturally in the body, probiotics are also found in certain foods like yogurt, kefir, miso, kimchi, sauerkraut and kombucha, as well as in supplements. The word “probiotic,” derived from Greek, means “for life.”
There are different types of probiotics. The lactobacillus may be the most common. It is found in yogurt and other fermented foods. It may help with diarrhea and digesting lactose, the sugar in milk. The bifido bacterium, found in some dairy products, may help ease the symptoms of irritable bowel syndrome (IBS). There are 30 species of bifido bacteria, which make up most of the healthy bacteria in the colon. They have been shown to help people with dental cavities, in addition to improving blood lipids and glucose tolerance.
For people with digestive problems, probiotics are a boon. They aid in nutrient absorption by helping the body to mine the vitamins, minerals, fats and amino acids from consumed foods. Researchers at the University of California-Los Angeles discovered a connection between healthy gut bacteria and the optimization and function of neurotransmitters, leading to a reduction in anxiety, depression and stress. They also may improve learning, sharpen focus and enhance memory, benefits of special interest to the middle-aged and elderly.
