Bacteria are a group of single-celled organisms found everywhere on Earth, many of which cause injury, but some are helpful to the human body. Explore three types of good bacteria, how they benefit humans, and where to find them.
The article presents information on the benefits of probiotics, defined as bacteria which produce beneficial effects when ingested by humans. Organisms such as lactobacillus and bifidobacterium, often present in yogurt or kefir, are thought to offer some protection against a wide range of gastro-...
