Beneficial bacteria are harmless
bacteria which are useful in many
chemical processes, including digestion of food and duplicating DNA. Beneficial bacteria are also used to keep
plants and
animals healthy in
agriculture.
Yogurt,
sour cream, and some types of
cheeses are created in part using this type of bacteria.
Due to the overwhelming amount of antibiotics we use today, some people are encouraged to eat foods containing probiotics to aid in digesting food, synthesize vitamins, process hormones, and recover from illness.
