EVERYDAY SCIENCE

Detailed explanation-1: -In fact, there are many more good bacteria than bad, according to the NHGRI . If you consume or come in contact with harmful bacteria, they may reproduce in your body and release toxins that can damage your body’s tissues and make you feel ill.

Detailed explanation-2: -Bacteria can be harmful, but some species of bacteria are needed to keep us healthy. The bacteria on our skin, in our airways, and in our digestive system are the first line of defense against foreign “invaders” (pathogens) that can cause infection and other problems.

Detailed explanation-3: -You constantly have both good and bad bacteria in your body. When you get an infection, there’s more bad bacteria, knocking your system out of balance. Good bacteria helps eliminate extra bad bacteria, returning the balance. Probiotic-supplements are a way to add good bacteria to your body.

Detailed explanation-4: -Most bacteria are good for us The bacteria in our bodies help degrade the food we eat, help make nutrients available to us and neutralize toxins, to name a few examples[7]; [8]. Also, they play an essential role in the defense against infections by protecting colonized surfaces from invading pathogens[8]; [9].

Detailed explanation-5: -As the name suggests, good bacteria in the body are bacteria that are known to have a positive impact on health. Bad bacteria can exist in human bodies at low levels without causing much harm. However, an imbalance between the good and bad bacteria may contribute to negative consequences.
