The word “bacteria” has grown to bear a very negative connotation, implying that all types of bacteria have an inevitably detrimental effect on people’s health and well-being. However, the described assumption is quite far from the truth, with a significant number of bacteria being not only useful but also essential to the functioning of the human body and the sustenance of life. Since a vast range of bacteria that inhabit the human body facilitates its metabolism and function as protection against numerous threats, not all bacteria can be defined as bad.
Among the bacteria that have a positive impact on people’s bodies, one should mention the ones that are an inseparable part of the digestive system. These types of bacteria contribute to the metabolism not only by enhancing the digestion process but also by absorbing nutrients and encouraging the production of vitamins such as B6 and B12 (LeBlanc et al. 79.). Some bacteria play the role of protectors in the human body, preventing the development of diseases (“Chapter 4 – Cell Structure”).
Therefore, bacteria are not necessarily hostile elements to the human organism. Quite the contrary, without certain types of bacteria, sustaining life in people would be impossible due to the disruptions in the functioning of several bodily systems. Differentiating between the bacteria that pose a threat to public health and those that are crucial for sustaining metabolism and other processes in the human body is an important step in basic health education.
Due to the positive effects that bacteria inhabiting the human body have on its internal processes, it would be wrong to define all bacteria as bad. A great number of bacteria that contribute to food digestion and the absorption of nutrients produce an impressively positive impact on the functioning of people’s organisms. Therefore, it is important to differentiate between the bacteria that have a directly negative effect on people’s well-being and those that are indispensable to the proper functioning of people’s body systems, such as the digestive one.
