Bacteria in our body get a bad rap.  Bacteria in our body exceed human cells 10 to 1 and many of them are also beneficial.  Bacteria produce vitamin K and B, and protect the human body against bad bacteria (Gunnars, 2018, para. 3).  Many people also have stomach issues, such as irritable bowel syndrome.  This paper will look closely at the basics of beneficial bacteria, types of bacteria, what good bacteria do, harms to it, and what foods have probiotics in them.  Can an app be made to remind people to eat foods with probiotics which help our bodies beneficial bacteria function? To understand beneficial bacteria (which are mostly in the gut) it is important to understand what good bacteria are and do for a human body.  There are about a trillion bacteria in our body and almost 99 percent of them are good (Leena, 2016, para. 1).  Probiotics absorb magnesium, create antibiotics, and fight bad bacteria or pathogens. Gut bacteria are usually located in the colon, small intestine, and other places where the outside environment can come intact with it (“Gut Microbiota Info,” 2018).  Gut bacteria also turn fibers into short chains which give the cells in the colon most of the energy that they need (Gunnars, 2018, para. 3).  If good bacteria and bad bacteria were imbalanced, then pathogens would grow quickly which causes diarrhea and the colon doesn’t absorb water, electrolytes, vitamins, and proteins as well (Marie, 2018, para. 3).  Gut bacteria are extremely important to the human body, so much that Dr. Gregor Reid, and professor at the University of Western Ontario, Canada says, “The bottom line is that we would be dead without them.”The human body has many different types of beneficial bacteria residing in it.  In fact, there are at least 1000 different types of bacteria that can weigh up to 2kg (“Gut Microbiota Info,” 2018).  Two-thirds of our gut bacteria our specific to our body which is like a human identity.  One bacteria Bifidobacterium Longum releases acids in the intestines that are poisonous to the pathogenic bacteria (Coscia, 2012, para. 4).  The bacteria Bacteroides Thetaiotaomicron helps humans (who can’t digest plant molecules with parts of the body) digest plant molecules (Coscia, 2012, para. 5).  Lactobacillus and Bifidobacterium are the most common bacteria that inhabits the human body and is also in many foods, such as yogurt and dairy products (National Center for Complementary and Integrative Health NIH, 2011, para. 19).  There are many different types of bacteria in the human gut that do different functions, like helping digest or fight pathogenic bacteria. Bacteria in our bodies perform many functions to protect our bodies by fighting the bad bacteria, burning carbs and digesting the food that we eat.  When the gut is healthy, bacteria make a protective barrier that fights bad bacteria and doesn’t allow them to seep through holes in the intestines (NIH, 2011, para. 9).  When there is dysbiosis(bacteria imbalance) the bacteria attach immune cells that kill the bad bacteria before the pathogens can attach to the body and wreck havoc (Mansfield, 2017, para. 3).  The bacteria E. coli make vitamin K chemically to prevent blood clots in the human blood flow.  E. coli are not dangerous unless it is mixed with food or water (Coscia, 2012, para. 7).  Beneficial bacteria perform many tasks, some even vital for humans to live by killing bad bacteria and protecting the body.  Even though beneficial bacteria are helpful, they also have weaknesses in which they can be vulnerable.  By not eating a diverse amount of whole foods bacteria diversity can be affected and there is a correlation to low gut flora to obesity (Coyle, 2018, para. 3).  Studies have also shown that alcohol has bad effects on beneficial bacteria.  One study had 41 alcoholics and 10 healthy people tested on their bacterial balance and 27% of the alcoholics had dysbiosis while the 10 healthy people didn’t (Coyle, 2018, para. 5).  Antibiotics are also don’t go very well with probiotics because even though they wipe out the bad bacteria, they also wipe out the good bacteria too.  Even though the good bacteria may come back in 1-4 weeks, they won’t come back as before (Coyle, 2018, para. 6).  Gut bacteria may be very important to the human body, but they must be treated well and able to thrive. To give helpful bacteria a boost, many foods have probiotics in them which are good bacteria and help them and favor beneficial bacteria growth over pathogens.  In 2014 Japanese researchers have found the the probiotics in peas Leuconostoc mesenteroides help benefit the immune system and are the front lines of fighting pathogens (Tarantino, 2016, para. 7).  Dark chocolate also provides prebiotics (which fuel probiotics) and probiotics; however American Chemical Society (ACS) only recommend 2-3 tablespoons of 70 percent or higher amount of cacao powder (Tarantino, 2016, para. 5).  Yogurt is made by adding two different types of bacteria into milk and a good source of protein; however, many bacteria die before they reach the intestines (Tarantino, 2016, para. 6).  By having probiotics in a diet can benefit the body by clearing up the toxins in the human body and possibly help rebound the body after a bacterial imbalance. Beneficial bacteria are very important the the function of the body.  By removing toxins by blocking them off with barriers or making nutritions for the body to give it a boost beneficial bacteria are essential to the survival of mankind.  There are many silent enemies that are still not realized like antibiotics that can give bad bacteria to colonize and create chaos.  While beneficial bacteria can run on their own, it can be given a boost if a diet rich in probiotics can help increase the numbers of beneficial bacteria or fighting back against the pathogens.  This research will be used for creating an app that can remind people to eat probiotics because they are good for the gut bacteria.
