BACTERIA
Everybody when thinking about bacteria, think about them being bad. Germs and illness comes to mind.
But bacteria can also be good and help our bodies and immune system to function better.
So throughout this week I’ll post a few things under this subject because it’s important knowledge to have if you’re seeking better health.
Bacteria are organisms made up of just one cell (prokaryotic).
They are capable of multiplying by themselves, as they have the power to divide (Binary Fission).
Some bacteria (those known as aerobic forms) can function metabolically only in the presence of free or atmospheric oxygen; others (anaerobic bacteria) cannot grow in the presence of free oxygen but obtain oxygen from compounds. Facultative anaerobes can grow with or without free oxygen; obligate anaerobes are poisoned by oxygen.
Their shapes vary and these characteristics are used to separate them into groups.
Most bacteria are of one of three typical shapesrod-shaped (bacillus), round (coccus, e.g., streptococcus), and spiral (spirillum).
Bacteria exist everywhere, inside and on our bodies.
There are typically 40 million bacterial cell in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5×10 to the 30th power) bacteria on Earth, forming a biomass that exceeds that of all plants and animals. (Wikipedia)
Humans have 10 – 100 trillion cells in their bodies.
There are approximately 20 bacteria cells for 1 human cell in the body.
That means 200 – 2000 trillion bacteria in human bodies!
Bacteria makes up 10% of our DRY mass. An adult`s body weight is about 60% of water. So if you are 150lbs your DRY mass is 60lbs. Since bacteria makes up about 10% of our DRY mass. The average 150lb adult has about 6 pounds of bacteria. (WHAAAT?)
Most of them are completely harmless (rendered so by the protective effects of the immune system) and some of them are very useful (beneficial).
Bad Bacteria: some bacteria can cause infectious diseases, like cholera, syphilis, anthrax, leprosy, tuberculosis, lyme disease either because they end up in the wrong place in the body or simply because they are ‘designed’ to invade us.
Good Bacteria: When you eat, enzymes from your intestines, stomach, liver and pancreas break down carbohydrates into their building blocks called sugars; proteins into amino acids; and fats into glycerol, fatty acids and monoglycerides that can be absorbed into your bloodstream. However, many plant foods contain undigestible starches that cannot be broken down into sugars, so they cannot be absorbed in the upper intestinal tract. When they reach the colon, bacteria ferment these undigestible starches to form other chemicals including short chain fatty acids that protect your intestinal lining. from irritation and cancer, and are absorbed into your bloodstream to lower cholesterol and prevent heart attacks.

uuugggg. Bad flashback memories of Microbiology 201…
…although we had multiple bomb threats prior to both 201 and 202 finals, so that was a funny memory

At first glance (on the small iPhone screen) I thought that pic was like a tiramisu with pretzels and candy on top…
Hahaha
Now I’m hungry again…;)
