Did You Know?

  Did you know…

… the body has a various levels of pH (acid-alkaline), with no one “correct” reading for the entire body? A pH of 0 is completely acidic, 14 is completely alkaline and 7 is neutral. When the body is in good working order, human blood has a narrow pH window of about 7.35–7.45 (slightly alkaline). Saliva has a pH teetering around neutral at 6.5–7.4, healthy human skin has a slightly acidic pH of 5.5 and our digestive tract’s pH can range from a very acidic 1.5 to a neutral 7.0, depending on what stage of digestion is underway. The body needs a balance between the two and different parts of the body need different pHs. 

… the brain is 2-3% of our bodyweight, meaning a 150 pound human has a brain weighing about 3-4 pounds? The brain is 77-78% water, the tissue itself being about 50% fat and 40% protein. It houses the most cholesterol in our body- almost 25% of our total cholesterol is stored in the brain. 

… the human mouth has about 500-1000 different species of bacteria capable of living in it? About 150 different species and 20 million bacteria are living at one time in any given person’s oral cavity, although much of our oral microbiome diversity and number appears to be determined by ethnicity and hygiene. Each tooth has anywhere from 1,000 to 100,000 bacteria in a clean mouth ranging up to 100 million to 1 billion bacteria per tooth in an unclean mouth. Because much these mostly beneficial bacteria live in our saliva, we end up swallowing about 100 billion bacteria a day. 

… over the course of the day your entire bodily fluid content filters through the eye? It is thought this process exists to expose the body fluids (blood contents) to UV light which acts as a irradiation agent for pathogens and other abnormalities. For people who spend most of the time indoors and wear sunglasses whenever going outside we have to ask at what cost comes no UV exposure to the eye/brain and what other downstream effects that might have. 

Thanks for reading, have a great day!
