t is well known that a high salt diet leads to high blood pressure, a risk factor for an array of health problems, including heart disease and stroke. But over the last decade, studies across human populations have reported the association between salt intake and stroke irrespective of high blood pressure and risk of heart disease, suggesting a missing link between salt intake and brain health.
Interestingly, there is a growing body of work showing that there is communication between the gut and brain, now commonly dubbed the gut–brain axis. The disruption of the gut–brain axis contributes to a diverse range of diseases, including Parkinson’s disease and irritable bowel syndrome. Consequently, the developing field of gut–brain axis research is rapidly growing and evolving. Five years ago, a couple of studies showed that high salt intake leads to profound immune changes in the gut, resulting in increased vulnerability of the brain to autoimmunity—when the immune system attacks its own healthy cells and tissues by mistake, suggesting that perhaps the gut can communicate with the brain via immune signaling.
Now, new research shows another connection: immune signals sent from the gut can compromise the brain’s blood vessels, leading to deteriorated brain heath and cognitive impairment. Surprisingly, the research unveils a previously undescribed gut–brain connection mediated by the immune system and indicates that excessive salt might negatively impact brain health in humans through impairing the brain’s blood vessels regardless of its effect on blood pressure. |

Most of our brain cells are glial cells, once thought to be mere support cells, but now understood as having a critical role in brain function. Glial cells in the human brain are markedly different from glial cells in other brains, suggesting that they may be important in the evolution of brain function. |

Before the stroke, I was on a very spiritual plane. I ignored my body, took it for granted. When I look at my life, I see that I wanted to be free of the physical plane, the psychological plane, and when I got free of those, I didn't want to go anywhere near them. But the stroke reminded me that I had a body and a brain, that I had to honor them. |

I tried the paleo diet, which is the caveman diet - lots of meat. And I tried the calorie restriction diet: The idea is that if you eat very, very little - if you're on the verge of starvation, you will live a very long time, whether or not you want to, of course. |

Trust your gut instinct over spreadsheets. There are too many variables in the real world that you simply can't put into a spreadsheet. Spreadsheets spit out results from your inexact assumptions and give you a false sense of security. In most cases, your heart and gut are still your best guide. |

I believe we can prevent or delay most disease until the 9th or 10th decade. The goal is to prevent anything that can affect your quality of life prior to those years! By the time many of us get to the 9th or 10th decade, who knows where the new medical and science will take us? I am an optimist! |

Microplastics Found In 90 Percent of Table Salt (nationalgeographic.com)
New research shows microplastics in 90 percent of the table salt brands sampled worldwide. Of 39 salt brands tested, 36 had microplastics in them, according to a new analysis by researchers in South Korea and Greenpeace East Asia. Salt samples from 21 countries in Europe, North and South America, Africa, and Asia were analyzed. The three brands that did not contain microplastics are from Taiwan (refined sea salt), China (refined rock salt), and France (unrefined sea salt produced by solar evaporation). The study was published this month in the journal Environmental Science & Technology.

Salt Makes You Hungry, Not Thirsty, Study Says
Salty diet makes you hungry, not thirsty. Science Daily reports: "In a study carried out during a simulated mission to Mars, an international group of scientists has found exactly the opposite to be true. 'Cosmonauts' who ate more salt retained more water, weren't as thirsty, and needed more energy." So if you don't want to gain weight on your trip to Mars, don't eat salty chips. If you don't want to gain weight at home, maybe you should stay away from them as well.
From the report: "The studies were carried out by Natalia Rakova (MD, PhD) of the Charite and MDC and her colleagues. The subjects were two groups of 10 male volunteers sealed int...

Alcohol Can Cause Irreversible Genetic Damage To Stem Cells, Says Study (theguardian.com)
A new study, published on Wednesday, states that drinking alcohol produces a harmful chemical in the body which can lead to permanent genetic damage in the DNA of stem cells, increasing the risk of cancer developing. From a report:
The research, using genetically modified mice, provides the most compelling evidence to date that alcohol causes cancer by scrambling the DNA in cells, eventually leading to deadly mutations. During the past decade, there has been mounting evidence of the link between drinking and the risk of certain cancers. "How exactly alcohol causes damage to us is controversial," said ...

Scientists Discover a Game-Changing Way To Remove Salt From Water
[T]he ability to quickly and easily desalinate water has long been a goal of scientists around the world. And now, a group of researchers from Columbia University believe they've found a way to do it. The process is called Temperature Swing Solvent Extraction (TSSE) and it's designed to purify hypersaline brines (water that contains a high concentration of salts, making it up to seven times as salty as seawater). This kind of waste water is produced by industrial processes and during oil and gas production and it poses a major pollution risk to groundwater.

A New Mexico woman is being tested for the Ebola virus in Albuquerque after recently returning from Africa, according to state health officials.
And in Sacramento, Calif. hospital officials say a patient ?who may have been exposed to the Ebola virus? is also in isolation as blood samples are tested to rule out the virus.
The 30-year-old woman is in isolation as a precaution at the University of New Mexico Hospital after experiencing symptoms similar to the virus that has killed more than 1,200 people overseas as of Tuesday, according to health officials.

Astronaut Scott Kelly Describes One Year In Space -- And Its After Effects (brisbanetimes.com.au)
53-year-old astronaut Scott Kelly shared a dramatic excerpt from his new book Endurance: A Year in Space, A Lifetime of Discovery in the Brisbane Times, describing his first 48 hours back on earth and what he'd learned on the mission:
I push back from the table and struggle to stand up, feeling like a very old man getting out of a recliner... I make it to my bedroom without incident and close the door behind me. Every part of my body hurts. All my joints and all of my muscles are protesting the crushing pressure of gravity. I'm also nauseated, though I haven't thrown up... When I'm finally ver...

In the 1990s, a British scientist, Jennifer Luke, discovered that fluoride accumulates to strikingly high levels in the pineal gland. (Luke 2001). The pineal gland is located between the two hemispheres of the brain and is responsible for the synthesis and secretion of the hormone melatonin. Melatonin maintains the body?s circadian rhythm (sleep-wake cycle), regulates the onset of puberty in females, and helps protect the body from cell damage caused by free radicals.
While it is not yet known if fluoride accumulation affects pineal gland function, preliminary animal experiments found that fluoride reduced melatonin levels and shortened the time to puberty. (Luke, 1997). Based on this and other evidence, the National Research Council has stated that ?fluoride is likely to cause decreased...

Call it over stimulated chakras, call it being too cerebral, call it introversion, introspection, anxiety, depression, obsessive compulsion, insomnia, dehydration, high blood pressure, call it preoccupation, call it loneliness, call it unsynchronized vibrations or stress. The truth is you think that you can think your way through life and out of this mindset, and continually finding out that you can't. It's not yoga or mediation, it's not pills or constructive hobbies, exercise or organization. You need to let go.

80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on TV. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue.
