  • For decades, researchers have tried in vain to answer the question: What causes schizophrenia?
  • At the same time, we've developed a growing understanding of how intimately linked the bacteria in our gut and our brains are.
  • New research shows that schizophrenics have vastly different microbiomes, potentially uncovering a cause of — and maybe a future cure to — schizophrenia.

How antibiotics used in factory farming destroy our microbiomes

Good bacteria are our friends. We need to protect them.

  • More and more research nowadays links good gut flora to several health benefits, such as the inhibition of Alzheimer's to a fast metabolism.
  • Since we're over prescribed antibiotics, and because much of the meat we consume comes from animals that were fed antibiotics, we are destroying much of the good bacteria, and often at the risk — because of our diets — of replenishing them.
  • A well-rounded diet that's light in animal protein, high in macronutrients, and supplemented with a good intake of prebiotics can ensure we're keeping probiotics flourishing.

The cause of Alzheimer’s may be gum disease

This means the disease may be curable and a vaccine possible.

  • Bacteria in periodontitis seems to be the culprit.
  • Reported amyloid and tau buildups may be a response, not a cause.
  • Compelling research offers a genuine reason for optimism.

  • Scientists found a rich ecosystem deep inside the planet.
  • The "deep biosphere" contains mostly bacteria and microbes.
  • The amount of life below the surface is hundreds of times greater than the combined weight of all the humans.
