Shouji KONDO's "Japan’s Longevity Villages and Short-lived Villages"

Introduction

Shouji KONDO(1893-1977), is a Japanese epidemiologist who claimed he did the on-site observation research at over 1000 villages in Japan in 1930-1970s. In his book "Japan's Longevity and short-lived villages", he presented some very interesting insights regarding longevity based on his careful observations.

Insights

  1. Eating habits is the most contributing factor to longevity.
  2. Depending on refined rice for large portion of calories intake shortens the life expectancy.
  3. Consuming salt-based preserved foods with refined rice shorten the life expectancy.
  4. Eating vegetables and sea weeds is good for the l.e.
  5. Eating fruits like oranges doesn't replace vegetables.
  6. Doing physical labor is not bad.
  7. Eating soy-based product regularly is good.
  8. Eating a lot of fish or meat meals causes the heart failure, shortens the life expectancy.
  9. Eating small fish whole body enhance the health.

Comments

  • Eating vegetable and less eating refine rice is mutually associated. The excretion of digestives and the absorption of nutrients is quicker and intense if the nutrients is dense, condensed and concentrated inside the digestive tube. Vegetables-contained fibers mitigate the condense of nutrients as well as provide vitamins.
  • Sea weeds is the good mineral supplementation as well as fiber.
  • Eating soy product seems to be associated with the supplement of proteins.
  • Item 8, the cause of the heart failure is mysterious. 
  • Consuming huge amounts of salt is known to cause cardiovascular diseases, particularly in the brain.
  • He recommended small fish rather than pieces od big fish. It seems important eating whole fish body including bones which is consisted of minerals.

How does Magnesium work in muscles and nerves

イメージ
This is a short introduction of the importance of Magnesium in human bodies. Only 3 sections to read. If you need further informations, please feel ease to contact us from  here . Since Magnesium is water soluble and the human kidney has the high tendency to wash out Magnesium from human body via urine(i.m.o., the sympathetic nerve stimulant causing Magnesium loss from urine is a major cause of Magnesium depletion in our modern society, the blog entry here ), it is recommended that human beings with wholesome kidneys frequently supplement Magnesium in some form, which has been my recommendation since no later than 2021/12/10. It is the story-tellling explanation why human kidney is so Magnesium-resilient is they are still relying on "fish kidney" which allows them to filtrate sea water at all time.  Biological Function of Ca 2+  and Mg 2+ Ca 2+   influx is the functional trigger of muscle and nerve cells (According to, e.g. Medical Biochemistry By Baynes & D...

Magnesium on brain protections

 0. Introduction There are several evidence that Magnesium has brain-protection function.  1. Micro insights on nerve cells 1.1 Model study suggests not a simple role of Magnesium In-vitro model suggests that the Magnesium-removed, voltage-controlled state leads to the epilepsy-like phenomenon, and it is NMDA receptor dependent, according to famous ” Principles of Neural Science, Eric R. Kandel, fifth edition, Japanese translation(2014).". It means that Magnesium is for not only conforming the voltage but also having the excitation suppression effects.  Google Gemini conversation here . Note: no Magnesium, voltage-controlled is a very unlikely situation in living human bodies. This is a laboratory experiment on glass dishes. 1.2 The Alzheimer's neuronal  Ca 2+   accumulation hypothesis Some studies' evidence supports the hypothesis that the neuronal Ca 2+ accumulation causes Alzheimer's. It proceeds the onset of the dementia, even the accumulation of Aβ, w...

The Magnesium circulatory accumulation ashore hypothesis

0. Introduction This article proposes a hypothesis which reveals a long-standing question on why Japanese Edo-era people was so physically capable. Additionally, it may cast some lights to the cardiovascular diseases preventions or the epilepsy for the old. The key is the Magnesium accumulation inside organics, including human bodies. 1. Since 1600s' to 1930s' Japanese people supplied the fish meal fertilizer to grow crops 1.1 Overview In order to provide essential elements to crops, fish meal fertilizer is utilized on large scale. Vegetations except from crops are also provided into fields to provide organic elements. 1.2 Understanding the miracle recovery of the lost forest since 1700 in Japan―Contributions by Conrad Totman and, Google Gemini. Conrad Totman claimed in his book " The Green Archipelago: Forestry in Preindustrial Japan " (1989)  that Japan recovered the forest in 18th century that she lost through previous few centuries depending on organized labour ...
