Seed oil seems to lower thyroid activity and that could possibly slow down reflexes.
In the Victorian era, average reflexes were around 0.15 to 0.17 seconds. Today, average reflexes have slowed down to 0.25 seconds.
This change in reflex speed parallels the strange increase in degenerative conditions that has occurred over the same time period, and the other phenomena that suggest a rise in thyroid troubles across the population. For example, average body temperature has also gotten slightly colder since that time.
The major dietary change since the Victorian period has been an increase in seed oil consumption, and an increase in strange chemicals in the food like pesticides and additives. Are these things slowing down our reflexes?
