Will you be surprised to hear that the human race becoming more and more stupid? Despite our successes on over the past tens or even hundreds of years, some experts suggest that people lose cognitive ability and becoming more emotionally unstable. Geneticist from Stanford University Dr. Gerald Crabtree believes that the intellectual extinction of the human race is associated with adverse mutations. But people’s intelligence also suffers from other factors.
According to Crabtree, our cognitive and emotional abilities feed and are determined by the combined effort of thousands of genes. If in one or more of these genes will cause a mutation – which is quite probably it will have a negative effect on our intelligence and emotional stability.
“I bet that if the average inhabitant of Athens is 1000 years before AD suddenly appeared among us, then he or she would be among the most intelligent and intellectually living people of our time, with good memory, a wide range of ideas, and a clear idea of important subjects. Moreover, I assume that he or she would be some of the most emotionally stable personalities, ” so Crabtree begins his article in the scientific journal Trends in Genetics. ”
The geneticist further explains that people with specific adverse mutations are more likely to survive in the number of “strong”. Darwin’s theory of “survival of the most fit “less applicable in modern society, so those with the best genes will not necessarily dominate in society as it was in the past.
This theory has several strengths, but it raises key question: Are genes the main cause of common the cognitive decline of the human race? If people really experiencing this effect, it is extremely important for us to determine others possible reasons for it. Let’s take a look at what role in this plays our power system.
It’s sad, but it’s a fact: our food system has a contribution in a decline in human intelligence across the globe.
Drinking water, fluoride lowers IQ
Harvard University researchers found that the key compound for the water supply system – fluoride – lowers IQ level and leads to a dull population. Scientists have published their findings in Environmental Health Perspectives, to conclude that “the results obtained speak in favor of the fact that adverse effects of fluoride affect development brain of young children. ”
“In our study, we found a significant association “dose-response” between serum fluoride and IQ of children … This already the 24th study that discovers a similar correlation. ”
Pesticides lower human intelligence
One study published in the Proceedings of Almanac the National Academy of Sciences “found that pesticides, which are abundant in modern food products, create long-term changes in the general structure of the brain – and these changes associated with a decrease in intelligence and a decrease in cognitive functions. More specifically, scientists have found that specific pesticide chlorpyrifos leads to the appearance of “significant anomalies.” More importantly, a negative effect is detected even with very low doses of pesticide.
Processed Foods and High Fructose Corn Syrup make people stupid
Watching 14 thousand children, British researchers found a relationship between processed foods and lower IQ. Having analyzed the data on the diet of children and questionnaires filled out by them parents, scientists have found that if children consume processed products at the age of three, then over the next five years very probably the beginning of processes of decrease in the level of intelligence. With another hand, in children eating nutrient-rich foods such as fruits and vegetables, there is an increase in intelligence throughout three year period.
Interestingly, especially a close relationship with a decrease in intelligence installed in one specific ingredient of processed food, widespread throughout the globe – highly fructose corn syrup. Scientists have concluded that this syrup disrupts brain function, undermining learning abilities and remembering. In fact, official articles go so far that directly state that corn syrup makes people “stupid.”
It is possible that genetic mutations lead to a decrease human intelligence but let’s stop for a second and let’s think what we do with ourselves so that these reductions are even more significant.
