Виждам, че от поста ми не става много ясно какво точно имах напредвид, т.е. толкова криво го написах, че нямаше как да се разбере..
Не става дума за енергията, от която мозъка се нуждае 'в момента' за да функционира, а за ресурсите, нужни за изграждане, еволюиране и развитие.
След толкова изчетен материал на тази тема и толкова противоречиви мнения, това на мен ми звучи най-логично, не карам никой да вярва на въпросните учени или "учени", стигнали до тези изводи. А като цяло не съм против веган-ството, просто не мога да разбера мотивите.. поне логичните такива, не мога да приема че яденето на растения ще ви направи супер възвишени, ще живеете 800 години повече и ще сте 14 пъти по-здрави.
А има дори растения, съвсем безскрупулно похапващи месце..
Ето и малко научен материал:
Hibbeln (1998) pointed out that Palaeolithic nutrition was probably low in saturated fats and high in polyunsaturated fats (
the reverse is true today). Therefore, our ancestors consumed more omega-3 fatty acids (arachidonic acid, docosahexaenoic acid) and these are the major determinants of synaptic membrane fluidity. Hibbeln proposed that the move from being vegetarian and scavenging for meat to eating fish (rich in these fatty acids) promoted the sudden burst in intellectual/technological/cultural achievement about 35,000 years ago. Prior to that our ancestors (who had larger brains) had achieved relatively little.
Horrobin (1998) proposed that during the course of human evolution specific biochemical alterations led to changes in metabolism which enabled the human brain to expand in size and function more efficiently. He points out that a large brain per se does not automatically lead to creativity or intelligence as our ancestors did possess large brains, but for many millions of years showed no evidence of using them. Around 35-50,000 years ago there was a sudden burst of intellectual and creative achievement leading to religion, war, art, transport, complex culture and an agricultural revolution. If brain size was not the principal factor, then Horrobin argues that connectivity was the key.
Neural connectivity is determined largely by the availability of phospholipids, which make up 60% of the brain, and in particular the connections between neurons are made by phospholipid-rich axons and dendrites. These rely on a supply of the essential fatty acids (arachidonic acid, and docosahexaenoic acid) and the essential amino acids, which are vital for cell-function and neuronal signalling and can only be obtained from a diet rich in animal protein (meat, fish, eggs).
Horrobin points out that the sudden rise in creativity paralleled dietary changes as hominids moved from eating vegetation and fruit, to eating meat and fish. While these changes led to improvements in brain function.
