Brain - and the Centenarian Diet
University of Washington, "The adult human brain weighs about 3 pounds (1,300-1,400 g). The adult human brain is about 2% of the total body weight ... but, uses 20% of the body's energy, oxygen, and blood flow, - more when sleeping." ... interesting?
The Brain Evolution | Diet Ramifications
The Paleontologists have been busy, and the above chart follows brain size development by showing cranial capacity from fossil records. It is a timeline showing some of the temporal intersections of diet, natural selection and one of the many changes in human morphology, of which, brain crainal capacity would seem to be the most important. From a nutritional perspective, what is important is that the brain consumes roughly 16 times as much energy as muscle tissue per unit of weight. (1a, 5, 6)
The above chart allows us to draw some conclusions: 1) Cooking food started making a difference to brain size and physiology, 2) Eating cooked meats and seafood's also contributed to this change. Cooking food or a "Soft Diet" is surprisingly just being research, Professor Richard Wrangham, Harvard University, (Video) has a good discussion on current research and thinking. The Soft food diets allow for approximately 44-78% more available protein uptake (Note 2), and more available starches for energy. The amount of calories taken across the gut wall, fueled our bodies better and allowed for faster growth in organs that required more energy.
Its all about Energy, as current evidence shows that our brain size increased 350% and blood flow to the brain increased 600%, clearly indicating our brain's energy requirements. With our large brain using 20% of metabolic energy and more when sleeping (Circadian Rhythm and Time-Restriced Feeding, TRF) our metabolism needed to produce more energy for our complex bodily systems and complex thinking. (Note 1)
In addition, higher energy source allowed for smaller intestines, better immune system, more reproduction, more time for hunting and social contact, and bigger brains. The brain is extremely expensive in metabolic terms, and uses about 20% of food calories. Humans have the biggest brain and the smallest gut among primates. (7,8)
Anatomy of the Body's Energy: The brain, heart, liver, and kidneys consume about 60% of the body’s energy intake thereby dominating resting human energy metabolism. The heart and kidneys are metabolically more active than the brain but, being larger, the brain takes a higher proportion of the body’s total energy needs, i.e. about 20–23% of the body’s total energy requirement despite representing only 2.0–2.3% of adult body weight (9,9a,b). Three major parameters linked to brain energy metabolism – cerebral blood flow, oxygen consumption and glucose metabolism - can all be measured independently in humans using minimally invasive techniques. (9c,d)
The Soft Diet is reflected in the human teeth, in that about 1.9 million years ago, they became smaller and less sharp. We took on human characteristics, and not those of
meat eaters or leaf eaters. Our hip and waist bones got smaller giving the indication of smaller intestines. Humans became more efficient at using their calorie resources. (10,10a)
The brain is made almost entirely of fat (57%) and protein (38%), and contains very little carbohydrate (5%). Our modern brains grew up in a low glycemic index environment.
From the diagram and recent evidence, the last 200,000 years show a doubling of the brain size. The recent evidence comes from an area of the world where fish were introduced to out diet.

Attaching to the "Cloud" - the Brain Cloud Connection
This may all be a
Moot Point. According to Ray Kurtzweil,
we will become attached to the "Cloud" and the "Brain Cloud Connection" will be real.
We will see the emergence of Homo cloudus sapiens in 2029, and by 2045 Cloudus complexanus pluggedensis.
As chief architect at
Mootest Pointest - Cloudus complexanus pluggedensis, bodyless needs only electricity.
Ray Kurzweil - Exponential power use, in 1000 years will require the entire energy output of the Sun.
See ... with the invention of the cloud we will not need our body much longer ...
Fasting | the Normal State for Humans
Fasting is the Normal State for Humans: in the biological world, most organisms exist in a fasting state and Eating is a Stress State. (Note 3) During starvation periods and lack of carbohydrate sources (seasonal), the formation of ketone bodies increases dramatically. Prolonged low levels of insulin result in both increased fatty acid release from adipose tissue, and increased amounts of the enzymes required to synthesize and utilize ketone bodies. Ketone fuel is more efficient and has less waste by products. (11) Modern elite runners are now proving that Ketogenesis Energy provides 50-80 Kcal vs 2-3 Kcal of glucose energy. This makes the human animal an excellent long distance runner.
When you are asleep, you are fasting. Most animals alternate periods of feeding with periods of fasting often coinciding with sleep. Fasting and Time-Restricted Feeding, TRF, allows mammals to enter alternative metabolic phases, which rely less on glucose and more on ketone body sources. Both intermittent (IF) and periodic fasting result in benefits ranging from the prevention to the enhanced treatment of diseases.
The human organism has evolved DNA repair and DNA protection against oxidation and regeneration using the body's own stem cells. It has been shown that fasting and exercise builds new neurons in the CNS and the Brain. This regeneration response represents one of the most potent examples of comprehensive cellular reprogramming and appears to be functioning in virtually all organisms. (12,12a)
Hippocrates, like the
Chinese with their
Yin and Yang, believed in
Balance and Harmony. When the body is out of balance, this caused diseases.
Hippocrates believed that the body had 4 humors (body fluids): blood, phlegm, yellow bile, and black bile. When the humors were balanced, a person was healthy. The belief was that too much or too little of
any of the humors caused disease. An excess of black bile in various body sites was thought to cause cancer. This
Thinking is in line with
The Metabolic Model of Cancer - The New/Old Frontier.
The origin of the word cancer is credited to the Greek physician Hippocrates (460-370 BC), who is considered the “Father of Medicine.” Hippocrates used the terms carcinos and carcinoma to describe non-ulcer forming and ulcer-forming tumors. The Roman physician, Celsus (28-50 BC), later translated the Greek term into cancer, the Latin word for crab.
This theory of cancer was passed on by the Romans and was embraced by the influential doctor Galen’s medical teaching, which remained the unchallenged standard through the Middle Ages for over 1,300 years. During this period, the study of the body, including autopsies, was prohibited for religious reasons, which limited progress of medical knowledge.
The brain requires 20% of the body's energy production and a constant flow of nutrients. Cells have evolved a host of molecular pathways that can sense nutrient concentrations,
both intracellular and extracellular, and quickly regulate gene expression and protein modification to respond to any changes. The body need a non-stress, i.e. sleep/fasting, time to repair and regenerate.
No one has the all the answers yet, but we know that letting the body respond using its built in adaptations to
Living and Repair of metabolic damage is important. (13,13a)
Agriculture: Modern farming is a new development, about 10,000 years old, and has allow for the development of large scale societies and populations. Our big brain and intelligence have allowed for conquering our environment, and we have conquered bacterial disease and working on viruses. But, with refined foods new nutritional diseases have been introduced i.e. inflammation diseases, neurodegenerative diseases, obesity, diabetes and others within this century. For the first time, our life expectance is going down ... ? ... the Obesogenic Diet.

Ok - Now What?
Our modern society created a Nutritional Disease; therefore, we need a Nutritional Solution. Eating too many of the wrong carbohydrates too often is what causes blood sugar and insulin levels to rise, placing us at high risk for insulin resistance and Alzheimer’s Disease (Type 3 Diabetes). Our bodies have evolved to handle whole food sources of carbohydrates like peppers, broccoli, onions, and tubers etc., but our bodies simply aren’t equipped to cope with modern refined carbohydrates like refined flour and sugar. Ref: The Premise for this Nutritional Solution.
From Dr. Gary Fettke - Dr. Georgia Ede, a Harvard- trained psychologist says ... “Despite swimming in a sea of glucose, brain cells in people with insulin resistance literally begin starving to death.”
Alzheimer's is now being called Type 3 Diabetes by some doctors. According to
Dr. Georgia Ede - Diagnosis: Diet and Preventing Alzheimer's -,
points out that 80% of Alzheimer's patients have
Insulin Resistance - or full blown Type 2 diabetes. Preventing Alzheimer’s disease Is easier than
we think as researchers now understand that insulin resistance is a powerful force in the development of Alzheimer’s Disease.
Dr. Ede explains ...
It’s more accurate to think of it this way: Insulin resistance of the body is type 2 diabetes; insulin resistance of the brain is type 3 diabetes.
They are two separate diseases caused by the same underlying problem: Insulin Resistance.
Mounting research also suggests Alzheimer’s (Diabetes of the Brain - Type 3) disease is intricately connected to
Insulin Resistance; even mild elevation of blood sugar is
associated with an elevated risk for dementia (mean age baseline was 76 - higher average glucose levels within the preceding 5 years were related to an increased risk of dementia ). (30)
Diabetes and heart disease also elevate your risk, as all three conditions are rooted in Insulin Resistance.
Say NO to Sugar and get your
The brain is made almost entirely of fat (57%) and protein (38%), and contains very little carbohydrate (5%). Our modern brains grew up in a low glycemic index environment. For 2 million years of our evolution, we ate much less carbohydrate than we do now, and certainly no refined or processed carbohydrates. The brain needs blood sugar and insulin levels to be nice and even in order to keep brain chemistry stable. The Real Rub - we were never designed to use carbs as fuel. Also ref: ... Carb-Loading (debunked).
- Fat in general makes up approx. 80% of our brain and nervous system. Ref: ... this site Health Brain
- 50% of the body's fat is
Satruated Fat. 11% arachidonic acid and 25% of fatty acids making up the brain neurons and cells, are DHA - Omega-3. Fats and Oil - Where did the Omega-3s Go? | contributor april/2016. (31)
- Carb-loading Debunked - as it has proven false and many elite athletes are now becoming
Fat Adapted for best results. Just by pure math it can be shown why
Carb loadingis wrong, as we simply cannot store enough
- Ketones are an abundant, stable and steady source of fuel, even in the absence of regular eating. We can store 100Kcal of fat energy as opposed to 2Kcal of carbs. Dr. Hasselbalch showed that a ketogenic state results in a substantial (39%) increase in cerebral blood Flow. [ Hasselbatch SG, et al. 1996]. (32)
Importance/benefits of fat and ketone bodies (Ketosis) in the Brain.
Simple solution, avoid carbohydrates as they offer no known nutritional benefits. Carbohydrates are however packaged in food source organisms that do provide Longevity Vitamins, Our foods provide Phytonutrients, macronutrients, micronutrients (for critical DNA repair) (R1), Polyphenols, Phytosterols, Flavonoids, Lignans, Antioxidants, and Carotenoids, that do allow life to continue. Ref: 100 richest dietary sources of polyphenols. (Resource 1,2,3)
Certainly avoid processed carbohydrates, fats and oils, and packaged and processed foods. A direct result of too many carbohydrates is Insulin Resistance functional manifested as Carbohydrate Intolerance.

What path are You On?
- A University of Adelaide-led project has overturned the theory that the evolution of human intelligence was simply related to the size of the brain, but rather linked more closely to the supply of blood to the brain. (20) The blood flow diagram directly correlates to the above brain size diagram. (21) To allow our brain to be so intelligent, it must be constantly fed oxygen and nutrients from the blood. Dr. Snelling and Ms. Bosiocic say ... "Throughout evolution, the advance in our brain function appears to be related to the longer time it takes for us to grow out of childhood. It is also connected to family cooperation in hunting, defending territory and looking after our young".
- Cooking denatures the proteins in food, this process is similar to what the acids do in the stomach. Both processes disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape. Ileal studies have shown that cooking denatures proteins and makes them more bioavailable.. (8,22) Researchers have shown that digestability goes from 51 % to 90 % when cooked vs raw. The energetic benefit of cooking increases bioavailability by approximately 78%.. (22) PowerPoint slides. (23)
- Fasting has been practiced for millennia, but, only recently, studies have shed light on its role in adaptive cellular responses that reduce oxidative damage and inflammation, optimize energy metabolism, and bolster
cellular protection. In lower eukaryotes, chronic fasting extends longevity, in part, by reprogramming metabolic and stress resistance pathways. Human trials are about start, but in animals intermittent or periodic
fasting protects against diabetes, cancers, heart disease, and neurodegeneration, while in humans it helps reduce obesity, hypertension, asthma, and rheumatoid arthritis.
Thus, fasting has the potential to delay aging and help prevent and treat diseases while minimizing the side effects caused by chronic dietary interventions.
Additionally, fasting state to feeding state triggers stem cell regeneration and growth, and has been shown to generate new brain cells. (25) The formation, maintenance and reorganization of synapses are critical for brain development and the responses of neuronal circuits to environmental challenges. (26)
