Glucose Quotes

Then there are the metabolic costs of switching itself that I wrote about earlier. Asking the brain to shift attention from one activity to another causes the prefrontal cortex and striatum to burn up oxygenated glucose, the same fuel they need to stay on task. And the kind of rapid, continual shifting we do with multitasking causes the brain to burn through fuel so quickly that we feel exhausted and disoriented after even a short time. We've literally depleted the nutrients in our brain. This leads to compromises in both cognitive and physical performance. Among other things, repeated task switching leads to anxiety, which raises levels of the stress hormone cortisol in the brain, which in turn can lead to aggressive and impulsive behaviors. By contrast, staying on task is controlled by the anterior cingulate and the striatum, and once we engage the central executive mode, staying in that state uses less energy than multitasking and actually reduces the brain's need for glucose. ~ Daniel J. Levitin

The brain is provided with a number of enzyme systems which serve to co-ordinate its workings. Some of these enzymes regulate the supply of glucose to the brain cells. Mescalin inhibits the production of these enzymes and thus lowers the amount of glucose available to an organ that is in constant need of sugar. When mescalin reduces the brain's normal ration of sugar what happens? Too few cases have been observed, and therefore a comprehensive answer cannot yet be given. But what happens to the majority of the few who have taken mescalin under supervision can be summarized as follows ... ~ Aldous Huxley

But our brains are different from mice. Their cortex is tiny, which means their ability to learn from experience is tiny. They are built to run on innate rather than learned circuits. Our cortex is huge because we are designed to fill it up with acquired knowledge. We are not meant to run on pre-loaded programs. Every creature in nature runs on as few neurons as possible because neurons are metabolically expensive. They consume more oxygen and glucose than an active muscle. It takes so much energy to keep a neuron alive that they actually make it harder to survive. Neurons only promote survival if you really get your money's worth out of them, by wiring them up with survival-relevant information. Natural selection gave humans a gargantuan number of neurons. That means we were meant to use the experience we've stored in our neurons, not to ignore ~ Anonymous

The brain's preferred source of fuel is glucose/carbohydrates. And when you go on a low-carb/high-protein diet, your brain is using low-octane fuel. You'll be a little groggy, a little grumpy. ~ Jack LaLanne

The leaves of the world comprise countless billion elaborations of a single, simple machine designed for one job only – a job upon which hinges humankind. Leaves make sugar. Plants are the only things in the universe that can make sugar out of nonliving inorganic matter. All the sugar that you have ever eaten was first made within a leaf. Without a constant supply of glucose to your brain, you will die. Period. Under duress, your liver can make glucose out of protein or fat – but that protein or fat was originally constructed from a plant sugar within some other animal. It's inescapable: at this very moment, within the synapses of your brain, leaves are fueling thoughts of leaves. ~ Hope Jahren

The production and consumption of glucose, and hence, the blood sugar level, are controlled by a functional endocrine equilibrium. ~ Bernardo Houssay

As this research had now made clear, the critical molecules determining the balance of storage and mobilization of fatty acids, of lipogenesis and lipolysis, are glucose and insulin - i.e., carbohydrates and the insulin response to those carbohydrates. ~ Gary Taubes

For diabetes in particular, we know there's a relationship between lack of glucose regulation and complications like blindness and kidney failure. So if you were diabetic and you knew that you could get your glucose in a tight, normal range just by adjusting your lifestyle, wouldn't that be great? ~ Eric Topol

No matter how closely you examine the water, glucose, and electrolyte salts in the human brain, you can't find the point where these molecules became conscious. ~ Deepak Chopra

carbohydrate controls insulin; insulin controls fat storage. Carbohydrates are not used as structural components in the body; instead, they are used only as a form of fuel, whether burned immediately while passing by different organs and muscles, or stored for later use. All forms of carbohydrates you eat, whether simple or complex, are eventually converted into glucose, ~ Mark Sisson

Researchers have reported that the brain and central nervous system actually run more efficiently on ketones than they do on glucose. ~ Gary Taubes

When your liver and muscles become filled with glycogen, any glucose remaining in the bloodstream that isn't used in "real time" by your brain or muscles (such as during an intense workout) gets converted into triglycerides in the liver and sent to fat cells for storage. ~ Mark Sisson

Your brain is the "greediest" organ in the body; the resting brain uses oxygen and glucose at 10 times the rate of the rest of the body. Thus, even though the brain makes up less than 2.5 percent of total body weight, it is responsible for 20 percent of the body's energy consumption. ~ Patricia Wolfe

Seeing your glucose every minute on your phone, it really changes your lifestyle. You ask yourself, 'Do I really need that piece of cake? No, because I don't want to stress out my pancreas.' ~ Eric Topol

Tightly focused attention gets fatigued - much like an overworked muscle - when we push to the point of cognitive exhaustion. The signs of mental fatigue, such as a drop in effectiveness and a rise in distractedness and irritability, signify that the mental effort needed to sustain focus has depleted the glucose that feeds neural energy. ~ Daniel Goleman

No other tissue in the body relies solely on glucose for energy except the testes. (This is why men occasionally experience a battle for resources between their brains and their glands.) ~ Daniel J. Levitin

Anything that works to transport more glucose into the fat cells - insulin, for example, or rising blood sugar - will lead to the conversion of more fatty acids into triglycerides, and the storage of more calories as fat. ~ Gary Taubes

Sweetness was a sign that a plant was edible (most plants that are poisonous to humans taste bitter). Sweetness is also an indication that the plant is high in glucose, which meant that it would offer us lots of energy. ~ Cameron Diaz

Our ancestors relied upon their advanced brains to survive during times of food shortage, and fortunately, the human brain is able to utilize body fat as an extremely efficient fuel to sustain function when glucose-providing food is unavailable. ~ David Perlmutter

So, in contrast to what you may have been led to believe, eating fat doesn't make you fat. Insulin is the primary hormone that drives the storage of fat in the fat tissues. And insulin is released not in response to dietary fat, but in response to dietary glucose. And the primary source of glucose in the modern diet is grain. ~ Josh Turknett

The baby, as I had reason from experience to expect and had in fact prepared my bag for, suffers from dehydration. He's dried up like a prune. The treatment is simple and the results spectacular. Slip a needle in his scalp vein and hang a bottle of glucose ~ Walker Percy

Shel Israel has been a diabetic for many years, jabbing his finger a few times every day to measure his blood sugar. Every six months he brings his glucose meter to his endocrinologist, who extracts and analyzes the data. His pharmacist recently informed him that a new California law requires him to share his data with them as well or his insurance coverage will be dropped, raising the monthly cost from about $8.25 to about $165. Who is behind this law? ~ Robert Scoble

Eating cholesterol and bad fat will contribute to heart disease if and only if you bathe them in a massive lifelong overdose of insulin and glucose. ~ Mark Sisson

In fact, according to physicians, the functioning of the digestion depends less on the brain than on hormonal mechanisms and autoregulators. However, during a fast, the digestive system gets an increasing rest. About ten hours after a meal, the contractions stop and the feeling of hunger disappears; five or six hours later the glucose stops coming directly from the intestines and begins to produce itself from the reserve of glycogen contained in the liver. From then on, the body works on itself in a closed circuit, becoming itself the source of the energy it uses. Instead of destroying an appropriating to himself nourishment taken from outside, man enters a state of nonviolence and detachment relative to the outside world. ~ Adalbert De Vogue

Intuitive errors are normally much more frequent among ego-depleted people, and the drinkers of Splenda showed the expected depletion effect. On the other hand, the glucose drinkers were not depleted. Restoring the level of available sugar in the brain had prevented the deterioration of performance. ~ Daniel Kahneman

…Sugar has become an ingredient avoidable in prepared and packaged foods only by concerted and determined effort, effectively ubiquitous. Not just in the obvious sweet foods (candy bars, cookies, ice creams, chocolates, sodas, juices, sports and energy drinks, sweetened iced tea, jams, jellies, and breakfast cereals both cold and hot), but also in peanut butter, salad dressings, ketchup, BBQ sauces, canned soups, cold cuts, luncheon meats, bacon, hot dogs, pretzels, chips, roasted peanuts, spaghetti sauces, canned tomatoes, and breads. From the 1980's onward manufacturers of products advertised as uniquely healthy because they were low in fat…not to mention gluten free, no MSG, and zero grams trans fat per serving, took to replacing those fat calories with sugar to make them equally…palatable and often disguising the sugar under one or more of the fifty plus names, by which the fructose-glucose combination of sugar and high-fructose corn syrup might be found. Fat was removed from candy bars sugar added, or at least kept, so that they became health food bars. Fat was removed from yogurts and sugars added and these became heart healthy snacks, breakfasts, and lunches. ~ Gary Taubes

The fact that early languages, no matter how many there are, utilize the same streams implies that the brain doesn't have a native language. The brain can only reflect the fact that a set of neural circuits was built and activated for a certain period of time. Nor does the brain care if those neural circuits map onto things that the rest of the world calls languages or dialects. It really cares only about what activates those circuits. Thus, the brain patters that typify language use across skill levels can be mapped.

Brain imaging technology monitors the intensity of oxygen use around the brain - higher oxygen use represents higher energy use by cells burning glucose. The deeply engrained language circuits will create dim MRI images, because they are working efficiently, requiring less glucose overall. More recently acquired languages, as well as those used less frequently, would make neural circuits shine more brightly, because they require more brain cells, thus more glucose. ~ Michael Erard

common table sugar, or sucrose, is a carbohydrate made up of two simple sugars, fructose and glucose. All plants produce sucrose, but a few contain very large quantities. Natives in the land now called New Guinea, the massive island north of Australia, discovered a tropical grass that came to be known as sugarcane, perhaps around 8000 BC. The sweet-tasting stalks were eventually carried to other lands, including India, where juices pressed from sugarcane were first boiled to produce crystals. Darius ~ Richard J. Johnson

Insulin works to deposit calories as fat and to inhibit the use of that fat for fuel. Dietary carbohydrates are required to allow this fat storage to occur. Since glucose is the primary stimulator of insulin secretion, the more carbohydrates consumed - or the more refined the carbohydrates - the greater the insulin secretion, and thus the greater the accumulation of fat. "Carbohydrate is driving insulin is driving fat," as the Harvard endocrinologist George Cahill recently summed it up. ~ Gary Taubes

Your pancreas, however, because of Metabolism B, releases excess insulin to deal with the bagel's glucose rush. Once this insulin helps to refill the glycogen stores in your muscle and liver, the excess keys will open excess fat cells. In an effort to feed these fat cells, you will dip into your normal blood sugar, leaving too little glucose left in the bloodstream to keep up your energy and sense of satiation. Your blood glucose has now dipped below the normal range. And so, after eating exactly the same meal, you will end up "fatter" than your friend and with lower blood glucose than she has! ~ Diane Kress

Your soul: pure glucose edged with hints
Of tentative and half-soiled tints ~ Edith Sitwell

If the young man ate candy, the wrangler says, that's probably what's kept him alive so long. Glucose is a natural antidote to cyanide poisoning. Based on anecdotal evidence, glucose binds with
the cyanide to produce less toxic compounds. ~ Chuck Palahniuk

From the 1980s onward, manufacturers of products advertised as uniquely healthy because they were low in fat or specifically in saturated fat (not to mention "gluten free, no MSG & 0g trans fat per serving") took to replacing those fat calories with sugar to make them equally, if not more, palatable, and often disguising the sugar under one or more of the fifty-plus names by which the fructose-glucose combination of sugar and high-fructose corn syrup might be found. Fat ~ Gary Taubes

The medical nanobots in my novel 'Small Miracles' tap the energy sources that the patient's own body provides. That is, they can metabolize glycerol and glucose, just as the cells in our bodies do. ~ Edward M. Lerner

A new laboratory technique, positron emission tomography, uses radioactively labeled oxygen or glucose that essentially lights up specific and different areas of the brain being activated when a person speaks words or sees words or hears words, revealing the organic location for areas of behavioral malfunction. ~ Floyd Skloot

I wear a continuous glucose monitor when I'm racing. ~ Charlie Kimball
