Sugar: Can't Think Without It!
SUGAR: CAN’T THINK WITHOUT IT!!
A major secret of superior brain function is to eat in ways that give your brain cells steady access to desirable levels of blood sugar. Neurons cannot convert fat and protein into glucose. The brain consumes 20-30% of the body’s entire energy, and stores so little glucose that it uses it up in ten minutes if not replenished!
Glucose problems (too little OR too much) adversely affect memory, attention span, concentration, excitability, mood, as well as promote dementia and Alzheimer’s disease. Aging brains may need more glucose, as the ability to metabolize it can decline, thus the small storage capacity is decreasing.
Crucial glucose enters the blood mostly from consumption of carbohydrates. The body maintains a certain level of glucose in the blood specifically to serve the brain and central nervous system. Glucose is as much a lifeline as oxygen. It shares the same hazards as both can mutilate and destroy cells. In excess, both can be extremely toxic.
BLOOD SUGAR IS A MEMORY KEY
Creating moderate increases in blood sugar generally improves memory and learning. The harder you use your brain, the more important it is to have adequate blood and brain glucose. When your mind is most active, striving, learning, solving problems, you burn more glucose. Replenish it to continue to function at optimum levels.
BREAKFAST AND BRAINS
Non-breakfast-eaters are shown to be twice as apt to be depressed and four times as apt to have anxiety. Find creative paths to sneak your way into becoming a breakfast eater. Even a small breakfast will make a big difference.
SUGGESTIONS FOR NON-BREAKFAST-EATERS:
Note: I have recently altered this post as I learn more about glucose from Tim Ferriss' book, The 4-Hour Body. You may want to see my blog, This Extra Day, also available on Kindle. On that blog I go into detail about my new food plan and how it is affecting my blood sugar, my brain and my life.
In the 4-Hour Body food plan, breakfast starts with a big hit of protein - within an hour of waking. This is key to flattening out the sugar spikes. So, the adjustment I would make to the following suggestions is to eat two eggs first thing. Ferriss' research shows that people do not eat enough protein in the morning to start the day without going into a cycle of spiking blood sugar.
Black beans and salsa with your eggs
ALL THE DIFFERENCE
The kind of carbohydrates you eat will determine your outcome. This information has changed so radically in recent years you may have to overcome some beliefs in order to assimilate it.
LITTLE-KNOWN FACTS AND ODDITIES:
Interesting findings have emerged regarding combining foods. Vinegar, for example, depresses blood sugar and can save your brain from spikes. Four teaspoons added to an average meal is enough. (Potato salad with vinegar reduces GI 25%). All types of vinegar as well as lemon juice are effective. Acidity is the reason. Lactic acid also helps, which is why yogurt has a low GI even with sugar.
Sugar-damaged proteins turn yellowish-brown and are called advanced glycosylation end products (A.G.E.). The process is similar the browning a chicken where the skin gets crispy. We are all undergoing this browning process as we age. Research shows the main culprit in AGE is high glucose levels in the blood. Simple sugars appear to be the most damaging. A diet consistently high in simple sugars shortens lifespan and increases all the negative outcomes of brain aging.
White flour raises blood glucose faster than ice cream, and white potatoes raise blood glucose faster than pure sugar! Ouch.
HIGH FRUCTOSE CORN SYRUP is this culture’s most common culprit for the damage from simple sugars. Guess where high fructose corn syrup is most commonly found. You got it. Sodas. Even the “healthy” ones. Check the labels.
Take alpha-lipoic adic (50-100 mlg/day), along with chromium (200 mcg) to help normalize blood sugar.
Sweet blessings to you!
