What Is the Brain's Preferred Fuel?
What is the best possible fuel that you can feed your brain? For many decades now, scientists and some nutritional experts have believed that glucose is the number one fuel for the human brain. But recent research and nutritional studies say that this might not be the case. Today we're going to look over the facts and help you figure out which is the best brain fuel for your health, wellness, and cognitive longevity.
Glucose as Brain Fuel
For the longest time, researchers believed that the brain ran on glucose, and glucose alone. They also believed that feeding your body large amounts of carbohydrates all day, when paired with a healthy exercise routine, could help with brain function. Unfortunately, the development of diseases like Alzheimer's in recent years have forced researchers to go back to the drawing board and take a closer look at how the brain manages its energy needs. And it turns out that the brain's relationship with glucose is a little more complicated than we once thought.
Yes, it's true that certain parts of the brain can only run on glucose alone. But much of the brain can run on different types of fuel (referred to as "substrates" in the literature), including ketones. And those parts of the brain that require glucose don't need all that much - most people's brains are happy and healthy over the long term running on between 100g and 150g of glucose a day.
On top of all this, recent science has discovered that human beings don't need to eat exogenous glucose in order to get the glucose their brain needs to thrive. The body has its own protective mechanisms for producing glucose when your blood sugar gets low. It's something called gluconeogenesis. It happens when your liver converts amino acids from protein into glucose so that your brain can burn them for energy. As long as you have plenty of protein to spare and a healthy metabolic response, your body is fully capable of making all the glucose your brain needs for optimal focus and memory retention.
Unfortunately, eating excess amounts of carbohydrates - especially from highly processed foods - has a strange, converse way of inhibiting this process. Too many refined carbs have a way of spiking your blood sugar and overloading your brain cells to the point where they can't process glucose anymore. In the short-term, this results in brain fog, mental fatigue, mood swings that coincide with blood sugar crashes, and poor cognitive function. Over the long-term, you may leave your brain more vulnerable to developing diseases like Alzheimer's or dementia.
Long story short: moderating your glucose consumption and keeping your blood sugar low and stable is the best way to maintain optimal brain function over the long-term. This requires you to keep your carbohydrates in check so that your brain makes more of its own glucose from the food you eat instead of scrambling to play gatekeeper and keep excess glucose out to preserve neuronal function.
Ketones as Brain Fuel
When your blood sugar dips below a certain level, there's another protective mechanism your liver engages in order to protect the brain and keep it filled between meals: it produces endogenous ketone bodies. The idea of ketone bodies and ketosis in general scares most people because it flies in the face of conventional nutritional wisdom. After all, your body has to "go into starvation mode" in order to produce them. So how can they be good for you - or even better for you than running your brain on glucose, as some medical experts are starting to suggest?
Well, there's actually over a hundred years of evidence suggesting that ketones are good for your brain - especially if you suffer from epileptic disorders. There's also the fact that government recommendations and nutritional science have been heavily influenced by corporate money over the last several decades - so this idea that you have to eat frequent meals loaded with carbohydrates in order to keep your brain fueled might not have as much to do with science as it does corporate profits. Then there's the fact that ketones are a cleaner, more efficient fuel source and produce fewer inflammatory byproducts as a result of their metabolism than glucose does.
There is also scientific evidence to suggest that brains which run on ketones switch on genes that tell your hippocampus to produce more mitochondria in your brain cells. Why is this important? Because brains from seniors who suffer from age-related dementia show a drastic loss of living brain cells in the hippocampus as the disease progresses. Producing more mitochondria in these cells, on the other hand, keeps them alive and healthier for longer. And in case you forgot, the hippocampus is the part of your brain which is essential for learning and memory. Without a healthy and thriving hippocampus, you can't learn new things, make new memories, or hold onto old ones. So feeding your brain with ketones can help keep your hippocampus healthier for longer.
The Best Brain Fuel: Constant Focus
At the end of the day, the best fuel for your brain is a whole food diet with fats, proteins, and carbohydrates from healthy sources. The more organic and minimally processed, the better. But if you really want to give your brain that extra edge, you should also be fueling it with a nootropic supplement like Constant Focus.
It has vitamins and nutrients that you won't find hardly anywhere else. It has them in just the right quantities that your brain needs to derive the maximum amount of energy it can from your food - whether you're running on glucose, ketones, or any other substrates. There are thousands of happy customers with better memories and sharper focus who swear by Constant Focus as their number one brain boosting natural supplement.
