Boosting Your Brain Power
The old theory that DNA could not be changed and that you would be stuck with what you were born with has now been disproved. Researchers found that your DNA actually changes continuously based on your experiences, emotions, and environment.
Our views of the brain have also altered in a similar way as our views of DNA. Science has now provided more and more evidence that your brain is malleable and adapts continuously in response to your lifestyle, physiology, and environment. This concept is called neuroplasticity or brain plasticity, meaning you are literally reforming your brain with each passing day. Your brain possesses the remarkable ability to reorganize pathways, create new connections, as well as neurons (nerve cells) throughout your entire lifetime.
For example, your brain has the ability to move functions from a damaged area to undamaged areas. It also has the ability to change its physical structure as a result of learning. When you acquire a new skill, the more you focus and practice it, the better you become. This is the result of new neural pathways that form in response to your learning efforts.
In the meantime, your brain also undergoes “synaptic pruning”, the elimination of pathways that you no longer use. This phenomenon even applies to emotional states. For instance, if you have a history of anxiety, your neural pathways will become wired for anxiety. However, if you develop tools to feel calm, relaxed, and peaceful, those anxiety pathways will be pruned away from lack of activity.
Consequently, you can see that your brain’s plasticity is highly affected by your way of life. The foods you eat, how much physical activity you have, your emotional states, and sleep patterns all have an influence over how your brain functions. Therefore, there is much that you can do to preserve or even boost your brain power. The following are key factors that will greatly affect your brain’s performance:
1. Link Between Gut Inflammation And Brain Inflammation
The fundamental mechanism that underlies chronic diseases, including the ones related to the brain like autism, Alzheimer’s, anxiety, depression, multiple sclerosis, and Parkinson’s, is the process of inflammation. Current science is strongly supporting that this process of inflammation actually begins in the gastrointestinal tract, which subsequently spreads to affect the brain.
What are the instigators behind gut inflammation? To the surprise of many, it is predominantly dietary –
The mistake of eating too many carbs resulting in chronic high blood sugar levels. Blood sugar elevation raises the binding of glucose to protein. This process, known as glycation profoundly increases the amount of inflammation in the body.
Opting for a low-fat diet, eating the wrong types of processed, rancid fats, or too few healthy fats.
Insufficient intake of antioxidants, which are mostly found in fruits, vegetables, and herbs.
Consuming too much foods loaded with irritants and toxins, such as chemicals, preservatives, pesticides, GMOs, and heavy metals.
Having undiagnosed sensitivity to gluten (a protein found in wheat, rye, and barley) and other foods such as dairy, eggs, and corn.
Candida yeast overgrowth, small intestinal bacterial overgrowth (SIBO), and intestinal parasites all trigger the immune response and lead to gut inflammation.
Inflammation is the body’s natural defense against something it believes to be potentially harmful. For instance, if you sprain your ankle, the body will sense some kind of stress going on. The natural response is to create swelling and pain to reduce movement and promote healing. These are the hallmarks of the inflammatory process; in small doses, it is not a negative thing.
It only turns bad when inflammation gets out of control and becomes chronic. Chronic inflammation is typically low-grade, silent, and produce no symptoms. When the body is constantly under assault, the inflammation response stays on and it spreads to every part of the body through the bloodstream. The brain is particularly susceptible as it is also connected to the gut via the vagus nerve.
Unchecked inflammation results in the production of a variety of inflammatory chemicals called cytokines which are toxic to the cells. The cytokines travel throughout the body causing oxidative stress, leading to a reduction of cellular function and even cellular destruction, and resulting in actual loss of function in the body. Studies using new imaging technology showed dramatic elevation of inflammatory cytokines in the brains of Alzheimer’s patients and individuals with other brain disorders. Hence, to prevent brain inflammation, the foremost is to maintain a healthy gut.
2. Foods That Feed The Gut And The Brain
The reason why inflammation is so rampant in western civilization is the modern diet. It is high in foods that provoke inflammation, such as refined flour, excess sugar, oxidized or rancid fats, trans fats, plus a wide range of chemicals and preservatives. And it is low in foods that reduce inflammation, like long-chain omega-3 fats, fermented foods, and fermentable fiber.
The following are some foods that are particularly beneficial to the gut and the brain:
Bone broth (used for healing the gut lining damaged by inflammation)
Coconut oil (used as an alternative fuel for the brain, other than glucose)
Chocolate, dark only
Fermented foods (rich in beneficial bacteria to keep the gut healthy, e.g. kimchee, sauerkraut, pickled vegetables, yogurt, and fermented drinks like kefir and kombucha)
Fermentable fiber (used as food for the good gut bacteria, e.g. asparagus, artichokes, garlic, jicama leeks, and onions)
Olive oil, extra virgin
Green, leafy vegetables
Wild caught Alaskan salmon
3. Exercise To Reduce Inflammation
While bouts of exercise tend to promote acute inflammation, when done regularly over the long term, it actually decreases chronic inflammation. The oxidative stress from the exercise forces your body to build up your antioxidant defenses. This is indicated in studies showing extended exercise programs help reduce inflammatory markers, such as insulin resistance (a risk factor for diabetes) and high sensitivity C-Reactive Protein (an indicator of cardiovascular disease).
However, some people tend to over exercise and it is extremely important to allow for sufficient recovery, especially when doing High Intensity Interval Training (repeated sprints interspersed by recovery). If you over-train, as in marathons, you may do more harm than good since your body needs to recuperate from the damage (acute inflammation) incurred during your workout.
The average American adult spends about 10 hours each day sitting. Research shows that this level of inactivity cannot even be counteracted with a 60-minute workout at the end of each day. So, what do you do if you have a desk job?
Know that the body needs near-continuous movement throughout the day. At the bare minimum, you should get out of the chair every 50 minutes or so and walk around.
One way to increase activity is to simply walk more. It is recommended that you aim for 7,000 to 10,000 steps a day. A fitness tracker will be a useful tool to help you meet your daily goal.
4. Lack Of Sleep Impairs Brain Function
Sleep deprivation is really bad for brain function. Many studies show that sleep loss impairs various cognitive functions and behavior, including arousal, attention, cognitive speed, memory, emotional intelligence, and decision making.
Using brain imaging technology, like functional magnetic resonance imaging (fMRI), scientists compared the brain of someone who was sleep-deprived to the brain of someone who had slept normally. They found reduced metabolism and blood flow in multiple brain regions which indicated impaired cognitive function and behavior.
Several nights of poor sleep or one night of no sleep will start to disrupt your hormonal balance. According to a study from Stanford University, your body’s ghrelin levels, which stimulate feelings of hunger, can jump nearly 15 percent. It also lowers your levels of leptin, a hormone that regulates energy balance, which explains why you tend to feel sluggish when you are sleep-deprived.
Your brain also struggles to curate and sort new memories. You are able to absorb new information but your brain has problems accessing that information and putting it to good use. You may feel distracted, while your reaction time plummets. This makes tasks like driving more difficult and dangerous.
A CDC survey shows that half of Americans (48%) do not get enough sleep. So if you want your brain to stay at tip-top shape, you need to place sleep high on your priority list. In the event that you just cannot get enough nocturnal sleep, a 30-minute nap at lunch time is still helpful although it cannot fully eliminate the negative consequences of sleep deprivation.
5. Vitamin D May Save Your Brain
Much has been learned about the health benefits of vitamin D over the past decade. While it has long been recognized that vitamin D supports strong and healthy bones, its role in brain-related disorders is becoming increasingly evident.
A new study that collaborated multiple highly respected institutions around the world found a profound correlation of low vitamin D level and increased risk of developing dementia. Even having a moderate deficiency of vitamin D was associated with a 53% increased risk of dementia. Those who were severely deficient had a 122% increased risk!
Many people are not aware that vitamin D deficiency is associated with increased inflammation. There are about 30,000 genes in the body, and vitamin D affects nearly 3,000 of them. Your brain has vitamin D receptors too. Therefore, unless you get 20 minutes of sun exposure daily (without using sunscreen on face, arms, and legs), you may want to consider supplementation.
Most people need around 5,000 I.U. a day to reach the optimal level of 50-70 ng/ml as determined by a blood test. If you supplement, opt for vitamin D3, which is the natural form, and take it with vitamin K2, with at least 100 mcg of menaquinone-7 (MK-7). The combination of D3 and K2 will make sure that calcium is deposited in the bones instead of the arteries.
6. Think Positive And Stimulate Your Brain
Stress and anxiety kill existing brain neurons and stop new neurons from being created. Research has shown that positive thinking speeds up the formation of cells and dramatically reduces stress and anxiety. Hence, catch yourself when your negative thoughts surface, discard them, and replace them with positive ones.
When you learn or do new things, new neural pathways are developed. As a result, you want to stimulate your brain on a continuous basis. Remember the phrase – use it or lose it?
