Extreme Environment Is What We Need If We Want To Stay Healthy

Extreme Environment Is What We Need If We Want To Stay Healthy

If you’ve watched Man vs. Wild, you must have gasped at what Bear Gryll does in the show. Taking baths in icy rivers, eating giant worms, sleeping unprotected in the wild…

It’s really hard to imagine how life would be if we were placed in such extreme environments, isn’t it? Living in the modern society, we seldom need to confront the elements. When summer comes, we can simply turn on the air-conditioners. In the winter, we can stay in our cozy homes with the protection of heaters.

The counter-intuitive approach to keep us healthy

While we’re counting our blessings, the American journalist and anthropologist Scott Carney puts forward a different view. In his recent book What Doesn’t Kill Us: How Freezing Water, Extreme Altitude, and Environment Conditioning Will Renew Our Lost Evolutionary Strength, Carney suggests that apart from exercise and diet, exposure to environmental stress, like extreme high and low temperatures, is the essential third pillar to keep us healthy.

What doesn’t kills you makes you stronger

Thinking what Carney says is counter-intuitive? Then you haven’t realized the fact that human body needs occasional physical challenges to maintain its optimal state. It is the modern sedentary lifestyle creates the illusion that we can’t endure the harsh conditions shown in Man vs. Wild.

Just as what Carney wrote in his book:

“With no challenge to overcome frontier to press, or threats to flee from, the humans of the millennium are overstuffed, overheated, and under-stimulated.”

Modern sedentary lifestyle is a sugar-coated poison

Actually, the surge of health problems like heart disease, type 2 diabetes and anxiety in this century has proven that the comfortable lifestyle we’re living is not desirable for our bodies. Degeneration comes when we consume too many processed foods and become oversensitive to trivial matters in life.

That’s why Carney advocates bringing environmental challenges back into our lives. He worked with Wim Hof, a Dutchman with the nickname of “Iceman” to conduct an experiment to see whether exposure to extremely cold environment can help bring our fitness to another level and heal us from injuries and diseases.

Although currently there is no concrete scientific evidence showing the effectiveness of Hof’s cold exposure therapy, Carney observed from Hof’s students that withstanding extreme cold weather helps relieve symptoms of Parkinson’s disease and Cohn’s disease.

12 Best Foods That Improve Memory and Brain Health

12 Best Foods That Improve Memory and Brain Health

Nutrition plays a vital role in brain function and staying sharp into the golden years. Personally, my husband is going through medical school, which is like a daily mental marathon. Like any good wife, I am always looking for things that will boost his memory fortitude so he does his best in school.

But you don’t have to be a med student to appreciate better brainiac brilliance. If you combine certain foods with good hydration, proper sleep and exercise, you may just rival Einstein and have a great memory in no time.

I’m going to reveal the list of foods coming out of the kitchen that can improve your memory and make you smarter.

Here are 12 best brain foods that improve memory and brain power:

1. Nuts

The American Journal of Epidemiology published a study linking higher intakes of vitamin E with the prevention on cognitive decline.[1]

Nuts like walnuts and almonds (along with other great foods like avocados) are a great source of vitamin E.

Cashews and sunflower seeds also contain an amino acid that reduces stress by boosting serotonin levels.

Walnuts even resemble the brain, just in case you forget the correlation, and are a great source of omega 3 fatty acids, which also improve your mental magnitude.

2. Blueberries

Shown in studies at Tuffs University to benefit both short-term memory and coordination, blueberries pack quite a punch in a tiny blue package.[2]

When compared to other fruits and veggies, blueberries were found to have the highest amount of antioxidants (especially flavonoids), but strawberries, raspberries, and blackberries are also full of brain benefits.

3. Tomatoes

Tomatoes are packed full of the antioxidant lycopene, which has shown to help protect against free-radical damage most notably seen in dementia patients.

4. Broccoli

While all green veggies are important and rich in antioxidants and vitamin C, broccoli is a superfood even among these healthy choices.

Since your brain uses so much fuel (it’s only 3% of your body weight but uses up to 17% of your energy), it is more vulnerable to free-radical damage and antioxidants help eliminate this threat.

Broccoli is packed full of antioxidants, is well-known as a powerful cancer fighter and is also full of vitamin K, which is known to enhance cognitive function.

5. Foods Rich in Essential Fatty Acids

Your brain is the fattest organ (not counting the skin) in the human body, and is composed of 60% fat. That means that your brain needs essential fatty acids like DHA and EPA to repair and build up synapses associated with memory.

The body does not naturally produce essential fatty acids so we must get them in our diet.

Eggs, flax, and oily fish like salmon, sardines, mackerel and herring are great natural sources of these powerful fatty acids. Eggs also contain choline, which is a necessary building block for the neurotransmitter acetylcholine, to help you recall information and concentrate.

6. Soy

Soy, along with many other whole foods mentioned here, are full of proteins that trigger neurotransmitters associated with memory.

Soy protein isolate is a concentrated form of the protein that can be found in powder, liquid, or supplement form.

Soy is valuable for improving memory and mental flexibility, so pour soy milk over your cereal and enjoy the benefits.

7. Dark Chocolate

When it comes to chocolate, the darker the better. Try to aim for at least 70% cocoa. This yummy desert is rich in flavanol antioxidants which increase blood flow to the brain and shield brain cells from aging.

8. Foods Rich in Vitamins: B vitamins, Folic Acid, Iron

Some great foods to obtain brain-boosting B vitamins, folic acid and iron are kale, chard, spinach and other dark leafy greens.

B6, B12 and folic acid can reduce levels of homocysteine in the blood. Homocysteine increases are found in patients with cognitive impairment like Alzheimer’s, and high risk of stroke.

Studies showed when a group of elderly patients with mild cognitive impairment were given high doses of B6, B12, and folic acid, there was significant reduction in brain shrinkage compared to a similar placebo group.[3]

Other sources of B vitamins are liver, eggs, soybeans, lentils and green beans. Iron also helps accelerate brain function by carrying oxygen. If your brain doesn’t get enough oxygen, it can slow down and people can experience difficulty concentrating, diminished intellect, and a shorter attention span.

To get more iron in your diet, eat lean meats, beans, and iron-fortified cereals. Vitamin C helps in iron absorption, so don’t forget the fruits!

9. Foods Rich in Zinc

Zinc has constantly demonstrated its importance as a powerful nutrient in memory building and thinking. This mineral regulates communications between neurons and the hippocampus.

Zinc is deposited within nerve cells, with the highest concentrations found in the hippocampus, the part of the brain responsible for higher learning function and memory.

Some great sources of zinc are pumpkin seeds, liver, nuts, and peas.

10. Gingko Biloba

This herb has been utilized for centuries in eastern culture and is best known for its memory boosting brawn.

It can increase blood flow in the brain by dilating vessels, increasing oxygen supply and removing free radicals.

However, don’t expect results overnight: this may take a few weeks to build up in your system before you see improvements.

11. Green and Black Tea

Studies have shown that both green and black tea prevent the breakdown of acetylcholine—a key chemical involved in memory and lacking in Alzheimer’s patients.

Both teas appear to have the same affect on Alzheimer’s disease as many drugs utilized to combat the illness, but green tea wins out as its affects last a full week versus black tea which only lasts the day.

12. Sage and Rosemary

Both of these powerful herbs have been shown to increase memory and mental clarity, and alleviate mental fatigue in studies.

Try to enjoy these savory herbs in your favorite dishes.

When it comes to mental magnitude, eating smart can really make you smarter. Try to implement more of these readily available nutrients and see just how brainy you can be!
