9 Myths of the 21st Century We Should Get Rid Of

9  Myths of the 21st Century We Should Get Rid Of

Joseph Goebbels, the Nazi Minister of Propaganda, said that a lie repeated often enough becomes truth. And it is the only thing anyone in their right mind would agree with him about. It is amazing the crazy things that people are ready to believe in simply because they heard them many times; in this article we will take a look at 9 such myths.

1.     Humans Only Use 10% of Their Brains

Beliefs tend to persist based on how interesting rather than how correct they are. And in this respect, this one is a champion. No one knows who started it, but it probably originates from the fact that parts of the brain can be removed without causing any significant harm. However, different areas of the brain are specialized. You use one to discern faces, another to keep you upright and so on. There is actually no way to use the entire brain for a single task.

2.     Thomas Edison Invented the Light Bulb

We are used to thinking about Edison as a lone creator who made 10,000 attempts before succeeding in creating a light bulb. In reality, he had a 14-man team behind him who created several hundred patents, one of which was the light bulb. Edison’s name was more of a trademark than the name of the inventor.

3.     The Great Wall of China is the Only Man-Made Structure Visible from Space

It is wrong in several ways. Firstly, the Great Wall is not seen all that well – at least to an unaided eye from low-Earth orbit. Secondly, there is a number of other man-made structures that are, in fact, seen better, for example, the pyramids of Giza.

4.     Hair Grows Quicker in Zero Gravity

It is hard to say anything meaningful about this weird idea – it is just not true. Gravity doesn’t play any role in hair growth, so it continues to grow with the same speed in space.

5.     Sport Supplements Make You Pimply and Stupid

Name a horrible teenage problem, and it will be attributed to steroids. Decreased mental capacity, pimples, stunted growth – whatever you like. In reality, the truth about steroids is much more complicated. Some of these statements are completely false; others are greatly exaggerated. In a word, there is no proved connection between sport supplements and any of these consequences.

6.     You Can Kill a Virus

No you can’t, for the simple reason that virus isn’t alive per se. You can disrupt its reproduction cycle, you can put it to sleep, but  you can’t kill it.

7.     Seasons Caused by the Distance from the Sun

Distance from the Sun has very little effect on seasonal changes. In fact, the Earth is somewhat warmer when furthest from the Sun. This should be pretty obvious, really, for there is summer in northern hemisphere when there is winter in southern one and vice versa.

8.     One False Move and a Particle Accelerator Will Kill Us All

This was a big one back in 2008 when the Large Hadron Collider was about to be launched and doomsayers were sure that a black hole would destroy the Earth as a result. Just tell it to a physicist and listen to him laugh.

9.     Smoking Will Definitely Cause Cancer

We all know that smoking can cause cancer and have been told this from early childhood. But if it were 100% true that smoking always causes cancer, there wouldn’t be as many old people who have been smoking like chimneys for their entire life but don’t suffer any ill effects from it. Why is cancer so selective? Nobody knows.  In addition to that, one can greatly decrease even the proved health risks by using alternative variants of smoking, such as vaporizers.

Knowledge is the best vaccine against myths. Next time you hear one of these, you will know them for what they are.

12 Best Brain Foods That Improve Memory and Boost Brain Power

12 Best Brain Foods That Improve Memory and Boost Brain Power

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:

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!
