Scientists Discover Why You Should Take Off Your Shoes Before Entering Your Home

Scientists Discover Why You Should Take Off Your Shoes Before Entering  Your Home

It was only when I had a Japanese guest visit that I realized the importance of taking off my shoes before entering the house. As many Japanese eat on tatami mats on the floor and sleep on futons that are rolled out at night, it seems perfectly logical to keep shoes at the door. In fact, this is the norm in most Asian countries. Yet, interestingly, many European and American families never bother to insist on leaving shoes at the door.

Now, science is backing up this hygienic practice and revealing that what you pick up on your shoes is not just a few germs and dirt, but rather nasty customers who should never be allowed into your home! This is particularly important when you have toddlers rolling around the floor.

Which nasty bacteria are you bringing home?

Researchers at the University of Houston found that about 40% of shoes were carrying the nasty “C.diff” bacterium, which stands for Clostridium difficile. These spores are not at all easy to treat.

The study found that this C.diff was not only on shoe soles (about 40% of the total examined), but also spread around other household areas such as toilets, tops and surfaces, and wherever floor dust was found. These spores can live on dry surfaces for a long time.

The problem with treating an infection caused by C.diff is that it is resistant to most antibiotics. This can cause the bacterium to proliferate and make recovery very difficult for the patient. The linings in the intestines are attacked, resulting in colitis. Many people in hospitals pick up the C.diff infection and it is becoming more difficult to treat.

Now, you don’t want this bacteria as a guest in your home, do you? Off with the shoes and on with the slippers.

What else is on those shoe bottoms?

Well, there will be a disgusting quantity of dust, bird droppings, dog poop, leafy debris and other unwanted matter. The leafy stuff acts as a breeding ground for bacteria.

“That means potentially harmful bacteria can survive on your shoes for days or even weeks.”- Dr. Reynolds, microbiologist, University of Arizona

The University of Arizona decided to assess the quantity of bacteria and they were not disappointed – they found 421,000 different units! These can be categorized into 9 different strains. They are the cause of infections in the eyes, lungs and stomach. Two of these are certainly worth mentioning so you can reach for your slippers the moment you get home.

The first one is known as E.coli (a pathogenic organism) and it makes up about a third of all bacteria so it is a heavyweight. E.coli strains are mostly harmless, thank goodness, but the nasty ones (like E.coli 0157:H7) are not. They often cause severe stomach and intestinal problems leading to vomiting and diarrhea. Now, you might think the risk of contacting the E.coli bacteria from your shoes is minimal. But let me ask you a question: How many times did you visit the restrooms at work today?

Another type of bacteria the researchers found was the Klebsiella pneumoniae which is known to cause severe damage to the lungs and lead to pneumonia. The death rate from this bacteria is high at 50% and can reach 100% when people are suffering from alcoholism.

What you can do to have a healthier and cleaner home

There are so many advantages in taking off those shoes and wearing slippers. You will have to clean the house less often and your floor coverings will last longer, thus saving you lots of money. Your shoes will last longer, too!

Keep a shoe rack or basket near the door so that everyone does it automatically, as soon as they get home.

Your house will be much healthier and cleaner. If you have toddlers, they can safely play on the floor and you need not worry about them. Another great advantage is that if you go barefoot, you will be stimulating your foot pressure points — for you reflexology enthusiasts. The Chinese have been doing that for 5,000 years!

Finally, your neighbors downstairs will start smiling at you again as they no longer hear the clip-clop of your shoes, up and down, morning and night!

But perhaps Al Franken put it best:

12 Best Brain Foods that Improve Memory

12 Best Brain Foods that Improve Memory

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!
