10 Things Only The Colorblind Would Understand

10 Things Only The Colorblind Would Understand

Most people dismiss colorblind people as having a minor problem with red and green. As we shall see below, color vision deficiency (CVD) is not as simple as that! About 8% of males (one in twelve men) have this condition while females suffer more rarely from it (5%). While it is normally an inherited condition, many people may suffer from it later on in life when it is caused by other illnesses such as diabetes or as a side effect of medication. Here are 10 things that the colorblind will understand only too well. It is much more than an eye health problem.

1. People think their world is only in black and white.

When people see the world in black and white, this is not the usual color blindness at all. It is a condition known as achromatopsia and sufferers see the world in different shades of grey. It is rather like viewing the world on an old black and white TV. Fortunately, this condition is very rare and about 1 in 33,000 people are affected.

2. People think the colorblind mix up red and green.

It would be great if it were that simple. They think that they just get their reds and greens confused. But, if you look at the actual cause of color blindness, it tells a different story. The eye has certain nerve cells, called cones, in the retina which can differentiate color. When this is defective, the eye fails to pick up the red elements so the colors of red and green appear to be the same color, a shade of light brown, in many cases. Another example of this red/green color blindness is that there is difficulty in seeing the red element in purple so they will have problems in distinguishing blue and purple.

3. People think it is a minor problem.

Many people dismiss color blindness as a minor disability. But the reality of life tells a different story. Colorblind people have difficulty when they do not realize their child may be getting sunburnt! They may have problems when gardening or when they have to prepare food, not to mention when buying clothes. Laying the table may become problematic when they select the ketchup instead of the chocolate sauce for the dessert. Glasses which can help block glare can usually help a little in better distinction of colors.

4. Colorblind children have problems with food.

Imagine telling a colorblind child to eat up his spinach. The problem is that it appears to him as a rather unattractive brown color which will remind him of something else which is totally disgusting. Similar problems arise when they have to distinguish between an unripe green banana and a nice yellow ripe one.

5. People think that colorblind people can adjust easily.

In many cases, colorblind people adjust and they can tell the difference between red and green traffic lights by their position. But, in many cases, their choice of career can be limited as they will have problems with colors. Becoming a fashion designer, graphic designer or an electrician are usually impossible for people with this condition.

6. Effects on the business and the economy are rarely taken into account.

It is only recently that the idea of changing colors in reports, graphs, presentations, brochures, colored house plans and maps to become more color-blind friendly has begun to make an impact. The truth is that all this colorful information may not be fully accessible for a small minority, around 10%. If the reds and greens are seen as brown, it may be impossible to fully understand a report, graph or a PowerPoint presentation.

7. Food marketing needs to take color blindness more seriously.

We seem to live in a red/green world. From traffic lights to the green economy and food packaging these two colors are everywhere! Let us take an example from supermarkets which use a red/green traffic light system which warn people of levels of fat, salt and sugar. A quick glance to spot the red colors which are unhealthy will do for most of the population. But for those who are suffering from CDV, then they have to read the actually detailed info on the label which is usually far too small anyway. This will affect about 5% of customers.

8. LED lights are infuriating.

Most warning systems use red and green to signal that a device is on standby. The red/green system is also used to indicate whether a battery needs charging. For the colorblind, this can be frustrating to say the least because they never know what is really happening. It is always the same old color!

9. Working in a safe environment is important.

Most employers have never even bothered to reflect on whether their premises are actually safe for the colorblind. Are the warning signs for health and safety using color as the main component? If they are, then this may lead to accidents. Health and safety authorities in the UK warn that under sodium lighting, red is not easily read by people with normal vision.

10. Using a computer with colorblindness.

British Telecom have issued a short guide for web designers to help make their pages more color-blind friendly. Keeping in mind such things as luminosity with background will make the text more readable. This is an excellent initiative because most web designers have never even taken this into consideration. It is high time they did!

Are you or a loved one color blind? How do you cope? Let us know in the comments.

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!
