A new study reports that most of the healthy children and teenagers who take daily vitamin and mineral supplements probably don't need them, while the kids who would benefit from supplements are least likely to get them.
Most kids taking daily vitamin supplements already receive adequate nutrition from the foods they eat, and were healthier overall, have health insurance, and come from upper-income families, the researchers report. Meanwhile, kids who do need supplemental vitamins and are in fair or poor health — due to less healthy diets, less physical activity, higher obesity rates, less access to health care, and lower family income — might not get them. The American Academy of Pediatrics (AAP) does not recommend routine vitamin supplements for healthy children over 1 year old. Taken in large quantities, vitamin and mineral supplements can cause adverse effects ranging from vomiting to serious side effects, such as damage to the kidneys. Fat-soluble vitamins or minerals, for instance, which the body stores and excretes slowly, can build up to levels that could cause problems.
I agree that there's no need to take vitamin or mineral if kids eat a wide variety of foods, including whole-grain products, fresh fruits and vegetables, dairy products, nuts, seeds, eggs, and meats, then they're probably getting the vitamins and minerals they need.
My article is about the discovery of Methane in Mars.After five years of researches, scientists have now found and are sure that there is Methane is Mars. In Earth, Methane is used as a byproduct of living bacteria. But the scientists are still not sure of the cause of having Methane. In 2004, the scientists had some thoughts of having Methane, but this year they are sure of finding it. The scientists are still not sure of where does Methane come from, but some guesses think that it might be living off hydrogen produced by rock.
This is important because if the purpose of having Methanr in Mars was the same as in Earth, then life can exist. Methane is used in earth as a byproduct of living Bacteria.So after all of this reaserching the scientists can be sure of having life in Mars of not by finding why is there Methane in Mars. I also agree with this because there is nothing wrong with this discovery that can have any effecs on us or anything. And also I think that its very important and its one of the reasons of finding wheter there is life on Mars or not. A question that still cant be answered.=D
Second Hand Smoke Increases Hospital Admissions For All Types Of Infectious Diseases
Children exposed to second hand tobacco smoke are more likely to get severe infectious diseases and have to be admitted to hospital, finds research published online ahead of print in Tobacco Control. These children are at greater risk of a whole range of infectious illnesses, such as meningococcal disease, and not just respiratory illness, the results showed. Exposure to smoke in the first few months of life did the most harm, especially if they had a low birth weight or had been born prematurely. I believe this article is very important. We, human being, must avoid smoking in front of a child even in the surroundings. But unfortunately, Most of people in our society are thoughtless. Even parents, especially "FATHERS", which are directly concerned, smoke in front of their children thinking that nothing will arrive. In my concern, it's a pure selfishness.

Most of the childrens around the world fell an extreem fatiguein the first of the year, because the summer had just ended.your brain needs a chemical called dopamine to help you stay awake even though you are tired.Some scientists had just discovered that this chemical make your brain always thinking and does not make you tired.I think it is a good discovery and i wich they make a medicen that contain this chemical.
If you've ever been in a car that's traveling down a dirt road, you know how bumpy the ride can be. Dirt roads often develop ridges—and until recently, no one knew why. These bumps are usually several inches high, and they occur every foot or so. Workers can use bulldozers to flatten the dirt, but the ridges reappear soon after cars hit the road again.
Scientists have attempted to explain why ridges form, but their theories have been very complex. As a result, engineers haven't been able to put the theories to the test or to design bumpfree dirt roads.
Recently, researchers at the University of Toronto and their colleagues at the University of Cambridge in England attempted to come up with a simple explanation of why the ridges form.
They began by building a turntable—a round, flat surface that rotates, somewhat like the spinning surfaces sometimes found on large restaurant tables.
To make a model dirt road, the scientists covered the turntable with grains of dirt and sand. They placed a rubber wheel over the surface so that it rolled over the dirt as the turntable rotated.
In repeated tests, the scientists varied conditions in every way that they could think of. They used grains of different sizes and mixtures. Sometimes they packed down the dirt. Other times, they scattered the grains loosely on the surface.
The researchers also tested wheels of different sizes and weights. They even used a type of wheel that didn't spin. And they rotated the turntable at a variety of speeds.
Depending on conditions, the distance between ridges varied. But the ripplelike ridges almost always formed, regardless of what combination of factors the scientists used.
To better understand what was going on, the team created a computer simulation that showed how individual grains of sand move as a tire drives over them.
The computer program showed that dirt surfaces, even those that look flat, actually have tiny bumps. As a wheel rolls over these little bumps, it pushes the dirt forward a small amount. This nudge makes the bump get slightly bigger.
When the wheel then passes over the bump, it pushes dirt down into the next bump. After a hundred or so repetitions—not unusual for a well-used road—the bumps turn into a pattern of deep ridges.
Obesity is a condition of being overweight. This means eating stuff that is junk food. Being obese cause your stomach to stick out with fat. When you eat junk food which is like chips, cold drinks, candy, anything that contain too much sugar, chocolate …etc.
Being overweight is a bad thing. Everyone will keep making fun of you. Once u get used to eating and sneaking junk food u will never stop u will keep and keep eating those junk food with high calories.
I agree that being overweight is a bad thing and not good for your physical health
Tuberculoses Tuberculoses is a deadly disease that usually attacks the lungs although it can attack the central nervous system, the lymphatic system, the genitourinary system, the gastrointestinal system, and of course bones and joints etc. TB( tuberculoses) is often spread through the air, because people that have it cough, spit and sneeze....therefore people often catch it. Many people that get TB often end up dying.
I think this article is important because it is a common disease. It also tells you what the symptoms are so you can tell if you have TB. It is also important to know what TB actually does to your body!
I agree with this article, i think that yes, this is what TB does. I also think that this is how TB is spread, because it is contagious, thats why if someone that has it comes near you, you have to be careful. So yes i do agree with this article.
Marijuana Marijuana is also known as Cannabis, or ganga is a psychoactive drug taken out of the plant Cannabis Sativa. The herbal form of this drug consists of dried mature flowers and subtending leaves of pistillate (female plants). The resinous form known as hashish is made mostly of glandular trichomes collected from the same plant material. Humans have been taking cannabis ever since prehistory, although in the 20th century there was a rise in its use for recreational,religious,or spiritual, and medicinal purposes. It is estimated that about 162 million people use cannabis annually.
This article is important because it tells you what the meanings of marijuana are so you can watch our for it, what plants you can extract marijuana from, the population of people that use marijuana, and what other people call marijuana in other parts of the world that smoke it. I think that this article is also very important because it tells you to watch out for this very dangerous drug, and what the drug can do to you.
I agree with this article because it says a lot of information about marijuana, the names for it, how many people use it, what it can do to you, and what plants marijuana is taken from. All of the information in this article about marijuana is true and very good and informational.
Meryem Bousfiha My article is about the Life that can be after humans! Many people have asked what will happen to us humans in 100 years from now. The posthuman are people who think about life, humans and how they will change in the futur. They think that 'humans' is being a hard issue. The basic idea of posthuman is a human who once was human or his ancestor was a human but in the futur will change themselves from us and how we are today. Artificial organs can change now, which can change the texture or look of 'humans' as we are now. These artificial organs we replace by organs that are not working anymore.Nanotechnology combined by biology can lead us to replace these organs by even healthier and younger. So when can this person stop being human , they can just live on forever.Nanotechnology can also replace the neurons, and our organs that stop working! So you can just change them by even a healthier organ so there wont be any end for you !! In other words you wont die... I think its a very important article! With nanotechnology you wont die until you want to.... You can always change the dead or the organs that doesnt work properly by even better ones! Not only the organs but many other things!! So its very interesting to have an endless life, or a life when you can die until you decide to die... but it will be very boring to go on living and living :)! I think its pretty cool... =)
My article is about greener diet. The food we eat has affects on global warm=ing. Global warming makes the earth warmer because of the fuels that are released to the Earth. The green house gases warm the Earth more and more. The vegetables dont take any fuels and it doesnt hurt the environment at all. Its easy to grow and healthier. But on the other hand, the Beef affects our environment. The production of the meet releases a lot of carbon dioxide. Most of the carbon dioxide released comes from the meet productions. Unfortunatly, the meet is bad for the health somehow and it effects the environment.
I agree with this, and I have nothing wrong with it. Its not bad news at all for me since I dont like meet. I think that its better to eat vegetables and help the environment. Global warming affects our Earth a lot, animals will die and eventually the humans too. We have to decrease our diet from the beef meet. At least if will decrease the global warming a little bit. I THINK that its very important because global warming is a big problem to the world. AAnd so this meet affects our health as much as our environment... =D
