The Danger of the Food Additives

post by xiaoqichen

Which food additives add in the food

Food additives are substances added to food to preserve flavor or enhance its taste and appearance. Some additives have been used for centuries; for example, preserving food by pickling (with vinegar), salting, as with bacon, preserving sweets or using sulfur dioxide as in some wines. With the advent of processed foods in the second half of the 20th century, many more additives have been introduced, of both natural and artificial origin. The current society food additives were used extensively. They make the food to be delicious and to keep a long time. But if the food additives use too much it will be harmful to our health.

There are many food additives in the food. There are “Artificial Sweeteners, Monosodium Glutamate,Trans Fat Sodium Sulfite Sodium Nitrite” and so on these are usually to use in the food. Sodium Sulfite is a kind of preservative, it usually use in wine-making and other processed foods.The majority of these individuals are asthmatic, suggesting a link between asthma and sulfites. Individuals who are sulfite sensitive may experience headaches, breathing problems, and rashes. In severe cases, sulfites can actually cause death by closing down the airway altogether, leading to cardiac arrest. Thought It look very dangerous, but it has to used it. Because it make the food to keep a long time.

Thought the food additives are allowed to used but we don’t know what food additives would be added in the food. As we all know many food additives is dangerous for the health. For example Partially Hydrogenated Vegetable Oil is usually usthe-truth-about-food-additivesed in the fast food Partially Hydrogenated Vegetable Oil is a semi-solid fat created when food processors force hydrogen into unsaturated fatty acids. Partially hydrogenated fats are the principle sources of trans fat in the American diet, that is fast food. The good news: Partially hydrogenated oils are beginning to slowly retreat from our food. Progressive jurisdictions like New York City are starting to restrict the allowable amounts in restaurants, and many chains are switching to healthier frying oil, but some merchant maybe cut down the cost still to use the partially hydrogenated fats. Thought it is nontoxic, if the human eat over the limit that trans fat causes heart attacks. So I think it is harmful to the health. Actually much puffed food for example chips, the most part is oil, about 30% is oil, it is very unhealthy. But it is delicious, and many Youngers like the chip. It can cause the person to be fat. So I suggest the Youngers decrease to eat chip time. And you will have a rule habit to eat the food.

The incorrect use the food additives make person to die

The current there are many events about the food poisoning to cause the person die. And then we will know a kind of the dangerous food additives. Why when person would die with the food additives the media will tell the truth in the event. 2008 Chinese milk scandal) is China’s food safety incidents together. Incident involved a lot of eating Sanlu baby milk powder produced was found to have kidney stones, followed by chemicals melamine were found in its milk powder. According to published figures, as of September 21, 2008, due to the use of infant formula and outpatient rehabilitation therapy counseling and has accumulated 39,965 infants who are hospitalized have 12,892 people, 1,579 peou=2675094783,1537680858&fm=21&gp=0ple had been cured, death four people, As of the September 25, there are five people in Hong Kong, Macao people have a diagnosed illness. It is severity event. The melamine is a kind of the food additives. But it is a harmful additive. It can`t used in the food. The supplier used it in the milk. They cut down the cost but many children would die with these milk. The food additives make the people to die. I think the food additives must be pass detection for innocuity of the health. The current show much compound food. Used the chemistry additives compound food taste. For example used the chemistry additives chicken change taste makes it to become beef taste. It has possibility to realize. I think it is very grand on the diet. But they are harmful on the health. The first is carcinogenic problem. Such as certain artificial sweeteners, colorings and other tests confirmed the animal carcinogenicity. Such as butter yellow pigment can be induced liver cancer in rats, sweeteners glargine and phenyl urea can cause animal tumors. In recent years, also found in food coloring agent sodium nitrite, amine and meat, fish react to form a strong carcinogenic nitroso compounds. The then is Acute and chronic toxicity problems. Because the manufacture of additives impure and contaminated materials used several toxic compounds, causing people to acute and chronic poisoning. These two are big problems in the food additives. After all, is not a natural food additive food ingredients, such as improper use of the additive itself or mixed with some harmful ingredients, it may bring some harm to human health. Thought the food additives isn`t Illegal additives, the food additives must control use. Even if Add food additives legally harmless, but also not good for health

The current the Youngers` health is not very good before. The Diabetes and Subhealth show the low age people. Because these people do the work very busy and they eat the food not very rule. So their health are not vFood-Additives-Examplesery good and then the food that they use the food additives is not any nourishment. They aren’t any helpful to them become heartier. So I think the food use less the food additives. I didn’t think that using the food additive is mistake. After all they are not good for our health.

Food additives for improving food color, smell, taste and other quality, as well as the need for preservation or processing of the compounds into food quality or natural substances. So I think it is grand, the food additives must manage in the law and must pass the detection. All the food additives write the back of the packaging. The customs safety to buy this goods.

We spend most of time doing our things almost every day. Just like little bees, focus on our little cycle. cellphone text, daily talk, social networking, video games, websites… All of those things even let us forget how beautiful the world is. We really need consider about our life again now, before every thing get too late… Consider about how should we live our short life with no regret at the end…

Anyone who has some interests in cars or automobiles will know Formula One World Championship. There is no doubt that it is the fastest motor sports in the world. In 2007 the fastest F1 car can reach the top speed at 257.88mph, which is about 415 km/h. A Boeing 747 airplane’s take off speed is only around 280~300 km/h. It is a car which can go faster than a plane. When you seat at the auditorium, watching these fancy cars driving pass in front of you at an incredible speed, that kind of excitement is far beyond anything could ever bring to you. And of course the best part of the F1 is not only because of its speed, but also because of its sound. Since the speed of F1 is so fast, F1 cars will certainly have a big engine. In the early 50s one of the F1 team even developed a 1.5 liter V16 engine, it is an engine which has 16 cylinders! A normal sedan car has a 4 cylinders engine, some sports cars will have a 6 or 8 cylinders engine, and only the super car has 10 or 12 cylinders engines. But a 16 cylinders engine, all I could say is this kind of engine has ever been used in a mass-produced vehicle. Such big engine could sing a wonderful song which you have even heard. Even though the FIA, which is the management organization of F1, restricted this kind of engine couple years later. But the engine could still make a very nice sound to enjoy. So for many years F1 engine can play a fantastic symphony for the audience, but this year it could not play it any more.

It is because this year FIA made some changes about the rules, the biggest one is that all the F1 cars must use a 1.6 liter turbo charged V6 engine instead of a 2.4 V8 engine. For many years F1 cars all used a 2.4 liter V8 engine, but this year FIA said they should be more eco-friendly, they should protect the environment, save more fuels and help small scale teams to save their cost, so they decided to put a smaller engine into F1. I think they totally ruined this race with such kind of rules. This year F1 sounds like a normal sedan which its engine will blow itself up in any second. I thought everyone will have the same opinion with me about this issue. But surprisingly, there are some guys who think that this kind of quiet and horrible engine sound is brilliant! Sorry guys, I cannot agree with that.

Here is a brief  YouTube video which was made by a F1 audience.

He was on the almost same seat on the auditorium of race in 2013 and 2014 Melbourne Australia. You can hear the big difference of these two engines between the 2013 season and 2014 season. The 2013 engine sound is a high-pitch and high-frequency sound. But the 2014 engine sound is much lower and quieter. If you notice the faces of the audience in the video, you could see how the disappointed about this year’s race. Actually after the beginning of three races of 2014, almost everyone is complaining about the engine sound. Everyone said the sound is too low, it is not exciting, not F1 sound should be. But some guys say that they agree with the FIA, they think this sound is good. Because the low sound can protect the staff and drivers from damaging their audition. And also you can hear the tires scream when the car get into the corner, and the sound of the gear change, these sounds are also exciting. These reasons do not make sense to me.

Here are my points about the engine sound. First, the staff and the drivers all have the ear plugs to protect their audition. FIA will certainly put their health in front of everything. And on the early days of F1 like 1980s, the sounds were much bigger than today, but the drivers’ audition are still good when they get old. You could always see old F1 drivers like Niki Lauda appears in the pits and talks to other people with the huge engine sound on the track. They can prove there should be no worries about staff and drivers’ audition. Second, I think the engine sound is much more exciting than the sound of tires and gear changes. Now let the statistic speaks for me, this year the number of audience has reduced by more than10% so far than last year. In China F1 loses more than 30million audience this year. Please do not forget, this number is just in China, but what about other place in the world, there must be more loss. On some hot website like Top Gear, if someone mentions this year’s F1, almost everyone will express their disappoints with the engine sound. So it seems that most of the audience have the same opinion with me. If FIA does not fix the engine sound problem, they will no longer have any interests in F1, the decline of the audience number will cause serious job problems.

This map below shows all of the countries which will have F1 race this year.

You could see how popular F1 is all around the world. There are more than 2 billion people watch F1 every single race. Such big number of audience make F1 becomes a very profitable race. It provides a lot of relative jobs like engineers andtechnicians. F1 helps many people get a job to feed themselves or their families. If the number of audience decreases a lot, F1 may not able to continue, it will let a lot of people lose their jobs. The world economy has not fully recovered yet, it will be very hard for these people to find a new job. So FIA must do something to maintain the number of audience, they must enact new engine rules.

Actually FIA knows they have made a mistake, and they are trying to fix this problem. But their solution is based on they do not change the engine. Their preliminary idea is that they could put a kind of sound amplifier in the car, and make the engine sounds louder. I do not like this way, this is not the true sound of the engine. I think audience like hearing the natural sound of the engine, not the sound which be revised by FIA on purpose.

Here are my suggestions to change the engine sounds. I have come up with four ideas may could make the engine sounds better. First idea I came up is the most fundamental one: change the engine. I know it is impossible to change the engine this year, but FIA could change it next year or later. Because it is Formula One, FIA should not think too much about saving the fuel, they should think how to make the F1 cars faster and faster. Letting other race like 24 Le Mans to save fuel. Please do not misunderstand me, I am not saying we should not protect our environment. I am an environmentalist, I just think F1 should keep being what it should be. Actually I think F1 cannot save too much fuel per a year by using a V6 engine. So why do not let F1 use more fuels and bring us much more happiness. My second idea is FIA could put a butterfly valve in the F1, it is a small device which can make a huge change of the engine sound. You could even adjust its opening angle to let engine make a completely different sound. Nowadays a lot of sports car have a butterfly valve, so F1 also could put it into the car. My third idea is to rise the engine’s rotate speed, now the engine’s rotate speed is restricted. I recommend to remove this restriction, so the engine will achieve a higher rotate speed, and then comes the high-pitch and nicer sound. My last idea is that FIA could allow F1 teams make an engine with a bigger displacement, letting the engine be 2.4 liter, not just 1.6 liter. I think it may could have some changes on the sound.

Finally, I just want to say the engine sound is the essence of F1. In some small countries like Singapore or Monaco, every time when there was a F1 race, the whole country can heard the F1 was running. What a sound that is, I really hope I could hear such nice sound in F1 again. This is many people’s favorite sports event, please do not kill it.

Couple reasons why global warming is not due to human activities

By Chudan Wang

During the recent years we have heard a lot about global warming and how much it influenced our climate and daily life. Advertisements were shown everywhere that human activities are the reason why temperature keeps growing. In that case, people need to try to be environmental- friendly as much as possible and reduce the releasing of warm-house gases. However, according to some current  researches and videos about the real reasons about global warming, human activities are not the main reason of global warming, they are not enough to rise up the temperature of the whole globe. Recently, people can find resources about whether global warming is caused by man or not. Both sides have their “scientific evidence”. It is not quite easy for people to evaluate  the images and data on the internet. How credible or trustable the speakers are, different groups have different opinions. Although there are more texts that support that human activities are the causes of global warming, there are other voices arguing that global warming is actually not happening, it is natural, carbon dioxide can not be the cause of global warming, human activities produce much smaller amount of warm-house gases and here are some other links:

Dr Don Easterbrook Exposes Climate change Hoax

The IPCC Exposed

Great Global Warming 

The great global warming swindle

Firstly, scientists did a lot of research about The Vostok ice core sample. There are gases that remain in the ice which can help scientists to figure out the form of the atmosphere before. After research, scientists got the relationship between carbon dioxide and world temperature. They found out that temperature was increasing from 800 years ago, besides, CO2 is not the only gas that can heat the earth. Temperature doesn’t follow carbon dioxide, then who is controlling? Evidences showed that temperature is changing regularly, following the changes of the sun. Judging from the gram of global temperature dynamics through thousands of years on earth, there were much longer time periods when the globe was much hotter.

Secondly, even if CO2 is the reason if global warming (though it is not, supported by many scientists), what human is producing is just a small amount. Earth is a huge ball for human. There are a lot of elements that can release warm-housing gas. Oceans produce the most amounts of CO2 and water vapor. Besides, water vapor can cause more effect on global temperature. The second are the volcanos. Volcano activities can produce huge amount warm-house gases. Human- beings’ produced CO2 can not catch up with the “number” of other sources producing warm-house gases.  Animals and plants also produce a lot more CO2 and other gases. After the death of animals and plants, CO2 is produced along with decomposed by microbial. In those cases, Human does not response for producing too much warm-housing gases.

Thirdly, there are some political or economy reasons that people get the information about global warming caused by human. Governments want people to believe in this way for their own interests. Some big companies are earning a lot by “global warming”. Huge amount of jobs are related with this public belief. Everybody on the planet might be the stakeholder of this global warming controversy. Too much unknown and too much unbelievable facts. Detailed facts could be make people shocked and strong reflections. Countries are fighting with oil and sources for countries’ use. By sending the messages of human caused global warming  and may destroy the living circumstance of all lives on the earth and everybody on the planet is responsible and believed so. Effects of this public belief is very obvious.

It may not be easy to believe what had been known for decades, most of people had hold the idea that human causes global warming for a long time. Besides, among all kinds of media sources, the conditions of those debates can easily make people confused and hard to choose a “side”. The truth can not be always be hided, especially for such a big deal. More explains from the supporters of the two opposite opinions would gradually coming up and progressing, along with the dynamics of the public supports.

Moreover, here are some links for global warming is caused by human:

NASA

National Geographic News

people can also find many published books and articles with many explains of global warming. This issue appears on text books of all kinds of schools which seems strongly appeals to ethos.

It is good for everybody to take care of our living circumstance and be environmental friendly, such as recycling, reduce pollution from many perspectives, however, it is necessary for people to know what is really happening without getting true messages.

Here are some debates from the public about “Global warming”: (debate.org)

 

Opinions for global warming is caused by human: 

 

Global warming making a good point

 

“Becuz we have all this stuff we are putting in the air like the pic that is on this all the full from are cars all the littering we are throwing are trash on the ground and all that why when the end comes it is not going to be nothing we are going to make it happen before any thing else people do not think about this kind of stuff i hate people becuz of all that stuff just if you would stop all that bad stuff the world would be a lot better then it is right now all the war all the bad stuff we put in the air”

 

 

Opinions that humans are not the cause: 

 

Humans are not responsible for global warming.

” No, because compared to the size of the Earth, human activity is pathetically small. We don’t cause it. We do contribute to it. Global warming has been happening for a long time and it started before humans existed. Meaning that global warming happens from nature. Humans may have speed up the process a little bit but it is mainly nature and the outside environment. This planet has gone through many ice ages before humans were here. Global warming is probably happening, but I do not believe that it is the fault of humans. This planet has not had the same climate through it’s entire existence. It has warmed up and cooled down many different times and I think that we are in one of the warming cycles. Also I question the accuracy of the thermometers they used 100 years ago to even think that the entire world is warming up. Global warming is NOT humans fault and responsibility.”

It’s just apart of Nature.

 

” The world heats up every couple of centuries. It’s apart of how it works, to help renew itself. It replaces the old with the new. Human’s have made an impact, a small one… While this is the worst on record, so was the last one, and the one before that. It’s not because of humans.

As the populations of ALL animals increase, methane and Carbon Dioxide amounts increase. With this in mind, every time the world heats up, it get a little worse. The world will naturally cool down on it’s own, and life will carry on.

Scientists believe the world can hold hundreds of billions (exact amount is hard to pinpoint) of humans. We aren’t the problem, only a piece of it, not that there is a problem right now. When the “renewal” process the world goes through is down, we won’t notice it anymore.

It’ll be another 150 years before the world heats up again. It might take 300 years for it to be too bad to ignore, but it still won’t be all because of humans. In the end, it’s just apart of Nature.”

I think they totally ruined this race with such kind of rules. The car becomes slower, ugly and quiet. But actually I am fine with its speed, because the speed is not too slow, and it will reduce the potential danger for the driver. And I do not want to talk about how the car looks like, because it can be influenced by too many factors such as aerodynamic, safety reasons, costs and so on. So here I just want to talk about the engine issue, I have many to say about this.
