What Are the Benefits of Addititives & Preservatives in Food?
Overview
When you hear the word "preservative," your mind probably conjures up an image of strange, harmful chemicals. In this case, the image doesn't fit the truth. Adding preservatives to food has many substantial benefits that just may save your life.
Savor the Flavor
Food preservatives have many effects on food. One is a more enhanced flavor overall. Many preservatives, such as benzoic acid and nitrates, keep fruits and vegetables fresh by warding off the ruination that often comes with time, according to doctors from the School of Bioscience at the University of Surrey. But, increasing taste is just one important aspect of preservatives.

Preservatives Preserve
Preservatives also keep you safer from food poisoning and disease. Without preservatives, restaurants and chefs would have to hope that the food was fresh enough to be served to customers when it arrived. Preservatives such as ascorbic acid and tocopherols prevent this from happening by increasing the longevity of food, according to the University of Surrey study.
Preservatives Prevent
If "preservative" sounds like a bad word to you, keep one word in mind to put things in perspective: cancer. Improperly maintained food is subject to the effects of a disease known as reactive oxygen species, or ROS. This disease can contribute to cancer and cardiovascular disease. Since it is a pathologically spread disease, it has the potential to affect many, many people at once. Food preservatives protect the food from ROS and thus protect you from disease.
Additives and Nutrients
The role of preservatives is to protect the food and enhance the flavor, but food additives have another job entirely: enhancing content. Take milk, for instance: it is beneficial to your body on its own, but it still lacks the nutritional content that humans need on a daily basis. For this reason, vitamins and minerals are added to it for nutritional enhancement. Like "preservative," the word "additive" doesn't have to be a bad word in every case. When anything is added to food, it is included in the package label, per stipulation of U.S. law.
Additives and Consistency
Imagine that you saw a batch of apples and each one of them looked different from the rest, but in an oddly shaped and almost malformed way. According to research from Dr. Paula J. Busse, additives help to maintain consistency by keeping apples and other foods from having radically different textures, shapes, and sizes. While not all additives are healthy, the FDA has placed more than 700 of them on its "generally recognized as safe," or GRAS, list.

...“Clear thinking requires peace of mind rather than intelligence.” ~Meredith Forder … When it comes to making the right choices in life, mere intelligence will not guarantee the best result. This fact is exemplified by the problems of obesity, anxiety, stress, addictions and depression among highly intelligent people. At Clear Thinking we believe that many of life’s problems can be solved by simply learning how to think clearly—how to keep your mind calm, focused and within your control. Critical thinking...the awakening of the intellect to the study of itself.  Critical thinking is a rich concept that has been developing throughout the past 2500 years.  The term "critical thinking" has its roots in the mid-late 20th century.  We offer here overlapping definitions, together which form a substantive, transdisciplinary conception of critical thinking. Critical Thinking as Defined by the National Council for Excellence in Critical Thinking, 1987 A statement by Michael Scriven & Richard Paul, presented at the 8th Annual International Conference on Critical Thinking and Education Reform, Summer 1987.  Critical thinking is the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.

...used, but few people know or realize that food could be just as damaging. Food is just like water, we need it to survive, but if it is used in excess it could be very damaging or deadly to the human body. America and the world have been getting larger and larger over the last thirty to forty years which has lead to health problems and will lead to decrease in life expectancy. So what has caused this shift from normal body fat to excess body fat? Many people believe that the increase in the world’s body fat is due to fast food and lack in exercise. Although these factors may be true there is more to that than one would think. Fast food and possessed foods are a main contributor to excess body fat as Andrew Martin writes in an article “Hardee’s restaurants recently scrapped almost its entire menu to focus on hefty sandwiches called Thickburgers--including the Double Bacon Cheese Thickburger, weighing in at two-thirds of a pound and 1,148 calories” (Martin, 2003, para. 1). This is just one example, of a burger that is more than half the recommended 2000 calories that a person should intake in a day. As “Georgia Guldan, a nutritionist and associate professor at Chinese University's biochemistry department, said: "In general [Hong Kong has] in the past 20 years or so, as have other places around the world with our global food system, gone from a more nutritious traditional wholefood diet to a less nutritious diet with more processed foods (Ho, 2007, para. 8).

Essence of Salt

...main reason for the addition of salt to food was for preservation. Because of the emergence of refrigeration and other methods of food preservation, the need for salt as a preservative has decreased, but sodium levels, especially in processed foods, remain high. The expected tastes and flavors associated to salt use is enormous coupled with the relative low cost of enhancing the palatability of processed foods, thus making it a key rationale for salt use in food preservation. However, taste is not the only reason for the continued use of high levels of salt in foods. For some foods, sodium still plays a role in reducing the growth of pathogens and organisms that spoil products and reduce their shelf life. In other applications, sodium levels remain high because salt plays additional functional roles, such as improving texture. A number of other sodium-containing compounds are also used for increasing the safety and shelf life of foods or creating physical properties. This work begins with a review of the non-taste or flavor-related roles of salt and other sodium-containing compounds in food. The second part will briefly discuss the role that sodium plays in various food categories and provides examples of the sodium content of various foods. ------------------------------------------------- FOOD SAFETY AND PRESERVATION ------------------------------------------------- As mentioned previously, the first major addition of salt to food was for taste and to prevent spoilage...

Fresh Foods Vsd. Canned Foods

...1. Fresh foods vs. Canned foods When it comes to eating, this is something that people every day. They decide on what they eat and how it will affect their body. The main part that I am trying to make is to compare the differences in eating fresh food or canned foods. There are three main differences in fresh food and canned foods. First of all, the way it taste, cost, and how healthy it is for them. Most fresh foods have a really good taste when they are seasoned right. They also have a nice crunch when cooked and keep all of their natural nutrients. Some fresh foods began to lose their vitamins when they are picked. How-ever, if you are picky for having no added preservatives, salt, sugar, or fats, then fresh food is the way to go. Next , about canned foods. Canned foods are food that is processed and then put into cans. They do not have a lot of flavor and taste because there are some other chemical products added to them. Canned food also loses some of its natural food nutrients when stored. They are also packed with preserves that give you the same taste for months after you buy them. Canned foods can last a lot longer than fresh foods and are stored in syrup to keep fresh. The benefit of buying canned foods is that they are easy to find. Health wise, fresh foods provide them with fiber, vitamins, and minerals that your body ...

Fast Food

...Why are so many Americans drawn to fast food? Do they realize what goes on behind the scenes? The fast food industry operates by assembly lines. This means cheap labor because the workers specialize in one skill and are classified as unskilled labor. So, our fast food is cheap and we eat it because it's cheap, it fills us up and we have more money in our pockets to spend on other things. But, is this the way it should be? Fast food is the food of choice for many people because engineers have skewed it to be cheap only to make healthy food become more expensive. In my opinion, organic foods are what we should be putting in our bodies. But the problem is these foods are very expensive. My solution is better regulation of the fast food industry with stricter laws for hiring and producing quality foods. Unfortunately, it's not just the fast food industry that is ruining Americans health. The meat industry needs better laws and regulations as well. The average person eats 200 lbs of meat per year but if they knew how the animals are treated and what they're being fed, I believe they would reconsider what they're eating. Chickens are being fed antibiotics to make them grow faster and fatter. The slaughtering conditions are many times horrendous with workers treating the animals with no respect and abusing the animals. The reasons for much of this mistreatment is due to the fact that the workers themselves were unhappy with the way they were being treated and would get...
