As our food supply has become more sophisticated, the number and different additives-the substances added to foods in processing either by accident or design-increased. There is a swirl of controversy around this topic, as food scientists and health professionals consider the negative aspects of to add items to our food, not as found naturally.
There are a number of reasons why food producers additives in their products. These include, in order to preserve food for a longer shelf life, improve color create texture, to improve the taste, to increase the nutritional value, to appeal to a niche market and make the food more economical.
There are two types of preservatives that are added to food to keep them from ruin. Anti-microbial substances such as sugar, salt and nitrates, inhibit the growth of these microbes that can cause food-borne diseases. Antioxidants protect the food from damage due to exposure to oxygen and includes sulfates, BHA and BHT are. Vitamin c and Vitamin E, anti-oxidant vitamins can also be used for this purpose.
Colors are added to food to give them more eye-appeal. Most of us expect packaged Macaroni and cheese be orange, colas be Brown, butter-like lookup must be yellow and raspberry gelatine must be red. None of these foods would have these colors without the presence of additives. In recent years been attention to find natural plant sources for these color additives, unlike their artificial cousins.
Texture of our food can be so important for us as color. For this reason we find emulsifiers and thickeners in many, if the foods that we enjoy. These substances to keep food from crystallizing, disassociate, or otherwise change to a form, which we could find unpleasant.
Is probably the most common type of food additive is used to enhance the taste of food. These additives can be natural-herbs, spices and fruit flavors or artificial variants that have been created in a laboratory. This category includes also artificial sweeteners, which has been the subject of much debate in the last 50 years. There is also a substance called MSG (mono-sodium glutamate) a commonly used flavor enhancer, has created a storm of controversy that still rages.
In order to increase the food which it produces nutrient value food producers will often add nutrients to their products. These include adding b vitamins and iron to cereals and grains, vitamins A and d to dairy products, Calcium and Vitamin C to fruit juices and even iodine table salt. These nutrients may be added to replace those lost during processing or improve the quality of a food that otherwise would not have this specific nutrient.
The addition of a specific substance to a food is sometimes purely a marketing decision. If a particular additive will help sell the product, than it is added to the feed. For example, Pomegranate juice be promoted as a super food, and as a result, it appears added to everything from Apple juice to cookies. In the same way we found Bran is added to many products, when fibre were new watchword nutrition community. Artificial sweeteners are often used to attract those watching their weight, or on a diabetic diet.
Save money on processing is probably the least attractive reason for why additives in food processing. It is called the bottom line. If a food business operator can use less expensive natural ingredients by adding taste and color marketing advantages, so that they do so. If a cheaper additive can be produced to replace a more expensive, most food companies will choose the cheaper version. An example of this kind of thinking is the ubiquitous presence of high fructose syrup-corn in the food supply, a cheap but controversial substitute for sugar cane or beet sugar.
The FDA has regulations on food additives, which are trying to assure that they are used safely. They try to keep the list of authorised additives that are safe, effective, and shown on the package. Unfortunately, there is a real question of what constitutes "safe", and this leads to a constant clamor from those who are in favour of a stricter standard of safety than the one currently in use. With the prevalence of cancer rising, there is a real concern over a possible link between certain additives and the disease.
Some additions could be called "accidental additives.
Not all foreign substances come into our foods by deliberate methods. Sometimes it is the method for the manufacture and processing of food, which introduces the substance and some times it is the form of packaging or storage. An example of this type of additive is dioxins in food packages that can contaminate food, especially if it is stored in a while. Hormones and antibiotics to animals, can find their way to the meat and dairy products we consume. These are "additives", which are not listed on the label, and yet can have an impact on their health.
An interesting example of this is when you see the warning on their labels that the product was manufactured with the help of equipment used to treat peanuts. This is because people who have a Pcen allergy can be so sensitive that even trace amounts can cause a severe allergic reaction. This is a case of an inadvertent use of the additive that can cause a serious problem.
Now that you know what you do
Now that you know about the types of additives, which can be displayed in your food, it is up to you to decide what, if anything, you want to do about it. At least you can learn to read labels, so you know which food additives are in the foods you eat. Another option is to choose more organic food, which is generally produced and packed with fewer additives, in particular those which can compromise your health.
Vote with your food dollars.
As food consumer, you can have an impact on the food supply. Each time you buy an item in a merchant at a farmers market, online or anywhere else, you cast a vote in favour of continuing the production and sale of the product. Conversely, each time you choose not to buy any food that is overly processed or adulterated in any way to make it less healthy we cast a vote to remove the product from the food supply.
