Food Preservatives Can Be Harmful



Foods today have not undergone the natural food chain anymore, since people have changed them to produce more than less, to meet the demand of cheaper and more food. For instance, cows no longer eat green grass, their main and natural source of food. Instead, they eat corn, while the fishes eat poultry and chickens eat fish. When it comes to plants, fresh vegetables and fruits are usually exported while local markets also sell goods coming from other countries.

Food prices are rising, but in reality, people spend less on modern food than in ancient times, courtesy to the contemporary practice of food production. However, the price is perhaps greater than what is expected. This write up is not aimed to scare people and eradicate some modern foods which are mostly fast processed, from everyday diet, but to give knowledge of the ingredients people may not be aware of, and in a way, are depriving themselves of the fundamentals of nutrition.

Food processing and preservation

Food shelves today are mostly filled with fake foods, junk foods and processed foods, which are actually real food that undergo devitalizing chemical processing and are infused with preservatives. Canned foods, hot dogs, low-fat yogurt with artificial sweeteners are examples of these processed foods. Intake of these foods costs the body more to digest and eliminate, than offering nutrition. That is a poor return of investment while the body is left depleted and sluggish.

Ancient people used salt, sun drying and fermentation to naturally preserve foods. From this simple food preservation evolved more complicated methods, and today, food companies use thousands of chemicals and additives to process food, many of which can be devastating to the health. Many preservatives used today carry toxic chemicals that are more problematic to the health of humans, than the decay they aim to stop.

Furthermore, the good intentions of food processing during the early days have de-evolved to find ways of cheaper food processing to produce more and increase profits, while the health of the consumers is jeopardized.

Preservatives

Preservatives are additives that prevent the food from spoiling. Some examples are nitrates, nitrites, benzoic acid and sulfites like sulfur dioxide and metabisulfites.

Nitrites and nitrates are found to cause nausea, headaches and asthma in some people. These preservatives are found in meats like bacon and ham. Sodium nitrite in some foods is converted to nitrous acid when humans ingest it. Despite showing increased cancer rates in animal testing, it is still in use.


Margarines, carbonated beverages and fruit juices usually have benzoic acid or sodium benzoate, which can cause allergic reactions, and even death in some people.

Sulfites are used to stop fungal spoilage and browning of peeled vegetables and fruits, like apples, potatoes and dried fruits, to prevent brown spots. It is also applied to molasses. Along with the toxins it contains, it bleaches rotten foods and conceals inferior vegetables and fruits. They have similar effects as nitrites and nitrates, plus allergic reactions. Sulfites destroy vitamin B1, thus, it is not allowed to be used in foods with such vitamin. People who are sulfite-sensitive, respond to the foods containing them with adverse reactions. It is found to worsen asthma in humans and about 5 to 10 percent of chronic asthmatics are thought to result from sulfite sensitivity.

There is also the controversial butylated hydroxytoluene, one of the most common preservatives, which is permitted at a low level in foods. With butylated hydroxyanisole, it is investigated further for its ability to harm genetics. Research showed these compounds BHT and BHA can damage red blood cells and trigger chemical sensitivity.

 
While foods with preservatives cannot all be harmful, the addition of milk and vitamins to them, help cover up the adverse effects they can cause. If most people understand the consequences of preservatives, or how the food they eat is processed, they will be able to make wiser choices on how many of these foods they are willing to eat.
