Food is filled with Natural chemical that are essential to our health, but some foods include potentially unsafe substance called natural toxins.
Most natural toxins happen naturally in just few foods and other natural toxins are produced when the food is damaged or when mould or fungi growth on the food,
First natural toxins produced by fungi: Example Mycotoxins.
Mycotoxins
The Mycotoxins are metabolites of mould which may infect foods, animal feeds and that happen to be toxic to human. The study of Mycotoxins, and the legislation associated with their control are based on them being considered as adulterant of foods and animal feeds.
Huge amounts of food are wasted every year due to which are attacked by toxic fungi or contaminated by fungal metabolic products. Such waste occurs most significantly in hotter countries where food shortages may already be a problem. One estimate (CAST, 2003) is that Mycotoxins affect a quarter of the world’s food crops, Including many basics food stuffs and animal feeds as well as crops. Mycotoxins are toxic chemical products formed by fungi that can grow on crops in the field or after harvest and the food that can be affected including cereals, nuts and dried fruits; coffee coco spices oilseeds and milk
Some of the Mycotoxins such as aflatoxins are among the most potent mutagenic and carcinogenic substances known (CAST, 2003). Mycotoxins are associated with many chronic health risks, including the induction of cancer , immune suppression, an digestive blood and nerve defects (CAST, 2003, Shepherd, 2006).Now there are more than 300 known Mycotoxins are found with widely different chemical structure and different mode of action and some target the kidney and liver and immune systems. Common Mycotoxins include aflatoxins, ochratoxins A, alkaloids, fumonisins and patulin
Mycotoxins are toxic secondary metabolites of fungi that are usually belongs to one of the three genus
1] Aspergillus Species, 2] Penicillium 3] Fusarium
Aspergillus Species:
Aflatoxins:
Aspergillus specious occurs in food as spoilage ago. They are very common in stored food products such as, Grain, nuts, and specious occur more frequently in tropical and subtropical then in moderate climates. Mycotoxins were brought to the attention of scientist in the yearly 1960s with the outbreak of turkey X disease which killed nearly 100,000 turkeys and other farm animals in England. The origin of the disease was traced from pea nut meal in the feed which was heavily contaminated with A. flavus. Analysis lately found that a group of fluorescent compound were responsible for the outbreak and named aflatoxins.
American society has grown so accustomed to receiving their food right away and in large quantities. Only in the past few decades has factory farming come into existence that has made consuming food a non guilt-free action. What originally was a hamburger with slaughtered cow meat is now slaughtered cow meat that’s filled with harmful chemicals. Not only that, the corn that that cow was fed with is also filled with chemicals to make them grow at a faster rate to get that hamburger on a dinner plate as quickly as possible. Bryan Walsh, a staff writer for Time Magazine specializing in environmental issues discusses in his article “America’s Food Crisis” how our food is not only bad for us but dangerous as well. The word dangerous could apply to many different things though. Our food is dangerous to the consumer, the workers and farmers, the animals and the environment. Walsh gives examples of each of these in his article that leads back to the main point of how dangerous the food we are consuming every day really is. He goes into detail on each of them but focuses his information on the consumer.
Botulism is a rare but very serious paralytic illness that is caused by the botulinum toxin that is produced by the bacterium Clostridium botulinum. C. botulinum is a gram positive, anaerobic, spore forming bacterium that is naturally occurring in soil. Botulism dates back to the eighteenth century when the first food borne botulism was documented. During this time many people were doing home fermented sausages and this was thought to be the cause of botulism. This is how the toxin got its name since “Botulism” in Latin comes from “botulus” which means sausage. E. van Ermengen was the first to discover the microbe in 1897 after there was a food borne outbreak in Ellezelles, Belgium. To date there are six forms of botulism but only two forms were known until the twentieth century which were food borne and wound botulism. The first type of botulism is food borne which is a result of ingesting food that contains the pre-form toxin. Some foods that this typically occurs in are home canned vegetables, cured pork and ham and smoked or raw fish. Wound botulism is the result of C. botulinum spores growing in a contaminated wound with in vivo production. Most people that get wound botulism usually have deep and contained avascular areas and many people also had compound fractures. Wound botulism is on the rise in the U.S. because of the use of illicit drugs, “the majority were linked to injectable drug use, particularly with so-called ‘black tar heroin’ and others with nasal or sinus lesions due to chronic cocaine sniffing.” (CDC website) Another form of botulism is infant botulism. This is caused from the endogenous production of toxin germinating spores of C. botulinum in the intestines of the infants. Also feeding an infant...
In a recent study, Nicholas P. Spanos and Jack Gottlieb were able to study biological occurrences that could account for the mysterious behavior of the young girls. The two studied ergot, which is a fungus that can infest rye and other cereal grains under specific conditions. The two discovered that when ingested, the ergotized grain may produce a remarkable amount of symptoms including, but not limited
Americans should eliminate their regular consumption of animal products and processed foods. This type of diet leads to preventable and expensive health issues such as heart disease, diabetes, obesity and even death. Most Americans don’t realize that the majority of the food being advertised to them is literal garbage that’s infusing their bodies with toxins on a daily basis. As Americans, we take pride and joy in our food, given the fact that it’s so darn tasty. We find comfort in eating a cheeseburger with French fries and slurping down a 44-ounce cola. However, what we eat has a far more detrimental effect on our health than most of us are aware of. To some, making the switch to a raw food diet might seem to be taking a drastic measure.
More precisely DON is classified as type-B trichothecene [20]. It is produced by Fusarium culmorum and F. graminearum [(Maresca, 2013). DON contamination is observed worldwide, within cereal crops such as wheat, maize or barley being most frequently affected (Richard, 2007). Furthermore, silage contamination is regularly observed (Tangni et al., 2013). Cold and wet weather conditions favour DON production (Lindblad et al., 2012) and it was found that the timing of the rainfall is more influential than the amount of precipitation (Mesterházy, 2002). In animal husbandry, DON, also known as vomitoxin, is primarily known for causing feed refusal and emesis in pigs (Pestka, 2007). This mycotoxin also alters the immune response and the intestinal functions (Pestka, 2007). DON may be produced together with two acetylated derivatives, 3-AcDON and 15-AcDON, that have differential toxicity on pig intestine (Behrens et al., 2015). Poultry are not as sensitive to DON and feed refusal is only observed at very high concentrations (16–20 mg/kg feed) (Whitlow and Hagler, 2002). Ruminants are the least sensitive animal species to DON, a fact that is attributed to the capacity of rumen microflora to detoxify this mycotoxin (Fink-Gremmels,
To help keep crops from being destroyed, conventional farmers use many methods such as pesticides, herbicides, and fungicides. Nearly 1 billion pounds of these chemicals are used every year (“pesticides”). Because of this excessive use, some scientists express concern that using artificial chemicals in the farming process could produce unhealthy crops. People who ate it over a long period of time could suffer from degraded health and stunted growth (“Organic Foods”). For example, in 1989, the EPA banned the use of Alar which was a chemical used to ripen apples (“Farming, Organics”). This chemical proved to be carcinogenic after causing tumors in mice after several laboratory tests (“Organic Food”). As a result of these findings there was a dramatic increase of the sales for organic food (“Organic Food”). Another study found that Atrazine (one of the most widely used herbicides in the United States) has the potential of being carcinogenic and reducing sperm counts in males (“Organic Food”). This was further proven when evidence was found that chemicals u...
In this exercise, Penicillium was utilized, a common, safe, mold. Certain species of Penicillium will spoil fruits, vegetables, grains, and grasses. Other species will ripen various chesses. Still, other species are used in the production of antibiotics. The species of Penicillium, italicum is provided for the lab because of its pronounced hyphae. Penicillium italicum, along with Penicillium digitatum attack citrus fruits post-harvest. In this experiment, the effect of Penicillium italicum on two types of citrus fruits and one non-citrus fruits were tested.
...niable, controllable connection between diet and cancer. To avoid increasing the odds of promoting all kinds of cancer, people should avoid animal products altogether and focus mainly on consuming vegetarian products in order to fully satisfy the requirements of the human body.
Not only is nonorganic food not as nutritious as organic food, even though they are made with hormones and special pesticides, it is due to the very hormones and pesticides they use to make them that some people can get sick and develop health issues like cancer. In an effort to make cows grow bigger and faster for a quicker rate of meat production, estrogen is given to them at an early age to quicken the process. However, as studies showed, when people consume such estrogen-infected meat, women in particular, showed signs of developing breast cancer. Not to mention the rapid increase in puberty of children who drink milk, which also has estrogen and testosterone hormones in it. In studies conducted, it was noticed that children who drink this milk, which contains these hormones, were going through puberty at a young age. This being another reason why ...
The advancement in chemical technology with these improved pesticides has created improvements in the public health as well. From this, perhaps, we have become careless in our use and control of them. While there are many positive points, there are also extreme risks involved in using th...
Being natural doesn’t mean that the product should be considered a safe product. These products are designed to affect the body and could cause side effects. Natural health
Food has been a common source of necessity in our everyday lives as humans. It helps gives us nutrition and energy to live throughout our life. Over several decades, the development of making foods has evolved. They have changed from natural to processed foods in recent years. Nowadays natural ingredients are barely used in the making of foods like bread, cheese, or yogurt. The food industry today has replaced natural food making with inorganic ingredients. The cause of this switch is due to processed foods being easier, cheaper and faster to make. Artificial nutrition and processed foods have been proven to last longer in market shelves then natural foods. Also, due to artificial additives in processed foods they help satisfy consumers taste more than natural ingredients. The method of producing processed foods is common in today's food industry and helps make money faster and efficiently for companies. Examples of this can be found in all markets that distribute food. Even though processed foods may be easier and faster to make, they are nowhere near as healthy for consumers compared to natural foods. Natural foods are healthier, wholesome, and beneficial to the human body and planet then processed foods.
CHEMICHALS: Scientist have defined hundreds of chemicals that can cause cancer in animals. These chemicals are also a cancer hazard for human beings if they become widespread in food supply, the general environment, or the living and working environment. In most cases, a chemical carcinogen enters the food supply as a food addi...
Food is “composed of synthetic chemical additives, such as colorings, preservatives, sugar substitutes and trans-fats” (Fitzgerald, 2006, p.72). Fitzgerald reported that by the “1970s most meats and dairy products that were factory farmed were laced with growth hormones, antibiotics and a range of pesticides” (p.72). Furthermore, food that is frozen, packaged and canned is considered processed food. A brief explanation of the chemical additives in processed food. 1.
Food safety is an increasingly important public health issue. Governments all over the world are intensifying their efforts to improve food safety. Food borne illnesses are diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food. “In industrialized countries, the percentage of people suffering from food borne diseases each year has been reported to be up to 30%. In the United States of America, for example, around 76 million cases of food borne diseases, resulting in 325,000 hospitalizations and 5,000 deaths, are estimated to occur each year.” (Geneva 2)
