Eating Healthy food can help you lead a long healthy life. Eating junk foods will lead to you suffering poor health, chronic illnesses, holes in your teeth and even Cancer.
The choice is yours!
In this guide I will enlighten you about the common hazards in our food. Be careful, eat wisely and you will stay healthy. Like a car needs good fuel & additives to run well, so too our bodies' need the right foods to thrive, heal and maintain itself. Eating ecologically grown foods also called organic or biological foods is the best and safest for our health and our families.
Peter was an active, successful 40 year old executive, in a high pressure job. His meal times were irregular, he usually heated up his food in a microwave, and bought whatever food he could on the run. One morning while evacuating himself he discovered that there was blood in the toilet bowl. Panicking, he went to see his doctor, who after examining and investigating him delivered some grim news. Peter had Colon Cancer. Peter was operated for the cancer, the bleeding stopped but Peter found he was very tired. A few months later he was discovered to have Liver Cancer. Peter was given a few months to live.
Peter's cousin advised him to seek out other means of treatment. Peter saw an iridologist who advised him that his problems were due to microwave residues irritating his intestine & the build up of pesticides in the tissues of his body. Peter was placed on a detoxifying regime to remove the pesticides and microwave residues and he gradually recovered.
Food grown using crop rotation to enrich the soil, using natural fertilizers like cow dung, leaves or compost, without pesticides or using natural pesticides like neem oil or tobacco is called organically grown food. Organically grown food does not irritate our bodies, often has much better flavour and can actively promote good health. A perfect looking vegetable or fruit, may be the result of too much pesticide being used, during its growth, transportation and storage. It is wiser whenever possible, to eat organically grown food, thus preventing cancer, allergies and auto-immune disorders.
Foods grown in far away countries, and not native to the country in which you live are more likely to contain preservatives and pesticides to enable them to be transported to your country. Similarly fruit and vegetables available out of season, are likely to have been preserved, often with the most economical but not necessarily the safest method. One way to identify organically grown vegetables or fruit is to see whether it shows signs of being decayed or eaten by insects. If it is safe for an insect to eat, it is likely to be safe for you to eat it too.
Present day techniques of growing food use chemical fertilizers, pesticides, insecticides, fungicides, and genetically modified seeds to maximize the crop yield. The biotech industry is fond of saying that they offer genetically modified (GM) crops that resist pests. This might conjure up the image of insects staying away from GM crop fields. But "resisting pests" is just a euphemism for contains its own built-in pesticide. When bugs take a bite of the GM plant, the toxin splits open their stomach and kills them.
The seeds of these plants are also sterile. http://www.seedsofdeception.com/utility/showArticle/?objectID=1264
Eating food grown with the help of these methods greatly increases your risk of getting indigestion, food allergies and diseases like asthma, migraine, auto immune diseases, obesity, heart disease and cancer. This little movie sums up this message nicely www.storewars.org.
Pesticides are substances used to poison and kill insects or other small animals. Insecticides are poisons used to kill insects. These are usually sprayed on plants, both while they are growing and on fruit, vegetable and grain to prevent them from being eaten. These poisons also affect and poison our bodies when we eat food sprayed with pesticides. Unfortunately many of us are blind to this obvious fact.
Spraying and using pesticides in our homes, offices & gardens also carries a high risk of giving us pesticide poisoning. I have seen several cases of breast cancer following the spraying of pesticides in homes and gardens to kill pests like cockroaches. Neem based pesticides are a better and safer alternative. Some pesticides are similiar to estrogens and mimic their effects on the body causing breast, ovarian and prostate cancer. Detoxification of the body to remove the pesticide has allowed the body to heal and destroy the tumour.
Pesticides persist in the soil and in our bodies for many years. They attach themselves to protein molecules and are a significant cause of food allergies as well as cancer. The great increase in food allergies seen in the last half of the 20th century is largely due to the widespread use of pesticides. Pesticides attach themselves to many of the enzymes which carry out vital functions in our body including mitochondria and lead to a loss of energy and efficiency. Pesticide poisoning is a significant cause of chronic fatigue syndrome, candidiasis and cancer.
Pesticides are also called POP's or Persistent organic pollutants. Some commonly used pesticides, commonly called the dirty dozen are DDT, lindane, aldrin, dieldrin, endrin, chlordane, heptachlor, mirex, toxaphene, hexa chlorobenzene, poly chlorinated biphenyles, dioxins and furanes.
These pesticides poison the soil and water for many years and enter our food chain through fruits, vegetables and grains as well as through meats and fish. These pesticides have a half life of between 40-150 years and hence will persist to even poison our great grand children. This is why most of the world's population have pesticide levels in their bodies which are 20-1000 times more than what the World health organization considers to be safe. As a result the incidence of Cancer, allergies and auto immune diseases has sky rocketed world wide.
Fertilizers are artificial nutrients added to the soil to increase the yield of food. If applied carefully in the correct dosage they have few adverse effects on health but if applied indiscriminately in the wrong doses they affect the soil, the water, our health and our bodies. Compost & cow dung are two commonly used fertilizers which are safe and organic.
All fruits and vegetables should be thoroughly washed in running water before eating or cooking. Raw vegetables and fruit can cause parasitic infections if not properly washed. Hydrogen Peroxide is a safe disinfectant which destroys bacteria & viruses with great efficacy and does not leave any toxic residues or bad taste. Soap or detergents should never be used to wash vegetables or fruit. Potatoes, carrots and other vegetables grown under the ground can be scrubbed clean with a brush. Cut away any damaged, over ripe or bruised areas in fruits and vegetables as bacteria thrive in such places.
Vegetables, fruits and grain which are eaten without removing the skin, should first be washed in a solution containing a tablespoon of vinegar and 2 table spoons of hydrogen peroxide in a litre of water. Vinegar can remove some pesticides present on the surface of fruits and vegetables. It does not however remove the pesticides inside fruit and vegetables. Apples & table grapes are two fruits which are often dipped in pesticide after harvesting to preserve them. Such fruit are best avoided or if eaten should be peeled before eating.
Monosodium glutamate (MSG), also called hydrolysed vegetable protein, ajinomoto, natural meat tenderizer etc. MSG is a common ingredient in fast foods, chinese foods, canned food, frozen food, prepared meals, sauces, salad dressing, cheeses chips and a multitude of other foods. It is an addictive substance associated with increasing appetite by stimulating insulin production, thus causing obesity, and diabetes mellitus. It is also a common trigger for headaches, migraine and elevated blood pressure. Consumption of MSG has a strong ling with stomach and colon cancer.
Artificial colourings, flavourings and preservatives used in processed foods cause irritation of the intestines, and can cause obesity, cancer of the liver, stomach, lymphatic system and intestines. Preservatives are poisons which are added to food to stop bacteria from growing on the food. Research shows that most preservatives used in foods are dangerous and suppress the bodies immunity and predispose to the development of cancer. They also poison the mitochondria and enzymes in the body leading to fatigue and loss of energy. People who eat a lot of food with preservatives are prone to chronic fatigue syndrome, candidiasis and cancer. Eating food made from fresh ingredients will help you live a long and healthy life.
If you are going to eat canned food ensure that the can is a steel can (commonly coated with tin and called a tin can) which should be free of dents, cracks and bulges. Once a can of food is opened it should be eaten immediately. If it has to be stored, transfer it to a sterile container and refrigerate. Canned foods are usually acidic in nature. Preserved food should always be consumed before the expiry date. If food sprays out of a can on opening it, do not eat it, as it is probably decayed and poisonous. Throw it away ! Many canned foods contain MSG.
Irradiated Food. Food is often treated with radiation to reduce the number of bacteria, and to kill the growing part of the food so it does not germinate or sprout. This helps to prolong its shelf life. However irradiation (treating with radiation) also destroys vitamins and other nutrients in the food and creates URPs (unique radiolytic products) some of which are carcinogenic (cause cancer). Foods which are commonly irradiated are wheat, flour, potatoes, red meats, poultry, pork, apples, eggs, spices and vegetables. In some countries irradiated food is labelled but in many countries, such labelling is not mandatory.
Dangers of eating meat grown using hormones. The association of hormones used in foods, with cancer and hormonal imbalances is very well known, yet poorly understood by most people. Cattle, poultry, pigs, turkey, eggs, salmon, eel, carp and other animals raised for use as food, are often given hormones to increase their rate of growth and to promote rapid weight gain. Hormones are commonly used to promote quick weight gain in chicken, turkey, quail, pork, beef, salmon and other meats. They are also used to stimulate production of eggs and to increase the yield of milk. Drinking large amounts of milk on a regular basis contributes to weight gain & obesity.
A chicken which usually takes 9-12 months to grow to a weight of 1 kg when left to roam freely in a garden, can be forced to reach a weight of 1 kg in 42-47 days with the use of hormones, (with newer hormones, in 17-20 days from the day the chicken hatches from the egg). The hormones and the lack of activity (the chicken stays in a tiny cage for all of it's short life) result in a chicken with a high fat content and soft tender meat. Animals grown in this unnatural way, also have a high content of fat and hormones, which, when eaten by you lead to weight gain, obesity, hormonal problems and an increase in cholesterol which in turn can cause heart disease. This is a leading cause for obesity and the increase in height and weight in the American population.
Hormone residues in meats significantly increase the risk of getting cancer of the breast, thyroid, vagina, uterus and prostate. It also causes hormonal imbalances including menstrual irregularities, weight gain and hair growth in ladies. In men it can cause impotence, a feminine voice, enlargement of the breasts, hypertension, prostate cancer, weight gain and obesity. An excellent book which describes in detail how cattle are cultivated for meat, and the health problems which affect those people who work in this horrendous industry is titled "My year of Meat" by Ruth Ozeki. Hormones, pesticides and some antibiotics accumulate in the liver, kidneys, skin and fat, so eating these parts are more likely to cause problems. Eating chicken liver pate (paste), liver sausages and other preparations from liver are often a sure recipe for disaster.
Animals raised in closed and confined spaces like poultry (chicken, turkey etc.), salmon & cattle, are routinely administered antibiotics to prevent infection. These antibiotics pass into their eggs, milk and remain in their meat. When we eat these eggs, meat or drink milk from these animals we also absorb these antibiotics. These antibiotics kill some bacteria in the body, and thus alter the bacterial distribution in our intestines, mouth, skin & genital tract making the body more susceptible to candidiasis. This is a fungal infection which flourishes in the absence of the normal friendly bacteria which normally live in these areas.
Antibiotics kill the friendly bacteria in the intestine which produce vitamin B, so eating food containing antibiotics leads a deficiency of Vitamin B. This problem can manifest as Chronic Fatigue Syndrome which responds well to a vegetarian diet, vitamin B supplements and replacement of the bacteria by administering acidophilus & lactobacillus. Some common symptoms associated with candidiasis & antibiotic use are flatulence, indigestion, fatigue, insomnia, loss of appetite, a white membrane with ulcers in the mouth, tiredness, vaginal discharge, diarrhoea, constipation, and skin infections.
Low level ingestion of antibiotics through meats, over a prolonged period, causes the bacteria which live in the body to become immune to those antibiotics. Hence when our immune system is suppressed by factors like lack of sleep, stress, malnutrition due to a deficiency of vitamin B complex or zinc, we fall prey to infections from these bacteria, to which the body is normally resistant. At this time, primary antibiotics are usually unable to cure these infections and the physician is forced to prescribe more toxic and expensive antibiotics. To safely eat eggs, meat or drink milk it is wise to eat eggs from free range chickens, to eat free range or organic meats and to drink organic milk and milk products.
Preserved and packaged meats like sausages, hams, bacon etc. usually contain Sodium nitrite, to preserve the colour of the meat & stop it from putrefying and turning gray. This is usually mentioned on the label and in the body is converted into substances called nitrosamines which are highly carcinogenic and lead to leukaemia in children, colon and pancreatic cancer. When you take sodium nitrite in the food you get a characteristic smell in the urine of the nitrosamines.
Shellfish like shrimp, prawns, crabs, clams, lobsters, oysters, mussels etc. live on the shallow sea bed and act as scavengers for the waste products which pour into the sea from rivers and industries. They selectively take up heavy metal residues, mostly mercury, but also nickel, zinc, cadmium and lead. Shellfish specially oysters are rich in zinc and cholesterol. Zinc helps boost the immune system, increase libido & performance. However the high cholesterol content, predisposes to arteriosclerosis and cardiovascular disease. Eating shellfish caught in waters near industrialized areas often causes food poisoning and allergic reactions.
Eating shellfish and fish contaminated with mercury can cause mental disorders (like the well described mad hatter in Lewis Carrol's classic book "Alice in Wonderland"). Hatters in the late 19th century used mercuric chloride to stiffen hat bands and in the process absorbed mercury. This lead to mercury poisoning which often manifested as mental disease. Mercury poisoning either from food or from improperly made amalgam (solution of silver in mercury) used to fill cavities in teeth can also cause neurological illnesses like multiple sclerosis, chronic fatigue syndrome, depression and loss of vision. Dentists, workers in gold mining, in paper and pesticide industries are some occupations specially to prone to mercury poisoning and as a result to mental illness and neurological illnesses like multiple sclerosis and loss of vision.
The famous outbreak of Minimata disease in Japan, where hundreds of people went blind & suffered other neurological problems, was the result of the fisher folk eating fish contaminated with mercury. Similarly mercury poisoning can cause Vitiligo, headaches, depression, eczema, chronic fatigue, and hair loss as the sulphur in the hair binds the mercury. Hair loss is often an early sign of heavy metal poisoning.
Large fish, high up in the food chain like tuna, swordfish, marlin, shark, king fish (serum), barracuda, etc. eat smaller fish and concentrate heavy metals in their bodies. These fish, specially those caught in coastal waters near industrialized countries can contain significant amounts of mercury, lead, cadmium and other heavy metals. Such fish are best avoided. Small fish like sardines, mackerel, herring, anchovies etc. which live in shoals in open seas are safer to eat. They are also rich in Omega 3 oils which help prevent, and reverse heart and vascular disease.
Fish eating birds like ducks also concentrate mercury in their bodies and should be avoided. Due to large scale use of mercury based pesticides in Africa & the USA (now banned), fish caught in the Atlantic ocean & along the Pacific coast of America usually contains dangerous levels of heavy metals as well as Polychlorinated Biphenyls (PCB's) which are very well known to cause cancer & are now banned for use in the US but not for export to other countries. The infamous Kennedy Hatch bill allows US based companies to export to other countries those substances which are nor permitted in the US. As we live in one ecosystem on this earth these poisons are now returning to haunt North America & Europe with a sky rocketing incidence of cancer. My recommendation is to not to eat fish caught in these waters.
Eating garlic, coriander (Cilantro) & foods rich in vitamin C can help remove mercury from the body. Mercuric salts are also widely used to fumigate grain, to kill pests, and mercuric tablets are often scattered in grain like wheat & rice to prevent infestations with pests. If these tablets are not carefully removed prior to grinding the grain they can cause mercury poisoning.
Mercury can be released into the environment from power plants which burn coal, paper & pulp making plants, gold extraction & refining plants, vaccine and other pharmaceutical industries, municipal waste facilities and medical incinerators. Mercury poisoning is also associated with mental disease, multiple sclerosis, autism, accelerated heart disease and reduced immunity. Vaccinations with vaccines using thiomersol to inactivate the vaccine have been implicated in autism in children and should be used with caution.
Heavy metal poisoning is also associated with endothelial damage and accelerated early atherosclerosis leading to ischemic heart disease and vascular disease. Most cigarettes contain significant amounts of cadmium (about 1 microgram each) and hence predispose to atherosclerosis. Lead is released into the environment from automobile pollution both from leaded petrol and from the wear and tear on automobile tires.

Hazards of Plastic & of Cooking food in microwave ovens. Cooking food in microwave ovens, alters food by causing cross linkages between protein and carbohydrate molecules to form synthetic glycoproteins. In a significant percentage (about 30%) of people, the body is unable to break down these synthetic glycoproteins. These glycoproteins can accumulate on the absorbing surface of the intestine forming an impermeable plastic-like layer. This layer can interfere with the absorption of carbohydrate and water soluble vitamins like Vitamin B & C leading to indigestion, malabsorption, irritable bowels, malnutrition and fatigue.
A similar layer of plastic can be formed in the intestine by eating food, or drinking milk & water packed in plastic bags or bottles which are not food grade. This indigestible plastic-like residue irritates the intestine and predisposes to colon cancer, anaemia and shortage of fat soluble vitamins.
Fats can be absorbed through this layer so the person develops a craving for fatty foods resulting in weight gain and obesity. This layer can be removed by eating foods rich in fibre like raw vegetables, fruit, bran, beans or psyllium husk.
Microwave radiation also converts amino acids into forms not found in nature and some of these are carcinogenic.
Microwaving food in plastic containers releases cancer causing substances called dioxins which often cause breast cancer. Instant noodles, soups, foods covered with cling wrap all release dioxin when heated in a microwave oven. If the foods contain fat the dioxin is absorbed by the fat and easily absorbed in the body as dioxins are fat soluble.
Bottled Water. Bottled water sold in PET bottles is generally assumed to be safer than drinking water straight from the tap. Some research has shown that water kept in PET bottles acquires antimony from the bottles. Antimony is used in the manufacture of the PET. To avoid this hazard buy fresh bottled water with a manufacturing date as close as possible to the current date. This contamination with antimony increases with the length of storage and is usually significant when bottled water is stored for 3 months or more. Antimony can cause depression and a feeling of being ill.
Reusing your disposable mineral water or cola bottles, (PET bottles meant for single use) can also be dangerous. Reusing these bottles is not a good idea as the plastic (called poly ethylene tetraphthalate or PET) used to make these bottles may contain a potentially carcinogenic substance called di-ethyl hydroxyl amine or DEHA. These bottles are designed for one-time use. They should not be repeatedly reused for more than a few days and should be kept away from heat. Repeated washing, rinsing and deformation of the bottle can cause the plastic to break down and the carcinogens (cancer-causing chemical agents) can contaminate the water that YOU are drinking. It is healthier to invest in water bottles that are really meant for multiple use, like poly carbonate bottles or use glass bottles. Pet bottles should also not be frozen as freezing the bottles releases dioxins which are cancer causing.
Similarly the plasticizer used in Cling wrap film is carcinogenic. Hence cling wrap film should never be used in direct contact with food. The use of this film to wrap sandwiches, cut fruit and vegetables is a bad idea. If it is to be used put the food in a glass container and wrap it with the film in a way that there is no possibility for the food to touch the film.
The great increase of colon and other cancers in "developed countries" is directly related to the increasing use of plastic, carcinogenic substances like pesticides, preservatives, colourings & microwave ovens. Fifty years ago colon cancer in the US was 0.5% of all cancers. Today it is estimated that one in twenty Americans will get colon cancer. The increasing consumption of highly processed foods, and the lack of fibre in western diets with more consumption of junk foods has contributed to this trend. Eating organically grown foods and eating more raw or semi cooked vegetables and fruit will help reduce the risk of colon cancer.
Artificial sweeteners: Saccharine, aspartame (brand names are Sweet & low, nutrasweet, equal etc.), Sucralose, (splenda) are all substitutes for sugar with more side effects on health than natural sugars. Saccharine is associated with a significantly greater risk of liver and bladder cancer. Aspartame use can cause neurological ailments, multiple sclerosis, muscle spasms insomnia etc. Aspartame is the sweetener commonly used in diet cokes and other diet drinks.
You are wise to avoid them and sick to natural sugars in small to moderate quantities (less than 45 grams (3 tablespoons full) per day in divided quantities) except if you have diabetes when you should avoid them totally. Stevia is a natural sugar substitute with some what greater safety than the artificial sweeteners.
Soft drinks contain many harmful substances, which when taken in excess, cause health problems described below. These substances include phosphoric & citric acids which attack your teeth and bones removing the calcium and causing osteoporosis. They also contain Caffeine which makes children and adults more excitable and hyperactive and make it harder to sleep leading to insomnia. Diet soft drinks, use aspartame as a sweetener, with all the side effects described above. In fact a BBC article recently described the use of Colas as pesticides. If it can kill pests surely it can kill you too!
Cooked food should be eaten fresh as it ferments with growth of bacteria when kept for any length of time. Cooked food provides an ideal environment for the growth of bacteria and so, should be eaten, as soon as possible after preparation. Cooking food, makes it easier to digest, and kills viruses and bacteria in the food. It also destroys the natural protective enzymes called lysozymes which are present in raw food and help prevent bacterial growth. Left over food, stale food and any food eaten many hours after cooking can cause indigestion and flatulence as bacteria, viruses and funguses like yeast are able to grow and multiply in this food.
Refrigerating foods reduces bacterial growth by lowering the temperature of the foods. Unfortunately most refrigerators are designed in a vertical format which allows the cold air to flow out of the bottom, when the refrigerator is opened and thus raise the temperature of the food as hot air flows in to replace this cold air. In households where refrigerators are opened frequently, the temperature of the food fluctuates, leading to bacterial growth and consequent deterioration in the flavour and quality. You should periodically check the temperature in your refrigerator which should be at 4 degrees Centigrade when you open it and at -10 to -15 degrees Centigrade in the freezer.
Frequent use refrigerators and freezers should be the horizontal chest type which open from the top, where the cold air does not flow out on opening the refrigerator or freezer. In large households or institutions several small refrigerators are a better idea than one large refrigerator, as it allows better maintenance of food temperatures. Food should be placed in a refrigerator so there is place for the air to circulate and cool the food. Foods for long term storage should be stored in the freezer or in the lower part of the refrigerator as these are cooler. The longer the food stays in the refrigerator the greater the chance of bacterial decomposition of the food. Food kept in the refrigerator tends to get dehydrated, with a change in taste and flavour unless stored in airtight containers.
Freezing foods destroys the cellular structure of the food due to the formation of ice crystals and leads to change in the flavour of the food. Food frozen quickly has less cellular damage, as the size of the ice crystals which form are smaller. If food is to be frozen it should be frozen quickly in sterile, small sized shallow containers immediately after cooking which enables you to defrost only what you need for one meal. Food for freezing should be frozen flat so it freezes quickly preventing bacterial growth and also defrosts quickly. To eat frozen food, slowly defrost it in the refrigerator for a few hours to minimize cellular damage. Repeated defrosting & freezing of foods should not be done as it leads to deterioration in the quality and flavour of the food and promotes bacterial decomposition.
Foods like unprocessed honey, turmeric, raw onions, and garlic have natural antibiotic qualities to prevent infection, and should be taken with food. In many places like North India, Turkey & Mexico, food is classically served with raw onions (a natural antibiotic to prevent infection) which is avoided by Westerners who are afraid to eat raw vegetables. Raw vegetables are often safer to eat, because they contain lysozymes which are natural antibacterial substances which reduce bacterial growth. In warm European countries like Italy, garlic is an integral part of the food for the same reason. Turmeric is used in most Indian cooking to prevent bacterial decomposition.
Freshly cooked food is both healthier and tastier than food which has been prepared, kept & reheated. To maintain your health always insist on having freshly cooked food. In the West eating freshly made food is a Luxury. For those of us who are able to afford it fresh food is a luxury which does not require wealth, but time, love and care which reflects in better health. In so called undeveloped countries where food refrigeration and other means of preservation are not available, many more people are able to enjoy the simple pleasure of freshly cooked food which is often a hard to attain luxury, in more developed countries.
Eating food which has been cooked and kept, leads to the common symptom of diarrhoea and flatulence which often afflicts travellers to the tropics. Cooked food kept at tropical temperatures allows bacterial growth, which occurs more readily in liquid foods than in solid foods. Decomposition is slower in foods which are deep fried in oil, than in foods cooked in water. Eating food in restaurants which are pre cooked and kept often leads to indigestion. In Chinese restaurants in the west this is often the case where food is displayed in show cases for you to choose.
Fat and Cooking Oils Fat should constitute 10-20% of your daily calorie intake. If you are physically active and live in cold climate your fat intake should be higher. In warm climates and with a sedentary lifestyle you need less fat in your diet. Your daily requirements thus range between 15 -60 grams a day of fat in your diet. (1-4 tablespoons). The body needs a mix of different types of oils for it to function adequately. This should be a mix of saturated oils like coconut oil, mono and di unsaturated oils like olive oil, peanut oil, mustard oil, sesame oil and polyunsaturated oils like safflower or sunflower oil. Eating only a single type of oil can lead to abnormalities in the levels of different blood fats in the blood.
Unrefined cooking oils are safer for health and should be used in preference to refined cooking oils. However unrefined oils and food cooked in them, tend to go rancid (decompose) faster when stored. Rancid oils have a stale soapy smell. If the oil is rancid return it to the shop from which you bought it or throw it away. Buy oils as close to the date of manufacture as possible and store in a tin or a cool dark place. Consuming rancid oil leads to increased free radical production which causes heart disease and cancer. If any oil or fried food is not being used immediately it should be stored in the refrigerator. Most vegetable oils (both refined and unrefined) decompose in four to eight months at room temperature. Common unrefined oils available are corn, olive, coconut, ground nut (peanut), sesame and safflower.
Refined oils are unbalanced oils purified by removing lecithin (which makes it easier to digest absorb & utilize fats), antioxidants like vitamin E & beta carotene (which prevent cancer), phytosterols (which protect the immune system, heart and arteries) and chlorophyll (which contains magnesium necessary for heart, muscle & nerve function). The refining process uses corrosive bases, bleaching acids and clays which may leave residues in the oil. Hydrogenated oils like margarine and dalda (commonly used in India as a substitute for ghee) should be used sparingly as they contribute to raising blood cholesterol when used in large quantities.
Oils made from nuts decompose faster than other oils. However, they can be used a few times for deep frying. Poly unsaturated oils like sunflower, safflower and corn should not be reused for frying. Saturated oils like ghee, coconut oil, animal tallow and palm oil, may be reused a few times for frying. Frying food specially potatoes & reusing the oil leads to formation of acrylamides (a cancer causing substance) in the oil and also in the fried food. High oliec sunflower oil, peanut oil, sesame oil, canola oil and olive oil (in that order) decompose less during cooking. Animal fat like tallow often contains large amounts of pesticides. Cotton seed oil(Bt) and soya bean oil from Genetically modified seeds contain modified pesticides are associated with increased incidence of allergies and cancer and are best avoided.
Food cooked in aluminium vessels or in aluminium foil can absorb aluminium because aluminium dissolves into food and water during the cooking process. This absorbed aluminium goes into the bloodstream and accumulates in different organs in different people causing a multitude of effects. Some unpleasant effects of eating food cooked in aluminium are hyperacidity, indigestion, flatulence, skin problems like pigmentation, eczema, dandruff and chronic inflammation of the intestine, which may be diagnosed or mis-diagnosed as Ulcerative colitis, Crohn's disease or as chronic amoebic dysentery. Aluminium reduces growth of bone and predisposes to osteoporosis.
Most non stick cook ware is made from aluminium or its alloys covered with a Teflon coating to prevent aluminium from dissolving in the food. Over time, this coating gets scratched and the aluminium is able to come into contact with the food and dissolve into your food. If you are using non stick cook ware they should be washed with soft soap and a soft sponge. Abrasive scourers should never be used to clean Teflon coated vessels. Scratching can be prevented by using plastic or wooden spoons to stir food in nonstick utensils. These spoons unfortunately also constitute a health hazard as bacteria thrive in the pores on the wood & plastic spoons which can rarely be properly cleaned. They should be sterilized frequently with a solution of bleaching powder in water. In view of this my recommendation for good health & hygiene is to use Stainless steel or cast iron cookware & spoons.
Recent evidence shows that the use of Teflon coated non stick utensils suppresses immunity and increases the risk of cancers of the blood like leukaemia especially in children. Dupont, the worlds largest manufacturer of teflon and non stick vessels is presently facing law suits from people who have developed cancer and have quoted studies showing that teflon does indeed poison the immune system.
Drinking water in some cities may contain significant quantities of aluminium as Alum is used in the water purification process to precipitate suspended impurities. A report of the aluminium content of the water is usually available at your water supply authority and is worth asking for. Aluminium is also often present in dental fillings, so when you see your dentist ask him to use non aluminium containing composite or glass polymer fillings.
Other sources of aluminium poisoning may be drinks (like colas & beer) in aluminium cans, draft beer packaged in aluminium kegs, foods packed in aluminium cans (sardines, tuna, soups, baked beans etc.); toothpaste, mayonnaise, mustard & sauces packed in aluminium tubes; poor quality tetra packs, pre-cut vegetables & chips and other snacks packed in Aluminium foil bags; processed cheese slices, deodorants, lipstick, water filters, free flowing salt where aluminium salts are added as an anti-caking agent, some baking powder brands and food cooked in aluminium foil. Baby foods & infant formulas often contain significant amounts of aluminium.
Aluminium dissolves faster into acidic foods than into basic foods. It is always unwise to cook acidic foods like tomatoes, tea & coffee in aluminium vessels. Some people with aluminium allergy may react to medicines packed in aluminium foil especially to acidic medication like aspirin. Many antacids contain aluminium hydroxide and should be substituted by calcium carbonate antacids.
Aluminium is also known to affect the brain causing dementia and Alzheimer's disease. The first signs of its toxic effects on the brain, is loss of short term memory. Continued exposure to aluminium over thirty to forty years may cause Alzheimer's disease. In Alzheimer's disease the patient is unable to recollect recent events, but is able to clearly recollect events which occurred many years earlier. At present there is no effective treatment for this.
It is often claimed that aluminium does not dissolve in the food. This can be disproved by taking some water and boiling it for half an hour in an aluminium vessel. Pour the water into a transparent glass and allow it to stand for a day. You will find a cloudy substance has appeared in the water, which is aluminium hydroxide. Aluminium utensils often show pitting where the aluminium has dissolved away.
Drinking freshly squeezed orange, pineapple, grapefruit or sweet lime juice can help remove aluminium from the body and help mitigate these problems.
This web site of the US agency for toxic substances and disease registry has more information on aluminium & its toxicity. www.atsdr.cdc.gov/toxprofiles/phs22.html,
The Canadian government has a similar site http://www.agr.gc.ca/pfra/water/alhealthe.htm.
