Mycotoxins are secondary metabolites produced by several fungal species and molds. The most common commercial mushroom, Agaricus bisporus, causes cancer in mice [Toth 1986]. That nutritional benefits from foods, whether raw or cooked, unavoidably come at the expense of costs and tradeoffs is a central issue that we will return to more than once, in different forms, as this paper proceeds. 1979, Kummerow 1993, Kubow 1993, O'Keefe et al. Thus if cholesterol and/or oxidized cholesterol are in fact atherosclerotic in effect, then the implication is that there must be something else in the diets/lifestyles of hunter-gatherer groups mitigating or negating this effect. (Lesson of the Pottenger's Cats Experiment: Cats Are Not Humans) Some flavonoids protect against the mutagenic effect of other substances. These contain toxic psoralens, which are potent light-activated carcinogens and mutagens not destroyed by cooking [Ivie 1981]. Lack of food diversity , lack of regulations. [C]onsumption of moderate quantities of this vegetable by man can result in the intake of appreciable amounts of psoralens. These contain toxic psoralens, which are potent light-activated carcinogens and mutagens not destroyed by cooking [Ivie 1981]. Of particular note here is the example of hunter-gatherer societies, where the incidence of heart disease is extremely low (perhaps the lowest that has been seen among human groups), despite the fact that relatively large amounts of cooked meat are consumed. GO TO PART 1 - Is Cooked Food "Toxic"? The basic characteristic of flavonoids is that their chemical structure includes what is known as the flavonoid skeleton, that is, a skeleton (core) of diphenylpyrans, i.e., C6-C3-C6, where the C stands for carbon, and C6 is a benzene ring [Hertog and Katan 1998]. It is also worth remarking that many other factors than lipid peroxides influence the development and/or prevention of atherogenesis, such as the amount of saturated fat, amount of mono- or polyunsaturated fat, amount of carbohydrates and insulin response, etc. Phytoestrogens: plant analogues of the hormone estrogen. Although most of the non-washed rice is new grain with less impurities and relatively clean, in order to be assured of safety, the non-washed rice that has been stored for some . Predominantly Raw In tests feeding high-cholesterol diets to rabbits, the consumption of scrambled or baked eggs produced increases in serum cholesterol of 6-7 times the pre-existing levels, while fried or hard-boiled eggs raised levels by 10-14 times [Pollack 1958]. Pure aflatoxins (B1, B2, G1 and G2) were individually coated on a silica gel and exposed to microwaves at various power settings and periods. These contain oxalates, which among other effects inhibit calcium absorption. However, it is not carcinogenic, and has been shown to have anticarcinogenic properties in tests in vitro; see Hertog and Katan [1998], and Chung et al. From Liener [1994], soybeans contain some heat-labile protease inhibitors and hemagglutinins. When you have aflatoxin in your product and it is above the maximum level than the only option is to destroy the product. The foods and crops most likely to be contaminated with aflatoxin include: peanuts. Also, soaking/germination (sprouting) reduces phytates [Hurrell 1997]. Aflatoxins can cause both acute and chronic toxicity. What Are Apergillus and Aflatoxins? 5. Thus if cholesterol and/or oxidized cholesterol are in fact atherosclerotic in effect, then the implication is that there must be something else in the diets/lifestyles of hunter-gatherer groups mitigating or negating this effect. Remark: We do not recommend worrying excessively about completely avoiding (all of) the foods listed below, first of all because the list is not exhaustive and toxins are quite widespread in nature. The effect of . Again, they are not hazardous unless large quantities are eaten. It is NOT possible to . Note here that the monkeys were fed semi-purified diets, with a canavanine content of 1-2%, versus a typical canavanine content of 1.5% (dry weight--that is, when completely dehydrated) for alfalfa sprouts [Malinow 1982]. In plants, flavonoids serve a number of functions: as pigments (the color of fruits and flowers is due to flavonoids), antioxidants, sunscreens, etc. Fava beans. Depending on the situation, the benefits of a food or class of foods may mean more for the health of the body than whatever associated negatives there may be--or vice versa. Role of oxidized LDL cholesterol in atherogenesis. Animals should not consume any level of aflatoxin in their diet for at least three weeks prior to slaughter. Soy also contains factors that are relatively heat-stable, though of lesser significance, such as: From Marth [1990], mycotoxins (toxins produced by molds) are completely destroyed at their melting point, which is generally at high temperatures: 164C (327F) for Zearalenone, 170C (338F) for Rubratoxia. Buy (and Eat) Selectively: Always avoid eating nuts that look moldy, discolored or shriveled. Our goal, rather, is to show that one needn't be excessively concerned about potential harmful effects of the chemical constituents created by cooking, since all living animals are naturally exposed to quite a variety of toxins in the foods they eat anyway. What diet pattern increases risk of aflatoxin exposure. This is in marked contrast to the high levels of atherosclerosis in Western diets containing cooked meat. "Heating and cooking under pressure can destroy nearly 70% of aflatoxin in rice compared to under atmospheric pressure only 50% destroyed (37)". These contain oxalates, which among other effects inhibit calcium absorption. There are currently over 300 varieties of reported mycotoxins confirmed to exist. According to the FDA regulatory levels for aflatoxin in the feed, the maximum allowable aflatoxin levels are 300, 100 and 20 g/kg for finishing cattle, swine and poultry, breeding cattle, and other animals respectively [16]. When mycotoxins are contaminated into foods, they cannot be destroyed by normal cooking processes. Alfalfa Sprouts Depending on the situation, the benefits of a food or class of foods may mean more for the health of the body than whatever associated negatives there may be--or vice versa. In almonds, the source of the contamination is from the soil, previously infested almonds (mummy nuts), and Navel Orangeworm (NOW) or other pests. Zearalenone ("zear") and aflatoxin both have immune lowering effects. Beans cooked at 100C (212F) for 30 minutes, and incorporated at a level as high as 20% of diet, do not retard growth when tested against casein. When washing the rice, it can remove 80% of the aflatoxin by scrubbing it three or four times. Finally, we notice that with the Paleolithic diet, which is not an all-raw diet, foods that are not edible raw are avoided but for different reasons than toxicity per se. Alfalfa sprouts contain approximately 1.5% canavanine, a substance which, when fed to monkeys, causes a severe lupus erythematosus-like syndrome. Of particular note here is the example of hunter-gatherer societies, where the incidence of heart disease is extremely low (perhaps the lowest that has been seen among human groups), despite the fact that relatively large amounts of cooked meat are consumed. Aflatoxins CAS No. (Refer to the previous section on Mutagenicity and Carcinogenicity, subtopic ". Let us look at an example using cooking oil made from corn contaminated with mycotoxins. These contain oxalates, which among other effects inhibit calcium absorption. (See Part 3's discussion of hunter-gatherers for a look at some of their food preparation practices; as well as another site link, Hunter-Gatherers: Examples of Healthy Omnivores, for a look at disease incidence.) (Lesson of the Pottenger's Cats Experiment: Cats Are Not Humans) Parsnips contain psoralens at a concentration of 40 . "Alien" proteins vs. cooked forms of proteins. Aflatoxins cannot be destroyed by cooking or processing food as they are very stable and are capable of surviving relatively high temperatures. Aflatoxins can occur in foods such as groundnuts, tree nuts, maize, rice, figs and other dried foods, spices , crude vegetable oils and cocoa beans, as a result of fungal contamination before . Additionally, raw egg white contains avidin, which binds to biotin and can impair metabolism of other B-vitamins. Zearalenone can induce thymic atrophy and macrophage activation. [1989] for a detailed overview of current knowledge in this field. How to cite this article: Vankayalapati V K. Aflatoxins: Properties, Toxicity and Detoxification. (Lesson of the Pottenger's Cats Experiment: Cats Are Not Humans) Our goal, rather, is to show that one needn't be excessively concerned about potential harmful effects of the chemical constituents created by cooking, since all living animals are naturally exposed to quite a variety of toxins in the foods they eat anyway. 1979, Kummerow 1993, Kubow 1993, O'Keefe et al. This is in marked contrast to the high levels of atherosclerosis in Western diets containing cooked meat. . Only after the LDL has been modified (through oxidation or glycosylation) does it activate differentiation and migration of macrophages. The biochemical processes that make oxidized fats atherogenic are the subject of scientific controversy; however, one suggestion is that the heating of fats, oils, and cholesterol increases the levels of lipid peroxide products. Beyond Veg home|Feedback|Links. In this study, the health risk among different age groups of Vietnamese population in the Mekong Delta, Vietnam was evaluated through rice consumption. Canavanine is an analog for the amino acid arginine, and takes its place when incorporated into proteins. [1995, p. 72], and Table 1 in Steinberg et al. Extrusion of cornmeal decreases AFBs content by 80.5 to 83.7% and . High temperatures and humid climates or stressful conditions like drought make the environment favorable for these fungi to produce aflatoxins. [1995] and Steinberg et al. Because of the large number of compounds in this class, generalizations about the function of flavonoids are difficult [McClure 1975]. 70, 72] explain the role of oxidized cholesterol in atherogenesis as follows: The oxidative modification of LDL cholesterol seems to be the final common pathway in the process of atherosclerosis. Flavonoids are a broad class of compounds common in plants and in the human diet. An aspergillus . Soaking under optimal conditions (55C, pH 4.5-5.0) can eliminate phytates [Sandberg and Svanberg 1991]. Because of the large number of compounds in this class, generalizations about the function of flavonoids are difficult [McClure 1975]. What is the maximum acceptable level of aflatoxins? Parsnips contain psoralens at a concentration of 40 ppm, and Ivie [1981, p. 910] reports: Dogs generally get aflatoxin poisoning through eating contaminated foods. Aflatoxin is a naturally occurring byproduct of mold that affects many crops. Heated Fats In turn, contaminated crops can cause problems such as miscarriage in pigs when fed to them as fodder. GO TO PART 3 - Discussion: 100% Raw vs. Thus if cholesterol and/or oxidized cholesterol are in fact atherosclerotic in effect, then the implication is that there must be something else in the diets/lifestyles of hunter-gatherer groups mitigating or negating this effect. Can aflatoxin be destroyed by cooking? GO TO PART 3 - Discussion: 100% Raw vs. O'Keefe et al. SEE TABLE OF CONTENTS FOR: PART 1 PART 2 PART 3 Phytoestrogens: plant analogues of the hormone estrogen. A. flavus and A. parasiticus can contaminate crops in the field, at harvest, and during storage. (See Part 3's discussion of hunter-gatherers for a look at some of their food preparation practices; as well as another site link, Hunter-Gatherers: Examples of Healthy Omnivores, for a look at disease incidence.) 003 Nutrition & Food Science International Journal radiation [9]. 70, 72] explain the role of oxidized cholesterol in atherogenesis as follows: Aflatoxins are not destroyed by normal food processing practices, such as fermenting, boiling, cooking or baking. Here it should be noted that some aspects of the effects of oxidized cholesterol are controversial in the sense that a scientific consensus has not yet been reached. Spinach and Rhubarb As mycotoxins cannot be completely destroyed by cooking, prevention is key. . Oxidizing agents readily destroy aflatoxin, and treatment with hydrogen peroxide may be useful. Since these varieties are very special and can't be found at the grocery, we won't expand further. Over 4,000 flavonoids are known, and new ones are being researched and described [Hollman 1997]. When in contact with stomach acids, the cyanogenic glycosides release cyanide, which is the active component in Zyklon B (used by the Nazis in death camps). The antinutrients here (anti-amylases, phytates) are affected by heating, but phytates require other processing (such as fermentation) for further neutralization, which is still only partial. GO TO PART 2 - Does Cooked Food Contain Less Nutrition? Aflatoxins are some of the most carcinogenic toxins known to man, and they can be found in foods today. [1995, pp. Aflatoxin is commonly found in poorly stored food crops such as cassava, chilli peppers, millet, rice, sorghum, sunflower seeds, beans, cocoa beans, soya beans, coffee beans, wheat and hay. In animals, their effects vary with the dose, length of . Because of the large number of compounds in this class, generalizations about the function of flavonoids are difficult [McClure 1975]. The general point here is to keep in mind that, before attempting to form conclusions that might be premature, it is important to view the role of any one factor in the equation of health in the context of the overall diet rather than in isolation. milk and cheese (rarely, meat can also become contaminated due to the spreading in aflatoxin in livestock feed) nuts (especially almonds, Brazil nuts, pecans, pistachios and walnuts) grains including quinoa ( 8) Contains some trypsin inhibitors and lectins, which are destroyed by heat [Seo 1990]. Aflatoxin is stable and heat resistant. (8,9) Oxidative modification of cholesterol occurs by means of oxygen free radical processes. Taro These contain toxic psoralens, which are potent light-activated carcinogens and mutagens not destroyed by cooking [Ivie 1981]. [1995, p. 72], and Table 1 in Steinberg et al. Alkaline chemicals are used in the deoxidation process, and these would destroy the majority of the mycotoxins in our theoretical cooking oil made from contaminated corn. 1994]. Contains some trypsin inhibitors and lectins, which are destroyed by heat [Seo 1990]. In tests feeding high-cholesterol diets to rabbits, the consumption of scrambled or baked eggs produced increases in serum cholesterol of 6-7 times the pre-existing levels, while fried or hard-boiled eggs raised levels by 10-14 times [Pollack 1958]. It is NOT possible to inactivate aflatoxin by heating your product. (Lesson of the Pottenger's Cats Experiment: Cats Are Not Humans) Steinberg et al. [1995, pp. Mushrooms How to Avoid. GO TO NEXT PART OF ARTICLE (In particular, those rawists who juice sprouts should probably strictly limit or avoid the consumption of alfalfa sprout juice, due to the concentration effect that results from juicing.) Sometimes grains can smell mouldy due to fungal contamination, when moisture content of the contaminated produce is still high. Aflatoxin is stable and heat resistant. SEE REFERENCE LIST Exposure of aflatoxin contaminated groundnut oil to sun light has given very promising results as it destroyed about 99 percent of the aflatoxins (4). Oxidized fats, oils, and cholesterol. Readers are encouraged to consult O'Keefe et al. Aflatoxin-producing fungi can contaminate crops in the field, at harvest, and during storage. How does aflatoxin denature? Frying in oil and standard methods of rice cooking also similarly eliminate almost no mycotoxins. Saponins. Major differences are to be found in consumption levels of saturated and polyunsaturated fats, preformed long-chain fatty acids, protein, carbohydrate, phytochemicals, etc., as well as in exercise levels.) The aflatoxins they produce are commonly . However, alfalfa that is cooked by autoclaving (i.e., subjected to pressure-cooking) doesn't induce this effect [Malinow 1982, Malinow 1984]. Viewing single factors out of context can be misleading. Additionally, raw egg white contains avidin, which binds to biotin and can impair metabolism of other B-vitamins. Yes, molds can thrive in high-acid foods like jams, jellies, pickles, fruit, and . SEE TABLE OF CONTENTS FOR: PART 1 PART 2 PART 3 GO TO NEXT PART OF ARTICLE [1998]. Here it should be noted that some aspects of the effects of oxidized cholesterol are controversial in the sense that a scientific consensus has not yet been reached. Parsnips contain psoralens at a concentration of 40 ppm, and Ivie [1981, p. 910] reports: [1989, p. 917]. Agent Stability. Of specific interest regarding the subject of oxidized cholesterol is that while hunter-gatherers eat roughly the same amount of cholesterol (480 mg) as in the modern Western diet [Eaton 1992] (from meat, presumably cooked), their serum cholesterol levels, as measured in five modern hunter-gatherer groups, averaged a very low 123.2 mg/dL [Eaton 1992]. 1994]. Viewing single factors out of context can be misleading. The scavenger receptors on the macrophages recognize oxidized LDL (but not unmodified LDL) and allow for subsequent phagocytosis. Other Examples Of particular note here is the example of hunter-gatherer societies, where the incidence of heart disease is extremely low (perhaps the lowest that has been seen among human groups), despite the fact that relatively large amounts of cooked meat are consumed. It is also worth remarking that many other factors than lipid peroxides influence the development and/or prevention of atherogenesis, such as the amount of saturated fat, amount of mono- or polyunsaturated fat, amount of carbohydrates and insulin response, etc. Sorting methods can be broadly categorized into methods which use machines to eliminate unwanted plants and methods in which people eliminate unwanted plants (hand-picking). How do you get rid of aflatoxins in peanuts? 1 Aflatoxin prevention tips. From the Paleolithic diet point of view, it is more important to avoid "alien" proteins that cause problems via molecular mimicry (i.e., autoimmune reactions) than to avoid cooked forms of proteins we are adapted to. Can aflatoxin be destroyed by cooking? [19] If you have low immunity (low T-cells, low white blood cell count, and so forth), immediately go off moldy food suspects. Beyond Veg home|Feedback|Links, Soybeans. SEE REFERENCE LIST [1989] for a detailed overview of current knowledge in this field. Back to Research-Based Appraisals of Alternative Diet Lore Egg Whites Predominantly Raw However, there have been many recent advances in food processing developed to keep final food products safe and healthy, . O'Keefe et al. . Steinberg et al. Aflatoxin is the main mycotoxin that harm animal and human health due to its carcinogenic nature. (See Part 3's discussion of hunter-gatherers for a look at some of their food preparation practices; as well as another site link, Hunter-Gatherers: Examples of Healthy Omnivores, for a look at disease incidence.) (8,9) Oxidative modification of cholesterol occurs by means of oxygen free radical processes. Consumption of 0.1 kg of parsnip root could expose an individual to 4 to 5 mg of total psoralens, an amount that might be expected to cause some physiological effects under certain circumstances Such individuals carry a polymorphism of a gene (present in some regions where malaria is prevalent) that is thought to protect against malaria but also results in severe deficiency of glucose-6-phosphate dehydrogenase (G6PD) [Golenser 1983]. Thus, although it would be very difficult for a human to eat enough fresh alfalfa sprouts to ingest even 1% canavanine, individuals should be aware of the potential risks, and consume (or not consume) alfalfa sprouts accordingly. SEE REFERENCE LIST Thus, there is an optimal heat treatment, which was found to be 120 minutes at 140C (284F), or 30 minutes at 160C (320F). Again, they are not hazardous unless large quantities are eaten. GO TO NEXT PART OF ARTICLE Antivitamins. GO TO PART 3 - Discussion: 100% Raw vs. Canavanine is an analog for the amino acid arginine, and takes its place when incorporated into proteins. The idea is that the peroxides (in combination with lipids) promote an atherogenic response [Kubow 1993]. The event which served as the impetus for the growth of mold research in Japan was the occurrence of the so-called yellow rice incidents. Cyanogenic Glycosides This divergence may be due to the differences between the type of meat (wild game) in hunter-gatherer diets--which in general is quite lean--compared to modern domesticated meats (five times less fat, and one-fifth to one-sixth as saturated [Eaton 1996]), and/or the difference may be due to a range of other factors. Edema. Potatoes contain solanine and chaconine, which are not hazardous unless large quantities are eaten. The most common way to remove AFB1 using physical methods is to heat and use gamma rays. (In particular, those rawists who juice sprouts should probably strictly limit or avoid the consumption of alfalfa sprout juice, due to the concentration effect that results from juicing.) The paradox of relatively high cholesterol intake and cooked meats vs. rarity of heart disease in hunter-gatherer groups. Aflatoxin cannot be destroyed by cooking or processing. Aflatoxins are also known to cause liver damage and liver failure in animals. Mycotoxin survival rate (%) after cooking shown in parentheses. However, when beans which have been cooked at the lesser temperature of 70C (158F) for 30 minutes are incorporated, growth retardation is almost as great as that which occurs when raw beans are fed. (NB. Thus if cholesterol and/or oxidized cholesterol are in fact atherosclerotic in effect, then the implication is that there must be something else in the diets/lifestyles of hunter-gatherer groups mitigating or negating this effect. Readers are encouraged to consult O'Keefe et al. Mushrooms When in contact with stomach acids, the cyanogenic glycosides release cyanide, which is the active component in Zyklon B (used by the Nazis in death camps). Role of oxidized LDL cholesterol in atherogenesis. That nutritional benefits from foods, whether raw or cooked, unavoidably come at the expense of costs and tradeoffs is a central issue that we will return to more than once, in different forms, as this paper proceeds. [1995] and Steinberg et al. Control at source is the most effective means for . Let's mention quickly a few other examples: pyrrolizidine alkaloids, present in herbal teas, are carcinogenic, mutagenic, and teratogenic (cause birth defects); gossypol in cottonseed causes abnormal sperm and male sterility, and is a carcinogen; piperine in black pepper causes tumors in mice; capsaicin in hot pepper is a mutagen; allyl iosthiocyanate, in oil of mustard and horseradish, is a carcinogen in rats; quinones and their phenol precursors (in many different plants) have mutagenic and antimutagenic properties. [1995, p. 72], and Table 1 in Steinberg et al. When eating peanuts and other nuts at home, it is safest to avoid eating those which are moldy, which have holes in them, which taste bitter when eaten, or which are not mature. Predominantly Raw (8,9) Oxidative modification of cholesterol occurs by means of oxygen free radical processes. There are two methods of drying i.e., sun drying (natural drying) and artificial drying (mechanical drying). (Lesson of the Pottenger's Cats Experiment: Cats Are Not Humans) ("Heat-labile" means those susceptible to changes by heat; a hemagglutinin is something that causes red blood cells to clump together.) Research reveals that in animal models, oxidized fats, oils, and cholesterol induce higher levels of arterial plaque (i.e., atherogenesis) than do the corresponding non-oxidized fats, oils, and cholesterol [Taylor et al. Some flavonoids protect against the mutagenic effect of other substances. Since these varieties are very special and can't be found at the grocery, we won't expand further. GO TO PART 3 - Discussion: 100% Raw vs. That means products such as peanut butter or corn chips can be equally as contaminated as plain peanuts or corn. Spinach and Rhubarb Cleaning is a multistep process which removes the Finally, we notice that with the Paleolithic diet, which is not an all-raw diet, foods that are not edible raw are avoided but for different reasons than toxicity per se. 7 The four most common aflatoxins are B1, B2, G1 and G2, with the B1 most potent liver toxin and classified as class I carcinogen for humans.
