Science Underscores the Grassfed Story
Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Good science is based on Critical Thinking. There is a tremendous quantity of information on the Internet. Some of the more popular sources are not science based. They are literally opinions that have gained broad based acceptance among some people.
Just because many people believe something, that does not make it true. Some of the greatest myths or our era that are being spread on the internet have to deal with nutrition. From simple things like what is, and is not, good food for man to far more complex issues such as organic, GMO, contaminants, etc.
Some people see this Science Links section of our Website as a major myth busting exercise that is quite disturbing. They want to believe their myths because their favorite myths provide comfort and all too often support their lifestyle choices. If you are interested in the truth, then buckle your seat belt and take a ride down through these amazing links. Topics include nutrition, evolutionary development of man, mycotoxins, molds, GMO (genetics), organics (chemistry and contaminants), and much more.
For most of the links on this page, when you select them, you will leave this site.
Here are four papers (three downloads and one link) by Artemis P. Simopoulos, M.D., President, The Center for Genetics, Nutrition and Health, Washington, DC. She says things like; “Today industrialized societies are characterized by (1) an increase in energy intake and decrease in energy expenditure; (2) an increase in saturated fat, omega-6 fatty acids and trans fatty acids (partially hydrogenated oils), and a decrease in omega-3 fatty acid intake; (3) a decrease in complex carbohydrates and fiber; (4) an increase in cereal grains and a decrease in fruits and vegetables; and (5) a decrease in protein, antioxidants and calcium intake.” Click here to return to The Real Diet of Man.
Volumes in this series consist of exceptionally thorough reviews on topics selected as either fundamental to improved understanding of human and animal nutrition, useful in resolving present controversies, or relevant to problems of social and preventive medicine that depend for their solution on progress in nutrition. Many of the individual articles have been judged as among the most comprehensive reviews ever published on the given topic. Since the first volume appeared in 1959, the series has earned repeated praise for the quality of its scholarship and the reputation of its authors.
Dr. Artemis P. Simopoulos is the founder and president of the Center for Genetics, Nutrition and Health, a nonprofit educational organization in Washington, DC, since 1990. Dr. Simopoulos was a founding member of the International Society for the Study of Fatty Acids and Lipids (ISSFAL) in 1991, secretary/treasurer of ISSFAL from 1991 to 1998, and a member of the editorial board of the ISSFAL newsletter from 1994 to 2000. She is the founder and president of the International Society of Nutrigenetics/ Nutrigenomics (ISNN) and founder and chair of the World Council on Nutrition, Fitness and Health (WCNFH) since 2005.
Dr. Hibbeln has extensive international collaborations for clinical trials of omega-3 fatty acids for the prevention of suicide, postpartum depression, and violence. He is a primary collaborator in the Avon Longitudinal Study of Parents and Children, Bristol, UK, examining the residual effect of nutritional insufficiencies in pregnancy in childhood neurodevelopmental outcomes and relevant gene-nutrient interactions. Full Abstracts of many peer-reviewed scientific reports are available through this link.
People all around the world have been finding out about their Omega 3 levels with our tests and because of this they are finding new ways to prevent cardiovascular disease, inflammation, improve brain function and much more. Those of us here at Slanker's highly recommend that everyone take this test. After you take the test, then check in with us and let's compare results.
The period of growth between germination and flowering is known as the vegetative phase of plant development. During the vegetative phase, plants are busy carrying out photosynthesis and accumulating resources that will be needed for flowering and reproduction. Different types of plants show different growth habits. The movies in this link will document various growth processes that occur during the vegetative phase of development.
The Max-Planck-Institute of Evolutionary Biology consists currently of two departments, Evolutionary Ecology and Evolutionary Genetics, which employ a variety of methods and approaches to do basic research in evolutionary biology. A third department in Evolutionary Theory has been newly created.
OEB is in the scholarly pursuit of a broad range of research and teaching interests. These span field and laboratory studies that are key to understanding the evolution of organisms, how biodiversity is generated and maintained, how organisms work, and how organisms interact with their environment. These also span from the evolution and control of gene expression patterns within individuals and populations to the dynamics of ecosystems.
Created in April 1998 as the "Virtual Department of Biological Anthropology," the BioAnth website was established as a forum for information on and discussion of topics related to broadly defined aspects of biological and cultural human variation and adaptation.

This web site is dedicated to bringing you the excitement, latest findings, and profound implications of the scientific exploration of human origins. Check out the page on Tools and Food.
Dr. Loren Cordain is a member of the faculty of the Department of Health and Exercise Science at Colorado State University. During the past two decades he has researched the effects of diet on human health and specifically examined links between modern diets and disease. He has revealed significant evidence that human health is optimally maintained through consumption of a diet that closely resembles our Paleolithic ancestors, consisting of grass-fed meats, fish and seafood, fresh fruits, and fresh vegetables. Additional information and specifics may be found in the articles, books, and materials listed on this Web site.
Zookeepers learned long ago that in order for an animal not just to exist but to thrive, be healthy and reproduce in captivity, it was necessary to replicate as closely as possible in the zoo the animal's natural habitat. Part of that requirement was diet. This is a well-written article that explains the Paleo approach to diet by Dr. Loren Cordain, a member of the faculty of the Department of Health and Exercise Science at Colorado State University.
This resource contains more than 40 peer-reviewed, published research reports. For example, the abstract for one reads like this: Both anthropologists and nutritionists have long recognized that the diets of modern-day hunter-gatherers may represent a reference standard for modern human nutrition and a model for defense against certain diseases of affluence. Because the hunter-gatherer way of life is now probably extinct in its purely un-Westernized form, nutritionists and anthropologists must rely on indirect procedures to reconstruct the traditional diet of preagricultural humans.
Research spanning three decades suggests that grass-based diets can significantly improve the fatty acid (FA) composition and antioxidant content of beef, albeit with variable impacts on overall palatability. Grass-based diets have been shown to enhance total conjugated linoleic acid (CLA) (C18:2) isomers, trans vaccenic acid (TVA) (C18:1 t11), a precursor to CLA, and omega-3 (n-3) FAs on a g/g fat basis.
This is an interesting study, but it does indicate that in many studies the cattle are not really grass-fed and the grain-fed cattle are only partially so. That's because the researches don't know enough about the livestock business to ask the right questions. Also, some variations occur from the analytical methods used and what parts of the animal were analyzed. The differences between eating grass and being fed hay are also a question, but the grains have relatively uniform differences in EFA profiles. So if a steer is fed 160 days an 80% grain ratio (the standard mix and the grain portion is usually corn) then it's EFA ratio should be up around 15 : 1. In a feedlot steers gain about 3.2 pounds per day. So in 160 days they gain 512 pounds which is about a 68% increase in body mass.
In one ounce of corn there is: Total Omega-3 fatty acids 18.2 mg and Total Omega-6 fatty acids of 587 mg.
At the average weight in the feedlot (1000 pounds) the steer will eat 2.6% of body weight or 26 pounds of feed with 20.87 pounds of it being corn. With that kind of intake, and with the knowledge that the O6 overloads block the absorption of O3, one has to imagine significant change in the O6 direction, more than the studies suggest.
Only one study indicated a 1.44 to one ratio for grass-fed and it's grain-fed ratio was 3 : 1. To me, that means that particular study was flawed from the onset.
Raw red muscle meat contains around 20-25 g protein/100 g. Cooked red meat contains 28-36 g/100 g, because the water content decreases and nutrients become more concentrated during cooking. The protein is highly digestible, around 94% compared with the digestibility of 78% in beans and 86% in whole wheat. (9) Protein from meat provides all essential amino acids (lysine, threonine, methionine, phenylalanine, tryptophan, leucine, isoleucine, valine) and has no limiting amino acids. Protein Digestibility Corrected Amino Acid Score is a method of evaluating the protein quality, with a maximum possible score of 1.0. Animal meats like beef have a score of approximately 0.9, compared with values of 0.5-0.7 for most plant foods. (10) The amino acid glutamic acid/glutamine is present in meat in the highest amounts (16.5%), followed by arginine, alanine and aspartic acid.
Mycotoxins are poisonous substances produced by certain molds found primarily in grain and nut crops, but are also known to be on celery, grape juice, apples, and other produce. There are many of them and scientists are continually discovering new ones. The Food and Agriculture Organization (FAO) of the United Nations estimates that 25% of the world's food crops are affected by mycotoxins, of which the most notorious are aflatoxins.
Aflatoxins are considered unavoidable contaminants of food and feed, even where good manufacturing practices have been followed.

Schering-Plough Corporation, Enzon Pharmaceuticals, and Merck & Co., Inc. sponsor this very informative Web site focused entirely on fungi and molds. Dr. Fungus is an independent Web site dedicated to providing a wide range of scholarly peer-reviewed contemporary and historical information regarding fungi. It seeks to promote an understanding of fungi and the ways that fungal diseases of humans, animals, and plants affect people living throughout the world. It provides information to both professionals and the public by making a broad range of mycology-related images and content instantly available via the World Wide Web.
In the germ world, fungi usually lack the flair of viruses or bacteria. To people with normal, healthy immune systems, a fungus will rarely show itself — even though you carry around a microscopic film of fungus on your hair and skin, and take in invisible clouds of fungal spores with each breath. While many other microbes prefer to make a living through disease and death, a fungus is often content to wait for its host to die of something else.
In such diseases, the fungi are actively growing on and invading the body of their hosts. There is another means by which fungi can cause harm without invading our bodies. When fungi grow on a living organism or on stored food material that we consume, they may produce harmful metabolites that diffuses into their food. It is believed that fungi evolved these metabolites as a means of protecting their food supply by preventing other organisms from eating it. These metabolites are referred to as mycotoxins, which literally means "fungus poisons." From the Botony Department of the University of Hawaii.
Mycotoxins contaminate cereal grains worldwide, and their presence in pet food has been a potential health threat to companion animals. Aflatoxins, ochratoxin A, and Fusarium mycotoxins have been found in both raw ingredients and final products of pet food around the globe. Aflatoxin, a hepatotoxin and carcinogen, has caused several food poisoning outbreaks in dogs, and aflatoxin content is regulated in pet food in many countries. Ochratoxin A and Fusarium mycotoxins including trichothecenes, zearalenone, and fumonisins may have chronic effects on the health of companion animals.
The topic "Mycotoxins" and all related subjects can be very complicated and often lead to unanswered questions. www.mycotoxins.info attempts to cover these issues comprehensively and offers useful information to everybody who might be confronted with problems that can be attributed to mycotoxins.
Food-borne bacteria rightly are a major cause for concern to human health, but it is difficult to escape the conclusion that mycotoxins in foods are responsible for much higher numbers of human deaths than are food-borne bacteria.
This is a link to a pdf document of a research report published by Kansas State University discussing the cause and other aspects of mycotoxins in grains. The author is Tim Herrman. The publication date was May 2002.
What goes for animals also goes for people as you'll see in this article. Grains for people are just as likely to contain fungi and molds are grains for animal feeds, such as dog food. Mycotoxins are toxins produced by molds that can affect the health of animals in many ways. These mycotoxins can be present in hay, pasture, and grain. Mycotoxins are stable chemical compounds, they are resistant to heating and can remain in the feed for an extended period of time.
Among food contaminants, mycotoxins will have greater consequences in terms of both human and animal health as well as economics. Mycotoxins are substances produced by molds that contaminate various agricultural commodities either before harvest or under post-harvest conditions.
Mercury is a highly toxic element that is found both naturally and as an introduced contaminant in the environment. Although its potential for toxicity in highly contaminated areas such as Minamata Bay, Japan, in the 1950's and 1960's, is well documented, research has shown that mercury can be a threat to the health of people and wildlife in many environments that are not obviously polluted. The risk is determined by the likelihood of exposure, the form of mercury present (some forms are more toxic than others), and the geochemical and ecological factors that influence how mercury moves and changes form in the environment.
Nearly all food borne illnesses come from organic sources. They are bacteria, viruses, molds, and fungi. Grains and sugars are organic, yet they are very destructive to human health. These "organic" substances cause nearly all of the chronic diseases in America. But what if foods are grown "organically"? Is that truly better? This link goes to the American Council on Science and Health's review of a published report titled "Claims of Organic Food's Nutritional Superiority: A Critical Review." You can also access the actual report. This is definitely food for thought.
On the basis of a systematic review of studies of satisfactory quality, there is no evidence of a difference in nutrient quality between organically and conventionally produced foodstuffs. The small differences in nutrient content detected are biologically plausible and mostly relate to differences in production methods. From an extensive report published in the American Journal of Clinical Nutrition. A summery of the report at MSN Health.

This manuscript describes the effort of the ENCODE (Encyclopedia of DNA Elements) Consortium to examine the principles of human transcriptional regulatory networks, using a subset of 119 transcription factors. The results are integrated with other genomic information to form a multi-level meta-network in which different levels have distinct properties. The findings will aid future interpretations of human genomics and help us to understand the basic principles of human biology and disease.
AcademicsReview.org launches with point-by-point analysis of Jeffrey Smith’s claims against GMO foods and genetic engineering, holding each up to peer-reviewed, international science. The founders, two professors from the United States and Australia, invite other scientists to join the mission
A letter written by a Dr. Don Huber to Secretary of Agriculture Vilsack has been making the rounds on the "net." The letter was allegedly given to the Farm and Ranch Freedom Alliance, and they claim to have confirmed that it was written by Dr. Huber. You can find the full text of the letter on the FRFA site with the ominous title Researcher: Roundup or Roundup-Ready Crops May Be Causing Animal Miscarriages and Infertility.
The story has been picked up by many bloggers and even made an appearance on Reuters. Where are the posts dedicated to a critical analysis of the letter? Instead there is a rush to assume that it is correct, despite the lack of citations or other evidence provided for the extraordinary claims in the letter. Here is a rebuttal.
Humans have been altering the genetic makeup of plants for millennia, keeping seeds from the best crops and planting them in following years, breeding and crossbreeding varieties to make them taste sweeter, grow bigger, last longer.
Whether biotech foods will deliver on their promise of eliminating world hunger and bettering the lives of all remains to be seen. Their potential is enormous, yet they carry risks — and we may pay for accidents or errors in judgment in ways we cannot yet imagine. But the biggest mistake of all would be to blindly reject or endorse this new technology.
Dr. Mehmet Oz has repeatedly allowed Jeffrey Smith, an activist with no scientific or medical background or other relevant credentials, to appear on his program and make claims that GMOs are somehow associated with human health and safety risks. Viewers of this and similar Dr. Oz productions with Jeffrey Smith are being presented with highly inaccurate and irresponsible health-related advice.
There is no compelling evidence of any harm arising from eating GMOs. Yet, opponents of GMOs are so sure that GMOs are dangerous that any study suggesting they are safe must have been funded by Monsanto, and any scientist pointing out the holes in their arguments must be an industry shill. In the anti-GMO universe, it often seems that the best evidence that something must be true is the existence of multiple experiments showing it is false.
This is a normal - and even healthy - reaction that indicates that parasites, fungi, viruses, bacteria or other pathogens are being effectively killed off.
Dry food — kibble — is the worst possible food you can feed to your cat. It is a moneymaking venture of pet food manufacturers that is leading to horrible chronic disease in cats. It is marketed as a product that is 100 percent nutritionally complete for all stages of your cat's life. That couldn't be further from the truth.
Candida overgrowth can cause many common symptoms of compromised health including fatigue, anxiety, depression, and impaired memory and concentration, and is also believed to play a role in the development of much more serious conditions such as mental disorders, autoimmune disease, and intolerance to a wide variety foods and chemicals. This is just the beginning of the list. Also on the list is heart disease, cancer (10,000 times worse!), obesity, and the list goes on and on and on.
The foods that humanity originally evolved to eat and those we now eat in modern civilization are in many cases significantly different--yet our basic underlying genetic inheritance remains basically the same as it was before, and has evolved only very slightly since then. Thus, many of the foods we now eat are discordant with our genetic inheritance.
Grass-fed beef, or beef produced from cattle fattened on forage only diets (little or no grain), has been reported to contain elevated concentrations of vitamin A, vitamin E, increased levels of omega-3, a more desirable omega-3:omega-6 ratio, and increased levels of conjugated linoleic acid (CLA), all substances with favorable biological effects on human health.
A Princeton University research team has demonstrated that all sweeteners are not equal when it comes to weight gain: Rats with access to high-fructose corn syrup gained significantly more weight than those with access to table sugar, even when their overall caloric intake was the same.
This is not a scientific article, but a synopsis of a book. "We think we know what to eat: less red meat and more fibre, less saturated fat and more fruit and veg, right? Wrong, according to a controversial new book by obesity researcher and nutritionist Zoe Harcombe. In 'The Obesity Epidemic: What Caused It? How Can We Stop It?' Harcombe charts her meticulous journey of research into studies that underpin dietary advice - and her myth-busting conclusions are startling."

The American Meat Institute put together a guide for consumers confused about recent claims made by some activists and media reports. It does explain many basic questions, yet in terms of addressing nutrition it misses the mark just like everyone else who recommends whole grains as a food.
Go to this link and read up on 56 afflictions troubling Americans and other grain eaters world wide that are caused and exacerbated by not eating the Paleolithic Diet.
The story on fat from grass-fed livestock is just the opposite of the story regarding the fat from grain-fed livestock. For years you've been told to avoid fat. But when it comes to grass-fed meats, the fat is good for you! We ran across a really good article covering the Big Picture on fats. For sure it debunks a lot of myths and old wives' tales. If you are concerned about saturated fats and/or fats in your food, don't miss this article.
The human body requires between five and ten grams of salt a day. Humans need a daily intake of salt. Unlike other chemicals that the body requires, sodium chloride, or salt, cannot be reproduced by the body. If the human body goes for a long period of time without enough salt the body will desiccate and die. So, is it time to end the war on salt?
Comprehensive, yet easy to understand, essays by Ted Slanker that provide an overview of the advantages of grass-based foods over grain-based foods.
Even though this study used grain-fed meats, it proves that even a little of the low-grain approach works best. The Atkins Diet doesn't emphasize grass-fed meats. If it had, the meat eaters in this study would have lost considerably more weight. But just the same, this study provides some guidance about how one should eat. The link takes you to an article summarizing the research. In that research you'll see that the low-fat, restricted-calorie diet based on the American Heart Association's guidelines was worse than the Mediterranean Diet. The Mediterranean Diet came in second to the Atkins Diet. All this strongly suggests that "The Diet of Man" is the one and only diet of man. It also suggests that the dietary information of the American Heart Association is merely the status quo of the failed science of 50 years ago.
Antibiotic resistance, the acquired ability of a pathogen to withstand an antibiotic that kills off its sensitive counterparts, originally arises from random mutations in existing genes or from intact genes that already serve a similar purpose. Exposure to antibiotics and other antimicrobial products, whether in the human body, in animals, or the environment, applies selective pressure that encourages resistance to emerge favoring both “naturally resistant” strains and strains which have “acquired resistance.” Horizontal gene transfer, in which genetic information is passed between microbes, allows resistance determinants to spread within harmless environmental or commensal microorganisms and pathogens, thus creating a reservoir of resistance. Resistance is also spread by the replication of microbes that carry resistance genes, a process that produces genetically identical (or clonal) progeny. (A report from the American Academy of Microbiology.)
All animals, including humans, naturally produce significant amounts of hormones during their lifetimes since hormones are needed for normal growth and functioning. The use of added hormones is carefully regulated by law.
Essay on nutrition written by Bonnie Beardsley, MPH, LDN, RD, a professional consulting dietitian.
Science versus the Popular Media
In no way can it be called science, but there was no other place to list Food, Inc. Because a lot of people believe the movie is gospel, it is listed. It claims it lifts the veil on our nation's food industry, exposing the highly mechanized underbelly that has been hidden from the American consumer with the consent of our government's regulatory agencies, USDA and FDA. It implies that our nation's food supply is now controlled by a handful of corporations that often put profit ahead of consumer health, the livelihood of the American farmer, the safety of workers, and our own environment. There are bigger-breasted chickens, the perfect pork chop, herbicide-resistant soybean seeds, even tomatoes that won't go bad, but it says there is also new strains of E. coli—the harmful bacteria that causes illness for an estimated 73,000 Americans annually. For these reasons and more Americans are riddled with widespread obesity, particularly among children, and an epidemic level of diabetes among adults.
This is an alliance of associations that represent the livestock, meat, and poultry industries. Together, their members produce more than 90% of U.S. beef, pork, lamb, veal, turkey, and chicken. U.S. meat and poultry is among the safest, most abundant and most affordable anywhere in the world. That success was achieved through research, technology, and plain hard work. The members are large and small, urban and rural, old-world and modern cutting edge. Despite this, the makers of "Food, Inc." and the subjects they interview seek to paint our industries as big, bad, and mechanized. They seek to prove their point though a selective use of the facts. While the makers of "Food, Inc." have the right to state their opinions, consumers and the media have the right to the facts. And that’s what this web site claims it is all about: the other side of the story.
Some of the descriptive words in my review include deception, misinformation, myths, lies, fabrications, and innuendoes. Am I referring to the movie or the food industry? Here’s a hint.
After seeing Food Inc. many viewers were inspired to seek out alternative food sources. We know, they called us. It was somewhat surprising though to learn that most of the new people did not realize that Slanker’s Grass-Fed Meats is all about nutrition. Plus they knew nothing about grass-fed meats. It made me wonder then, “Why did they call?”
I think my review will blow your mind. For an absolute fact my review will teach everyone more about America's food industry than what they could learn from the movie Food Inc.
This is not a scientific article either. Instead it follows along somewhat with this thought from Amanda Radke in an article she wrote for BEEF Magazine. She wrote: Barry Sears, author of “The Zone Diet,” says there are three “visceral” things in life – religion, politics and nutrition. “They're all based on belief systems and none like to be challenged.” Many people contact us and they are highly critical of The Real Diet of Man because it doesn't literally follow scripture. So, for those folks I found this article. I for one do not believe God stopped speaking to man 2,000 years ago. I believe He is talking to us today. Since there are seven billion people now, we are all learning more every day about His great works.
Purdue University News -- Eat Meat
Eat meat. That's the dietary advice given by a team of scientists who examined the dietary role of fat in a study that combined nutritional analysis with anthropologic research about the diets of ancient hunter-gatherer societies.
Purdue University News -- ADHD in Boys
Purdue University researchers have found that boys with low blood levels of essential omega-3 fatty acids, have a greater tendency to have problems with behavior, learning and health consistent with attention deficit hyperactivity disorder or (ADHD).
An essay on Attention Deficit Disorder by Teresa Gallagher. "...kids low in Omega-3 essential fatty acids are significantly more likely to be hyperactive, have learning disorders, and to display behavioral problems."
This is an essay by John Finnegan. "...Omega-3 fats are necessary for the complete development of the human brain during pregnancy..."
"CLA is a fatty acid found in beef and dairy fats. Scientific interest in CLA was stimulated in the late 1980s when a University of Wisconsin researcher discovered its cancer-fighting properties in a study of rats fed fried hamburger. CLA cannot be produced by the human body, but it can be obtained through foods such as whole milk, butter, beef, and lamb." So check out "Amazing Graze" an article on the USDA's Web site that was published in the Agricultural Research magazine.
Supplementing animal feed with antimicrobial agents to enhance growth has been common practice for more than 30 years and is estimated to constitute more than half the total antimicrobial use worldwide. The potential public health consequences of this use have been debated; however, until recently, clear evidence of a health risk was not available. Accumulating evidence now indicates that the use of the glycopeptide avoparcin as a growth promoter has created in food animals a major reservoir of Enterococcus faecium, which contains the high level glycopeptide resistance determinant vanA, located on the Tn1546 transposon. Furthermore, glycopeptide-resistant strains, as well as resistance determinants, can be transmitted from animals to humans.
This links to an article in the Center for Disease Control's "Emerging" Infectious Diseases journal. Emerging Infectious Diseases represents the scientific communications component of CDC's efforts against the threat of emerging infections. However, even as it addresses CDC's interest in the elusive, continuous, evolving, and global nature of these infections, the journal relies on a broad international authorship base and is rigorously peer-reviewed by independent reviewers from all over the world.
According to James Russell, USDA researcher working at Cornell, an all-grain diet is not natural to cattle. As ruminant animals, cattle are designed to consume and digest huge quantities of high-cellulose, low-nutrition grass. Diets of starchy, high-calorie grain trigger disorders in cattle that must be treated with antibiotics and other drugs...
The Eating Experience
So the health story is great, but what about the eating experience? Grass-fed beef is famous for being "chewy." Yes, grass-fed beef is leaner than grain-fed beef. But is that good? What about tenderness? Government grading specifications indicate that intramuscular fat and tenderness go hand in hand. Is that true? For the answer, check this out: The Meat Tenderness Debate.
Michael Pollan's book, The Omnivore's Dilemma: A Natural History of Four Meals, was released in early 2006. It is not scientific work. But in a novel way he tries to answer the question of what we should have for dinner. To find out, Pollan follows each of the food chains that sustain us -- industrial food, organic or alternative food, and food we forage ourselves -- from the source to a final meal, and in the process develops his version of the American way of eating. The first chapter is all about corn, yet corn is only one of the many grains destroying the health of many Americans. Unfortunately, Pollan has become a poster boy for the War on American Agriculture and from what I hear he is basically a vegetarian. Therefore he is actually part of the problem in solving the American health crisis rather than being a part of the solution. For more on that click on The War on American Agriculture and Ted Slanker's Food Inc. Review.
