In a three-decade survey of American eating habits, researchers reported that between 1965 and 1989-90, whole milk consumption fell from 66 to 99 percent among different racial and economic groups surveyed. Egg items declined 24 to 52 percent and red meat fell sharply 71 to 89 percent. However, cheese intake increased 72 to 271 percent, low-fat milk rose 92 to 607 percent, and poultry declined in some cases but more than doubled in others. Intake of dark green or orange vegetables rose 3 to 44 percent, and soy products rose 156 percent in wealthier respondents but declined or showed no change in poorer ones.

• Lunch Hour Declines - In a survey of the vanishing lunch hour, the National Restaurant Association found that nearly 40 percent of workers did not take a real lunch break. Forty-five percent took less time for lunch than before and on average spent 29 minutes on lunch. The average American also skipped lunch altogether 57 times a year, ate lunch in restaurants 48 times a year, bought lunch 26 times in cafeterias, and ate once from a vending machine. Meanwhile, more people are bringing their lunch from home. Some 43 percent of men and 34 percent of women brought food from home at least once every two weeks in 1996, an increase of one third since 1987.             Source: Donna St. George, "The Incredible Shrinking Meal," New York Times, April 16, 1997.

• Eating Out Increases - The number of Americans who eat out has increased 33 percent in the last 20 years. A recent USDA survey found that in 1994-95, 57 percent of the population consumed meals and snacks away from home on any given day, accounting for about half of their daily calorie and fat intake on average. The most popular foods eaten away from home were beverages, including sodas, coffee, and milk, as well as lettuce salads, burgers with or without cheese, and french fries. U.S. Department of Labor statistics, meanwhile, show that American households spend nearly 40 percent of their food dollar on food away from home compared with 20 percent in the early 1970s. About one third of those who eat out do so in fast food establishments (32 percent), followed by sit-down restaurants (27 percent) and grocery or convenience stores (24 percent).

Echinacea is a purple flower whose leaves and roots have traditionally been used by native peoples in North America to treat infections, colds, inflammation, sore throats, aches and pains, wounds, and snakebites. Today, echinacea is one of the principal natural herbal remedies, and medical studies have confirmed that it has strong antiinflammatory and antibiotic properties.

High in saturated fat and dietary cholesterol, eggs are associated with increased risk of heart disease, certain cancers, and other degenerative conditions. See Animal Wastes, Environment, World Hunger.

• Eggs Linked to Lung Cancer - In studies of men employed by the Western Electric Company in Chicago, researchers reported that men who ingested 500 milligrams or more of dietary cholesterol a day faced almost twice the risk of lung cancer as those who ate less than that amount. Eggs were cited as the chief cause.

Artificial electromagnetic fields (EMFs) are a hallmark of modern life. Homes, offices, schools, workplaces, and the environment as a whole are exposed to various waves and vibrations from modern technology that have an impact on our health. See Microwave, Nuclear Radiation.

•  Environmental and Health Effects of EMFs - In a comprehensive study on the health effects of EMFs, a medical writer evaluated everything from cellular phones and hair dryers to computers and high-power lines. E. Blake Levitt correlated EMFs with changing climate and weather cycles as well as daily ki energy flow, and summarized scores of medical studies on the debilitating effects of modern technology on agriculture and the environment.
“The higher frequencies used for radio, TV, radar, and cellular-phone transmission are of special concern. The transmission intensities are sometimes on the order of a billion times more powerful than what exists in nature; the frequencies transmitted are extremely specific; the waves are polarized; and the signals can be digitally and analogously modulated.” She cited evidence that technologies such as these may also be a major unrecognized cause of tree and crop damage, deforestation, abnormal weather patterns, and other environmental changes.
In addition to various cancers, Levitt cited medical evidence that EMFs may be associated with the sharp rise in Alzheimer’s disease, Parkinson’s disease, learning disabilities, Sudden Infant Death Syndrome, Gulf War Syndrome, and ALS (Lou Gehrig’s Disease). “The global population, human, animal, and vegetation alike, is an unwitting test subject as many of these EMF technologies continue to proliferate . . .” she concluded. “A whole new EMF era is dawning with virtually no safeguards in place and with all these myriad questions unanswered. ‘Wireless’ America is looming on the horizon. It will alter our ecosystem in a way never experienced before. The stakes may be higher than we know.”

• Alveoli Regenerated in Animals - Using a nutritional component, researchers have been able to reverse emphysema and regenerate alveoli, the small air sacs that are damaged by this degenerative lung disease. The dietary ingredient, retinoic acid, a derivative of vitamin A (found in many common vegetables and fruits), caused adult rats with emphysema-like conditions to repair damaged air sacs and return to normal. "For the first time, we have been able to induce the formation of alveoli," Dr. Donald Massaro, one of the scientists at the Georgetown University School of Medicine, reported.      Source: Warren E.

Personal and planetary health are inseparable. When we eat well, the planet benefits. When we eat poorly, the earth suffers. The natural foods and organic farming communities have been in the forefront of the environmental movement, demonstrating the connection between diet and ecology and the role the modern food and agriculture system, especially chemical pesticides, fertilizers, and other additives, plays in environmental destruction. See Animal Wastes, Chemicals, Cropland Loss, Electromagnetic Fields, Genetically Engineered Foods, Global Warming, Infectious Diseases, Infertility, Nuclear Radiation, Pesticides, Sewage Sludge, Soil Depletion, Water.

• Environmental Effects of Dietary Goals - In 1981 a panel of the American Association for the Advancement of Science met to evaluate the impact of implementing Dietary Goals for the United States. Beyond an improvement in public health, the symposium found that dietary changes would have far-reaching social and economic benefits. The scientists concluded that adoption of a diet centered on whole cereal grains rather than meat, poultry, and other animal foods would have significant effects on everything from land, water, fuel, and mineral use to the cost of living, employment rates, and the balance of international trade. Based on government and industry figures, the panel summarized its findings as follows:
Land: production of animal foods uses 85 percent (340/400 million acres) of all cropland, and 95 percent (1,230/1,300 million acres) of all agricultural land in the United States, and it is largely responsible for the extensive abuse of rangeland and forestland and for the loss of soil productivity through erosion and mineral depletion.
Water: production of animal foods uses nearly 80 percent of all piped water in the United States, and it is chiefly responsible for pollution of two-thirds of U.S. basins and for generating over half of the pollution burden entering the nation’s lakes and streams.
Wildlife: production of animal foods is responsible for extensive destruction of wildlife through conversion and preemption of forest and rangeland habitats and through massive poisoning and trapping of “predators.”
Energy: production, processing, and preparation of animal foods consumes approximately 14 percent of the national energy budget, which is roughly equivalent to the fuel needed to power all our automobiles, only a little less than our total oil imports, and more than twice the energy supplied by all our nuclear power plants.
Materials: processing and packaging of animal foods uses large amounts of strategically important and critically scarce raw materials including aluminum, copper, iron and steel, tin, zinc, potassium, rubber, wood, and petroleum products.
Food resources: 90 percent of our grains and legumes and approximately one half of the fish catch is fed to livestock, while 800 million people are going hungry.
Cost of living: meats generally cost five to six times as much as foods containing an equivalent amount of vegetable protein, and consumption of animal foods adds approximately $4,000 to an average household’s annual budget, including the cost of increased medical care.
Employment: production and processing of animal food has led to the centralization and automation of this industry, idling thousands of farm and food workers and small farmers.
International trade: the value of imports of meat and other animal foods, farm machinery fertilizers, and petroleum for production of animal foods is approximately equivalent to our national trade deficit of $40 billion.

• 1 in 8 Plants Imperiled - One of every eight plant species in the world is threatened with extinction, according to a comprehensive assessment by botanists and conservationists. The survey, which took 20 years to compile, added nearly 34,000 species to the World Conservation Union’s Red List of threatened life forms.
The scientists cited modern agriculture, which destroys large swaths of wild lands; logging; and the influx of species from one region to another where they grow out of control and overpower native plants as the principal causes for the decline.
Earlier, the conservation group had placed nearly one fourth of known mammal and bird species on the endangered list.
The U.S., with one in every three species threatened, led the nations in the number of plants facing extinction, followed by Australia, South Africa, Turkey, and Mexico.
Participants in the study included the Nature Conservancy, the New York Botanical Garden, and the Smithsonian Institution’s National Museum of Natural History.

• Plant vs. Animal-Quality Food - A researcher reported that the modern food and agriculture system uses vast amounts of oil and other fossil fuels. This includes the energy used in the manufacture of heavy farm equipment, chemical fertilizers and pesticides, and in processing and refining. The two major users of energy are the meat and meat products industry and the sugar industry followed by the beverage and soft drink industry. Altogether, per capita use of energy for modern food production and processing comes to the equivalent of 375.4 gallons of oil per year, or about 1 gallon of gasoline a day.

• Barbecued Beef Main Cause of  L.A. Smog - Hamburger and other barbecued meat may be the leading cause of urban air pollution, according to scientists at California Institute of Technology. Cooking beef in the backyard grill produces dozens of compounds including hydrocarbons, furans, steroids, and pesticide residues. The smoke from meat may be “the dominant source” of the fine organic particles that pollute city air. The particulates’ small size—2 microns or less—causes them to be more easily inhaled than other aerosols.

In a survey of leading organizations and individuals in the fields of nutrition and ecology including Frances Moore Lappé, author of Diet for a Small Planet; John Robbins, author of Diet for a New America; David Pimentel of Cornell University’s College of Agriculture; and Robin Hur, an Oregon-based researcher, Vegetarian Times summarized findings showing that a whole foods diet could contribute to a healthier planet:
• More than 50 percent of tropical rain forest deforestation (216,000 acres total per day) is linked with livestock production.
• An average of 55 square feet (a small kitchen) of forest is lost for every hamburger produced from cattle raised in former Central American rain forests.
• The current rate of species’ extinction from loss of tropical rain forests and related habitats is 1,000 per year.
• One acre of trees is saved each year by each person who switches to a vegan diet.
• The average amount of water required daily for a vegetarian who eats dairy food and eggs is about 1,200 gallons, about 25 percent the amount for someone eating the standard American diet. The amount of water required for a person on a dairy-free vegetarian diet is 300 gallons.
• About 85 percent of the topsoil loss in the U.S. is directly connected with livestock production.
• A reduction in meat consumption by only 10 percent would free enough
grain in the U.S. to feed an estimated 60 million people worldwide.
• More than 50 percent of the water pollution in the U.S. is associated with animal food production and chemical farming.
• Imported oil could be cut by 60 percent if the nation switched to a vegetarian diet.

• Soil Depletion - Failing soil is increasing at an alarming rate and may imperil the world’s food supply early in the 21st century. Every year for the next 20 years, an area the size of Alaska may lose its fertility and use, a new study sponsored by the UN Food and Agricultural Organization warned. Figures compiled by the International Soil Reference and Information Center reported that an area nearly the size of Western Europe has already lost its usefulness from overgrazing of cattle and other livestock, deforestation, and other human abuse. Another 2.25 billion acres—the size of Australia—has declined and needs restoration. Soil degradation annually claims 17.5 million acres, the size of Ireland. In Africa and Asia, 4 percent of land has lost its farm value; in Europe 2.3 percent; in South America 1.4 percent; and in North America, 1.3 percent.

People with E.I. are extremely sensitive to toxins, dust, chemicals, and other factors in their immediate environment. Improper diet is an underlying cause in some cases and a solution in others.

• Case History - In 1974 Sherry A. Rogers, M.D., then a 31-year-old physician, suffered from Environmental Illness. She had ugly red eczema over the lower half of her face, periodic asthma, recurrent sinus problems, wicked migraines, chronic back pain from an old riding injury, and unwarranted exhaustion and depression.
By the early 1980s she was having strong adverse reactions to chemicals such as workmen glueing down a new Formica countertop. She had treated her sensitivities with injections, multiple vitamins and ionizers, cotton blankets and pillows, bottled water, oxygen tanks, aluminum foil.
In 1987, after following a macrobiotic diet for six  months, she experienced major improvement. The excruciating shoulder pain disappeared, and over the next few months every chronic symptom that she ever had vanished. During the next few years, she gave up her allergy injections and could remain up to 14 hours a day in a toxic, smoke-filled environment.
“In three years she’ll be 50, yet she’s stronger and healthier now than she has ever been in her life,” concluded a profile in The Human Ecologist. “She takes no medications, no supplements, no injections, and for the first time in her life, has no symptoms.”

"Therefore, it appeared to these patients that the macrobiotic diet provided the additional unanticipated relief that they experi-enced, and should be considered for those with persistent symptoms triggered by chemical exposure.
"All things considered, it has clearly been a life-saver for many. And the beauty of it is that it is the least expensive of all therapies."

Estrogen, a major hormone produced in the ovaries, controls the development of female sex characteristics and plays an important role in reproductive health. Excess estrogen from eating dairy foods, taking birth control pills, or other dietary or chemical exposure is associated with higher risk for breast cancer, osteoporosis, and other diseases. See Breast Cancer, Chemicals, Infertility, Isoflavones, Me-nopause, Osteoporosis, Phytoestrogen.

• Plant Estrogen Superior to Animal Estrogen for Osteoporosis - Plant-based estrogen prevents osteoporosis better than estrogen from animal sources, according to a University of California study. Researchers reported that the plant hormone, known as esterified estrogen, given at half the dose of animal-based estrogen (from Premarin, derived from the urine of pregnant horses) was as effective in preventing bone loss and resulted in fewer side effects and was safer. The plant hormone did not thicken the lining of the uterine that precedes endometrial cancer, reduced blood levels of "bad" cholesterol and raised levels of "good" cholesterol, and increased bone density at several different sites, including the lower spine. The plant-based estrogen has not yet been approved by the FDA but is under review.

In The Book of Macrobiotics, educator Michio Kushi explains that from an evolutionary perspective whole grains are humanity’s principal food and contributed to our species’ unique intellectual and cultural development, including upright posture.
“Nature is continually transforming one species into another. A great food chain extends from bacteria and enzymes to sea invertebrates and vertebrates, amphibians, reptiles, birds, mammals, and human beings. Complementary to this line of animal evolution is a line of plant development ranging from bacteria and enzymes to sea moss and sea vegetables, primitive land vegetables, ancient vegetables, modern vegetables, fruits and nuts, and whole cereal grains.
“Whole grains evolved parallel with human beings and therefore should form the major portion of our diet, just as nuts and fruits developed with chimpanzees and apes and formed the staple of their diet and as giant ferns and other primitive plant life evolved in an earlier epoch in conjunction with the dinosaurs. The remainder of our food as human beings may be selected from earlier evolutionary varieties of plants and animals, including land and sea vegetables, fresh fruit, seeds and nuts, fish and seafood, and soup containing fermented enzymes and bacteria represented the most primordial form of life in the ancient sea.”
In selecting supplemental food of animal quality, species that are more primordial are preferable to those that are more recent, Kushi asserts. Thus fish and seafood are preferable to chicken or turkey, and chicken and turkey are preferable to beef and pork. If animal food is eaten regularly, water animals are preferable to land animals, especially mammals, because they are the most further away from us in evolutionary development.
“In the course of evolution, the period of water life, approximately 2.8 billion years compared with the period of land life, approximately 0.4 billion years, produces a spirallic ratio of 7:1. Since human beings are the most recent species to develop upon the land, the composition of our food should be reversed—generally seven parts land quality and one part water quality. If we eat animal food, preferably fish and seafood, this suggests that the ratio of vegetable food to animal food also be in a ratio of 7:1.”
In support of this theory, Kushi points to the structure of the human teeth. The 32 teeth include 20 molars and premolars for grinding grains, legumes, and seeds; 8 incisors for cutting vegetables, and 4 canines for tearing animal and seafood. Expressed as a ratio of teeth designed for grain use, vegetable use, and animal use, the proportion comes to 5:2:1; and of all vegetable quality to animal quality, 7:1.
Similarly, Kushi contends, we consume nutrients on average in a 7:1 ratio in temperate regions (5:1 in colder, northern latitudes and 10:1 in the tropics). Thus, we take in approximately seven times more protein than minerals, seven times more carbohydrate than protein, seven times more water and other liquid than carbohydrate, and seven times for oxygen and air than liquid.
The traditional way of eating, centered on grains and vegetables, represents a harmonious balance of these nutrients. For example, 100 grams of brown rice, millet, and other whole grains contain on average 1-2 grams of minerals, 7-10 grams of protein, and 60-75 grams of carbohydrates. In contrast, hamburger and beef contains less than 1 gram of minerals, 17 grams of protein, and 0 grams of carbohydrate, while sugar (with which they are customarily balanced in the modern diet) contain a trace of minerals, 0 protein, and 99.5 percent carbohydrate.
The standard macrobiotic diet—including 50-60 percent whole cereal grains, 25-30 percent vegetables, 5-10 percent beans and sea vegetables, 5 percent soup (especially enzyme-rich) miso soup, and small, occasional consumption of fish and seafood, fruit, seeds and nuts—contains a harmonious balance of nutrients and recapitulates the whole course of biological evolution on the planet.

An active life, including physical exercise, promotes health and well-being. Proper exercise allows the body to utilize nutrients and food energy more efficiently. The synergistic effects of diet and exercise, as well as other lifestyle factors, are contributing to a better understanding of human physiology and development. See Vegetarians.

• Fresh Foods Promote Exercise - In a study of adolescent behavior, British researchers reported that smoking among high school students was associated with lower levels of exercise, consumption of less fresh vegetables and fruits, and greater consumption of fatty foods. In addition, consumption of fresh foods was found to be positively correlated with exercise.

• Diet Enhances the Benefits of Exercise and Together Lower Heart Disease Risk - In a study of the benefits of exercise compared to exercise plus diet, researchers at Lackland Air Force Base in Texas set up a randomized case control study of 32 men and women in the Air Force. Half the group received individual dietary counseling using the Food Guide Pyramid as a tool, and both groups engaged in an exercise training program. This group received an average of 23 percent of its calories from fat compared to 39 percent in the control group eating in the usual way. The low-fat group had reduction in body mass index, total cholesterol, and LDL levels, which are all associated with lower cardiovascular risk, while there was no improvement in the exercise only group. Meanwhile, the oxygen intake of the diet-and-exercise group improved to 38 percent compared to 14 percent for the control group. “Dietary modification in accordance with the Food Guide Pyramid and the U.S. Dietary Guidelines results in significant reductions in known cardiovascular risk factors and improves the response to exercise training,” the medical researchers concluded.

• Diet and Baseball - In 1983, a Japanese professional baseball team climbed from last to first place by switching to a macrobiotic diet. After taking over the last place Seibu Lions in October, 1981, manager Tatsuro Hirooka initiated a dietary experiment. Restricting the players’ intake of meat, sugar, and white rice, he encouraged them to eat brown rice, tofu, vegetables, and soybean products. He told the players that animal food increases an athlete’s susceptibility to injuries. Conversely, natural foods, they were told, protect the body from sprains and dislocations and keep the mind clear and focused. During the 1982 season, the Lions were ridiculed by their
archrivals, the Nippon Ham-Fighters, a team sponsored by a major meat company. However, the Lions defeated the Ham-Fighters for the Pacific League crown and continued to the Japan World Series and beat the Chunichi Dragons. The Lions won the championship again the following year as well.

•  High-Fat Diet Weakens Physical Endurance - “All of the great feats of physical endurance in history have been accomplished by men who from infancy consumed a diet containing very little saturated or unsaturated fat,” according to noted nutritional researcher Roy Laver Swank, M.D. In a review of dietary changes over the 20th century, Swank, a pioneer in the dietary treatment of multiple sclerosis, cited the accomplishments of the ancients who consumed primarily whole grains, vegetables, and fruits. These include the building of the pyramids in Egypt and middle Africa and the building of the Great Wall of China. “No physical feats to compare with these have been accomplished by people raised on high-fat diets,” he pointed out.
Tracing the increase in fat consumption over the last one hundred years and rise of the modern diet high in synthetic foods, Swank warns that a new wave of nutritional-deficiency diseases may emerge characterized by general weakness and fatigue, irregularities during pregnancy, neurological symptoms, an inability to reproduce, or “abnormalities that develop in offspring after many years of consumption of an incomplete dietary regime.”

• Vegetarians Stronger Than Meat Eaters - In New Haven, Connecticut, Irving Fisher devised tests to measure diet and endurance of Yale athletes eating animal food, vegetarian athletes (from the Battle Creek Sanitarium in Michigan), and vegetarians who were sedentary. The tests included holding the arms outstretched as long as possible, deep knee bends until exhaustion, and repeated leg raises. The vegetarians excelled in all three tests, and the sedentary vegetarians generally exhibited stronger endurance than the athletic meat-eaters.
“The results of the comparisons . . . would indicate that the users of [low-protein] and the non-flesh dietaries have far greater endurance than those who are accustomed to the ordinary American diet,”  Fisher concluded.

• Whole Foods Diet Leads to Greater Endurance - In tests with stationary bicycle to measure energy output, Danish researchers put nine men on a mixed meat and vegetable diet. After three days, the average time pedaled was 1 hour and 54 minutes. On a high-protein diet rich in milk, meat, and eggs, the average time pedaled after three days was 57 minutes. When put on a diet of whole grain cereals, bread, vegetables, and fruit, their mean endurance increased to 2 hours 47 minutes.
