Michael T. Murray and Michael R. Lyon See book keywords and concepts | Food companies and the fast-food industry have used marketing as well as the science of food technology to trigger wanton gluttony in a way that is eerily similar to the methods the tobacco companies employed to develop more addictive cigarettes. The food industry, through lobbying, coercion, greed, and advertising, has influenced us to make dietary choices that fatten us up and harm our health. | | Over the past fifty years, unrivaled changes in food technology, transportation, and agriculture have created an unprecedented increase in the availability of food throughout the world. Because of this, obesity now outranks malnutrition even in most developing countries. According to the World Health Organization (WHO), out of the worlds six billion people, one billion are overweight, compared to 800 million who are undernourished. Even Africa, a continent usually synonymous with hunger, is falling prey to obesity. More than 33. | Lester A. Mitscher and Victoria Toews See book keywords and concepts | Department of Food Science and the Center for Advanced food technology at Rutgers University, recently compared the free-radical-fighting ability of twelve different teas, including several varieties of green, oolong, and black teas. The results were consistent with those from other studies: Dr. Ho found that green tea had the highest yields of polyphenols—particularly for EGCG. Oolong tea was in the middle, and black tea (as a result of its auto-oxidation process) had the lowest polyphenol yield.12
Is the body able to absorb and use the high levels of polyphenols that green tea contains? | Andreas Moritz See book keywords and concepts | Light Fats" and their "Amazing" Effects
Take for instance "light-butter" or half-fat butter, which has been heralded as one of the greatest "achievements" of food technology so far. In this high-tech product, at least half of the fat content of butter is replaced with water. It tastes like butter, it spreads like butter and it melts like butter in the mouth, but in reality it is mostly water. To turn water into butter, you have to mix it with a thickening agent like gelatin, an emulsifier that permits mixing fat with water, and then add artificial coloring, aromas, and preservatives. | Abram Hoffer, PhD, MD, FRCP(C) and Dr. Jonathan Prousjy, DPHE, DSC, ND, FRSH See book keywords and concepts | The balance was destroyed from foods after the introduction of food technology, especially its development over the past 50 years. Until the dawn of agriculture, we did not have to use our intellect to eat well. Our main problem was to obtain enough food. What was available was nutritious. We suffered food shortages and often starvation, and as we moved to colder climates began to suffer from annual epidemics of scurvy. Fruits and fresh vegetation were not available in those times. Today, we have too much food. | Carlo Petrini See book keywords and concepts | The combination of new needs and of new discoveries in the field of food technology made possible a great expansion of the food industry, but it later turned out that the use of chemistry had been too indiscriminate, resulting in food scandals, new diseases, and the impoverishment of our diet in nutritional value and taste. | | There has been a growing predominance of industrial food technology over more traditional methods. Such methods, often dismissed because they were part of everyone's normal stock of cultural knowledge and were deemed unworthy of scientific attention, have faded almost completely away because others produce our food for us. For many today, cooking has become chiefly a matter of heating up something precooked and frozen.
The predominance of technology can be understood if we consider the current academic status of gastronomy compared to that which is accorded to the food technologies. | T. Colin Campbell, Ph.D. and Thomas M. Campbell II See book keywords and concepts | Overall, we are as carnivorous now as we were thirty years ago, but we are able to selectively lower our fat intake if we so desire, due to the wonders of food technology.
To illustrate, we need only to look at two typical American meals.14,15 Meal #1 is served in a health-conscious home, where the main grocery shopper in the family reads the nutrition labels on every food item he or she buys. The result: a low-fat dining experience.
Meal #2 is served in a home where the standard American fare is everyone's favorite. When they cook at home, they make the meal "rich. | Abram Hoffer, PhD, MD, FRCP(C) and Dr. Jonathan Prousjy, DPHE, DSC, ND, FRSH See book keywords and concepts | Before the development of food technology, not counting the introduction of fire and cooking, we only needed to know what foods were safe and what ones would make us sick or kill us. This information was developed by personal experiences passed on by example and instruction to our offspring. We did not have to depend upon reading and teaching.
Fortunately, we did have good instincts based upon our sense of taste, smell, and touch. These are the senses that guide animals in their selection
12 of food. Plant or animal food that did not taste good was avoided. | Carlo Petrini See book keywords and concepts | In the university world, gastronomy has never been represented except in its more folk-loristic forms, or at most as the subject of anthropological and ethnographical research, whereas the food technology used by industry boasts high-powered specialists who teach at universities all over the world.
In reality, the fund of traditional knowledge on the subject of food processing—the set of simple acts of everyday preparation—is an extremely rich and valuable heritage. | Abram Hoffer, PhD, MD, FRCP(C) and Dr. Jonathan Prousjy, DPHE, DSC, ND, FRSH See book keywords and concepts | The major problem with modern food technology is that it has destroyed our senses as good indicators for what foods are safe and nutritious and for what foods are not.
Raw, Cooked, Refined, and Processed Foods
Our modern high-tech diets have been developing over the past 10,000 years, but the pace of change has accelerated sharply over the past 50 years. We have the same genetic structure our ancestors had 10,000 years ago, but the food supply today is totally different from what it was then. | | There was no change in food technology except for storage. It was now possible to store grain for several years. In the bible, Joseph advised the Pharaoh to store a 7-year supply of grain in preparation for the 7-year drought he predicted.
Agriculture forced a change in social habits, from a wandering, nomadic existence to the development of large cities. Territorial needs were changed from sparsely occupied areas with few interactions with others to huge, over-crowded, over-concentrated areas we know as modern cities. | | Grinding and separating cereal components is the basis for much of our present food technology.
Grinding was an important discovery because it made it possible to digest foods that formerly could not be digested. Sifting out the most nutritious portion of the grain to create while flour became fashionable for the wealthier classes. The poor, slaves, and peasants had to be content with whole-meal grain. They were, of course, lucky and must have been healthier than their masters and superiors. | Phyllis A. Balch, CNC See book keywords and concepts | A poll of 37,000 Americans conducted by food technology found that half of them were deficient in vitamin Bg (pyridoxine), 42 percent did not consume sufficient amounts of calcium, 39 percent had an insufficient iron intake, and 25 to 39 percent did not obtain enough vitamin C. Additional research has shown that a vitamin deficiency may not affect the whole body, but only specific cells. For example, those who smoke may suffer from a vitamin C deficiency, but only in the lung area. | Abram Hoffer, PhD, MD, FRCP(C) and Dr. Jonathan Prousjy, DPHE, DSC, ND, FRSH See book keywords and concepts | Tomorrow is our responsibility
Modern food technology has become food chemistry. We know a good deal about the chemical structure of food, but in the process of developing the chemistry of food, we have neglected to study the physiology of food. There is thus an almost total imbalance between our needs and what we eat. It is almost as odd as feeding lions only on grass. Our needs are the type of whole foods to which our ancestors had adapted 10,000 years ago. | Kaayla T. Daniel, PhD, CCN See book keywords and concepts | That's primarily due to food technology specialists and their lavish use of sugar and other sweeteners, salt, artificial flavorings, colorings, preservatives and MSG. It also hasn't hurt that newer refining techniques yield blander and purer soy proteins than the "beany," hard-to-cover-up flavors of the past. Cargill even bills its new soy protein isolate as "inconspicuously good. | Glenn W. Geelhoed, M.D. and Jean Barilla, M.S.

Raw Or Processed?
The best honey is raw, not processed. Raw honey is loaded with bee pollen, enzymes and nutrients, all of which are destroyed when it is processed with high heat and filtration. In fact, once honey is processed, all you're really left with is the sugars. | Patrick Quillin, PhD,RD,CNS See book keywords and concepts | Tomomatsu, H, food technology, p.61, Oct. 1994

In the United States, the FDA requires irradiated foods to be labeled "treated with (or by) radiation" and to display the international symbol of irradiation—the radura—printed in green. As shown in figure 9, the radura symbol resembles the logo of the Environmental Protection Agency (EPA) and is meant to reassure the public that irradiated foods are ecologically correct, or "green. | | Buchanan RL, Doyle MP. food technology ij97;5i(io):69-76.
""Bringing a food to 15 5°F is sufficient to kill these bacteria; recommended cooking temperatures provide a 5°F margin of safety. Pasteurization brings liquids to scalding temperatures (about i40°F) for short times; this process desrroys mosr bacteria and delays the growth of rhose that survive.

Side effects: Only to be expected with overdoses, which lead to gastrointestinal irritations with stomach pains, diarrhea, and similar complaints. Quillaja extracts have been shown to be non-toxic in test animals (rats, mice) [12], also in long-term experiments wherein rats were fed 0.7 g extract per kg daily for a period of 108 weeks.

In addition, manufacturers fortify many foods with vitamins and minerals. "Our food technology has really helped make these diseases a thing of the past," says Jack M.

Of course, the types of parsnips you buy in the store have much lower levels of coumarins than their wild kin. (Like people who sweat when they're upset, parsnips release more coumarins when the climate and conditions are contentious.) You'd have to eat an awful lot of domesticated parsnips—say, a 2-pound bunch in one day or even more, Dr. Rosen speculates—before you'd have trouble.
The Acid Test
Along with carrots and celery, parsnips are members of the umbelliferae family. | | Center for Advanced food technology at Cook College of Rutgers University, in New Brunswick, New Jersey. "But we need more research before we know exactly how it works or how much plantain is needed for the effect."
More Filling, Fewer Calories
Although they're not one of the best food sources of fiber, plantains have the distinction of being among the top foods to offer a gram of fiber for the fewest calories. To get about 1 gram of fiber, all you need is Mo cup of boiled, mashed plantain, for the small price of 58 skinny calories. | | In addition, manufacturers fortify many foods with vitamins and minerals. "Our food technology has really helped make these diseases a thing of the past," says Jack M. Cooperman, Ph.D., clinical professor of community and preventive medicine at New York Medical College in Valhalla.
But even though serious deficiency diseases are rare in this country, they still occur. People who are ill with digestive disorders or other conditions may not get all the nutrients they need. People who abuse alcohol are particularly prone to deficiency diseases, as are those who live in poverty. | Carlton Fredericks, Ph.D. See book keywords and concepts | | It is a striking example of the blindness of food technology to the nutritional needs of the public it exploits.
Lecithin
Known in nutrition as a phosphatide, this natural factor in oils (which is also manufactured in the body) is an antioxidant which is removed from polyunsaturated fats. In the body, lecithin has a variety of critical functions, one of which involves fat transport and control of cholesterol. | Isadore Rosenfeld, M.D. See book keywords and concepts | According to the Institute of Food Technologists in the July 1991 issue of its journal, food technology, there are essentially six different types of vegetarianism. The basic diet of all six consists of plant foods. Here are the variations:
1. Semivegetarian: dairy foods, eggs, chicken, and fish, but no other animal flesh. This is probably the most popular kind of vegetarianism.
2. Pesco-vegetarian: dairy foods, eggs, and fish, but no poultry or other animal flesh.
3. Lacto-ovo-vegetarian: dairy foods and eggs only, but no animal (and that means fish too) flesh.

Aspartame under Fire
The artificial sweetener aspartame (NutraSweet) is a miracle of food technology. Made from two amino acids, it is 200 times sweeter than sugar, yet delivers almost no calories.
Over the years, however, it has come under fire because of persistent speculation that it may contribute to serious problems such as seizures and attention deficit disorder. While research has shown that aspartame doesn't play a role in either of these conditions, it isn't entirely without risk, at least for a small number of people. | | Center for Advanced food technology at Cook College, Rutgers University, in New Brunswick, New Jersey.
In addition, celery contains compounds called phenolic acids, which block the action of hormonelike substances called prostaglandins. Some prostaglandins are thought to encourage the growth of tumor cells, says Dr. Rosen.
Leave on the leaves. While celery stalks are certainly a healthful snack, it's the leaves that contain the most potassium, vitamin C, and calcium.
Eat it the way you like it. |
