Wednesday, April 15th, 2009Macrobiotic nutrition
Today very popular idea MACROBIOTIC comes from Greek words, that means “big, long life - longevity”. It’s needed to mention that macrobiotic does mean not only the way of nutrition, but also whole philosophical system connected with it, that from one part comes from religiously - philosophical zen-buddhism.
Zen doesn’t abjure life, it only propagate full merging to the life - food don’t have to degrade man, to man be its slave. Assure more deeper possibility of health by following the right path. That’s why with obesity is good to choose at least some methods from macrobiotic diet, compare them with energetical options of reduction diet.
Macrobiotic diet has more levels, altogether ten, from the lowest, that is the most similar to our racional nutrition, to the highest (that is not always recommended), where is nutrition composed solely from whole grain products. A kind of founder of modern macrobiotic doctrine is Japanese George Oshawa (1893 - 1966), he asserted, that there exist no illnes (so also no malignant tumours), that couldn’t be healed by appropriate use of natural foodstuffs. Convincing evidence about this are not yet there, even if with this nutrition you can preventively strike against emergance of malignant tumours (for example large intestine).
Lower levels of macrobiotic diet contain still relatively varied, not monotonous nutrition, higher levels are already stereotypic, one-sided, the higher have to eventually result into deficiency disease, deficiency of many basic nutrients (full-valuable proteins, essentials fatty acids, some vitamins, trace elements, salts). The food in the scope of these highest levels actually cease to be enjoyment.
The base of ideology of macrobiotic nutrition is assertion, that in foods exist mysterious energies, principles Yin (female) and Yang (man), whose mutual ratio gives the food their nutritive value. The best ratio of yin and yang has supposedly whole grain. Yin is dominant in potatoes, tomatoes, spinach, mushrooms, butter, bananas, honey, champagne etc. Whilst yang is in cereals, carrot, apple, goat cheese (not so in goat milk) etc. On the practical feature is basic requirement of macrobiotic nutrition, natural foods, non refined, not chemicaly manufactured, without fertilizers, pesticides and herbicides, which is nearly inaccessible. Whole grains should be in their natural, non refined, so called integral form - for example brown rice, wheat.
Sort of middle form of macrobiotic diet is yet acceptable, it consist of 50% whole grains (rice, wheat, millet, corn, rye, barley), from 40% legumes, vegetables (that grows on the ground, sea - some seaweeds), soups from them, 10% prducts of animal origin (only white meats, fish, poultry, turkey, eggs and milk only a little), fruits minimaly, no sweet fares. The highest level of macrobiotic nutrition does mean 90% of whole grains and 10% vegetables.

Children’s health
Wednesday, April 15th, 2009CHILDREN’S HEALTH
An increasing number of parents, teachers, and community organizations are concerned with the effects of the modern way of eating on children. Medical studies have begun to link hyperactivity, learning disabilities, and other syndromes with improper food. See Attention-Deficit Disorder Breast-feeding, Chocolate, Cholesterol, Dai-ry, Food Guide Pyramid, Heart Disease, Japanese Diet, Macrobiotics, Obesity, Pesticides, Prenatal Nutrition, Rice, Sea Vegetables.
• Processed Foods - In testimony before the Senate Select Committee on Nutrition and Human Needs over 20 years ago, Dr. Carolyn Brown, director of a school for learning disabled children in Berkeley, Calif., pointed to the social effects of changes in diet and lifestyle since World War II:
“Let us look for a moment at a few interesting health and social statistics. The members of this committee know well the evidence of the increase in synthetic foods, and other nutritional changes. . . . What do we know about what has happened to the children that grew up during these twenty-five years? We know that there was a sixfold increase in arrests of children under 15 suspected of murder, non-negligent manslaughter, aggravated assault, and rape. The factor increase was three for 15- to 17-year-olds, two for 18- to 25-year-olds. We know that ‘accidents’ resulting in death rose dramatically among the young, that divorce rates have continued to increase, that suicides have been rising among young people in comparison to the rest of the population. And we know that there has been an unprecedented 14-year decline in the scores of our most gifted children on the Scholastic Aptitude Tests. . . During the eight years from 1958 to 1966, children under seventeen with chronic health problems increased from 18.8 to 24.6 percent. Those from 17 to 24 showed an increase from 39 to 44.4 percent. . . .
“I would like to ask you senators, when we know what has happened during the past 25 years in terms of the increase in non-nutritous foods, radiation exposure, television exposure, and exposure to environmental toxins—and when we know that children born during that period show a dramatic increase in juvenile delinquency, arrest for serious crimes, chronic health problems, and low scores on Scholastic Aptitude Tests—is it not at least a fair question whether we are exposing our children on the whole to an increasingly powerful set of environmental stressors that is producing a broad range of forms of biosocial decline?”

• Learning Disabilities - In a study of learning disabilities in children, researchers reported that diets high in refined carbohydrates raised cadmium levels, which have been associated with reduced cognitive functioning. Intellectual ability was also negatively correlated with refined food independent of cadmium, age, race, sex, and socioeconomic status.
Source: M.L. Lester et al., “Refined Carbohydrate Intake, Hair Cadmium Levels and Cognitive Functioning in Children,” Journal of Nutrition & Behavior 1:3-13, 1982.
• Macrobiotic vs. Conventional Diet - A British nutritionist found that a macrobiotic day-care center in London not only “supported normal growth” in nursery school children but also could be used as a model to implement national dietary guidelines. Comparing the nutritional adequacy of macrobiotic meals provided preschool children by the Community Health Foundation with ordinary meals at a nursery in Notting Hill, the investigator found that the macrobiotic food consisting of brown rice and other whole grains, miso soup, vegetables, beans, sea vegetables, and other supplemental foods met current U.K.-R.D.I. dietary, energy, and nutrient standards and that the children’s anthropometric measurements including weight, height, and skinfold thicknesses were normal.
In contrast, the ordinary nursery school diet was high in dairy food, lard, and other saturated fats that have been associated with the development of atherosclerosis beginning in childhood. “The diet composition of children in Group I [standard nursery] could be made more desirable by a reduction in the amount of full-cream milk and meat and an increase in the amount of cereal foods . . .,” the researcher concluded. “The total diet of Group II [macrobiotic nursery] met the U.S. Dietary Goals for fat, sugar, and carbohydrate content, although the home diets of the children were similar to that of the general population. This illustrates the power and potential of nursery meals to contribute to the adoption of a nutritionally sound and beneficial national diet.”

• Whole Grain Diet Improves Children with Learning Disabilities - When put on a diet centered on whole grains, complex carbohydrates, and unprocessed foods, 16 children with learning and behavioral problems showed significant improvements in behavior, learning, and intelligence compared to 16 controls over a 22-week trial period. Further, cadmium and iron levels, which have been linked to learning disabilities, fell 28 and 49 percent respectively.

• Macrobiotic Approach In Raising Health Kids - Michio and Aveline Kushi offer a macrobiotic approach to bringing up children, incorporating insights from traditional Far Eastern medicine and philosophy. Topics covered include family health and happiness; how children develop; diet and daily care; and keeping children happy. Much of the book is devoted to using diet to treat common conditions including simple fever, headaches, stom-ach ache, colds and flu, earaches, sore throats and tonsillitis, measles, roseola, mumps, chicken pox, rickets, bed-wetting and sleeping difficulties, whooping cough, pinworms, skin disorders, hyperactivity and behavioral problems, accidents, emergencies, and first aid. The book also includes recipes, a home care guide, and palm healing for children.

• Normal Development Among Macrobiotic and Vegetarian Children - In a study of vegetarian preschool children, researchers at New England Medical Center Hospital in Boston found that the growth of macrobiotic youngsters did not significantly differ from those of non-macro-biotics before age two. After age two, macrobiotic children tended to put on weight more quickly than the children brought up on yoga diets, Seventh-Day Adventist diets, or other vegetarian regimes. Nearly all the children had been breast-fed, and it was found that macrobiotic children who had been weaned did not differ in caloric intake from nonmacrobiotics.

• Low-Fat Diet Benefits Babies - Babies 7 to 13 months benefit from a diet low in saturated fat. In a case control study in Finland, researchers found that healthy infants who ate more polyunsaturated fat and less saturated fat than controls had 6 to 8 percent lower cholesterol in their blood. Both groups developed at a similar rate. The Finnish researchers noted that in earlier studies, the arteries of babies showed signs of early atherosclerosis in modern society and that exposure to a healthful diet “at the earliest possible age” would more likely adhere in future years.

• Heart Disease in Teens and Young Adults - By their teens, most Americans have fatty deposits in their blood vessels, according to the largest autopsy study conducted on adolescents and young adults. The results show that most youths are at risk for heart disease, said Dr. William H. Dietz, director of clinical nutrition at New England Medical Center. The study of 1532 autopsies of young people who died from trauma found that half had coronary arteries showing evidence of early heart disease by age 19, while all 100 percent had fatty patches in the aorta, the main artery leading from the heart. “Aortic fatty streaks are universal by age 15 and increase rapidly in extent during the following decade,” the researchers concluded. The scientists further reported that the fatty streaks had progressed to tough, fibrous deposits that narrowed coronary arteries in the vast majority of both men and women by their early thirties. Interestingly, young females aged 15 to 19 had slightly higher fat deposits in the right coronary artery than young males. However, by the mid-twenties and early thirties males surpassed females.

Breast feeding
Wednesday, April 15th, 2009BREAST-FEEDING
Mother’s milk has sustained the human species for countless generations. Breast milk is high in substances that confer natural immunity on the developing infant and protect against infection and disease. Breast-feeding also confers protection for the mother. See AIDS, Chocolate, Microwave, Mochi, Pesticides, Prenatal Nutrition, Rice, Sea Vegetables, Skin Problems, Vegetarian Diet.
• Breast-feeding Reduces Ear Infections - Breast-feeding can drastically reduce the number of ear infections in babies for the first four months, according to a University of Arizona study.
“The longer you can breast-feed exclusively, the fewer the episodes of ear infection, but four months is the minimum for significant protection,” noted Dr. Burris Duncan, who directed the study. His findings showed that 56 percent of babies who nursed for four months or more had infections compared to 68 percent of babies who were not nursed.
Source: B. Duncan, “Exclusive Breast-feeding for at Least 4 Months Protects Against Otitis Media,” Pedriatrics; 91:867-72, 1993.
• Breast-feeding Lowers Lymphoma Risk - Breast-feeding can reduce the risk of certain cancers for both mother and child. Researchers from the National Institute of Child Health and Human Development in Bethesda, Md., found that infants breast-fed more than 6 months had a lower risk of developing cancer in childhood, especially lymphomas. In this study, children who were formula-fed or breast-fed for less than 6 months had approximately twice the risk of getting some childhood cancers by age 15 as those breast-fed for longer than 6 months. They also had five times the risk of getting lymphoma. “Mother’s milk contains substantial antimicrobial benefits for infants, increasing their resistance to many infections and possibly protecting them from many diseases, including lymphomas,” researchers reported.
Source: “Breast-Feeding Linked to Decreased Cancer Risk for Mother, Child,” Journal of the National Cancer Institute 80:1362-63, 1988.
• Breast-feeding Promotes Mental Development - Children born prematurely who were breast-fed scored significantly higher on intelligence tests than those who did not. “Our evidence strongly suggests that human milk might have factors important to brain development,” noted Dr. Alan Lucas, director of the study and head of infant and child nutrition at the Medical Research Council’s Dunn Nutrition Unit in Cambridge, England.
On average, the children given breast milk scored eight points higher on a range of intelligence tests taken when they were eight years old.
Source: A. Lucas et al., “Breast Milk and Subsequent Intelligent Quotient in Children Born Preterm,” Lancet 339:261–64, 1992.
• Breast-feeding Lowers Breast Cancer Risk - In a Chinese medical study, researchers found that the longer the mother nursed, the less at risk she was of breast cancer. Mimi Yu, Associate Professor of Preventive Medicine at the University of Southern California in Los Angeles, studied more than 500 Chinese women with breast cancer in Shanghai and 500 healthy women. The women she studied on an average nursed their various children for a cumulative total of nine years, a common pattern in China. “We believe that long periods of nursing would have the same protective effect for American women,” Yu reported.

• Breast-Fed Children Smarter - Children who are breast-fed as babies are smarter and do better than kids brought up on bottled milk, according to a New Zealand study. In a study of more than one thousand children, researchers found that those who were breast-fed for 8 months or more tested between 35 and 59 percent higher in reading comprehension, mathematical ability, and scholastic ability when they were 10 to 13 years old.
Source: L. J. Horwood and D. M. Fergusson, “Breast-feeding and Later Cognitive and Academic Outcomes,” Pediatrics 101(1):E9, 1998.
• Attention Deficit Disorder Linked to Less Breast-feeding - In a case-control study of diet and attention-deficit hyperactivity disorder, Purdue University researchers reported that children with ADHD were about half as likely to have been breast-fed as controls. The duration of breast-feeding was also significantly longer in ordinary children than those with this behavioral disorder characterized by inattention, impulsivity, and hyperactivity. ADHD children were also found to have lower amounts of specific fatty acids, especially omega-3 fatty acids. These are found in vegetables, fruits, and other plant quality foods, as well as in fish and seafood.
