CHILDREN’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.

• 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 cancer

BREAST CANCER
Breast cancer has reached epidemic proportions in modern society, affecting 1 in 8 women. Breast cancer rates are substantially lower in countries where plant-centered diets are eaten. The protective effects of miso, tofu, and other soy products high in phytoestrogens and isoflavones are being intensively studied around the world. See Carrots, Dairy, Estrogen, Isoflavones, Menopause, Menstrual Disorders, Miso, Phytoestrogens, Sea Vegetables, Soy Foods, Tofu, Tempeh, Vegetables, Vegetarian Diet, Vitamin D, War-Restricted Diet, Women’s Health.

• Macrobiotic Diet Lessens Breast Cancer Risk - Macrobiotic and vegetarian women are less likely to develop breast cancer, researchers at New England Medical Center in Boston reported. The scientists found that macrobiotic and vegetarian women process estrogen differently from other women and eliminate it more quickly from their body. The study involved 45 pre- and postmenopausal women, about half of whom were macrobiotic and vegetarian and half nonvegetarian.
The women consumed about the same number of total calories. Although the vegetarian women took in only one third as much animal protein and animal fat, they excreted two to three times as much estrogen. High levels of estrogen have been associated with the development of breast cancer. “The difference in estrogen metabolism may explain the lower incidence of breast cancer in vegetarian women,” the study concluded.

• Miso Retards Tumors - In laboratory experiments, Japanese researchers reported that chemically-induced breast tumors in rats could be significantly decreased by feeding the animals a diet consisting of 10 percent miso.

• Kombu Decreases Risk of Breast Cancer - In an experiment at the Harvard School of Public Health, laboratory animals fed a control diet with 5 percent Laminaria (kombu), a brown sea vegetable, developed induced mammary cancer later than animals not fed seaweed.
“Seaweed has shown consistent antitumor activity in several in vivo animal tests,” the researchers concluded. “In extrapolating these results to the Japanese population, seaweed may be an important factor in explaining the low rates of certain cancers in Japan. Breast cancer shows a three-fold-lower rate among premenopausal Japanese women and a nine-fold-lower rate among postmenopausal women in Japan than reported for women in the United States. Since low levels of exposure to some toxic substances have been shown to be carcinogenic, then it may be that low levels of daily intake of food with antitumor properties may reduce cancer incidence.”

• Tofu and Miso Protect Against Breast Cancer - In a study of the effects of soy products on female hormones, Japanese scientists reported that consumption of miso and tofu reduced production of estradiol in 50 healthy premenopausal women. “Our results suggest that the consumption of soy products lowers the risk of developing breast cancer risk modifying estrogen metabolism,” the researchers concluded.

• Asian Diet Helps Heal - A diet high in soy foods, vegetables, and fish oil may reduce the risk of breast cancer, according to a study conducted by the Jonsson Cancer Center at the University of California at Los Angeles. Dr. John Glaspy put 25 American women in remission from breast cancer on an Asian-style diet and reported that in three months on the diet the ratio of omega-3 in the women’s blood rose fivefold. The omega-3 to omega-6 ratio in breast fat is considered a major indicator of risk for this disease. Source: D. Bagga et al., “Dietary Modulation of Omega-3/Omega-6 Polyunsaturated Fatty Acid Ratios in Patients with Breast Cancer,” Journal of the National Cancer Institute 89(15):1123-31, 1997.

• Diet Lowers Risk for Hispanics - Hispanic women in the U.S. have the lowest mortality rate from breast cancer of all ethnic groups. University of Texas researchers reported that a study of 22 Hispanic women in the Houston area showed their mean intake of dietary fiber from grains, breads, beans, and vegetables was higher than other groups. “This may help explain the lower incidence of breast cancer among some Hispanic populations,” the study concluded.
Source: “Dietary Fiber, Hispanics, and Breast Cancer Risk?” Annals of the New York Academy of Science 837:524-36, 1997.

• Risks of Tamoxifen - Tamoxifen, a synthetic hormone that blocks estrogen, has been promoted for reducing the risk of breast cancer. However, it increases the risk of uterine cancer and blood clots. In a federal study, women who took tamoxifen had 45 percent fewer cases of breast cancer than controls, but over twice as much uterine cancer, nearly three times as many blood clots in the lungs, and 50 percent more blood clots in major veins.
For women age 50 or older, for every one thousand women treated with tamoxifen for five years, the drug might prevent 17 cases of invasive breast cancer, while causing 12 cases of endometrial cancer and 10 serious blood clots.

ARTHRITIS
Arthritis, a painful bone and joint disease, affects millions of people. Major forms include osteoarthritis, the painful hardening of bones and joints in the hands or spine, which affects primarily older people, especially men. Rheumatoid arthritis, involving the inflammation and swelling of the joints, especially in the hands and feet, appears primarily in women aged 25 to 50. A balanced diet has benefited some people with arthritis. Excessive animal food and salt appear to be connected with osteoarthritis, while potatoes, tomatoes, and other nightshade plants have been associated with rheumatoid arthritis. See Fibromyalgia, Fish, Lupus, Nightshades, Sesame, Vegetarian Diet.

• Macrobiotic Approach - The macrobiotic approach to arthritis, including a classification of the different types of arthritis, dietary guidelines, home cares, and case histories, is included in several books devoted to this subject. Some arthritis is believed to be caused by strong animal food intake, especially chicken and eggs, while another type is associated with tropical fruits and vegetables, especially nightshades.

• Low-Fat Diet Relieves Rheumatoid Arthritis - Fat-free diets have produced complete remissions in six patients with rheumatoid arthritis. Doc- tors at Wayne State University in Detroit reported that when a low-calorie, low-fat diet in which chicken, cheese, safflower oil, beef, and coconut oil were eliminated, stiffness and swelling of joints disappeared within days. Patients remained symptom free for up to fourteen months, only to experience short-term recurrences within usually 24 to 48 hours of eating foods which were high in fat. “We conclude that dietary fats in amounts normally eaten in the American diet cause the inflammatory joint changes seen in rheumatoid arthritis.”

• High-Fat, High- Sucrose Diet Contributes to Arthritis - In laboratory experiments, rats fed a diet high in fat and sucrose developed abnormal stiffness, reduced energy, and other adverse morphological and structural changes.

• Vegan Diet Helps Arthritis Patients - In a study of 43 patients with rheumatoid arthritis, researchers reported that those assigned to a vegan diet rich in lactobacilli had changes in fecal microbial flora associated with improvement in rheumatoid arthritis activity.

• Arthritic Patients Improve on a Vegetarian Diet - In a case control study, rheumatoid arthritis patients assigned to a vegetarian diet had a significant decrease in platelet count, leukocyte count, calprotectin, total IgG, IgM rheumatoid factor, and other biochemical and immunological variables compared to those assigned to an omnivore diet. The researchers concluded that “dietary treatment can reduce the disease activity in some patients with rheumatoid arthritis.”

Appendicitis

APPENDICITIS
Appendicitis, the acute inflammation of the appendix, tends to strike younger people, aged 10 to 30. It commonly occurs on holidays or special occasions following a large meal. It is the most common cause of abdominal surgery in the U.S. A ruptured appendix is potentially life-threatening.

• Operations Higher Among Meat Eaters - In a study comparing the rates of appendectomies among 11,000 vegetarians and nonvegetarians, British researchers reported that the percentage who had this procedure was higher among lifelong meat eaters (10.7 percent). In contrast, lifelong vegetarians had a 7.8 percent appendectomy rate, while those who had stopped eating meat had 8 percent. “The results suggest that people who do not eat meat have a 50 percent lower risk of requiring an emergency appendectomy than those who do,” the scientists concluded.
