New Extension Assistant
Kim Werning is a new Extension assistant working with Karen Penner and Betsy Barrett (HRIMD) on a 7-county pilot project involving SRS and extension. Food service sanitation and job skills are combined to improve employment opportunities for Kanwork participants.

Kim has a BS in Business Management from Central College in Pella, Iowa and a MS degree in Hotel, Restaurant, and Institution Management from Iowa State University. She is currently a graduate student at KSU completing her coursework to take the R.D. exam. Kim also is the organist/choir director at a local church.

Her previous work experiences include 7 years of food service management with Marriott Healthcare Services (4 1/4 years), Grinnell College (9 months), and Iowa State University (2 years) and 1 year of retail management with K-Mart. (KW)

What's Up with Fast Food?
Currents trends in the food-service business include globalization, convenience, values and variety. Food service companies are rapidly moving into global markets to expand sales. McDonald's is the largest fast food competitor with $ 7.3 billion in sales last year. McDonald's has 14,000 units in 68 countries and will add a thousand a year for the next few years. Global growth in fast food outlets of many kinds will affect dietary customs around the world.

Consumers are spending more money for food on the go. Food spending away from home exceeded spending for meals prepared at home for the first time last year. Today, one in ten meals is eaten in a car. McDonald's is now building facilities with double drive-through. Twice the car traffic, a walk-up window and no inside seating units are geared for cars alone. Other fast food units on-the-rise include kiosks, carts, mini-restaurants for high-foot traffic areas. Mobile consumers eat at all hours and any place available so food-service is moving to be there, where the people are.

Value is important. Big, basic and value-pricing are important. Examples are products like Pizza Huts Big Foot and Wendy's Big Classic. Advertising increasingly features low prices.

Burgers, Italian and Mexican have become mainstays but new twist on old popular items create new interest and sales opportunity. Boston chicken, roasted on a rotisserie, with all the fixins of mashed potatoes, salads, squash have driven KFC a run for its money. The perception of healthier food has been a successful one. In reality, the fat, salt and sugar content of a typical meal is similar to a traditional fried chicken take-out meal.

Watch for these trends in towns near yours! (KP)

E Coli in 1994
In 1994, there have been 20 reported outbreaks of foodborne illness from E. coli 0157:H7 bacteria, three more than in 1993 according to the Centers for Disease Control. The latest outbreak involved salami. (KP)

Study Documents EFNEP's Positive Impact
A recent study of the impact of USDA's Expanded Foods and Nutrition Education Program (EFNEP) showed the program has a positive impact on food knowledge and behavior. The study conducted by Cornell University also identified other benefits including employment, continued education, community involvement and improved health. EFNEP is a nutrition education program targeted at low income families with children. It is an integral part of the Extension system in every state.

The Cornell study of 50 EFNEP participants assessed 12 food behaviors upon entry, graduation and one year after completing the EFNEP classes. Participants significantly improved ten of the 12 behaviors between entry and graduation. Consumption of most nutrients remained stable from entry to graduation. There was a significant reduction of dietary fat.

Participants reported additional benefits including better family health, employment (the employment rate rose from 24% to 34% between graduation and the one year following), a desire for education, and greater community involvement. (MP)

WIC Celebrates Its 20th Year
Since its inception in 1974 in Kansas, WIC has made great progress in improving the health of women and children. The program has grown statewide, currently reaching nearly 60,000 participants in 105 Kansas counties. Partnerships with other agencies have strengthened programming. For example, for the past year, Kansas WIC and the KSU Extension Service have collaborated on the development of a nutrition education program known as The WIC Kitchen. The program was implemented in seven counties in 1994 and will be expanded to 16 additional counties in 1995.

WIC accomplishments include:

 Women who participated in WIC have fewer premature births. Incidence of premature births decreased 23% among white women with less than a high school education and 15% among African American women with less than a high school education.

 WIC significantly increased the head size of infants whose mothers received WIC foods during pregnancy. Head size often reflects brain growth.

 Children participating in WIC are better immunized and are more likely to have a regular source of medical care.

Every dollar spent for prenatal care in WIC results in up to $4.21 in Medicaid costs saved during the first 60 days after birth. (MP)

Hindmilk for Premature Infants
Low birth weight babies are experiencing greater weight gain as a result of new feeding practices developed at Children's Nutrition Research Center at Baylor College of Medicine. In a study of 15 infants who were eight to 12 weeks premature, there was a significant increase in weight when the infants were fed "hindmilk" (milk produced two to three minutes after the initial flow). The new feeding practice requires expressed milk to be divided into two parts: the foremilk which is collected and frozen for later use and hindmilk which is three to four times higher in fat than the foremilk.

Premature infants cannot suck or swallow well and often must be fed breastmilk in regulated amounts through a tube. Often fat content of the milk varies because it tends to separate from milk and stick to feeding tubes and collection bottles. In the past, infants who failed to gain weight were placed on formula which has a more consistent composition and is homogenized so the fat does not separate. However, because evidence indicates breast milk protects premature infants from potentially life-threatening infections, researchers are exploring ways to utilize breast milk for these at-risk infants.

Suggestions for Inviting Children to Taste New Foods
We know that in order for children to learn to like new foods, they have to taste them first! Often getting them to taste it is no easy task. Many parents and child care providers ask for advise on what they can do. Some suggestions:

The "delicious minimum" is one technique. When the child says, "I don't like carrots" or "I don't want any carrots" the adults responds "You don't like carrots. (This lets the child know that he or she was heard.) Well then you can just have the "delicious minimum". The adult then gives the child a spoon to help him or herself and the child need only take one spoonful. Then the adult says, "If you decide to have more than the delicious minimum, just let me know and we'll pass you the carrots." No effort is made to coerce the child into eating the delicious minimum, but most children go ahead and eat it just because it's there.

The "taste bite" is another method that works with groups of children. When a new food or a food prepared a little differently is served, the adult suggests "Let's do a taste bite." The children all taste at the same time. No attention is drawn to the children who deferred. Usually all of the children will think this is great fun. Various commentaries will often follow. Most children won't automatically give negative comments, even though the common wisdom is that they are naturally afraid of new things.

Another idea is the "no thank you bite". If a child says he or she does not like or want a food, the adult will say "That's fine, just take a no thank you bite." The child is then allowed to serve him or herself a tiny portion, and that is the end of it. Many times the child will taste it, but they are not forced to.

Although these suggestions will often work and the child(ren) will think it is fun, no child should be forced to try the new foods. Adults should respect the children and understand that they have likes and dislikes just as we do. Besides, forcing children to taste new foods does not teach them to like the food, it only teaches them how to please the adult. (PP)

Experts Examine Fat in Diets of Young Children
The amount of fat children need in their diet has been the subject of much controversy over the years. Even today there is not a consensus. At the recent meeting of the American Dietetic Association in Orlando, Florida, this topic was discussed by experts from the United States and Canada.

The United States Government recommends no more than 30 percent of total calories come from fat for both adults and children. They also recommend no more that 10 percent of calories from saturated fat. In Canada, however, no limitation on fat is recommended because such restrictions could stunt growth, according to Canadian nutrition expert Stanley Zlotkin, M.D. Dr. Zlotkin, a professor of pediatrics and nutrition science at the Hospital for Sick Children of the University of Toronto, is concerned about the idea of `good' and `bad' foods, and the increasing incidence of eating disorders. He believes that the more emphasis there is on restricting any food, the more likely adolescents are to become preoccupied with food.

A U.S. expert, Ronald Klienman, M.D., noted the "trickle-done" acceptance of the need to trim fat. The dietary recommendations for adults in this country are pretty well accepted among health care professionals. The question that needs to be raised is whether it makes sense to adopt these guidelines regarding fat to children. (PP)

Iron During Pregnancy
Pregnant women naturally absorb more iron than before they become pregnant. The rate of iron absorption also increases as pregnancy progresses. Expectant mothers absorb nine times more iron during the 36th week of pregnancy than they did during the 12th week. Because of this increased efficiency for iron, most pregnant women do not need supplements. They can enhance their iron absorption further by not drinking coffee or tea with their iron-rich meals. These beverages (both caffeinated or decaffeinated) block the uptake of iron by the body. (PP)

Energy Needs of Infants
Pound for pound, infants burn more calories than children or adults. That's because a larger percentage of infants' body weight is devoted to organs, such as heart, liver, and brain, which have a higher metabolic rate than muscle tissue. Adults, on the other hand, have a larger percentage of body weight devoted to muscle tissue. As a result, energy requirements from birth to adulthood don't increase at the same rate as body weight. The findings come from an ongoing study of the energy infants, children and adults expend while sedentary. Researchers at the Children's Nutrition Research Center at Baylor College of Medicine in Houston and at other centers are collecting data on the amount of energy needed to maintain basal functions, metabolize meals and do minimal physical activity. This gives a more precise basis for estimating daily calorie requirements than basal metabolic rate alone. (PP)

Walking Affects Bone Health at Any Age


A lifelong habit of walking about a mile a day can reduce the risk of osteoporosis in women, whether or not they engage in sports or other physical activities. A year-long study of 238 healthy women past menopause found that those who habitually walked more than 7.5 miles a week had denser bones, particularly in the legs and trunk, than those walking shorter distances. Also, the mile-a-day walkers had slower rates of bone loss in their legs during the study.

Researchers measured bone densities in the women and took detailed histories of their physical activities from age 14. The study was the first to correlate women's bone density with their walking history alone. An earlier study by others found a comparable correlation for all activities on foot to age 50. Osteoporosis results from a long-term loss of bone minerals, which accelerates around the time of menopause, leaving the bones porous and prone to fracture. It also affects men and will increase as a health problem among men as they live longer. (PP)

Dangerous Water Loss In Elderly
For anyone over the age of 65, dehydration (water loss in body tissues) looms as one of the most common causes of hospital admissions, according to a recent study published in the American Journal of Public Health. About one-half of those hospitalized for dehydration died within a year of admission.

A bad case of the flu with fever, diarrhea for any reason, or vomiting can disturb water balance within days or even hours for an older person. Dehydration symptoms include fatigue, headache, dry noses and cracked lips and just general overall feeling lousy.

The older the person, the more quickly they can be dehydrated. One reason is that the elderly become less sensitive to the thirst sensation as they age and they are unaware that they need fluids.

They have less water than a younger person because fat replaces muscle tissue. The percentage of body tissues filled with water declines as the fat percentage goes up. Even physical disability, senility and fear of incontinence can limit water intake to the point where a minor illness can have serious effects.

Drink six to eight cups of liquids daily. It doesn't all have to be plain water but fruit juices, milk, coffee, tea and soft drinks all count towards meeting water needs. Serving water with a meal or having a jug of water within reach of an invalid are good ways to cut down on the need for hospitalization. (MC)

Women's Health And Nutrition
Women's health issues have finally become a potent political concern during the last 4 or 5 years following the 1990 revelation that not enough research was being focused on diseases affecting women. Traditionally, women as research subjects were excluded from health research because the research community assumed that what was true for men was likewise true for women (not true), [e.g. response to dietary changes for lowering cholesterol,] and that monthly hormonal cycles interfere with research designs and make results less reliable (not a valid reason). The Congressional Caucus for Women's Health Issues generated a strong force on Capital Hill, helped push through legislation on women's health, and the Office of Research on Women's Health was created in the National Institutes of Health (NIH). Since then much progress has been made but research into women's health issues has a long way to go.

The major diseases affecting women are heart disease, breast cancer and osteoporosis. All three have nutrition components. While 8 in 10 women reported in a Gallup Survey that they were aware of the relationship between diet and health, one third said they did nothing to lower their chances of developing heart disease, cancer, or osteoporosis. Only a very small percent were concerned about heart disease, yet it is the most common cause of death in women as well as men. Few paid any attention to diet as a form of preventing cancer. Most women believed that there was nothing they could do to lessen osteoporosis and its devastating effects in later years. It's not surprising that in the Survey, weight control was a concern but most women diet for appearance sake rather than the health effects of obesity.

In the fall of 1993, the American Dietetic Association launched a Nutrition and Health Campaign for Women. Four related articles appeared in the September 1993 issue of the Journal of the American Dietetic Association. These articles review what in known about women's nutrition and heart disease, breast cancer, osteoporosis and weight control. In concluding her introduction to the Nutrition & Health Campaign for Women, ADA President Susan Calvert Finn, Ph.D., R.D., concluded with a Ralph Waldo Emerson quote, "What is civilization? I answer, the power of good women." Finn wrote, "For our generation we could paraphrase him: `What is a strong civilization? The power of healthy women.'"

This issue features an article about nutrition and breast cancer. Future issues will highlight other major women's health concerns. (MC)

Diet And Breast Cancer
Breast cancer is the most frequently diagnosed malignancy in women today and its rate is increasing 1% to 2% annually. Breast cancer strikes about 182,000 American women each year and kills 46,000. Two-thirds of these cases are in older women, but it affects younger women (and some 900 men annually) also. One in 8 females born today will develop breast cancer during her lifetime, double the 1940 rate.

Why?

Known risk factors, such as age, early menarche, late age of first pregnancy, late menopause, family history and obesity, account for only 40% to 50% of breast cancer cases; thus the etiology of 50% to 60% of cases is unknown. Diet is suspected particularly dietary fat and perhaps saturated fat. Other nutrients under scrutiny are alcohol and animal protein. Fat is suspect because in animal studies and studies comparing fat consumption in various countries and breast cancer, fat shows up with strong associations. Human studies show conflicting results. In the largest prospective study, the Nurses' Health Study, ongoing investigation of some 80,000 American women has shown no association. Some researchers are currently calling for studies of much lower fat intake of 15% or 20% rather than the present 30% fat recommendations. In a combined analysis of 12 case-control studies, the findings indicated a positive association between breast cancer risk and total, saturated, or monounsaturated fat intake in postmenopausal women; however individual studies show mixed results of weakly positive, weakly negative, or no significant associations. In a new Netherlands study, no significant association was found between total fat intake and breast cancer risk. There was some evidence for a weak positive relationship with saturated fat but not with other types of fat or cholesterol.

Obesity influences breast cancer risk depending upon menopausal status: a negative effect in premenopause (fewer menstrual cycles and less estrogen?) and a promoting effect in postmenopause because fat tissue makes some estrogen. Higher or longer estrogen levels are linked with increased breast cancer incidence. Most authorities discount the possible harmful effects of postmenopausal, low-level estrogen replacement therapy and usually recommend it because of its positive effects in lowering heart disease and osteoporosis.

In a large Canadian study of alcohol and breast cancer, there was no evidence of a positive association in postmenopausal women but there was a trend in premenopausal women. The authors call for more study. In another Canadian study vitamin D deficiency increased breast cancer risk.

Speculation centers on possible protectors as high intakes of soybean products, dietary fiber, fruits and vegetables and some of the antioxidant vitamins, A, C, and E. One of the most promising leads is the protective effect noted for soybean products and phytochemicals. In the Nurses' Health Study, high dietary fiber was not associated with lower rates whereas in a Canadian study, women consuming the most fiber had a 30% risk reduction in breast cancer. Cereal grains and fruits and vegetables appear to be protective.

The final word about diet and breast cancer is yet to be spoken. Some researchers are suggesting that it's the total diet that is important because of interactive factors. Looking at nutrients and dietary components separately may lead to confusion rather than elucidation. The current Women's Health Initiative will look at low-fat, hormone replacement and include more dietary fiber, fruit and vegetables. (MC)
