Giving babies healthy foods early may shape childhood tastes | Reuters

Even if you have a lot of other priorities for instance, sports, extracurricular activities, etc., still you need to complete a senior project to graduate successfully

Young toddlers who eat a range of fruits and vegetables may learn to enjoy healthy eating as they grow older, an Australian study suggests.

Researchers found that 14-month-old babies who regularly ate fruits and vegetables were more likely to eat them and less likely to be fussy eaters when they were nearly four years old.

The take-home message for parents is pretty simple: introduce your toddler to a range of healthy foods early . . . this means offering your child a variety of different fruits and vegetables, said lead author Kimberley Mallan, a researcher at the Institute of Health and Biomedical Innovation, Queensland University of Technology in Brisbane.

Children need to learn to like some foods, particularly vegetables, and repeated, neutral exposure is the best approach, she said.

Food preferences are developed as early as the first two years of life, Mallan and colleagues write in Journal of the Academy of Nutrition and Dietetics. But up to a third of children do not eat fruits and vegetables in their first three years and most eat unhealthy snack foods, according to past research.

About a fourth of Australian children and nearly a third of American youth are overweight or obese, the authors note.

The researchers compared the dietary habits of 174 children whose mothers received nutrition counseling to 165 who did not. All were part of a larger Australian study of mothers and children from Brisbane and Adelaide, starting in 2008 and 2009.

Dietitians and psychologists counseled the mothers in six 1.5- to 2-hour interactive group sessions every two weeks. Data on babies were collected at birth, age four months and age 14 months, with follow-up at two years and 3.7 years.

Researchers used various scales and questionnaires to measure the number of fruits and vegetables and noncore foods the children tried weekly at each age. Noncore foods are not in the core food groups like milk, which babies and young kids should consume every day, according to nutrition guidelines. They include cookies, candy, salty snacks and other less-healthy foods.

Both groups of mothers had about the same number of fussy kids at age 14 months.

The babies who tried a greater number of fruits and vegetables liked these foods more at 3.7 years than those who did not eat the items when they were younger. Eating a greater number of noncore foods as an infant was also associated with liking those snacks more as a 3.7-year-old.

Parents are not depriving their child by not offering these foods, rather they are investing in their childs long-term health . . . , Mallan said by email to Reuters Health.

The associations were still strong after accounting for maternal age at delivery, education and BMI, the childs sex, breastfeeding duration, age when solid foods were introduced and infant fussiness.

Trying fewer vegetables (though not fruits and non-core items, which tend to be sweeter) as infants was also tied to more fussiness as children.

Lara Field, a registered dietitian with a nutrition counseling practice in Chicago, said the results might not correlate to the U.S. because of different obesity rates, cultural factors, accessibility to fresh food or popularity of fast food. But the study reinforces the importance of introducing healthy foods early and encouraging children to eat fruits and vegetables, rather than filling up on unhealthy snacks, she said.

When children reject a food, is it because they dont like it, or is it because they have been fed too many snacks throughout the day, and are simply too full to be interested in food? When approached with a plate of broccoli, they may reject it, but if they were hungry, perhaps they would have been more willing to eat it, Field said in an email.

Parents also need to adopt the same healthy eating they expect of their kids and find ways to make meals enjoyable, said Field, who was not involved in the study.

Bottom line, kids mimic what they see at home, said Field. If you want your kids to eat veggies, you need to also.

Foods every breast cancer survivor should know about



Even if you have a lot of other priorities for instance, sports, extracurricular activities, etc., still you need to complete a senior project to graduate successfully

Story highlightsStudies have showed that eating certain foods may lower a survivor's risk of recurrenceConsumption of isoflavones, commonly found in soybeans, are linked to reduced riskStudy: Carotenoids associated with "greater likelihood of breast cancer-free survival"Eating fish high in omega-3 fatty acids linked to an improved breast cancer prognosisWomen checking in for appointments at the Comprehensive Breast Center at St. Luke's-Roosevelt Hospital Center in New York this month are being offered more than a pre-op or post-op surgical visit.

On the reception desk, inside a large plastic frame, is a colorful flyer decorated with pictures of luscious-looking fruits and vegetables. It's an invitation to attend "Superfoods and Super Habits for Super Health," a seminar that promises to teach patients the foods they should eat to boost their immunity and -- not in so many words -- reduce their chances of dying of breast cancer.

"We have to take a global look at survivorship," said Dr. Alison Estabrook, chief of breast surgery at St. Luke's-Roosevelt and director of the Breast Center. "It's clear better eating habits increase the possibility that a woman won't get breast cancer or have a recurrence."

The good news is that after two decades of breast cancer being on the rise, numbers have been declining in recent years. Still women in the United States have a one in eight chance of developing breast cancer in their lifetime, according to the ACS, so it's not surprising experts are searching for more ways to keep them alive.

Not all oncologists embrace the link between nutrition and longevity, citing insufficient evidence. But doctors who specialize in nutrition say there are certain foods women can include in an overall healthy diet to increase their chance of survival.

Soy

Dr. Barry Boyd, creator of the integrative medicine program at Greenwich Hospital-Yale Health Systems and director of nutritional oncology, says women should no longer be afraid to consume soy.

"It was feared that components of soy had estrogen-like properties that influenced the growth of breast cancer cells," Boyd said. "Science has not only proved an absence of risk, there's also a possible benefit."

Boyd points to a study in the American Journal of Clinical Nutrition that explored soy intake in the United States and China among 9,500 women after breast cancer diagnosis. The consumption of isoflavones, commonly found in soybeans, produced a "statistically significant reduced risk of recurrence" among breast cancer survivors diagnosed with invasive breast cancer, according to researchers.

A study released this year by the Asian Pacific Journal of Cancer Prevention produced similar results. In this analysis, more than 11,000 breast cancer patients were studied. Researchers concluded that eating soy after diagnosis was associated with a reduced mortality risk and fewer recurrences of the disease.

The American Cancer Society is more cautious in its recommendations, noting that while soy is good source of alternative protein, "women with breast cancer should take in only moderate amounts" and not ingest soy-containing pills, powders or supplements containing high amounts of isoflavones.

Kale, sweet potatoes and squash

Eating foods rich in carotenoids has been linked to a reduced risk of breast cancer recurrence. Carotenoids are the natural pigments found in yellow and orange foods (such as carrots, sweet potatoes and squash) and dark leafy greens such as kale, spinach and Swiss chard.

In a 2009 study published in the journal Cancer Epidemiology, Biomarkers & Prevention, increased consumption of carotenoids was associated with "greater likelihood of breast cancer-free survival." The report based its findings in part on the Women's Healthy Eating and Living Study, a National Institutes of Health-funded investigation.

To increase the consumption of carotenoids, Dr. Mitchell Gaynor advises his breast cancer patients to eat more cruciferous vegetables. Gaynor, founder of Gaynor Integrative Oncology, says his reasoning is simple: "We understand cancer quite differently today than we did when President Nixon declared a war on cancer in the 1970s. We know now that certain foods make your body inhospitable for cancer cells to thrive. The goal is to keep cancer cells dormant, and what you eat makes a difference."

Examples of cruciferous vegetables include broccoli, kale, cabbage and cauliflower.

Salmon, haddock and cod

Eating fish high in omega-3 fatty acids has also been linked to an improved breast cancer prognosis. Fish in this category include salmon, haddock, cod, halibut and sardines.

A 2011 study in the Journal of Nutrition showed that the consumption of EPA and DHA fatty acids from fish "inhibit the proliferation of breast cancer cells" and reduces "the progression of breast tumors." Women who were diagnosed and treated for early stage breast cancer -- and given higher levels of EPA and DHA -- had an approximate 25% reduced risk of recurrence.

It's important to note that the benefit corresponded only to the consumption of fish, not fish oil supplements.

Gaynor says that eating fish rich in omega-3 fatty acids is also healthful because it supports proper immune function and lowers a woman's risk of heart disease and diabetes.

The American Cancer Society warns against eating too many of these fatty foods: "Diets high in fat tend to be high in calories and may contribute to obesity, which in turn is linked with an increased risk of several types of cancer."

Beans and whole grains

Women who consume a high-fiber diet probably boost their life expectancy.

"A high-fiber diet is associated with lower overall mortality in breast cancer patients," said Dr. Keith Block, medical-scientific director at the Block Center for Integrative Cancer Treatment in Skokie, Illinois.

Block says fiber is beneficial because it can help women control their appetite and may decrease the number of calories they consume. Achieving and maintaining a healthy weight, particularly after menopause, is widely viewed as one factor that influences survival.

Which is why Estabrook at the Comprehensive Breast Center is offering that nutrition class in the first place.

"When you look at cancers, most are caused by weight gain," she said. "The fatter you are, the more estrogen circulates in your body, and when there's more estrogen, the risk of breast disease increases.

"But cancer survival is not just about eating one kind of fruit or vegetable. It's about making the right lifestyle choices, including exercise. Diet is one part of a larger picture."
