Zo jong mogelijk water bij de maaltijd*
Uit een paar kleine studies van twee Amerikaanse universiteiten blijkt als conclusie dat het drinken van water bij de maaltijd de manier van eten kan veranderen en dat dit het beste op zo jong mogelijke leeftijd kan beginnen. De smaak wordt nl. duidelijk beïnvloedt door herhaaldelijk eten en drinken van bepaalde voeding. Zo zijn zij die altijd frisdranken drinken bij de maaltijd geneigd om meer zoute, vette en calorierijke voeding te nemen en duidelijk minder groenten. Dit is voeding die op termijn leidt tot overgewicht en andere ziektes. Het drinken van water zorgt verder dat men niet teveel eet en er minder kans is op dehydratie. Volgens verschillende onderzoek lijkt het dat wel 75% van de Amerikanen een chronische dehydratatie heeft.
Begin Early: Water With Meals May Encourage Wiser Choices
Water could change the way we eat. That's the conclusion of new research by T. Bettina Cornwell of the University of Oregon and Anna R. McAlister of Michigan State University. Their findings appear online this week ahead of regular publication by the journal Appetite.
The paper featured separate studies. One involved a survey of 60 young U.S. adults (ages 19-23) about the role of food-and-drink pairings. The second involved experiments with 75 U.S. children (ages 3-5) to determine the role of drinks and vegetable consumption. The same preschoolers were tested on different days under differing scenarios involving drinks served with vegetables.
Older participants favored the combination of soda served with salty, calorie-dense foods rather than soda and vegetables. Preschoolers ate more raw vegetables, either carrots or red peppers, when accompanied with water rather than when accompanied by a sweetened beverage.
"Our taste preferences are heavily influenced by repeated exposure to particular foods and drinks," said Cornwell, the Edwin E. & June Woldt Cone Professor of Marketing in the Lundquist College of Business at the UO. "This begins early through exposure to meals served at home and by meal combinations offered by many restaurants. Our simple recommendation is to serve water with all meals. Restaurants easily could use water as their default drink in kids' meal combos and charge extra for other drink alternatives."
Serving water, McAlister said, could be a simple and effective dietary change to help address the nation's growing obesity problem, which has seen increasing number of diabetes cases in young adults and a rise in health-care costs in general. Drinking water with meals, Cornwell said, also would reduce dehydration. While estimates of dehydration vary by sources, many estimates suggest that 75 percent of adult Americans are chronically dehydrated.
From an early age, Cornwell said, children learn to associate sweet, high-calorie drinks such as colas with salty and fatty high-calorie-containing foods like French fries.
"While this combining seems as normal as rainfall in Northwest winters, when we look cross-culturally we can see that food-and-drink combinations are developed preferences," she said. "If the drink on the table sets the odds against both adults and children eating their vegetables, then perhaps it is time to change that drink, and replace it with water."
In January 2011, Cornwell and McAlister reported in the same journal that a child's taste preferences for salt, sugar and fat are related to their knowledge of fast food and soda brands.
These studies suggest that early palate development may influence choices later in life, McAlister said. "From a policy perspective, this means that we need focus on early preference formation."
"This important research has broad ramifications for how foods are marketed and served," said Kimberly Andrews Espy, vice president for research and innovation at the UO. "Addressing the early contributors of unhealthy eating that contribute to obesity is important for our general well-being as a nation and, especially, for improving the nutritional choices our children will make over their
lifetimes." (Augustus 2012)
