Simple and cost-effective emails of four every morning helped Canadians increase calcium intake to 200 milligrams per day improved the health of the participants say researchers of University Of British Columbia (UBC).
Mary Jung, an assistant professor of health and exercise sciences at UBC's Okanagan campus, recently completed a nationwide study with more than 730 Canadians who were not meeting Canada's recommended dietary intake for calcium.
‘Your daily dose of calcium can create a positive attitude, healthy behavior, along with improved bone health.’
AdvertisementParticipants received an email--with evidence-based daily tips and strategies on how to increase calcium intake--four days in a row.
Jung, a Michael Smith Foundation for Health Research Scholar Professor, wanted to determine if targeted messaging--making particular outcomes relevant to the population of interest--could be a feasible public health strategy for improving calcium intake.
"Just four targeted messages made a remarkable difference in the consumption of calcium-rich foods," says Jung.
Calcium-rich foods apart from dairy products are green leafy vegetables (kale and broccoli), almonds and canned fish (with bones).
Jung also quoted that, "The majority of our participants increased their calcium intake by one serving of dairy a day--pretty good results."
Rather than tailoring messages to each individual, which can be costly and intrusive, the messages in this study highlighted outcomes Jung had found relevant to her targeted audience.
Specifically, she used evidence-based information including the suggestion of being a positive role model for one's children, understanding the health benefits of consuming enough calcium as we age, and strategies to keep up the required daily consumption.
Despite the known health benefits of getting enough calcium, such as bone health, less than 40 percent of Canadians between the ages of 30 and 50 consume the right amount. Jung notes that this age group tend to encourage their children to drink milk, but forget the importance of ensuring they get enough calcium.
"This study demonstrates that providing salient information, along with relevant how-to strategies, is an effective way to promote calcium intake in Canadian adults," says Jung.
"These findings hold promise for future public health campaigns on a shoestring budget. By making messages meaningful to the targeted audience, cost-efficient messages can change health behaviors."
Jung's research was recently published in the Journal Annals of Behavioral Medicine.
