DIARY IS GOOD FOR YOUR METABOLIC HEALTH
Dairy is considered
part of a healthy diet and dietary guidelines recommend the daily consumption
of 2-4 portions of milk-based products such as milk, yogurt, cheese, cream and
butter
It's well known that
dairy products contain calcium and minerals good for bones, but new research
has shown that dairy consumption may also have beneficial effects on metabolic
health and can reduce risk of metabolic diseases such as obesity and type 2
diabetes.
Curious about these
impacts, researchers from CHU de Québec Research Center and Laval University
studied the dairy-eating habits of healthy French-Canadians' and monitored how
dairy consumption may have an effect on their overall metabolic health. They
published their findings today in the journalApplied Physiology, Nutrition,
and Metabolism.
The aim of this study
was to determine associations between dairy intake and specific metabolic risk
factors, including anthropometric status, plasma glucose, plasma lipid profile,
inflammatory markers and blood pressure, in a healthy population.
A total of 254
participants from the greater Quebec City metropolitan area were recruited; 233
participants (105 men and 128 women) met all the eligibility criteria for the
study ‒ meaning subjects had
healthy metabolic profiles.
The study showed that
the average individual consumed 2.5 ± 1.4 portions of dairy per day. However,
nearly 45% of the population in this study did not meet Canada's Food Guide
recommendations of at least 2 portions of dairy products a day. These findings
are supported by recent Canadian surveys that highlighted an under consumption
of dairy products by Canadians.
Data suggest that
trans-palmitoleic acid found in plasma may be potentially used as a biomarker
to evaluate dairy consumption. Trans-palmitoleic acid, is naturally present in
milk, cheese, yogurt, butter, and meat fat but cannot be synthetized by the
body. This fatty acid has been recently shown to have health-promoting effects.
In this study, that trans-palmitoleic acid level was related to lower blood pressure
in men and women, and to lower body weight in men.
Dairy intake is
associated with lower blood glucose and blood pressure in the population
studied, though no causal relationships can be made due to the cross-sectional
design. This study adds to a growing body of literature demonstrating a lack of
detrimental health effects with higher dairy intake.
Dr. Iwona Rudkowska, a
research scientist at the Endocrinology and Nephrology Department, at the CHU
de Québec Research Center and assistant professor at Laval University , says
"additional well-designed intervention studies are needed to ascertain the
effects of increased dairy consumption on metabolic health in healthy and in
metabolically deteriorated populations."
