High-fat dairy products linked to
reduced type 2 diabetes risk
A new study indicates that high-fat dairy products specifically that are associated with reduced risk. The findings, which have been published in the American Journal of Clinical Nutrition, are in line with previous studies of eating habits that indicated a link between high consumption of dairy products and a reduced risk of type 2 diabetes, But focuses on the fat content, which previous studies did not.
"Those who ate the most high-fat dairy products had a 23 per cent lower risk of developing type 2 diabetes than those who ate the least. High meat consumption was linked to an increased risk of type 2 diabetes regardless of the fat content of the meat", said Ulrika Ericson, who conducted the study.
The researchers studied the eating habits of 27 000 individuals aged 45 to 74. The participants took part in the Malmö Diet and Cancer study in the early 1990s, in which they provided details of their eating habits. Twenty years on, over ten per cent - 2 860 people - had developed type 2 diabetes.
The aim of the study has been to clarify the significance of fat in food for the risk of developing type 2 diabetes. Instead of focusing on the total intake of saturated fat, the researchers looked at different sources of saturated fat.
Both meat and dairy products contain saturated fat, but certain saturated fatty acids are particularly common in dairy products. This difference could be one of the reasons why most studies show that those who eat meat are at higher risk of type 2 diabetes, whereas those who eat a lot of dairy products appear to have a lower risk.
"When we investigated the consumption of saturated fatty acids that are slightly more common in dairy products than in meat, we observed a link with a reduced risk of type 2 diabetes. However, we have not ruled out the possibility that other components of dairy products such as yoghurt and cheese may have contributed to our results. We have taken into account many dietary and lifestyle factors in our analysis, such as fermentation, calcium, vitamin D and physical activity. However, there may be other factors that we have not been able to measure that are shared by those who eat large quantities of high-fat dairy products. Moreover, different food components can interact with each other. For example, in one study, saturated fat in cheese appeared to have less of a cholesterol-raising effect than saturated fat in butter.
"Our results suggest that we should not focus solely on fat, but rather consider what foods we eat. Many foodstuffs contain different components that are harmful or beneficial to health, and it is the overall balance that is important."
Dairy is good for 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 journal Applied 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.”
