Total and Full-Fat, but Not Low-Fat, Dairy Product Intakes are Inversely Associated with Metabolic Syndrome in Adults


Background: Growing evidence suggests that dairy products may have beneficial cardiometabolic effects. The current guidelines, however, limit the intake of full-fat dairy products.
Objective: We investigated the association of dairy consumption, types of dairy products, and dairy fat content with metabolic syndrome (MetSyn).
Methods: We analyzed baseline data of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a multicenter cohort study of 15,105 adults aged 35–74 y. We excluded participants with known diabetes, cardiovascular diseases, or other chronic diseases, and those who had extreme values of energy intake, leaving 9835 for analysis. Dairy consumption was assessed by a food-frequency questionnaire. We computed servings per day for total and subgroups of dairy intake. We computed a metabolic risk score (MetScore) as the mean z score of waist circumference, systolic blood pressure, HDL cholesterol (negative z score), fasting triglycerides, and fasting glucose. We performed multivariable linear regression to test the association of servings per day of dairy products with MetScore.
Results: In analyses that adjusted for demographics, menopausal status, family history of diabetes, dietary intake, nondietary lifestyle factors, and body mass index, we observed a graded inverse association for MetScore with total dairy (−0.044 ± 0.01, P = 0.009 for each additional dairy servings per day) and full-fat dairy (−0.126 ± 0.03, P < 0.001) but not with low-fat dairy intake. Associations were no longer present after additional adjustments for dairy-derived saturated fatty acids.
Conclusions: Total and especially full-fat dairy food intakes are inversely and independently associated with metabolic syndrome in middle-aged and older adults, associations that seem to be mediated by dairy saturated fatty acids. Dietary recommendations to avoid full-fat dairy intake are not supported by our findings.

That is good to know. I dream of real milk. The taste is so unbelievably good.

Jan, thank you. I was surprised when Sherry contacted me. I considered it a great honor.

I am sick so seldom I don't think it's safe for me to post...the wicked witch rears her ugly head. My Halloween was uneventful. I have one wish stop coughing.

Have a blessed week.

Many thanks for taking time to comment Gail, especially when you are feeling under the weather. If other readers want to know why Sherry contacted you they can hop over and have a look here

Hope that cough soon goes ...

I for one enjoy some full fat milk in my cup of tea, I also enjoy full fat cheese and not the types that are 33% (or similar) low fat!!!

All the best Jan

I don't tolerate cow dairy but I can drink goat milk. I've read that full fat dairy is helpful in preventing cancer too. I wonder how long it will take for nutritionists to admit that they were wrong about milk fat!

I tend to avoid dairy, I eat soya yoghurts, and have low fat milk in my tea.
In saying that I do have a passion for goats cheese and mozzarella, which I have occasionally. This post has now got me thinking ..............

Thanks for your comment Linda.
Yes, not everyone tolerates cow dairy and there are alternatives available. Food sensitivities and allergies must always be taken into account.
It is also important for young children to drink full fat milk for the dietary requirements they need, and guidance is usually given on this from their health care team.
There are many excellent studies/reports available online for us to read in order that we can all make informed choices to suit our needs and lifestyle.

All the best Jan

Many thanks for your comments Cheryl ... like you I love goats cheese and mozzarella, but have always preferred full fat milk with my tea ... and cream with my coffee!
We always try to provide a wide depth of reports, information ... food for thought!

All the best Jan

Call me perverse but I still prefer low fat milk in my coffee. However I make up for it with butter, cheese and cream.

Thabks for reminding me about goat cheese, I used to make mini-cheesecakes with an oatcake spread with a thick layer of goat's cheese and studded with blueberries.

If you like low fat milk in your coffee ... so be it. We all have to enjoy our coffee and tea how we like it, and many drink coffee black!
I also enjoy butter, cheese and cream ... and yes goats cheese is something we have, but there are so many great cheese available. I do like the sound of your mini-cheesecakes, will you be making them again soon?

All the best Jan
