These products will reduce the risk of premature death and heart disease

Compared to the no intake group, the high intake group, who had a mean intake of 3.2 servings of dairy per day, had lower rates of total mortality (3.4 per cent compared with 5.6 per cent), non-cardiovascular mortality (2.5 per cent vs 4 per cent), cardiovascular mortality (0.9 per cent vs 1.6 per cent), major cardiovascular disease (3.5 per cent vs 4.9 per cent), and stroke (1.2 per cent vs 2.9 per cent).

The observational see became as soon as in accordance to files from about 136,000 adults who took share within the Prospective Urban Rural Epidemiology (PURE) see, which unruffled weight loss program and successfully being files from folks in 21 worldwide locations on 5 continents.

Now, a new study published in the Lancet says three servings of dairy a day is linked to lower rates of cardiovascular disease and death.

Associate Professor Anna Rangan, of Sydney University in Australia, said of the findings: "The results from the PURE study seem to suggest that dairy intake, especially whole-fat dairy, might be beneficial for preventing deaths and major cardiovascular diseases".

They say that the findings are not "the ultimate seal of approval for recommending whole-fat dairy over its low-fat or skimmed counterparts". The researchers are now performing another analysis of the data, one looking at the association between dairy and cardiometabolic risk factors, and they have observed significantly lower blood pressure among those who consumed more dairy, she said. Although the consumption of dairy was not associated with a reduction in MI, the risk of stroke was 34% lower among those had at least three daily servings compared with those who ate no dairy at all.

To TCTMD, Dehghan stressed that PURE is the first multinational study that includes low- and middle-income countries looking at the association between dairy consumption and clinical outcomes.

But researchers said they found those who consumed three servings of milk, cheese, butter or cream per day were nearly two times less likely to suffer from heart disease and strokes, compared to having fewer servings, the Daily Mail reports.

The Centers for Disease Control and Prevention's dietary guidelines for 2015 to 2020, for instance, suggests eating fat-free or low-fat dairy in its key recommendations.

Furthermore, one or more serves of milk and yoghurt - but not butter and cheese - were linked to lower rates of total mortality and cardiovascular disease, compared to those who ate none.

"It's time Public Health England and the British Heart Foundation change their guidance immediately and issue a full public apology that for decades they got it wrong because the science linking saturated fat and heart disease was fatally flawed".

"We are suggesting that dairy consumption should not be discouraged", lead investigator Mahshid Dehghan, PhD (McMaster University, Hamilton, Canada), told TCTMD. These guidelines are based on evidence that consuming too much saturated fat is known to increase cholesterol levels, which is a known risk factor for heart and circulatory diseases. But dairy contains many other components which may be healthy, such as amino acids, vitamin K, calcium, and magnesium.

There were no noteworthy connections between myocardial infarction and dairy intake (HR 0.89, 95% CI 0.71-1.11; P=0.163). "Three servings is moderate consumption, and moderate consumption is beneficial".

That said, people should stick to low-fat dairy, she advised. While multiple weighted food records may be more accurate, they require extensive training, motivation, awareness and literacy which limits the practicality for such a large long-term study.

What's especially interesting is that the paper adds to increasing evidence that full-fat dairy in particular need not be feared. "However, ideally our findings require confirmation in randomized trials evaluating the effects of increasing dairy consumption on BP, glucose, and clinical outcomes", Dehghan added.
