‘Weekend warriors’ get same cardiovascular benefit as regular exercisers
Engagement in moderate to vigorous physical activity (MVPA), with most activity concentrated within one to two days of the week (i.e, a “weekend...
Whole-fat dairy included in healthy low mortality risk diet
A call for a re-evaluation of “unrelenting guidelines” to avoid whole-fat dairy products has been made by the authors of a study who have found that a healthy diet, including whole-fat dairy, is associated with lower risk of mortality and cardiovascular disease (CVD).

In their study published online in the European Heart Journal, Andrew Mente, Ph.D., from Hamilton Health Sciences and McMaster University in Canada, and colleagues developed a healthy diet score in 147,642 people from the general population from 21 countries (the PURE study) and examined the consistency of the association in five independent studies from 70 countries.
The healthy diet score was developed based on six foods that have all been associated with significantly lower mortality risk (fruit, vegetables, nuts, legumes, fish, and dairy [mainly whole-fat]).
All-cause mortality and major cardiovascular events were the main outcome measures.
The researchers found that in PURE, a diet score of ≥5 points was associated with a lower risk of mortality, CVD, myocardial infarction, and stroke compared with a diet score of ≤1 during a median follow-up of 9.3 years (hazard ratios, 0.70, 0.82, 0.86, and 0.81, respectively).

Similar results were found in three independent studies in vascular patients, with a higher diet score linked to significantly lower mortality, CVD, and myocardial infarction (hazard ratios, 0.73, 0.79, and 0.87, respectively), while the risk for stroke was non-significantly lower.
A higher diet score was associated with lower first myocardial infarction and stroke in two case-control studies (odds ratios, 0.72 and 0.57, respectively).
“The new results in PURE, in combination with prior reports, call for a re-evaluation of unrelenting guidelines to avoid whole-fat dairy products,” the author of an accompanying editorial wrote.
