Key takeaways:

  • A weekly consumption of 14 or extra potatoes was tied to a decrease threat for loss of life vs. an consumption of six or fewer potatoes.
  • Every 100 g per day increment of potatoes was related to a 4% decrease threat for loss of life.

A better weekly consumption of potatoes decreased the danger for all-cause mortality in addition to mortality from CVD, ischemic coronary heart illness and acute myocardial infarction, a Norwegian-based cohort research confirmed.

Potatoes have beforehand been tied to decrease mortality in individuals with diabetes, significantly when consumed within the morning.

Nevertheless, most knowledge on potatoes and mortality are restricted, in response to Erik Kristoffer Arnesen, a PhD scholar on the College of Oslo in Norway, and colleagues.

“Furthermore, the particular strategies of preparation are sometimes not detailed, but they will considerably affect the dietary profile of potatoes, as an illustration by way of added fat and sodium,” they wrote within the Journal of Vitamin.

The researchers assessed the impact of principally boiled potatoes on loss of life from all-causes, CVD, ischemic coronary heart illness (IHD) and acute myocardial infarction (AMI) amongst 77,297 adults (50.5% males) who had attended three well being screenings between 1974 to 1988. The contributors’ imply age at baseline was 41 years. At every screening, they reported info on dietary consumption by way of meals frequency questionnaires.

On common, Arnesen and colleagues discovered that males consumed extra potatoes than ladies, and the prevalence of diabetes was highest in these with low potato consumption.

Throughout a median follow-up of 33.5 years, there have been 27,848 whole deaths, together with 9,072 deaths from CVD, 4,620 deaths from IHD and three,207 deaths from AMI.

The researchers reported that contributors who consumed 14 or extra potatoes per week had a decrease threat for all-cause mortality vs. those that consumed six or fewer potatoes (HR= 0.88; 95% CI, 0.84-0.93).

As well as, those that consumed 14 or extra potatoes per week additionally had a touch decrease threat for loss of life from CVD (HR = 0.96; 95% CI, 0.88-1.04), IHD (HR = 0.97; 95% CI, 0.85-1.1) and AMI (HR = 0.99; 95% CI, 0.85-1.15) in contrast with those that consumed six potatoes or fewer.

In analyses of cumulative intakes, every 100 g per day increment of potatoes was related to a 4% decrease threat for loss of life from:

  • all-causes (HR = 0.96; 95% CI, 0.94-0.98);
  • CVD (HR = 0.96; 95% CI, 0.93-0.99);
  • IHD (HR = 0.96; 95% CI, 0.91-1); and
  • AMI (HR = 0.96; 95% CI, 0.91-1.01).

The findings remained related after the researchers adjusted for BMI, smoking standing and bodily exercise, though the associations between potato consumption and mortality from CVD, AMI and IHD have been solely vital in males, Arnesen and colleagues reported.

Concerning potential mechanisms behind the outcomes, the researchers famous that potatoes accounted for 20% and 26% of dietary fiber and vitamin C consumption in males, respectively, which have been related to decrease all-cause and CVD mortality.

The researchers identified that as a result of the cohort was made up of a Norwegian inhabitants and primarily based on diets from the Nineteen Seventies and Eighties, the research’s generalizability to different populations with completely different dietary patterns could also be restricted.

Nonetheless, the findings add to literature that potato consumption “doesn’t adversely have an effect on well being outcomes and could also be a big half of a nutritious diet,” they concluded.
