Western Diet lowers odds of "ideal aging"

Western Diet lowers odds of "ideal aging" | Expertpatient | Scoop.it

Background

The impact of diet on specific age-related diseases has been studied extensively, but few investigations have adopted a more holistic approach to determine the association of diet with overall health at older ages. We examined whether diet, assessed in midlife, using dietary patterns and adherence to the Alternative Healthy Eating Index (AHEI), is associated with aging phenotypes, identified after a mean 16-year follow-up.

Methods

Data were drawn from the Whitehall II cohort study of 5350 adults (age 51.3±5.3 years, 29.4% women). Diet was assessed at baseline (1991-1993). Mortality, chronic diseases, and functioning were ascertained from hospital data, register linkage, and screenings every 5 years and were used to create 5 outcomes at follow-up: ideal aging (free of chronic conditions and high performance in physical, mental, and cognitive functioning tests; 4%), nonfatal cardiovascular event (7.3%), cardiovascular death (2.8%), noncardiovascular death (12.7%), and normal aging (73.2%).

Results

Low adherence to the AHEI was associated with an increased risk of cardiovascular and noncardiovascular death. In addition, participants with a “Western-type” diet (characterized by high intakes of fried and sweet food, processed food and red meat, refined grains, and high-fat dairy products) had lower odds of ideal aging (odds ratio for top vs bottom tertile: 0.58; 95% confidence interval, 0.36-0.94; P=.02), independently of other health behaviors.

Conclusions

By considering healthy aging as a composite of cardiovascular, metabolic, musculoskeletal, respiratory, mental, and cognitive function, the present study offers a new perspective on the impact of diet on aging phenotypes.

"Western-type” diet (characterized by high intakes of fried and sweet food, processed food and red meat, refined grains, and high-fat dairy products) has been attributed to many disease of older age. This study characterizes ideal aging as avoidance of these disease. The additional life style strategies of exercise and smoking are strongly associated with favorable aging but diet is an independent predictor.  It makes common sense that the cumulative effect of daily diet over the middle third of life will have an impact on outcomes in the last third of life.

hmmm - this sounds all to plausible - not sure I am going to share this with my parents - as this will mean they have been on the right path all their lives - searching and reading and modifying their diets to suit the long lives they wish to live. Go Mum and Dad. <yeah, I still didn't share it with them - i can hear the 'i told you so' echoes through from the future> :)

Standard American Diet = SAD diet.  Ancestoral health diets seek historic dietary principles with the goal of restoring/optimizing health and reducing diseases of affluence (diabesity, CHD, etc)

We Sleep How We Eat

We Sleep How We Eat | Expertpatient | Scoop.it
It's no secret: We are what we eat. And turns out, we might sleep how we eat, too.

Found an association between the number of calories consumed and how long the study participants slept. Those who consumed the most were more likely to be "short" sleepers. Interestingly enough, "normal" sleepers were the next type to consume a lot of calories, followed by "very short" sleepers and then "long" sleepers, researchers found.

The impact of poor sleep on craving for carbohydrate is well known.  This may be why there is a link between sleep apnea and obesity.  Poor sleep increases appetite which increases obesity which may cause upper airway obtruction and more sleep apnea that takes us back to an increase in appetite ( a nevere ending cycle).  Anecdotally most people will admit that being up all night at work, or caring for a child results in an almost insatiable appetite the next day.
