Live Long & Prosper Newsletter #5

This newsletter was compiled from the latest research on health and longevity, by David Donohue, MD, FACP. 

Nutrition
1.   Egg consumption in relation to risk of cardiovascular disease and diabetes: a systematic review and meta-analysis.
   Based on 16 studies, people who eat > 1 egg/day have a 42% greater risk of getting diabetes, relative to those who eat less than 1 egg per week.

2.   Effect of the vegetarian diet on non-communicable diseases.
   The science overall is very favorable for vegetarian vs omnivorous diets. E.g. "RRs for all cancers were 0.82 (0.73-0.93) in pescetarian and 0.88 (0.81-0.96) in vegetarians". However "vegetarian diets may lead to an inadequate intake of several important nutrients, particularly Fe, Zn, vitamin B12 and n-3 PUFA, which are associated with some disadvantages and health risks" So perhaps don't be strict and perhaps take a supplementary multivitamin containing just a little zinc, iron, B12 and omega-3s.

Exercise
1.   A non-exercise testing method for estimating cardiorespiratory fitness: associations with all-cause and cardiovascular mortality in a pooled analysis of eight population-based cohorts.
   Ho hum another big study shows people who are physically fit live longer.

2.   The role of physical activity in cancer prevention, treatment, recovery, and survivorship.
   With all these studies the question is: is this association causal or not? For this review, they found " all-cause mortality in cancer survivors decreases with increasing amounts of exercise". Does the exercise reduce your risk of cancer recurrence? Or are people who are not likely to get cancer recurrence for other reasons, happen to walk more? We don't know but I figure better to put yourself in the lower risk category if you can!

Lifestyle
1.   Multicenter, Randomized Controlled Trial of Yoga for Sleep Quality Among Cancer Survivors.
   Cancer survivors have a high incidence of sleep problems. Yoga helps these problems.

2.   Smoking status, physical health-related quality of life, and mortality in middle-aged and older women.
   Women who smoke have lower quality of life and higher mortality. The more you smoke, the bigger the effect.

Prevention
1.   Mediterranean Diet and Cardiovascular Disease: Historical Perspective and Latest Evidence
   "Contrary to the pharmacological approach of cardiovascular prevention, the adoption of the Mediterranean diet has been associated with a significant reduction in new cancers and overall mortality". If you have high cholesterol, it might be just as important to switch to a Mediterranean-style diet as it is to take medications to lower your cholesterol.

2.   The joint association of physical activity, blood-pressure control, and pharmacologic treatment of hypertension for all-cause mortality risk.
   "Physical activity may be as or even more important than pharmacotherapy for reducing the risk of mortality in adults with hypertension. However, the risk of mortality remained higher for physically active adults with treated and controlled hypertension than did the risk of mortality for physically active normotensive populations. Prevention of hypertension is therefore imperative for reducing the all-cause risk of premature mortality in adults. " We have been telling patients to think of physical activity as the most important medication you can take. Take it every day.

Safety
1.   Light physical activity is a better determinant of lower adiposity during the menopausal transition.
   Starting menopause? Lighter-intensity physical activity was best to prevent fat gain.

2.   Diet and food allergy development during infancy: Birth cohort study findings using prospective food diary data.
   More helpful tools for nagging your daughter-in-law: "An infant diet consisting of high levels of fruits, vegetables, and home-prepared foods is associated with less food allergy by the age of 2 years."

3.   [Cognitive behavioral therapy for chronic insomnia].
   Have insomnia? Consider seeing a therapist. Cognitive Behavioral Therapy improved insomnia in 80% tested.
