Nut eaters may have a longer life expectancy
Conclusion This study found that eating nuts is associated with a reduced risk of death from any cause, and that the more frequently nuts were eaten, the lower the risk of death. Eating 28g of nuts seven or more times per week was associated with a 20% reduced risk of death. The researchers say that previous studies found that increased nut intake was associated with a reduced risk of several diseases (including type 2 diabetes mellitus, colon cancer, high blood pressure and diverticulitis), and that nut consumption has been linked to reductions in various risk factors for chronic diseases. Seeing whether nut consumption w...

Women who spend too long sitting may die earlier
Conclusion This cohort study looking at the link between sedentary time in postmenopausal women and their risk of death, benefits from its large sample size of almost 100,000 women, and 12 year follow-up. It finds, as previous research has found, that increased sedentary time is generally associated with increased risk of death. The main risk was for women with the highest sedentary time (greater than 11 hours sitting per day) who were at increased risk of death from any cause and deaths from heart disease or cancer compared with women sitting for less than four hours a day. The links were less clear for women sedentary ...

Lack of vitamin D may 'raise dementia risk'
Conclusion This cohort study of more than 1,650 elderly people has found that over 5.6 years, severe vitamin D deficiency is associated with approximately twice the risk of developing dementia or Alzheimer's disease. It also found moderate deficiency is associated with a 50% increase in risk compared with healthy levels of vitamin D. With this being a cohort study, it was not able to show that low levels of vitamin D caused dementia or Alzheimer's disease – it was simply able to show an association. Other factors that can increase the risk of developing dementia, such as a poor diet, lack of activity and general poor h...

Yoga may help protect against heart disease
ConclusionOverall, this review suggests that yoga may be beneficial in reducing risk factors for cardiovascular disease and metabolic syndrome.While these are encouraging findings, the authors also caution that these are based on trials with some limitations, including: There was a wide variation in the type of yoga practised, the frequency and the length of each session across the studies. This means it is difficult to say what the actual effects of each approach are, as the overall effects are just an average across all of these approaches. Some may have more of an effect and some may have less. The review does not rep...

Inactivity 'twice as deadly' as obesity
Conclusion This study’s strengths included its large size and long follow-up period. Researchers also took into account a large number of factors (called confounders) that might have influenced the risk of death, such as diet, smoking history and alcohol intake, although it is still possible that both measured and unmeasured confounders influenced mortality rates. The study had one important limitation. It only measured people’s BMI (calculated by combining their weight and height) and their physical activity once, at the start of the study. It is quite possible that people’s BMI changed over time, and that this wou...

Sugary drinks linked to increased heart failure risk in men
Conclusion This observational study found an association between the consumption of sweetened drinks and risk of heart failure. The study has some strengths, such as the large population size and long follow-up period. However, it has several limitations, which are acknowledged by the researchers. These include the following: The study included middle-aged and elderly men, so the results cannot be generalised to all age groups and genders. The men were all from Sweden, where there is a different typical diet to that of the UK. Researchers collected data on the daily and weekly intake of sweetened drinks in the pa...

Being happy 'won't help you live longer' survey finds
ConclusionThis large prospective study aimed to assess whether happiness or related measures of wellbeing are associated with risk of death, after allowing for the influence of the poor health and lifestyles of people who are unhappy.The study found poor health was linked with unhappiness in middle-aged women. However, after allowing for this association and adjusting for the influence of other factors that may be associated, such as smoking and poor socioeconomic status, happiness and related measures of wellbeing do not appear to have any direct effect on death. This suggests that, as has sometimes previously been specu...

'Dying of heartache?' Heart problems linked to bereavement
Conclusion The study found that people were more likely to have AF for the first time in the weeks immediately after a bereavement, but that this raised risk does not last. Despite the headlines, this does not mean that anyone who's had a bereavement is at immediate risk of "dying of a broken heart". Atrial fibrillation is treatable and not usually life-threatening. Because this was an observational study, we cannot rule out the possibility that factors such as family history of atrial fibrillation or lifestyle factors could have affected the results, although the researcher's conclusion that this is a small poss...

'Tooth loss link to increased risk of dementia'
Conclusion This study adds to the evidence that good oral health is linked to good overall health, including a reduction in the chances of developing dementia in later life. But the research doesn't prove that regular tooth brushing will prevent dementia. We don't know what causes dementia. From research so far, it looks as if there are a number of interlinked causes. Brain health and ageing are likely to be affected by factors including diet, exercise, smoking, alcohol use, blood pressure and genetics. While living a healthy lifestyle may certainly reduce the chances of dementia, there are no guarantees. This study ha...

Binge drinking could trigger abnormal heart rhythms
Conclusion This cross-sectional study found binge drinking is associated with an increased risk of having an irregular heartbeat. However, the type of irregular heartbeat found was mainly sinus tachycardia, which isn't life threatening but involves the heart beating at an abnormally fast rate of over 100 heartbeats a minute. This research also has some notable limitations: The ECG recordings from the acute alcohol group were taken using a smartphone application operated outside the manufacturer's recommended environment. The lively atmosphere within the beer tent may have caused inaccurate recordings. The population...

Beta-blockers 'useless' for many heart attack patients, study reports
Conclusion This study aimed to see whether beta blockers reduce mortality in people who've had a heart attack but who don't have heart failure or systolic dysfunction. It found no difference between those who were and those who were not given beta-blockers on discharge from hospital. The authors say this adds to the evidence that routine prescription of beta blockers might not be needed for patients without heart failure following a heart attack. Current UK guidelines recommend all people who have had a heart attack take beta blockers for at least one year to reduce risk of recurrent events. Only people with heart failure ...

Being overweight, not just obese, still carries serious health risks
Conclusion This impressively large global study demonstrates that the prevalence of obesity is increasing worldwide among both children and adults. It supports what has long been thought, that increased body mass index (BMI) contributes to a range of illnesses and is ultimately responsible for a large number of deaths, particularly from cardiovascular disease. One potential limitation is the use of self-reported BMI or health outcome data in some of the studies, although the majority used a specific independent measurement so this is unlikely to have biased results too much. It is also always difficult from observational d...

Some types of vegetarian diet can raise heart disease risk
Conclusion This large pooled cohort study seems to demonstrate an association between a healthy plant-based diet and reduced risk of coronary heart disease, and an increased risk of heart disease with an unhealthy plant-based diet. This adds to the evidence base supporting the possible benefits of healthy plant-based diets in protecting against certain illnesses. However there are some limitations to the research: The cohort included only health professionals from the US so might not be representative of wider populations in the UK or elsewhere. The study can't provide information on the benefits or otherwise of this d...

Secondhand smoke linked to dementia
Conclusion Secondhand or passive smoking is known to be detrimental to health and has been associated with increased risk of cardiovascular diseases and cancer. However, it is not yet certain whether it is linked to dementia. Though this large study finds a significant link between secondhand smoke exposure and severe dementia syndromes there are several important limitations to be aware of. Problems with measuring dementia diagnoses The method for diagnosis of dementia used by this study was unusual. Though the researchers assessed each individual using a mental state examination, they went on to diagnose them using a com...

Eating your 5 A DAY 'could make you more optimistic'
Conclusion This is well-conducted research which has used a validated measure to assess the optimism of a sample of middle-aged American citizens and measure their blood antioxidant levels. The researchers found a link between higher carotenoid levels and higher optimism, but as the researchers rightly conclude, their findings do not prove cause and effect and it isn’t possible to say in which direction the relationship is going. It is possible that having higher levels of antioxidants in the body leads to better physical health and this in turn enhances optimism, but then it is equally possible that people who are in be...
