Handful of nuts 'cuts heart disease and cancer' risk
Conclusions This systematic review finds evidence that nut intake may be linked with reduced risk of cardiovascular disease, cancer and death. The systematic review has several strengths. It identified a large number of studies with a large total sample size. It also included only prospective cohorts assessing nut consumption and then followed up later disease outcomes. It excluded cross sectional studies, which assess diet and disease at the same time, and so can't show the direction of effect. It also excluded cohorts that have retrospectively questioned diet when the person already has the disease, which could be subjec...

New brain diet 'slows mental decline'
ConclusionThis observational study aimed to investigate the relationship between the MIND diet and its protective properties for mental decline in an older population. The study has several strengths, including the large sample size, long observational period of up to nine years, regular annual assessment of cognitive functions, and comprehensive assessment of diet. However, one of the main limitations is that this type of study cannot show cause and effect – it can only show an association between the diet and slower mental decline. There may be other unmeasured factors that account for the results, such as genetics, ...

Half a handful of nuts a day 'reduces early death risk'
Conclusion This Dutch cohort of middle-aged to elderly adults generally found people were less likely to die in the following 10 years if they ate a small number of nuts a day compared with none. The study has strengths in its large sample size and that cause of death was followed up for the full cohort using valid medical codes. However, there are various points to bear in mind before we jump to the conclusion that nuts are the magic ingredient that will slash our risk of death. No clear trends It is difficult to draw any clear interpretations about how nut consumption may be associated with risk of death overall or fr...

Brits eating too much salt, sugar and fat
“Too much sugar, salt and fat: healthy eating still eluding many Britons,” The Guardian reports, while the Daily Mail rather bizarrely warns of a “fruit juice timebomb”. Both papers are covering a major survey that looked at the nation’s eating habits over recent years.The survey found that, overall, adults and children are eating too much saturated fat, added sugar and salt. We are also not getting the recommended levels of fruit, vegetables, oily fish and fibre that our bodies need. Who produced the survey?Public Health England, an agency of the Department of Health, has released data from the National Diet an...

Saturated fat link with heart disease questioned
This article is one doctor's opinion based on his own knowledge, research and experience. However, it is fair to say there is an ongoing debate about how far cholesterol is a risk factor for heart disease, especially in people who are otherwise healthy. There is also a similar debate about the use of statins in people who have no evidence of cardiovascular disease. This is alongside ongoing research into the components of LDL and the different types of lipoproteins known to increase risk the most. None of this relevant new evidence is covered by the news reporting.   What should you eat? There is no need to change curren...

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...
