Review finds no link between dairy and heart attack or stroke risk
Conclusion This large meta-analysis of cohort studies demonstrated no increased risk to cardiovascular disease, coronary heart disease or all-cause death from eating dairy products. The review has strengths in its large size and the fact it was able to analyse different types of dairy product, such as high and low-fat and everyday products such as cheese and yoghurt. However, there are a number of factors to consider: The results of a systematic review are only as good as the quality of the underlying studies. These are all observational studies and it's possible that unadjusted health and lifestyle factors are having an...

'Stop demonising butter,' say researchers
Conclusion This systematic review and meta-analysis assessed the long-term association between butter consumption and major health conditions, such as cardiovascular disease, diabetes and death. The nine identified studies found little to no evidence that butter consumption increased the risk of death, cardiovascular disease, heart disease or stroke. Perhaps surprisingly, though, there did seem to be a protective effect against the risk of type 2 diabetes. This review has both strengths and limitations that may affect the reliability of the findings. The researchers used careful search methods that aimed to identify onl...

'Chocolate good for the heart' claims sadly too good to be true
Conclusion Health stories that suggest eating or drinking something we like, whether it's chocolate or wine, are always popular. But they don't really tell us anything we don't know already. Certain foods may have a small impact on certain types of diseases, but it's the overall diet that counts. Previous studies have already suggested that the antioxidant properties of cocoa could reduce the risk of cardiovascular disease, so it's surprising that this study focused on one particular cardiovascular disease, atrial fibrillation. AF is a common condition that affects heart rate, often causing a faster than normal, irregular ...

Does coffee make you live longer?
Conclusion This study, conducted on a large number of people across Europe, was backed up by similar findings in the US. It appears to show some association between people who drink higher amounts of coffee and a reduced risk of death. But the "potentially beneficial clinical implications" need to be considered carefully for a number of reasons: Although the analyses were adjusted for some confounding variables, there may be a number of other factors that differ between the groups that account for the differences in death, such as socioeconomic status, family history, other medical conditions, and use of medic...

Healthy diet could cut risk of Alzheimer's disease
ConclusionThe study found people who ate a healthy diet – with plenty of green vegetables, wholegrains, legumes and less red meat – may be less likely to get Alzheimer's disease. However, we should be wary of saying that their diet actually protected them from Alzheimer's, as it is a complex disease with many potential causes.The main limitation is that observational studies cannot prove causation, even when researchers take care, as they did here, to include factors that we know affect disease risk. It's also notable that the researchers excluded dementia, other than Alzheimer's disease, from their calculations. It wo...

Obesity 'now a leading cause of death; especially in men'
Conclusion The effect of being overweight or obese on length of life has been discussed a lot in recent years, mainly because of studies which seemed to show people might live longer if they have a BMI in the overweight range, and that even moderate obesity did not raise the risk of death. However, this study suggests the previous findings were due to confounding factors – such as smoking and pre-existing diseases – which masked the link between BMI and length of life. The overall conclusion is that weight does matter, especially for men and younger people, who seem most affected by the link between BMI and early deat...
