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...

Claims that 'butter is safe' and 'margarine deadly' are simplistic
ConclusionThis careful systematic review and meta-analysis of research into the effects of saturated and trans fat on health found no evidence that eating more saturated fat raises the risk of death from any cause, death from cardiovascular disease, or risk of getting heart disease, stroke, or type 2 diabetes. However, the authors say they can only have "very low" confidence in their findings, because of the methodological limitations of the individual studies that contributed data.The study did find a link between eating more trans fats and death from any cause, from heart disease or risk of getting heart diseas...

Following UK dietary advice may cut heart disease risk
Conclusion This study showed that following dietary recommendations closely for 12 weeks can reduce blood pressure by a significant amount, which is likely to cut the chances of having a heart attack or stroke for an average healthy middle-aged person. The diet also affects cholesterol levels, but the overall effect of this may be modest. The study appears to have been carefully conducted to avoid biasing the results. The researchers gave butter or margarine spread and cooking oil to people in both groups, for example, and asked everyone to fill out food diaries, as well as taking urine samples for nutrient analysis. Thi...

Sugar intake linked to heart disease deaths
Conclusion This study used dietary information from a large group of US adults to show that greater added sugar intake was linked to a higher risk of death from CVD. The study has many strengths including recruiting a large number of people and obtaining information spanning a relatively long time – average 15 years. The cohort in question was representative of US adults. Despite some ethnicity differences between the US and UK population that may influence the results, the main link between sugar and CVD death is likely to apply to UK adults. It wasn’t possible to estimate the absolute risk differences of dying from ...

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...

Mediterranean diet cuts heart and stroke risk
Conclusion The results of this randomised controlled trial appear to confirm previous studies that there are benefits to following a Mediterranean diet. The trial has many strengths, including its large size, long period of follow-up, thorough assessment of medical outcomes (including reviewing medical records and having contact with the family doctor), and careful attempts to assess whether the diets were being followed. As this is a randomised controlled trial, it should also balance out other health and lifestyle differences between the groups that may influence cardiovascular risk. This avoids the limitations of m...
