Foreword

Cardiovascular disease, including coronary heart disease, strokes, and diseases of other arteries, is a major cause of early death and disability. For many years, the major markers of disease risk have been well recognised; these include high blood cholesterol levels, high blood pressure, obesity, and smoking. But these markers do not account for all cardiovascular risk. Furthermore, treatments that are highly effective in altering these markers, for instance, the ‘statin’ drugs used to lower cholesterol, do not remove risk entirely; typically they reduce it by 30% or less. These observations have prompted a search for other indicators of risk of cardiovascular disease. A number of such risk markers have emerged. These include subtle alterations of types of fat in the bloodstream, factors associated with inflammation and with clotting, lowered resistance to oxidative stress and impaired functioning of blood vessels. In addition, it has been recognised that experiences throughout the life course, even before birth, may influence later disease risk. We still know little about how many of these so‐called ‘emerging’ or ‘novel’ risk markers may be altered to reduce risk of cardiovascular disease, especially how they may be influenced by diet, although the rapid changes in risk of cardiovascular disease that occurred throughout the twentieth century suggest that features of our lifestyle such as diet may play a fundamental role.

In 2005, the first report of this Task Force was published in an attempt to collate all the evidence relating to these emerging risk factors and the role of nutrition. This report has been popular and has been much cited. Since that time, however, the field has moved on. Some of the risk factors that we then considered ‘emerging’ are now well established. Other areas of interest have been added, in particular, the role of the organisms inhabiting the human gut, the ‘gut microbiota’. The British Nutrition Foundation felt that it would be appropriate to re‐convene the Task Force to look at the field again, updating and adding to our previous report.

Some of the authors of the first edition were not available to work on this second edition. We have therefore brought in new authors, but have been assured consistency by the presence of several of the original authors, as well as senior staff at the British Nutrition Foundation.

Each chapter in this report was written initially by between one to three the members of the Task Force, but then all members commented and may have contributed to each chapter. Some of the topics are similar to those considered in the previous edition, but others have been added. The topic of ‘early origins of adult disease’ has evolved into a consideration of life course events. The theme of homocysteine has widened and now we include a chapter on ‘vitamins’. A previous focus on ‘insulin resistance’ has been replaced by a consideration of the effects of obesity and the concept of the metabolic syndrome. We have entirely new chapters on the role of physical activity and inactivity, and on the gut microbiota. As in the previous edition, we have retained a chapter on ‘factors related to adipose tissue’, which we believe will be an important area in the future. The Report includes, as is standard for British Nutrition Foundation reports, a Question and Answer section and a Public Health chapter, in which we hope everyone will be able to find ‘take‐home messages’ emerging from our work, together with chapters summarising the conclusions and recommendations of the Task Force. In addition, a glossary and key references for each chapter can be found at http://www.wiley.com/go/bnf/cardiovascular_diseases.

I would like to thank all the members of the Task Force who worked hard and willingly on this project, and also others who corresponded with us. I extend special thanks to the British Nutrition Foundation staff who participated, both as authors and by providing administrative support. Sarah Coe has worked particularly hard on this project. Finally, on behalf of all members of the Task Force, I wish to pay tribute to George Miller, a contributor to the first edition, who has sadly died in the intervening period.
