2OverviewDoes a Mediterranean diet reduce risk of heart disease and diabetes?What is the Mediterranean diet?TEAM-MED research study
3Heart diseaseIn NI, over 75,000 people with heart disease and 1 in 4 people die each year due to heart diseaseDiabetes is a major risk factor for heart diseaseMost deaths could be prevented by making lifestyle changes such as eating a healthy diet…BHF, 2013 & NHS, 2012
4Mediterranean Diet and Heart Disease Seven Countries Study (1968)Disease rates and dietary patterns differed across countriesMediterranean diet responsible?RESEARCHKeys et al., 1986
5Does a Mediterranean diet reduce risk of heart disease and diabetes?
6Predimed Study People: 7447 adults at risk of heart disease Groups: Med diet and olive oilMed diet and nutsLow fat dietOutcome: Heart related death, heart attack, stroke or diabetesDuration: 5 years
7PREDIMED Study Year Heart events over 5 years Low fat diet 60Med diet + nuts50% people had heart event4030Med diet + olive oil2010YearEstruch et al., 2013
8Survival without diabetes over 5 years (non-diabetic individuals) PREDIMED StudySurvival without diabetes over 5 years (non-diabetic individuals)Med diet + olive oilCumulative survival from diabetesMed diet + nutsLow fat dietSalas-Salvadó et al., 2011
9PREDIMED Results30% reduction in risk of heart disease 52% reduction in risk of diabetes27% reduction in risk of heart disease with statin treatment30% reduction in risk of diabetes with metformin treatment(Taylor et al, 2013; (Knowler et al, 2002)
10What these results tell us… Greater adherence to a Mediterranean diet is more effective than current drug treatments to reduce the risk of heart disease and diabetes.

12Other health benefits of a Mediterranean diet Following a Mediterranean diet can:reduce the risk of Alzheimer's and Parkinson's diseasereduce the risk of death from or occurrence of CancerSofi F et al., 2010
13Summary Heart disease remains a major cause of death Good evidence that following a Mediterranean diet can reduce risk of heart disease and diabetesFurther research needed on how to support people to change their diet
15The Mediterranean diet High in fruits, vegetables, wholegrain bread, rice and pasta, potatoes, beans, nuts, and seedsOlive oil as an important fat source and dairy products, fish, and poultry (consumed low- moderate amounts)Eggs (moderate amounts), and red meat (low amounts)Wine is consumed in low to moderate amounts.Dietary pattern based on food patterns of many Mediterranean regions in 1960sKris-Etherton, 2001

23TEAM-MED Study Time 0 12 (months) 75 peopleat risk of heart diseasePeer support (25)Time(months)Written Mediterranean diet advice (25)Sessions with Dietitian and provided olive oil and nuts (25)We are currently working on the TEAM-MED study. The aim of this study is to examine different ways of supporting people, at risk of heart disease to change their diet towards a MD.We will recruit 75 individuals that are at risk of heart disease but who have no history of heart disease or diabetes. Individuals will be asked to follow a MD for 12 months and will be given different levels of support; 1 group will receive written advice, one group will receive sessions with a dietitian and olive oil and nuts and one group will receive peer support- which is a form of support provided by individuals that have experience of successfully making dietary changes to lower their risk of heart disease.
24TEAM-MED StudyTEAM-MED is seeking to recruit suitable people to take part in the study. If you are over 40 years, overweight and with no previous history of heart disease, stroke or diabetes you may be eligible to take part in TEAM-MED.For more details contact:Claire (tel: ) orSarah Moore: (tel: )
