| Study objectives | The target limiting salt intake to 6g per day is important for all adults, but in particularly so for people of African and Caribbean origin. These groups are more likely to develop - and are more susceptible to the effects of - raised blood pressure and hence heart attack, stroke and heart failure. Traditionally the biggest proportion of salt intake in people of African Caribbean descent in the UK is from salt added to cooking. However, components such as sauces used to prepare ethnic meals at home also have a high salt content. A previous study for Salt Awareness Day 2005 stowed in individuals with high blood pressure that, in spite of claiming that they reduced salt intake by half, the 24 hour urine analysis of salt was still high - around 10g/day, illustrating that the public are very confused about where salt is in the diet and how sodium relates to salt. The same study showed that most people (69%) find nutrition labels incomprehensible. Therefore, the aim of this study is to see whether education and advice for people of African-Caribbean descent in the form of a one-to-one training session addressing how to read a label and general education about how sodium relates to salt will result in a reduction in salt intake (as assessed by 24 hour urine collection). A control group comprising patients who claim to be making lifestyle changes, but who will not receive the educational session, will also be recruited. |

| Intervention | All visits will be at the Blood Pressure Unit. At the first hospital visit patients will be asked if they want to take part in this study. They will be given at least 24 hours to make this decision. If they agree (we call them to confirm this) we will arrange their first visit where they will bring back their signed consent form. Next patients will be randomised to either the experimental (n=20) or control (n=20) group by a person independent to the study. Both groups need to collect their urine for 48 hours from visit 1 (day 1) and from day 17 (visit 3) where they will be shown a wide variety of fresh and processed foods, taught how to read a label, taught what salt is and how sodium relates to salt etc. The patients will also be taught how to adapt recipes to include less salt. |

| Key inclusion criteria | The recruits will be adults (aged 18 years and over) of African Caribbean origin. They will be patients with hypertension referred to the blood Pressure Unit at St Georges Hospital, Tooting, London. The participants can be on or off blood pressure treatment, but they must say they have been trying to make lifestyle changes with respect to reducing their blood pressure. We have targeted people of African or Caribbean origin because these groups are more likely to develop - and are more susceptible to the effects of - raised blood pressure and hence heart attack, stroke and heart failure, than their Caucasian counterparts. |
