Effect of barley foods on cardiovascular health biomarkers

This study is looking at whether eating foods made from a special type of barley developed by the CSIRO can improve heart health. Barley contains a type of fibre that may help lower cholesterol and triglycerides (fats in the blood), both of which are linked to heart disease. Participants will eat barley-based foods as part of their normal diet and have blood tests to see if their cholesterol and other heart-related markers improve. The study will compare results when eating barley foods against a control period. You may be eligible if: - You are between 30 and 75 years old - Your blood triglycerides are between 1.7 and 4.0 mmol/L, and/or your total cholesterol is above 5.5 mmol/L - If you are taking cholesterol-lowering medication, the dose must remain the same throughout the study You may NOT be eligible if: - You have a known allergy or intolerance to barley or wheat (such as coeliac disease) - You have a bleeding disorder - You have a history of gut, kidney, or liver disease - You have participated in another study in the past 30 days - You are taking medications that affect cholesterol (such as psyllium laxatives, antibiotics, probiotics, or plant sterol margarines) Talk to your doctor about whether this trial might be right for you.
