The Acute Effects of Meals Rich in Saturated or Unsaturated Fatty Acids on Postprandial Lipaemia in Healthy Men — CocoHeart  

Cardiovascular Risk Factor Clinical Trial

Official title:
The Acute Effects of Meals Rich in Saturated or Unsaturated Fatty Acids on Postprandial Lipaemia in Healthy Men

Clinical Trial Summary

Current dietary recommendations suggest that lowering intake of saturated fats or replacing it with unsaturated fats will decrease the risk of developing cardiovascular disease. Coconut oil has gained popularity in recent years but it contains 90% saturated fat, which has higher percentage of saturated fat than butter. To date, only limited studies have determined the acute effects of meals containing coconut oil on blood lipids, but findings are inconsistent. Therefore, further studies are needed to address this knowledge gap and compare the postprandial effects of test meals rich in coconut oil with other sources of saturated fatty acids such as butter and unsaturated fatty acids (vegetable oils). A cross-over, double-blind, randomised acute postprandial study will be conducted in 15 healthy men. Participants will be assigned to consume the test meals rich in saturated or unsaturated fatty acids in random order on 3 separate occasions, with 3-4 weeks between each study visit. Participants will be provided with breakfast (toast with jam and milkshake, 50g fat) and lunch (toast with jam and milkshake, 30g fat). The anthropometric, blood pressure, arterial stiffness, and breath samples will be taken for each study visit. Blood samples will be collected for the measurement of fasting lipids, glucose, insulin, inflammatory markers, whole blood culture as well as blood clotting. Breath samples are collected for the measurement of gastric emptying as well as assessment of satiety using questionnaires (100 mm visual analogue scale) completed throughout the day. The findings from this study will contribute to the evidence base on how consuming meals rich in coconut oil influence the level of blood lipids as well as other biomarkers for cardiovascular disease.
