Acai (Euterpe oleracea), an Amazonian fruit, has been studied for the possible effect of reducing arteriosclerosis (atherosclerosis). This is the result of reduction of absorption and production of cholesterol. This study was done on rabbits fed a high cholesterol diet. Some were treated for twelve weeks with acai and some were not. The treatment was with the fresh fruits blended with water.
After 12 weeks, extensive blood testing was done of blood lipids of both groups of rabbits for total cholesterol, HDL-cholesterol and triglycerides. Chemicals related to cholesterol metabolism (campesterol, beta-sitosterol, and desmosterol) were also tested.
The results of blood testing and the pathologic examination of the rabbit aortas demonstrated that the high cholesterol diet did increase the arteriosclerotic lesions in the rabbit’s aortas. However, the rabbits which were treated with acai had greatly reduced arteriosclerotic lesions in their aortas.
CONCLUSION: Rabbits on a high cholesterol diet which were fed acai showed better lipid profiles and less atherosclerosis than those which were not treated with acai.
