Good article, I too was unfamiliar with the name jambura, although have heard of pomelo. I would challenge one comment that was made, and that is potassium reducing the risk of heart disease. I've not seen that established and would welcome seeing any reference on that. However, the role of potassium in proper heart functioning is well established, as its role in helping to maintain proper blood pressure - there is no doubt that proper levels are very important. The rest of the nutrient profile of jambura is impressive indeed. Thanks for sharing.
