Potential Treatment for Diabetes
The peel of guava, not normally edible, may provide benefits if you have diabetes. A study published in the June 2010 issue of “The Indian Journal of Medical Research” indicates that studies in diabetic rats suggest its consumption results in a decrease in blood sugar and in cholesterol levels. Studies are needed to determine if these effects correlate to human test subjects. Do not eat guava peel as a treatment for diabetes without first consulting your physician.
