  • Green tea and cacao may treat diabetes complications

    Author: AAP

A Brazilan study suggests green tea and cacao could help stop some diabetes complications.

Cacao and green tea contain substances that may help prevent and treat kidney complications and retinal lesions caused by diabetes, scientists say.

The findings are from a study at Brazil's Campinas State University, supported by the Sao Paulo State Research Support Foundation.

Jose Butori Lopes de Faria, co-ordinator of the study, said the project "proved, in a rigorous way", that cacao and green tea reduced the death of podocytes, the cells that restrict the transfer of proteins to urine.

"The transfer of albumin to urine is the main renal disorder in a patient with diabetes," the scientist said.


The beneficial effects of cacao and green tea were attributed to the presence of polyphenols, although, in the case of cacao, researchers found that it contained other substances that might help treat the effects of diabetes.

One of them is theobromine, an alkaloid that activates the nervous system.

Theobromine's possible benefits in the treatment of diabetes "had never been described before in specialised literature", ophthalmologist Jacqueline Mendon?a Lopes de Faria said.

The study was conducted on rodents with induced diabetes, and on cells from rodent and human tissues exposed to high concentrations of glucose to simulate diabetes.

Green tea and cacao are known for their antioxidant and anti-inflammatory effects. Tea might provide protection from cardiovascular diseases, while cacao lowers systolic blood pressure.
