2.) prevent carbohydrate absorption from the intestines, possibly reducing rapid rises in blood sugar and insulin after eating (Drink OJ! before meals!)
I discussed naringenin’s effects with Tieraona Low Dog, M.D., director of the Fellowship at the Arizona Center for Integrative Medicine and a leading expert on botanical medicine. She notes that naringenin does have some ability to prevent carbohydrate absorption from the intestines, possibly reducing rapid rises in blood sugar and insulin after eating. This could have some beneficial effect on weight management and metabolic syndrome (a combination of risk factors for obesity, type- 2 diabetes, and heart disease that include insulin resistance, high blood pressure, low HDL cholesterol, high serum triglycerides and excess abdominal fat).
3.) protects the liverDr. Low Dog also tells me that some research suggests that naringenin may have the ability to protect the liver.
Plasma kinetics and urinary excretion of the flavanones naringenin and hesperetin in humans after ingestion of orange juice and grapefruit juice
The flavanones naringenin and hesperetin exhibit estrogenic, anticarcinogenic and antioxidative properties. Orange juice and grapefruit juice contain high amounts of these compounds, and therefore their intake from the diet can be relatively high.
We conclude that because of the relatively high concentrations of flavanones in plasma after ingestion of orange juice or grapefruit juice, considerable health effects could ensue in individuals consuming them regularly.
