Orange peels may hold a key to better cardiovascular health, new research shows. Recent research has shown that some gut bacteria help develop cardiovascular disease. When they feed on certain nutrients during digestion, gut bacteria produce trimethylamine N-oxide (TMAO). Levels of TMAO can help predict future cardiovascular disease, according to researchers at the Cleveland Clinic. Yu Wang and her team investigated the potential of orange peel extracts—rich in beneficial phytochemicals—to reduce TMAO and trimethylamine (TMA) production. Scientists tested two types of extracts: a polar fraction and a non-polar fraction. To get the polar fractions, scientists used polar and non-polar solvents...
