Spinach Plant Mitochondria commonly known as the powerhouse of cells seem to be greatly involved in cellular metabolism. Improved mitochondrial function may be extremely beneficial for humans as it averts a number of ailments. Well, it appears that nitrate can help in promoting mitochondrial function. A recent study from the Swedish medical university Karolinska Institutet claims that nitrate present in vegetables like lettuce, spinach and beetroot can boost the function of mitochondria.

The substance nitrate found in a variety of vegetables is believed to be converted into a molecule known as NO by the body. This molecule allegedly plays a pivotal role in a variety of bodily functions, including blood pressure regulation, the immune defense and cell metabolism. It was mentioned that even though nitrate is presumed to decline oxygen consumption during physical exercise, mitochondrial dysfunction paves way for diabetes and cardiovascular disease.

As a part of the study, investigators analyzed a team of healthy people consuming nitrate equivalent to 200-300g of spinach or lettuce for a period of three days. Participants were then made to perform a cycling task and samples from thigh muscles were scrutinized. The results were compared with similar samples from the same subjects when they had taken a placebo instead of nitrate. Professor Eddie Weitzberg, lead investigator and colleagues observed that nitrate ingestion remarkably improves the efficiency of the mitochondria. These mitochondria presumably employed less oxygen and produced more of the energy-rich substance ATP per consumed oxygen molecule.

The study was published in Cell Metabolism.
