Blood acidity is important for general well-being, but may have added importance for athletic performance In an article for the Mercury News, Phil Wagner, M.D., director of SPARTA Performance Science, noted while many athletes may turn to fruit as a nutrient-rich snack delivering antioxidants and fiber to help exercise recovery, they might do better turning to vegetables instead. Wagner cited a review by Loren Cordain (Am J Clin Nutr. 2010 Feb;91(2):295-7) that detailed the health benefits of a more alkaline diet, including preventing osteoporosis and kidney stones, fighting high blood pressure and deterring muscle loss or wasting. While both fruits and vegetables can improve the blood’s acid/alkaline balance, Cordain’s review showed a three- to five-times greater effect from vegetables, particularly leafy green vegetables.
Wagner said he encourages athletes to consume fruits directly after workouts, as the higher sugar content can help replenish glycogen stores and enhance the muscle-building environment in the body. Vegetables should take a central place on the plate at every meal, and fill in as snacks. He added in working with athletes, he educates them about how greens enhance performance by preventing muscle breakdown via making the body more alkaline.
