July 30 (Reuters) - The S&P 500 was on track for its flattest session in two weeks on Thursday as investors digested ho-hum corporate earnings and new data showed that the economy grew more quickly in the second quarter.

Procter & Gamble, Facebook and Whole Foods Market all fell after quarterly reports that left investors wanting more.

U.S. economic growth accelerated in the June quarter as solid consumer spending offset a drag from weak business spending on equipment, suggesting steady momentum that could bring the Federal Reserve closer to hiking interest rates this year.
