Whole Foods is red hot again. Sales are surging.

Supermarket chain Kroge (KR)r made a big push into organic food and its stock has been routinely hitting all-time highs lately thanks to strong results. Whole Foods has also had to contend with a growing challenge from discounters like Costco (COST) and Walmart (WMT).

And the success of Whole Foods gave birth to a new crop of healthy food grocers such as Sprouts (SFM), Fresh Market (TFM) and Fairway (FWM). Trader Joe’s has been expanding aggressively as well.

Whole Foods co-CEO John Mackey candidly addressed the issue of competition during the company’s conference call with analysts Wednesday.

That may be true. But investors (and consumers) are happy to see that Whole Foods has at least taken some steps to shed the Whole Paycheck image.
