What types of carbs are okay for a very active 54 year old women on the paleo way of life. I have a very high-energy job-lots of walking, swimming and lifting at the pool I work. I also bike, run, swim, do crossfit, golf-basically very active lifestyle.

I keep reading about adding carbs for athletes on the grok diet, but unclear as to what type? Is this strictly yams or sweet potatoes?

Thanks for helping.
