Hmm, just an interested female popping in- I too was curious about the dietary habits of excellent (female) freedivers. Here's a few tidbits I found:
Taken from

Do you have any special dietary needs or preferences that you feel helps your training?
Nothing special, although I do admit a strong weakness for the family size bag of Doritos on a daily basis! Do you have any recommendations regarding this topic? I don't do anything out of the ordinary.
I take a multivitamin, Vitamin C and Echinacea due to the high amount of stress involved in the sport of freediving. Stress breaks the immunity system down and if I get a cold right before the attempt, I'm screwed. But, I usually quit taking these a week before the actual record attempt. Since I was the first diver to willingly submit to drug testing before and after a record attempt, I am too paranoid that something like a filler in a vitamin could be on the B list of banned substances.
And from

Nope. I eat everything I want when I want it. I never did any diet. When you are preparing for a Record you will have a lot of pressure in top of you. I am not referring to the hydrostatic pressure but to the training, media, sponsors &. Which is even worst that the first one. So if in addition to this you force your body and mind to resist temptations. Normally I eat a lot of pasta, but because I love pasta I eat it even when I m not training!

...so from what I've read, it seems that it's almost a non-issue?! I suppose it's common sense to cut down on coffee, carbonated drinks, processed foods, and increase intake of raw food, leans meats, nuts, seeds, sprouts and complex carbohydrates. I also think it's a good idea to detoxify at least once a year.
