Accordingly to Dr gillian McKeith....
"If your stools are light beige incolour of have a yellow appearance it's a sign that you have difficulty digesting fatty foods. You are also most likely deficient in essential fatty acids, the good fats.
Eat more foods with EFAs to help to metabolize the fats. Add fish, avocados, pumpkin seeds, sunflower seeds and sea vegetables such as nori and dulse to your diet.
Sprinkling 1 tablespoon of flax seeds over salad will also help normalise your stools."
Thank you for that - that's what i remebered from another thread and figured that it was possibly from all the junk she has eaten over xmas. Hopefully a few decent meals and veggies will get her back on track!!
