You're Not Getting Enough Fibre
Women need at least 25 grams of the stuff a day but majority don't hit that mark. There are many health benefits to be had if you keep your intake up, but one of the most rewarding is the lack of digestive trouble. Berries are a great source of both soluble and insoluble fibre (one has a laxative effect while the other slows things down, meaning they balance each other out) so get into them. Try and buy from an organic farmer's market so you're getting all the good stuff and none of the bad.
