HELP ME PLEASEEEEEEEE!!! – Virtual Villagers 4 Review

I love the game a lot but, I REALLY need help! My villagers are starving, yet they keep having babies and harvesting their only source of food besides the mushrooms, blackberries. Now they've eaten everything and there is a bunch of females with little ones that I don't want to die! I scroll down the reviews for help but nobody has clear instructions on how to get them food! How do you cook the hard fruit? PLEASE ANYBODY HELP ME!
