pre conceive diet

Have any other ladies on here altered their diet before trying to conceive ? Like upping your intake of vegetable, wholewheat carbs, lean meat etc ? If you did can you reccomend a meal plan or book that might give me some easy lists of what foods to buy and eat daily ? Thanks in advance ! And also any recommendations for prenatal vitamins high in folate and iron? ❤️❤️ we aren't trying for at least another 6 months to a year but hubby really wants me to be in the routine of a healthy diet so the baby is being fed healthy as soon as we do conceive
