Fertility can be supported through everyday habits, and this chapter takes a holistic view covering diet, supplements, exercise and stress. It encourages more fruit, vegetables, whole grains and lean protein, and explains that folic acid is the only supplement recommended before pregnancy, with a clear warning that taking too many supplements can be harmful to you and your baby. Moderate exercise such as brisk walking, swimming or yoga is recommended to help maintain a healthy weight and reduce stress, while excessive or intense exercise can lower fertility. The chapter also explains how chronic stress can affect hormones and ovulation, and suggests mindfulness and meditation.
