Hormonal imbalances can cause problems from infertility to diabetes, but certain nutrients help keep your hormones balanced and your body functioning properly. Healthy fats from olive oil, avocadoes, nuts, and seeds, fiber from fruits and vegetables, and quality proteins from eggs, fish, and meat all help look after and support our hormone health. In contrast, pesticides from non-organic fruits and vegetables and artificial sweeteners in processed foods negatively impact our hormones.
