Healthy fats are integral to hormone production, particularly steroid hormones like estrogen and testosterone. These fats, from sources such as avocados, nuts, and olive oil, help in the formation of cell membranes and the production of cholesterol, a precursor for steroid hormones. Additionally, healthy fats influence the regulation of insulin and leptin, hormones that manage appetite and metabolism. Ensuring adequate intake of these fats supports balanced hormone levels, which is vital for overall health.
