Fats play a crucial role in the production of hormones in the body, including sex hormones such as estrogen and testosterone. They are essential for the synthesis of steroid hormones, which regulate various physiological processes, including metabolism and immune response. Healthy fats, particularly those from sources like avocados and fish, support optimal hormone production and balance. Inadequate fat intake can disrupt hormonal levels, leading to issues such as infertility, weight gain, and mood fluctuations. Thus, incorporating good fats into the diet is vital for endocrine health.
