Genistein

Genistein is an organic compound belonging to the class of isoflavones, which are a type of phytoestrogens. These substances are naturally found in some plants and have a structure similar to estrogen – female sex hormones.

Genistein is widely known for its content in soy products such as soybeans, tofu, and soy milk.

Effects of Genistein on the Body

In the human body, genistein exhibits antioxidant effects, contributes to maintaining bone density, and may have a beneficial impact on the cardiovascular system.

It is also believed that genistein may play a role in the prevention of certain forms of cancer, thanks to its ability to modulate cell growth and apoptosis (programmed cell death).

Genistein and the Keto Diet

From the perspective of the keto diet, the consumption of products containing genistein may be a subject of special attention.

The ketogenic diet involves minimizing carbohydrates and emphasizing high fat consumption. Although soy products are a source of genistein, they also contain carbohydrates, which may make them less desirable in the diet when strictly following the keto diet.

However, not all soy products are equally rich in carbohydrates. For example, fermented soy products can be included in moderation in the diet:

• Tofu (firm) – low carbohydrate content
• Tempeh – moderate carbohydrate content
• Soy milk – can vary, check the label
• Miso – moderate carbohydrate content

Additionally, there are soy products processed to reduce their carbohydrate content, making them more suitable for the keto diet.

Benefits and Potential Risks

The consumption of genistein-rich products can be beneficial due to its antioxidant properties and potentially favorable influence on hormonal balance.

However, it should be noted that an excess of phytoestrogens can impact the endocrine system, especially in men and women during menopause.

An excess of phytoestrogens, such as genistein, can lead to disturbances in the male body, including hormonal imbalance, reduced libido, increased fat tissue, as well as potential decrease in muscle mass and fertility issues.

Furthermore, individuals with sensitivity to soy products or thyroid disorders should exercise caution.
