Soy milk, soybean milk, coconut water: Is consuming a lot really a risk for breast cancer?

Today we will discuss an interesting topic about foods we are familiar with, namely soy milk, soybean milk, and coconut water. Many women may believe or have heard that consuming a lot of soy milk, soybean milk, and coconut water increases the risk of breast cancer because these foods contain substances similar to female hormones. But what is the truth? Let’s find out together.

 

Breast Cancer: The Number 1 Threat to Thai Women

Statistics from the National Cancer Institute, Department of Medical Services, Ministry of Public Health in 2022 show that breast cancer is the most common cancer among Thai women, increasingly found in women aged 35 and over. The incidence rate continues to rise. Several risk factors include:

        ๐  Genetics Women with a family history of breast cancer have a higher risk.

        ๐  Hormones Long-term use of contraceptives and hormone replacement therapy increases the risk.

        ๐  Lifestyle behaviors Being overweight increases the risk of breast cancer.

 

Female Hormones and Breast Cancer

The female hormones that play an important role in the development and growth of breast cells are estrogen and progesterone.

 

        ๐  Estrogen This hormone is involved in the development and regulation of the female reproductive system, such as breast growth and menstruation. Excessively high estrogen levels may lead to abnormal breast cell growth, which can increase the risk of breast cancer.

        ๐  Progesterone This hormone works together with estrogen, playing a role in controlling the growth of the uterine lining and maintaining hormonal balance in the body. Women with low progesterone levels may have a higher risk of breast cancer.

 

What Are Phytoestrogens and Where Are They Found?

The substances mentioned are called phytoestrogens, natural compounds with a chemical structure similar to estrogen. They are found in many plants, such as soybeans used to make soy milk and soybean milk, as well as coconut water. These substances have a structure similar to female hormones in the body but are weaker and do not cause severe effects like the hormones produced by the body itself.

 

Does Consuming Soy Milk, Soybean Milk, and Coconut Water Really Increase the Risk of Breast Cancer?

Soy milk and soybean milk are highly nutritious, rich in protein, fiber, and antioxidants. Studies have shown that consuming soy has positive effects on heart health and reduces the risk of vascular diseases. Similarly, coconut water is a refreshing drink that helps hydrate the body on hot days. Coconut water is also rich in antioxidants and various vitamins beneficial to the immune system and overall health.

 

Although they contain phytoestrogens, moderate consumption has not been shown by research to increase the risk of breast cancer. However, excessive consumption may cause undesirable effects because these beverages on the market may contain added ingredients such as sugar. Overconsumption can lead to high calorie intake and affect other aspects of health.

 

After reading this article, women can comfortably consume these drinks, of course, not in excessive amounts. Another important thing not to overlook is breast cancer screening, especially for women aged 35 and over. Screening is the best way to detect the disease early so that treatment can be timely. It may start with self-examination at home and regular mammograms combined with ultrasounds every year to monitor your body for any abnormalities.
