Chia Seeds for Breast Cancer

(GEMMA Trial)

This trial explores how chia seeds can benefit individuals with a specific type of breast cancer (HR+/HER2-) who receive abemaciclib with endocrine therapy. The researchers aim to determine if chia seeds, known for their high fiber content, can improve gut health and reduce treatment-related gut issues. Participants will either consume chia seeds before starting their cancer treatment or have their gut health monitored throughout their treatment. This trial may suit individuals with HR+/HER2- breast cancer who are willing to provide stool samples and are about to begin abemaciclib therapy. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could enhance cancer treatment experiences.

The trial protocol does not specify if you need to stop taking your current medications. However, since the study involves standard care therapy with abemaciclib and endocrine therapy, you may need to continue these treatments if you are already on them.

Research has shown that chia seeds are generally safe for individuals with estrogen-positive breast cancer. Some studies suggest that chia seeds, rich in omega-3 fatty acids, can be part of a diet to help manage breast cancer. These omega-3s also occur in foods like olive oil and walnuts.

No specific evidence indicates that chia seeds cause harm when used as a supplement for breast cancer. In fact, chia seeds are often recommended as a healthy addition to support overall well-being in people with certain types of breast cancer.

Researchers are excited about this trial because it explores the potential of chia seeds to modulate the gut microbiome in patients with breast cancer, a unique approach compared to traditional treatments like hormone therapies and chemotherapy. Unlike these standard options, which directly target cancer cells, the chia seed intervention aims to enhance gut health by increasing fiber intake, promoting a diverse microbiome, and reducing inflammation and dysbiosis. By doing so, it might not only support cancer treatment but also improve overall health and potentially minimize side effects associated with conventional therapies. This trial also seeks to understand how gut microbiome changes during treatment with abemaciclib can influence the development and severity of diarrhea, a common side effect, which could lead to better management strategies in the future.

This trial will evaluate the effects of chia seeds on breast cancer. Research suggests that chia seeds might help fight breast cancer. Some studies have found that chia seeds contain substances that can slow the growth of breast cancer cells by affecting certain molecules related to estrogen, a hormone that can sometimes promote cancer growth. Chia seeds are also rich in omega-3 fatty acids, known to help reduce inflammation. Since inflammation often links to cancer growth, these seeds might help lower that risk. Additionally, chia seeds are safe for people with estrogen-positive breast cancer, the type of cancer being studied here. While more research is needed to confirm these effects in humans, these early findings are promising. Participants in the Dietary Intervention Cohort of this trial will receive a 2-week chia seed intervention to assess its impact on the gut microbiome before starting abemaciclib.¹²³⁴⁶
