Selenium: Nature’s Delicious Defender Projects Your Cells in a Polluted World
Selenium is a trace mineral that plays a pivotal role in maintaining our well-being, offering benefits ranging from supporting immunity to potentially reducing the risk of cancer. This post explores the easy ways to add selenium to your daily diet, its many benefits and the exciting scientific research with regard to cancer.
What Is Selenium?
Your body needs it in small amounts but cannot produce on its own. Found naturally in soil, water, and certain foods, selenium acts as a powerful antioxidant, helps regulate metabolism, and plays a key role in maintaining thyroid health.
Why Is Selenium a Great Supplement?
Selenium’s role as an antioxidant is one of its standout features. It helps combat oxidative stress by neutralizing free radicals—unstable molecules that can damage cells and contribute to aging and disease. This makes selenium a go-to for those looking to support their immune system and overall cellular health.
Selenium also aids in thyroid function by working with iodine to produce thyroid hormones, which regulate everything from metabolism to energy levels. Additionally, research suggests selenium may improve heart health by reducing inflammation and lowering the risk of plaque buildup in arteries.

Selenium and Cancer Prevention
Emerging studies highlight selenium’s potential as a cancer-fighting mineral. Its antioxidant properties help protect DNA from damage, reducing the risk of mutations that can lead to cancer. Some research has also linked higher selenium levels to lower risks of certain cancers, including prostate, lung, and colorectal cancer. Selenium’s ability to enhance the immune system further supports its role in cancer prevention.

CAUTION: It’s essential to note that excessive selenium can be harmful, so it’s best to focus on natural sources and supplements within recommended daily limits.
How to Get Selenium Naturally
The good news? Selenium is widely available in foods, making it easy to incorporate into a balanced diet. Top sources include:
- Brazil Nuts: Just one or two nuts a day can meet your daily selenium needs.
- Seafood: Tuna, sardines, shrimp, and salmon are rich in selenium.
- Meat and Poultry: Chicken, turkey, and lean cuts of beef are excellent sources.
- Eggs: An easy, versatile option for boosting selenium intake.
- Whole Grains and Seeds: Brown rice, sunflower seeds, and whole wheat bread offer modest amounts.
By including selenium-rich foods in your diet or considering a high-quality supplement, you can support your body’s defense systems and possibly even lower your risk of serious illnesses like cancer. Just remember—balance is key. With the right approach, selenium can be a small but mighty addition to your holistic health journey.
A note on the need to have a healthy environment to grow Brazil nuts

What if the soil is depleted, or its natural environment is compromised?
Without the orchids of the surrounding rainforest, the euglossine population cannot sustain itself, and the Brazil nut trees do not get pollinated. For this reason, Brazil nuts used for human consumption must be collected from the rainforest; they cannot be produced on plantations.
This is also the reason for good nutrient content. They cannot be mass produced like an almond for instance. Largest producer is actually Bolivia so products from here will be a good source. Look for organic and eat no more than 2/ day.
The Selenium excerpt from Dr. Moondust’s chapter in Comprehensive Clinical Oncology - [A Potential Role for Resveratrol & Other Phytochemicals in Cancer Chemoprevention and Therapy]
* Selenium - Glioma is the most common type of primary malignant brain tumour and current conventional therapy includes surgery followed by radiotherapy. Chemotherapy may be offered to patients in the event of recurrence, but the prognosis for malignant gliomas has not improved greatly in the last three decades.
There is ample evidence from epidemiological studies, laboratory-based research, and clinical trials that selenium is one of the most promising micronutrients for cancer prevention and therapy. This mineral may be considered among phytochemicals in so far as it is found in plant-based foods such as Brazil nuts, garlic, mushrooms, and whole grain.
Many reports suggest that it is able to induce selective apoptosis in various cancers in vitro. A compelling initial clinical study with skin cancer patients reported the important finding that taking 200 ug/day of an oral dietary selenium supplement reduced total cancer mortality and total cancer incidence by nearly 50%.
There was also a significant reduction in the incidence of lung, colorectal, and prostate cancers. However, the selenium supplement did not significantly affect the incidence of basal cell or squamous cell skin cancers (60). Further cell studies showed that selenium treatment of three human glioma cell lines had a significant inhibitory effect on the growth of these tumour cells. Apoptosis in the target cells was detected via nuclear chromatin condensation using electron microscopy. Mitochondrial damage, which is another hallmark of apoptosis, was also demonstrated in two of these three brain tumour cell lines ultrastructurally (61). Another study with brain tumour cultures suggested that selenium induces tumour cell-specific apoptosis (62).
