This podcast covers the signs of trace mineral deficiencies such as hair loss, white spots on nails, low testosterone, anemia, fatigue, infertility, and swelling in the neck. Trace minerals are essential for enzyme function and can contribute to chronic diseases and cancer if deficient. Best sources of trace minerals are seafood, organ meats, eggs, seaweed or sea kelp, and high-quality sea salt.

Quick takeaways
Trace minerals are essential for enzymes in the body and deficiencies can manifest in various symptoms such as hair loss, low testosterone, and diarrhea.
Obtaining sufficient trace minerals from the diet can be challenging and deficiencies can contribute to chronic diseases and increase the risk of cancer.
Deep dives
Importance of Trace Minerals
Trace minerals play a crucial role in our body's biochemistry by serving as co-factors for thousands of enzymes involved in various biochemical pathways. Examples of trace minerals include zinc, iodine, selenium, copper, and manganese. Zinc, for instance, is involved in over 300 different enzymes, affecting alcohol breakdown, testosterone production, immune function, detoxification, and neurotransmitter synthesis. Iron, the most common deficiency worldwide, is essential for enzymes, collagen production, and oxygen transport. Selenium is crucial for converting thyroid hormones and acts as a co-factor for glutathione, a master antioxidant. Iodine is not only necessary for thyroid hormone synthesis but also plays a role in brain development and hormone regulation.
Challenges in Obtaining Trace Minerals
Obtaining sufficient trace minerals from our diet can be challenging due to various factors. Vegetarians and vegans might find it difficult to obtain bioavailable forms of zinc, mainly found in red meat, organ meats, and shellfish. Iron deficiency is common since the bioavailable form in red meat is different from that found in spinach. Selenium deficiency can impair thyroid hormone conversion and compromise antioxidant protection. Additionally, iodine deficiency, especially in pregnant women, can lead to brain development issues in babies. Poor agricultural practices contribute to trace mineral deficiencies in the soil, affecting the nutrient content of plants and, subsequently, the animals and humans that consume them.
Signs of Trace Mineral Deficiency
Deficiencies in trace minerals can manifest in various symptoms. Zinc deficiency may result in hair loss, white spots on nails, low testosterone, and diarrhea. Iron deficiency can cause anemia, fatigue, brittle nails, and hair loss. Selenium deficiency may present as infertility, fatigue, and hair loss. Iodine deficiency can lead to thyroid enlargement, lowered intelligence, and hormonal imbalances. These deficiencies can contribute to chronic diseases and increase the risk of cancer. Fortification of processed foods with synthetic vitamins may not compensate for the lack of essential trace minerals. Furthermore, elderly individuals and those living in institutions often have poor nutrient intake, leading to widespread deficiencies.
Today I want to cover the different signs of a deficiency in trace minerals.
Trace minerals are minerals needed in tiny or trace amounts. A few examples of important trace minerals are zinc, iodine, selenium, and iron.
Trace minerals are essential for enzymes, which are proteins that run the body.
Symptoms of zinc deficiency:
• Hair loss
• White spots on the nails
• Low testosterone
• Diarrhea
Symptoms of iron deficiency:
• Anemia (weakness, fatigue, cold sensation)
• Brittle nails
• Hair loss
Symptoms of selenium deficiency:
• Infertility
• Fatigue
• Hair loss
Symptoms of iodine deficiency:
• Swelling in the lower part of the neck
You might not notice any symptoms right away, but a trace mineral deficiency could contribute to all kinds of chronic diseases later in life. It could even increase your risk of cancer.
