Detoxifying Ringworm Fungal Infection through Food | Selenium 🌰
Dear readers,
I recently wrote a post on fungal infections and a pure vegetarian diet. You can find it linked here:
And I want to follow it up with a very practical piece of nutritional advice, that is inclusive to vegetarians too!
One of the most important nutrients required for detoxifying the body from a ringworm infection in humans is selenium.
Selenium is an essential mineral that plays a vital role in the body's antioxidant defense system
Selenium deficiency has been associated with impaired immune function and increased susceptibility to infections, particularly through its incorporation into selenoproteins.
These selenoproteins, such as glutathione peroxidases and thioredoxin reductases, help neutralize reactive oxygen species and protect cells from oxidative damage.
Luckily, you can get selenium from food sources.
The 2000 report of the US Food and Nutrition Board implied that most dietary selenium is highly bioavailable: >90% of selenomethionine is absorbed; selenocysteine appears to be absorbed very well; ≈100% of selenate is absorbed.
This figure shows the different ways used to increase selenium (Se) content in foods, known as biofortification. There are two main types: genetic and agronomic biofortification. Genetic methods involve breeding or genetic engineering to transfer genes that increase Se content, like ATP-sulfurylase (APS) and selenocysteine methyltransferase (SMT), into plants. Agronomic methods involve adding Se sources, like selenite or selenate, to soil or feed supplements for animals, resulting in Se-enriched foods. Another method is using microbes in culture media to produce Se-enriched foods, such as Se yeast.
Dietary Sources of Selenium
The best food source of Selenium, is Brazil nuts.
Se from Brazil nuts is highly bioavailable, this table shows the impact of Brazil-nut supplementation on biomarkers for selenium:
Other sources are as follows. Here is a helpful infographic on various food sources with their bioavailability of different forms of Selenium
India happens to be one of the countries where the soil is rich in Selenium.

How Selenium works in the body
This figure by Ferreira et al., (2021,) illustrates the process of selenium (Se) absorption, metabolism, and distribution in the body. When we consume Se-rich foods in organic or inorganic forms, Se is absorbed in the duodenum, cecum, and colon of the digestive system. Inside cells called enterocytes, selenomethionine (SeMet) and selenocysteine (SeCys) are absorbed actively through specific transport systems, while selenate is absorbed passively. Once absorbed, all forms of Se are converted to hydrogen selenide (H2Se) and transported in the blood bound to proteins like LDL and VLDL. In the liver, H2Se is converted to selenophosphate (SePhp) and incorporated into selenoproteins as SeCys. These selenoproteins are then transported to various tissues, including the testis, kidneys, and brain, mainly in the form of selenoprotein P (SELENOP) through a process called receptor-mediated endocytosis involving receptors like apoE2 and megalin.
