Selenium: The Powerful Micronutrient for Health and Longevity

Share

Can incorporating selenium-rich foods into one’s diet improve overall health?

Selenium

Selenium is a chemical element and a micronutrient with antioxidant properties that protect cells from damage and increase immune function (University of Florida Health, 2023). It has also been linked to heart health and longevity. Most individuals in the U.S. can acquire a healthy amount of selenium through a balanced diet. Research has shown that selenium supports healthy aging and reduces the risk of heart disease. (Alehagen U. et al., 2021) (Zhang Y. et al., 2024) A recent study found a region in China where residents have sustained longevity with soil that is rich with selenium. (Li B. et al., 2024) The body does not produce the chemical, so it must be obtained through food or supplements. (National Institutes of Health Office of Dietary Supplements, 2024) However, excessive amounts can build up in the body and be toxic, causing gastrointestinal problems, hair loss, kidney failure, neurological issues, and death. (National Institutes of Health Office of Dietary Supplements, 2024)

Only A Small Amount Is Needed

The body only needs small amounts of selenium to support bodily functions, including thyroid hormone metabolism and antioxidant defense. Most adults need 55 micrograms daily, and pregnant and lactating adults require an additional 5–15 micrograms daily (National Institutes of Health Office of Dietary Supplements, 2024). Individuals can get selenium from many food sources, including Brazilian nuts, meat, seafood, vegetables, and grains. A large hard-boiled egg comprises 15 micrograms, a cup of cooked spaghetti provides 33 micrograms, and 3 ounces of cooked shrimp offer 42 micrograms of selenium. (National Institutes of Health Office of Dietary Supplements, 2024)

Individuals who eat healthy and eat various foods will meet their selenium needs. However, in some parts of the world, poor selenium soil may not provide enough of this mineral for individuals through their diet. (National Institutes of Health Office of Dietary Supplements, 2024) Low selenium intake is linked to a heart condition called Keshan disease, which may weaken the heart’s ability to pump blood. (National Library of Medicine, 2023) However, individuals are recommended not to take more than 400 micrograms daily.

Longevity

Various researchers are trying to understand the link between selenium and aging. A study associated dietary intake with increased telomere length (protein structures at the ends of chromosomes that protect DNA and help control cell division), a biological marker that may indicate aging and other health conditions. (Liang C. et al., 2024) Shorter telomeres generally indicate aging and disease progression. Another study suggests moderate amounts of dietary selenium may protect against cardiovascular disease and death. However, the observational study included data from over 25,000 adults but did not prove a cause-and-effect relationship between selenium and improved longevity. (Zhang Y. et al., 2024) Further research is needed before experts recommend selenium as an anti-aging dietary component.

Injury Medical Chiropractic and Functional Medicine Clinic

Selenium helps with cell growth and thyroid function and is known to increase immune system function. However, avoiding excessive intake is important, as high levels can be harmful. Injury Medical Chiropractic and Functional Medicine Clinic providers use an integrated approach to create customized care plans for each patient and restore health and function to the body through nutrition and wellness, chiropractic adjustments, functional medicine, acupuncture, Electroacupuncture, and various medicine protocols. If the individual needs other treatment, they will be referred to a clinic or physician, as Dr. Jimenez has teamed with top surgeons, clinical specialists, medical researchers, nutritionists, and health coaches to provide the most effective clinical treatments.
