Selenium is an essential mineral for many body functions. Recent research suggests that selenium has anti-aging properties and may protect against age-related diseases. The body requires very small amounts of this mineral, which is naturally present in many foods.
A recent study found that increasing dietary selenium intake is associated with longer telomeres on chromosomes, which affect cellular aging. According to this study, each 20-microgram increase in dietary selenium was linked to a 0.42% longer telomere among participants over the age of 45.
Selenium may combat aging and prevent health issues associated with aging, such as tumors, cardiovascular diseases, and neurological and psychological disorders. Some researchers believe that selenium reduces chronic inflammation, which is closely linked to aging.
Most selenium in the body is stored in muscle tissues, although the thyroid gland has the highest concentration of the mineral.
Adults require 55 micrograms of selenium daily. Pregnant women should consume 60 micrograms, which increases to 70 micrograms during breastfeeding.
However, selenium supplements should only be taken if tests indicate a deficiency and a doctor recommends it. Selenium intake can be increased by consuming the following foods:
- Tuna and sardines.
- Fish, particularly halibut.
- Beef and chicken.
- Shrimp.
- Cheese.
- Brown rice.
- Boiled eggs.
- Whole grain bread.
- Beans and lentils.
- Mushrooms.
- Brazil nuts.
