What food is highest in selenium?

I am looking for foods with the highest selenium content.

I have tried looking at USDA Se database and it just lists wheat as the highest but it's not clear where it is in comparison to other foods. I'm not looking for anything specific but rather a good ranking of what foods are higher and what foods are lower in selenium. Any help would be appreciated. Thank you!

This is actually a really easy question, it doesn't require any specific database because the selenium content of foods is well-known and agreed upon. The selenium content of foods is available here, however there are other lists you can find.

Selenium is naturally present in a variety of plant foods and is found in high amounts in legumes such as soybeans, peanuts and lentils. Whole grains such as wheat and rice contain more selenium than refined flour. For vegetables, the highest selenium content is found in garlic, broccoli, Brussels sprouts, cabbage and onions. Other fruits such as figs and kiwi fruit contain high selenium levels, but are somewhat rare, so this information won't be terribly helpful.

In terms of dietary selenium intake, the amount you can expect to get from various foods isn't huge. In this study, it was found that on average we only absorb up to 13% of the selenium from our diet. This amount is relatively low, and the researchers state it is difficult to determine what is the appropriate level of selenium in our diets. For more information, I'd recommend you take a look at this excellent web page.

What is the main use of selenium?

Selenium is a non-hazardous, non-radioactive chemical element.

It's a member of group 19 on the periodic table of elements and is commonly known as grey arsenic. Selenium is also a very important mineral in our bodies. In short, it makes healthy hair, healthy skin, proper thyroid function, protection against cancer and even helps protect the immune system.

It's believed that trace amounts of selenium are a pre-requisite for life. But, when excessive amounts of selenium are ingested over long periods of time it can be toxic. The human body lacks the ability to store selenium so it must be excreted. A number of studies have revealed that selenium helps prevent cancer.

Selenium helps the body make glutathione, an antioxidant. This is the body's chief anti-inflammatory and anti-oxidant, and selenium is needed for proper glutathione production. Glutathione helps your cells remove harmful free radicals, which can lead to a wide range of chronic health conditions. Research published in the New England Journal of Medicine found that selenium intake was inversely related to colon cancer risk. This study was a long-term follow up of people who had taken part in a previous trial where supplementation with a form of selenium was shown to lower colon cancer incidence. In addition, scientists recently found that daily consumption of selenium (found in foods, such as tuna) may significantly lower the risk of developing liver cancer. Even more surprising was the fact that the same risk reduction was found in people with cirrhosis of the liver.

Selenium's relationship with thyroid hormones isn't well studied, but it is known that some people cannot produce sufficient amounts of thyroid hormones because they are lacking selenium. What is the most common selenium supplement? There are a few popular forms of selenium that are available in supplement form. Each form has a different effect on the body and the benefits it offers. Iodised Selenium comes from iodine-selenium complexes that work by the principle of blocking the uptake of radioactive iodide from the thyroid gland.

There are two forms of this form. One version is referred to as I with an iodine (Iodine-131 and Iodine-127).

Selenium should not be taken for any condition that is being treated or being monitored by another person and it has never been recommended for any condition that has an active drug treatment available.

Before selenium supplements are available for purchase over-the-counter, selenium deficiencies are uncommon. Most people take selenium because they eat a diet with limited selenium intake. Those who do not eat an adequate amount of foods rich in selenium are usually deficient and may respond to small doses of selenium supplements in daily life. This group are not taking prescription drugs or over-the-counter treatments. All of the other medical conditions listed above need only minimal selenium as a micronutrient in daily life to maintain optimal health and wellness. If it is necessary to treat an acute illness, then low doses will be adequate. Any serious condition when on active treatment would require maintenance levels of approximately 300 mcg/day for adults, and 50 mcg/day in children.

Over-the-counter (OTC) selenium is also available, in a liquid, tablet, or capsule form. Some people with kidney or liver problems should avoid selenium supplements, if they have not first been checked by a doctor or dietitian to make sure these side effects are not common.

The Food and Nutrition Board recommendation for adults in good health is a minimum of 45 mcg/day, with no upper limit. The range of safe supplementation in children is 15-45 mcg/day for ages 5-14 years and 30-45 mcg/day in those of ages 2-4 and 15-17 years. For those on dialysis or having had a renal transplant, selenium should not exceed 30 mcg/day at any age.
