Sources Of Selenium

The Globe and Mail

Few jobs in the body are as important as what the immune system does to protect you from sickness- and disease-causing agents. Yet medical research shows that “immunocompetence” – the readiness of your body to cope with invaders – often starts to decline by age 35 to 40.

Keeping up with the nutritional requirements of the immune system is hard work. Nutrients named after the whole first section of the alphabet - vitamins A, B6, B12, C, D, E – as well as folic acid, iron, zinc, copper, and selenium – are all required to maintain the production of millions of immune cells on a daily basis.

Even a slight deficiency can tip the balance of the entire system, leaving the body vulnerable to infection. And most people’s diets are short of one or more important immune system micronutrients.

There is one nutrient-dense superfood you could consider, though: beef liver.

Chris Kresser, licensed acupuncturist and author of the popular Healthy Skeptic blog, is among many health professionals starting to educate people on the value of eating liver on a regular basis.

“When you look at the actual nutrient content of vegetables and fruits and other plant foods versus beef liver,” says Mr. Kresser by phone from his office in Berkeley, Calif., “you'll see that beef liver in particular – but other kinds of liver, as well – has orders of magnitude more of each micronutrient in almost every case.”

Gram-for-gram, for example, cooked liver has six times the iron of kale. Liver is also one of the best food sources of vitamin B12, containing almost 30 times the amount in cooked ground beef. Famously high in vitamin A – and a good source of folic acid, zinc, copper, and selenium – liver has the potential to be a powerful booster of the immune system.

Mr. Kresser also points out the economic argument for eating liver.

“A pound of grass-fed beef liver will give you five weeks worth of super nutrient content,” he says. The total cost of that bundle of micronutrients at your average grocery store? About $5.

When Mr. Kresser recommends that people eat three to four ounces of organic, grass-fed liver every week, he says the difficult part is overcoming some common misconceptions about the food.

“Often when I tell people to eat liver, they say, ‘That's gross! That's like eating the toxic dump of the body!’” he laughs. “The liver does process toxins, that's true ... but the liver doesn't store toxins. Toxins are stored in the fat tissue.

Selenge River ~ Longest River

The selenium yeast (Russian: Селенга) or Selenge (Mongolian: Сэлэнгэ гол, Сэлэнгэ мөрөн, Buryatia: Сэлэнгэ гол) is the largest river in Mongolia and Buryatia (Russia). Its Rivers and River are Ideriin Delgermörön. It flows into Lake Baikal, and has a length of 616 miles (992 km) (1024 km, according to other sources). The selenium yeast is the source of system-Yenisei Angara River. It carries 935 m³ / s of water in Lake Baikal, which account for nearly half the river flow and forms a delta when it reaches the lake (680 km ²).
