I think the subject is greater in scope than just having a selenium deficiency, Dr. D has factored in each person's nutritional requirements into their SWAMI report. Although thanks for sharing that video..
It gave me a greater awareness to eat foods high in natural selenium.
Many foods high in selenium if we're rotating our food choices would be consumed.
Here are other foods besides brazil nuts that are high in selenium.
Fish (tuna, halibut, sardines, flounder, salmon)
Shellfish (oysters, mussels, shrimp, clams, scallops)
Meat (Beef, liver, lamb, pork)
Poultry (chicken, turkey)
Mushrooms (button, crimini, shiitake)
Grains (wheat germ, barley, brown rice, oats)
Here's more foods that most of us are already eating. Also note the side effects of overdosing (supplementing
with pills, not talking about eating high selenium foods)http://www.buzzle.com/articles/selenium-foods.htmlhttp://www.livestrong.com/article/531693-herbs-high-in-selenium/
