Potassium
Potassium has many important functions, including allowing nerves to respond to stimulation and muscles to contract (tighten), including those in the heart. It reduces the effect of sodium (present in table salt) on blood pressure. It helps move nutrients into cells and waste products out of cells.
My heart was bouncing from 90 to 145 yesterday.
Chicken, turkey, and fish are high in potassium. A small steak has 600-700 mg too. Beef heart, liver, and kidney are high in bioavailable potassium and other nutrients. My butcher mixes offal into my beef mince, and you hardly notice it when it's in a burger or pasta sauce. Or grind it in yourself—50% brisket with 25% heart and 25% liver. Or just 75% beef and 25% heart if you're particularly sensitive to the liver flavor. You can also soak the liver in milk overnight to take the iron flavor out.
Generally, reaching the daily value for every nutrient from foods is impossible—you would have something like a 15,000-calorie diet. Some good multivitamins like Life Extension One/Two per day and some Magnesium Potassium Aspartate are enough to keep everything in check.
What's really horrifying is that how closely cesium mimics potassium. Areas with heavy contamination of radioactive cesium are especially dangerous since the body recognizes cesium as potassium and tries to use it in the same way.
