If you're concerned perhaps you could try to include the following foods in your meals.
Foods such as milk, cheese and yogurt contain calcium. So do dark leafy vegetables. Kale, turnip greens, broccoli, brussel sprouts and cabbage are rich sources of calcium. Canned fish (with bones), such as salmon, sardines and mackerel are also good choices.
Fruits rich in potassium include bananas, apricots, prunes, dates, cantaloupe, watermelon and strawberries. Foods such as salmon, beans, turkey and fish also contain potassium as do peas, greens, spinach and tomatoes. If you are consuming three of these items a day, you are probably getting enough potassium.
It is more difficult to get the proper daily amounts of magnesium through foods alone because fewer foods have high levels of magnesium. Almonds, cashews, pumpkin seeds and brazil nuts are some good choices. Barley, quinoa and whole wheat flour are others. Swiss chard, spinach and white and black beans are also important sources of magnesium.
Foods such as almond milk, rice milk, soy milk, various kinds of juices, breads and cereals are often fortified with calcium and can easily be added to your daily diet.
It may be important to find other sources of magnesium, as calcium competes for magnesium in the body. Too much calcium means even less magnesium. Taking a daily supplement can be wise, or you can relax in a hot bath and get your magnesium too. Simply add 1 to 2 cups of Epsom salts to your bath at night and enjoy a restful night's sleep. Proper magnesium is essential to restful and restorative sleep.
