Nutrition notes (60-1, p 1044)

*Calcium:* under 50 = 1,000 mg over 50 = 1,200 mg 4 servings of milk group or green leafy vegetables, caned sardines/salmon with bones, broccoli, Ca fortified OJ *Vitamin D:* helps absorb the calcium *Vitamin K, magnesium and potassium also all important*

gout

*Inflammation of joints due to elevated uric acid levels.* High uric acid levels cause crystals to form in joints and kidneys. Most commonly affected the great toe, knees, and ankles. Patients with gout are at an increased risk for kidney stones. Signs and symptoms include severe pain, joint inflammation, swelling, redness, heat, and high uric acid level in blood. Treatment includes relief of pain and inflammation and prevention of future attacks. Low purine diet (avoid red meats, soda, high fructose corn syrup, organ meats, and alcohol), weight loss, increase fluid intake. Meds to treat acute attack and prevent future attacks. NSAIDs for inflammation and pain. Cherry juice as a homeopathic treatment.
