Many elderly are lacking of Vitamin D recently:


Vitamin D insufficiency can result in thin, brittle, or misshapen bones, while sufficiency prevents rickets in children and osteomalacia in adults, and, together with calcium, helps to protect older adults from osteoporosis. Osteoporosis (or brittle bones) is a global problem that has serious public health implications. Osteoporosis often leads to fractures of the hip, spine or wrist after only minor injury. These fractures lead to loss of function and disability. This has great impact on both the patients and their family. The consequences of hip fracture are severe. A recent local study showed that about 1 in 5 persons died within a year of sustaining an osteoporotic hip fracture and 1 in 3 became wheelchair bound or bedridden.

One of the most important roles of vitamin D is to maintain skeletal calcium balance by promoting calcium absorption in the intestines, promoting bone resorption by increasing osteoclast number, maintaining calcium and phosphate levels for bone formation, and allowing proper functioning of parathyroid hormone to maNatural sources

• A lack of iron in the diet may result in the development of iron deficiency anemia.
• The greatest need for iron is during growth or periods of blood loss.
• To ensure a diet adequate in iron: Eat a variety of iron-rich foods, eat foods high in vitamin C, and combine plant sources of iron with meat, fish and poultry.
• If iron is lacking in the diet, iron reserves in the body are used. Once this supply is depleted the formation of hemoglobin is affected. This means the red blood cells cannot carry oxygen needed by the cells. When this happens, iron deficiency occurs and anemia results
  

  • Girls in particular need to consume food that is rich in iron.As girls lose iron every month through menstruation.Iron from    meat ,fish and poultry is absorbed efficeintly.To increase the absorption ,combine with a glass of orange juice as vitamin C helps in apsorption of Iron.

  
  
• There are, however, a number of methods to improve iron absorption. One of these methods is to include foods rich in vitamin C in the diet. Good sources of vitamin C include citrus fruits and juices, tomatoes, strawberries, melon,leafy vegetables and potatoes. To have an effect, these foods must be eaten at the same meal as the iron source.
