Reasons for malnutrition
Malnutrition can also occur due to an inability of the body to absorb nutrients from the food ingested, over an extended period of time. Body’s inability to absorb nutrients is sometimes seen after surgery or trauma.

These people have to rely on supplementation to obtain their daily dose of the above mentioned vitamins and minerals.
