What
Are Nutritional Deficiencies?
The recommended daily amount
(RDA) of a nutrient is determined by how much the body needs to stay healthy.
Nutrients can be obtained in a variety of ways—from eating a varied diet to
taking vitamin supplements.
A nutritional deficiency
occurs when the body doesn’t absorb the necessary amount of a nutrient.
Deficiencies can lead to a variety of health problems, such as problems of
digestion, skin problems, stunted or defective bone growth, and even dementia..
Iron
Deficiency
The most widespread nutritional
deficiency worldwide is iron deficiency, which can result in anemia. Iron
is found in foods such as red meat, dark, leafy greens, and egg yolks. It helps
your body make red blood cells. When you’re iron-deficient, your body produces
a reduced amount of red blood cells. The red blood cells it produces are
smaller and paler than healthy blood cells.
According to the World Health
Organization, over 30 percent of the world’s population suffers from this
condition. It is prevalent in both developing and industrialized countries (WHO).
In fact, iron deficiency anemia affects so many people that it is now widely recognized
as a public health epidemic.
