Anemia is a medical condition where there is not enough oxygen supply in the blood, causing our tissues and organs to be deprived of oxygen needed to function. This is condition is largely related to a lack of iron, which is required in order for the body to create hemoglobin, which is the oxygen-carrying component of our blood. Without enough iron, the red blood cells cannot have enough oxygen-carrying capacity to meet our body’s daily requirements. 
People affected with mild anemia may simply feel fatigued throughout the day while more severe cases affect oxygen delivery to our major organs, damaging their ability to function adequately. Other symptoms of anemia can include weakness, pale skin, fast or irregular heartbeat, shortness of breath, chest pain, dizziness and cognitive impairment.
Here’s a great list of naturally iron rich foods to supplement your diet with. Stats are from the USDA nutrient database  – and note that in order to “keep it natural” we skipped the foods that have been artificially fortified with iron.
