Beta carotene has been found to be of great use in the field of pharmaceuticals. Some of the diseases that beta carotene help to combat are as follows.

1. Respiratory health

Beta-carotene can improve pulmonary function significantly and help reduce symptoms of respiratory diseases such as asthma. Persons who consume healthy amounts of beta-carotene and citrus bioflavonoids experience reduced mucus secretion in the lungs, and the frequency of asthmatic attacks, shortness of breath and associated wheezing is reduced.

2. Anemia

Sickle cell anemia patients tend to have low levels of antioxidants, which protect cells from oxygen-related damage. Supplementing with beta-carotene may help correct the deficiency.

3. Diabetes

Type II diabetes commonly follows poor lifestyle habits, coupled with insulin dysfunction and gradual worsening of insulin sensitivity. It is believed that inflammation and oxidation play a significant role in the development of type II diabetes, affecting as far as the cells in the pancreas responsible for the production of insulin in the first place. Beta-carotene, in addition to fruits and vegetables having a lower glycemic index load, has been shown to decrease the risk of insulin insensitivity occurring.

4. Cardiovascular diseases

Epidemiological studies, including descriptive, cohort, and case-control studies, suggest that carotenoid- and β-carotene-rich diets are associated with a reduced risk of cardiovascular disease.

5. Erythropoietic protoporphyria

Erythropoietic protoporphyria is a type of porphyria associated with erythropoietic cells. Here, the enzyme deficiency occurs in the red blood cells. Beta carotene might help those with erythropoietic protoporphyria (EPP), by reducing the blemishes and splotches, when consumed in regulated quantities.
