Nutrition in leprosy: a review

Area of Science:

• Medical Science
• Nutritional Science
• Immunology

Background:

• Dietary factors have been linked to leprosy (Hansen's disease) since the early 20th century.
• Key nutrients implicated include vitamins A, B, C, D, E, calcium, and zinc.
• Much historical literature lacks detailed dietary data, especially when diet was not the primary research focus.

Purpose of the Study:

• To review the historical literature on diet and leprosy.
• To highlight the recognized impact of nutrition on the immune system.
• To advocate for increased focus on dietary interventions in Hansen's disease research.

Main Methods:

• Literature review of studies published between 1900 and 1960.
• Analysis of dietary factors influencing Hansen's disease etiopathogenesis.
• Synthesis of current understanding of nutrition's effect on the immune system.

Main Results:

• A significant body of literature suggests diet influences leprosy outcomes.
• Adequate nutrition appears beneficial, while deficient diets are detrimental.
• Growing evidence demonstrates nutrition's profound impact on immune function.

Conclusions:

• Diet plays a crucial role in Hansen's disease, affecting its development and progression.
• Understanding the link between nutrition and the immune system is key.
• More emphasis on diet is needed for controlling and preventing this global disease.
