Dr. Marianna Baum is a nationally and internationally acclaimed scientist in the area of nutrition, metabolism and HIV/AIDS. She was the first scientist to investigate the relationship between HIV infection and micronutrient status. After her large-scale NIH-funded studies showed deficiencies in micronutrients as the disease progressed, Dr. Baum and her team conducted clinical trials supplementing specific micronutrients. These NIH-supported studies showed that long-term micronutrient supplementation improved nutritional status and immunity, delayed disease progression, and improved overall quality of life in HIV infected individuals. Dr. Baum’s most recent studies involve the risks for HIV and Hepatitis C disease progression in the presence of drug and alcohol abuse, their effect on liver disease, its prevention and treatment.
