- Consumption of sun-exposed oyster mushrooms, a rich source of vitamin D, helps tuberculosis (TB) patients fight the infection
- TB remains one of the most lethal infectious diseases, especially in low-income countries, accounting for about 1.6 million deaths each year and drug-resistant strains make treatments even more difficult
- Oyster mushrooms can support first-line anti-TB drugs and are ideal for low-income countries since they are safe, inexpensive, readily available and easy to distribute to patients
Sun-exposed oyster mushrooms, which is a rich source of vitamin D, helps tuberculosis (TB) patients fight the infection better by boosting their immune system as well as improving their response to treatment, according to a recent study done at the University of Hohenheim, Germany by TibebeSelassie Seyoum Keflie, a doctoral fellow along with Hans Konrad Biesalski.
The findings of the study will be presented at Nutrition 2019, the annual meeting of the American Society of Nutrition.
Sun-exposed Oyster Mushrooms in Tuberculosis Patients
- The study team gave one set of TB patients (treatment group) sandwich bread fortified with 146 micrograms of vitamin D obtained from sun-exposed oyster mushrooms daily during the first four months of antituberculosis treatment
- After four months, 95 percent of patients who were given the fortified sandwich was found to fall in the category of the severity of TB on a scale of 1 to 5
- The treatment group were found to have significantly greater vitamin D levels compared to
- participants who did not receive the fortified bread. Over a third of the treatment group were no longer vitamin D deficient following four months of vitamin D from sun-dried oyster mushrooms
How Do Sun-Exposed Oyster Mushrooms Help TB Patients?Prior studies have shown that vitamin D (from sun-dried oyster mushrooms) stimulates the body to form an antimicrobial compound that is effective against the tuberculosis-causing bacteria. Although sun exposure can increase vitamin D levels, dietary sources become necessary when exposure to the sun is limited.
‘Sun-dried oyster mushrooms help tuberculosis (TB) patients fight the infection. These are ideal for low-income countries since they are safe, inexpensive, and easy to distribute to TB patients.’
Interestingly, fresh oyster mushrooms contain little or no vitamin D, and the fungus forms vitamin D only on exposure to the sun, very similar to the human body.
Future Research Plans
- The team plans to carry out more research on the effects of vitamin D and immunological responses in bigger and more diverse groups of patients with TB.
- They are also planning to try out different methods to dry oyster mushrooms in order to determine how the highest levels of vitamin D can be obtained
