STORY AT-A-GLANCE
- As you age, respiratory muscle function — specifically that of the diaphragm — declines
- This can lead to breathing troubles, impaired airway clearance and a decreased quality of life in older adults
- Nitrates, which are found in beets, have been shown to improve muscle contractions in the diaphragm, helping to improve breathing as a byproduct
- This is important for general health, but can become especially important for fighting off severe symptoms from viral respiratory illnesses like COVID-19
