Birch sap: what does science say?
- A study published in January 2017 in the trade journal Baltic Forestry shows that birch trees that grow in industrial areas are (surprisingly) richer in antioxidants than their cousins grown in the wild. To explain this unusual discovery, the researchers hypothesize that these trees are undoubtedly more exposed to environmental stress, which leads them to protect themselves more by making more antioxidants.
