Overview
Antioxidant-rich food; phenolic compounds studied for LDL/liposome oxidation inhibition and structural effects on glycosaminoglycans (GAGs). Dried fruit/leaves used for diarrhea; blueberry tea for sore throat/mouth-throat inflammation. Investigated for diabetes/hyperglycemia and possible UTI anti-adhesion effects (relative of cranberry).

Current use
Antioxidant-rich food; phenolic compounds studied for LDL/liposome oxidation inhibition and structural effects on glycosaminoglycans (GAGs). Dried fruit/leaves used for diarrhea; blueberry tea for sore throat/mouth-throat inflammation. Investigated for diabetes/hyperglycemia and possible UTI anti-adhesion effects (relative of cranberry).
Preparation
Fruit eaten raw/cooked/dried; tea from dried fruit or leaves; juice noted as MRI contrast agent (per course text).
Dosage guidance
No typical dosage listed in course text.
Cautions & contraindications
Blueberry leaf may decrease blood glucose and is contraindicated for people with diabetes (course text phrasing) and may affect triglycerides/test results. Avoid in pregnancy/breastfeeding due to lack of safety info (per text). Use caution with diabetes or people taking blueberry supplements; monitor for blood glucose lowering effects.
Evidence notes
Course text emphasizes polyphenols including resveratrol, ellagitannins, flavonols, catechins, anthocyanidins and proanthocyanidins. Notes a USDA study suggesting anthocyanins in whole blueberry preparations may not absorb well in humans; cooked blueberries may have lower resveratrol than raw.
