Hemoglobin emerges as a natural antioxidant defense in the brain

Did you know the same protein that gives blood its red color and carries oxygen throughout the body is also present inside brain cells? Hemoglobin, long celebrated for ferrying oxygen in red blood cells, has now been revealed to play an overlooked - and potentially game-changing - antioxidant role in the brain.

Eating over 60g of almonds a day may protect DNA and cut oxidative damage

A meta-analysis of eight clinical trials found that almond supplementation, especially at doses above 60 g/day, significantly reduced oxidative DNA and lipid damage and improved antioxidant enzyme activity in adults. The benefits varied by biomarker and were influenced by dose, preparation, and participant characteristics.
