Almonds and especially almond extract contain benzaldehyde, shown in Japanese clinical studies to exert an anti-cancer effect. So splash some into drinks and find creative ways to work this nut and flavoring into your diet. Brazil nuts are in the news too. In animal studies, they've been found to be more protective against cancer than pure selenium selenite. They also contain ellagic acid, which may remove or block cancer causing toxins. Adding a few of them a day to your diet sounds like a smart idea.
