1. Garlic Built the Pyramids

Ancient Egyptians, Romans, and Greeks fed garlic to workers, Olympic athletes, soldiers, and sailors. It was thought to be a performance enhancer (especially for men) and increase work capacity.
Modern science is looking into this. Turns out garlic improves exercise performance in rodents. Studies on athletic performance are mixed, but garlic seems to improve exercise-induced fatigue.
The biggest positive effects were shown in people with heart disease. A six-week course of garlic oil reduced peak heart rate and increased exercise capacity.
