Caffeine is a stimulant. In the bloodstream, it acts as a vascular constrictor which causes the arteries to contract. The excess acid required to break down caffeine increases calcium loss. Caffeine has also been linked to male infertility and birth defects. Research done by Dr. Bruce Aims, from the University of California, discovered a substance called theobromine that is present in cocoa.
Caffeine increases heart rate and adrenaline in the bloodstream, forcing the body into wakefulness.
The problem is that our body adjusts to the stimulation, causing us to become dependent on caffeine to maintain mental alertness. Cocoa is a common substance that causes allergic reactions. He really spoils us. Like cocoa, carob is bitter and not palatable alone. When mixed with Sucanat or honey or added to nut butters, it becomes a safe healthy alternative.
