Dr. Perricone also writes:
Perricone readers know that I have long advocated replacing that cup of coffee with tea—especially green tea. If you have not yet introduced green tea into your daily regimen, consider the following fascinating facts:
- Although black and green tea hail from the same plant (Latin names of the species are Camellia thea, Thea sinensis or Camellia sinesis), only green tea also obstructed the activity of beta-secretase, which plays a role in the production of protein deposits in the brain that are associated with Alzheimer's disease.
- The positive effects of green tea lasted for an entire week, while the enzyme-inhibiting properties of black tea only lasted for one day.
- Coffee has no effect on these enzymes.
