I receive a couple of different newsletters with the focus using Nutrition to improve Health.
Dr. Mercola

Because of the many different articles I have read from these newsletters, for the last few years my wife and I have been taking Turmeric and Ginger every day. These two spices might be able to help prevent all types of illnesses. They are cheap ways to increase our levels of health with no adverse side effects. We have found that if my wife takes too much ginger, her blood pressure tends to get too low if she is also dehydrated.
If you want to see how spices can help you live a healthier life, research different spices and you might learn how they can help you. All it takes is a little bit of your time.
An example of this is:
