Did you know that turmeric has shown to decrease mutagens in your system, i.e., compounds that increase the number of mutations which may lead to cancer? Cinnamon may help with blood sugar control by increasing the amount of phosphorylation on insulin receptors, thus increasing the amount of glucose translocated into cells for use or storage. Ginger may lower your cholesterol. Onions have been linked to decreased rates of stomach cancer.
Flavor your food often, and flavor it well with seasonings that are not salted. If you do this, you may reap unknown benefits that herbs and spices contain.
*Note: I do not recommend taking encapsulated herbs and spices, especially without approval from your physician.*
